Garage Heater

 I installed a garage heater this weekend.  I have had it for about a year and finally got around to installing it.  I think it will be pretty nice to heat up the garage to work out there.  We aren't going to heat it all the time, that would be pretty wasteful, just when we are out there.

The first issue I ran into was that the heater is a little more narrow then the 24 inch rafters in the ceiling.  so I just screwed a 2x4 into it and screwed into that.

I used these thread hanging screws that worked OK, probably should have just used angle iron like everyone else does.  Trying to muscle the heater onto the posts was a challenge.  I wish I would have had a drywall lift.  You can see the rods were able to move around a bit which allowed it to work.  The fit was quite tight.

It feels very secure and doesn't move around at all, so I am pretty confident in the threaded rods.  Once it was up, I had to figure out where the exhaust would go.  I used a carpentry square to figure out where to make the hole in the wall.

Always the scariest part, putting a hole in an exterior wall.  I used a rotozip tool, which made quick work of making the hole in the drywall.  I used an ocsillating tool on the vinyl outside, since I had a block with j-channel built in.  Getting the siding off so I could slide the j-channel in was a challenge in the cool weather.

I originally just had the exhaust blowing out pretty close to the soffit.  But thought better of it and added another 19 inches of length, I don't think it will hurt anything there.  It is supposed to be 4 feet out, but that would be really far out!  Since we aren't running it all the time, I am OK with where it is at.

Here it is running.  I am working on making a thermostat, and I need to put in an outlet to plug it into.  I am also dealing with a small gas leak.  I had a bigger leak, but it turned out that I needed to use pipe dope instead of tape on the connector hose, they need to seat all the way into tube.  I think the new little leak is at the test port, I tested the pressure 7.8 inches into the value and 4 inches going into the manifold.
