Model LJ Pool and Spa Heater
Page 5
Check the rating plate on the heater or the Parts
List (Section 10) of this manual for the correct Jandy
draft hood or vent cap part number. See instructions
supplied with the draft hood or vent cap for installation
and attachment. When the draft hood is used, locate
the heater so as to be in the same atmospheric pres-
sure zone as the combustion air inlet to the heater.
2.3 Location Requirements
2.3.1 Introduction
WARNING
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide
in flue gases which could result in severe injury,
or death.
Caution
When pool equipment is located below the pool
surface, a leak from any component can cause
large scale water loss or flooding. Water Pik
Technologies cannot be responsible for such
water loss or flooding or resulting damage.
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 down
drafts, 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 1).
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 floor of non-
combustible 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 consist-
ing 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 10) 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 (76.2
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.

Note: Clearances listed in
Table 1 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 1, use the
greater value to ensure
safe operation.
