Overview
6" double wall insulated Class A chimney pipe. This is the pipe that runs from the ceiling support box up through the attic and roof. Choose lengths that add up to your total chimney height.
AllFuel HST Class A chimney is certified and listed to UL 103HT, rated for continuous use at 1000°F, and designed for appliances listed for use with a 2100°F high-temperature chimney. Keep at least 2" clearance between the chimney pipe and any combustible materials. Not for forced draft or positive-pressure appliances.
Build the whole chimney from AllFuel HST parts. Factory-built chimneys are tested as a system, so never mix in parts from another chimney brand, and install exactly per the manufacturer's instructions and local code.
