AUTOMATIC DAMPER ADAPTOR  
Model: ADA-1 
The ADA-1 Automatic Damper Adapter is intended for use with boilers and water heaters having a 24V automatic vent or 
flue damper.  The ADA-1 simplifies the control wiring connections to Field Controls combustion air/venting equipment by 
using the appliance’s damper control cable.  The appliance’s damper cable is simply plugged into the ADA-1’s 
corresponding receptacle, and the ADA-1’s damper cable is plugged into the damper’s receptacle instead.  The ADA-1’s 
control cable is then connected to the combustion air/venting equipment’s three control terminals.  The three control 
terminals and the control cable’s three corresponding terminals are clearly and identically marked for easy, foolproof field 
connection. 
Upon a call for heat, the appliance’s burner control circuit sends out a call for heat to the automatic damper, which must 
open before allowing the burner to fire.  This call for heat is intercepted by the ADA-1, and sent to the combustion 
air/venting equipment first.  The combustion air/venting equipment will then activate, and upon closing of the safety switch 
(or switches) built into the combustion air/venting equipment, the call for heat is then sent on to the automatic damper.
