Installation & Operation Manual
Section 4. Gas Connections
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 greater than or equal to 1/2 psi (3.5kPa).
CAUTION
Permanent damage to the gas valve will occur if the installation
procedures are not followed correctly.
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. CONVERTING THIS HEATER FOR
USE WITH ANY OTHER FUEL TYPE IS NOT RECOMMENDED
BUT, WHEN NECESSARY, SHOULD ONLY BE PERFORMED BY A
LICENSED AND QUALIFIED PROFESSIONAL, AND ONLY AFTER
CONTACTING ZODIAC POOL SYSTEMS FOR THE PROPER
INSTRUCTIONS AND CONVERSION KIT.
All questions should be directed to the Zodiac customer service
center at 1-800-822-7933

Numbers are for natural gas (0.60 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.

Check supply pressure and local code requirements before proceeding with installation.

It is critical that the incoming gas supply pressure at the heater is within the maximum and minimum pressure requirements. If the range

•
Refer to
Table 2
for correct gas inlet piping length
from the gas meter to the heater.
• 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 confi rm.
• 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.
• Install a sediment trap and union ahead of the gas
controls and outside the heater body. See
Figure 6.
• Do not use a restrictive gas cock.

unless the connector is CSA 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,

.
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.
