Vent Extension Kit for 33.3" Multipoise Non-Condensing Furnaces

FEATURES

This vent extension kit is used for the Category I venting of gas furnaces. The pipe is constructed of aluminized steel and offers greater corrosion resistance than conventional single wall galvanized steel vent pipe.

It is not a substitute for Type B vent or Type B vent connectors used outside of the furnace casing.

The pipe is sized for downflow and horizontal applications where the vent pipe passes through the casing. It may also be used in any application where a 4-Iinch single pipe vent connector is permitted to be used a vent connector. It can also be used to replace the vent connector that passes through the blower compartment on older style downflow/horizontal furnaces. The vent pipe may be cut, or additional pieces added to fit other applications.
