2014/09/17 (W) Hooked Up

Leave a reply

I figured Darryll would be here on Friday but he called a little after 8 AM this morning to see if he could come today and finish up.  I was going to check around to see what sort of price and delivery I could get on the boiler conversion, but with Darryll coming this morning I decided it was not worth trying to save a hundred bucks and risk an even longer delay in getting the furnace converted.  I called TOMTEK back and left a message with the secretary, Virginia, to let Tom know that we were getting the gas hooked up to the house today and that we needed him to come convert the boiler at his earliest convenience.  I also assured her that we would be fine without the boiler for a few days as we are not yet into freezing temperatures at night.  The biggest inconvenience will be the lack of hot water for bathing and washing dishes.  Linda can use our microwave oven, induction cooker from the bus, and our electric toaster oven to fix a wide range of meals.  We also have a microwave oven on the bus as well as a Gaggenau 2-burner electric cooktop and we have a Jenn-Air electric range/oven/grill/fryer/etc. in the recreation room in the basement.  We checked out the Jenn-Air when we moved in but have never cooked on it.  Once I get the extension hose with quick disconnect for the new gas grill we will also be able to cook on that if we want or need to.  We do most of our laundry with cold water, so that is not an issue.

Darryll must have called us from the road.  We had just finished breakfast (re-heated homemade cinnamon rolls and fresh grapefruit) and I was headed outside to move the cars so he could back his truck up to the garage when he pulled into the other end of the pull-through driveway.  Most of his work today involved completing the connections from the natural gas meter to the new 2″ black iron pipe and the old 1″ pipe that currently feeds propane to the house.  All of that work was on the east end of the house so he parked his van there to be as close that location as possible.  His dad came with him this time to help out.

We let our dishwasher finish its cycle and then turned off the boiler, closed the gas shut off valve, closed the shut off valve for the line feeding gas to the range, grill, and old breezeway heater (since removed).  Darryll they shut off the propane to the house at the tank and disconnected the supply line and pressure regulator from the house. He disconnected the supply line on the other end from the pressure regulator at the tank and installed a plug in the outlet.  I used short lengths of 10AWG electrical wire to secure the covers on both propane tanks.  The wires are just twisted, and while easily undone, the covers cannot just be pulled up without untwisting them first.

The old pipe that carried propane into the house is below the gas meter to the left and the new 2″ pipe is at the level of the meter and to the right.  The consumer connection outlet from the meter is a 1.25″ threaded nipple coming out of a shutoff valve below the right lower corner of the meter.  Darryll came out of that nipple and installed an elbow going back towards the house, a short piece of pipe and then a T with the opposing ends horizontal.  From there he was able to adapt down to 1″ i.d. pipe going to the left behind the meter and gas line and use various fittings to bring it around and connect it to the old pipe sticking out of the wall.  He put a union in there to make it possible to assemble all of this.  He went to the right out of the T and used an adapter to go up in size to 2″ i.d. and then elbowed up and over to line up with the 2″ pipe running along the side of the house.  He extended the 2″ pipe and somewhere in there installed a 2″ union, again, to make it possible to assemble all of these pieces.  The number of fittings and the geometry of their assembly was fairly impressive but it was a very neat installation when he was done.

This was a big project, and although Darryll is done with his part of the work the project is not finished.  Rather than post photos as the work has gone along I will be creating a page on our website just for this project and posting several photo galleries illustrating the major steps.

We had a small bird of prey in the back yard this morning being badgered by four very large Blue jays.  When sitting on the ground with its wings folded in it was about the same size as the Blue jays, definitely too small to be a Red Tailed Hawk, but I could not get a good enough look at its wings, tail, or underside markings to identify it.  The Blue jays kept swooping down at it and then it would suddenly take flight and go after one of them.  It appeared to be fast and very maneuverable, so I think the Blue jays were playing a dangerous game.

I called Country Squire Fireplace and Lighting and talked to Bob.  We agreed on the 12 foot extension hose kit and Bob said he would get in on order today.  Country Squire only gets deliveries from their American Hearth distributor every other Friday and the 26th is their next scheduled delivery date.  If our order does not arrive then it will be another two weeks before it gets here.  Obviously we won’t be heating the living room before the furnace gets converted or cooking on the grill before we get the new range unless something goes very, very wrong with those items.

I got a call back from Valerie at TOMTEK to let us know they would hold a service appointment for us on Monday, assuming the part comes in by then.  By definition, that has to be acceptable as there isn’t anything I can do to change it.  I have been a bit annoyed with myself, however, for not checking on all of this sooner and contacting TOMTEK sooner so they had the part in hand when it was time.

While Darryll was working on the meter tie-in I unscrewed the brass flare fitting that connected the old propane fire logs to the 1/2″ i.d. black iron supply pipe.  I then removed the fire log unit from the fireplace and moved it to the garage.  There was already a plug sitting in the fireplace box for the end of the iron pipe, but I left that for Darryll to connect after he had spliced a shutoff valve into the pipe outside the house just before it enters the side of the brick chimney and goes into the firebox.

