I installed a ProCom ML300TBA propane heater in my greenhouse. I am using a 7gal tank W/ inline regulator(regulator does not say what pressures it is preset to opererate at) and a 12" hose to bring fuel to the heater. The pilot lights just fine and keeps burning properly intil I turn the dial clockwise to turn up he heat. At this point,instead of the main burner lighting,I hear a "click" and the pilot goes out. Any Ideas!!
PS: I looked for a manual on line, But could not find one or a company site for Procom.
i have pro com 300 set up for natural gas and pilot light will not stay lit after the themostat cycles---plenty of ventilation but i did add blower unit made for this heater,i have pro com 300 set up for natural gas and pilot light will not stay lit after the themostat cycles---plenty of ventilation but i did add blower unit made for this heater,
I have a Pro-Com Blue flam heater, It work fine for about 5 mins and them the pilot light and the flam will all go off... It makes a clicking nose when it goes off it will will not stay on for no more them 4 - 5 mins at a time even when you first turn it on. Im not sure what the problem is??...........

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.
I have the manual for this heater and it states that a minimum tank size of 100lbs (25gal) and at least 1/2" piping is required to deliver the proper volume of gas to this heater.
Just a hunch, but most propane have left handed threads. Meaning they turn the opposite from everything else. Its possible you are turning the gas off by mistake.

I wold check gas pressure to your heater. If it's natural gas it should be about 4 ounces at gas valve. If it's propane/L.P. it shoul be about 7 ounces. If you have a gauge that you can check the pressure with there is usually a port on gas valve that is plugged and usually stamped test. Hope this helps you, Thanks
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
you need to find a place that makes your type of heater and they will have a change over kit all it is different orfices and jetcovers for each gas jet from your heater its self explanitory once you see the parts,sometimes there are different gas comp. that if you use there service they will change you over at no or little cost. hope this helps
Propane exist in a liquid state when it is under pressure in a propane cylinder. When the valve on the propane cylinder the pressure on the liquid is reduced and the propane reverts back to gas state.
Also, regarding the tank you need....
the owners manual probably states what size you will need but, with most heater like the one you have it will require a 100 lb tank (approximately 25 gallons). You will also need an inline regulator set to 11" to 14" of water column between the tank and the heater.
Not enough information to solve the problem correctly but I'll take a guess at it......
This heater requires a 100lb propane tank (approx. 25gal) with 1/2" or larger piping to deliver the correct volume of gas to the heater. If you are using a smaller tank (like a 10gal) or the piping is not the correct size you will not get enough gas to the heater to light the pilot. Also you should have a regulator set at 11" to 14" of water column installed between the tank and the heater. If the tank is connected directly to the heater you may have damaged the internal regulator in the heater.
I have a similar problem. But, I want to convert it to propane. I have a 5 burner vent free modelMN300HPA. If your are handy. I would consider shipping you the parts inside mine to install in yours. These parts are very simple to remove after removing the access panels. I have taken mine out already. Called procom then to no less find out the propane parts needed are not sold by them. I think only the injectors (5) the main valve (regulator) and the pilot are the only things need to change. When taking out the pilot this is easly done, By removing the nut on the supply line. And then bending back the retaining tabs to then slide back the pilot then it comes out of the assembly bracket. Injectors are simply removed. Regulator located at the bottom is a simple remove. The only other item that might be questionable would be the valve that selects the amount of burners you would like to operate. And I would think this would be the same and not need removing. Let me know if I can help. I would like to get mine converted to propane. Thanks Tom
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.
