FireSafe Flexible Chimney Liner Insert Kit — 6″ x 15 ft
Material and construction: Premium 316 stainless steel with 7-ply seams and 10 corrugations creates a gas- and watertight barrier. This helps prevent chimney fires and carbon monoxide leaks while maintaining structural integrity. Best for replacements or new installs where durability matters.
Complete kit for installation: Includes a 13″ x 13″ top plate with a rain cap, a .006″ thick liner, and an appliance connector for vertical hookups. This all-in-one package supports moisture resistance and reduces the risk of corrosion and costly repairs.
Performance benefit: Engineered to improve draft and overall efficiency of wood stoves, fireplaces, and furnaces. Expect reduced creosote buildup and improved heating performance.
Who it’s best for: Homeowners replacing old liners or installing a new insert in solid-flue systems that need robust durability and a straightforward vertical installation.
Limitations: The kit emphasizes vertical installations; horizontal runs may require additional adapters or configurations. Always verify your flue diameter and installation angles.
FireSafe Flexible Chimney Liner Kit — 6″ x 15 ft with Tee Connector
Material and construction: Premium 316L stainless steel for maximum durability and safety. The liner features 7-ply seams and 10 corrugations, delivering a gas- and watertight barrier to reduce leaks and prolong liner life.
Complete kit for easy installation: Includes a 13″ x 13″ top plate with a rain cap, a .006″ thick liner, and a tee connector for horizontal hookups. This supports moisture resistance and prevents costly repairs.
Performance benefit: Engineered to enhance airflow and combustion, lowering creosote buildup and raising heating efficiency for wood stoves and gas/pellet inserts alike.
Who it’s best for: Installers needing a tee connector to route the liner horizontally or into side vents while maintaining a robust moisture barrier.
Limitation: Horizontal configurations may require precise alignment; confirm clearance and roof routing before purchase.
FireSafe Flexible Chimney Liner Insert Kit — 3″ x 20 ft
Material and build: Premium 316 stainless steel designed for durability and safety, with 7-ply seams and 10 corrugations to form a gas- and watertight barrier. This helps minimize leaks and maintains long-term structural integrity.
Complete kit: Includes top plate with rain cap, a .006″ liner, and installation accessories. Suitable for smaller diameter flues and retrofit projects where space is constrained.
Performance benefit: Improves draft and heating efficiency for compact stoves and fireplaces, supporting cleaner, more efficient burns.
Who it’s best for: Homeowners working in tight spaces or with smaller flue diameters that still require a full-featured liner kit.
Limitations: The 3″ diameter may not fit all standard stoves; verify flue size and deck clearance before ordering.
FireSafe Flexible Chimney Liner Kit — 3″ x 20 ft with Tee Connector
Material and build: Premium 316L stainless steel with 7-ply seams and 10 corrugations ensures a durable, gas- and watertight liner. Long-term structural integrity is a priority for this kit.
Complete kit: Includes a top plate with rain cap, a .006″ thick liner, and a tee connector for horizontal hookups. This makes mid-size installations straightforward and moisture-resistant.
Performance benefit: Designed to optimize airflow and combustion, reducing creosote buildup while improving heating performance for wood-burning stoves and compatible inserts.
Who it’s best for: Projects requiring a tee-connected horizontal route in smaller flue systems where a full kit is advantageous.
Limitation: As with other horizontal configurations, precise routing is required; check roof access and clearance before purchase.
6 Inch Chimney Cap Cone Top with Screen
Protection and ventilation: A 6-inch round cap helps keep leaves, rain, snow, and small animals from entering the chimney pipe while maintaining airflow. This supports cleaner, safer operation for exterior venting.
Construction: Made from galvanized steel for corrosion resistance and durability in outdoor conditions. Designed to fit 6″ outside diameter flue pipes and single fireplace pipes.
Who it’s best for: Homeowners needing exterior cap protection without compromising draft or ventilation. Not suitable for double-wall chimneys.
Limitation: Not compatible with double-pipe setups; verify your system’s configuration before purchasing.
Buying Guide: Key Purchase Considerations
- Flue diameter compatibility: Measure your flue to choose 3″ or 6″ liners and avoid mismatches that can cause drafting issues.
- Vertical vs. horizontal routing: Tees enable horizontal connections, but horizontal runs require careful planning for fit and clearance.
- Material and durability: Stainless steel (316 or 316L) offers higher corrosion resistance and safety for long-term use, especially in creosote-prone environments.
- Complete kit contents: Look for top plates with rain caps, liners, and connectors to ensure moisture resistance and ease of installation.
- Cap protection: Exterior caps protect the chimney but ensure compatibility with your cap size and roof type; avoid caps that block necessary airflow.
- Local codes and permits: Confirm with local authorities whether a liner kit or chimney cap requires inspection or permits in your area.
Frequently Asked Questions
- What size liner should I choose for a typical wood stove?
– Most standard wood stoves use a 6″ liner, but some smaller stoves or retrofit projects may need 3″ liners. Always verify your flue diameter. - Do liner kits include all installation parts?
– Many kits offer top plates, rain caps, and liners, with tees included for horizontal routing. Check product details to confirm. - Are stainless steel linings risky with creosote?
– Stainless steel liners are designed to resist creosote buildup and corrosion better than basic metal liners, improving safety and efficiency. - Is a chimney cap necessary?
– A cap protects the chimney from debris and animals, while allowing airflow; it’s recommended for exterior venting but ensure proper sizing. - Can I install a liner myself, or should I hire a pro?
– Installation can be DIY with a complete kit, but professional installation is advised for complex horizontal routing or high-risk setups.
