Installation & Operation Manual
3.3.2
Direct Air Intake
In certain applications it may be necessary to supply
intake air directly to the heater. You will need to order
and install the direct air conversion R-Kit R0724600.
A total
equivalent
length of
15 m (50′)
of 75 mm
(3″) PVC
tubing can
be used to
bring the intake air
directly to the blower input.
Please be aware that each
elbow used will account for
3.6 m (12′) of length.
• For ease of access, remove the rear and top
panels.
a
Loosen the two screws securing the air orifice and
screen in place. Remove the air pressure switch and gas
valve hose from the air orifice.
b
Remove the air orifice, separate and dispose of
the orifice screen.
c
Align the
orifice adapter
with the
orifice tabs
and secure
with four
screws.
d
Dry fit the
75 mm (3″)
PVC tubing
into the orifice
adapter. Mark
screw hole
locations with
a pen.
Remove and
drill pilot
holes in the
PVC. Fit the PVC into the orifice adapter, align the holes and
secure with four screws
e
Reinstall the air orifice and air hoses.
f
Install the new rear panel over the PVC and secure with
four screws.
3.3.3
Exhaust Venting
When the JXi heater is installed indoors or in an outdoor
shelter the vent pipe sizing must be in accordance with
the specifications listed in
Table 1.

Vent Pipe sizing Requirements
WARNING
Vent pipe materials, sizing, and installation must be as required
by the National Fuel Gas Code NFPA 54/ANSI Z223.1 or Australia
Standard for Gas Pool Heaters, AS4560, AS/NZS 5601 Gas Instal-
lations as applicable by local code. Undersized pipe can result in
inadequate venting and oversize pipe can result in vent condensa-
tion. Improper selection of vent pipe material, incorrect sizing of the
pipe, and incorrect installation of vent piping can result in release of
combustion products to the indoors. This can cause serious injury or
death by Carbon Monoxide poisoning or asphyxiation.
WARNING
Improper installation or maintenance can cause nausea or asphyxia-
tion from carbon monoxide in fl ue gases which could result in severe
injury or death. For indoor installations, as an added measure of
safety, Zodiac strongly recommends installation of suitable
carbon monoxide detectors in the vicinity of this appliance and in
any adjacent occupied spaces.
Incorrect design and installation of heater vents and ducts can result
in personal injury, damage to property, or death. To avoid such
hazards, the heater must be installed only by a qualifi ed professional
service technician.
• STATIC PRESSURE - NEGATIVE:
Appliance
operates with a negative vent static pressure, a vent
gas temperature that avoids excessive condensate
production and will vent vertically terminating at the
roof. Termination must pass through a properly
installed and approved roof jack, a properly sized
storm collar and a listed vent cap. See
Figure 4.
• Do not
terminate heater vents near air conditioning or
air supply fans which could pick up exhaust flue
products, such as carbon monoxide and other
hazardous effluent, and return them inside the
building.
•
Vent pipe type and material must be carefully
selected and depends on the type of installation.
• Do not
locate the vent terminal where exhaust flue
products could strike against building materials and
cause degradation.
