Re-Installing Our Furnace

I just re-installed the furnace today inside the new dinette seat we made, have not connected the electric, gas or ducts yet, it got too late.
Anything I need to watch for? Especially when connecting that gas line.

Looks nice. On your propane connection only use screwed pipe and flared copper for your connections. DO NOT use compression fittings. With the screwed connections, use the yellow Teflon tape of pipe thread sealant rated fro use on gas lines.

After you get the gas connections made, check all of the connections with a soap bubble test with the lines under pressure.

The people that designed these furnaces suck. The rear brace legs that you must screw down are under and behind the duct connection, meaning you screw it in from an almost impossible angle, when it would have been so easy to place that leg between the ducts. The gas connection is in an impossible to reach place with just an access hole barely large enough for the gas line to pass thru. Putting that yellow gas teflon tape on is absolute impossiblity. Lucky for me I had a tube of "Real Tough" thread sealant that says ok to use on all gas lines and stated do not use for Oxygen lines. So I went online to read the spec sheet and found they specifically said it was approved for LP gas line connections. Of course the flare nut is a 15/16 and the biggest wrench I have is a 3/4. I have to use a crescent wrench which gets in there but is very difficult to use, but it will work. ARRRRR. I have only have cut myself 4 or 5 times so far and I still have to route one air duct line around the gas line once I have fully connected the gas line.

It is installed and working from the thermostat, at least the fan part is. when we were done I went into the bedroom and turned the switch to "On" set the temp to full high and waited and waited and waited, nothing happened. I went back with my glasses on and took a look at the thermostat, it was set to 90 degrees and darn if the temp in the room was pegged at 90 degress. Turned the ac in the bedroom on hi and closed the door. Five minutes later the furnace fan clicked on and we had good airflow from all the vents. Turned the switch to "Off" and 3 or 4 min later it shut off. Well I have control of the unit, whenever I get some LP in the tank I can see if the burner lights off.

Bilito, besides your refrigerator your furnace looks the same as mine. I seemed to be having an issue with it this year. The flame when it is running sounds like it is breathing. ( kind of a huffing sound ) I also noticed that the flame is going on and off during it's run time. ( flame shutting down and then coming back on while the motor is running ) I believe it is an overheat problem but I can't get to the flame to see it. I tried taking an air compressor to it but it did not help. I'm going to wait for cooler weather before looking at it again.

The only thing I would be concerned with when hooking up the gas line is over tightening and stripping the threads.. HOWEVER that said I have NEVER managed to get one that thight (I have done it many times on bolts and wheel studs and such but NEVER on those brass gas fittings.... So perhaps you should not worry about that either.

So that leaves bubbles.. Once you have it good and tight, paint it with soap (leak detect) solution and pressureise.. If it bubbles.. Re-tighten.
