12. This 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.
13. Use this heater only as described in this folder. Any other use not recommended by the manufacturer may cause fire, electric shock,
or injury to persons.
14. Always plug heaters directly into a wall outlet/receptacle. Never use with an extension cord or relocatable power tap (outlet/power
strip).
15. This heater includes an audible alarm to warn that parts of the heater are getting excessively hot. If the alarm sounds, immediately
turn the heater off and inspect for any objects on or adjacent to the heater that may cause high temperatures. DO NOT OPERATE
THE HEATER WITH THE ALARM SOUNDING.
16. Do not operate heater with base removed.
17. Do not attempt to repair, adjust, or replace parts in the heater. The Presto Factory Service Department should check and repair
broken heaters.
SAVE THESE INSTRUCTIONS
Important Cord and Plug Information
This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit
into a polarized outlet only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician. Do not attempt to modify the plug in any way.
Connect the power cord to a 120VAC electrical outlet only.
GETTING ACQUAINTED WITH YOUR PRESTO
PARABOLIC HEATER
How the parabolic heater keeps you warm
The Presto
HeatDish
Plus parabolic electric heater is designed to heat people and objects directly, without first heating the air space
around them. The heater allows you to set the room temperature at a low level and still stay cozy warm.
Heat is produced by a coiled wire element wrapped around a ceramic cone. The heater’s parabolic reflector reflects this heat in a con-
centrated beam that shines directly on you. The heat is controlled through an infinite switch which cycles the element on and off, in a
fashion similar to your stove. The higher the setting, the longer the interval during which the element is energized.
The ceramic cone retains the heat, so that there is an even feeling of heat at each setting. At lower settings the heat is less intense, while
at higher ones, it is more intense.
How the parabolic heater can help save energy
The parabolic reflector focuses heat output, like a satellite dish concentrates TV signals, so it requires less energy than convection electric
heaters to deliver all the warmth you’ll want. It provides super concentrated heat to keep you much warmer than 1 500 watt convection
heaters. Yet, because it uses just 1 000 watts, it costs a third less to operate and could help you save money on electric bills.
A parabolic heater, coupled with other conservation measures, will help save energy in your home. For example, energy savings may
be realized by keeping the thermostat on your central heating system at a lower than normal setting and thereby decreasing the average
room temperature. Personal comfort can be maintained at these lower room temperatures by using a parabolic heater.
How your Presto
parabolic heater works
An automatic control switch, or thermostat, is built into the heater to control the heat output. The control knob, 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 notice-
able 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.
