SOURCE: Propane fireplace insert won't light

Gas apliances have safety features built into them so you don't blow yourself up. The pilot heats a thermocoupler which tells the gas valve there is a flame, open the main gas to the burner. If you can see the flame area of the pilot look for a round post about 3/16 inch in diamiter. This should be directly in the flame, if not bend the bracket so it is in one side of the pilot flame. The thermocouple is attached to a mounting bracket. This will be held in place by a 1/4 inch hex screw. remove the screw and the capilary tube leading to the gas control valve. Before you do anything, close the main gas supply to the fireplace and disconnect the power to the fan. You may need to semi dismantle the fireplace to get the thermocouple. The gas valve end is a brass 1/4 pipe thread plug. Turn the outer nut and remove without twisting the tube. Reverse this order to install a new one. Besure not to twist the capilary tube, tighten brass nut 1/4 turn past hand tight. Your better heating supply house will have these in stock. Restarting the pilot will take a few tries because the gas was off. Your gas suplier would charge about $75 to fix this. if you don't have the proper tools and it dosen't look pretty stright forward don't do it. You could get dead.

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.

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.

I am just guessing but it may be set to low. The rush of air when it extinguishes could be blowing it out.

Good Luck,

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!

Pilot light won't light on ventless fireplace


Ventless Gas logs, Vanguard, VS30PR. Propane gas
Pilot light stays lit various times, sometimes for several days then other times for a few minutes. Lights best when temp outside is below freezing. Pilot flame appears to receive too much air. How do you adjust the pilot flame? Is this done using two screws marked A & E? Do you have suggestions?
Thanks,
Ed

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. :-)

Remove the small copper colores tubing going from the gas valve to the pilot assembly. Take it to a good hardware store that sells heaters and ask them for a new one.It is called a thermocouple.

WE can get the pilot light lit but it will not stay on


You will need to check the pressure regulator for the gas.
It sounds like the gas pressure is to low to keep the pilot lit.
