INSTALLATION
These infrared heaters are designed for comfort heating. They
are to be permanently mounted to the wall or ceiling with the
fixture directed to the area to be heated. The unit is designed to
give years of safe, trouble-free operation when properly installed,
operated and maintained.
A. Site Selection:
The supporting structure where the heater is attached must have
adequate strength to safely support the heater. This heater has
been evaluated by UL for outdoor use only if mounted
underneath an overhang using a quartz tube heating element.
The heaters should not be mounted close to insulation, drapery
or similar materials which could come in contact with the cabinet
or heater guard. The heaters are intended for elevated mounting
locations so that they radiate down to the floor area. A mounting
height should be selected so that the heater has adequate
clearance to moving equipment and personnel, yet low enough to
deliver heat to the selected area. For heater weights and
minimum clearances, see tables 3 & 4:
TABLE 3:
Fixture Length Max

Bottom of heater to floor 6 ft (1.83 m)
Side or end of heater to wall 12 in (305 mm)
Heater to Adjacent Heater 36 in (914 mm)
Face of Heater to any
possible combustibles
Once an acceptable location has been determined, see the
following instructions to complete the mechanical installation:
B. Element Installation / Handling:
1. The heater fixture is shipped as an assembly with very
fragile quartz or metal sheathed heating elements
factory installed.
2. Replacement elements must be ordered separately to
be installed by a qualified person. See Section:
REPLACEMENT ELEMENT contained in this manual.
CAUTION: Do not handle the Quartz tube heating elements
with bare hands or with gloves that may have grease or oil
present.
C. Heater Mechanical Installation
Chain Mounting:
1. Fasten the two triangular mounting plates to

the fixture with the screws provided. The dimple hole
should be kept towards the top.
2. Cut suspension chain to the desired length.
3. Attach the chain to the heater triangular brackets using
“S” hooks. S-hooks must be closed to assure the
heater is permanently mounted. Ensure heating
element is horizontal.
4. If desired, tilt heater by adjusting chains as shown in
figure 1:

Bracket Mounting (Item HX-1025662):
The heaters may also be mounted by means of an optional
ceiling or wall mounting bracket as shown in figures 2, 3 &

6. For general guidance in replacing elements or
changing to an alternate wattage element see the
section titled “
REPLACEMENT ELEMENT”.
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.
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”
Adjacent heaters should be no less than 36”
(305mm) to any wall or ceiling surface.
(914mm) apart.
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.
D. 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.

Maintenance and repair described in this section must be
performed by qualified personnel only. Any other Maintenance
should be discussed or performed by an authorized service
representative. At a minimum, all maintenance tasks should be
performed annually before each heating season.
1. When doing any work on this heater disconnect the
electrical supply at the main branch circuit switch, and
lock the disconnect switch in the off (open) position.
Tag the circuit "Out for Maintenance" to prevent
potential lethal shock hazards.
2. This heater is hot when in use, make sure the heater
has completely cooled off before attempting any
Maintenance.
3. 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.
4. Check and Maintain the Clearance to Combustibles as
described in this manual.
5. Annually check the tightness of all visible screws, bolts
and nuts, in particular the support structure including
chains or bolts and nuts. Make sure the heater is
secure on all supporting points.
6. Check the wiring compartment for cleanliness. If
necessary, clean by using a vacuum or compressed
air.
7. The heater will operate at maximum efficiency when
the reflector and heating element are 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 5050 mixture of rubbing alcohol and water. Dry thoroughly
before energizing.
1a. Check Branch Circuit fuse or Circuit Breakers.
1b. Check the status of any controls.
