The best wood stove wall kit depends on your stove-pipe diameter and the chimney system you plan to use. For a 6-inch DuraPlus installation, consider the DuraVent kit; for AllFuel HST Class-A pipe, choose the matching 6-inch or 8-inch kit. The Selkirk kit is another 6-inch option, while the DuraVent PelletVent kit is for pellet-stove exhaust, not a standard wood-stove chimney. Check system compatibility and installation clearances before buying.

DuraVent DuraPlus 6-Inch Through-Wall Kit
This kit is best for buyers planning a through-wall vertical chimney installation using 6-inch DuraPlus chimney pipe. Its secure twist-lock design connects compatible chimney components, and the kit is described as supporting up to 40 feet of chimney pipe.
Choose this option if your project already uses, or is designed around, DuraPlus components. It was selected for its direct fit with a named chimney system and stated support for a substantial chimney height. The chimney pipe itself is not included, so plan to source the required lengths separately.
Limitation: The listed compatibility is specific to 6-inch DuraPlus pipe. Do not assume it connects to a different brand or pipe system.
AllFuel HST 6-Inch Kit With Flat Top Cap
This kit is best for a 6-inch AllFuel HST Class-A double-wall insulated chimney installation. The supplied information describes a flat top chimney cap and a 24-inch length, while chimney-pipe lengths are sold separately. Buyers can choose a standard wall bracket with 2 inches of clearance or an adjustable bracket that extends up to 7 inches to pass a gutter or small overhang.
It is a useful choice when the project needs the adjustable bracket option or when the route through the wall requires careful pipe-length planning. The listed instructions say to measure wall thickness and add at least 5 inches for exposed exterior pipe, or 8 inches if the pipe is enclosed in a chase.
Limitation: This kit is compatible with AllFuel HST Class-A pipe and cannot connect to other brands’ Class-A chimney pipe. Additional support brackets may be needed for long vertical runs.
Selkirk 6-Inch Stove Wall Kit
This Selkirk kit is best for buyers looking for a 6-inch through-wall stove-pipe option. Its listed features include double-wall construction and a design intended to simplify venting through an exterior wall. The product description says it is designed to work with most 6-inch stove-pipe systems.
Choose it if a 6-inch setup and a double-wall design match your project requirements. It was selected as a straightforward alternative to the brand-specific AllFuel and DuraVent kits. However, “most” does not mean every system: verify the exact pipe type and installation requirements before purchase.
Limitation: The available product details do not specify included pipe lengths or list all compatible systems. Confirm what is included and whether additional chimney components are required.
AllFuel HST 8-Inch Kit With Spark Guard Cap
This kit is best for projects that require an 8-inch AllFuel HST Class-A double-wall insulated chimney system. It includes an 18-inch length and a spark guard chimney cap, according to the product name. Buyers can select a standard wall bracket providing 2 inches of clearance or an adjustable bracket extending up to 7 inches.
Choose this model over the 6-inch AllFuel kit only when the stove and chimney plan call for an 8-inch diameter. Its adjustable bracket can help route pipe past a gutter or small overhang. As with the 6-inch version, the listed guidance calls for measuring the wall and adding the appropriate length for exposed pipe or a chase.
Limitation: It is designed for AllFuel HST pipe and cannot be connected to other brands’ Class-A chimney pipe. Pipe lengths are sold separately, and extra wall brackets may be needed for extended vertical runs.
DuraVent PelletVent 3-Inch Horizontal Kit
This kit is best for pellet and multi-fuel stove exhaust applications that require 3-inch double-wall vent pipe. It is not the same type of chimney kit as the 6-inch wood-stove options above. The listed package includes five 12-inch pipes, a 90-degree elbow tee, cleanout tee and cap, appliance adapter, wall thimble, horizontal termination cap, and instructions.
Choose this kit when the appliance is a compatible pellet or multi-fuel heater and the installation calls for horizontal through-the-wall venting. Its stainless-steel inner wall and galvalume outer wall are specified for indoor pellet-stove venting.
Limitation: Its 3-inch size and stated pellet/multi-fuel application make it unsuitable as a substitute for a standard wood-stove chimney system. Confirm the appliance’s venting requirements.
Buying Guide
Which diameter and chimney brand do you need?
Start with the stove or appliance manual and the chimney plan. A 6-inch kit is not interchangeable with an 8-inch kit, and a Class-A chimney component may be brand-specific. The AllFuel HST kits explicitly require matching AllFuel HST pipe. The DuraVent DuraPlus kit is specified for DuraPlus pipe, while the Selkirk listing describes compatibility with most 6-inch stove-pipe systems. Confirm the complete system before ordering.
What should you measure before buying?
Measure the wall thickness and consider whether exterior pipe will remain exposed or sit inside a chase. The AllFuel instructions call for adding at least 5 inches for exposed pipe or 8 inches for pipe enclosed in a chase when determining the length passing through the wall thimble. Also check for nearby gutters and overhangs to decide whether an adjustable bracket is useful.
Is the kit complete?
Compare the included parts with the installation plan. The PelletVent listing gives a detailed component list, but the wood-stove kit descriptions note that chimney lengths may be sold separately. A wall kit may be only one part of the venting system. Check whether the required pipe, brackets, supports, and termination components are included or need separate purchase.
What about clearances and installation?
Follow the appliance and chimney manufacturers’ installation instructions, including stated clearances and support requirements. The AllFuel listing says a wall bracket is required for every 8 feet of vertical rise above the base wall support. Do not use a general description such as “double wall” as a substitute for checking the required system specifications. Consult a qualified installer if the route or clearances are uncertain.
Frequently Asked Questions
Can a pellet-stove vent kit be used for a wood stove?
Not based on the supplied product details. The DuraVent PelletVent kit is described for pellet and multi-fuel stove exhaust, while a wood stove requires a chimney system specified for that appliance.
Does a through-wall kit include all chimney pipe?
Not necessarily. The DuraVent DuraPlus kit supports chimney pipe that is not included, and AllFuel HST pipe lengths are sold separately. Check each kit’s included-parts list.
Can I mix chimney brands?
Do not assume components from different brands connect. The AllFuel HST product details specifically state that its Class-A pipe cannot connect to other brands’ Class-A chimney pipe.
How do I choose between 6-inch and 8-inch kits?
Use the diameter required by the appliance and the planned chimney system. Do not choose a size based only on convenience or appearance.
When is an adjustable wall bracket useful?
An adjustable bracket can extend up to 7 inches on the listed AllFuel HST kits, which may help pass a gutter or small overhang. Confirm the required clearance for the specific installation.
