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.

GENERAL SAFETY INFORMATION
: This heater requires a hardwire installation (no plug). The installation of
this product must be carried out by a certified electrician and in accordance with all local
and national electrical codes.
NOTE: This appliance is compatible with a 240V line voltage single pole wall thermostat
(not included). 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 at all times.
1. Use only copper wires rated for at least 60ºC.
2. Heater air flow 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 the
United States and 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 the United States. 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. This 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 3. The direction of air flow
should not be restricted by columns or machinery and the air flow 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 in a way 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 4.

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 5
1. Locate a wood stud in the wood ceiling joist. If you cannot locate a wood stud, you must
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.
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 6.
4) Tighten the bracket screws with a wrench to secure the unit once suspended
at horizontal or vertical level.
ADJUSTING AIR FLOW DIRECTION
1. To tilt the unit vertically, loosen the bracket screws (see figure 6) and see figure 7 to
view multiple vertical angles.
2. 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 3.

OPERATING INSTRUCTIONS
Note: After setting an external thermostat to control the heater, the power
selection switch on the unit will be the only working function on the heater itself.
TO PROTECT THE HEATING ELEMENT
This unit has a fan delay function to provide warm air when it is first turned on. When
the heater is turned off, the fan will continue working for a short while to cool the
heating element; then the fan will automatically turn off. This feature helps maximize
the heater’s life.
WARNING: the heater must be properly installed before it is used.
SETTING THE THERMOSTAT
1) Rotate thermostat knob clockwise to its highest position; the amber POWER
INDICATOR will turn on.
2) Once the room reaches your desired comfort level, rotate thermostat knob counter-
clockwise until a click is heard, then rotate it slightly clockwise.
Your heater will now cycle on and off to maintain your set room temperature.
POWER SELECTION SWITCH
Using the SELECTION SWITCH, select the heating
output: I for 10000W, II for 15000W

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: When the thermal cut-out is activated, the caution indicator will turn red. In this
case, immediately turn the heater OFF and inspect for any objects on or adjacent to the
heater that may cause high temperatures.
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 appearance of the heater, 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, it can be cleaned by wiping it
with a damp cloth. Do not let water drip inside the heater.
3. Do not use abrasive cleaning powders or furniture polish to clean this appliance.
Do not use chemical or abrasive products, metallic scourers and similar items;
they may deteriorate the surface.
4. During the summer months, or at other times when the appliance is not in use,
disconnect the power supply, and cover the whole appliance with a dust cloth.
Store the appliance in a dry and cool place.
5. All servicing should be performed by qualified service personnel. Do not try to
repair the heater yourself.
