SAVE THESE INSTRUCTIONS

OPERATING INSTRUCTIONS

The heater must be properly installed before it is used.

Turn the power on to an appropriate circuit breaker for the maximum power of the heater on the electrical panel, referring to the nameplate of the heater.

CONTROL:

• Model with built-in thermostat: Refer to the OPERATING INSTRUCTIONS OF THE THERMOSTAT section of these instructions.
• Model without built-in thermostat: Maintains room temperature by a line-voltage wall thermostat approved for inductive loads (not supplied). A power of 750W or 1500W is available when installing the heater.

Note: A pulsing electronic thermostat must not be used with this model. Electronic thermostats must be in FAN mode.

MAINTENANCE INSTRUCTIONS

• Once every quarter, remove the front cover and use a vacuum cleaner to remove the dust accumulation inside the heater.
• Cleaning should be done while the heater is disconnected from the main service panel. Wait until the housing and heating element cool before performing maintenance.
• Replace the front cover before energizing.
• A qualified technician should perform any other servicing.

INSTALLATION INSTRUCTIONS: RECESSED OR SURFACE MOUNTING STEPS

CAUTION:

High temperature, risk of fire, keep electrical cords, drapery, furnishings, and other combustibles at least 36 in. (915 mm) from the front of the heater and away from the sides and top.

WARNING:

To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.

Mounting Steps:

1. Use the template provided with the heater.

   a) Recess wall mounting

   • Provide a minimum opening of 2 5/8 in. (67 mm) deep. HOLE MUST BE CUT PRECISELY.
   • Use the template provided to cut the wall opening. The bottom of the unit must be at least 6 in. (152 mm) from the floor and 2 in. (51 mm) from the adjacent walls.
   • Recommended installation height is 12 in. (305 mm) from the bottom of the unit for better temperature regulation.

   b) Surface wall mounting

   • The bottom of the unit must be at least 6 in. (152 mm) from the floor and 2 in. (51 mm) from the adjacent walls.
   • Recommended installation height is 12 in. (305 mm) from the bottom of the unit for better temperature regulation.
   • Locate positionning of the supply wire and make a 1 in. (25 mm) diameter hole. Firmly install the 3 screws supplied to the wall. DO NOT OVERTIGHTEN SINCE YOU WILL NEED TO SLIDE THE HEATER AT STEP 6.b).
2. Remove the front cover by unscrewing the screw in the air outlet (at the bottom) and by sliding the front cover upwards.
3. Disconnect the thermostat from the casing by pulling the white plastic connector (model with built-in thermostat) and place the front cover on a clean surface.
4. Remove the connection box cover. Remove the appropriate knock-out from the box for the electrical supply.
5. Wire the heater according to national and local codes and as per the wiring diagram below.
6. Installation:

   a) Recessed wall mounting

   Install the casing in the wall opening using the holes located on the edge on each side of the recess box.

   b) Surface wall mounting

   Align the oversized part of the holes with the screws already on the wall, then slide the heater downward. Make sure that the 3 screws are well supported at the top of the keyhole (small part). Once the heater is in place, finish tightening the 3 screws.

7. Reconnect the thermostat to the casing by clipping both parts of the white plastic connector together. Replace the flat cable in the wire clip.
8. Put the connection box cover back.
9. Reinstall the front cover by inserting the 2 tabs located at the top of the front cover into the 2 slots located at the top of the casing, then tighten the screw located in the air outlet. Important: make sure the front cover is properly seated and secure to the casing.
10. Test the heater. (The model with built-in thermostat starts with a calibration sequence).
    • Adjust heater thermostat at maximum setting. A slight heating smell may emerge from the openings, which is normal and will stop after a few minutes of operation.
    • Adjust thermostat at minimum setting.
