Abstract:
A damper-controlled gas supply system for a fireplace having a firebox and a chimney vent communicating with the firebox, the system comprising:a burner inside the firebox; a solenoid valve controlling a flow of inlet gas to the burner; a damper mounted inside the fireplace chimney vent above the firebox, the damper being selectively positionable to open or close the fireplace chimney vent; a control rod connected to the damper above the firebox, the control rod being accessible to a user and manipulable between first and second positions corresponding to closed and open damper positions, respectively; an electrical switch cycling the solenoid valve between off and on positions, the on position permitting the flow of gas to the burner; and a wire linkage disposed outside the firebox and connecting the control rod to the electrical switch, the linkage producing movement of the electrical switch to cycle the solenoid valve between the off and on positions in response to manipulation of the control rod between the first and second positions, respectively.