I noted that the dials on the gas meter had not moved since it was installed and pressurized on Monday.  Darryll finished the iron pipe connections, opened the outlet valve, and put natural gas to the house and the new 2″ iron pipe.  After the pipe filled with gas we noted the readings on the meter dials.  He checked for leaks with his soapy water solution and did not find any.  Darryll made a light pencil mark on the 1/2 cu. ft. per revolution (rotation) dial.  He then opened the gas valve to the library furnace and checked for leaks downstream of the valve.  He did not find any so he turned it on and set the thermostat up.  It took a couple of tries to purge the remaining air out of the line and get the burner to light, but once it started it ran really nice.  He then opened the gas valve to the garage furnace and checked for leaks downstream of the valve.  Again, he did not find any so he turned the power on at the ceiling switch, turned the thermostat on, and turned the temperature up to start the unit.  There was only a small amount of air left in the 1/2″ i.d. line and the unit lit right up and purred like a kitten.  (OK, roared like a small lion.)

These are not dramatic moments but they are significant ones.  After numerous visits spanning more than six weeks, and a myriad of steps integrating various technologies, you flip a switch and voila, you have a functioning furnace; or two, in our case.  Darryll let both furnaces run long enough to burn off some manufacturing oils which sometimes produce smoke from the supply registers and cause homeowners to freak out.  He shut the units off at the thermostats and waited to make sure they would actually cycle off.  They did, so there wasn’t anything left to do except pack up and head for home, stopping to get some lunch for his dad on the way.  He will mail us the final invoice once he has it figured out.  It’s nice to do business we people that trust us.

I called D. R. Appliance to let them know we had natural gas to the house and to find out what they do with the old units they haul away.  Curt said they would be able to bring the new unit and install it very quickly after they receive it.  There’s a chance that will be on Friday or Saturday, which would be really nice.  As I suspected (feared) they take the old unit to a dump.  I asked if they would drop it at Salvation Army but they were reluctant to do that, even though I did not see where it would be inconvenient for them.

According to Curt the Salvation Army is very picky about what they will take.  I figured they would go right past the donation center on their way back to the appliance store but Curt pointed out that their next delivery and installation might well be in the opposite direction and he clearly did not want his delivery/installer to go even a little bit out of their way to do this.  Fair enough.  What did not occur to me until later is that a company that sells new appliances might want to get old ones out of circulation.  If so, I think that is shortsighted; folks looking for a used (inexpensive) appliance at a Salvation Army Thrift Store were not going to be customers for a new one.

I called the Salvation Army Thrift Store and Donation Center in Brighton, Michigan, which is actually on Grand River Avenue as you go towards Howell from our house.  They said they would accept the old range as long as it was working.  I told them it was in reasonably good shape, looked OK, and worked fine except for the spark igniters for the stove top burners.  That was fine with them.  They just asked that we mention the spark igniters when we drop it off.  They also had a truck that could come get it if we were unable to get it into our personal vehicle and gave me the phone number to schedule a pickup.  Cool.  That means we don’t have to try and convince D. R. Appliance to deal with it and it does not end up in a scrap yard.

Although I did not do anything particularly physical today I was very tired by 4 PM and took a 2-hour nap.  Linda woke me up at 6 PM to have a dinner of green salad, leftover lentil stew with sweet potatoes and apples, and homemade biscuits with honey.

After dinner we opened a bottle of Alpha Rose wine that we bought in August 2013 at Red Trail Vineyard in Buffalo, North Dakota.  They are part of the Harvest Host network and it was the first place we used our membership to spend the night at a winery for free.  I posted about the place at the time.  The Alpha Rose was absolutely delightful with a very floral nose that carried over into the mouth.  Made from King of the North grapes, it was light but crisp and very pleasant in the finish.  I wish we had bought a case.  The King of the North vines were the first ones planted at Red Trail Vineyard back in 2003 and have done well in the North Dakota climate.  The Alpha Rose is only available at the winery and two other locations in the Fargo, North Dakota area, so I guess we will have to plan our travels to take us back that way.

Tonight was Season 5, Episode 6 of Doc Martin; at least it was for us.  I think Season 5 originally aired in 2010.  I really liked watching it on the TV monitor from a DVD compared to watching it on an iPad.

 

2014/09/05 (F) WordPress 4.0

Leave a reply

We awoke to temperatures in the low 70’s this morning and by noon it was forecast to be 85 degrees F with rapidly rising humidity.  We turned our A-C on yesterday and left in on overnight and through the day today.

WordPress 4.0 was released yesterday and just before midnight I updated the four websites I manage, including this one.  I was looking forward to working with the new version today, but first things first.  Darryll called at 8:15 AM to make sure it was OK to come over.  We finished breakfast and then opened the garage and moved a few things that might be in his way. Although we would have liked to continue working in the garage during the morning, before it got really hot and humid, we were glad to have Darryll here working on the HVAC installation.

Instead of working on organizing the garage Linda worked at her desk and baked a loaf of bread while I assisted Darryll.  He wired up the library thermostat and showed me how the wires were connected.  He installed the return air grill, which required some minor drywall trimming, and installed a 6″ combustion air duct in the ceiling of the utility closet.  The duct had a screen on one end with a hood, like a dryer vent, and was open on the other end.  He installed it from the attic side with the hood in the attic and the open end sticking down through the ceiling into the closet.  I may decide to caulk or apply drywall compound to fill that gap between the duct and the hole Darryll made in the ceiling.

