Lennox 18M7901, Masonry Chimney Vent Adapter Kit
Cat # : 18M79
Model/Part # : 18M7901
Product Overview
The masonry chimney vent adapter kit allows venting of 80% efficient furnaces into a tile−lined masonry chimney without the use of a listed metal lining system. The vent adapter assembly introduces dilution air into the flue gases, thus lowering the dew point of the gases and inhibiting the production of condensation. This vent adapter is designed for use with 80AF1UH, ML180UH, EL280UH and SL280UH units installed in upflow air discharge applications. The kit may be used with furnaces fueled by either natural gas or LP/propane gas. Refer to instructions (506774) for a complete listing of the furnaces with which this adapter kit may be used.
