Abstract
A damper mechanism for a gas-fired appliance is disclosed. The damper mechanism is mechanically operated in response to changes in pressure within a portion of the appliance. Changes in gas pressure operate to displace a diaphragm, thereby moving a linkage attached to a flue damper, such that the damper can be moved between open and closed positions. An interim damper control activation arm can pivot in response to movement of the linkage to actuate electrical switches, which act to close a magnetic pilot valve when the damper is in a partially-opened or partially-closed position.
