<p>A gas-fired, simulated log fireplace insert (1) incorporating an automatic flue damper (54) for controlling the operational state of a chimney vent (open/closed) in response to gas combustion, an externally mounted carbon monoxide detector (100) for terminating or inhibiting gas combustion in response to an unsafe level of detected carbon monoxide and a temperature actuated switch (50), disposed within the firebox area (18) of the fireplace (2) proximate the flue (52), for terminating gas combustion in response to excessive fireplace temperatures caused by a malfunctioning damper (54).</p> |
