Heater Test

[CDACamper]

I'm trying to test the heater in 2001 SM. Turning on the switch at thermostat and when turning up the thermostat the fan clicks on but no heat. Does this valve need to be opened at the propane tank? Odd to me that there is the word "Vapor" under the valve and I'm nervous about what it's for

Here is a photo of the propane tank with the valve circled in red.

Yes that valve needs to be open. Then close it while travelljng. It may take a while for the heater to light up after the valve is open.

As stated before that’s the propane shut off valve. It needs to be turned on. Also as stated before it may take awhile to light after the valve is on. Normal devices run off propane vapor not liquid. I believe vehicles, forklifts etc run off liquid propane that’s why it’s labeled that way.

You may need to purge the supply line by starting it four or five times in a row before it will light. This is pretty normal when they have sat for a long period of time.

They start better if the tank is full...........
