IMPORTANT INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS BEFORE USING THIS HEATER
NOTE: There may be a trace of smoke or odor when unit is first operated. Do not be alarmed. This
indicates that a drop of oil fell on the heating coil during the manufacturing process. It will quickly
evaporate and should not recur.
Make sure that the room in which the appliance is located is well ventilated during this operation. It
is normal for the appliance to emit small cracking sounds when you turn it on for the first time.
Again, do not be alarmed.
WHEN USING ELECTRICAL APPLIANCES, BASIC PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO
REDUCE THE RISK OF FIRE, ELECTRICAL SHOCK AND INJURY TO PERSONS OR PROPERTY,
INCLUDING THE FOLLOWING:
1. Read all instructions before using this heater.
2. This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Keep combustible
materials, such as furniture, pillows, bedding, papers, clothes and curtains at least 3 ft. (0.9 meters) from the
front and top of the heater and away from the sides and rear. Ensure a minimum clearance of 5.5 inches
(14 cm) from both sides and rear of heater to adjacent walls. Keep the rear grille away from walls or drapes
so as not to block the air intake.
3. Extreme caution and reasonable supervision is necessary when any heater is used by or near children or
the physically challenged and whenever the unit is operating and unattended.
4. Always unplug the heater when it is not in use. To disconnect, grip plug and pull from wall outlet. Never
yank on the cord.
5. To disconnect the heater, turn controls to OFF, and then remove the plug from outlet.
6. Do not operate any heater with a damaged cord or plug, or after the heater malfunctions or has been
dropped or damaged in any manner. Return the heater to an authorized service facility for examination,
electrical or mechanical adjustment, or repair.
7. Do not use outdoors.
8. This heater is not intended for use in bathrooms, laundry areas and similar indoor locations. Never locate
the heater where it may fall into a bathtub or other water container.
9. Do not run cord under carpeting. Do not cover cord with throw rugs, runners or the like. Do not use on soft
surfaces, or under furniture or appliances. Arrange cord away from traffic area to avoid a tripping hazard.
Route the cord so that it will not be walked on, nor pinched by furniture.
10. Connect to properly grounded outlets only. Check heater voltage and amperage on the back of the heater to
make sure it agrees with the electric service supplied.
11. Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an
electric shock, fire or damage to the heater.
12. To prevent a possible fire, do not block air intakes or exhaust in any manner. Do not use on soft surfaces,
like a bed, where openings may become blocked.
13. Use this heater only as described in this manual. Any other use not recommended by the manufacturer may
cause fire, electric shock, injury to persons or other damage to property.
14. This heater draws 23.4 amps during operation. Be sure to use a dedicated 240VAC, 30A circuit for the
heater.
4
15. It is normal for the heater’s plug and cord to feel warm to the touch. A plug or cord which becomes hot to the
touch or becomes distorted in shape may be a result of a worn electrical outlet. Worn outlets or receptacles
should be replaced prior to further use of the heater. Plugging the heater into a worn outlet or receptacle
may result in overheating of the power cord or even a fire.
16. Ensure the heater is on a stable, secure floor surface to eliminate the potential of tipping it over.
17. Be sure that the plug is fully inserted into appropriate receptacle. Please remember that receptacles also
deteriorate due to aging and continuous use: check periodically for signs of overheating or deformations
evidenced by the plug. Should this occur, do not use the receptacle if deteriorated. Call your electrician.
18. Check that neither the appliance nor the power cable has been damaged in any way during transportation.
19. Make sure that no pieces of polystyrene or other packaging material have been left between one element of
the appliance and another. It may be necessary to pass over the appliance with a vacuum cleaner.
20. When switching on the appliance for the first time, you may notice a slight odor which is normal with new
electrical appliances. Allow the odor to dissipate by running the appliance at full power for about ten
minutes. Make sure that the room in which the appliance is located is well ventilated during this operation.
This heater draws 23.4 Amps during operation. To prevent overloading a circuit, do not plug the heater into
a circuit that already has other appliances working.
21. Do not run in locations when the heater will be left unattended for long periods of time (for example, in an
unoccupied summer cottage).
22. Do not use attachments or filters. They are not recommended.
23. Always plug the heater directly into a wall outlet/receptacle. Never use with an extension cord
or relocatable power tap (outlet/power strip). A heater has hot and arcing or sparking parts
inside. Do not use it in areas where gasoline, paint, or flammable liquids are used or stored.

IMPORTANT!!
THIS HEATER IS FOR USE ON THE FLOOR ONLY.
Prior to operating the heater, ensure the electrical receptacle is of the configuration and capacity appropriate
for the heater. See receptacle configuration in OPERATING INSTRUCTIONS. This heater is for use on
240 volts. The cord has a plug as shown in #6 above. No adapter is available for this blade configuration, and
none should be used. The type of receptacle is a 240-volt grounding receptacle (NEMA 6-30R). When properly
installed, it provides a ground connection through the cord to the heater to protect the operator from electric
shock.

YOUR HEATER IS EQUIPPED WITH A THERMOSTAT:
1. Turn the unit ON by turning the thermostat dial away from the OFF position.
2. For faster heat-up or to increase the heat output, turn the Thermostat Control knob all the way to the right [HIGH].
The thermostat function controls the temperature output. To decrease the heat output, turn the knob counter-
clockwise.
3. Once the room reaches the desired temperature, slowly turn the Thermostat Control knob counter clockwise until
you hear a “click.” This sets the heater to cycle ON/OFF to maintain the desired heating temperature for energy
efficiency.
4. To completely shut off the unit, turn the thermostat dial to the OFF position and unplug the heater.
