Connecting The Room Sensor As A Return Air Sensor - Harman Accentra Installation & Operating Manual

7. If the room sensor is used as a return air sensor
rather than a room thermostat/sensor, the black cable
will not be used. The room sensor itself (gray or black
cable with black and red wires) will be connected to the
blue twisted wires from the control board.
Note: The stove body must be able to slide out of the
shell to the limit of the power cord wires for cleaning and
service. Therefore, if the room sensor is connected as
a return air sensor, the wire should be connected long
enough to allow this, but not too long that it would get
tangled or pinched anywhere.
Notice: The male/female connections between the
mounting shell and the stove body should always be
maintained. Wirenut or taped splices should never be
used.

Connecting the room sensor as a return air sensor

• Insert the sensor end of the wire from the rear of the
mounting frame through the hole as shown in fig. 24 .
• Wire-tie the sensor end so that the sensing tip is in
the middle of the front return air opening. See Fig. 25.
• Wire-tie the sensor wire to the inside of the mounting
frame up to the cord grounding location. Follow the
power wiring to where you make the male/female
terminal connection to the twisted blue wires.
There are (2) crimp-on connectors in the hardware pack
that must be installed on the internal ends of the room
sensor wires.

8. Install the (4) 3/8-16 x 1" leveling bolts into the
threaded holes in the bottom pan of the mounting shell.
The front two leveling bolts may not be necessary, but
the back two will need to be used to level the wing so
that it is flush with the fireplace face. See Fig. 26

9. Install the completed frame/surround assembly into
the firebox and level/plumb the wing to the fireplace
face using the leveling bolts as jacks.
If needed, the installed HCS ¼-20 x 1 Z5 bolt can be
used to adjust the squareness of the stove body in the
cage.
