GAS VENT DAMPER
Model:
GVD-4 through 12
Field Controls (GVD) gas vent damper was developed to reduce off cycle venting losses through boilers and
draft hoods. When the boiler is in the standby mode heat escapes up the chimney. The heat comes from the
boiler and the condition space. To significantly reduce these losses install a Field Gas Vent Damper. The
damper is installed between the vent or chimney and as close to the draft hood as practical. When properly
installed the damper opens before the burner fires and closes after the burner shuts off. The electrical
circuits in this product are designed not to override the existing limit and safety controls of the boiler.
CAUTION
The plug is installed only if the
appliance is equipped with an intermittent or direct
ignition system. Failure to follow these instructions can
cause odor problems and minor property damage due
to moisture. Do not install on standing pilot systems.
