PROBLEM
Heater does not glow
Low heat output
Heater does not work
WHAT TO DO
TROUBLESHOOTING
Unless heaters are installed over 12' [3.7 m] 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 xture to heat the area from the “cold side” if possible.
This helps compensate for increased body heat losses due
to exposure. Warm oors reradiate heat. Warmer air rises
from oor. Some heat reects from oor. 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 oor
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 xture 30º to 60º from horizontal face
down. Best angle is approximately 45º.
LOCATION SUGGESTIONS
OUTDOORS
INSTALLATION DIRECTIONRECOMMENDED POSITIONING
▪ Check supply voltage to conrm it matches voltage of heating element.
▪ A 240V element connected to 110V or 208V will warm, but not glow orange
or generate sufcient heat for typical applications [Matching your voltage is
extremely important]. If element is visibly orange, but there is insufcient
heat, refer to the areas covered with respect to conditions and mounting heights.
▪ Replace or clean dirty or non reective reectors.
▪ Disconnect power and check element with ohm meter for continuity. If there is
any continuity 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.
