Best Through-the-Ceiling Chimney Kits for Wood Stoves
The best through-the-ceiling chimney kit depends on your chimney brand, ceiling style, and roof pitch. The DuraVent DuraPlus kit suits a straightforward 6-inch DuraPlus installation; AllFuel HST kits offer options for attic layouts and different roof pitches; and the AllFuel cathedral kit is designed for sloped ceilings. Selkirk’s ceiling support kit is another option, but confirm that its components match your chimney system before buying. Pipe lengths are sold separately for several kits, so check what is included.
| Kit | Best suited for | Key distinction |
|---|---|---|
| DuraVent DuraPlus Basic | 6-inch DuraPlus installations | Supports up to 35 feet of pipe |
| AllFuel HST Flat Top | Attic routes with steep roof pitches | 7/12–12/12 flashing and flat-top cap |
| AllFuel HST Spark Guard | Attic routes with lower roof pitches | 1/12–6/12 flashing and spark-arrestor cap |
| Selkirk Ceiling Support | Buyers seeking an included support package | Includes support and venting components |
| AllFuel HST Cathedral | Vaulted or cathedral ceiling layouts | Designed for ceiling installations without a standard flat ceiling |
DuraVent DuraPlus Basic Through-The-Ceiling Kit
Best for: Homeowners installing a 6-inch DuraPlus chimney through a ceiling who want a basic kit from the same system brand. Its listed features include a through-the-ceiling installation design and durable 24-gauge construction.
The kit supports up to 35 feet of chimney pipe, which is sold separately. Choose this option when your planned setup uses DuraPlus components and fits within that supported pipe length. The product information identifies it specifically for 6-inch DuraPlus pipe, so it is not a universal kit.
Limitation: Chimney pipe is not included, and the stated support limit is lower than the 45-foot limits listed for some AllFuel HST kits.
AllFuel HST Attic Kit With Flat-Top Cap
Best for: A single-story home with a flat ceiling and attic route, paired with AllFuel HST 6-inch Class-A double-wall chimney pipe. This kit includes a black stove-pipe adapter, an 11-inch square ceiling support box with trim, an attic insulation shield with storm collar, adjustable roof flashing for a 7/12–12/12 pitch, and a flat-top chimney cap.
The ceiling support box can support up to 45 feet of chimney pipe. This gives buyers a clearly stated maximum when planning the chimney run. It is a better fit for a steeper roof than the companion AllFuel option with 1/12–6/12 flashing.
Limitation: Pipe lengths are sold separately, and the kit cannot be connected to other brands of Class-A chimney.
AllFuel HST Attic Kit With Spark Guard
Best for: AllFuel HST installations passing through a flat or vaulted ceiling and an attic, especially where the roof pitch falls between 1/12 and 6/12. The package includes a stove-pipe adapter, ceiling support box with trim, attic insulation shield, roof flashing with storm collar, and a chimney cap with spark arrestor.
Its support box is rated to support up to 45 feet of chimney pipe. The spark-arrestor cap and lower-pitch flashing distinguish it from the flat-top-cap kit. Select the support-box length and roof pitch that match the installation details.
Limitation: The chimney pipe is not included, and the kit is not compatible with other brands of Class-A chimney.
Selkirk Stainless Steel Ceiling Support Kit
Best for: Buyers looking for a ceiling support package with multiple installation components. Listed contents include a round top, storm collar, flashing, attic insulation shield, finish support, and smoke-pipe adapter. The product description identifies it for residential stove, fireplace, and furnace venting.
Stainless steel construction and reinforced parts are also listed features. Compared with the basic DuraVent kit, this option calls out a broader set of included components, which may help buyers who want support and roof-penetration parts in one package.
Limitation: The supplied details do not specify a pipe-length support limit or brand compatibility. Confirm that the kit matches the selected chimney system and installation plan.
AllFuel HST Cathedral Ceiling Kit
Best for: A single-story home with a cathedral or vaulted ceiling, including layouts with no attic space. The kit includes a black stove-pipe adapter, ceiling support box with trim, roof flashing with storm collar, and a chimney cap with spark arrestor. It is specified for AllFuel HST Class-A double-wall chimney pipe.
The support box can support up to 45 feet of pipe. The product listing also describes UL103HT certification and use with residential appliances fueled by wood, gas, coal, or oil. Check the complete installation requirements for the specific appliance and venting layout.
Limitation: Pipe lengths are sold separately, and the kit cannot connect to other brands of Class-A chimney. An extended roof support is also listed as necessary if the chimney extends more than 5 feet above the roof.
Buying Guide: How To Choose A Through-The-Ceiling Chimney Kit
Does the kit match your chimney pipe brand and diameter?
Start with the pipe system, not the kit appearance. The DuraVent option is listed for 6-inch DuraPlus pipe, while the AllFuel kits specify AllFuel HST 6-inch Class-A double-wall pipe and warn against connecting other brands. For the Selkirk kit, confirm compatibility with the manufacturer or product documentation because the supplied details do not name compatible pipe systems.
Is your ceiling flat, vaulted, or cathedral?
Attic kits are intended for routes that pass through a ceiling and attic space. The AllFuel spark-guard attic kit specifically covers flat or vaulted ceilings with an attic. The cathedral kit is intended for cathedral or vaulted layouts, including homes without attic space. Match the support-box design to the actual ceiling structure.
Will the roof flashing fit your roof pitch?
Check the pitch range before ordering. The AllFuel flat-top kit lists flashing for 7/12–12/12 roofs, while the spark-guard attic kit lists 1/12–6/12 flashing. A mismatch can make the kit unsuitable for the roof penetration.
What parts and pipe lengths are included?
Read the package contents carefully. Some kits include support boxes, insulation shields, flashing, storm collars, adapters, and caps, but the AllFuel listings state that chimney pipe lengths are sold separately. Also check stated support limits: the listed DuraVent kit supports up to 35 feet, while the featured AllFuel support boxes are listed for up to 45 feet.
