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 rst three (3) 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 1F° (1C°).
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.
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 an
increase in the internal body temperature. The effects of
hyperthermia include:
1.3.1 Spa/Hot Tub Safety Rules
WARNING
The following “Safety Rules for Hot Tubs,”
recommended by the U.S. Consumer Product Safety
Commission, should be observed when using
the spa.
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.
1. Spa or hot tub 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.
• 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
1.3.2 Swimming Pool Energy Saving Tips
Zodiac Pool Systems, Inc., offers the following
recommendations to help conserve fuel and minimize
the cost of operating your pool heater without sacricing
comfort.
®
1. The American Red Cross
recommends a
maximum water temperature of 78°F (26°C). Use
an accurate pool thermometer. A difference of 4F°
(2°C), 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 Set Point Lockout
feature to discourage further adjustments.
4. Set the pump 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 78°F
(25°C) 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 lter systems.

1.5 CerticationCodesandStandards
The heater is design-certied by CSA (Canadian
Standards Association) compliant with the latest edition of
the Standard for Gas Fired Pool Heaters, ANSI
in the USA and CSA 4.7 in Canada.
All Jandy Pro Series heaters must be installed in
accordance with the local building and installation codes
as per the utility or Authority Having Jurisdiction (AHJ).
In the absence of local codes, refer to the latest edition of
the following national codes for installation:
®
Z21.56
1. In the United States, the National Fuel Gas Code,
®
NFPA
54/ANSI Z223.1. Pay particular attention
to the chapter addressing Venting of Equipment.
2. In Canada, the Natural Gas and Propane
Installation Code, CAN/CSA-B149.1. Minimum
combustion air requirements MUST be
followed for proper and safe operation. The
Jandy Pro Series JXi heater may not operate
properly when installed with only the minimum
combustion air openings allowed in CAN/
CSA-B149.1.
The JXi pool and spa heaters meet or exceed the
requirements of energy conservation regulations, such as
those in California, Hawaii, New York, Oregon and other
states that have disallowed the use of continuously lit pilot
type ignition sources. In addition, the natural gas models
of this heater comply with the California South Coast Air
Quality Management District's (SCAQMD) Rule 1146.2
for Nitrogen Oxide (NOx) emissions.
Any changes to the heater, gas controls, air orice, gas
orices, wiring, draft diverter, or improper installation
may void the warranty. If change is required to any of the
above, consult the factory.
1.6 General Operation Description
In the JXi heater, the blower draws air and fuel through
specially designed orices for both air and gas, then
delivers the precise mixture to the burner located inside
the combustion chamber. The combustion chamber
is completely sealed and contains the heat exchanger,
which surrounds the burner. Once combustion gases pass
through the heat exchanger, the ow is directed through
an exhaust duct located on the side of the combustion
chamber, where it vents to the atmosphere.
1.7 Safety Controls
The JXi heater is equipped with the following safety
controls to protect internal components and prolong the
life of the heater.
Air Flow Switch
The air ow switch monitors the vacuum (negative
pressure) within the blower housing. The air ow switch
is factory set and the ignition module will not operate
unless the air pressure switch and all safety switches are
satised.
Water Pressure Switch
Operating the heater without sufcient water ow may
severely damage the heater. If water ow to the heater is
restricted, the water pressure switch prevents the burner
from ring. The control panel will display an error
message to indicate water ow is insufcient.

