2.3.3 Flooring
The heater shall be installed on a level floor 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 (152
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
Lite2 heaters can be installed in the low-profile
top configuration as received from the factory, or with
an optional high wind vent cap.
Locate the heater in an open, unroofed area.
Do not install the heater under a deck.
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.

(In US-18 in (46 cm) clearance;
In Canada-24 in (61 cm) clearance)
Figure 2. Non-Combustible Platform.
Notes:
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
base.
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 build-
ing, even though the access might be through another
structure (e.g., a garage or utility room). In the United
States there must be a minimum of four (4) feet (1.22
m) horizontally or four (4) feet (1.22 m) vertically
between the heater exhaust point and any door, glass
opening, or gravity inlet to a building. In Canada, the
heater must be installed so that the exhaust point of the
heater is at least ten (10) feet (3.0 m) from any
building opening (see Figure 3).
