Installation Instructions

WARnIng: Wiring procedures and connections should
be in accordance with the National Electric code (NEC &
CEC) and local codes.
!
nOTE: Each heater comes as two packages: the main
heater assembly and the associated grille kit.
CAUTIOn: Do not operate heater without the Grille

!
nOTE: Mount the heater a minimum of 12" (30.5cm)
from the finished floor, and a minimum of 6" (15cm) from any
vertical surface if installed in the ceiling.
Recessed Installation
2. The recess box provided with the heater is designed for
attachment between studs placed on 16" (40.6cm) cen-
tres. If different spacing exists, construct frame to suit
the box in order to avoid any vibration and noise caused
by loose mounting (Figure 2a).
3. Note the orientation of box ("TOP" shown on recess
box) and secure to studs using four holes provided on
side flanges, ensuring these flanges are flush with fin-
ished surface of wall or ceiling (Figure 2b).
Surface Installation

by angling screws through holes provided in rear of
surface box into studs or finished surface.
3. Position recess box into surface box and secure with
four screws provided in parts bag of surface box.
Supply Wiring and Heater Installation
4. Insert approximately 15" (38cm) of supply wire into
recess box through knockout provided in upper left hand
corner (Figure 2b). Wire should be rated for a minimum
of 75°C (167°F)
5. Connect power supply to terminals provided marked L1
and L2. Ground wire should be secured to green ground
screw provided on side of heater assembly (Figure 1).
6. All units are factory prewired for operation with built-in
thermostat. If remote thermostat operation is required
follow appropriate wiring diagram located on inside of
recess box.
!
nOTE: It is recommended that for ceiling mount applica-
tions a remote thermostat be used in order to provide supe-
rior temperature control.
!
nOTE: All wiring must comply with National Electrical
Code and local codes.
7. Secure heater assembly into recess box using the four
M4 screws previously removed.
Front Panel Installation
8. Remove trim frame and front panel (grille) from the
carton.
9. If tamper proof built-in or remote thermostat operation
is required, secure the louvered door to the front panel
using 2 M3 screws (not included) through the holes pro-
vided. The knob can then be removed and adjustment
of the thermostat can be made using needle nose pliers
through the front panel.
10. Install the front panel on the heater assembly. Check to
see that the fan blade is free to turn and that no residue
