5. The mounting structure and the anchoring hardware must be capable of reliably
supporting the weight of the heater and if used the mounting bracket.
6. All electrical power must be disconnected and the main service box must be locked
before inspecting cleaning or servicing the hater. 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 off the floor.
Improper installation or failure to follow the procedures outlined in this
instruction manual can result in serious electrical shock.
LOCATING HEATER
Install heater out of traffic areas maintaining clearances stated in figure 2. The direction of
air flow should not be restricted is 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 arranged 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 3.

MOUNTING THE BRACKET
Ceiling mounting
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. A longer 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.

Warning: This appliance must be grounded!
Warning: The appliance must connect to a current protection circuit or device at
50Amp or less before being connected to power supply!
1. Remove the screw from the front of the unit to connect the power to the heater.
2. Attach the cable connectors to the unit (See Figure 6) and slide the 10-gauge wire
through the cable connector.
NOTE: All wiring must be carried out by a Certified Electrician and must be in
accordance to national and local electrical codes in the United States. For certain
applications, conduit may be required, See Figure 6. Check local electrical codes. If
you run the wiring in conduit and wish to be able to turn the heater be sure to
purchase enough flexible conduit to allow the heater to be turned.
3. Connect the wire to the power block located in the base of the heater - See Figure 7.
4. Turn on the power at the main service.
CAUTION:
High temperatures – risk of fire. Keep flammable materials, such as furniture, pillows,
bedding, papers, clothes and curtains at least 3 ft. (0.9 m) from the front and top of the
heater and keep them away from the sides and rear.
