Details show a 3″ x 36″ pipe with Type L vent, UL-641 and UL-103 listed, engineered for pellet and corn burning stoves. Best for mid-length runs requiring UL-listed safety compliance. Choose this when you need a longer, dependable straight section from a trusted brand. Caution: Verify compatibility with your stove’s model and the existing vent adapter when mixing brands.
Selkirk Corp 173036R 3EFC3 Flex Connector
Manufactured in China, easy to use and highly durable. Best for flexible connections around corners or awkward placements where a rigid pipe would be impractical. Choose this if your vent path has tight angles or irregular spaces. Limitation: Flex connectors may have more potential for leaks if not installed with proper clamps and sealant per local code.

This kit provides fresh air to the pellet stove from outside with a 2″ i.d. flex pipe up to 60″ length. Best for improving combustion air when room air venting is insufficient. It includes a wall plate screen and clamps. A good complement to venting when indoor air supply is limited. Caution: Verify that the outside air kit is compatible with your stove’s air intake design and local building codes.
Buying Guide
Key considerations for selecting pellet stove vent pipe:
- Vent path length: Shorter runs favor rigid sections; longer runs may benefit from longer or flexible sections.
- Wall penetration: Horizontal installations require a wall thimble, termination cap, and appropriate clearances.
- Material and durability: Stainless steel inner walls resist corrosion and heat better than basic metals over time.
- Code compliance: UL listings and model compatibility with 3-inch systems are essential for safety.
- Installation complexity: Complete kits simplify setup; modular pipes offer customization but may require additional fittings.
Frequently Asked Questions
- What size is standard for pellet stove vent pipes?
Most standard pellet stove vent systems use 3-inch pipe for the exhaust path.
- Should I use a flex connector or rigid pipe?
Rigid pipe provides a cleaner seal and fewer leak points; flex connectors are helpful for tight turns or non-standard layouts.
- Is UL listing important for vent components?
Yes, UL listings indicate compliance with safety standards for venting pellet stoves.
- Can I mix brands for a vent run?
Mixing brands is possible but ensure parts are compatible and fit securely to maintain a proper seal.
- Do fresh air intake kits affect venting performance?
Fresh air intake kits improve combustion when indoor air is restricted, potentially affecting stove efficiency.
- What maintenance does a pellet vent require?
Regular inspection for corrosion, seal integrity, and clearance to combustibles is recommended.
