APPLICATION

The D896 Automatic Vent Damper is a 24 Vac, motorized
stack damper. The damper closes off the furnace or boiler
stack during the heating off-cycle. Use the D896 only on
Underwriters Laboratories Inc. listed and American Gas
Association design certified atmospheric type, gas-fired
furnaces and boilers. The furnaces or boilers must be
equipped with a draft hood that has an outlet area no larger
than the damper inlet area. Do

not use with oil-fired furnace

or boiler, power burner, or direct vent furnace or boiler.
