- Page 3 The MFD is designed for chimney top installations and is for use with gas fireplaces only. Function The MFD is powered by a 120 or 24 VAC actuator. The actuator is interlocked to the control so it only operates when the fireplace is in use and the fan is running. When there is a call for heat from the fireplace, the ADC100 control begins its operational sequence to open the damper and start the chimney fan. Once the damper opens and there is sufficient draft in the chimney, the control releases the gas valve for fireplace operation.

- Page 5 Once the MFD is secured, place the RS fan on the adapter. Use the mounting holes on the fan base as a drill template to make one mounting hole in each corner of the adapter. Use bolts and locking nuts to secure the fan to the MFD.
- Page 6 Wire that actuator for 2 wire/ 2 position operation as shown in Fig. 4 (120 VAC) and Fig. 5 (24 VAC) below. The actuator should be set for clockwise (CW) rotation and should fail to 90 (MFD will open). Verify settings of the actuator before wiring.
- Page 7 4.2 Wiring of a Gas Fireplace The MFD must be interlocked to an ENERVEX control. When used with a gas fireplace as part of the EcoDamper System, both a RS Chimney Fan and MFD will interlock with the ADC100 control as shown below. Power to the actuator must be supplied externally. Interlock the damper with the control board via terminals 27 and 28 as shown below. The Normally Open and Common terminals of the actuator endswitches should connect to the damper prove terminals (29 and 30).
- Page 8 5.1 Set-Up Once the MFD has been installed, verify operation and rotation of the damper. The end of the damper rod is notched to indicate position of the damper blade. As the actuator opens the damper, the notch will indicate movement from 0 to 90 in the clockwise (CW) direction.
