Furnace Gas Conversion


I have a York Furnace that runs on LP. Due to recent LP cost increases, I am considering converting the house to Natural Gas. Most of my appliances are easily converted but I am having trouble determining what, besides the burner orifices, needs to be changed on my furnace to make it work on Natural Gas.

The gas valve in the furnace has a sticker on it that says LP but the part number looks to be exactly what the NG part number is. Do I need to change this?

Any insight would be appreciated.

Yes. There is a different spring for nat gas vs propane. The spring controls the regulator/pressure from the valve. Check with York if the spring is available or whoever makes the valve ie: Honeywell or White Rodgers

Most often those regulators are convertible. You remove the plastic cap and reverse the insert. google the model number and you should find the manual that details the conversion process.
