AllFuel HST 6″ X 48″ Insulated Chimney Pipe
The AllFuel HST 6″ x 48″ insulated chimney pipe uses 304 stainless steel both inside and out, with laser-welded seams for corrosion resistance. Its ceramic fiber blanket provides a 2″ clearance to combustibles while maintaining high internal flue temperatures for a proper draft. This pipe is compatible with AllFuel HST Class-A double wall systems and is designed for long, straight-through runs. Best for straight, through-wall or through-ceiling installations when using AllFuel HST components. Limitation this piece is not compatible with non-AllFuel Class-A brands, so ensure you match parts in the system.
AllFuel HST Through The Wall Kit With Flat Top Chimney Cap
This kit is designed for through-wall installations with a 6″ diameter AllFuel HST Class-A double-wall insulated chimney pipe. It includes a flat-top cap and the necessary components to pass through a wall thimble. Best for exterior wall passes and exterior clearance considerations. Limitation you must measure wall thickness and add extra length if the pipe is exposed outside the house or enclosed in a chase.
AllFuel HST 30 Degree Elbow Kit (6″ Diameter)
The 30 Degree Elbow Kit is compatible with AllFuel HST Class-A double-wall insulated chimney pipe. It features 304 stainless steel inner and outer walls with laser-welded seams and a ceramic fiber blanket for a 2″ clearance to combustibles, aiding draft. Best for navigating corners in tight spaces. Limitation elbows add resistance; plan the layout to minimize the number of turns.
AllFuel HST Through The Attic Kit With Spark Guard Chimney Cap
This attic installation kit is built for single-story flat ceilings or vaulted ceilings with attic space. It includes a square ceiling support box, attic insulation shield, roof flashing, a spark-guard chimney cap, and a black stove pipe adapter. Best for attic-through installations where you need a complete package. Limitation pipe lengths must be purchased separately to reach the final appliance.
AllFuel HST Through The Wall Kit With Adjustable Wall Bracket (9″ Length)
This through-the-wall kit offers a 9″ adjustable wall bracket, allowing up to 7″ extension to clear gutters or overhangs. It includes guidance for wall thickness and vertical rise. Best for passes through exterior walls with variable thickness. Limitation ensure you have the correct pipe lengths sold separately to complete the installation.
DuraVent DVL 6×6 Inch Ceiling Chimney Connector Kit
The DuraVent DVL kit is a stainless steel double-wall ceiling connector designed for durable, local manufacturing in the United States. It provides straightforward installation with easy-to-use components and a reliable ceiling transition. Best for builders seeking a robust ceiling connection. Limitation verify compatibility with the stove and ceiling height, as some systems have specific clearance requirements.
Buying Guide
What type of chimney pipe material matters?
Stainless steel (304) walls resist corrosion better than galvanized steel or 430 stainless. For insulated, double-wall Class-A systems, stainless construction offers the longest life in venting through combustible spaces.
What should I consider for through-wall vs through-ceiling installations?
Through-wall kits focus on exterior exposure and thimble clearance. Through-ceiling or attic kits emphasize ceiling support boxes, roof flashing, and attic shields. Choose a kit that includes or accommodates the necessary components for your house type.
How do elbows and turns affect performance?
Every added elbow increases backpressure and reduces draft efficiency. Use as few turns as possible and plan long, straight runs when feasible. If turns are necessary, opt for high-quality elbows with proper welds and seal integrity.
What clearance and safety considerations apply?
Insulation and ceramic fiber blankets are designed to keep combustibles at a safe distance (typically around 2″). Verify that your installation maintains required clearances and that brackets or passing through walls provide the needed stability and airflow.
How do I choose between through-wall and attic kits?
Through-wall kits are ideal when the exhaust must pass directly through an exterior wall. Attic kits suit spaces with an upper ceiling and attic access, enabling a clean indoor path from stove to vent exit with protection against attic heat and weather.
What should I check before purchase?
Confirm compatibility with your stove or appliance model, confirm that lengths of pipe are available to reach the final vent outlet, and ensure you have all required brackets, caps, and supports listed in the kit or compatible accessories.
How can I ensure a clear, compliant install?
Follow the manufacturer’s installation instructions, maintain recommended clearances, and ensure all joints are properly sealed and supported. If in doubt, consult a professional installer familiar with AllFuel HST or DuraVent Class-A systems.
FAQ
- What is the advantage of a double-wall insulated chimney pipe? It reduces heat loss, improves draft, and minimizes clearance requirements to combustibles.
- Can I mix brands within a single chimney system? Most kits are designed to be brand-specific to ensure compatibility, so avoid mixing brands unless explicitly stated as compatible.
- Do these kits include all necessary components? Some kits are comprehensive (for attic or wall installs) while others require purchasing extra pipe lengths separately.
- Is 304 stainless steel necessary for residential venting? 304 stainless steel provides superior corrosion resistance and is common in higher-quality insulated systems.
- How do I determine the correct wall thickness for a through-wall kit? Measure the wall thickness where the thimble will pass and add extra length if the pipe will be exposed outside the house or placed in a chase.
- What is UL 103HT, and why does it matter? UL 103HT indicates testing for hearth-type applications; select components listed to meet applicable safety standards for your installation.
