1.2 Consumer Information and Safety
The Lite2 Pool/Spa heater is designed and
manufactured to provide many years of safe and
reliable service when installed, operated and maintained according to the information in this manual and
the installation codes referred to in later sections.
Throughout the manual safety warnings and cautions
are identified by the "
comply with all of the warnings and cautions.
1.2.1 Spa/Hot Tub Safety Rules
The following “Safety Rules for Hot Tubs,”
recommended by the U.S. Consumer Product
Safety Commission, should be observed when
using the spa.
" symbol. Be sure to read and
WARNING
WARNING
The U.S. Consumer Product Safety
Commission warns that elevated water
temperature can be hazardous. Consult heater
operation and installation instructions for water
temperature guidelines before setting
temperature.
AVERTISSEMENT
La U.S. Consumer Product Safety Commission
indique que des températures de l’eau élevées
peuvent être dangereuses. Voir la notice
d’installation et de fonctionnement pour le
réglage de la température.
1. Spa or hot tube water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for
a healthy adult. Special caution is recommended
for young children.
2. The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and
subsequently result in drowning.
3. Pregnant women take note! Soaking in water
above 102°F (38.5°C) can cause fetal damage
during the first three months of pregnancy
(which could result in the birth of a braindamaged or deformed child). If pregnant women
are going to use a spa or hot tub, they should
make sure the water temperature is below 100°F
(38°C) maximum.
4. The water temperature should always be checked
with an accurate thermometer before entering a
spa or hot tub. Temperature controls may vary by
as much as 4F° (2C°).
5. Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.
AVERTISSEMENT
Les Règlements suivants pour Cuves
Thermales, tel que recommandés par la
Commission U.S. de Sécurité des Produits
pour les Consommateurs, devraient être
respectés lors de l’utilisation du spa.
6. Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.
7. Prolonged immersion in hot water can induce
hyperthermia.
Hyperthermia occurs when the internal body
temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and
Page 2
an increase in the internal body temperature. The
effects of hyperthermia include:
• Lack of awareness of impending hazard
• Failure to perceive heat
• Failure to recognize need to leave spa
• Physical inability to leave spa
• Fetal damage in pregnant women
• Unconsciousness resulting in a danger of drowning
1.2.2 Swimming Pool Energy Saving Tips
Water Pik Technologies offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without
sacrificing comfort.
1. The American Red Cross recommends a maximum water temperature of 78°F (25°C). Use an
accurate pool thermometer. A difference of 4F°
(2C°) , between 78°F and 82°F (26°C and 28°C),
will use as much as 40% more gas.
2. Carefully monitor the water temperature of your
pool in the summertime. You can reduce heater
usage due to warmer air temperatures.
3. Find the proper setting on the pool heater temperature control and use the TEMP-LOK to
discourage further adjustments.
4. Set the filter time clock to start the pump no
earlier than 6:00 AM during the pool heating
season. This is the time when nightly heat loss
balances.
5. If the pool is only going to be used on weekends,
reduce the heater temperature control setting by
8 or 10 degrees during the week. Reset it to the
desired temperature level a day or so before you
plan to use the pool.
6. During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found on the inside of
the heater.
7. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other landscaping, cabanas, or fencing.
8. Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on filter systems.
1.3 Warranty
The Lite2 heater is sold with a limited factory
warranty. Details are specified on the back cover of
this manual.
Make all warranty claims to an authorized Jandy
representative or directly to the factory. Claims must
include the heater serial number and model (this
information can be found on the rating plate), installation date, and name of the installer. Shipping costs are
not included in the warranty coverage.
The warranty does not cover damage caused by
improper assembly, installation, operation or field
modification. Also, damage to the heat exchanger by
corrosive water, is NOT covered by the warranty. See
Section 8.1 for maintaining proper pool water chemistry.
NOTE: Keep this manual in a safe place for
future reference when inspecting or servicing
the heater.
1.4 Codes and Standards
The Lite2 pool and spa heater is design certified
by CSA (Canadian Standards Association) as complying with the latest edition of the “Standard for Gas
Fired Pool Heaters”, ANSI Z21.56 in the USA and
CSA-4.7 in Canada.

