I have a new Model 3003622 wall furnace with propane conversion in our cabin. It worked well for the first five weekends, but now it lights up after firing up the pilot, burns strong for 10-15 seconds, begins fluttering, and goes dead after 30-60 seconds, pilot and all. The pilot porthole door gasket flaked off early on. Any thoughts?

The low voltage wiring and the thermostat has noting to do with the pilot function of the wall furnace, check to see if when you have the pilot lit manually, while holding the button in does the flame impinge on the thermocouple and does the flame try to wrap around the thermocouple? if not the thermocouple and pilot flame need to be adjusted so that it impinges on the TC, if it does have a good flame impingment, then you probably have a bad TC from the factory, call them and have them send you a new one if still under warrenty.

Hi,
The problem is with the thermocouple.... this is the metal thing that the pilot flame hits when it is burning....if the flame is not hitting it then it does not get hot enough...

make sure the flame is hitting it....if not then adjust the hood over the flame to get it on the thermocouple...

If it is hitting it then replace the thermocouple....for that heater though the thermo is probably and OEM part and may have to be bought from the manufacturer...

I'm having the same exact problem... At first we thought was the vent... but the way the flames goes out... it seems that there is "not enough oxygen" more than "blown out by the wind"... right after both main & pilot goes out, I can't even light any external flame inside the chamber... and it doesn't feel like the outside cold air coming in... it just feel like there is some sort of gas in the chamber that's so strong, it prevents flame... and the only thing I can think of is that it doesn't have enough oxygen, but too much natural gas, and flame can't sustain.

Try jumping out the thermostat (red and white wires) that run to the thermostat these tell the heater to come on. Jump them together if you have heat it is the thermostat, if no heat it is the furnace. Should it be the furnace I would first check the thermocouple or some manufacturers call it a flame generator. Clean this with steel wool and position it in the top center area of the flame as this is the hottest part of the flame. Good luck

is it a standing pilot light?
