Description

Single-wall flue reducer, 4" to 3". Steps a vent connector down to match an appliance outlet or chimney thimble. Galvanized steel vent connector for Category I, draft-hood equipped gas appliances. Single-wall connector requires 6" clearance to combustibles — where that cannot be held, Type B double-wall vent is the correct choice.
