I have a ML300EBC Procom. I hooked it up and everything electrical worked but there seems to be no gas(propane) getting to the pilot. There is no smell, it sparks but nothing. Yes tank is just filled and turned on. Could the internal regulator be damaged. It is brand new never used unit. Help!

I would trace gas line out and determine were you are getting gas and where it is not. With the gas on I would carefully loosen union or flex fitting going to gas valve.If you have gas there then retighten union and go to fitting on pilot line and check it.You should be able to get gas there by depressing pilot light button.If you have gas there then go to pilot assembly and remove it from gas valve and burner. Remove pilot orifice and carefully clean and blow thru pilot line to make sure it is not obstructed. If you cannot get any gas thru gas valve then shut off gas before valve and remove inlet line. There should be a fine mesh steel screen there. Make sure it is clean.If you are getting gas to gas valve but not thru it then you probably need to replace gas valve. Thank you
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.
there may be an adjustment screw for pilot height. you'll have to look at the valve. a pilot should have an inner cone of greenish blue color and the surrounding flame should be a deep blue no yellow or orange tips. the pilot burns pure fuel no air. the main valve does mix air with the gas in order to burn.
