Field Controls 70009800 GMA-AL GVD Vent Damper Motor Assembly, Metal Base, 24 Vac

The Field Controls 70009800 (model GMA-AL) is a GVD vent damper motor assembly with a metal base. It is a replacement damper motor, also called a vent damper actuator, for Field Controls GVD automatic vent dampers on gas-fired appliances.

Key Features:

• Model GMA-AL GVD vent damper motor assembly
• Metal base
• 24 Vac operation
• Motorized actuator that opens and closes the vent damper to control flue exhaust flow

A vent damper motor like this one opens the damper while the appliance runs and closes it during off cycles. Closing it helps limit heat loss up the vent when the burner is idle.
