To obtain the maximum performance from your heater, we recommend the following be done at least once a
year:
1.
With an air hose regulated to 30 psi, blow off any dust and dirt from in front of the heater that has
accumulated on the reflective surfaces of the heater and reflective lens. Accumulated dirt degrades
performance by up to 10 percent.
2.
Blow off any accumulated dirt on the vent holes of the heater and make sure the lid is not bent such that
the vent area is reduced.
3.
When not installed or in use, store the heater in a dry, dust-free place and be sure the lens assembly is
protected from any possible damage.

5.0 Maintenance
6.0 Service and Troubleshooting
HotZone™ heaters have no moving parts and should provide years of trouble-free service.
6.1 Element Troubleshooting
At full power and after two to three minutes of warm-up time, the heater element should glow a warm orange
color, similar to the color of coals in a hot fire.
If the element does not warm up at all:
•
Is the service power on at the circuit breaker?
•
Is there a switch or dimmer in the circuit? Is the switch on?
•
Is the heater connected to the service in the heater's junction box? Turn off the power at the circuit
breaker to check the connections.
•
Are the fuses intact? Turn off the power at the circuit breaker to check the fuses.
•
Is the element in working condition? Burned out elements normally have visible burn marks on the face
of the element. If there is no evidence of damage, and you still suspect the element, turn off the power
at the circuit breaker, disconnect the service power and check element resistance. It should be between
10 and 50 ohms, depending on the element.)
•
Are the high temperature leads connected to the element? Turn off the power at the circuit breaker.
Remove the element from the heater housing and check the connections at the back of the element.
If the heater barely glows:
•
Is there a dimmer in the heater circuit? Is the dimmer turned full on and operating correctly?
•
Is the heater connected to the correct line voltage (under load condition) for its element type?
See Figure 3 or Appendix B.
•
Is the heater wired correctly for its element type? See Figure 3 or Appendix B.
•
Are all connections intact? Note that three phase devices where one leg is disconnected will operate
with reduced output.
