Specifics
This pipe is designed to cover the distance from 2" ( 5.08 cm ) below the ceiling to the 1 foot ( 30.48 cm ) mark past the roof's highest point. It is insulated and made of stainless steel, and does not carry any flue gases. The 3" flue pipe carries the gases and runs through the 5" pipe.
A 1" air space between the pipe, ceiling and roof is necessary. When in a flat position, a 7" circular hole must be made. If angled, the hole must be an oval shape to ensure an even 1" air space around the pipe.
To properly cut the pipe to the desired length, it is recommended to use an angle grinder with a cutting disc.
A flue pipe brace is necessary when the exterior length exceeds 2 feet.
