The Lennox 18L11 is a Natural Gas to Propane conversion kit is used to change the natural gas furnace to a propane furnace for high-altitude applications. This particular kit is useful where natural gas is unavailable, but propane is an bettersubstitute for the same. The conversion process entails the exchange of major parts of the furnace. This kit may contain a new propane gas regulator that determines the amount of propane gas that gets into the furnace.
