Mounting the Housing: Existing Construction
1. Determine the desired location for the heater.
2. Drill a small hole through the ceiling at the chosen
location. Stick the end of a coat hanger through the hole
into the attic to help locate the spot in the attic.
3. Check the chosen area from above to make sure that the
wiring can be installed and that the installation will not
interfere with any existing wiring.
4. In the attic, place the housing between ceiling joists at
the chosen location. Mark the ceiling for cutout by using
the heater housing’s flange as a template. Make the
cutout.
5. Install the housing in the opening using hanger bars or
mounting tabs as described above.
6. Remove the desired electrical knockout from the junction
box in the housing.
Ducting
NOTE: All ducting must comply with local building codes.
Vented fans must always be ducted to the outdoors.
1. Make sure you have removed any tape which may be
holding the outlet damper closed. Connect the correct
ducting to the housing collar (4” round outlet on heater
housing).
2. Secure in place using duct tape or a screw clamp. To
ensure maximum air delivery keep the length of duct and
number of elbows to a minimum.
Electrical Wiring (Refer to Fig. 2)
CAUTION: Make sure the power is switched off before
making this installation.
NOTE: All wiring must comply with local and national
codes. You must ground this unit.
NOTE: This unit must be wired on a separate 20 amp
circuit.
You will have to get the heater’s wire compartment cover
from the carton.
1. Run 3 wires and a ground (12GA) from the heater box to
the wall box (location of the switches). Make sure you
identify which wire is for which component. The following
is the colour code in the heater’s junction box: Blue wire =
Fan, Red wire = Heater, White wire = Neutral. Connect the
ground wire to the green ground screw in the heater’s
junction box.
2. Switches should be installed in an approved outlet box.
Make sure you connect the ground in the outlet box as
well.
3. Replace the junction box cover in the heater housing
when the wiring is complete.
Completing the Installation
You will need to get the grill from the carton.
1. Once you have mounted the housing, connected the
ducting, and completed the wiring you can install the
grill. First plug in the fan and heater into the heater’s wire
compartment cover’
3. The heater’s lens flips down, release the lens by pushing
on the 2 tabs which hold it in place in the grill.
4. Secure the grill and lens to the heater housing via 2
screws (provided). Flip the lens back into position.
