Diagram #8A6: Forced Air Furnace and a 120Vac Gas Dryer that has a separate Fresh Air Duct for its operation.
- Fresh Air Damper with Relay and End Switch MAC-0x11-SPC ( Power Close).
- 24Vac Relay Adaptor with a Duplex Receptacle and a Red Light (on/off) Switch RADP-0241-S10A
OPERATION:
- The MAC Damper is to be open before the Dryer operates. It is interconnected to the Furnace for power or to a separate 24Vac Transformer and to the Adaptor RADP-0241-S10A
- The RADP-0241-S10A is plugged into a regular 120Vac Receptacle and the Gas Dryer is plugged into the RADP-0241-S10A Receptacle
- Manually turning on the Red light Switch opens the MAC Fresh Air Damper and closes the End Switch to turn the red light on. The Damper is thus proven to be open (interlocked) ready for the Dryer to run
- After the Dryer cycle is complete, the Red Light Switch may be turned off causing the Damper to close
Note: This installation does not interfere with the normal operation of the heating or cooling cycles of the Furnace.
