GVD Series Vent Damper
Improves Gas Boiler Efficiency. Keeps Cold Air Out, Warm Air In.
The Field Vent Damper works automatically to allow natural draft
during appliance operation while preventing residual appliance heat
and conditioned air from escaping during off cycles. It also prevents
the infiltration of cold air during down drafts. It’s made of stainless
steel and is available in 8 sizes, 4" through 12".

in the open position. This unit will not interfere with existing appliance
safety controls, when properly installed.
