Intertherm gas furnace to Propane

Hello every one first off I would like to say thank you in advance for any answers and help I receive. I have a Intertherm gas furnace that I would like to convert to propane "LP" Im almost 100% sure that I can convert it since it gives orifice sizes for LP on the unit.

Intertherm 60,000 btu output
Model # MGH-075ABWN-06
Serial # MGH8903-01869

Thanks again any help is appreciated.

Not familiar with the gas valve in it, but some models have a screw to turn (old colemans) or a spring to be added to press down the valve to be fully open, along with changing the orfices, the pilot orifice also needs to be changed. I'd consider a pro to set it up for you if you don't have the install manual. Sooting and other problems can occur if it's isn't properly set for pressures........Edit, the old coleman valves you actually switched ends of the assy screw for either. Some appliances come with the turning of the screw. Bottom line to all out there, don't play with gas to save a few bucks, please.

The gas valve on that furnace may be one which requires only the removal of a cap/plug, turning it over & re-installing it. Most moble home furnaces are made that way. You will have to change the orifice.
