Duravent 6″ DuraPlus Through the Wall Kit
Best for: Through-the-wall installations when a 6″ DuraPlus system is chosen. This kit provides a secure twist-lock connection and is rated to support long vertical runs. It is a solid option for homeowners replacing an exterior chase or adding a new exterior vent. The main caution is that pipe length is not included; you’ll need to purchase piping separately for longer runs.
Fireside Chimney Supply Basic FireSafe Flexible Chimney Liner Insert Kit
Best for: Flexible liner installations when flexibility and high durability matter. This kit uses premium 316 stainless steel with 7-ply seams and 10 corrugations to form a gas- and watertight liner. It includes a top plate with rain cap and an appliance connector for vertical hookups. Caution: Flexible liners can be less rigid than rigid piping in long, straight runs, which may influence draft in certain layouts.
Fireside Chimney Supply Stainless Steel Chimney Liner Kit | FireSafe 6″ x 15′
Best for: Rigid-liner installations with horizontal or vertical sections. This 6″ x 15′ FireSafe liner uses 316L stainless steel for durability and a 7-ply seam design for a robust, moisture-resistant system. It includes a top plate and a tee connector for easier, more secure installations. Caution: As with most rigid systems, precise measurement and cutting are essential to ensure a proper fit through walls or ceilings.
DuraVent DVL 6 x 6 Inch Ceiling Kit
Best for: Ceiling installations in wood-burning setups requiring a robust, double-wall stainless path. The DVL kit is designed for easy use and long-term durability, making it a solid choice for new builds or remodels where the ceiling penetration must handle higher heat loads. Limitation: This kit focuses on the ceiling portion and may need additional through-wall components for a full run.
AllFuel HST Cathedral Ceiling Kit
Best for: Cathedral or vaulted ceilings with limited attic space. This kit includes a ceiling support box, trim kit, roof flashing, and a spark-guard-cap assembly, designed to simplify installation in high ceilings. Caution: Lengths of AllFuel HST pipe are sold separately, so you’ll need to account for additional piping to reach the desired height.
Buying Guide
- Installation type: Choose a kit designed for your space—through-the-wall, ceiling, or cathedral ceiling—to minimize custom cutting and ensure proper clearances.
- Pipe compatibility: Verify that the kit matches your stove and chimney type (rigid vs. flexible, class-A, or double-wall). Mismatches can affect safety and performance.
- Length and routing: Measure wall thickness, ceiling height, and exterior clearances. Some kits include brackets or caps, while others require additional accessories.
- Durability and material: Stainless steel options (316 or 316L) offer better corrosion resistance and longevity in high-heat or damp environments.
- Weather and moisture controls: Top plates, rain caps, and flashing reduce moisture intrusion and creosote-related issues, improving efficiency and reducing maintenance.
- Professional installation: Some configurations (especially class-A and cathedral ceilings) may benefit from professional installation to ensure code compliance and proper venting.
Frequently Asked Questions
- What is the difference between a flexible liner and a rigid liner?
Flexible liners are easier to install in irregular runs but may be less rigid than rigid liners, potentially affecting draft in long, straight runs. - Can I install a chimney kit through any wall?
Wall compatibility depends on the kit and chimney type. Always match the kit to the pipe size and through-wall clearances specified by the manufacturer. - Are all kits suitable for cathedral ceilings?
Not all kits are designed for cathedral ceilings. Cathedral ceiling kits include components for high clearance and support boxes suitable for vaulted spaces. - Do these kits include all components I need?
Some kits are complete with top plates, caps, and connectors, while others may require additional pipe lengths or fittings sold separately. - What safety features should I look for in a chimney kit?
Look for moisture resistance, airtight seals, gas-tight seams, and rain protection to reduce creosote buildup and leaks. - Is professional installation required for chimney kits?
Large or complex installations, particularly those involving class-A piping or cathedral ceilings, often benefit from professional installation to ensure code compliance and safe venting.
