Overview
Complete 6" Class A chimney kit for venting a freestanding wood stove out through an exterior wall and up the outside of the house. Every AllFuel HST part you need at the wall in one order: stove pipe adapter, wall thimble, a short section of chimney pipe to pass through the wall, tee with clean-out cap, base wall support kit, wall bracket and spark screen chimney cap. No Sales Tax.
Who it's for: a wood stove with a 6" flue collar where going up through the ceiling isn't practical, so the chimney exits the wall and runs up the exterior.
Choosing options: pick the through-wall pipe length that spans your wall thickness, and the wall bracket. The standard bracket holds 2" clearance to the wall; the adjustable bracket ranges from 2" to 7".

Vertical chimney pipe is not included. Like AllFuel's own through-the-wall kit, this kit includes only the short pipe that passes through the wall. Add AllFuel HST 6" Class A chimney pipe in lengths that add up to the run from the tee up to the cap.
Single wall stove pipe sold separately. Connect the stove to the stove pipe adapter with AllFuel HST 6" black single wall stove pipe.
Good to know
- The wall thimble needs an 8" hole in the wall.
- Add a wall bracket at least every 8 ft of vertical run above the base support. One bracket is included.
- Sold separately if your install needs them: roof flashing, storm collar, 15 degree elbow kit and additional wall brackets.
- 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.
