Customer Reviews
Ask & Answer
This chimney pipe length is 3" (inner diam.) x 36" and is designed for venting Category I appliances like gas-fired fireplaces, furnaces, boilers, and water heaters. The Metal-Fab Type B piping system is made with a dual wall design. The outer wall is 0.018" galvanized steel and an 0.012" aluminum alloy is used for the wall with a 1/4" insulating air space between. This design permits a clearance to combustible materials of 1". The casing has no dangerous sharp edges, and the SureLock connection makes it easy to join lengths of pipe without tools. This item is compatible with other brands of Type B gas vent pipe. Listed to UL 441, this pipe carries a one-yar limited warranty.
* Please Note: Pipe overlaps 1.5" when joined together. Therefore, the assembled length is 1.5" less than listed.
