Avoid placing the heater in locations where it can
cause damage by water or condensate leakage. If this
is not possible, provide a suitable drain pan to catch
and divert any leakage. The pan must not restrict the
air flow around the heater.
All criteria given in the following sections reflect
minimum clearances as stated in the national stan-
dards. However, each installation must also be evalu-
ated, taking into account the prevailing local conditions
such as wind speed and direction, proximity and height
of walls that may block ventilation or cause
downdrafts, and proximity to public access areas.
2.3.2 Clearances
The heater must be placed to provide clearances
on all sides for maintenance and inspection. There
must also be minimum distances maintained from
combustible surfaces (see Table 2).
At least 20" (500mm) access must be available in
front of the heater for burner removal.
If the heater is to be installed in a garage, or
similar structure, all burners and burner ignition
devices must have a minimum 18" (457mm) clearance
above the floor.
This heater must be installed at least 5 feet (1.3
meters) from the inside wall of the pool or spa unless
the heater is separated from the pool or spa by a 5 foot
high solid fence, wall or other permanent barrier.
Ce chauffe-piscine doit être installé á au moins 5
pieds (1.52m) de la paroi interne de la piscine à moins
d'être isolé de la piscine par une clôture, un mur ou
autre barrière permanente.
2.3.3 Flooring
The heater must be installed on a level surface
of noncombustible construction or on fire-resistant
slabs or arches. Noncombustible flooring is defined as
flooring material and surface finish not capable of
being ignited and burning and with no combustible
materials against the underside. Acceptable materials
are those consisting entirely of a combination of steel,
iron, brick, tile, concrete, slate, glass or plaster. Do not
install the heater directly on a combustible wood or
carpet floor without placing a noncombustible platform
between the floor and the heater.
The heater can be installed on a combustible
floor if a noncombustible base assembly, available
from Jandy, is used. See the heater rating plate or the
Parts List (Section 11) of this manual for the appropri-
ate base part number. Heaters must never be
installed directly on carpeting.
As an alternative to the Jandy noncombustible
base plate, in the United States, the National Fuel Gas
Code allows a heater to be placed on a combustible
surface when there is a platform under the heater
made of hollow masonry no less than 4 inches (102
millimeters [mm]) thick, covered with sheet metal at
least 24 gauge thick and extending beyond the full
width and depth of the heater by at least 6 inches (153
mm) in all directions. The masonry must be laid with
ends unsealed, and joints matched to provide free
circulation of air from side to side through the masonry
(see Figure 2). If the heater is installed in a carpeted
alcove, the entire floor of the alcove must be covered
by a noncombustible panel.
Table 2. Minimum Heater Clearances From Combustible Surfaces
Note: Clearances listed in Table 2
are manufacturer's tested values.
These are given as minimum
values. Where local and national
codes apply, and values are
different than those listed in
Table 2, use the greater value to
ensure safe operation.

1. Blocks must provide solid base and be braced so they
cannot slip out of place.
2. Air openings in blocks must be arranged to provide
unrestricted opening through entire width or length of
