摘要： A motor/damper assembly installable on the top end of a fuel-fired water heater includes a support plate structure upon which a flue collar with a pivotally supported flue damper, a drive motor, and a drive shaft interconnecting the motor damper are mounted. The assembly is installed by placing the collar over the upper end of the water heater flue, securing the support plate structure to the top end of the water heater, and positioning a top cover housing on the support plate structure. Using the assembly provides improved support rigidity and alignment for the motor and shaft relative to the damper, improved repeatable precise manufacturing placement of the motor and shaft, improved construction aesthetics, with the cover also protecting the shaft from shipping and handling damages.
