AllFuel HST Cathedral Ceiling Kit With Flat Top Cap
This kit provides a 24″ square ceiling box and a flat-top chimney cap option, compatible with AllFuel HST Class-A double-wall pipe. It is suited for single-story cathedral or vaulted ceiling homes. Like other AllFuel options, pipe lengths are sold separately, and the kit includes the essential components: a black stove pipe adapter, a trim-ready ceiling box, roof flashing, and a spark arrestor cap.

AllFuel HST 24″ Tall Square Ceiling Box
This product is a 24″ tall square ceiling support box and is intended for cathedral or vaulted ceilings up to an 8/12 pitch. It works with AllFuel HST Class-A double-wall chimney pipes but cannot be connected to other brands. It provides sturdy support and a robust finish for installations that require a taller ceiling box. It’s best for builders who need a dedicated support solution separate from a complete kit.
Best for: installations needing a tall support box or upgrading an existing run. Caution: Pair with AllFuel HST pipe lengths and confirm roof pitch compatibility.
Buying Guide
Which cathedral ceiling venting option is right for you depends on ceiling height, roof pitch, and the type of cap you prefer. A complete kit with a ceiling box, roof flashing, and cap simplifies ordering and installation, while a separate ceiling box can be paired with existing pipes.
- Only use AllFuel HST Class-A double-wall pipes with these kits unless stated otherwise.
- For ceilings with little attic space, a 24″ square box generally provides more room for pipe routing and clearance.
- Spark arrestor caps reduce ember risk; flat-top versus standard domed caps affect appearance and airflow.
- Confirm your ceiling pitch (1/12, 7/12, 8/12, etc.) to ensure the roof flashing and support box align correctly.
- If UL103HT certification matters for your installation, choose the kit noted as certified for wood stoves and similar appliances.
- A smaller 11″ box saves ceiling space but may limit pipe length; plan pipe runs accordingly.
