Precautions Against Common Venting
Seek the assistance of a Registered Professional Engineer
for proper design of a common venting system.
Zodiac 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 Z223.1 or Australian standards applicable
to Gas Pool Heaters, AS4560, AS/NZS 5601 for more
information on common venting multiple appliances.
Do not
connect vent systems of different categories to the
same venting system.
3.3.6
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
Gas piping installation must be in accordance with the
latest edition of ANSI Z223.1 and the Australia standard
installations, AS/NZS 5601.1 along with all local codes.
• Pressure Testing
: 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 greater than or equal to 3.5 kPa (.5 psi).
CAUTION
Permanent damage to the gas valve will occur if the installation
procedures are not followed correctly.
WARNING
CONVERTING THIS HEATER FOR USE WITH ANY OTHER
FUEL TYPE IS NOT RECOMMENDED BUT, WHEN NECESSARY,
SHOULD ONLY BE PERFORMED BY A LICENSED AND QUALI-
FIED PROFESSIONAL, AND ONLY AFTER CONTACTING ZODIAC
GROUP AUSTRALIA FOR THE PROPER INSTRUCTIONS AND
CONVERSION KIT.
All questions should be directed to the Zodiac customer service
center at 1300 763 021

Supply Gas Requirements
•
Refer to AS/NZS 5601.1 for correct gas inlet piping
length from the gas meter to the heater.
•
Confirm correct supply pipe size and supply pressure
before proceeding with the installation.
• Check the gas meter to make sure it will supply
enough gas to the heater and any other appliances
using the same gas supply. If unsure, contact your
local gas utility to confirm.
• It is critical that the incoming gas supply pressure at
the heater is within the maximum and minimum
pressure requirements as outlined in
Table 2.
If the
range of acceptable supply pressure is not provided,
the gas supply system to the heater must be modified
to meet pressure requirements.
•
Consider pipe fittings when determining gas pipe
sizing. For every elbow used add 900 mm (3′) to
straight pipe length.
• Install a manual gas shutoff valve outside the heater
body for service and safety. Never install the shutoff
valve inside the body of the heater.
•
Where required by local code, install a sediment trap/
condensate fall and gas union in accordance with
Australia standard 5601. See
Figure 5
• Do not use a restrictive gas cock.
ATTENTION
Do not use fl exible appliance connectors on any gas connections
unless the connector is AGA approved for outdoor installation, and is
marked with the BTUH capacity (which must be equal to or greater
than the heater rated input) and the type of gas (Natural or LP). Also,
any fl exible connectors, such as CSST buried underground must be
certifi ed for underground installation and meet all applicable codes.
Please note, use of fl exible connector still requires the installation of
a sediment trap. See
Figure 5
.
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
.
