Description
The Lennox 77W89 is a conversion kit from natural gas to liquid propane which is suitable for particular Lennox HVAC systems. It has a valve spring and other essentials needed to change your furnace from using natural gas to propane. The gas valve in your furnace controls the amount of gas that is supplied to the burner and this kit replaces the existing spring with a propane spring. Although the dimensions mentioned usually are not given for this type of kit, the advantage of the Lennon is that it will easily change the fuel from natural gas to propane, perhaps a cheaper or easily available fuel in your area.
