Propane. Scary. I did lots of reading and decided on a simple system.
- 20# propane tank mounted on tongue.
- 2 stage regulator with new hoses connecting to tank and to 3/8 coarse thread flare fitting (ask me how I know there are two types of 3/8" flare! - coarse and fine)
- iron underneath trailer
- provide small sump to catch any particulate matter in pipe
- iron up through floor
- use connector to appliance
- 16,000 btu furnace w/ coars thread 3/8" flare
Here are the pieces of the sump to catch any particulate matter.
View underneath the front of the trailer. Up through the floor is the furnace. To the right is towards the tongue.
Don'e use white or pink thread tape on propane systems. The yellow is the only tape to use. Or you can use pipe-dope if that's your thing.
Fitting that goes from iron stub in the floor to the hose to the furnace. Flare on right, regular threads on the left. Don't use dope or tape on flare. Right?
In the top of this photo you can see the iron pipe coming up through the floor and the furnace to the upper left. This yellow flex pipe is what I used to connect one to the other. Is this type of flex hose safe to use in an RV or should I be using something else or a hand-made copper fitting?
Those two wires on the left of this overhead cabinet go to the thermostat.
Inside of thermostat. The directions for the furnace and thermostat are pretty good. Even I could figure'em out. The blue wires from the furnace connect to the screws on the upper left and lower left.
There are several other items like having a fused power source (7.5amp) and ground to the furnace as well as an on-off switch on the pos lead. These were set up and propane hooked up. No smell of leaks and after a test fire it all worked! What did I do wrong? What else to check? I know I need to use soapy water and check all connections. What else? That yellow hose from the iron to furnace has me a bit concerned. I feel like I need to fasten it down, so it doesn't vibrate and fail due to metal fatigue. Any guidance? Thanks!!
