INSTALLATION
C.1
General Requirements
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.
2.
XPAL and XPAS heaters are approved for enclosure
mounting either horizontally or side mounted with the
junction box at the side. 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.
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.
4.
If more than one heater is being installed, maintain at
least 3" (76 mm) between adjacent heater extrusions.
5.
The XPA heater relies on natural convection and "black
heat" radiation to transfer heat to the surroundings. See
Table 1, page 4 for minimum clearances above heater.
