- Used to connect a single or Double Wall Stove Pipe to an existing masonry chimney
or a relined masonry chimney with stainless steel liner.
DAMPER KIT
- Allows the operator to alter the amount of air drawn through the venting system,
controlling the stove’s combustion.
- Must be installed directly on the stove’s flue outlet where applicable.
- When handle is in horizontal position, the damper is “closed” (reducing combustion).
- The “closed” position is still 20% open, so the venting system is not completely blocked.
- When handle is in vertical position, the damper is wide open (no reduction of combustion).
