2.0 PRE-INSTALLATION

2.1 Initially, inspect the heater for possible damage
due to shipping and handling. Claims for shipping
damages shall be placed with the carrier.

2.2 Check the heater nameplate to ensure that

the heater area classication and temperature

code are suitable for the hazardous area

classication. For details of hazardous

locations with potential for explosion, refer
to the Canadian Electrical Code or National
Electrical Code.

2.3 Check to ensure that the heater voltage is the
same as the supply voltage.

2.4 The heater must be installed by qualied
personnel in strict compliance with national and
local electrical codes.

DO NOT CONNECT THE HEATER TO AN
ELECTRICAL SUPPLY VOLTAGE OTHER THAN

WARNING

THAT SHOWN ON THE PRODUCT NAMEPLATE.

3.0 INSTALLATION - GENERAL REQUIREMENTS

3.1 The XPA heater is intended for industrial use
and is to be mounted in an enclosure. The
main function of this heater is to prevent the
damaging effects of moisture and condensation
on the components inside the enclosure. It is not
intended for comfort heating use.

3.2 XPAL and XPAS heaters are approved for
enclosure mounting either horizontally or side
mounted with the junction box at the side (refer

to Table 2). XPAR heaters are approved for

vertical mounting only with the junction box at the

bottom. Ensure that the enclosure is sufciently

strong to support the heater which, depending
on the model, could weigh up to 15 lbs (7 kg).

3.3 Do not recess the XPA heater into the wall. Use
the bracket supplied with the unit to ensure
that the minimum spacing from the wall of
1” (25 mm) is maintained.

3.4 If more than one heater is being installed,
maintain at least 3” (76 mm) between adjacent
heater extrusions.

3.5 The XPA heater relies on natural convection
and “black heat” radiation to transfer heat to
the surroundings. See TABLE 1 for minimum
clearances above heater.

4.0 MOUNTING BRACKET INSTALLATION

4.1 Install heater with the supplied hardware

in accordance with the Figures and
instructions below (Figure 14 and 15).

XPAL & XPAS Heaters

Step 1: Scribe lines into the mounting surface
signifying the top and side of the mounting
bracket, indicating where the mounting bracket

will be located after installation (Figure 4 and
Figure 5).

3.6 Maintain a 3” (76 mm) clearance and NEVER LESS
THAN 1” (25 mm) clearance in front of and at the
sides of the heater.

3.7 The XPAL and XPAS heater relies on vertical

convective ow through its ns to operate properly.

The unit must be mounted in the horizontal or

side mount orientation, as applicable. Under no

circumstance can the heater be mounted vertically
on its end with the junction box on the top or bottom

and the at n surfaces in a horizontal position. The
XPAR heater must be mounted vertically with the
junction box at the bottom. Refer to Figures 11, 12 &

13 for allowable mounting orientations.

THE HEATERS SURFACE IS HOT WHEN
THE HEATER IS ENERGIZED. KEEP ALL
COMBUSTIBLES AWAY FROM THE HEATER

CAUTION

AND MAINTAIN THE RECOMMENDED
INSTALLATION CLEARANCES AT ALL TIMES.

Step 2: Remove the mounting bracket from the
heater and install it to the mounting surface,
aligning the bracket with the scribe marks from

Step 1 (Figure 6).

FIGURE 6 - INSTALL THE MOUNTING BRACKET

Step 3: Secure the heater to the bracket by
tightening the provided Socket Head Cap
Screws into the threaded holes on each end of

the heater (Figure 7).

FIGURE 7 - ATTACH MOUNTING BRACKET TO HEATER ITSELF

XPAR Heaters

Step 1: Scribe a mark into the mounting
surface indicating where the top part of
the mounting bracket will be located after

installation (Figure 8).

FIGURE 8 - SCRIBE THE TOP OF THE MOUNTING BRACKET

Step 2: Measure down 0.625” (16 mm) from the
scribed mark and scribe a mark for the top bolt
location. Measure an additional 5.5” (140 mm)
from the top bolt location to indicate the bottom

bolt location (Figure 9). Drill holes at the marked

locations for the mounting bolts.

NOTE: Proper use of supplied mounting bracket will
ensure minimum distance of 1” (25 mm) from the
mounting surface.

NEVER INSTALL ONE HEATER ABOVE
THE OTHER.

TO ENSURE SAFE OPERATION, HEATER MUST

slide the mounting bracket under the head of
the supplied bolts. Position the heater onto the

mounting bolts and tighten securely (Figure 10).

