Lochinvar & A.O. Smith 100208806 Flu Damper

The Lochinvar & A.O. Smith 100208806 Flue Damper is a 6-inch diameter automatic vent damper designed for high-efficiency water heaters and boilers. This OEM replacement part is essential for minimizing standby heat loss by closing the flue pipe during the appliance's off-cycle, significantly improving overall system performance. Engineered for precision, the unit includes an integrated actuator and a dedicated wire harness to facilitate a direct interface with the equipment's 24V control circuit. This specific assembly is a drop-in replacement for legacy part numbers FLD1016 and FLD1016K, as well as several Effikal RVGP series models.

Constructed with heavy-duty materials to withstand high-temperature exhaust environments, the 100208806 flue damper assembly features a clockwise rotation and requires a minimum 6-inch clearance from combustible materials. For technicians servicing Lochinvar Charger or A.O. Smith BTR series units, this 24V flue damper ensures the safety interlock—verifying the damper is in the fully open position before allowing the main burner to ignite—is maintained. Utilizing genuine HVAC replacement parts like the 100208806 helps prevent the backflow of combustion fumes and maintains the certified mechanical integrity of the venting system.

Key Benefits
