AllFuel HST Cathedral Ceiling Kit With Spark Guard Cap (11″ Ceiling Box)
This kit is designed for AllFuel HST Class-A double-wall chimney pipe. It utilizes an 11″ square ceiling support box and a 1/12-6/12 pitch roof flashing. The system is best for single-story homes with a cathedral ceiling (no attic space) or vaulted ceilings with attic space. The ceiling box supports up to 45 feet of chimney pipe, which makes it suitable for mid-range vertical runs. It includes a black stove pipe adapter, a ceiling support box with trim kit, a roof flashing with storm collar, and a spark-guard chimney cap.
Who it’s best for: buyers with AllFuel HST pipes looking for a complete, plug-and-play ceiling kit for straightforward cathedral ceilings. Why selected: strong compatibility within the AllFuel HST ecosystem and balanced kit contents for a standard install.
Caution: pipe lengths are sold separately, so total cost depends on run length. Consider whether your ceiling height and stove placement require longer sections.

This pitched ceiling kit from Selkirk Sport is designed for cathedral or pitched ceilings, including standard A-frame configurations. It provides all necessary parts for a complete installation and is tailored to support a clean, code-compliant venting path from stove or fireplace to the roof.

Who it’s best for: homeowners with a cathedral or pitched ceiling seeking a full, ready-to-install package. Why selected: comprehensive components included to simplify the project.

It remains compatible with AllFuel HST Class-A double-wall chimney pipe, with pipe lengths sold separately. It’s a strong option for single-story or vaulted ceilings where more space around the ceiling box is beneficial.
Who it’s best for: installers needing a bigger ceiling support box for complex cathedral layouts. Why selected: versatility in ceiling box size enables different room geometries while maintaining kit completeness.
Caution: larger box adds some overhead in ceiling cavity space; confirm attic access and structural clearances before purchase.

This kit is well-suited for homes where a straightforward through-the-ceiling install is preferred and the pipe length can be bought separately to fit the run.
Who it’s best for: buyers prioritizing durability and a through-the-ceiling approach for longer vertical runs. Why selected: reliable build quality with a clear pipe-length planning path.
Caution: not a complete package—requires purchasing the appropriate pipe lengths separately to complete the installation.

Buying Guide: Cathedral Ceiling Chimney Kit Essentials
What to consider when choosing a cathedral ceiling chimney kit:
- Ceiling type: cathedral vs vaulted ceilings; attic access plays a key role in determining if a larger box is needed.
- Diameter and compatibility: confirm pipe diameter (commonly 6″) and brand compatibility with Class-A double-wall pipes.
- Box size vs attic space: larger ceiling boxes offer more routing flexibility but require more cavity space.
- All-in-one vs modular: some kits include every part, while others require separate purchase of pipe lengths.
- Through-ceiling vs pitched: select based on roof geometry and interior/exterior routing.
- Ice and weather considerations: roof flashing and storm collars help prevent leaks in snowy climates.
