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 ash of light each
time it opens or closes to cycle the element on or off. While this visual ash 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 features an automatic safety switch which turns the unit OFF in case of accidental tip-over. Plus a loud buzzer
sounds a warning if tip-over occurs while the element is cycled ON. The buzzer is designed to be extremely sensitive and
to provide a warning tone whenever the heater is moved while cycled ON. In addition, the buzzer
may sound and the heater will shut off if too much dust or dirt has accumulated on the parabolic
reector. To clean the parabolic reector, see cleaning instructions on page 4.
With the “Thermostatic Control” knob (Fig. B) 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.
Your Presto Parabolic Heater is shipped completely assembled. Before using the heater for the rst time, familiarize
yourself with the parts of the heater (Fig. A) and read the information on the following pages. For proper operating position,
stand the heater upright with the bottom of the base resting at on the oor.
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. Check to 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 reector 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 nd 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 recommended. 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. Warning: Some people
with sensitive skin may develop certain skin conditions such as erythema ab igne when they are exposed to heat sources
such as car heaters, electric blankets, heating pads, hot water bottles, and heaters. Symptoms may include irritation or
discoloration of the skin. Some people may have nerve conditions that reduce their ability to feel direct heat. The heater
is not recommended for use by or in close proximity to persons with these kinds of sensitive skin or nerve conditions.
Never use a heater with a damaged cord.