5.0 WIRING

5.1 Whenever hazardous materials are present,

ensure that the junction box covers are secure

before energizing the heater. Follow all applicable

national and local codes for hazardous location
installation. The XPA heater is available with
a terminal housing. A terminal housing may
be required by national and/or local codes for
hazardous locations.

5.2 Use supply wires suitable for 221°F (105°C).

5.3 Use approved conduit and conduit seals as

required by the national and local codes for
hazardous locations.

5.4 To provide maximum protection, each XPA
heater should be fused individually using

HRC fuses.

5.5 All heaters come factory prewired ready
for direct connection to power supply leads

(see Figure 16).

(i) Connect the power leads to terminals

marked L1 and N or L2.

(ii) Connect the ground wire to the ground

connection located in the heater junction
box cover.

5.6 Replace junction box cover securely. Do not

over-tighten.

6.0 WIRE GUARD (OPTIONAL)

6.1 Install wire guard by inserting wire arms into

holes on heater ns.

7.0 START-UP

7.1 If the unit contains a junction box ensure the
junction box lid is securely installed onto the
terminal housing.

7.2 Check to ensure that all plugs, screws, and
covers are securely in place.

7.3 Check associated electrical equipment.

7.4 Check that all wall mounting bracket connections
are tight.

7.5 Turn on supply power.

7.6 If the unit is equipped with an adjustable
thermostat, dial the temperature
required by twisting the thermostat knob.

TO PREVENT UNSAFE OPERATION OF THE
HEATER DO NOT EXCEED THE MAXIMUM

WARNING

ALLOWABLE AMBIENT OPERATING
TEMPERATURE OF 104°F (40°C).

8.0 MAINTENANCE

8.1 Check the following before every heating season:

WARNING

CAUTION

CAUTION

WARNING

FIGURE 16 - WIRING DIAGRAM -

XPA CONVECTION HEATER

WHENEVER HAZARDOUS MATERIALS ARE
PRESENT, ENSURE THAT THE TERMINAL
HOUSING COVERS, PLUGS, ETC., ARE
SECURED (BUT NOT OVER-TIGHTENED)
BEFORE ENERGIZING THE HEATER.

ALL CIRCUITS MUST BE IN THE OPEN
POSITION BEFORE REMOVING JUNCTION OR
TERMINAL BOX COVERS.

USE SUPPLY WIRES SUITABLE FOR 221°F
(105°C). SUPPLY WIRES ARE TO BE FUSED
WITH APPROPRIATELY SIZED HRC FUSING.

USE APPROVED CONDUIT AND CONDUIT
SEALS AS REQUIRED BY HAZARDOUS
LOCATION STANDARDS.

WARNING

DISCONNECT POWER FROM THE
HEATER BEFORE PERFORMING ANY
MAINTENANCE. FAILURE TO DO SO CAN
RESULT IN PROPERTY DAMAGE, INJURY
OR DEATH.

(i) Remove junction box cover and inspect

the electrical connections. Ensure the
connections are tight and wires are not
burned or frayed.

(ii) Inspect the heater and its surroundings.

Make sure that heater clearances are
maintained and no debris is around the

heater or stuck in the ns.

(iii) Check all mounting hardware and ensure

fasteners are tight.

(iv) Replace the cover securely and turn on the

power supply.

CAUTION

ENSURE THAT NO POWER IS CONNECTED
TO THE EQUIPMENT PRIOR TO MAKING
ANY CONNECTIONS.

9.0 REPAIRS

9.1 If the heater malfunctions, and is no longer
operating, send the heater to the factory for
servicing. Do not attempt to service the unit.

9.2 When returning the heater you can ll out the
online repair form at http://www.ccithermal.com/

online-repair-form.php or include the following

information with the heater when shipping:

• Company name and address

• Contact name

• Telephone/fax number/email

• Product model and serial numbers

• Tagging codes

• Advise if an estimate is required prior to

starting the repair

• P.O. Number

• Description of problem(s) and/or

required repairs

• Special instructions (if applicable)

• Return shipping instructions

10.0 TROUBLESHOOTING

ONLY OPEN THE JUNCTION BOX IF IT IS SAFE

WARNING

TO DO SO!

10.1 These heaters contain a thermal fuse. If the
unit is not operating within proper constraints,
the unit may have overheated, causing the
thermal fuse to open. Check the thermal fuse by
disconnecting the power, opening the junction
box and measuring the resistance across the

terminals. If the resistance is innite, the fuse

has been triggered and the unit must be sent to
CCI Thermal Technologies Inc. for repair.

NOTE: If your circuit contains a thermostat and the
ambient temperature is high enough to turn off the

thermostat, the measured resistance will be innite,

this test will not check the thermal fuse.
