4. Confirm that the proper elements have been installed and
that the electrical power supply matches the marked voltage
and amperage rating by referencing tables 1 & 2 in the
“Heating Element Selection Charts” section of this manual.
Heaters are rated for single phase, 50/60 Hz power.

5. Proper installation of the heater requires that an adequate
grounding conductor be connected to the ground terminal.
This terminal marked by a green colored screw head and is
located on the inside of the wiring compartment.
6. Connect supply conductors to heating element leads and
confirm all connections are securely tightened. Remove any
foreign objects from the control box and attach the cover.
7. See section titled “OPERATION” before energizing the
heater.

For the 61” heater, the mounting brackets should be mounted
with the flanges facing outward and the heater triangular brackets
located on the inward side as shown in figure 4:
OPERATION
1. Check to make sure the mechanical and electrical
installation is complete and that it is safe to operate the
heater.

2. Set the field supplied temperature controller to a setting
above the current room temperature.
3. Energize the heater electrical supply circuit.
4. The heater should come on.
5. Check out and report any unusual or questionable
operating characteristics, such as noise, smoke, etc.
6. Set the temperature controller to the desired room
temperature setting and place the heater in service.
MAINTENANCE
Maintenance and repair must be performed by qualified
personnel only.
The fixture can be directed into the area being heated by
adjusting the mounting brackets.
At a minimum, all maintenance tasks should be performed
annually before each heating season.
CAUTION: When directing the heater, care must be exercised to
prevent adjacent surfaces from overheating. In no case, should
any part of the heater be less than 12” to any wall or ceiling
surface. Adjacent heaters should be no less than 36” apart.
1. Inspect all connections and conductor insulation for damage,
looseness, fraying, etc., as applicable. Tighten any loose
connections and replace or repair wire with damaged or
deteriorated insulation.
CAUTION: The heater must always be mounted with the quartz
tube in a horizontal position. This will prevent the coiled
resistance wire from sagging and potentially failing. 2. Annually check the tightness of all visible screws, bolts and
nuts, in particular the support structure bolts and nuts.
3. Check the wiring compartment for cleanliness. If necessary,
clean by using a vacuum or compressed air.
CAUTION: The heater must not be recessed.
4. The heater will operate at maximum efficiency when the
reflector and heating element is kept clean. The reflector can
be removed by snapping out one edge and rotating. Most
dust and dirt can be removed by washing the reflector and
heating elements with a 50-50 mixture of rubbing alcohol
and water. Dry thoroughly before energizing.
C. Heater Electrical Installation:
Follow these instructions to complete the electrical installation:
1. External branch circuit protection is required. See heating
element ratings and follow Code recommendations.
2. Follow the NEC and any local electrical and building codes
related to the installation and intended use of the heater.
3. When doing any work on this heater, including the initial
electrical connection, disconnect the electrical supply at the
main branch circuit switch, and lock the switch in the off
(open) position. Tag the circuit "Out for Maintenance" to
prevent potential lethal shock hazards.
