I hooked up the a high pressure regulator and it won't light
I hooked up a high pressure regulator by mistake and the pilot did not light. When I discovered my mistake I hooked up the correct regulator and it still did not light. Did I damage the internal regulator? If so what is the part # and cost and where do I get one? Thanks

The pilot flame should be a firm blue color impinging directly on the thermocouple enough to turn it red hot after a few minutes. Generally, the pilot flame need not go past the thermocouple more than a 1/4 - 3/8" and should not be a lazy yellow color. As far as adjustment to the pilot flame, it depends on the heater brand you have. Look at the gas control for a small adjustment screw near where the silver pilot tubing connects from it (it connects to the pilot assembly on the other end). Adjusting it counter-clockwise will lower the flame size, if necessary. If the pilot has a lazy yellow flame, the pilot orifice may just be dirty. With the pilot flame off, use a can of compressed air (with attached straw) to blow out any debris/dust from inside the pilot assemble where the orifice is. Good luck.
Not familiar with these models, but it sounds to me like it could be a gas pressure problem...? Is there a regulator - sometimes they fail. Are any other appliances hooked into the same gas line? If so, how well are they functioning?
The regulator on the heater probably is not but is probably a device to prevent the heater being used unless the gas pressure is high enough and also serves to prevent air entering the gas line and also serves to arrest flashbacks.
The standard propane low pressure regulator is 14" water gauge but the heater might need a high pressure regulator. The best way to decide which type of high pressure regulator to use, because there are several, is to use an adjustable regulator.
After installing the adjustable regulator the pressure is increased until gas can be heard to be flowing and the heater lit. The regulator should then be adjusted to produce a clean flame of the correct length and then the regulator adjustment locknut should be tightened.
If the heater is to be used indoors it is important to ensure there is plenty of ventilation and the emissions are checked by a gas engineer.
For (fire) safety, there is usually a thermostat that will turn off the gas if pilot light goes out.
So when you try to light the pilot you will have keep press & hold the pilot gas supply for at least 10 sec until the thermostat is heated up. Then only when the pilot light stays on continually, can you turn on the burner.
Forget about changing to a High pressure regulator!
The Tstat has a capillary that looks like a thermocouple but it isn't, its a bulb with liquid that expands and contracts based on temperature. A pilot can go out due to a high limit switch being week or getting to hot and that can be shaped like a thermostat capillary or can be simply a disc with a button if even there is a high limit on your stove. There likely isnt. So see the next suggestion.
I suggest lighting the pilot, turning on the main burners while watching the pilot. If the pilot shrinks in size, then check your gas pressures before and after turning it on and seeing if there is a wide variation. I would suggest the pilot is dirty or the pressure regulator is faulty.
My manual shows three possibilities: 1) Insufficient fresh air available for combustion, so ODS kicks off gas flow 2) Low gas line pressure (should be between 11 and 14") or 3) ODS/Pilot is partially clogged. Toll free number for ProCom is 877-886-5989.
If it were the gas regulator, existing flames would go down as more burners are turned on.
There are set screws on the pilot fittings that come out of the manifold, you could try turning those Counter-clockwise to turn the pilots up. (Don't loosen them all the way, they will fall out!) If that doesn't work chances are the pilot stems will have to be replaced to get a higher pilot flame.
