    It takes more than just changing the orfices

    Yes I know that the spring in the gas valve needs to be changed and that the gas pressures need to be adjusted to 10.5" WC. But I don't know where to find a conversion kit

    ICP and Heil use the same part number orifices. The question is which one is for LP and can the furnace be converted to LP safetly. As you are aware the LP orifice will be a smaller drill bit number size than the one fromnatural gas.Good hunting.

    On most lp furnaces the orifice size for LP is a 55. And I can't find anywhere that I can buy the conversion kit & yes this furnace is safe to use with LP. Does anyone know another place other than sears that I could go to order the conversion kit??

    Your local HVAC company/tech, should be able to get and install one, most hvac supply houses won`t sell to anyone that's not trained and a qualified hvac machanic or contractor,, lots of liability involved when dealing with gas appliances
