How to convert a Coleman gas valve? What’s the cost of a gas valve conversion?

The new S1-025-43267-000 Coleman Gas Valve is designed to replace most of the previous models. Convertible furnace gas valve is easy to replace, and compatible on most Coleman furnaces with electrical Ignition.

How does Coleman Gas Valve work in a furnace?

The gas valves are controlled by electromagnets and operated by two valves. The primary valve allows passage of the gas to the pilot light and the main valve supplies the natural gas to the burner trays. Generally, a transformer supplies power to the main valve using a thermopile that keeps the primary safety valve open and another thermopile that gives a passage from the second valve to the burner through a long tube.

How to convert natural gas to propane in a gas valve?

In the new series of Coleman gas valves, it is easy to convert the bolts in the orifices to convert from natural gas to propane. The  step-by-step process is here:

• Power off the gas valve and the unit.
• Take out the gas valve after disconnecting it.
• Locate the two orifices for two valves and with the right-sized wrench disassemble them.
• Install the new orifices and connect them with the unit.
