Unless heaters are installed over 12 ft. high, it is generally recommended that all radiant heaters be mounted on an
angle to assure that radiant warmth is distributed from the sides rather than straight down on the heads and shoulders
of the people being warmed.
· Install fixture to heat the area from the “cold side” if possible. This
helps compensate for increased body heat losses due to exposure.
· Warm floors reradiate heat. Warmer air rises from floor. Some
heat reflects from floor. Mounting a heater directly over a table
or other obstruction will block the energy, primarily heating the
object. It is best to move heater to the side, allowing complete
body and floor coverage.
· When outdoors, hang heater under protective roof or weather
cover whenever possible.
· Even though heater is all-weather construction, it will last longer
and look better if it is protected from rain and snow.
· Angle fixture 30º to 60º from horizontal face down.
· Best angle is approximately 45º.

PROBLEM
Heater does not glow
A 240 V element connected to 110 V or 208 V will warm, but not glow orange, or generate
sufficient heat for typical applications. (Matching your Voltage is extremely important).
If element is visibly orange, but there is insufficient heat, refer to the areas covered, with
respect to conditions and mounting heights.
Replace or clean dirty or non reflective reflectors.
Disconnect power and check element with Ohm meter for continuity. If there is any con-
tinuity across the bulb, the problem is in the wiring/controls.
Check that there is proper voltage to the heater.
Check that the control/switch is working.
Check main power circuit breaker.
Check wiring for a loose connection or burned wire.
WHAT TO DO
Check supply voltage to confirm it matches voltage of heating element.
