Best Wood Stove Chimney Kits for Different Installation Types
The best wood stove chimney kit depends on whether the chimney passes through a wall, a ceiling, or an existing masonry chimney. The DuraVent DuraPlus kit is suited to a through-the-wall Class A installation, while the Fireside Chimney Supply kits are for lining an existing chimney. AllFuel HST offers through-wall and cathedral-ceiling options for its own chimney system. Check appliance and local code requirements before choosing.
| Kit | Best For | Key Detail |
|---|---|---|
| DuraVent DuraPlus Through the Wall | Through-wall installation | For 6-inch DuraPlus chimney pipe |
| Fireside Basic FireSafe Liner | Vertical liner hookup | 15-foot liner with appliance connector |
| Fireside Liner With Tee | Horizontal appliance hookup | 15-foot liner with tee connector |
| AllFuel HST Through the Wall | AllFuel HST wall exit | Adjustable wall bracket included |
| AllFuel HST Cathedral Ceiling | Vaulted or cathedral ceiling | Support box, flashing, and cap included |
DuraVent DuraPlus Through the Wall Kit
This kit is designed for a 6-inch DuraPlus chimney pipe installation that exits through a wall before rising vertically outdoors. Its twist-lock design secures compatible chimney sections, and the listed system can support up to 40 feet of chimney pipe. The pipe itself is not included.
Best for: Buyers planning a through-the-wall route who are assembling a DuraPlus system. It is selected for its clear installation type and stated pipe-support capacity. Limitation: It is not a complete pipe package, and the listed compatibility is specific to DuraPlus pipe.
Fireside Basic FireSafe Flexible Liner Kit
This 6-inch-by-15-foot kit is intended to line an existing chimney. It includes a flexible stainless steel liner, a 13-by-13-inch top plate with rain cap, and an appliance connector for vertical hookups. The product listing describes 316 stainless steel, 7-ply seams, and 10 corrugations.
Best for: Owners with an existing chimney and a vertical appliance connection who need a liner rather than an exterior Class A chimney system. Limitation: The 15-foot liner length may not suit every chimney; measure the flue and confirm the required configuration before ordering.
Fireside FireSafe Liner Kit With Tee
This kit also uses a 6-inch-by-15-foot flexible liner and includes a top plate with rain cap. Its listed connector is a tee for horizontal hookups, making it distinct from the vertical-connector version. The listing specifies 316L stainless steel, a .006-inch liner, 7-ply seams, and 10 corrugations.
Best for: Buyers relining an existing chimney when the appliance connects horizontally. The tee makes it the more relevant choice than the basic kit for that layout. Limitation: It is a liner kit, not a full exterior chimney system, and its listed liner length is 15 feet.
AllFuel HST Through-the-Wall Kit
This kit is for 6-inch AllFuel HST Class A double-wall chimney pipe. It includes a 24-inch pipe length and a wall bracket, with standard and adjustable bracket configurations described in the product information. The adjustable bracket can extend up to 7 inches to clear a gutter or small overhang. Additional pipe lengths are sold separately.
Best for: Buyers planning a through-wall installation with AllFuel HST pipe, especially where extra bracket clearance may be useful. Limitation: It cannot be connected to other brands of Class A chimney pipe. The correct pipe length through the wall depends on wall thickness and whether the exterior pipe is exposed or enclosed.
AllFuel HST Cathedral Ceiling Kit
Designed for a 6-inch AllFuel HST chimney, this kit is intended for cathedral or vaulted ceiling installations. Included parts are a stove pipe adapter, ceiling support box with trim, roof flashing with storm collar, and chimney cap with spark arrestor. The support box is listed for up to 45 feet of chimney pipe; pipe lengths are sold separately.
Best for: Buyers routing a compatible chimney straight through a cathedral or vaulted ceiling and roof. Limitation: It is limited to AllFuel HST pipe. An extended roof support may be needed if the chimney extends more than 5 feet above the roof, according to the product details.
Buying Guide: How to Choose a Wood Stove Chimney Kit
Will the chimney pass through a wall or the roof?
A through-the-wall kit is for a route that exits a side wall and continues upward outside. A cathedral-ceiling kit supports a route through the ceiling and roof. A liner kit serves a different purpose: it fits inside an existing chimney. Choose based on the actual route and the structure, not simply on the word “kit.”
Does the kit match your pipe system?
Chimney components are not automatically interchangeable across brands. The AllFuel HST listing specifically says it cannot connect to other brands of Class A chimney. Confirm the pipe diameter, system brand, appliance requirements, and component connections before purchasing.
Which connector does your layout require?
For an existing chimney liner, compare the appliance connection direction. The Fireside basic kit lists a connector for vertical hookups; the other Fireside option includes a tee for horizontal hookups. Confirm that the connector type fits the planned installation.
What else may need to be purchased?
Some kits include support, flashing, or a cap but exclude the chimney pipe needed to complete the run. Others include a limited pipe length. Measure the route, wall thickness, ceiling height, and roof projection, then check the kit contents and installation instructions. Have the planned installation reviewed against applicable local codes and appliance instructions.
Frequently Asked Questions
Can a chimney liner kit replace a through-the-wall chimney kit?
No. A liner kit is designed to line an existing chimney. A through-the-wall kit is intended for a chimney route that passes through a wall and rises outside.
Are all 6-inch chimney kits interchangeable?
No. A matching diameter alone does not establish compatibility. Check the brand, chimney system, appliance specifications, and installation instructions.
Does a chimney kit include all the pipe needed?
Not necessarily. The DuraVent DuraPlus kit listing says chimney pipe is not included, and the AllFuel HST cathedral kit also requires separately purchased pipe lengths.
How do I choose between a tee and a vertical connector?
Choose according to the appliance connection and liner layout. The listed Fireside basic kit has a vertical appliance connector; the other listed kit includes a tee for horizontal hookups.
What should I confirm before buying?
Verify the pipe diameter and system brand, installation route, required length, connector type, included components, appliance instructions, and local code requirements.
