Every AllFuel HST part you need at the ceiling, attic and roof in one order: stove pipe adapter, ceiling support box, attic insulation shield, roof flashing, storm collar and spark screen chimney cap. Pick your ceiling support box size, roof pitch and how much chimney pipe to include above. No Sales Tax.
Who it's for: a single-storey, through-the-ceiling install of a wood stove with a 6" flue collar, where the chimney rises straight from the ceiling through the attic and out the roof.

How much pipe do you need? Measure from the bottom of the ceiling support box, up through the attic, to at least 3 ft above the roof where it exits and 2 ft higher than anything within 10 ft. Pick the option that covers that run. If you need a different length, choose "No chimney pipe" and add AllFuel HST 6" Class A chimney pipe in lengths from 6" to 48".

Good to know
- The ceiling support box can support a maximum of 50 ft of chimney and includes a black trim collar.
- If the chimney passes through a second floor, add a firestop radiation shield at each floor.
- If an attic obstruction is in the way, add the 15 degree elbow kit.
- If the chimney extends more than 5 ft above the roof, an extended roof brace must be installed.
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. Inner and outer walls are 0.019" 304 stainless steel with 1.18" ceramic fiber insulation between them. Keep at least 2" clearance between the chimney pipe and any combustible materials. Not for forced draft or positive-pressure appliances.
AllFuel HST parts connect only to 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.
