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
(1.52m) from the inside wall of a pool unless the
heater is separated from the pool by a solid fence, wall
or other permanent solid 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 (NFPA 54 / ANSI Z223.1), and in Canada, the
Natural Gas and Propane Installation Code (CAN/
CSA-B149.1), allow 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.
2.3.4 Outdoor Installation
The LX or LT Low NOx heaters can be installed
in the outdoor configuration as received from the
factory.
Locate the heater in an open, unroofed area. Do
not install the heater under a deck. Do not locate the
heater below or adjacent to any doors, glass openings,
louvers, grills, etc., which connect in any way with an
inhabited area of a building, even though the access
might be through another structure (e.g., a garage or

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.

Notes:
1. Blocks must provide a 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
base.
3. Sheet metal must be at least 24 ga. and extend 6"
beyond the heater jacket on all sides.
