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 firing 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
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
or asphyxiation from carbon monoxide in flue gases
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).

Installation & Operation Manual
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.
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
from the gas meter to the heater. When sizing gas
lines, calculate three (3) additional feet of straight
pipe for every elbow used.

Notes:
•
Numbers are for natural gas (0.65 Sp. Gr.) based on 1/2
inch (3.45 kPa) water column pressure drop. Check supply
pressure with a manometer, and local code requirements
for variations. For LP gas, reduce pipe diameter by one
size, but maintain a minimum 3/4 inch diameter.
•
Check supply pressure and local code requirements before
proceeding with installation.
•
Consider pipe fittings when determining gas pipe sizing.
•
Table shows the minimum supply gas pipe size required.
Larger pipe size can be used if required by local code or
if desired.
•
It is critical that the incoming gas supply pressure at the
heater is within the maximum and minimum pressure
requirements. If the range of acceptable supply pressure
is not provided, the gas supply system to the heater must
be modified to meet pressure requirements.

Supply Gas Pipe Size Requirements*
2.
Check the gas meter to make sure it will supply
enough gas to the heater and any other appliances
using the same heater.
NOTE: The gas line from the meter is usually larger than
the gas valve. Therefore, you will need to reduce
connecting pipe as necessary. Make this reduction as
close to the heater as possible.
3.
Install a manual gas shutoff valve for service and
safety.
