Electrical Safety
3. Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
4. Do not expose appliances to rain or wet conditions. Water entering a appliance
will increase the risk of electric shock.
5. Grounded products must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter plugs.
Check with a qualified electrician if you are in doubt as to whether the outlet
is properly grounded. If the product should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user.
6. Double insulated appliances are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a polarized outlet. Do not change
the plug in any way. Double insulation eliminates the need for the three wire
grounded power cord and grounded power supply system.
7. Do not abuse the Power Cord. Never use the Power Cord to pull the Plug from
an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving
parts. Replace damaged Power Cords immediately. Damaged Power Cords
increase the risk of electric shock.
Personal Safety
8. Stay alert. Watch what you are doing, and use common sense when operating
this product.
9. Avoid accidental starting. Be sure the Fan Switch is off before plugging in.
Tool Use and Care
10. Do not use this appliance if any switch or thermostat does not work properly.
11. Disconnect the Power Cord Plug from the power source before making any
adjustments to the appliance. Such preventive safety measures reduce the risk of
starting the appliance accidentally.
Service
12. Appliance service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could result in a risk of
injury.

13. When servicing an appliance, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions may
create a risk of electric shock or injury.
SPECIFIC SAFETY RULES FOR THIS PRODUCT
1. Maintain labels and nameplates on the Fireplace Heater. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
2. Avoid fires and explosions. Never place the Fireplace Heater near room curtains
or other flammable materials. The floor on which the Fireplace Heater sits must be
nonflammable and free of debris. Never use near flammable vapors or liquids.
3. Maintain a safe working environment. Keep the work area well lit. Make sure there
is adequate surrounding space. Always keep the work area free of obstructions,
grease, oil, trash, and other debris. Do not use this product in areas near flammable
chemicals, dusts, and vapors. Do not use this product in a damp or wet location.
4. Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Fireplace Heater.
5. Do not force the Fireplace Heater. This product will do the work better and safer at
the capacity for which it was designed.
6. Always unplug the Fireplace Heater from its electrical outlet before performing
and inspection, maintenance, or cleaning procedures.
7. Never leave the Fireplace Heater unattended while running. Turn power off if you
have to leave the room.
8. Use proper extension cord. If an extension cord is used, use the proper type as
listed in the table on page 7. Keep extension cord off the ground and away from water.
9. Connect to a GFCI outlet. Always connect the Line Cord to a Ground Fault Circuit
Interrupter (GFCI) protected electrical outlet.
GROUNDING
Note: This product comes with a two-prong, polarized plug.
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. Do not modify the power cord plug provided
with the tool or product. Never remove the grounding prong from the plug.
Do not use the tool if the power cord or plug is damaged. If damaged, have
it repaired by a service facility before use. If the plug will not fit the outlet,
have a proper outlet installed by a qualified electrician.

Grounded Tools: Appliances with Three Prong Plugs
1. Appliances marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If the
appliance should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See Figure A.)
2. The grounding prong in the plug is connected through the green wire inside the cord
to the grounding system in the appliance. The green wire in the cord must be the only
wire connected to the appliance’s grounding system and must never be attached to an
electrically “live” terminal. (See Figure A.)
3. Your appliance must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet should
look like those in the following illustration. (See Figure A.)
Double Insulated Appliances: Appliances with Two Prong Plugs
4. Appliances marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard
Association, and the National Electrical Code. (See Figure B above.)
5. Double insulated appliances may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B above.)
EXTENSION CORDS
1. Grounded tools require a three wire extension cord. Double Insulated tools can use
either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a serious
drop in voltage, resulting in loss of power and possible tool damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See
Table A.)
4. When using more than one extension cord to make up the total length, make sure
each cord contains at least the minimum wire size required. (See Table A.)
Figure A Figure B

Page 6SKU 91797 For technical questions, please call 1-800-444-3353
5. If you are using one extension cord for more than one appliance, add the nameplate
amperes and use the sum to determine the required minimum cord size. (See Table
A.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician
before using it.
8. Protect your extension cords from sharp objects, excessive heat, and damp or wet
areas.