Darryll’s main focus, however, was hooking up the four pieces of duct, two rigid and two flexible, that will carry conditioned air into the library and installing the two ceiling registers.  That involved working in the attic which was very hot.  The flexible duct for the two ceiling registers was the same kind of product that was used in the main house; a pre-insulated flexible accordion tubing with an 8″ inside diameter that comes in 25′ lengths compressed to about 3′ for shipping.  To feed the two registers on the lower part of the west wall of the library he cut lengths of 8″ diameter (circular cross section) metal duct and assembled them.  He attached them to the supply air duct (plenum) with flange connectors.  He then slide insulation blankets (tubes) around them and connected the bottom ends of the duct into the back of the register ducts using several elbows to bring the duct around and close to the wall.  Finally, he slid the insulation down and secured it.

While Darryll was doing all of that I finished connecting the AC power to the condenser/compressor. That involved the following:

  • removing the terminal cover panel from the inside of the fused disconnect box
  • knocking out access holes on the right side and bottom
  • mounting the fused disconnect box to the side if the house
  • cutting a piece of 3/4″ plastic conduit for the cable from the soffit to the box
  • running the NM cable through the conduit
  • installing a watertight 90 degree elbow into the conduit
  • attaching the elbow to the side of the box
  • cutting, stripping, and connecting the line wires
  • cutting the plastic armor on the hookup cable to the right length
  • installing a straight screw-in watertight connector on the box end of the armor
  • installing a screw-in 90 degree elbow watertight connector on the condenser end
  • cutting, stripping, and connecting the load wires in the box
  • cutting, stripping, and connecting the load wires in the compressor.

I had Darryll check my work and then installed the fuses in the pull-out disconnect but was not able to get it to plug all the way in.  Darryll bent the blades slightly and got it to seat fully.  (I need to get two different fuses.  All he had were 30A fuses but 20A would be sufficient.  Also, the fuses he had in his truck were notched on one end.  I think fuses with full barrels on both ends would be better as they would have more contact surface than the notched ones.)  I reinstalled the terminal cover panel and closed the box.  I then re-installed the cover panel on the A-C compressor that Darryll had removed earlier.

With the power connected and most of the ducts run, we turned on the 120VAC/15A circuit breaker (for the unit in the utility closet) and the 240VAC/20A circuit breaker (for the compressor/condenser).  Darryll turned the thermostat mode switch to “cool” and the fan switch to auto and the A-C came to life.  Hooray!  I love it when that happens.

While Darryll finished installing the ducts and the registers I connected and mounted the thermostat for the garage furnace and then connected the wires on the other end of the cable to the terminals on the back of the unit according to Darryll’s instructions.  I removed the end panel from the Reznor ceiling-mounted garage furnace, removed the documentation packet from the inside, checked that the gas valve was in the “on” position, and put the end panel back on.  I also removed the protective plastic film from the bottom of the unit.

Darryll gathered up his tools, extra parts, and unused materials and loaded them in his truck. He then pressurized his portable air compressor and used it to pressurize the black iron gas pipe.  It has not been holding pressure, so he pumped it up to 15 PSI and we went in search of leaks with a spray bottle of soapy water.  We used my inspection mirror to see behind and under connections and found three leaks.  One was in a 2″ pipe fitting behind the garage, one was in a 2″ pipe fitting near the end of the run by the generator, and one was at an elbow in the 1/2″ pipe where it exits the utility closet on its way to the garage furnace.

Darryll was checking air temperature readings at the registers and in the main plenum of the library HVAC unit.  The library was 89 degrees F when he first turned the A-C on, and the attic was a lot hotter than that.  He connected his gauges to the compressor/condenser and said the readings were close enough to correct that he did not want to add or remove any refrigerant until the room had cooled down and stabilized at the requested temperature.

I was hoping he would get the job finished today but he needed some equipment, which he did not have with him, to work on the iron pipe and he was obviously tired from a long day working in the high heat and humidity.  He may be back tomorrow; if not, Monday or Tuesday. Whenever he returns, I have complete confidence that he will get it done before the gas meter is hung and that it will all work correctly for many years with very little attention other than changing a filter once or twice a year.

We deferred lunch until Darryll left.  We had chickpea salad on a slice of the bread Linda had baked earlier, corn-on-the-cob, and the last of some fresh pineapple.  Nothing says “summer” like organic, non-GMO corn-on-the-cob.

After lunch I called Bratcher Electric to check on the status of the estimate/quote that Mike was putting together to service our generator, convert it to natural gas, and run a 100A Service Entrance Cable from the transfer switch to the garage panel, converting it from a sub-panel to a main panel.  Karen said they have been really busy but he would work on it over the weekend.

I also called 1-800-Pack-Rat to arrange pickup of the storage container on Friday September 12th.  Steven was not able to schedule the pick-up during the call and said he would contact the local office and get back to me.  I made it clear that we did not want to roll over into another billing cycle and I was calling one week ahead of time as we had been instructed.  He assured me that it would not be a problem.  About an hour later we got a return call and follow up e-mail confirming pickup for Friday, September 12.

