PPLIANCE WIRING 
1.  To locate the vent damper wire harness (if supplied) receptacle on 
the appliance, refer to the appliance manufacturer instruction 
manual and follow accordingly. (See Figures 5,6,7) 
2.  The wire harness shall be securely fastened thru the conduit 
bracket, located on the vent damper motor assembly. 
3.  The GVD series vent damper must be electrically connected with 
appliance burner control circuit. 
4.  Be careful not to allow the wire harness to come in contact with 
hot surfaces. Stand off brackets may be required to prevent 
contact to hot surfaces. 
NOTE: Plug in control circuits may contain internal fuses. A vent 
damper connected to an appliance with a fused control circuit will not 
allow the burner to operate unless the vent damper is connected. 
NOTE: Internal fuse blow after the first complete cycle.

NSTALLATION ON EXISTING APPLIANCES 
This procedure is intended as a guide to aid in safely installing an electrically operated automatic vent damper device on an 
existing appliance so that the modified appliance will continue to operated safely and satisfactorily. 
This procedure is based on the assumption that the history of the specific appliance has been one of safe and satisfactory 
operation. 
This procedure is predicated on central furnace, boiler and water heater installations, and it should be recognized that generalized 
procedures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to 
determine safe operation of the equipment.
