I have a mobile home furnace with a 7200ercs Robertshaw-Grayson gas valve that I need to convert from using natural gas to LP. Is there a procedure for doing this?

Thanks.

Call your local HVAC supply house. Give them the Model/Serial # of the furnace and gas valve. Not all units are convertable from Nat gas to LP. Some gas valves have a kit to convert. You also have to change the orfice in the pilot. Please do not just hook of the new gas and start it. You could create a Delayed detinition and hurt yourself. Call the Pro's on this one.

Thank you David. You are right in your statements. I'm assuming that that this one is convertible as it has a regulator pressure converter valve that reads "Nat. gas on one end and LP on the other". I could not find any orifice, however, that could be removed and replaced with one of different size.
