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

Step 3: Pre-install the mounting bolts onto the mounting surface allowing enough clearance to 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.

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.
