RISK OF FIRE / EXPLOSION
This heater should not be used in potentially explosive atmospheres. Do not use in areas where gasoline,
paint or flammable liquids are used or stored.
Keep electrical cords, drapery, furnishings, insulation and other combustibles at least 3 feet (0.9m) from the
front of the heater and away from the sides, rear and top.
Installation minimum clearances specified both on the heater nameplate and in the owner’s manual must
be maintained.
Do not use as a residential or household heater.
The air heaters are designed for comfort heating and
should not be used in ambient temperatures
exceeding 104ºF (40ºC). They are to be permanently
mounted to the wall or ceiling for either horizontal or
vertical discharge. The unit is designed to give years
of safe, trouble-free operation when properly
installed and maintained.
A. Site Selection:
The Heaters should not be mounted close to
insulation, drapery or similar materials which could
come in contact with the cabinet, or block the inlet or
outlet of the heater. The heaters are intended for
elevated mounting locations so that they blow warm
air down to the floor area. A mounting height should
be selected so that the heater is out of the way of
possible moving equipment or personnel, yet low
enough to deliver warm air to the selected area. See
the mechanical installation section for recommended
installation heights.
Heater airflow should be directed to areas of greatest
heat loss. In general, greater numbers of small
heaters will provide more uniform and even heat
distributions than a few large ones. In order to help
move heated air around the room, multiple heaters
should be spaced out and direct air in a circular
pattern around the room perimeter such that each
heater supports the next heater’s airstreams.
Additional vertical discharge heaters with appropriate
diffusers can be located to direct heated air to the
room center and offset any ceiling heat losses. See
the figures below for some typical airflow pattern
arrangements:
Large room with exposed walls and roof –both
horizontal and vertical discharge heaters:
Large room with exposed walls and roof -
only horizontal discharge heaters:
Small room with one exposed wall –horizontal

B. Mechanical Installation:
These heaters may be mounted for either horizontal
or vertical discharge by means of threaded rods
(supplied by others). The heaters may also be
mounted by means of an optional mounting kit which
includes a bracket and cantilever arm which allows
horizontal pivoting of the heater. Lock washers
should be used on all mounting nuts and bolts to
ensure they don’t vibrate or work loose due to fan
vibration or other vibration transmitted to the heater.
The supporting structure that the heater is attached
to must have adequate strength to safely support the
heater. The heater dimensions and maximum unit

Do not attempt to service or clean heater while unit is operating as there is a hazard from electric
shock, injury from operating fan blade and burns from hot heating elements.
The unit heater may be operated normally at ambient
temperatures of 104°F (40°C) or less. Each heater
contains a normally open bimetal cutout which delays
the fan motor until the heating elements have
warmed up and also keeps the fan running after
shutdown until the heating elements have cooled
down.
A. Initial Operation:
Confirm proper mechanical and electrical installation
before operation of the heater.
1.) Heaters without built on or remotely mounted
fan switch:
a.) Set the temperature control thermostat to a
setting above the current room
temperature.
b.) Energize the heater electrical supply circuit.
c.) The heater should come on and the fan
should start within approximately 1 to 2
minutes.
d.) During normal operation the limit controls
are not supposed to cycle the heater ON and
OFF. If frequent cycling of the limit occurs,
verify the minimum mounting clearances are
maintained, verify proper orientation of the
room thermostat and there is no visible
obstruction to the heater inlet or outlet. If
this does not eliminate the limit control
cycling then the heater must be examined
by qualified service personnel before further
operation to determine the cause.
e.) Heaters may be provided with a manual
reset limit control (Optional with order code
M for heaters less than 10KW). This limit
control disables the electrical function of the
heater whenever excessive temperatures
are present. If the manual reset limit
control is suspected of causing heater non-
function then the heater must be
disconnected from the heater electrical

1. Inspect all terminal connections, contactor and
conductor insulation for damage, looseness,
fraying, etc., as applicable. Tighten any loose
terminals and replace or repair wire with
damaged or deteriorated insulation. If contactor
contacts are badly pitted, welded together, or
burned, replace the contactor.
2. If reduced heat output is suspected, perform the
mechanical checks. If low heat output is still
suspected after completing the mechanical
checks, verify the condition of the heating
elements by visual inspection and by using an
amperage meter to check the current draw of
each input line. Adjust the room thermostat to its
highest temperature to ensure all stages of heat
are energized. All input lines should draw
approximately equal current which should agree
with the nameplate rating. If they do not, one or
more of the heating elements could be burned
out and should be replaced.
B. Mechanical:
1. Annually check the tightness of all visible bolts
and nuts, in particular the support structure bolts
and nuts. Similarly check the motor mounting
bolts located in the top and back of the heater
case.
2. Periodically, check the motor, fan, discharge
openings, intake openings, heating elements and
control compartment for cleanliness. If necessary,
clean by using a vacuum or compressed air. Be
careful not to bend the fan blade propeller.
3. Check motor and fan for smooth running
operation. Any unusual noise or vibration must
be investigated and rectified.
