TO INSTALL FAN DECK ASSEMBLY
NOTE: Fan deck assembly should not be installed until after the
drywall phase of construction is complete. Dust from drywall
installation and joint compound can be harmful if it gets inside
fan deck components.
1. Locate fan deck and mounting rails in top of back box.
2. Insert flanges on fan deck into mounting rails and slide back
until fan deck stops (see Figure 6).
3. Make wiring connections, attaching one red and one black
thermostat lead to two (2) black heater leads for 240V or to
black and white heater leads for 120V with wirenuts (provid-
ed). Connect field ground lead to bare ground wire with
wirenut (provided). See Figure 7.
4. Remove 1/2” knockout from grille and install grille using two
oval head screws. Push thermostat knob on thermostat shaft.
5. Reconnect power at main fuse or circuit breaker distribution
panel.
TO CHANGE WATTAGE OUTPUT
The chart shows the wattages available by model. Each heater is
factory wired for its maximum wattage. The last two columns in
the chart refer to the jumpers on the CLIP ‘n’ Fit
®
Board. To change
wattage, clip out Jumper 1 and/or Jumper 2 as shown in the chart
below. Completely remove jumpers by clipping at both ends as
close to the board as possible (See Figure 8).
