SOURCE: Gas fireplace pilot flame won't stay lit.

Hi , you can try and pull the panel on the bottom of fireplace out and check the adapter in fireplace. Sometimes they go bad. When you open in also check to see if there is an adapter plugged in and a option to use the battery operated function. If this goes bad the pilot will not stay lit.

Thanks for your question,
your problem is either impingement on your log set, or a product of incomplete combustion, if you notice soot on your logs, then you will need to take them out, clean them, and reinstall them as to not have the flame touching them, you will need to clean the burners as well, make sure nothing is laying across the burners, as this too will cause sooting, as far as incomplete combustion, was this model a natural gas converted to propane or the other way around ? if so who ever converted it, did they adjust the gas valve according to specs? improper adjustment will cause sooting or hooking up a natural gas unit to propane will do this too, I will recommend using (Rutland White Off) to remove any soot from your glass, it works fantastic for this ! any ace hardware will carry it, please do not use windex or any other cleaner on the glass as it will more than likely leave a rainbow affect on your glass once the glass heats up, hope this was helpful to ya, please rate this solution, thanks agai

SOURCE: I HAVE A DESA LP VENTLESS FIREPLACE AND THE PILOT

the heater makes use of a millivolt generator which generates a small dc voltage (500-750mv) that is applied to the pilot valve of your main gas valve. when you light your pilot, the flame bathes the generator with a flame. after a delay you release the pilot button. if the generator is working, the pilot valve will stay lit. if the generator is not working the flame will go out as soon as you release the pilot button. change the generator.

OUR FIREPLACE WILL NOT IGNITE. THE PILOT IS LIT. WE HAVE HAD ALWAYS HAD TROUBLE IN THE PAST BUT IT WOULD EVENTUALLY LIGHT. NOW, AFTER MORE THAN A DOZEN TRIES, IT WILL NOT.


The safety feature for your fireplace is probably a millivolt pilot generator. It serves 2 functions. It holds open the pilot safety magnet AND operates the solenoid on the millivolt gas valve. The pilot generator is weak. It will hold open the safety but not work the operator selenoid on the gas valve. Replace it. And party on!

Sometimes when you turn a gas heater off for some time, if the source tank has been turned off, the line will bleed the propane and the line will contain mostly air. This is especially true if the supply line is long. In order to light the pilot, you will have to hold the pilot lighting button down for a while (a full minute or longer, depending on the size and length of the supply line) before pure propane arrives at the pilot light jet. You should keep a lighted lighter at the jet so that when the gas arrives, the lighter will light it. After the pilot lights, you will have to keep the button pressed long enough for the thermocouple to get hot enough to set the pilot to stay on. When it is hot enough, you should be able to release the pressed lighting button and the pilot should stay on. If it does, you should be able to light the heater. If the pilot jet never lights, gas is not getting to the regulator. If the pilot will not stay lit after a period of time waiting for it to heat the thermocouple, the thermocouple or the regulator may be bad and need replacement. :-)

Pilot on logs won't stay lit


Hold pilot button longer. if this doesn't work your Thermopile has gone bad and will not generate enough Millivolts to keep gas valve pilot open. A new thermopile will generate 750 millivolts. It cost less than $20 dollars but is difficult to replace. You should call a certified technician. They will charge you about $100.00

Pilot light will stay lit as long as i hold down the knob, but when knob released, light goes out....... i have a wall mount model# GWRN30t


Normally when you release the knob it work the same as a two way switch ,which mean gas will stop flowing through the small pilot channel and will flow to large channel where it will continue to burn.
In your case, you have to strip down the regulator switch and look where the gas passage is glogged.
