Efficient Operation: The five-bladed alu-
minum fan and the rugged impedance-
protected, totally-enclosed motor, achieve
efficient operation.
Phosphatized, Baked Enamel Finish: All sheet
metal and extruded aluminum parts, except the
back box, are phosphatized, then finished by a
baked enamel electrostatic painting process.
Elements: Steel fins are
copper-brazed to low-watt
density, steel-sheathed,
tubular heating elements
which are arranged in a
uniform grid pattern. The
grid covers the entire intake
area, resulting in uniform
heating of all discharged air.
Type FFCH-RE enclosures also mount easi-
ly into standard 2 x 2 ceiling grids
FFCH SERIES
COMMERCIAL DOWNFLOW CEILING MOUNTED HEATERS
APPLICATIONS
Type FFCH ceiling-mounting fan-
forced heaters are designed for
commercial and industrial areas
requiring electric fan-forced heat.
Capacities are 2,000 to 5,000 watts.
Type FFCH-SE surface enclosures are
designed to mount flat on the ceiling
and extend only six inches into the
room. Type FFCH-RE enclosures
have no protrusions outside the
recess box, allowing the heater to
recess only seven inches into ceiling
space. Mounts into permanent ceiling
with trim ring.
FEATURES
BUILT-IN FAN DELAY Space
temperature is controlled by a wall or
unit-mounted thermostat. When the
thermostat calls for heat, the heating
elements and fan energize. When the
thermostat is satisfied, the elements
shut off, but the fan continues to
operate until all of the heated air is
discharged. This feature avoids
exposing the heater to residual heat,
thus achieving a high comfort level
and longer component life.
ZBL-BFFCH
(03-02)
AUTOMATIC THERMAL CUTOUT
A thermal cutout shuts off the heater in
the event of over-heating and
reactivates the heater when the
temperature returns to normal.
MULTIPLE PHASE HEATERS The
208 and 240 volt heaters can be field
converted from single to three-phase
operation. 277 volt single-phase
heater is also available.
MULTIPLE WATTAGE HEATER
SECTIONS The 5,000 watt heater
can be field converted to 3,800 watts
or 2,500 watts, and the 4,000 watt
heater is convertible to 3,000 or 2,000
watts.
THUMB PINS align and temporarily
hold the enclosure cover to the
heating section freeing
both hands to finish
installation.
Deliver heat where you want it...
in vestibules, hallways, work-
shops, restrooms and entry ways. Totally adjustable airfloweven from 14 ft. ceilings!

Wide pattern
In standard ceiling applications (8 to 10), heater
disperses the air to give a gentle, less pronounced
pattern while circulating all the air from floor to ceiling.
Narrow pattern
For high ceiling applications (11 to 14), fan concen-
trates the heated air to ensure full penetration to the
floor level.
Asymmetrical pattern
Heated air is directed in a specific direction, allowing
the heater to be located where space allows, with
the heated air delivered to where it is required.

10 ARCHITECTS & ENGINEERS SPECIFICATIONS*
The heating equipment shall include an electric, ceiling-mounted
type FFCH, Series 500 fan-forced air heater suitable for large
area heating as manufactured by Berko, A Marley Engineered
Products Brand, Bennettsville, SC. The heater shall be UL
Listed. The heater shall be designed for surface, recess or T-Bar
mounting. For surface mounting a Berko FFCH-SE surface
enclosure shall be used. For T-Bar mounting a Berko FFCH-RE
recess enclosure shall be used. For recessed mounting in a
permanent ceiling a Berko FFCH-RE recess enclosure and
FFCH-TK trim kit shall be used. The heaters shall be factory
wired for single-phase operation and field convertible to three-
phase operation by removing one jumper wire, and relocating
one wire. The heaters should be factory wired for full wattage
and field convertible to 75% or 50% wattage by the removal of
one or two wires respectively.
HEATER SECTION: The heater section shall consist of 20
gauge steel chassis on which are mounted the heating
elements, fan motor and blade, fan control, thermal cutout and
3-pole contactor. Heater section shall be completely prewired.
HEATING ELEMENTS: The heating element shall be
guaranteed for five years and shall be non-glowing design
consisting of 80/20 NiCh resistance wire, enclosed in a steel
sheath, to which steel plate fins are brazed. The elements shall
cover the entire air intake area to ensure uniform heating of all
discharged air.
MOTOR AND CONTROLS: The fan motor shall be impedence-
protected, permanently lubricated and with totally-enclosed
rotor. Fan control shall be bi-metallic, snap-action type and shall
activate fan after the heating element reaches operating
temperature, and continue to operate the fan after the
thermostat is satisfied and until all heated air has been
discharged. Thermal cutout shall be bi-metallic snap-action type
designed to automatically shut off the heater in the event of
overheating and reactivate the heater when the temperature
returns to normal.
OPERATIONAL CONTROLS: Thermostat, disconnect switch
and all interlock relays shall be installed within the heater
enclosure.
RECESS ENCLOSURE: The back box shall be designed for
