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 sufficiently
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.

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 flow through its fins 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 flat fin 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.
CAUTION
THE HEATERS SURFACE IS HOT WHEN
THE HEATER IS ENERGIZED. KEEP ALL
COMBUSTIBLES AWAY FROM THE HEATER
AND MAINTAIN THE RECOMMENDED
INSTALLATION CLEARANCES AT ALL TIMES.
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).
FIGURE 4 - SCRIBE THE TOP OF THE MOUNTING BRACKET
FIGURE 5 - SCRIBE THE SIDE OF THE MOUNTING BRACKET
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).
