How the parabolic heater works...
An automatic control switch, or thermostat, is built into the heater to control the heat output. The control knob (Fig. A), located on the
top of the heater, is used to adjust the thermostat. This thermostat works like the control for a burner on an electric stove by cycling the
heating element on and off to regulate the amount of heat produced. At the highest setting, the element is on 100% of the time. At lower
settings, the element will cycle on and off automatically producing a lesser amount of heat. The lower the heat setting, the longer the
element will remain off during the cycle. This is normal.
Additionally, like the power control switch for any electric device,
this thermostat may produce a small spark or flash of light each
time it opens or closes to cycle the element on or off.
While this visual flash is normal for any electric switch, it may be more noticeable
in the heater, particularly if the room is darkened. Likewise, you may hear a slight humming sound at lower settings as the thermostat
turns the element back on and the unit heats up. This is also normal.
The heater has three safety features:
an automatic safety switch, a manual reset button, and a warning buzzer. The automatic safety
switch turns the unit OFF and the warning buzzer sounds (if the element is energized) whenever the heater is moved or is placed on a
non-level surface. Although chiefly intended as a warning of tip-over, the switch shuts the heater off and the buzzer sounds as an addi-
tional safeguard, for example, when a child or animal moves the heater.
The heater is controlled by a thermostat that shuts the heater off if it overheats, e.g., it is placed too
close to furniture or to a wall or if too much dust or dirt has accumulated on the parabolic reflector. To
ensure that you are aware that an overheat situation has occurred, the heater will turn off and buzz until
you manually reset it.
To reset, press the red recessed POWER RESET button (Fig. B) located on the top of the heater between
the dish and the control knob.
If you hear continuous buzzing,
confirm that the heater is on a level surface. If it is, the heater has
overheated due to incorrect positioning or dirt or dust accumulation on the reflector.
1. Turn the heater control knob dial to OFF.
2. Wait 5 minutes to allow heater to cool.
3. Press down on the red recessed POWER RESET button (Fig. B) with a Phillips screwdriver or similar tool. Press until you hear
a click. If you do not hear the click, continue to press down. The click is an audible signal that the button has been reset.
Then verify heater is correctly positioned (see positioning instructions below) and clean the reflector if it is dirty or dusty, as instructed
on page 4.
With the thermostatic control knob set to the HI position, the electricity is supplied to the heating elements 100% of the time and the
heater is ON constantly. In the LOW position, electricity is supplied to the heating elements only part of the time. This varies with the
room temperature. The colder the temperature is in the room, the more often the heater will cycle on. The heater will automatically
cycle on and off at the LOW setting and maintain a constant temperature. The desired comfort level can be maintained by adjusting the
thermostatic control knob and thereby regulating the total heat output of the unit.
Positioning the heater...
When positioned correctly, the parabolic heater will keep you toasty warm. Follow these suggestions for maximum warmth:
1. Point the front grille towards the area in which heat is desired.
2. Make sure there are no objects between you and the heater. Such objects will absorb the heat and prevent it from reaching you.
3. Place the heater at least 3 feet but no more than 10 feet away. The parabolic design of the reflector focuses heat at persons 3 to 10
feet away. Thus, for your entire body to enjoy the heat produced by the heater, it must be placed at least 3 feet from you. Placing it
closer will turn the heater into a foot warmer, rather than a body warmer. Experiment with various positions until you find the one
that is right for you.
4. Remember, this unit is primarily a people heater rather than a room heater and using it to heat a large room or open area is not rec-
ommended. The infrared heat produced by this heater will travel through glass, just like the sun’s rays. If the heater is aimed at a
window, objects outside will be heated.
When using any heater, the following safety precautions should always be observed:
• Close attention is necessary when the heater is used where children are present.
• The heater should always be in a stable, upright position with at least 3 feet of space between the front of the unit and any other surface.
• The heater should never be placed in a closed area such as beneath furniture, in cabinets, or beneath or behind curtains or drapes, nor
should it be hung from a wall or ceiling.
• Heat produced by any heater tends to pull moisture from the air. It is recommended that you avoid sitting with your face directly in
front of the heating element. The intense heat may dry your eyes and cause irritation.
