IMPORTANT SAFETY INSTRUCTIONS
WARNING: POTENTIAL ELECTRICAL HAZARD IF NOT ADHERED TO. When using electrical appliances,
basic precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons,
including the following:
• This heater must be plugged into a 120 V, 15 amp (or more) circuit of its own. Do not plug anything else
into the same circuit. If unsure if your home meets this specification, consult a certified electrician prior
to use. Risk of fire, overheating, malfunction, property damage, injury, or even death may result if
not adhered to!
• Connect to a properly grounded, 3-prong outlet only. Do not connect the heater to extension cords,
surge protectors, timers, direct breakers, or an outlet with other appliances connected to the same
outlet. Risk of fire, overheating, malfunction, property damage, injury, or even death may result if
not adhered to!
• This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Use handles
(certain models) or wheels to move this heater.
• Keep combustible materials, such as furniture, pillows, bedding, papers, clothes, and curtains at least 3
ft. (0.9 m) from the front of the heater and keep them away from the sides and rear of the heater.
• Extreme caution is necessary when any heater is used by or near children, invalids, pets, or when the
heater is left operating unattended.
• Always unplug the heater when not in use.
• Do not operate any heater with a damaged cord or plug or after the heater malfunctions, has been
dropped, or damaged in any manner. Contact the manufacturer for resolution options.
• Do not use outdoors. Exposure to outdoor elements such as rain, snow, sun, wind, or extreme
temperatures may cause the heater to become a safety hazard.
• This heater is not intended for use in bathrooms, laundry areas, and similar indoor locations, nor any
locations that use GFCI outlets.
• Never place the heater where it may fall into a bathtub or other water receptacles.
• Do not run the cord under carpet. Do not cover the cord with throw rugs, runners, or similar coverings.

FREQUENTLY ASKED QUESTIONS
Please review these frequently asked questions on the next few pages prior to using your heater.
Q. My heater emits a strange odor when I first open the box and when I turn the heater on for the first
time. Why is this happening?
A. This is normal. This heater is treated with a special heat safe/resistant coating. This odor will sometimes
be present when the box is opened. When the coating is exposed to heat, it produces this particular odor
during the first few hours of operation. This will dissipate after the break-in period. If you are sensitive to
odors, you may want to pre-burn the unit in a garage with the door open until the initial odor dissipates.
Q. If my heater runs on its max wattage setting, how many BTUs is that?
A. This heater is intended to be used as supplemental heat in areas most needed. It may take several
minutes to several hours to heat your area, depending on various factors. The below chart provides BTU
translations for different wattages.
WATTAGE BTUS
1,500 5,118
1,000 3,412
750 2,559
500 1,706
Q. Can the heating elements be replaced?
A. Replacement heating elements can be obtained from the manufacturer. All parts may be purchased
through the manufacturer if your product is out of warranty. If you feel that the elements are definitely
faulty right out of the box, contact Customer Support. A representative can then direct you to the next step.
Q. Once I plug the unit in and turn it on, how long will it take to heat my room?
A. The heating process in the heater begins immediately upon powering on and setting the desired
temperature above the ambient temperature. A noticeable change in the ambient temperature of the
room will vary due to variables such as the location of the heater (in the home), floor plan and size of the
room, how well the room is insulated, how many doors/windows, how much bare concrete (acts as a heat
sink with any type of heating), the opening and closing of an exterior door, long hallways, high ceilings, etc.
Customers with smaller rooms experience quick heat changes. Rooms with larger and open floor plans
can expect up to 24 hours to completely heat up.
Q. I do not have a grounded outlet. Can I use adapters, a 2-prong power strip, or remove the ground
prong from the cord?
A. NO! If you do not have a grounded outlet, contact a certified electrician for advice. Removing or altering
any part of the heater’s original design or intent (including the power cord) will void the warranty and
make you liable for any unexpected or hazardous results.
Q. My Heater has an ECO setting? How does this setting work?
A. The ECO mode on your heater is a program that attempts to keep the temperature strictly at a “warm”
68° F (20°C). This also helps with efficiency, as it is programmed to 1) Increase the power to the unit’s
maximum wattage if the temperature drops below 64.4°F (18°C) 2) Gradually reduce the wattage used
as it approaches 66.2° (19°C) F and 3) Stop heating when 68° F (20°C) is achieved. This is considered an
Economical function, since in the ECO setting, the heater is almost never running at the maximum watts.

FREQUENTLY ASKED QUESTIONS
Q. The temperature on my heater does not match the temperature display on my wall, or external
thermostat. Why?
A. This is completely normal. The temperature display on your heater may vary from the temperature
display on another thermostat (like the one mounted to your wall or a purchased external thermostat).
This is because the temperature sensor on the heater reads the temperature directly around the heater.
With the heater near the cold floor (and heat rising), any readings on elevated or external thermostats
will differ in readings on the heater. The best way to operate your heater is to set the unit on High and dial
up to a temperature that feels comfortable to you. Then, leave it at that temperature, regardless of the
mismatch. The heater will cycle off when the set temperature is met or exceeded slightly.
Q. Can I use more than one heater at a time? Can I use the heater and another appliance at the same
time?
A. Yes, but make sure they are not plugged into the same circuit. Each heater requires its own minimum 15-
amp circuit with no other items plugged into that circuit or outlet. This is because heaters are considered
appliances and draw out high amperage. If you are unsure your circuit meets these requirements, verify
with a certified electrician.
WARNING: Risk of fire, damage to property, or injury may result if requirements are not met.
Q. Why does my heater’s fan continue to run after the set temperature is reached or the power is turned off?
A. This is normal. The heater’s fan will continue to run even after the heater automatically cycles down.
The fan continues to run so that every last bit of heat is blown out of the heat chamber while allowing the
unit to continue filtering your air. Once the internal box/components cool completely, the fan should then
shut off on its own. In this case, allow a few minutes after the heat cycles off (with power on). The fan will
shut off faster when the power is turned off.
Q. My heater’s display shows my ambient temperature to be in the 20s when I know it is warmer than
that. Why?
A. The heater’s display is defaulted to read the temperature as Fahrenheit. If your heater is definitely
heating but shows it is in the 20s you probably have the setting to read your temperature in Celsius rather
than Fahrenheit.
Q. My heater’s power cord gets warm. My cord is showing signs of heat or melting at the outlet. Is this
normal?
A. A warm power cord is normal. These power cords are rated safe for up to 105°C/ 221°F by the UL, CSA,
or ETL. The exception is, if you detect heat, smoke, or signs of melting at the contact point of the wall
outlet, it may be due to loose or worn wall contacts (or arcing). Please stop using the heater immediately,
contact warranty support for a replacement power cord, and have a certified electrician replace the wall
outlet as soon as possible.

PREPARATION
Place the heater on a firm, level surface and plug into a grounded 120 V, 60 Hz power outlet and turn on
the power switch on the rear of the unit. Only operate heater in upright position.
Insert two AAA batteries into the remote control before using (batteries not included). *(Not all products
will include a remote control.)
Please note that infrared heaters do not heat like a traditional space heater. You should not expect infrared
heaters to blow hot air like a traditional space heater. Infrared heaters heat objects not air. Infrared heaters
are intended to supplement an already heated, insulated room. Square footage specifications assume a
single enclosed room not an entire home. Infrared heaters do not heat through walls, floors, and are
not intended to replace a main heat source. Infrared heat can take at least 24 hours to warm a room but
operate much more efficiently to maintain the desired temperature. Infrared heaters will not work well in
uninsulated unheated spaces like screened in porches, RV’s, garages, unheated basements, etc.