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 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 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.
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

AVERTISSEMENT
Lorsque vous installez l’appareil de chauffage,
assurez-vous que l’ouverture d’aération se
trouve à un minimum de 10 pieds (3,05 m) de
toute ouverture d’un bâtiment.
The top surface of the heater must be at least
three(3) feet above any forced air inlet, or intake ducts
located within ten(10) feet horizontally.
If the heater is installed under an overhang, there
must be a minimum clearance of 5 feet (1.5 m) above
the top of the heater and the structure should not
overhang the heater more than 12 inches (0.30m). The
area under the overhang must be open on three sides.
This prevents combustion gases from being diverted
into living areas through doors, windows, or gravity
inlets.

If the heater is installed close to a structure,
protect it from rain water runoff with rain gutters on
the roof or other measures. Do not locate the heater
near irrigation sprinkler systems that could spray water
on it. Water from sprinklers may cause damage to
controls and electronic components.
Avoid locations where wind deflection off nearby
structures might cause downdraft conditions. Where
downdraft conditions exist, locate the heater at least 3
feet (0.91 m) from vertical surfaces (e.g., nearby
buildings and walls). The addition of a vent cap may be
necessary.
In Florida it is required that the heater be securely fastened to the equipment pad. Use a size
1/4" x 1-1/2" long stainless steel Tapcon® type concrete screws and washers at each of the four tabs
located at the base of the heater. Mounting the
appliance in this manner meets the applicable requirements of the Florida Building Code.
Mounting screws are not provided with this
heater. After placing the heater on the equipment pad,
drill a hole in the concrete at each of the four tabs on
the feet of the heater. (The correct size drill bit is
usually provided with the concrete screws when
purchased). Place a screw in each of the holes and
fasten the heater to the equipment pad (see Figure 4).
Do not over torque the screws.

2.3.5. Indoor and Outdoor Shelter
Installations
An outdoor shelter (Canada only) is an unoccupied enclosure which does not communicate directly
with occupied areas. All indoor installations and
outdoor shelter installations require the addition of a
factory approved drafthood. The drafthood must be
installed without modification and in accordance with
all local, state, provincial and national codes.
Une remise extérieure (au Canada seulement)
est un endroit inoccupé qui ne communique pas
directement avec les endroits occupés. Toutes les
installations intérieures et remises extérieures exigent
l’addition d’une coupe-tirage intérieur approuvée par
le manufacturier. La coupe-tirage intérieur doit être
installée sans aucune modification et selon les
exigences fournies par le manufacturier.
These codes, standards and Water Pik Technologies require that the heater be properly vented as
outlined in this manual. Proper ventilation of exhaust
and combustion air are essential for the safe and

efficient operation of the heater (See Section 3). An
approved draft hood may be purchased from your local
Jandy distributor. See Section 11 (Parts List) of this
manual for the correct part number for you model and
size heater.
In general, these requirements specify that the
room in which a heater is installed should be provided
with two permanent air supply openings; one within 12
inches (305mm) of the ceiling, the other within 12
inches (305mm) of the floor. All indoor installations
must have openings to outside air for combustion,
ventilation, and dilution of flue gases from inside the
building (see Figure 5 and Table 3). Water Pik Technologies does not recommend indoor installations that
do not provide combustion air from outside the building.
All outdoor shelter installations (Canada only)
must have uninterrupted openings to outside air for
combustion and ventilation. The installation must be in
accordance with the latest edition of CAN/CSAB149.1. Water Pik Technologies does not recommend
outdoor shelter installations that depend on internal air
for combustion. Combustion air should be ducted to the
heater from outside the structure.
Outside Air Supply: When combustion air is
supplied directly through an outside wall, each opening
should have a minimum free area of one square inch
per 4,000 BTU/h (1.2kW) input of the total input rating
of all appliances in the enclosed area. If air is provided
through horizontal ducts, each opening and duct must
provide one square inch of flow area for each 2000

