What size orifice is used on a LH680005 pilot assembly for LP Gas. This is on a carrier 58GS furnace.

you need to divide the total BTU by the number of burners minus the percentage for specific gravity and altitude.

Best left for a professional since you also need to convert your gas valve and have a low pressure switch in line to your pressure switch for your inducer motor.

This comes in a complete kit from Carrier

but the orifice size is .011 not .017
