GENERAL SAFETY INFORMATION
WARNING: This heater requires 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.
Read and understand all installation & operation
instructions prior to operating this unit. Observe all safety instructions.
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 all wall, floor and ceiling clearance requirements.
4. All wiring must be done according to national and local electrical codes.
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 at the main service box, which
must be locked before connecting, inspecting, cleaning or servicing the
hater. This is an important precaution to prevent serious electric shock.
7. This is heater is not suitable for use in hazardous locations containing
explosive liquids or vapours. This heater has hot or arcing or sparking
pads inside. Do not use it in areas where gasoline, paint or flammable

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 off the floor. For specific
clearances, please see next page.
Improper installation or failure to follow the procedures
outlined in this instruction manual can result in serious electrical shock.
LOCATING HEATER
Install heater away from traffic areas, maintaining clearances stated in figure 2
(below). The air flow direction should not be restricted (ie. by columns or
machinery). The air flow should wipe exposed walls rather than blowing
directly on them. When more than one heater is used in an area, heaters
should be installed so that the air discharge of each heater supports the air
flow of the others, to provide best warm air circulation as shown in figure 3.

INSTALLATION
MOUNTING THE BRACKET
Refer to Figures 4a and 4b.
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. Alonger lag bolt may be
required to properly secure the unit. See Figure 4a.
HANGING THE HEATER
1) Attach the heating unit to the mounting bracket.
2) Lift the heater up and into the mounting bracket.
3) Align the bracket screws with the keyhole slots in the mounting bracket.
4) If the heater is to be tilted it must be positioned in the keyhole slots - see
figure 5.
5) Tighten the bracket screws with a wrench so the unit is securely
suspended at horizontal or vertical level.

ADJUSTING AIR FLOW DIRECTION
1. To turn the unit when it has been installed with a single lag bolt (as shown in
figure 4a), simply turn the entire heater as needed. 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 5).
NOTE: For the heater to be tilted vertically, it must be mounted in bottom
keyhole slots of mounting brackets to maintain adequate clearance and
prevent possible overheating.
1. 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.
To prevent possible electric shock, disconnect power to the
heater at the main service box before attempting to adjust the heat output of
this unit.
MAINTENANCE INSTRUCTIONS
MAINTENANCE AND CLEANING
1. Before cleaning, make sure the power has been turned off at the circuit
breaker panel and that the heating element of the heater is cool.
2. To maintain the external appearance of the radiator, it need only 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 should be
the best opportunity to wipe over with a damp cloth.
