reduce the risk of re, electric shock, and

injury to persons, including the following:

1. Read all instructions before using this heater.

2. This heater does not include a tip over switch.

It must be monitored at all times

during use to prevent tipping and re,

especially if pets or children are in the house.

3. This heater is hot when in use. To avoid burns, do not
let bare skin touch hot surfaces. Use handles when
moving this heater. Keep combustible materials, such
as furniture, pillows, bedding, papers, clothes, and
curtains at least 3 feet (0.9 m) from the front of the
heater and keep them away from the sides and rear.

4. Extreme caution is necessary when any heater is
used by or near children or invalids and whenever
the heater is left operating and unattended.

5. Always unplug heater when not in use.

6. Do not operate any heater with a damaged cord
or plug or after the heater malfunctions, has been
dropped or damaged in any manner. Return heater
to 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 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 similar coverings.

Arrange cord away from trafc area and

where it will not be tripped over.

10. To disconnect heater, turn controls to
off, then remove plug from outlet.

11. Do not insert or allow foreign objects to enter any
ventilation or exhaust opening as this may cause

an electric shock or re, or damage the heater.

12. To prevent a possible re, do not block air intakes or
exhaust in any manner. Do not use on soft surfaces,
like a bed, where openings may become blocked.

16. The output of this heater may vary and its
temperature may become intense enough to
burn exposed skin. Use of this heater is not
recommended for persons with reduced sensitivity
to heat or an inability to react to avoid burns.

17. Heater service must be performed only
by an authorized service representative.

Service or maintenance performed by unqualied
personnel could result in a risk of re or injury.

18. This double insulated heater is equipped with a
polarized plug (one blade is wider than the other).

This plug will t in a polarized outlet only one way.
If the plug does not t fully in the outlet,
reverse the plug. If it still does not t, contact a
qualied electrician to install a polarized outlet.

Do not change the plug in any way.
Connect to properly grounded outlets only.

19. Do not abuse the Power Cord. Never use the
Power Cord to carry this heater or pull the Plug
from an outlet. Keep the Power Cord away from
heat, oil, or sharp edges. Replace damaged
Power Cords immediately. Damaged Power
Cords increase the risk of electric shock.

20. Disconnect the Power Cord Plug from the power
source and allow the heater to thoroughly cool
before making any adjustments, changing
accessories, or storing this heater. Such preventive
safety measures reduce the risk of burns.

21. When servicing this heater, use only identical
replacement parts. Follow instructions in the
“Maintenance and Servicing” section of this manual.
Use of unauthorized parts or failure to
follow maintenance instructions may create
a risk of electric shock or injury.

physician(s) before use. Electromagnetic elds in

close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.

23. WARNING: Handling the cord on this product will
expose you to lead, a chemical known to the State of
California to cause cancer, and birth defects or other
reproductive harm. Wash hands after handling.
(California Health & Safety Code § 25249.5, et seq.)