Late afternoon I checked on the library A-C to make sure it was not freezing up.  Everything looked OK.  The thermostat was set to 76 degrees F and the temperature was down to 77, so I bumped the setting up to 78 to let it cycle off and on.  Although Darryll did all of the heavy lifting on this project (literally) I spent my fair share of time in the attic on warm days installing the pull-down folding ladder and working on electrical wiring and attic lights.  It was very gratifying to see that all of this work—his, mine, and Linda’s—finally result in something that operated correctly.

We were relaxing and reading when severe weather watches and warnings for our area started arriving on our iPads.  Naturally we went outside to see what was going on.  We were both born and raised in the Midwest, the St. Louis, Missouri area, to be exact, and as kids in the 1950’s, threatening weather was a form of summertime entertainment.  Not that we were stupid; we learned from the adults around us when the show was over and it was time to head to the basement.  When I was about 5 years old we lost a plum tree in our backyard to a close encounter with a tornado.

The gathering storm. The clouds were very dramatic in all directions.

The gathering storm. The clouds were very dramatic in all directions.

The clouds were very dramatic but eventually gave way to a formless mass of gray with swirling winds and a few raindrops.  We checked the Weather Channel app and the Weather Underground Wundermap app on our iPads.  The radar returns showed that we were likely in for some rain, and we got some, but as often happens the worst of it passed north and south of us.  The rain we did get was very welcomed.  We had heavy rain on Monday (Labor Day), Keith mowed the grass on Tuesday, I spread grass seed around on Tuesday and Wednesday, and a flock of six wild turkeys feasted on the grass seed on Wednesday and Thursday. We needed a nice light rain to help the seeds germinate and take root rather than be eaten or washed away in a thunderstorm.

Storm clouds looking east.

Around 7:30 PM our power flickered several times and we received e-mail messages from our generator letting us know that utility power had been lost and then quickly regained.  We decided to check the Kohler OnCue software to see what the generator was doing.  We thought sure we had installed the software on Linda’s computer, so we could monitor it from her desk in the kitchen/dining area, but it wasn’t there.  After much searching and head scratching we checked my old laptop and there it was!  When we thought about it we realized that the generator had been installed about a week before Linda started configuring her new Samsung laptop, so there was no way we had put the software on her machine.  We’ve been very, very busy the last 20 months, so it was not surprising to us that we had forgotten the exact sequence of events.

20140905-08295

Approaching from the southwest the clouds got more ominous.

The severe warnings expired at 8 PM and the severe watches at 9 PM, but that did not mean the rain was done.  A big fetch of moisture was located south of Chicago, Illinois and moving through southwest Michigan in our general direction.  The rain was forecast to continue into the early hours of tomorrow but be done before sunrise.  When the rains finally came it rained hard for a while.  Tomorrow is forecast to be a perfect Michigan day and I plan to buy another bag of grass seed to spot seed the areas that got washed away, again.

 

20140827 (W) HVAC and Dentistry

Leave a reply

The only thing these have in common (for me at least) is that they occurred on the same day.  Darryll and Alec were back this morning to continue working on our garage furnace and library HVAC project and I had a 2 PM dentist appointment to have them check if I had lost a piece of one of the abfractions they did back on June 17th.

Our dentist is in Dearborn some 50 miles to our southeast, so I try to leave 90 minutes for travel.  I got there ahead of time and they got me in about 15 minutes early.  It was a quick appointment but I was glad I went.  The hard piece of material I crunched while brushing my teeth a few weeks ago was, indeed, the abfraction material from the upper outside of tooth #11.  They replaced it under warranty and I was back on the road by 2:30 PM, which allowed me to make the trip back towards home somewhat ahead of the afternoon traffic rush.

These mushrooms appeared in the yard a few days ago as round balls and then opened up.

These mushrooms appeared in the yard a few days ago as round balls and then opened up.

I needed a saddle connector and Linda needed some “power greens” for our dinner salad so I exited I-96 at Grand River Avenue and headed towards Brighton.  There is a Home Depot right there, but they only had the 3/8ths saddle connectors in bags of five.  I only needed one, which I knew I could get at Lowe’s in Howell.  Traffic headed back towards Howell on Grand River was badly congested so I used a back route, taking Challis Road to Chilson Road to Latson Road.  The Lowe’s and Meijer’s are on opposite sides of Grand River Avenue at Latson Road.

By the time I got home Darryll and Alec had left.  Darryll had indicated they would knock off early and that he would be back next week to finish up.  While they were here they set the library A-C compressor/condenser in place by the west wall of the garage and got the refrigerant lines run, the power cable routed, and the control cable run.  They also cut the openings for the two lower supply registers in the library, installed the through-wall duct work, and the register grills.  Darryll will be back during the latter half of next week to finish up.  That gives me plenty of time to finish drywall work.

Summer is coming to an end.  The parochial schools are already back in session and the public schools start on Tuesday next week.  Lots of folks are heading north for the upcoming holiday weekend which marks the end of the summer tourist season.  Fall colors have already appeared on a variety of trees in our part of the county and a few seem somewhat advanced.  Except for the last few days, it has been a cool, moist summer.

