It supports wall-through lengths of pipe chosen by your wall thickness and offers two bracket options—standard or adjustable—allowing up to 7″ clearance to accommodate gutters or small roof features. A wall bracket is recommended for every 8 feet of vertical rise above the base wall support.

Buying Guide
Key purchase considerations
- Chimney system compatibility: Choose a kit that clearly matches your 6″ Class-A or double-wall chimney pipe brand and diameter to avoid mismatches and leaks.
- Wall thickness and exposure: Measure wall thickness accurately and decide if you need a longer through-the-wall length or an exterior chase. Plan for extra length if the pipe will be exposed outside.
- Bracket type and clearance: Standard brackets offer fixed clearances, while adjustable brackets provide flexibility for rooftops, gutters, or overhangs. Ensure they support your vertical rise safely.
- Weatherproofing and caps: A rain cap or spark guard helps prevent debris or embers from entering the system. Select components with durable caps and proper flashing for roof pitches.
- Durability and material: Stainless steel (SUS304) offers corrosion resistance in outdoor installations, contributing to longer life and reduced maintenance.
- Installation complexity: Some kits include all components for a complete install; others require purchasing additional straight pipe lengths separately. Consider your DIY comfort level.
- Safety standards: Look for UL/ULC listed components and assemblies to ensure compliance with household safety regulations.
To ensure a balanced comparison, assess total installed height, required brackets, and whether the kit supports extensions for higher risers. If you plan future upgrades or height increases, factor in additional components like extra brackets and straight pipes. For repairs or replacements, verify that the kit’s components are compatible with the existing chimney system to minimize retrofit work.
