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).

Hi Robert,Make sure you have gas in the tank ,first turn on your propane tank, the knob is at the top of the tank with a small arrow showing you the way to turn it on.Then on the heater you should see a red knob with the words-pilot-on-off.Turn to pilot then light it,you may have to push the red knob in-wards at the same time as you light it to let the gas come in.Now if you see a small flame stop pushing in the red knob and let it go slowly.the small flame should stay lit, now turn the knob to the -on-position and set your thermostat. If this did not help you please have a heater repair person help you to see if you may have a problem. remember you are dealing with gas this is dangerous.
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, check the gas valve and make sure the valve in all the way to "on" not "pilot".After shutting to off for the winter, and not turning the valve all the way on start up could be it. If that is ok, check/replace the pilot generator next to the pilot lite. One question. Does the pilot go out soon after calling for heat? Next, if you have it on "spa" or "pool" on the temperature adjusting module, try the other setting. eg. If it is on "pool", switch the knob to "spa" and adjust the temperature.
If your Laars will not stay lit then the pilot generator is faulty. That
is the small brass and copper piped connection near the pilot flame. It
must produce 250minivolts in order to open the main gas valve and keep
the gas running into the pilot burner..

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
One possible reason could be a bad thermocouple. This is a rod shaped device that is close to the flame. It's function is to turn off the gas if the pilot light goes out. Heat from the flame operates the thermocouple. When the flame goes out the thermocouple cools off and shuts off the gas. When one goes bad it will not let you light the pilot. Here's a picture of what one looks like. There's a bracket that holds it in place.
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.
change the gas valve, if the thermocoupling works and the piliot stays lit then it has to be the gas valve check to make sure the screen is clear also,, you said it's propane, check to make sure it is all the way turned on, and has the right pressure it might have a bad regulator on it, but will let other things in the house run 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
