Question Nat. gas to LP

I have a chance to get 2-125000 Natural gas furnaces and the ac units for just removing them. What do I need to do to change them to LP. Is it just the gas valves or are there orfices in the burner section? I thank you so much for your help. john

It is the orifice within the gas valve that determines which fuel the furnace is for.
Orifices can be replaced or modified for the correct fuel but it would be usefull to know the model of the furnace and gas valve.

our lp conversion kits come with a new spring and cap for the valve itself, and a set of orifices for the burners. typically honeywell and robertshaw valves are what we see here

Its all in what you have there . Most of the gas valves we run into have a lock out in them for the regulator in it there. Or it comes in the kit with the LP orifices for the burners and pilot light.
