Buying Guide: Key Decision Points For Corner Pellet Stove Venting
What should you consider when choosing a corner vent elbow?
- Diameter compatibility: Most pellet vents use 3 inches; verify the exact size for your system.
- Angle range: Fixed 90-degree elbows are simple; adjustable elbows save space in tight corners.
- Material and temperature tolerance: Carbon steel and other alloys influence durability and heat resistance.
- Installation method: Slip-fit designs simplify assembly; some require screws or clamps for a secure seal.
- Maintenance access: Clean-out tees provide easier access for sweeping the vent line.
