Selkirk 6 in. D X 18 in. L Stainless Steel Chimney Pipe

Designed for appliances tested and listed for use with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters or other appliances fueled by wood, oil, coal, or gas. To calculate the installed length of Ultra-Temp chimney pipe, subtract 1 1/4" from each length of chimney pipe.Engineered for safety, Selkirk, also known as MetalBest or MetalBestos, chimneys are packed with one inch of premium fiber insulation, ensuring a 100% fill. 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.
