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

3. Extreme caution is necessary when any heater is used by or near children
or persons with physical challenges and whenever the heater is left
operating and unattended.
4. Do not operate the heater with a damaged cord or plug, or after the heater
malfunctions, has been dropped, or damaged in any manner. Return the
heater to an authorized service facility for examination, electrical or
mechanical adjustment, or repair.
5. Do not use outdoors.
6. This heater is not intended for use in bathrooms, laundry areas, or similar
locations. Never locate the heater where it may fall into a bathtub or other
water container.
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 heater in
areas where gasoline, paint or flammable liquids are used or stored.
13. Use this heater only as described in this manual. Any other use not

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.

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 a large 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.
