Diagram #8A5: Forced Air Furnace having a Combustion Air Supply Duct and also a Replacement Air Supply Duct that provides additional air for a 120Vac Gas Dryer and for the normal operation of the home.
- Combustion Air Damper (HOM-0x12-SF2) for two appliances
- 24Vac Relay Adaptor with a Duplex Receptacle and a Red Light on/off Switch (RADP-0241-S10A) to function as a control center interlocked to120Vac supply for a plug-in type Gas Dryer
- Replacement Air Control Damper (Power Open) HAC-0x10- OPO (‘x’= diameter of Duct)
OPERATION:
- Combustion Air Damper is interlocked to open for Furnace firing and/or interlocked to open for Dryer operation
- The Gas Dryer is plugged into the Adaptor RADP-0241-S10A receptacle and will operate only after the Red Light Switch is turned on and the Combustion Air Damper is in the open position
- The HAC-0x10- OPO (Power Open) Damper will open and close simultaneously with the Combustion Air Damper. When the Dryer has completed its cycle, the Adaptor Red Light Switch is to be turned off allowing the Combustion Air Damper and the Replacement Air Damper to close
Note: Manual setting of the Furnace Fan does not affect the Combustion Air Damper operation.
This installation does not interfere with the operation of the Air Conditioner.
