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

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 Figure 11–
Figure 13, page 5 for allowable mounting orientations.
CAUTION. The heater's surface is hot when the heater
is energized. Keep all combustibles away from the
heater and maintain the recommended installation
CAUTION
clearances at all times.

Mounting Bracket Installation: XPAL & XPAS
Heaters
Install heater with the supplied hardware in accordance with
the figures and instructions below (Figure 14 and Figure 15,
page 6).
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, page 4)
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
4 4
scribe marks from Step 1 (Figure 6, page 4)

Mounting Bracket Installation: 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 5, page 4).
Figure 8 – Scribe the drop 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, page 4).
Drill holes at the marked locations for the mounting
bolts.
