Abstract
An exhaust vent adapter is provided for use in a heating system having a plurality of heating units, which allows all heating units to discharge combustion gases through a single exhaust opening. The adapter comprises a body with a plurality of discrete chambers formed therein, each chamber communicating with a separate heating unit. The body of the adapter has a single exhaust opening formed therein, through which each chamber is independently connected to a separate exhaust vent pipe. The vent pipes leading from plurality of the chambers are concentrically arranged, and may be extended through a single opening in either the wall or ceiling of a building in which the heating units are installed. In a preferred embodiment, the body of the adapter has a single divider secured therein, which defines two chambers and segregates the combustion gases from a pair of heating units.
