Ask & Answer
When your chimney needs an extension, this chimney pipe length will just fit the bill. The pipe length can adjust to any length between 3 and 8 inches. Its stated purposes include, as well, venting category 1 appliances and connecting 3" Metal-Fab pipes of a certain type to male ends of specified other brands of pipes. It includes a 1/4 inch insulating air space as well as a double-wall design to keep space between the chimney and any surrounding combustibles. The flue and casing are hemmed in order to prevent injuries from sharp edges. A limited one year warranty is included.
* Please Note: Pipe overlaps 1.5" when joined together. Therefore, the assembled length is 1.5" less than listed.
