Question about Procom (177653) Utility Heater
I have a ProCom blueflame heater. There is a dial on top to operate it. The lighting instructions say to move the knob to "pilot", hold it in the depressed position, light the pilot and then you are supposed to be able to let up on the knob and the pilot stays lit and you can move it to the heating positions (low, med or high).
The first problem is getting the pilot to light. When a tank is initially connected, I have to hold the knob in the depressed position for perhaps 10 or 15 minutes to even have the pilot light up at all. Then, once it does light (with the knob continuing to be depressed), I have to hold the knob down for it to stay lit. If I let go, it immediately goes out and I have to repeat the process. If I hold the knob down, the pilot will stay on, but goes out immediately upon releasing the knob.
This continues again for 10 to 15 minutes. I have to continuously depress the knob and eventually 'get lucky' where I'll release the knob and the pilot light will stay on after which time, the heater appears to work flawlessly.
What causes the initial delay in even being able to light the pilot light? Is it just air in the line? Can anything be done? Then, once it lights (with the knob depressed), why doesn't it stay on immediately. Do I have a leak in the system? Bad thermocouple? Other issue?
This is only a problem on the initial startup. Once it's been running, I can move it back to the pilot position and the pilot will burn continuously as it should. Trying to understand what the problem could be so that I don't have to sit and depress the knob for 30 minutes every time I go to startup the heater. Seems it should work instantly or nearly instantly.
The main heater will not light unless the pilot light stays on and I can't move to low, med or high settings unless I release the knob from it's depressed pilot lighting position which I can't do until I've monkeyed with holding it down, releasing, relighting, etc... for a considerable amount of time.
Is there something I can try to do that might fix this problem or at least troubleshoot where the issue might be?
The igniter want light

Holding the button down enables gas to go to the pilot. When it lights you will see the flame touching two rod like devices. The small one is the igniter. The second one is a thermocouple. A thermocouple is a bimetalic device (2 disimilar metals) that when heated produce a small curren, this current in turns keeps the valve open for the gas to flow when you let go of the button. This is a safety feature. If the flame goes out on the pilot the thermocouiple cools and closed the valve shutting off the gas so you don't go boom! It sounds like the thermocouiple is bad or missaligned. If it is missaligned it will take longer to get hot enough to hold the valve open. Another thought would be the flame is not shooting out far enough (not enough gas pressure, clogged oriface on pilot(previous writer, leak but you get the idea. In my manual it had a picture of how the flame should look hitting the thermocouple. Good luck. My problem is I assumed that the regulator on my construction heater was the correct size. Maybe not. I have not had any luck getting the pilot to light at all. I hope I have not damaged the internal regulator.

The problem with the ProCom is the inlet pressure valve. The spring is too light, so when you turn the propane or gas valve on the rush of gas closes the valve and it won't release. To undo the issue, first you have to release the pressure against the valve. To do that you must break the line open with the gas turned off so the gas will escape allowing the piston to open. Tap lightly on the pipe going into the heater to guarentee it opens. Reconnect the pipes, inflate the lines with gas with shut-off closed.
Slowly crack open the shut-off valve slightly and start the lighting process, holding down the pilot button and striking the igniter. When the pilot starts, continue to hold down the pilot button down and slowly complete opening the shut-off valve. The pilot light should now stay on.
To possibly prevent this, shutoff the gas prior to extinguishing the pilot light and restart as described. If re-connecting propane, close the shut-off valve prior to turning the tank on, then starting as above.

I have just purchased a procom ventless heater. The pilot would light after going thru normal start up. Returned new heater and received replacement. It won't start either. I replaced a ceramic with open flame.
Tried calling 877 number for help. Auto system said they would call back in 21 minutes. It's been over three hours and still no response
