This could be due to insufficient gas pressure. When you turn the knob to get the flames going, observe the pilot light. If it gets smaller, or burns with less intensity, it means you have insufficient gas pressure. If the pilot light gets smaller, the temperature of the thermocouple drops, so the electrical current produced by the thermocouple also drops. The stove interprets this drop in voltage to mean that the oxygen level in the room has dropped (because a drop in oxygen content likewise would cause the pilot light to get smaller).

If you're using a 20lb propane tank (Gas Grill Tank), that may be the problem. Turn off the propane tank at the tank valve and disconnect it from the tank. Wait 5 minutes and reattach the heater hose to the tank. Turn the propane tank valve on very,very slowly until it's all the way open. Try lighting your heater now. If the pilot flame height returned to normal, that was the problem.
FYI - The Thermocouple has nothing to do with the length of the pilot flame. It's a safety feature that stops the gas if the pilot flame goes out for any reason.
Hope that solves your problem. Please let me know.
First, turn off the gas valve for at least 5 min and ventilate the room. Most wall heaters are lit the same as a water heater. Find a red button to push or turn the gas valve knob to the pilot position. While pressing the red button or the gas valve knob, hold a match to light the pilot flame. After it lights continue holding the knob for one or two minutes. If the flame goes out when you release the knob the thermocouple is probably bad.
Hello, The knob needs to be turned so the arrow is pointing at "Pilot". It is the only position you will be able to depress the knob all the way down. Once you light the pilot, keep holding down the knob for 30-60 seconds. When you release the knob, the pilot should stay lit if it's working properly. If not, here's a few things to check. Is the pilot flame blue? Is the flame actually heating the thermocouple end? The thermocouple has to get hot enough to allow the gas to stay on to the pilot. Also look at the tip of the thermocouple. It should be smooth and rounded. If you're pilot flame is a lazy yellow, after time it will burn off the tip of the thermocouple, causing pilot outages. Replacing the thermocouple is usually the easiest fix it and is probably what you will need to do. But if your pilot flame is that lazy yellow, you will also need to clean it by either a tiny broach needle or using canned air (with straw attached). Be careful and because propane is heavier than air, smell low to the floor before lighting it to make sure there is not a gas leak. To be safe, close the gas shut off valve and air out the room before lighting and always follow the manufacturer's lighting instructions printed on the heater. If doing this seems too difficult or scary, then call your local propane co and they will send out a serviceman to fix it for parts and labor. Good luck! Douglas
The thermocoupler is bad.Replace it,or if you can adjust it to where the thermocoupler is in the pilot flame.You know you have to hold the knob down for about 30 seconds or a minute,don`t you?If the flame will not touch the thermocoupler,it will not stay lit.You can cut a piece of copper tubing,or steel tubing to slidde over the old thermocoupler to make contact with the pilot flame,and it will work,if the thermocoupler is not in to bad of shape.
Generally speaking a propane heater stays lite because the pilot stays lite. The pilot flame touches a thermocouple which produces a current which keeps the main valve open. Pilot goes out or you have a bad thermocouple or the pilot is slightly clogged (reduced heat to thermocouple) or maybe the thermocouple is not touching the flame enough. Most times when a propane heater goes out the problem is somewhere in that neighborhood. Thermocouple - pilot. I have always had luck carefully taking those parts off, cleaning, and reassembling, but check the position of the thermocouple first. Looks like a small brass rod which sticks into the flame. This is a safety mechanism to prevent the flame being blown out and leaving the gas on. Good luck
You pilot ignator is plugged.I take a small wire and run it in the hole every year and I also Blow the heaters out real well with air.THis has always worked far me.I need a phone number or email address to Pro Com because i'm having problems with a new one i just bought and I can't find the papework.Could you pleas eif you have this info email it to me
Well, I just went out this morning and worked on the heater after it would not light last night. Turns out that a spider or moth set up camp in the pilot light intake housing and plugged up the two small mixer holes that pull in air for the pilot light. This would explain the 'yellow-flame'. I took a punch awl and some compressed air and cleaned out the hole, then re-installed the cover and knob. Lastly, I turned and depressed the knob and the pilot light ignited almost instantly, stayed on when I let the knob up, and the heater turned on normally after that. Good luck, I hope this helps.
There is a small probe that is heated by the pilot flame. This is called a thermocouple & keeps the gas valve open by generating a small electric current. Most likely the pilot flame is too small, or not heating the thermocouple properly. Either turn the pilot up a bit, or gently bent the thermocouple bracket to put it in the flame a bit more. Do not try to bend the thermocouple itself. If this does not help, a new thermocouple may be needed.
