AND FAQ’s BEFORE USING THE HEATER
WARNING!
! POTENTIAL FOR ELECTRICAL HAZARD IF NOT ADHERED TO!
When using electrical appliances, basic precautions should always be followed to reduce
the risk of fire, electric shock, and injury to persons, including the following:
1. This heater must be plugged into a 120V, 15 amp (or more) circuit of its own. Nothing
else can be plugged into the same circuit. If unsure if your home meets this
specification, consult a certified electrician prior to use. Risk of fire, overheat,
malfunction, property damage, injury, or even death may result if not adhered
to!
2. Connect to a properly grounded, 3-prong outlet only. Do not connect the heater to
extension cords, surge protectors, timers, direct breakers, or an outlet with other
appliances connected to the same outlet. Risk of fire, overheat, malfunction,
property damage, injury, or even death may result if not adhered to!
3. This heater is hot when in use. To avoid burns, do not let bare skin touch hot
surfaces. Use handles (certain models) or wheels to move this heater.
4. Keep combustible materials, such as furniture, pillows, bedding, papers, clothes, and
curtains from the front of the heater and keep them away from the sides and rear of
the heater.
5. Extreme caution is necessary when any heater is used by or near children, invalids,
pets, or when the heater is left operating unattended.
6. Always unplug the heater when not in use.
7. Do not operate any heater with a damaged cord or plug or after the heater
malfunctions, has been dropped, or damaged in any manner. Contact the
manufacturer for resolution options.

4
8. Do not use outdoors. Exposure to outdoor elements such as rain, snow, sun, wind or
extreme temperatures may cause the heater to become a safety hazard.
9. This heater is not intended for use in bathrooms, laundry areas and similar indoor
locations, nor any locations that use GFCI outlets.
10.Never place heater where it may fall into a bathtub or other water receptacles.
11.Do not run cord under carpet. Do not cover cord with throw rugs, runners, or similar
coverings. Arrange cord away from traffic area and where it will not be tripped over.
12.The heater must be plugged into a wall outlet that is a DEDICATED CIRCUIT, with a
minimum 15 amp rating on that individual circuit.
13.To disconnect the heater: FIRST, turn the power button to the “off” position, then
remove plug from the wall outlet.
14.Do not allow foreign objects to enter or block any ventilation or exhaust opening as
this may cause an electric shock or fire, or damage the heater.
15.Allow at least 3 feet of unobstructed space to the front and rear of the heater to allow
for maximum heat, air, and ventilation flow.
16.A heater has hot and arcing or sparking parts inside. Do not use it in areas where
gasoline, paint, or flammable liquids are used or stored, nor use flammable solvents

FREQUENTLY ASKED QUESTIONS (FAQ’S)
My heater emits a “strange” odor when I first open the box/when I turn the heater on for the first time.
Why?
These are both normal. This heater is treated with a special heat safe/resistant coating. This
odor will sometimes be present when the box is opened, and may be compared to a heaters
version of “new car smell.” Also, similar to all hearth appliances (woodstoves, etc.), the coating,
exposed to heat, will produce this particular odor during the first few hours of operation. This will
dissipate after the break-in period. If you are sensitive to odors, you may want to pre-burn the
unit in a garage with the door open until the initial odor dissipates.
If my heater runs on approximately 1500 watts, how many BTU’s is that? Is that a lot of heat?
At 1500 Watts, your heater will use approximately 5100 BTUs. 5100 BTUs, compared to your
home furnace, is a very small amount of heat. It may take several minutes, to several hours to heat
your area, depending on various factors (see Heater Placement).
Can my heater really operate on less money per day? What are my operating costs?
Yes. If the heater is used as it is intended (as supplement/assist heat), it should cycle on and off,
allowing for it to heat a total of approximately 8 out of the 24 hours of the day. Using the national
average of approximately 10¢ per kWh (look at your bill for exact cost per kWh--will vary per state),
your average heating cost (add a few cents just for having it plugged in) should be less per day
compared to your main furnace. The costs will increase if it is used as the single source of heat, or
if heat somehow escapes the room being heated, since the “on” cycle will run longer.
The Formula: To determine the cost of this or ANY 1500 watt appliance, multiply 1.5 X your cost
per Kilowatt Hour to determine approximately how much it costs you to run the heater. You can find
the cost per KWH prices for your state at: http://www.eia.doe.gov/fuelelectric.html
What is the life expectancy for the Heating Elements? Can the heating elements be replaced?
The life expectancy of the heating elements is typically 25,000 hours. Heating elements may be
replaced by obtaining parts from the Manufacturer, although it is not recommended (unless you are
a certified heater technician or authorized directly by SND). All parts may be purchased through
SND PRODUCTS if your product is out of warranty. Note: If you feel that the elements are
definitely faulty right out of the box, contact a Discovery Tech Support first (for troubleshooting).
They can then direct you on the next step.
Once I plug the unit in and turn it on, how long will it take to heat my room?
The heating process in the heater begins immediately upon setting the desired temperature above
the ambient temperature and powered on. A change in the the actual room temperature will vary.
Please remember that with any type of heating process, there are many variables: Location of
heater (in the home), floor plan and size of the room, how well the room is insulated, how many
doors/windows, how much bare concrete (acts as a heat sink with any type of heating), the
opening and closing of an exterior door, long hallways, high ceilings, etc. Customers with smaller
rooms experience quick heat changes. Others with larger and open floor plans can expect up to 24
hours to heat up.