Early this morning I e-mailed Shelly from the AT&T Office of the President thanking her for calling us on Monday in response to our Michigan Public Service Commission complaint filing that morning, and for following up with her contact information by e-mail.  Our phone line is still noisy to the point of being useless, but we have not seen the dreaded “Check Tell Line” or “Line In Use” messages on our phone and the DSL has stayed connected as near as we can tell.  I am not aware, however, that AT&T has actually done anything yet to fix the problem.  They certainly have not communicated any such information to us  Unfortunately working on the SLAARC WP website and creating user accounts absolutely requires me to be reliably online, as does the Intro to Linux course I am (supposed to be) taking through edX, so these tasks may have to wait until our AT&T DSL connection has been solid for a while.

 

2014/08/22 (F) Radio Flyer

Leave a reply

Today was mostly about drywall.  Most of the drywall on the lower half of the east garage wall was removed by the previous owners to access and repair baseboard heating pipes that had frozen (they used water in the system instead of coolant).  We also have a 19″ h by 29″ w opening higher up in that same wall where the window air-conditioner was installed.  (It cooled the breezeway by dumping heat into the garage.)  We needed to replace the lower drywall and patch the A-C opening before Darryll returned next week as he will be running supply air ducts down the wall at two locations to feed through the wall into the library just above the hot water baseboard heat radiator.  Before installing the drywall, however, we had some prep work to do.  When Linda wasn’t helping me she broke down cardboard boxes and got them ready to go to the recycling center tomorrow.

On the lower part of wall I drilled through the corners of the two register locations Darryll had marked on the library side.  We then added horizontal wood 2×4 blocking above and below the locations of the two registers.  We also added blocking around the inside of the old A-C opening to provide backing and attachment surfaces for the drywall.

With the carpentry done we removed some old insulation that was not in good shape and insulated the lower section of the wall.  I marked the locations of all the studs on the floor and on the upper half of the wall.  I also marked the locations of the horizontal blocking, the hot water heating pipes, and the capped off gas pipe that supplied the wall-mounted propane heater in the library.  Finally, we were able to install the drywall.  It took two pieces, 48″ x 87″, to cover the lower half along with lots of screws.  By the time we finished it was time for lunch.

We needed another sheet of drywall to cut the two pieces for the A-C opening, so after lunch we drove to Lowe’s and bought a 4′ x 8′ sheet.  When we got back we cut the two pieces and installed them.  Linda then helped me apply self-adhesive fiberglass tape to all of the seams.

The next step was applying drywall compound.  While I “mudded” the drywall seams and screw head dimples Linda started assembling a Radio Flyer configurable tricycle.  She ordered it for our grand-daughter a couple of days ago (Amazon Prime) and it arrived late yesterday.

I finished the first coat of drywall compound at 6 PM and cleaned up my tools.  While Linda pulled together leftovers for dinner (potato lentil curry, sautéed green beans with garlic, and naan bread) I measured the tow bar on the back of the bus to see how long of a cable we needed for the EZ*Connector system.  24″ + 34″ = 58″, about 5 feet, so their standard 6′ cable should be a good length.  Although it was only 3 PM in California, I decided to wait until Monday to place an order as I still needed to determine some circuit details.

After dinner I tried to check my e-mail and discovered that our DSL connection was not working, again, even though the AT&T gateway said it was.  The phone (POTS) had gone out earlier in the day and was out again.  I called Ken, the AT&T technician, and left a message and then called Steve, the AT&T infrastructure manager for the Howell and Lansing areas, and left a message.  I had called both of them twice this week already without getting a return call from either one.  My message this time indicated that I expected a return call with some information as to what they are doing to try and resolve the problem.

I called Chuck (on my marginal connection Verizon cell phone) to get a status update on his bus tachometer, then called Mike to firm up arrangements for him to bring his oscilloscope to breakfast tomorrow so we can go to Chuck’s shop and investigate the signal feeding his tachometer.  I texted Chuck back to confirm that we would be there by 10 AM.

I helped Linda finish assembling the Radio Flyer tricycle.  It is very spiffy and, of course, very red.  We spent the rest of the evening reading.  As I was typing this post I realized that I forgot to insulate the wall cavity where the window A-C unit was installed.  That meant I would have to remove the piece of drywall on the library side, insulate the cavity, and then cut and install a new piece of drywall.  I had already applied the seam tape and initial coat of drywall compound, so it will be a messy task.  Fortunately, I do not make those kinds of mistakes very often.

 

2014/08/20 (W) Like A Well-Oiled Clock

Leave a reply

Darryll and Alec (DCM Heating & Cooling) were back today to continue working on the garage and library HVAC project.  I was talking to them as they unloaded tools and materials when I got a call back from Paul Keech.

Paul has changed the name of his company from Paul’s Tree Service to Detroit Tree Recycling and is also running American Mulch.  As I was told yesterday he is trying to focus on tree removal, especially wood lots with multiple trees, rather than tree trimming.  Among other reasons, the trees he removes provides the raw material for his mulch business.  Also, the guy who did most of his climbing the last ten years has moved on to another job and it’s hard for Paul to run a business when he’s up in a tree, even with a cell phone.  I tried to describe the trimming and removal work we need done but in the end we agreed that I would take some photos, put them in a Dropbox folder, and e-mail him the link.  He also encouraged me to get a couple of quotes from some companies more local to our new location.

