Installation, Operation, Maintenance Instructions & Spare Parts

WARNING. The BX convection heater is a heavy duty baseboard designed
for use in industrial environments and is not intended for use in residential

WARNIN G

and commercial locations. The heater is not thermally protected and air
flow obstruction with flammable materials could create a fire hazard. All
openings must be clear at all times.

A. INITIAL INSPECTION

1. Upon receipt from the carrier, inspect the heater for
possible damage in transit. If necessary, immediately
report damage to shipping company.

2. Verify that the nameplate voltage, phase, and wattage
are as ordered and are suitable for use on the electrical
power supply available. DO NOT CONNECT THE BX
CONVECTION HEATER TO AN ELECTRICAL SUPPLY
VOLTAGE OTHER THAN THAT SHOWN ON THE
PRODUCT NAMEPLATE.

3. The BX convection heater is CSA approved for operation
in non-hazardous areas only. Ensure that no hazardous
conditions exist before energizing the heater.

B. INSTALLATION

1. The BX convection heater is symmetrically designed and
CSA approved so that the electrical connection box can
be located at either end. Before attaching the universal
mounting legs, be sure to identify the end to be electrically
connected.

2. The BX is CSA approved as an industrial baseboard heater
for floor or wall mounting. A minimum distance of 90 mm
(3 1/2") must be maintained between the heater and walls
or floors. The universal mounting brackets (supplied) are
designed to provide this clearance.

NOTE: The BX heater weighs 45 lbs (21 kg). The wall supports

must be strong enough to carry this weight.

3. Attach the mounting brackets to the floor or wall. All
studs, bolts, nuts and other fasteners shall be secured
so that there is no possibility of loosening over prolonged
periods. These must be inspected at regular intervals and
retightened when necessary.

4. See Figure 1 – Floor Mount or Figure 2 – Wall Mount.,
page 3 for bracket mounting details.

4.1 Remove the two screws located on the front panel.

4.2 Remove the heater front panel.

4.3 Back off the screws on the universal mounting legs

enough to allow penetration of the screw heads
through the keyhole openings in the back of the
heater.

4.4 Slide the heater assembly to the side so that the

mounting screws engage the keyhole openings.

4.5 Tighten the mounting screws to secure the heater to

the mounting brackets.

4.6 The electrical connection box is exposed upon

removal of the heater front panel, allowing for
electrical connections to be made at this time. See
Section C. Electrical Connections, page 4 for
electrical suggestions.

4.7 Thermostat - If the heater selected is equipped

with a built-in thermostat, see Figure 3, page 3
for final mounting. The thermostat is connected
electrically, but the sensing bulb and capillar y tube
must be secured into the final mounting position
as shown. The simple final assembly will ensure
good temperature control. Be certain not to “kink”
the capillary tube or crush the sensing bulb during
installation.

C. ELECTRICAL CONNECTIONS

1. Verify that the heater nameplate voltage and supply
voltage are the same (see A.2, page 2).

2. Select the proper electrical conductor size rated at 194°F
(90°C) (Canadian Electrical Code). The connection box
volume is 5200 cm³.

3. The control cabinet of the BX convection heater is
constructed to EEMAC 1 standards. Combination 1/2" ­3/4" knockouts are provided for easy connection.

4. The BX convection heater is completely prewired internally.
Connect the power conductors and control conductors to
the terminations as illustrated on the wiring diagram enclosed.

5. The schematic wiring diagrams shown below illustrate the
BX convection heater with various control options. Some
of this equipment is optional and may not be included with
your BX heater.

6. Replace the front panel after all wiring is completed and
before turning on the electrical disconnect switch.

D. TEMPERATURE CONTROL

1. BUILT-IN Thermostat - Heaters with a factor y installed
thermostat are prewired and require only power

connection. The thermostat sensing bulb must be

assembled into its final position. See B.4.7. for final
assembly.

2. The thermostat supplied is a high quality device with a
factory calibrated range of 50 to 104°F (10 to 40°C). Due
to the proximity of the sensing bulb to the heater, the
actual thermostat setting will not be the same as the

desired room ambient temperature. This is normal with all

unit mounted thermostats. It should be a simple matter to
find the setpoint to provide the desired comfort level.

3. REMOTE LINE VOLTAGE THERMOSTAT - A remote
thermostat rated to operate on full voltage may be

desired. Installation and wiring of the selected thermostat

must comply with the manufacturer’s instructions.
CCI Thermal Technologies Inc. can supply appropriate
thermostats.

E. MAINTENANCE

WARNING. The BX convection heater is constructed to

operate in tough industrial applications with minimum

WARNIN G

maintenance. However, some routine maintenance is
recommended to extend the life of the heater and its
components. ALWAYS DISCONNECT THE
ELECTRICAL SOURCE BEFORE PERFORMING ANY
MAINTENANCE.

1. TERMINAL ENCLOSURE - The periodic intervals, but
not more than once a year, open the terminal enclosure
to inspect for cleanliness and dampness. Vacuum any

dust and wipe up any moisture. Check all electrical
connections and tighten if necessary.

2. HEATER PAINT FINISH - The BX convection heater
is finished with a heav y duty enamel paint to provide
maximum resistance to corrosion due to air-born

contaminants. We recommend the cabinet to be wiped
down periodically using a mild detergent.