6
I don’t have a grounded outlet; can I use adapters, a 2-prong power strip, or remove the ground
prong from the cord?
Definitely NOT! If you don’t have a grounded outlet, contact a certified electrician for advice.
Removing or altering any part of the heater’s original design or intent (including the power cord) will
not only void the warranty, but will make you liable for any unexpected or hazardous results.
Why doesn’t the temperature on my heater match the temperature display on my wall, or external
thermostat?
This is completely normal. The temperature display on your heater may vary from the
temperature display on another thermostat (like the one mounted to your wall or a purchased
external thermostat). The temperature sensor on your heater reads the temperature in, and
around, the heater. The unit is near the cold floor (and heat rises), which in turn, will display a
cooler temperature than elevated or external thermostats. The best way to operate your heater is
just to set the unit on “High” and dial up to a temperature that feels comfortable to you. Then, leave
it at that temperature, regardless of the mismatch. The heater will cycle off when the set
temperature is met or exceeded slightly.
My home is not insulated very well, will this heater help me? Can I use the heater if I have vaulted or
cathedral ceilings? I live in a structure that is less than 1500 square feet. Will this heater help me? Can I
use the heater to heat multiple rooms at the same time? Will I be able to use the heater in a basement or
garage?
The answer to these is the same. Yes. You will be able to use it, but keep in mind that
rooms/structures with open floor plans, minimal insulation, adjacent rooms, or high ceilings will not
retain the heat as efficiently, and may not feel pronounced heat changes. Also, the heater will stay
on longer (delays the “off” cycle), and may increase your electric costs. Note that if you do use it in
a garage or basement, the moisture levels must be very low and they must have dedicated circuits
(15 amps minimum) with no GFCI outlets. If unsure what a GFCI outlet is, contact a certified
electrician.
Can I use more than one heater at a time? Can I use the heater and another appliance at the same time?
Yes. But make sure they are not plugged into the same circuit. Each heater (heaters are
considered appliances) requires its own minimum15 amp circuit (with no other items plugged
into that circuit). If unsure your circuit meets these requirements, verify with a certified electrician.
Risk of fire, damage to property, or injury may result if requirements are not met.
Why does my heater’s fan continue to run after the set temperature is reached or the power is turned off?
This is normal. The heater’s fan will continue to run, even after the heater automatically cycles
down. The fan continues to run so that every last bit of heat is blown out of the heat chamber, while
allowing the unit to continue filtering your air. Once the internal box/components cool completely,
the fan should then shut off on its own. In this case, allow a few minutes after the heat cycles off
(with power on). The fan will shut off faster when the power is turned off.
Why doesn’t the fan speed increase when I change the setting from LO to HI?
This is normal. The heater’s fan’s speed is not affected by the HI/LO settings. The fan is designed
to vent the heat at one soft, comfortable, and energy efficient speed. What is affected by the HI
setting is the heat output. In essence, in the HI mode, the heater produces “more” heat, rather than
“faster” heat.

I want to make sure my warranty is registered. What do I send to make sure it is registered?
Where do I send it?
The heater comes with an automatic 1 year limited manufacturer’s warranty at the time of
purchase. Your receipt is considered your proof of purchase and registration. Keep it in a safe
place. As long as it is legible, a copy may be used for any future warranty claims (if requested). If
you have access to e-mail, and would like peace of mind, e-mail us to:
[email protected]. In the body of the e-mail, include your full name, address,
phone number, model, serial number, and scanned copy of your legible receipt.
My heater does not perform as well as another brand heater that I purchased. Why Not?
There are many brands of heaters on the market. Each brand is designed with different heat
specifications, fan speeds, colors, material types, displays, and electrical components. They are
manufactured this way for you, as the consumer to have choices, selection, and preferences. As
long as the unit functions as specifications indicate, comparison to other brands will ultimately
depend on individual consumer perception.
I purchased my heater so that it could cut my heating costs, but my electric bill has gone up. Why?
The compact Discovery heater can definitely save you on heating costs, when compared to the
existing central heating system in place in your home, and when used as directed. Your heater is
designed to give your main heat source a supplement “boost,” or allow for you to have extra heat
(in the form of soft infrared waves) in locations where you would otherwise be short. It is meant to
cycle on and off, and not specifically designed to be used as a single heat source, especially in
larger homes. If you intend on using it as a single heat source (which you may), expect the heater
to 1) take as much as 24 hours to heat the area, 2) stay on for longer periods of time (without
cycling off) due to heat loss, and 3) increased use time, and electric costs.
My heater’s display shows my ambient temperature to be in the 20’s, when I know it is warmer than that.
Why?
The heater’s display is defaulted to read the temperature as Fahrenheit. If your heater is definitely
heating, but shows it is in the 20’s, you probably have the setting to read your temperature in
Celsius, rather than Fahrenheit. See Users Guide to change.
My heater has a temperature setting indicating ECO. It is supposed to be efficient, but it seems to not heat
as much. Why?
The ECO mode on your heater is a program that attempts to keep the temperature strictly at a
“warm” 68° F. This also helps with efficiency, as it is programmed to 1) Increase the wattage used
to 1500W if the temperature drops below 64.4°F 2) Gradually reduce the wattage used as it
approaches 66.2° F and 3) Stop heating when 68° F is achieved. This is considered an Economical
function, since in the ECO setting, the heater is almost never running on the full 1500 Watts. If this
“warm” heat is not plentiful or is on constantly, and you fear it will increase your electric bills, we
recommend you set it to the high or low setting and have it cycle off when your set temperature is
achieved. You may also set the timer to allow your heater to shut off at the given hour increments
you desire.
