MOUNTING LIMITATIONS
Unit heaters should not be used in potentially explosive atmospheres. The finish is
not intended for direct salt spray exposure in marine applications or the highly
corrosive atmospheres of swimming pools, chemical storage bins, etc.
Do not install unit heaters above recommended maximum mounting height.
Obstructions must not block unit heater air inlet or discharge. Heaters must be
mounted at least 7' above the floor to prevent accidental contact with the heating
element or fan blade which could cause injury.

enclosure shall be phosphate coated to resist corrosion and finished in a durable polyester powder coat finish.
Mounting brackets designed for either ceiling or wall swivel mounting shall be furnished as shown on the heating
schedule.
Heaters shall be of the draw-through air flow design to eliminate the element hot spots and extend design life.
Fans shall be aluminum, directly connected to fan motor, and designed specifically for unit heater application.
Low voltage control 24 volt transformers shall be standard on models 7.5 KW and greater (Optional 120V), to
allow safer more precise temperature control.
Individual optional field installable control kits shall be available for all models. All controls shall have pig tails and
spade terminals for ease of wiring to centrally located terminal board. All heaters of 63 amperes or less shall be
provided with power disconnect switches (field installed kits or factory installed).
All heaters shall be UL Listed and meet the requirements of the National Electrical Code.
For safety, the electric heating bank shall consist of metal sheath heating elements. The elements shall consist of
80/20 Nichrome wire encased in refractory material (MGO) and have a copper clad steel sheath for strength and
corrosion resistance, and aluminum fins for faster heat transfer. Automatic reset thermal overheat protection shall
be of the linear capillary type wired for instantaneous de-energizing in case of the thermal overload. Heating bank
to have protective air inlet louvers.
All heaters drawing in excess of 48 amperes shall be provided with factory installed subdivided and fused circuits

ARCHITECT’S AND ENGINEER’S SPECIFICATIONS*
The heating equipment shall include an electric automatic
fan forced air heater suitable for small area heating, as
manufactured by Berko®, a Marley Engineered Products®
Brand, Bennettsville, SC. The heater shall be designed for wall
mounting, recess or surface. Heaters shall be cETLus listed.
BACK BOX: The back box shall be designed as a recessed
rough-in box in either masonry or frame installations and is
also used when surface mounting frames are used in surface
mounting installations. The back box shall be heavy gauge
galvanized steel and shall contain knockouts through which
power leads enter.
INNER FRAME ASSEMBLY: The heater assembly, which fits
into the back box, shall consist of a heavy gauge steel fan
panel to which all of the operational parts of the heater are
mounted. The inner frame assembly shall be completely pre-
wired.
HEATING ELEMENT: The heating element shall be of the
non-glowing design consisting of an 80/20 nickel-chromium
resistance wire enclosed in a steel sheath to which plate fins
are copper brazed. The element shall cover the entire air
discharge area to ensure uniform heating of all discharged air.
It shall be warrantied for 5 years.
ON/OFF SWITCH: A double-pole, single throw on/off switch
shall be mounted on the back box for positive disconnect of
power supply. It will be completely concealed behind the
front cover.
MOTOR AND CONTROLS: The fan motor shall be impedance
protected, permanently lubricated. Fan control shall be of
the bi-metallic, snap-action type and shall activate fan after
heating element reaches operating temperature, and continue
to operate the fan after the thermostat is satisfied and until
all heated air has been discharged. The thermostat shall be
single-pole type on all models. Thermal cutout shall be self-
hold (manual-reset) type designed to shut off heat in the event
of overheating. The fan shall be four-bladed aluminum. A back-
up (End of Life) thermal fuse shall be provided for additional
safety.
SURFACE MOUNTING FRAME: The surface mounting frame
shall be of heavy gauge steel designed to mount around the
back box for a finished surface installation. Slot knock outs
shall be provided for power supply conduit.
FRONT COVER: The louvered front cover shall be of heavy
gauge steel with a powder paint finish. A plug button will be
provided to replace the thermostat knob and render the unit
tamper-resistant.
FINISH: All sheet metal parts, except the galvanized steel
back box, shall be phosphatized, then completely painted by a
powder paint process.