Page 5
NOTE: If the heater is installed below the level of the pool,(or
more than two feet above the pool level), the pressure
switch setting must be adjusted. See Section 5.4
Adjusting the Water Pressure Switch for guidelines.
Water Temperature Control
All heater models are equipped with an electronic control
which senses water temperature by means of a thermistor
and controls heater operation to bring the water to the
temperature selected. It has an option for two (2) separate
thermostat settings which are typically used to set pool and
spa temperatures.
Ignition Control
The ignition control provides energy for ignition of the air/
gas mixture, monitors the ame and controls the gas valve.
When the temperature control calls for heat, the ignition
control initiates the start-up process by rst purging the
combustion chamber gases. The ignition control will
then energize the igniter and open the gas valve when
the igniter surface is sufciently hot. During the start-up
process and after ignition, the ignition control system is
continually monitoring the ame condition. If the control
senses an unstable ame it will close the gas valve as a
safety precaution.
2.2 Materials Installer Must Provide
For ALL Installations
• The correct size gas pipe to supply gas from gas meter to
heater (see Section 4.1).
• Gas shut-off valve to be installed in gas line outside of the
heater jacket.
• Manual gas shut off valve must be installed in an
accessible location, within 6’ upstream of heater.
• A suitable gas union joint to connect heater to gas line
outside of heater.
• Plumbing materials for providing sediment trap (drip leg)
in gas line between the manual gas valve and heater (see
Section 4.1).
• 120 VAC or 240 VAC power supply. (A junction box is not
needed at the heater; connections are made inside of the
heater jacket.)

2.4 Heater Components
1. Gas Valve - The gas valve controls gas ow
into the burner. It enables ow only when the
temperature control requires heat and only if
all safety controls enable operation. It is also a
negative pressure regulator, where it maintains a
gas pressure of 0.2” WC below the the air pressure
at the blower inlet. It regulates the gas pressure to
0.2” WC less than the air pressure at the blower
inlet. This is necessary for proper operation of the
burner system and cannot be accomplished with
common (positive pressure) gas valves.
2. Combustion Blower and Air Orice – The
blower pulls air and fuel gas in through their
respective orices and mixes the two gases before
forcing the fuel/air mixture through the burner
for combustion. During normal operation the fan
will turn on before ame initiation to ensure that
the combustion chamber is clear before the igniter
is energized. Additionally, the fan will run after
the ame is extinguished in order to clear the
combustion chamber of exhaust gas.
3. Pool/Spa Water Temperature Control - The
JXi heater models are equipped with an electronic
control, which senses water temperature by means
of a thermistor and controls heater operation to
attain and maintain the water according to the
temperature selected. It has an option for two (2)
separate thermostat settings, which are typically
used to set pool and spa temperatures.
4. Ignition Control - The ignition control provides
energy for ignition of the air/gas mixture, monitors
the ame and controls the gas valve. When the
temperature control calls for heat, the ignition
control provides a pre-purge of the combustion
chamber. Once the pre-purge is complete the
ignition control then applies electrical power to
a hot surface igniter. When the igniter attains
sufcient temperature, the ignition control opens
the gas valve. Immediately after ignition, the
control system will look for characteristics of a
stable ame and de-energize the igniter. If ame
is not detected shortly after opening the gas valve
the control system will close the valve to prevent
further gas release. The ignition control will
attempt to start 2 more times before an ignition
fault is displayed.
5. Igniter - The hot-surface igniter is constructed of
a ceramic material that attains a temperature great
enough to ignite the air/fuel mixture, when an
electric current is applied.

6. High Limit Switches - Two (2) limit switches -
one at the heat exchanger rst pass (135°F/57°C)
and one at the heat exchanger outlet (150°F/65°C)
-- prevent water of excessive temperatures from
being discharged from the heater. If either switch
senses excessive temperature, the gas valve will
close and combustion will stop.
7. Water Pressure Switch - Operating the heater
without sufcient water ow may severely
damage the heater. This control senses whether or
not water is available to the heater by measuring
back pressure at the header inlet. If the pool
water pump fails or the water lter is blocked, the
pressure switch prevents operation of the burner.
The display will indicate a no ow fault to alert
you that water pressure is insufcient.
NOTE: If the heater is installed below the surface level of the
pool,(or more than two feet above the pool level), the
pressure switch setting must be adjusted. See section
5.4 Adjusting the Water Pressure Switch.
8. Vent Temperature Limit (240°C/464°F)- This
is a single use switch, which detects abnormal
temperatures in the vent system. It is mounted
to the exhaust duct. Excessive temperatures
will cause the switch to open. Excessive
temperatures can be caused by inadequate water
ow or a compromised heat exchanger. The vent
temperature limit switch will open the safety
circuit which shuts off the gas valve and shuts
down the heater. If this limit is activated/tripped,
the heater cannot be safely operated without rst
determining the cause and without replacing the
limit switch with an exact replacement.
9. Air Pressure Switch - The air pressure switch
monitors the vacuum (negative pressure) within
the blower housing. This switch veries that air
is owing through the combustion system by
sensing pressure. It shuts off the heater if air ow
is inadequate.
2.5 Dimensions
See Figure 1 for exterior dimensions and dimensions to
critical connections.
2.6 Clearances
In both indoor installations (US) and outdoor shelter
installations (Canada), the heater must be placed to
provide clearances on all sides for maintenance and
inspection, as well as maintain minimum distances from
combustible surfaces.
NOTE Clearances are manufacturer’s tested values. These
are given as minimum values. Where local and national codes
apply, and if the clearance values specified in the applicable
codes are different that those listed in this manual, use the
greater value to ensure safest operation.