While I was talking to Paul, Darryll found a small leak in the reducer at the T-fitting behind the garage and tightened it.  The pipe out of this reducer will bring gas into the garage and was the last piece of pipe they worked on the last time they were here.  Alec reset the pressure to 12 PSI and it appears to be holding better than it has up to this point.

In the course of the day, they…

  • …finished setting the Library furnace/air-conditioner and connected the parts together.
  • …cut the hole for the return air register and installed the return air duct.
  • …ran the supply air ducting from the top of the unit along top of the ceiling, over the top of the utility closet door, and then angled it to run along east wall at the ceiling.  All of the duct outside the closet is insulated.  Two flexible ducts will come off the top and run through the attic to supply air through ceiling registers on the east end of the library.
  • …marked the location for the two registers that will be at the bottom of two rigid ducts running down the east garage wall to supply air to the library just above the baseboard heat radiators.
  • …removed the old library window A-C unit and covered the hole with cardboard.  We will have to patch the opening on both sides with drywall and paint it.
  • …shut off the propane to the old library wall-hung space heater, removed the unit, capped the line (iron pipe), turned the gas back on and checked for leaks.
  • …connected the double-walled flue pipe for the library furnace.
  • …connected the double-walled flue pipe for the garage furnace.
  • …ran the 1/2″ iron pipe for the gas supply to the garage furnace.

They will take care of the air-conditioner condenser/compressor installation on a subsequent visit.  In the meantime I need to install electrical junction boxes for the two furnaces, which must have switches located within three feet of each unit.  I also need to run new 12 AWG 2+g NM cable for old A-C condenser/compressor and repurpose the existing A-C condenser/compressor wiring as an outside 120 VAC / 15 Amp outlet.

We still needed to repair drywall in the library and upper east garage wall and install new drywall on the lower east wall of the garage and on the new utility closet walls.  The lower half of the east garage wall is the next thing I have to do as I need to have it done before he comes back to finish the duct work.

I got a call from Chuck Spera just before noon letting me know that he was headed to his shop to pick up his old VDO bus tachometer and take it to Bob’s Speedometer Service on Bergin Road.  Bergin is an east-west road about one mile north of our house.  Bob’s was over at Old US-23, less than five minutes away.  I met Chuck there at 12:30 PM and we met with Matt who handles their VDO instrument repairs.  He tested Chuck’s tach and pronounced it broken but probably repairable, so Chuck decided to leave it there.

Matt did confirm for us that both the tachometer and the speedometer take a square wave input signal in the 3 – 5 volt range with deflection of the needle proportional to the frequency of the waveform.  Presumably this same signal regulates the speed of a motor that drives the gears of the odometer.  I had discussed this very situation with Mike (W8XH) just last night and he is willing to bring his 100MHz 2-channel storage oscilloscope and help us look for and trace these signals if needed.  Once we have known good gauges installed knowing what waveform to look for will help greatly with troubleshooting should they still fail to indicate the appropriate information.

After we were done at Bob’s I headed over to the Meijer’s northeast of M-59 and US-23 to get a few things for Linda.  By the time I got home, Glen Williams of Tenor Clocks LLC had arrived to service our grandfather clock.  I “broke” it about a month ago by trying to wind it at just the wrong time and it has not chimed since then.  It has also never been oiled in the 11 years since we bought it and Glen told us on Saturday that it should be cleaned and oiled every 5 – 7 years.  (We saw Glen at the GLCC/CCO rally in Clio, Michigan this past Saturday when we were there.)  Glen took the mechanism out and examined it and said that nothing was broken.  Apparently it finally bound up the last time I wound it from lack of proper oiling.  He cleaned it, oiled it, and checked it for wear but did not see any.  He reassembled it, checked the operation and timing, and said it was running smoothly and keeping very accurate time “…like a well-oiled clock.”

Although my time on the computer today was limited, I managed to post my blog entry for August 1st and started selecting photos for other posts.  I updated the Technical page on the SLAARC website with a document on low band antennas for Field Day use, and added a link to an online Smith Chart Tutorial.  I then updated the online roster.  I am at the point where I need to generate WordPress user accounts for the club members so I looked more carefully at the WP-Members plug-in documentation to see if there was a way to have the website e-mail each member as I create their account.  It appears that there is, but it will take a little more work on my part to get that set up and working correctly.  As I was working on this our AT&T DSL line started dropping out; again.

Linda spent part of the day preparing food ahead in advance of having company tomorrow.  She held back some of the crushed red lentil soup for our dinner and served it alongside sandwiches.  While we were eating we noticed that the phone said “Line In Use.”  We knew we were not using it, but I picked up one of the handsets, pushed “Talk”, and got a very loud, very noisy busy signal.  We checked all of the phones to make sure there wasn’t a problem with one of them.  There wasn’t.  When I checked again the message said “Check Tel Line.”  That usually means we won’t have a dial tone when we push “Talk” and that was, indeed, the case.

Ken is the service technician that has been out twice to try to resolve the problem and he left his AT&T cell phone number in case we had recurring problems.  He also left his manager’s name and phone number.  I called and left a message for Ken and then called and left a message for his manager, making it very clear that Ken has been working hard to resolve our problem and we are happy with the service he is providing.  I also tried to convey that the service disruptions are interfering with our ability to do things online, like edit websites.  It’s bad enough that the data rate is so slow, but we depend on our “always on” DSL service to always be on.

