l Use a dedicated 10 Amp (or higher) breaker.
l This heater is hot when in use. To avoid burns, DO NOT let bare skin touch hot surfaces. If
provided, use handles when moving this heater. Keep combustible materials, such as
furniture, pillows, bedding, papers, clothes, and curtains at least 3 feet (0.9m) from the front of
the heater and keep them away from the sides and rear.
l Extreme caution is necessary when any heater is used by or near children or invalids and
whenever the heater is left operating and unattended.
l Do not operate any heater after it malfunctions. Disconnect power at service panel and have
heater inspected by a reputable electrician before reusing.
l Do not use outdoors.
l To disconnect heater, turn controls to off, and turn off power to heater circuit at main disconnect
panel (or operate internal disconnect switch if provided).
l Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may
cause an electric shock, fire, or damage the heater.
l To prevent a possible fire, do not block air intakes or exhaust in any manner.
l A heater has hot arcing or sparking parts inside. Do not use in areas where gasoline, paint,
flammable vapors, or liquids are used or stored.
l Use this heater only as described in this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or injury to persons.
l This heater may include an audible or visual alarm to warn that parts of the heater are getting
excessively hot. If the alarm sounds (or illuminates), immediately turn the heater off and inspect
for any objects on or adjacent to the heater that may have blocked the airflow or otherwise
caused high temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE
ALARM SOUNDING (OR ILLUMINATING).
l ALWAYS plug heaters directly into a wall outlet/receptacle. NEVER use with an extension cord
or relocatable power tap (outlet/power strip).
l NEVER use this heater in bathrooms, laundry rooms, or any other location where the heater
could fall into a bathtub, pool, become damp, or come in contact with water.
l AVOID FIRE! Regularly inspect all air vents to make sure they are free from dust, lint, or other
blockage. Unplug the unit and clean with a vacuum ONLY. DO NOT rinse or get wet.
l ALWAYS mount to wall bracket before use. DO NOT set on the floor, or other surface, to use.
l NEVER use a wall mount bracket from another manufacturer.

l This product is not intended to be a primary heat source. It is for supplemental heat only.
l ALWAYS disconnect this unit from the power supply before performing any assembly or
cleaning, or before relocating the electric fireplace.
l ALWAYS store this heater in a dry location. NEVER use the fireplace if it has become wet.
l NEVER plug this heater into an outlet that is old, cracked, or has any loose wires or
connections. Plugging this heater into a faulty outlet could result in electric arcing within the
outlet that could cause the outlet to overheat or catch fire.
l ALWAYS check your heater cord and plug connections with each use.
i) MAKE SURE the plug fits tight in the outlet. Faulty wall outlet connections or loose plugs can
cause the outlet to overheat.
ii) Heaters draw more current than small appliances. Overheating may occur even if it has
not occurred with the use of other appliances.
iii) During use check frequently to see if the plug outlet or face plate is HOT.
iv) If the outlet or face plate is HOT, discontinue use immediately and have a qualified
electrician inspect and/or replace the faulty outlets.
l SAVE THESE INSTRUCTIONS.