3.3 Vent Pipe Sizing and Installation
The JXi may be installed with venting as a Category I or
Category III appliance.
• Category I: A Category I appliance is a vented
appliance that operates with a non-positive vent static
pressure and with a vent gas temperature that avoids
excessive condensate production in the vent. Category
I installations are vented vertically and terminate at
the roof.
• Category III: A Category III appliance is a vented
appliance that operates with a positive vent static
pressure and with a vent gas temperature that avoids
excessive condensate production in the vent. Category
III installations can be vented via a side wall.
In all installations (Category I and Category III):
• Avoid terminating heater vents near air conditioning
or air supply fans. Fans can pick up exhaust ue
products from the heater and return them inside the
building, creating a possible carbon monoxide or
other health hazard.
• Selection of vent pipe type and material must be
carefully considered depending on the type of
installation. Zodiac strongly recommends using high
quality vent pipe materials, which are corrosion

Precautions Against Common Venting:
Seek the assistance of a Registered Professional Engineer
for proper design of a common venting system.
Zodiac Pool Systems, Inc. does not recommend using
a common vent to vent multiple appliances through a
common duct. However, if no other option is deemed
available by the installer, each appliance must have its
own vent temperature limit switch. All vent limit switches
must be wired in series so as to prevent any appliance
from ring in the event of a blocked vent. An outside
draft inducer must be installed to pull and create negative
®
pressure in the vent system. Refer to ANSI
Z223.1 or
in Canada CAN/CSA B149.1 for more information on
common venting multiple appliances. Do not connect
vent systems of different categories to the same venting
system.
WARNING
Improper installation or maintenance can cause nausea
orasphyxiationfromcarbonmonoxideinuegases
which could result in severe injury, or death. For indoor
installations, as an additional measure of safety, Zodiac
Pool Systems, Inc. strongly recommends installation
of suitable Carbon Monoxide detectors in the vicinity of
this appliance and in any adjacent occupied spaces.
3.3.4 Inspection and Replacement of Existing Vent
System with New Components
When replacing an existing pool heater with the JXi, it
is recommended that a new appropriate venting system
is installed with the new heater. However, if the existing
venting system must be used, be sure to carefully inspect
the existing system to ensure that it is in good condition
and appropriate for the JXi heater. Replace any parts that
are not in serviceable condition before completing the
installation.
Section 4. Gas Connections
4.1 Install Piping and Check Gas Supply
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.
The heater must be isolated from the gas supply piping
system by closing the individual manual shut off valve
during any pressure testing of the gas supply piping
system at test pressure equal to or less than 1/2 psi
(3.5kPa).
The heater and its individual shut off valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psi (3.5 kPa).

WARNING
The JXi pool and spa heaters are designed for use
with either natural gas or LP gas. Check the rating
plate on the front of the combustion chamber to be
sure that the heater is designed to use the type of gas
being supplied. DO NOT ATTEMPT TO CONVERT
THIS HEATER FOR USE WITH ANY OTHER TYPE
OF FUEL OTHER THAN THE FUEL TYPE FOR
WHICH IT WAS CONFIGURED AT THE FACTORY
AND WHICH IS MARKED ON THE NAMEPLATE.
CAUTION
Permanent damage to the gas valve will occur if the
installation procedures are not followed correctly.
1. Refer to Table 4 for correct gas inlet piping length