We went to Lowe’s after dinner to buy a couple sheets of drywall.  We looked for special cover plates with a switch opening in one half and a round hole in the other, but did not find anything like that.  We stopped at Teeko’s on the way back and had Jeff roast two more pounds of half-caff blends for us; one Ethiopian Yirgacheffe and the other Seattle Blend.  He was still out of the Sweet Dreams decaf blend, which we have him mix 50-50 with the regular Seattle Blend to make Sweet Seattle Dreams, but he is supposed to be getting some in his shipment tomorrow.

Back home we unloaded the drywall, had some fresh strawberries for dessert, and read quietly for a while.  I’ve been reading the PDF version of the 2nd edition of The Mobile Internet Handbook and am done except for the glossary and the appendices.  It is over twice as many pages as the 1st edition and is the definitive resource on connectivity for RVers in particular.

 

2014/08/06 (W) Arrival And Departure

Leave a reply

Well, almost.  We were up and dressed by 7 AM, had some of the granola that Linda made yesterday (soooo good), and got to work while it was still cool in the garage attic.  Our first task, however, was to straighten up the garage as we were expecting a shipment of HVAC equipment sometime today.  We cleared off the north wall and moved the plastic shelving unit there.  We gathered up various tools and supplies and organized them on the shelves.  Other things got put other places and eventually we had enough space for boxes in the back and pipe on the floor.

While we were working on the garage the landscaping crew showed up but not Steve.  They worked all day trying to finish up the job based on Steve’s verbal directions but they either got bad directions, did not understand what they were told, did not understand what needed to be done, or just did not care about the fine/finishing details absent Steve’s direct supervision.

Our next task was to pull a 50′ 12-2+g NM cable into the attic from the sub-panel location and across to the west side of the attic where I coiled it up and left it for now.  This cable will eventually provide a 240V/20A circuit for the new library air-conditioner condenser/compressor on the west end of the garage.  I will complete the installation of the outside disconnect and connection to the condenser once Darryll sets it in place and gives me the go-ahead.

I turned off the main breaker in the sub-panel and started pulling five NM cables into the panel box and making the connections.  I was part way into this work when a tractor-trailer showed up from Behler-Young with our HVAC equipment and parts.  (B-Y is the largest HVAC distributor in the State of Michigan.)  I helped Bill unload the iron pipe and the smaller and/or lighter boxes.  He unloaded the palleted equipment and heavy parts boxes using the lift gate and a hand truck.  It was a good thing we had cleaned and organized the garage when we did as the boxes of stuff took up the whole east half of the north wall.

By the time Bill left it was noon so we stopped working and had lunch.  After lunch I finished connecting the new circuits in the sub-panel, put the cover back on, and turned on the main breaker.  I tested the west and northwest outlets and discovered that the three duplex outlets closest to the back door had an open ground.  Hummm; I did not see that coming.

I tested all four of the outlets closest to the door and all of them had open grounds.  I went to the next pair of duplex outlets and found that the ones closest to the door also had an open ground but the other two tested correctly.  I turned off the circuit breaker for that circuit and took the cover plate off of the pair of duplex outlets closest to the door.  The outlets were grounded but there was only one cable feeding that box so the problem was upstream somewhere.

The box with one good and one bad duplex outlet was the likely spot.  I took the cover plate off and pulled the outlets out.  The incoming power went to one pair, the hot and neutral were bridged to the other pair, and a cable ran out from the second pair, but the grounds were not bridged through.  Really?  Yeah, really.  So I fixed it, turned the circuit breaker back on, tested various outlets, and everything was now OK.

I had assumed that that power from the attic went to the outlet box closest to the door and then ran around to the southwest corner of the garage but in fact it did not go to either of these first two outlet boxes.  Old houses often have strange wiring configurations.  We have one circuit breaker in the sub-panel that has a wire attached to it and the cable runs up into the attic but we have been unable to find what, if anything, it powers.  I also found a cable in the garage attic yesterday that runs through the attic above the library and disappears into the house attic but is not connected to anything on the garage end.  The cable is not energized and its location suggests that it may have been powered from the sub-panel at one time, but what it might have powered is a mystery at present.

Since the HVAC equipment arrived today as promised I figured Darryll would be here tomorrow to start on the installation.  We still had a lot of stuff in the garage that was potentially in his way so I moved most of it into our temporary storage pod.  It was 3:30 PM and I had apparently accomplished everything that needed to be done today.  That was an odd feeling but with nothing else to do, construction wise, I sat down and had a cup of tea.

Steve (Village Landscape Development) called to make sure it was OK to come by in the evening to inspect the day’s work and, hopefully, collect the final payment.  Linda and I did a walk-around and found so many little details that were unfinished or wrong that I called Steve back and suggested that coming this evening would be a waste of time as he would just have to come back tomorrow with a crew to fix/finish the job correctly.  He agreed.

