Operational Reliability: Essential for preventing high flue temperature lockouts and ensuring optimal heat exchanger performance

When your heater throws a diagnostic code—typically a one-flash or two-flash LED signal on the integrated control board—it often indicates a failure in the combustion air proofing circuit

Burnham Boiler 8116324 Vent Damper 30067439-890 This is a 1/8 HPThe Burnham Boiler 8116324 7" Vent Damper is a critical automatic fuel saving component designed for atmospheric gas fired boilers. This motorized vent damper functions by closing the flue pipe during the furnace's off cycle, preventing residual heat from escaping through the chimney. Engineered for seamless integration with Burnham heating systems, this unit features a redundant safety switch to ensure the burner only fires when the damper is in the
