DuraVent DuraPlus 6-Inch Through-Wall Kit

This kit is best for a buyer planning a through-wall vertical chimney installation with 6-inch DuraPlus chimney pipe. Its stated features include a secure twist-lock design and support for up to 40 feet of chimney pipe. The chimney pipe itself is not included, so the buyer must plan and source compatible pipe separately.
Choose this option when the existing or planned chimney system is DuraPlus and the pipe diameter is 6 inches. The stated 40-foot support capacity may help with planning a taller chimney run, but it does not replace checking the appliance instructions, chimney instructions, and local requirements for the specific installation.
- Best for: A 6-inch DuraPlus through-wall installation.
- Selected because: The product description identifies its intended pipe system and mentions a twist-lock connection.
- Limitation: Chimney pipe is sold separately, and the provided details do not list every included component.
AllFuel HST 6-Inch Kit With Standard Bracket

This AllFuel HST kit is best for a 6-inch installation using AllFuel HST Class-A double-wall chimney pipe. The product description specifies a 24-inch length, a standard wall bracket, and a spark guard chimney cap. It also says that chimney lengths are sold separately and that the kit cannot connect to other brands of Class-A chimney.
The standard bracket provides 2 inches of clearance, according to the listing. The instructions also state that a bracket is required for every 8 feet of vertical rise above the base wall support. If the outside wall has a gutter or small overhang, compare the standard bracket’s reach with the obstruction before choosing this version.
- Best for: Buyers using a matching 6-inch AllFuel HST chimney system.
- Selected because: The listed contents include a spark guard cap and standard wall bracket.
- Limitation: It is not compatible with other brands of Class-A chimney, and additional pipe lengths are separate.
Selkirk Metalbestos 8-Inch Complete Kit

This Selkirk Metalbestos option is best for buyers who specifically need an 8-inch complete stove through-wall kit. The provided product information describes it as easy to use and durable, but does not detail the included parts, pipe length, wall clearance, or connection system. Confirm those particulars with the product documentation before ordering.
Choose this kit only after confirming that the stove outlet and chimney plan call for an 8-inch system and that this kit matches the intended chimney components. A larger diameter should not be selected simply because it seems more robust; follow the stove manufacturer’s venting requirements and applicable codes.
- Best for: A buyer seeking an 8-inch Selkirk through-wall kit.
- Selected because: It is explicitly identified as a complete 8-inch stove through-wall kit.
- Limitation: The available product details are sparse, so included components and installation clearances need verification.
AllFuel HST 8-Inch Kit With Adjustable Bracket

This kit is best for an 8-inch AllFuel HST Class-A double-wall chimney installation where the wall support needs additional projection. The listing specifies an 18-inch length, an adjustable wall bracket, and a spark guard chimney cap. It is designed for AllFuel HST pipe only; the product description says it cannot connect to other brands of Class-A chimney.
The adjustable bracket extends up to 7 inches, which can help the support pass a gutter or small overhang. The listing says a wall bracket is required for every 8 feet of vertical rise above the base wall support. Measure the wall and planned exterior route, and confirm the required pipe length for the thimble before purchase.
- Best for: Matching 8-inch AllFuel HST systems with an obstruction near the wall support.