No longer content to take someone’s word, we found our auto-level, elevation pole, and 100 foot tape measure.  (An auto-level is not a typical homeowner tool, but we have one, so I guess we are not typical homeowners.)  I set the auto-level up on the basement walkout deck and leveled it.  We pulled the tape straight out from the center of the deck 70 feet and took elevation measurements every five feet.  The grade for the first 45 feet was not clearly downhill like it was supposed to be.  At best it was level and rose slightly at two points.  There was an obvious high spot to the left headed up the slope, but I did not even bother taking a reading on that.  I really wanted the landscaping done before the HVAC work started but it looks like there will be at least a little overlap.  That means I will have to split my time and attention.  I spent a lot of my working life “multi-tasking” and now find it tiresome.  I prefer to focus on one thing at a time when possible.

 

2104/07/12 (S) Natural Gas

Leave a reply

You might think that this would be a reference to the natural by-product of having breakfast with our ham radio friends in South Lyon this morning at the Senate Coney Island, but that is not the case.  We had a 10:30 AM appointment at the house this morning with Darryll Mech of DCM Heating and Cooling to finalize the work that needs to be done to get the house ready for conversion to natural gas.  The natural gas contractor for Consumer’s Energy (Roese Construction) started installing the main lines in our area a couple of weeks ago and they expect to have the project completed by September 26 (of this year).  That means we will have natural gas to the house sometime between now and then and we need to have everything as ready as we can before they hang the meter so the final conversion will be minimal and quick once the natural gas is turned on.

The work at our house breaks down into three pieces.  The first piece is running black pipe on the outside of the house from the southeast corner down the east side, across the back, under the upper and lower decks, along the back of the garage, and up the west side of the garage.  The gas meter will be installed at the southeast corner of the house where the propane currently enters the house.  The existing house piping will be used to supply natural gas to the house furnace, kitchen range, and outside grill connector.  The whole house generator is by the southwest corner of the garage and is currently on its own propane tank.  After the natural gas is hooked up everything needs to be on a single natural gas service/meter.

As the gas pipe runs along the back side of the garage there will be a T to supply gas into the garage.  That has to do with the second piece of the work.  We are having a ceiling mounted garage heater installed and a small furnace/air-conditioner for the library.  The HVAC unit will allow us to heat the library in the winter without cycling the main hot-water baseboard heating system, which is at the end of a long run through unheated attic space and is not particularly efficient or effective.  More importantly, it will allow us to control the humidity on humid summer days (it’s a library, after all, so it contains a lot of books and other humidity sensitive paper materials).  As part of that work we need to remove a propane space heater that is mounted in the wall abutting the garage and cap the line.  We also need to remove a window mount air-conditioner in that same wall.  Yes, that’s right, the current A-C for that room exhausts into the garage.

The third piece of the puzzle will be disconnecting the propane and converting the appliances that currently run on propane; the kitchen range, the main furnace, and the generator.  We will have Darryll take care of disconnecting the propane from the house and connecting the natural gas to the existing house piping and start up the two new furnaces once the gas is available.  We will then have TOMTEK convert the main furnace since they already service it for us.  Depending on timing we may be without our main furnace and domestic hot water until TOMTEK can complete their work.  I may convert the range, have Darryll do it, or have TOMTEK do it.  Regardless of who does the conversion I will need to get the conversion kit.  Bratcher Electric will connect the gas line and convert the whole house generator and do the annual service at the same time.

While Bratcher Electric is here we are going to have them run a 100 Amp, 4-wire cable from the outlet of the transfer switch in the southwest corner of the garage to the panel in the northeast corner of the garage.  The existing setup has the 200 A main panel in the basement of the house with a 60 A / 240 V breaker supplying the cable that feeds the sub-panel in the garage.  That means the power to the sub-panel goes from the garage all the way to the house and then all the back to the garage.  That’s a lot of unnecessary forth and back.  In part because of that, and in part because of the electrical needs of the new garage furnace and library HVAC unit, I am going to replace the sub-panel in the garage with a 100 Amp main breaker panel in advance of all of this work.

The current sub-panel is a General Electric but the main house panel is a Square D Homeline.  Lowe’s and Home Depot carry both the Homeline and QO product lines from Square D, and Home Depot also carries GE and Siemens.  If I installed a GE main panel in the garage I could potentially reuse the existing breakers and save a little money.  On the other hand, they have been in an unconditioned space for who knows how long, and they are not physically compatible with the Homeline breakers.  Indeed, the four different products are not generally interchangeable.  But the main consideration is selection and availability, and the Square D products win on those criteria.

Once the new furnaces are installed we will still have some work to do.  We will have to repair the walls in the library, insulate the hot air duct in the garage (although Darryll may take care of that), and enclose the library HVAC unit.  Because the library HVAC unit will be installed in the northeast corner of the garage it has to be in its own little sealed room to prevent automotive engine exhaust or other noxious fumes in the garage from being drawn in to the conditioned air or explosive fumes, such as gasoline vapor, from being drawn into the combustion chamber.  The furnace will have its own air intake and exhaust tubes.  The garage heater uses a sealed combustion chamber with a special concentric intake and exhaust tube, so it does not have to be enclosed.

Darryll indicated he could start the last week of July and would need about a week to do all of his initial work.  We have company coming the 20th through the 23rd, so we have the upcoming week to prep (clean out) the garage and library for Darryll.  This is the kind of situation that could give us gas if we weren’t used to it and enjoy it.  There’s nothing like a construction project to get you up and moving first thing in the morning and keep you up late at night.
