INSTALLATION
For the 61"
) heater, the mounting brackets should be
(1549 mm
mounted with the flanges facing outward and the heater
triangular brackets located on the inward side as shown in figure
4:

The fixture can be directed into the area being heated by
adjusting the mounting brackets.
CAUTION: When directing the heater, care must be exercised to
prevent adjacent surfaces from overheating. Do not direct one
heater towards another. In no case, should any part of the
heater be less than 12"
(305mm)
Adjacent heaters should be no less than 36"
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.
CAUTION: The heater must not be recessed.

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.
4.
Heaters are rated for single phase, 50/60 Hz power.
5.
Confirm that the electrical power supply matches the
marked voltage and amperage for the heating element
which has been factory installed.
The heating element installed in the unit is
indicated either on the nameplate or on a
separate label adjacent to the nameplate.

7.
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.
8.
Each heater is equipped with two high-temperature
silicone lead wires for connection to the power circuit.
Connect supply conductors to these two wires and
confirm all connections are securely tightened. Remove
any foreign objects from the control box and attach the
cover.
9.
See typical wiring schematic below. In cases where
property damage may result from malfunction of the
heater a back-up system or temperature alarm should
be used.
10. Use 75ºC minimum copper conductors for wiring.
11. See section titled "OPERATION" before energizing the
heater.
