Question about Heating & Cooling

1 Answer

Emberglow ventless gas logs (set to burn on porpane gas). Pilot lights, but not logs.

I have Emberglow ventless gas logs (set to burn on porpane gas). First I connected them to a propane 20 lb tank and they worked perfectly (for about 2 hrs. until the tank lost pressure). Then I switched to a 100 lb. propane tank -like the manual recommends- and I get the pilot to ligth, but it will not stay on to start the logs. The propane tank is connected with a POL connector and a 1/2 psi regulator (11" CW) to a 5ft. 1/4" hose and a 3/8" connector (commercial kit) to a 1/2" black iron pipe that goes into the house.

Propane appliances usually run on 10-11 inches of water column, this is about 1/2 pound of pressure. If the regulator you have is not rated for delivering gas at that rate, you will need to find one that does. If your regulator is rated for more than the 11 inches, most likely you could have damaged the appliance regulator that came with the heater. Check the propane pressure specified by the heater manufacture against the rated supply of your regulator and see if they match. Make sure the heater is rated for Propane and NOT Natural Gas. Check to see if the gas valve on the appliance is in the operate position and all valves are open. Bleed off the air in the gas line by holding down the pilot switch and keep attempting to light the pilot. It could take you a few minutes. If you hear and smell gas but the unit will still not light, don't chance at getting hurt, call a technician. Look to make sure there are no safety switch that may have triggered off not allowing the gas valve to operate. And make sure there is no obstruction in the heater?s gas valve blocking off the supply of gas. Always exercise caution when it comes to gas and if you are uncomfortable, call a qualified gas technician.

SOURCE: pilot lites; but, as soon as I turn on gas flame

sounds like your thermacouplar is going out and needs replaced. Sometimes these will act like they are working fine , but when the pilot stays on for awhile and later goes out it is a sure sign that it is bad

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. :-)

Lights but turns off in about a minute


It might have a built in thermostat that will light the heater when room temp falls below a certain temp. It should then relight and warm things back up. As long as the pilot stays lit it should work just fine.

Look for a small hole or two in the part the pilot flame comes out of. These may be partly blocked. They allow air to mix with the gas for the pilot.

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

Sounds like a bad pilot sensor called a Thermocouple. It is a copper tube that goes from the gas valve to the pilot assembly. It is the smaller of the two tubes. They are available at better hardware or farm stores. It is best to unscrew it from the gas valve and pilot assembly and bring it with you when you shop for one. It is something any mechanically inclined homeowner can replace.

Try to take pilot assembly apart and clean real good. This will work most of the time. If it does not work for you, you will need to replace the gas valve. It's expensive but I'm about positive that cleaning it will fix it. Gas burns dirty and after a couple seasons a scale builds up that causes this problem. It's pretty common and nothing to worry about after it's cleaned. Good luck.
