1. PRODUCT INFORMATION
1.1 FUNCTION
The ENERVEX MFD is a low profile, automated fireplace
damper. It is for use in conjunction with an ENERVEX
ADC100 control and RS model chimney fan as part of the
EcoDamper System. or with an ADC150 control and and
RS model chimney fan as part of the IntelliDraft System. It
prevents excess heat from escaping through the chimney
when the fireplace is not in use.
The MFD is designed for chimney top installations and is for
use with gas fireplaces only.
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 or ADC150
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.
The actuator has two endswitches to prove damper position
(open or closed) and is equipped with the Enerdrive fail safe
system to open the damper in the event of an electrical or
mechanical failure.
The damper is rated for temperatures up to 575oF (300oC).
The damper is sized to provide sufficient clearance between
the damper blade and the fan inlet when open.
The MFD is constructed of 18 gauge, type 304 stainless
steel.
System installation must conform to the requirements of the
authority having jurisdiction. When required by the authority
having jurisdiction, the installation must also conform to the
NFPA31, NFPA54 or NFPA211.
All electrical wiring must be in accordance with the
requirements of the authority having jurisdiction or, in
absence of such requirements, with the National Electric
Code, NFPA 70.
1.2 SHIPPING
Damper, actuator, cover and hardware are shipped as a unit.

3. MECHANICAL INSTALLATION
3.1 ACTUATOR AND COVER
Before installing the MFD on the chimney, a power cable
should be wired to the actuator (See Ch. 4) and the actuator
cover should be secured.
Use 4-conductor cable (min. 18 AWG) with a weatherproof
jacket such as rubber or silicone. Install a weatherproof cable
connector on the side of the actuator cover to prevent water
ingress to the actuator.
Use (6) of the included sheet metal screws to secure the
actuator cover to the MFD. Once secure, apply a bead of
silicone around the seams of the cover.

3.2 LOCATION
Mount the MFD outdoors at the top of a steel chimney. Slide
the collar of the MFD into the steel chimney until the damper
rests on the stop flange. Sheet metal screws may be installed
around the collar into the chimney for additional support.
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.

4. ELECTRICAL INSTALLATION
4.1 GENERAL
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 90o (MFD will open). Verify settings of the
actuator before wiring.
Verify voltage of actuator before connecting
to a power supply. Acuator will run on either
120VAC or 24VAC.!
DANGER
Turn off electrical power before servicing.
Contact with live electric components can cause
shock or death.

4.2 WIRING OF A GAS FIREPLACE WITH A DAMPER
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 in Fig.6. When used with
an IntelliDraft System, the RS Chimney Fan and MFD will
interlock with an ADC150 control as shown in Fig. 7.
Power to the actuator must be supplied externally. Interlock
the damper with the control board via terminals 14 and 15
as shown below and on the next page. The Normally Open
and Common terminals of the actuator endswitches should
connect to the damper prove terminals (16 and 17).
Complete system wiring details are shown in the ADC100
and ADC150 Control Installation Manuals.

5. STARTUP AND CONFIGURATION
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 90o in the clockwise (CW) direction.
If the damper does not operate correctly when power is
supplied or if it rotates the wrong direction, verify wiring as
shown in Ch. 4 of this manual.
5.2 SEQUENCE OF OPERATION
See Ch. 5 of the ADC100 Control Installation Manual for the
sequence of operation of the EcoDamper System.
See Ch. 5 of the ADC150 Control Installation Manual for the
sequence of operation of the IntelliDraft System.
6. MAINTENANCE AND TROUBLESHOOTING
6.1 CLEANING
Clean the MFD periodically at the same time the fan and/or
chimney are cleaned.
Damper should be cleaned with a cloth or rag. Check for and
remove any debris that may be blocking the damper opening
or chimney.
