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

installed.

Remove the main heater assembly from the carton. Re-1.
move the screws securing heater assembly and retaining
brackets to the recess box and separate. (Figure 1) .

!

NOTE: Mount the heater a minimum of 12” (30.5cm)

from the nished oor, and a minimum of 6” (15cm) from any

vertical surface if installed in the ceiling.

Recessed Installation

The recess box provided with the heater is designed for 2.

attachment between studs placed on 16” (40.6cm) cen­tres. If different spacing exists, construct frame to suit

the box in order to avoid any vibration and noise caused
by loose mounting (Figure 2a).
Note the orientation of box (“TOP” shown on recess 3.
box) and secure to studs using four holes provided on
side anges, ensuring these anges are ush with n­ished surface of wall or ceiling (Figure 2b).

Surface Installation

2. Secure optional surface mount box (Part No. RFP8D)
by angling screws through holes provided in rear of

surface box into studs or nished 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

Insert approximately 15” (38cm) of supply wire into 4.
recess box through knockout provided in upper left hand
corner (Figure 2b). Wire should be rated for a minimum

of 75°C (167°F)

Connect power supply to terminals provided marked L1 5.
and L2. Ground wire should be secured to green ground
screw provided on side of heater assembly (Figure 1).

All units are factory prewired for operation with built-in 6.
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 applica­tions a remote thermostat be used in order to provide supe­rior temperature control.

!

NOTE: All wiring must comply with National Electrical
Code and local codes.

Secure heater assembly into recess box using the four 7.

M4 screws previously removed.

Front Panel Installation

Remove trim frame and front panel (grille) from the 8.
carton.

If tamper proof built-in or remote thermostat operation 9.

is required, secure the louvered door to the front panel

using 2 M3 screws (not included) through the holes pro­vided. The knob can then be removed and adjustment
of the thermostat can be made using needle nose pliers
through the front panel.

Install the front panel on the heater assembly. Check to 10.
see that the fan blade is free to turn and that no residue
remains in the unit. Front panel can then be secured to

assembly using four M4.8 x 37 screws provided.

Follow the steps as shown in Figure 3.11.

Operation and Maintenance

Set thermostat to desired temperature and both fan and 1.
heat should come on. Note that when desired tempera­ture is reached the fan operation will continue for a short
period after the elements have de-energized in order to
remove residual heat from the unit.

The fan motor is permanently lubricated, sealed at the 2.
factory and is maintenance free.

It is suggested that at the beginning of each season the 3.
front panel is removed and the wire connection condition
is checked and the unit is cleaned of dust and dirt with a
vacuum cleaner.

!

NOTE: Always open the circuit breaker to disconnect
power to the unit prior to performing any maintenance or
service operation.

WARNING: Should the Over Temp light come on, discon-

nect power to the heater or turn down the thermostat fully
counterclockwise and call a licensed electrician. DO NOT
USE HEATER UNTIL THE CAUSE OF THE PROBLEM IS
DETERMINED AND FIXED.
