This heater has been designed, tested and manufactured to
give the most reliable performance practical. Each unit is given
a final check before shipping to assure that every component is
correctly wired and operating properly. The safe and depend-
able operation of the heater depends upon proper installation,
therefore the manufacturer will not assume responsibility for
equipment installed in violation of any code or standard.
MOUNTING
The heater can be mounted in either of two positions as shown
in figures 2 and 4 and as designed for control box accessibility,
mounting space, etc. The control compartment cover requires
14” clearance for opening.
Themountinghandle is shippeddisassembled. Itis to bemounted
to the appropriate side of the cabinet, as shown in figures 2 or 4,
using the screws provided which thread into weld nuts on the
cabinet. The heater then may be mounted using the optional
accessory wall bracket or supported from the ceiling using bolts
or chains attached through 2 holes provided in the handle. If the
heater is to be mounted as shown in figure 4, the louver assem-
bly may be repositioned to direct the air stream as desired by
removing the 3 attachment screws, pulling the assembly off,
and reinstalling the desired position.
ELECTRICAL WIRING
See diagram posted inside control compartment. The amperage
load and the minimum recommended wire size is listed at the
field wiring terminal for each power supply circuit.
The NEC requires that overcurrent protection and
supply wiring for electric heating equipment be rated at least
125% of the full amp-load of the circuit.
All supply wiring shall conform to the latest edition of the NEC
and to local codes having jurisdiction. Conduit openings are
provided in the back of the wiring compartment (See figure 3).
Make sure all field wiring connections are properly made and
are tight.
ELECTRICAL GROUND
This heater must be grounded before operating as required by
the National Electric Code and by applicable local codes. Use
a conductor of the appropriate size, secured to the ground lug
in the heater and to a grounded connection in the service
panel.
THERMOSTAT
The thermostat should be located where it will sense the free
air movement within the structure. It should not be positioned
or located in direct sunlight or where it will be affected by a
localized heat source such as lighting or other heaters. If wall
mounted thermostat is used, it should normally be mounted 5
feet above the floor. It should be connected to the control
terminal block in the heater as shown on the wiring diagram
and per instructions packed with the thermostat. All control
circuitry must be per NEC class 1 wiring.
Whereone or twowallsareexposed tooutsideenvironment in
smaller building areas, a single unit placed like this may be
sufficient.
Larger building areas may require muliple units installed like
this, especially where three or more walls are exposed to
outside environment. Units should be arranged for providing
perimeter air circulation where the air stream of one supports
thatofanother.
