Selkirk Inc Damper Stovepipe 7In Kit DSP7DK-1

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. When handle is in horizontal position, the damper is ?closed? (reducing combustion). The ?closed? position is still 20 percent open, so the venting system is not completely blocked. When handle is in vertical position, the damper is wide open (no reduction of combustion).
