bathtub or other water container.
WARNING! To reduce the risk of
fire, electric shock, or personal injury,
read all the instructions before using
this heater. This appliance is
intended for household or personal
use only as described in this manual.
Any other use including but not
limited to commercial, agricultural or
outdoor use, is not recommended by
the manufacturer and may cause
fire, electric shock, injury and/or
damages. The use of attachments
and accessories not recommended
or sold by Dr. Infrared Heater
Products may cause hazards and
void the warranty.

7. Do not run the cord under
carpeting and do not cover the
cord with throw rugs, runners or
the like. Do not route cord under
furniture or appliances. Arrange
the cord away from traffic areas to
avoid a tripping hazard.
8. To disconnect the heater, turn
controls to OFF, then remove plug
from outlet.
9. Do not insert or allow foreign
objects to enter any ventilation or
exhaust opening as this may
cause an electric shock, fire, or
damage to the heater.
10. Connect to properly grounded
outlets only.
11. To prevent a possible fire, do not
block air intakes or exhaust
openings in any manner. Do not
use on soft surfaces, like a bed,
where openings may become
blocked. Use the heater on flat,
dry surfaces only.
12. A heater has hot and arcing or
sparking parts inside. Do not use

inspect for any objects on or
adjacent to the heater which may
cause high temperatures. DO
NOT OPERATE THE HEATER
UNTILIT IS RESET. To reset the
heater, turn it OFF, unplug it from

relocatable power tap
(outlet/power strip).
18. It is normal for the heater’s plug
and cord to feel warm to the
touch. A plug or cord which
becomes hot to the touch or
becomes distorted in shape may
be a result of a worn electrical
outlet. Worn outlets or
receptacles should be replaced
prior to further use of the heater.
Plugging this heater into a worn
outlet may result in overheating
of the power cord or fire.
19. Make sure the plug is fully
inserted into an appropriate
receptacle. Be mindful that
receptacles also deteriorate due
to aging and continuous use.
Check periodically for signs of
overheating or deformations of
the plug. If any overheating or
deformation occurs, immediately
discontinue using the heater and

contact Dr. Infrared Heater
Authorized Service Center.
20. CHECK YOUR HEATER CORD
AND PLUG CONNECTIONS.
Faulty wall outlet connections or
loose plugs can cause the outlets
or plug to overheat. During use,
please check frequently to
determine if your plug, outlet or
faceplate is HOT! If so,
discontinue using the heater
and/or have a qualified electrician
to check and replace the faulty
outlet(s).
CAUTION: This appliance is not intended
for use by persons (including children)
with reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, unless they have been given
supervision or instruction concerning use
of the appliance by a person responsible
for their safety.

Operating Instructions
1. Plug the power supply cord into a
grounded wall outlet (120VAC,
60Hz).
Important:This heater comes with a
grounded (three-prong) plug. The
grounded plug must be used with a
grounded outlet. Do not use an
adapter in a two-slot wall outlet unless
the ground plug of the adapter
properly connects to a building ground.
Using the heater without a properly
grounded outlet or adapter could
result in an electric shock hazard.
The cord has a plug as shown at A in
the figure that follows. 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.

QUESTIONS AND ANSWERS
Why does the blower fan keep running after I have pressed the power off
button?
The blower fan will continue to run until the heat chambers cool down. After a
few minutes the fan will shut off automatically.
What if the heater’s airflow seems to have diminished?
Please ensure the rear intake is not blocked and that the filter is clean. Please
follow the filter maintenance procedure to clean the filter.
Once the heater is turned on, how long will it take to heat my room?
This heater can heat up to 1,000 square feet. Generally speaking, it takes
minutes to heat a room. Remember that with any type of heating process,
there are many variables such as the size of the room, how well the room is
insulated, how many doors and windows there are, the amount of bare
concrete (which acts as a heat sink with any type of heating), the opening and
closing of an exterior door, the outside temperature, etc. Please remember
that this is a zone heater and is meant to be used as a supplemental heating
source only.
Can I use the heater to heat multiple rooms at the same time?
Keep in mind that heating will vary based on how open your floor plan is
and the size of the rooms involved. We have heard from customers that
with the help of ceiling fans, they have been able to heat multiple rooms
simultaneously by placing the unit in a central room. We suggest you give it
a try and see what works best for you.
My home is not well insulated; will this heater help me?
Yes, but it may take a little longer to heat the room. The outside temperature
will also have an impact on heating time. Once the room has reached the
desired temperature, it will cycle on and off accordingly.

Can the heater be used in a bathroom?
It is not recommended due to a bathroom’s high level of moisture.
Can the heater be used in a basement or garage?
Yes, but keep in mind that rooms with little insulation will not retain the heat as
efficiently. Bare concrete floors act as a heat sink with any type of heating and
will absorb some of the heat. However, placing the heater a few feet above the
floor will allow for more efficient heating.
Can I use more than one heater at a time?
Yes, but please make sure the heaters are not on the same circuit. Each
heater and appliance should be on its own circuit.
Can I use the heater and another appliance at the same time?
Yes, as long as they are not on the same circuit. This heater is considered to
be an appliance. You should not run more than one large appliance on a single
circuit breaker. Your appliances, such as a freezer, refrigerator, microwave
oven, washing machine, dryer and others, should not share a circuit breaker.
Can I use the heater on a job or construction site?
This heater is not designed to be used in a high dust construction environment.
Using the heater for this purpose will void your warranty.
Can I move the heater around while it is operating?
It is not recommended to move any portable heater while it is operating. We
recommend moving the heater only once the fan has completely turned off.
What is the life expectancy for the heater?
This heater uses one infrared tube (which is rated for 20,000 hours and up),
and one PTC element (which is rated for 80,000 hours and up).

What is zone heating?
Zone heating focuses heat where people spend the most time. After all, there
is no point in heating multiple rooms to +68 degrees when not in use.
Can I use an extension cord, surge protector, or power strip with my
heater?
No. The DR. INFRARED HEATER is designed to plug directly into a grounded
120V 15 Amp or higher circuit receptacle. Never use with an extension cord or
relocatable power tap (outlet/power strip).
How many kilowatts per hour does the heater use?
The DR. INFRARED HEATER MODEL DR-998 uses approximately
1.26 kilowatts per hour.
What is the BTU Rating for the heater?
The DR. INFRARED HEATER MODEL DR-998 is approximately 5200 BTUs.
The power cord feels warm to the touch; should I be concerned?
It is normal for the heater’s plug and cord to feel warm to the touch. A plug or
cord which becomes hot to the touch or becomes distorted in shape may be a
result of a worn electrical outlet. Worn outlets or receptacles should be
replaced prior to further use of the heater. Plugging this heater into a worn
outlet may result in overheating of the power cord or even a fire.
I don’t have a grounded outlet; can I use a cord adapter or remove the
grounding plug?
NO. If you don’t have a grounded outlet, contact a licensed electrician in your
area for advice. Removing or altering any part of the heater is unsafe and will
also void your warranty.

How long is the warranty?
This heater comes with a THREE-YEAR LIMITED WARRANTY. If your unit
does not appear to be working properly, please contact our service center by
calling 1-800-317-1688. Prior to your call, we encourage you to visit our
service related website www.DrHeaterUSA.com for troubleshooting tips and
