M O U n T i n g
1. The heater must be permanently mounted in a level,
upright position for operation. See Figures 2, 3, and 4
for maximum tilt angles, installation clearances, and
physical dimensions.
For ease of installation, a variety of mounting kits are
available from the factory.
2. The mounting structure must be strong enough to:
a.
support the heater’s weight (refer to the
“Specifications” section),
b.
provide sufficient stiffness to prevent
excessive vibration, and
c.
withstand abusive situations such as
transportable installations.

W A R n i n g
Disconnect the power supply before installation of the heater. Lock the switch in the “OFF” (open) position and/or tag the
switch to prevent unexpected power application. installation and wiring of the heater must adhere to all applicable codes.
g E n E R A L
1. Use only copper conductors and approved explosion-proof means of wiring to make connections to the heater. Refer to the
“Technical Data” table and heater data plate for conductor rating.
2. External overcurrent protection is required. Refer to the “Technical Data” table and heater data plate for voltage, amperage,
and phase. Supply voltage is to be within 10% of the data plate voltage.
F i E L D W i R i n g
1. Supply conductors, ground conductor, and room thermostat conductors (see note 2 below) pass through the 1” nPT opening
(see Figure 5) and are to be wired into the control enclosure (see Figure 6).
