WARNING: Risk to Children and Impaired Persons
- Extreme caution is required during the installation, operation,
cleaning and maintenance of this product by or around children
12 years of age and younger and anyone with reduced physical,
sensory or mental capabilities, and whenever the heater is left
operating and unattended. Children should be supervised to ensure
that they do not play with the appliance, its parts and packaging
material.
INSTALLATION WARNING—To reduce risk of re, electrical shock
and injury to persons, observe the following:
- A heater has hot and arcing or sparking parts inside. Do not use it in
areas where gasoline, paint, or ammable liquids are used or stored.
- Do not use this heater in an RV, boat or during any application
where battery power is converted to AC power.
- Place this product at least 3 feet away on all sides from, electrical
outlets, furniture, pillows, bedding, papers, clothes, curtains and
other objects that may cause or catch on re. Do not place the
heater near a bed because objects such as pillows or blankets can
fall off the bed and be ignited by the heater.
- To prevent a possible re, do not place the heater on soft
surfaces, like a bed, where air intakes or exhaust can be blocked in
any manner.
- No part of this product (the appliance, power cord, plug, packaging,
etc.) should be placed near furnaces, replaces, stoves or other high
temperature heat sources. Do not use in a window, on an uneven or
unstable surface, or near water.
- Do not use this product on an elevated surface such as a shelf or
desktop. Use only while placed on the oor. Operate only in the
upright position.
- The appliance, power supply, power cord and plug cannot come
into contact with water. Do not use this product on wet surfaces.
Do not use this product in a bathtub or shower or position product
where it may fall into a bathtub, laundry, swimming pool or other
water container. Do not use this product outdoors or expose it to
weather or elements.

English
- Do not run cord under carpeting. Do not cover cord with throw
rugs, runners, or similar coverings. Do not route under furniture or
appliances. Arrange cord away from trafc area and where it will not
be tripped over. The cord should not hang over edges of counters
or be placed where it can be crimped or closed in doors. Place
appliance near an easily accessible outlet so the product can be
unplugged quickly during an emergency.
- Do not modify the product with any aftermarket accessory.
SAFE USE WARNING—To reduce risk of re, electrical shock and
injury to persons, observe the following:
- Use this heater only as described in this manual. Any other use not
recommended by the manufacturer may cause re, electric shock, or
injury to persons.
- Extreme caution is required at all times a heater is in operation.
Always unplug heater when not in use. Vornado does not
recommend unattended and unsupervised use of this heater.
- 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.
- Always plug heaters directly into a wall outlet/receptacle. Never use
with an extension cord or relocatable power tap (outlet/power strip).
Do not use this heater on a surge-protected unit or Ground Fault
Circuit Interrupted (GFCI) outlet.
- This product’s power cord is equipped with a three-prong,
grounded plug that must be inserted into a grounded receptacle.
Connect to properly grounded outlets only.
- Before plugging power cord into electrical outlet, be sure that
all electrical information on the rating label, including voltage, is
compatible with your outlet’s power supply.
- WARNING: To reduce likelihood of circuit overload, re and electric
shock, do not operate with a solid state speed device, such as a
dimmer control switch. Use of this appliance on the same electrical
circuit as another high energy use product, such as a vacuum
cleaner, blender, variable speed fan or circular saw is not advised.
Do not use this heater with a timer designed to automatically turn
the unit on or off, as this may accidentally disable the heater’s
thermal cutout safety feature.
- Risk of re. Do not operate any heater with a damaged cord or plug
or after the heater malfunctions, has been dropped or damaged in
any manner. Discard heater, or return to authorized service facility
for examination and/or repair.
- Never use the cord as a handle or otherwise yank, strain or stretch
the power cord.
- While the product is plugged in, 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.
- Check your heater cord and plug connections. A loose tting outlet
can cause the plug to overheat or cause a re. Be sure plug ts tight
in the outlet. Check frequently during use to make sure plug and
outlet are not hot. If so, discontinue using heater and have outlet
replaced by a qualied electrician.
- Never ignore the signs of an electrical problem, such as: warm
outlet coverplates, sparks when plugging in or operating, lights
ickering/dimming during operation. Immediately turn off and
unplug the appliance if any such problems are noticed. Contact a
qualied electrician to investigate possible causes before operating
the appliance again.
- Note: Heaters draw more current than small appliances,
overheating of the outlet may occur even if it has not occurred with
the other appliances.
- This heater is for use with 120 volt electrical outlets. The cord has

6English
a plug as shown at A in Figure 68.1, below. An adapter as shown
at C is available for connecting three-blade grounding-type plugs
to two-slot receptacles. The green grounding lug extending from
the adapter must be connected to a permanent ground such as a
properly grounded outlet box. The adapter should not be used if a
three-slot grounded receptacle is available.
- Before moving, repositioning, servicing, cleaning and when not in
use, use the product controls to turn off the power and then unplug.
To disconnect from outlet, grasp and pull only the plug. Also, power
off and unplug if the product will be left unattended for an extended
period of time or during electrical storms.
- If your heater suddenly stops working:
• This heater is equipped with a thermal cutout safety feature
designed to automatically shut off when overheating is detected.
See the “RESET HEATER” instructions in this guide to determine
how to check and reset the heater.
• If the heater and other electrical products suddenly stop working
at the same time, your home circuit breaker or fuse may have
tripped due to an overload of power. Consider only running your
heater on the “low” setting, only running one heater at once and
unplugging all other electrical products while running the heater,
and/or hiring an electrician to install an additional circuit to your
home’s electrical system.
SERVICING WARNING—To reduce risk of re, electrical shock
and injury to persons, observe the following:
- Clean your product regularly, only as is instructed in this manual.
Prior to cleaning, turn off the power on your product and unplug. Do
not use gasoline, thinners, solvents, ammonias or other chemicals
for cleaning. Refer to the CLEANING instructions provided.

soft, dry cloth.
You should periodically blow
out the heater with pressurized
air to keep heat element and

by accumulation of these particles
inside the unit.
