IMPORTANT SAFETY INSTRUCTIONS
PET OWNERS WARNING: Health warning for some small pets, including birds,
as they are extremely sensitive to the fumes produced during the first-time use
of many appliances. These fumes are not harmful to humans but we
recommend that you do not use your heater around birds and small pets
during its initial use until the manufacturing corrosion (anti-corrosion)
coatings burn off.

national electrical codes.
NOTE: Compatible with a 240V line voltage double pole wall thermostat. This heater must be
installed by a certified electrician.
: Read and understand all installation and operation instructions prior to
operating this unit. Observe all safety instructions.
1. Use only copper wires rated for at least 75ºC.
2. Heater airflow must be directed parallel to or away from adjacent wall.
3. Observe wall, floor and ceiling clearance requirements.
4. All wiring must be done according to national and local electrical codes in Canada.
The heater must be grounded as a precaution against possible electrical shock. Heater
circuit must be protected with proper fuses.
5. The mounting structure and the anchoring hardware must be capable of supporting
the weight of the heater and the mounting bracket (if used).
6. All electrical power must be disconnected and the main service box, which must be
locked before connecting, inspecting, cleaning or servicing the heater. This is a
precaution to prevent serious electric shock.
7. This heater is not suitable for use in hazardous locations as defined by the national
fire protection association (NFPA) in Canada. This heater has hot and arcing sparking
parts inside. Do not use it in areas where gasoline paint or flammable liquids are used
or stored.
8. This heater is not suitable for use in corrosive atmospheres such as marine
greenhouses or chemical storage areas.
9. The heater must be mounted at least 8 feet above the floor.
Improper installation or failure to follow the procedures outlined in this
instruction manual can result in serious electrical shock.

LOCATING THE HEATER
Install heater out of traffic areas, maintaining clearances stated in figure 1. The direction of
airflow should not be restricted by columns or machinery and the airflow should wipe
exposed walls rather than blowing directly on them. When more than one heater is used in
an area, the heaters should be installed so that the air discharge of each heater supports the
air flow of the others, to provide best circulation of warm air as indicated in figure 2.

INSTALLATION
Hardware needed
You will also need the following hardware, which can be purchased from your local hardware
store or electrical supply store:
Electric wire in the adequate gauge and length for your application;
Proper size fuse or breaker for your heater’s amperage;
Proper wire connectors for your application;
Fasteners appropriate for your application that are strong enough to hold the unit.
Mounting the bracket
Refer to Figures 3a and 3b.
1. Locate a wood stud in the wood ceiling joist. If you cannot locate a wood stud, you have to
install a wood piece on the ceiling as this heater must be securely fastened.
2. Remove the mounting bracket from the heating unit by loosening bracket screws with a
wrench and slipping the handle off over the screw heads.
3. Place a washer on screws before inserting through the holes in the mounting bracket and
screw them securely into a ceiling joist.
NOTE: If you want to swivel the heater either to the right or left adding a washer to both
sides of the bracket is recommended. A longer lag bolt may be required to properlysecure
the unit. See Figure 3a.

HANGING THE HEATER
1) Lift the heater up and into the mounting bracket.
2) Align the bracket screws with the keyhole slots in the mounting bracket.
3) If the heater is to be tilted, it must be positioned in the keyhole slots. (see figure 4).
4) Tighten the bracket screws with a wrench so the unit is securely suspended at
horizontal or vertical level.

ADJUSTING AIRFLOW DIRECTION
1. To turn the unit horizontally when it has been installed with a single lag bolt (as shown in
figure 3a), simply turn the entire heater as needed. (as shown in figure 5 – rotate). The unit
cannot be turned horizontally if it has been installed with 2 lag bolts.
2. To tilt the unit vertically, loosen the bracket screws (see figure 4) and see figure 6 to view
multiple vertical angles.
3. Adjust louvers to the desired position.
NOTE: The louvers are designed so they cannot be completely closed. Do not attempt to
defeat this feature; damage to the unit can result.
NOTE: To prevent possible overheating, please maintain adequate clearance as shown in
figure. 1.

THERMAL CUT-OUT
The heater will automatically turn off should it overheat. When this happens, the red indicator
will turn on. After the unit has cooled back down to a normal level, the heater will turn ON
again and the red indicator will turn off, but the reason of the overheating must be
determined and corrective action must be taken before further operation.
THE HEATER MUST BE TURNED OFF IMMEDIATELY WHEN THE CAUTION
INDICATOR IS GLOWING RED.
NOTE: Whenthe thermalcut-out is activated,the caution indicatorwill turn red. In this
case, immediately turn the heater OFF and inspect for any objects on or adjacenttothe
heaterthatmaycausehightemperatures.
MAINTENANCE INSTRUCTIONS
1. Before cleaning, make sure the power has been turned off at the circuit breaker panel and
the heating element of the heater is completely cool.
2. To maintain the heater’s appearance, it needs only to be wiped over occasionally with a
dry duster. During the summer months, or at other times when the appliance is not in use
and is completely cold, wipe over with a damp cloth. Never allow water to drip into the
heater.
3. Do not use abrasive cleaning powders or furniture polish. Do not use chemical or abrasive
products, metallic scourers and so on, which may deteriorate the surface, to clean the
appliance.
4. During the summer months, or at other times when the appliance will not be used for
extended periods of time, disconnect the power supply and cover the whole appliance with a
dust cloth. Store the heater in a dry and cool place.
5. All other servicing should be performed by qualified service personnel. Do not try to repair
the heater yourself.
