Radiant Heating Elements
The radiant heating elements consist of spiral-
wound resistance wire attached to micro porous
insulation with molded ceramic fi ber walls in a
corrosion protected metal tray. A thermal limiter is
attached to the tray.
The thermal limiter is a temperature limit/hot light
switch attached to the heating element tray. The
glass tube and metal rod extend across the center
of the element. The rod's expansion and contraction
operate the contacts inside the switch.
The temperature limit/hot light switch performs two
functions:
Turns on the HOT LIGHT when the glass tube 1.
and metal rod temperature exceeds 150°F. The
hot light will remain on until the glass tube and
metal rod temperature has cooled below 150°F
(even after the surface unit switch has been
turned off).
Detects when the glass temperature above a 2.
unit has exceeded its limit of approximately
1031°F and disconnects power to that
unit. When the glass temperature cools
below 1031°F, the unit will turn back on. The
temperature limit/hot light switch cannot be
calibrated.
Note: A surface unit pilot (element on indicator)
light, located over the top of each surface unit
selector knob, will turn on immediately when the
surface unit is turned on. The light will remain on
until the surface unit is turned off.
