similar structure, all burners and burner ignition de-

2.3.3

Flooring

The heater must be installed on a level surface
of noncombustible construction or on fi re-resistant
slabs or arches. Noncombustible fl ooring is defi ned
as fl ooring material and surface fi nish 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 fl oor without placing a noncombustible platform
between the fl oor and the heater.
The heater can be installed on a combustible fl oor
if a noncombustible base assembly, available from
Jandy, is used. See the heater rating plate or the Parts
List (Section 11) in this manual for the appropriate
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 com-
bustible 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

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 unre-
stricted 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.

carpeted alcove, the entire fl oor of the alcove must be
covered by a noncombustible panel.

Outdoor Installation

The LXi heater can be installed in the outdoor
confi guration 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
utility room). In the United States the vent system
shall terminate at least 4 ft (1.2 m) below, 4 ft (1.2 m)
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.