Venting
BTU/h (0.6 kW). These requirements are summarized
in Table 3. Note that the areas specified are net free
areas and should be increased by 50 percent when the
openings are covered by screens, louvers, grills or
3.1. Combustion Air Supply
other protective covers (see Figure 5 and Table 3).
The heater location must provide sufficient air
supply for proper combustion and ventilation of the
surrounding area as outlined in the latest edition of
ANSI standard Z223.1 or in Canada, CAN/CSAB149.1, and any local codes that may be applicable.
Note: In Canada, follow Canadian Standard,
CAN/CSA-B149.1 or local codes.
Exhaust Fans or Vents: Any equipment which
Model LG Pool and Spa Heater
exhausts air from the room where the heater is
installed can deplete the combustion air supply or
reverse the natural draft action of the venting system.
This could cause flue products to accumulate in the
room. Additional air must be supplied to compensate
for such exhaust.
The information in Table 3 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by
qualified engineers.
If a blower or fan is used to supply air to the
room, the installer should make sure it does not create
drafts which could cause nuisance shutdowns of the
pilot.
The heater must be completely isolated and
protected from any source of corrosive chemical
fumes such as those emitted by trichlorethylene,
perchloroethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other
corrosive material near combustion air
openings or in the room. Avoid locating dryer
vents in the vicinity of combustion air openings.
Failure to prevent corrosive materials from
mixing with combustion air can result in
reduced heater life and unsafe heater
operation.
AVERTISSEMENT
N’entreposer aucun produit chimique, produit
nettoyant ou produit corrosif à proximité des
bouches d’air de combustion ou dans la pièce.
Éviter de placer des tuyaux de ventilation pour
sécheuse à proximité des bouches d’air de
combustion. Le fait de laisser des matières
corrosives se mélanger à l’air de combustion
risque de réduire le cycle de vie de l’appareil
de chauffage et de compromettre son
fonctionnement.