This Selkirk option is best for a buyer whose installation calls for a 6-inch Selkirk through-wall kit. The product details identify it as a 6-inch complete stove through-wall kit made of stainless steel. They do not specify the package contents, wall clearance, pipe length, or installation method, so check the manufacturer’s instructions and product documentation to confirm the fit.
It is a reasonable product to compare with the other 6-inch choices when a Selkirk system is planned. Do not assume that a kit from one brand will connect to another brand’s chimney components; confirm system compatibility before buying.
- Best for: Buyers seeking a 6-inch stainless-steel Selkirk through-wall kit.
- Selected because: Its description directly identifies the diameter and complete-kit purpose.
- Limitation: The supplied details do not explain included parts or compatibility with other systems.
Buying Guide: How To Choose A Through-Wall Chimney Kit
Which diameter should you buy?
Start with the stove manufacturer’s venting instructions and the appliance outlet size. The product options here include 6-inch and 8-inch kits, but those sizes are not interchangeable by preference alone. Follow the stove’s specified vent diameter and any approved configuration. If the appliance instructions are unclear, ask a qualified chimney professional before selecting parts.
Does the kit have to match the chimney brand?
Check the exact chimney system named by the kit manufacturer. The AllFuel HST listings specifically state that their kits work with AllFuel HST Class-A double-wall pipe and cannot connect to other brands of Class-A chimney. For the other kits, the supplied descriptions do not provide enough information to establish cross-brand compatibility. Do not mix components unless the manufacturer confirms that combination is permitted.
What is the difference between connector pipe and chimney pipe?
A typical through-wall wood-stove route uses stovepipe inside the room to reach a wall pass-through, then insulated chimney components to continue through the wall and upward outdoors. These are different parts of the venting system and may have different clearances and connection requirements. Follow the stove and chimney manufacturers’ instructions for each section. Do not treat ordinary indoor connector pipe as a substitute for insulated chimney pipe through a wall.
How do you choose the wall bracket?
Consider the exterior wall layout, the planned chimney position, and nearby features such as gutters or small overhangs. The 6-inch AllFuel HST option has a standard bracket that provides 2 inches of clearance. The 8-inch AllFuel HST option has an adjustable bracket that extends up to 7 inches. The AllFuel HST listing also calls for a bracket every 8 feet of vertical rise above the base wall support. Verify support spacing in the full installation instructions.
How should the wall opening and pipe length be planned?
Measure the full wall assembly that the chimney passes through, including interior and exterior finishes. The AllFuel HST directions say to measure wall thickness and add at least 5 inches if pipe is exposed outside, or 8 inches if it is enclosed in a chase, when choosing the pipe length through the wall thimble. These are product-specific directions; consult the instructions for the exact system being installed. Do not cut or alter components unless the manufacturer allows it.
What safety and code checks matter?
Wood-stove venting involves fire and carbon-monoxide risks. The wall pass-through, clearances to combustible materials, support locations, chimney height, termination, and required components must follow the stove and chimney instructions and local building and fire codes. Requirements can differ by location and installation. Have the plan reviewed by the local authority or a qualified chimney professional, especially before cutting an exterior wall or enclosing a chimney in a chase.
What should you confirm before ordering?
- Confirm the required chimney diameter and system name from the stove and chimney instructions.
- Check whether chimney lengths and other components are included or sold separately.
- Measure the wall thickness and identify exterior obstructions before selecting a bracket or pipe length.
- Verify the exact package contents, clearances, support requirements, and installation steps in the manufacturer’s documentation.
- Check local code requirements and obtain any required approvals before installation.
Frequently Asked Questions
Can a wood stove pipe go directly through an exterior wall?
The complete venting system must use components intended for the specific wall pass-through and chimney route. A typical installation uses a suitable wall pass-through and insulated chimney pipe after the interior connector pipe. Follow the appliance and chimney instructions rather than routing ordinary stovepipe through a combustible wall.
Can I connect AllFuel HST components to another chimney brand?
The AllFuel HST product descriptions say these kits cannot connect to other brands of Class-A chimney. Use the matching AllFuel HST system unless the manufacturer confirms a different combination is compatible.
Does the DuraVent kit include chimney pipe?
No. The listed DuraVent kit supports up to 40 feet of DuraPlus chimney pipe, but the pipe is not included.
How often does the AllFuel HST chimney need a wall bracket?
The supplied AllFuel HST details say a wall bracket is required for every 8 feet of vertical rise above the base wall support. Confirm the spacing and placement in the full instructions for the chosen kit.
Should I choose the standard or adjustable AllFuel HST bracket?
The standard bracket provides 2 inches of clearance. The adjustable version extends up to 7 inches and may suit a route that must pass a gutter or small overhang. Measure the installation area and verify clearance requirements before choosing.
