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.