3.2.2. Indoor and Outdoor Shelter
Installations
WARNING
Vent pipe diameter must be as required by the
National fuel Gas Code ANSI Z223.1 or the
Canadian Installation Codes for Gas
Appliances CAN/CSA-B149.1. Undersize pipe
can result in inadequate venting and oversize
pipe can result in vent condensation. In either
case the result can be release of combustion
products to the indoors. This can cause
serious injury or death by carbon monoxide
poisoning or asphyxiation.
AVERTISSEMENT
Le diamètre des tuyaux de ventilation doit
répondre aux exigences du National Fuel Gas
Code ANSI Z223.1 ou du code canadien des
installations des appareils à gaz CAN/CSAB149.1. Des tuyaux trop petits risquent
d’entraîner une ventilation inadéquate et des
tuyaux trop gros risquent de provoquer une
condensation dans les tuyaux. Dans un cas
comme dans l’autre, des produits de
combustion risquent de s’échapper dans le
bâtiment et causer des blessures graves ou
l’asphyxie par le monoxyde de carbone.
All indoor installations and outdoor shelter
installations require the addition of a factory approved
drafthood. The drafthood must be installed without
modification.
All vent installations must be made in accordance
with all local, state or provincial codes and with:
1. Chapter covering "Venting of Equipment" of the
national Fuel Gas Code, ANSI 223.1 latest
edition , or the applicable provisions of the local
building codes.
3.2 Vent Pipe Sizing and General
Installation
3.2.1. Outdoor Installations
For outdoor installations, exhaust venting
considerations will determine the placement of the
heater (See Section 2.3.4). If the heater cannot be
placed so as to meet the requirements stated in Section
2.3.4, a vent pipe and cap may be added to the heater
to move the exhaust vent opening to a position that
complies with the requirements. When the heater is
installed in areas of high wind or when unavoidably
installed near a vertical obstruction where
downdrafting may occur, it may be desirable to add a
vent cap directly to the top of the heater. In all cases,
vent pipes and caps must be of the same diameter as
the exhaust outlet of the heater. Approved vent caps
may be obtained through your Jandy distributor.
2. In Canada , CAN/CSA-B149.1.
Avoid long horizontal runs of the vent pipe, and
90° elbows, reductions and restrictions. Horizontal runs
should have at least a 1/4 inch rise per foot (20mm
per meter) in the direction of flow.
Avoid terminating heater vents near air conditioning or air supply fans. The fans can pick up exhaust
flue products from the heater and return them inside
the building, creating a possible health hazard.
Do not locate the vent terminal where flue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air flow to
and from vent terminal. Do not terminate the vent
under decks, stairways, or car ports.
Be sure to support all venting so that connections
Page 10
will not separate and so that the weight of the vent
pipe does not rest on the heater draft hood. All connections should be made with rustproof sheet metal
screws. Do not weld or fasten the vent pipe to the
heater draft hood. The draft hood and heater top must
be easily removable for normal heater service and
inspection.
The draft hood outlet is to be connected to an
unobstructed vent pipe of the same diameter, terminating outside the building. The vent must terminate at
least two (2) feet (0.61 m) above the highest point of
the roof or other object that is within ten (10) feet
(3.05 m) of the vent termination. The vent pipe must
have a listed vent cap which allows a full equivalent
opening for flue products (see Figure 5). The top of
the vent cap must be at least five feet in vertical height
above the drafthood outlet.
Type “B” double wall or equivalent vent pipe is
recommended. However, single wall metal vent pipe
may be used as specified in the latest edition of the
National Fuel Gas Code ANSI Z223.1 or in Canada
CAN/CSA-B149.1
IMPORTANT NOTE: Do not use sheet metal
screws at the snap lock joints of Type B gas
vents.
WARNING
The Lite2 pool and spa heaters are designed
for use with either natural gas or LP gas.
Check the rating plate on the inner panel to be
sure that the heater is configured to use the
type of gas being supplied. DO NOT

1. Gas piping installation must be in accordance
with the latest edition of ANSI Z223.1 and all
local codes. In Canada, the installation must be in
accordance with CAN/CSA-B149.1 and all local
codes that apply.
When venting multiple appliances through one
common duct, each appliance must have it’s own vent
temperature limit switch. All vent limit switches must
be wired in series so as to prevent any appliance from
firing in the event of a blocked vent. Refer to ANSI
Z223.1 or, in Canada, to CAN/CSA-B149.1 for more
information on multiple venting.
3.2.3 Inspection and Replacement of
Existing Vent System with New
Components
If the Lite2 is being installed to replace an
existing pool heater, it is recommended that a new
appropriate venting system be installed with the new
heater. However, if an existing venting system must be
used, be sure to carefully inspect the venting system to
ensure that it is in good condition and continues to be
appropriate for the Lite2 heater. Replace any parts
that are not in good and serviceable condition with new
parts before completing the pool heater installation.
SECTION 4.
Gas Connections
4.1 Gas Supply and Piping
Review the following general instructions before
continuing the installation.
2. Check the gas supply to be sure that it is the
same as the gas indicated on the heater’s rating
plate. Lite2 LG heaters, as shipped from the
factory, are certified to operate within the
altitude range indicated on the rating plate. If a
field conversion to a different altitude range
should be necessary, manifold kits are available
for changing the altitude range of the heater. See
Table 1 in section 1.7.1 of this manual to determine the correct altitude designation for your
heater. Refer to Section 11 “Parts List” to order
the correct part number of the manifold kit
needed. When changing the altitude range of the
heater, be sure to fill out the altitude conversion
label, included in the kit. Apply the label on the
inner panel of the heater, next to the original
rating plate.
CAUTION
Permanent damage to the gas valve will occur
if the following procedures are not followed.
ATTENTION
