Gas-Fired Pool & Spa Heater

Installation & Operation Manual
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 filter systems.
1.4 Warranty
This heater is sold with a limited factory warranty. Details
are included with this heater.
Make all warranty claims to a Zodiac
®
dealer 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.
NOTE
Keep this manual in a safe place for future
reference when inspecting or servicing the heater.
1.5 Certification Codes and Standards
The heater is design-certified by CSA (Canadian
Standards Association) compliant with the latest edition of
the
Standard for Gas Fired Pool Heaters,
ANSI
®
Z21.56
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:
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 orifice, gas
orifices, 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 orifices 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 flow 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 flow switch monitors the vacuum (negative
pressure) within the blower housing. The air flow switch
is factory set and the ignition module will not operate
unless the air pressure switch and all safety switches are
satisfied.
Water Pressure Switch
Operating the heater without sufficient water flow may
severely damage the heater. If water flow to the heater is
restricted, the water pressure switch prevents the burner
from firing. The control panel will display an error
message to indicate water flow is insufficient.
