For a wall-supported chimney system with a horizontal length passing through an exterior wall, connecting to a Tee and running vertically up the exterior wall to termination above the roof line. The Thru-The-Wall-Support Kit provides all necessary parts for a complete installation with the exception of required Insulated Pipe Lengths to reach your desired chimney height. This superior insulation maintains higher internal flue temperatures, enhancing draft and efficiency. Low temperatures are maintained on the outer casing, allowing installation as close as 2" from combustible materials. Assembled with the Positive Joint Coupler, the safest and most secure locking system in the industry, Ultra-Temp and Galva-Temp chimney sections twist together with a 1/8 turn. A locking band ensures system integrity and strength for the life of the chimney. Selkirk again sets the industry standard.
