Isokern Maximus Linear Series Gas Fireplace
Enervex MFD & RS Chimney Fan - Installation Instructions
1.
Before installing the MFD on the chimney, a power cable
should be wired to the actuator and the actuator cover
should be secured.
2.
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.
3.
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.
4.
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.
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.
WIRING OF A GAS FIREPLACE WITH A DAMPER
6.
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
Figure 27
.
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 end
switches should connect to the damper prove terminals
(16 and 17).
8.
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.
9.
If the damper does not operate correctly when power is
supplied or if it rotates the wrong direction, verify wiring as
shown in
Figure 35
of this manual.
