Abstract
A damper system comprises a damper blade having open and closed states. The damper blade is movable in a linear direction only between the open and closed states. The damper blade may fully overlap with a flue passage in the closed state, and the damper blade may lack any overlap with the flue passage in the open state. A portion of the damper blade may directly contact a switch activation arm in the open state, wherein the switch activation arm confirms the open state of the damper blade.
