you need to get wall switch and wire to this changed as it is impossible to test these for faults as can happen after a few hours of operating (usually to do with the heat of the fire place dso if it has a fan hopefully you are using it it'll keep components cooler in heater and stop things like this happening), but i'm assuming that cable to wall switch runs down side of heater or something and i'm guessing its got hot maybe melted to side of heater and may have damaged wall switch so i would replace both, this has really been the only problem i have had all year with heaters and its due to turning the fan off which you can do in some heaters that arn't entirly designed for heating, if you are heating with a gas heater its important to run fan no matter how noisey it may be and there not that noisey really just turn tv up i'd rather be warm through winter than hear my tv so i'd rather hear a fan than the news, most of the time it sounds more intresting anyway and i have heard of mechanics that have pulled out melted fans from heaters because they were off, i have found cables starting to melt too so its a safety issue too and lastley if your not running fan heat goes up flu waste of money so i think its important and would have maore than half of call outs less as it has been a problem with heaters with turning fan off, i may be wrong but i'm guessing this may be the problem and if you do use fan the cable to wall switch may be down side of heater making contact with a hot surface and melting causing problem i would also do switch aswell as heat could have damaged to as cable would have conducted heat to switch

Hi,
The problem is the nonregulated propane tank....you may have already damaged the gas valve...

The gas pressure coming into the gas valve can be no more then 13"WC or it will not open...
You will need to get a regulator installed in the line from the tank that will allow no more then 13" WC gas pressure to the gas valve...

There are several things that could be causing this problem. Low gas pressure comes to mind, first. Followed by an electronic ignition problem. Which may simply be caused by poor line voltage or a dirty sensor. Amazingly, not using the heater regularly, can do more harm than good. Because, in the long down times, spiders like to go into these heaters and build nests. These nests can really clog things u

As far as the lots of flame on ignition, this is probably a result of delayed ignition, which causes a gas build up.

In addition, if you live in an area that is more than 2000 feet above sea level, the pressure regulator should be adjusted to provide more gas.
