Introduction
The Jandy Pro Series JXi pool/spa heater is a blower
assisted, internal combustion chamber, residential
heater.
General
All gas fired appliances require correct installation to assure safe operation.
The requirements for this pool heater include the following:
Indoor vent adapter required for indoor installation.
Must be vented with Type B Double wall for Category 1 venting or stainless steel
vent pipe for Category 3.
Water piping can be Schedule 40 PVC.
Can be wired 120VAC or 240 VAC
The JXi CAN be installed on combustable surfaces.
Field Assembly
- Properly size gas pipe to supply gas from the meter to the heater.
- Gas shut-off valve (ball-cock) must be installed in-line outside of the heater jacket.
- Suitable gas union must be installed to connect gas line to heater outside of the heater jacket.
- Gas sediment trap (drip leg) in gas line between shut-off valve and heater.
- Supplied power 120VAC or 240VAC (as local code requires)

Installation Requirements (Field Assembly)
Supplied power 120VAC or 240VAC
Electrical wiring must be in accordance with the latest
edition of the National Electric Code® (NEC®), ANSI®/
National Fire Protection Association® (NFPA®) 70, or
in Canada, the Canadian Electrical Code (CSA® C22.1)
unless local code requirements indicate otherwise.
The heater comes factory-wired intended for use with 240
Vot, 60 Hz AC eld electrical supply. To use 120 Vot,
60 Hz AC requires changing the position of the voltage
selector board on the power distribution board. This must
be done by a certi ied electrician.

PLUMBING
Heater must be plumbed down steam of filter.
Heater must be installed so that when the filter pump is off so to is the heater.
All electrical equipment must be grounded and bonded.
The JXi heater is Versa Plumb ready.
The Versa Plumb System reduces hydraulic resistance by up to 50% versus other equipment sets in
its class.
The Versa Plumb System's increased hydraulic efficiency allows for up to a 1/2 HP smaller pump to
achieve the same level of flow, resulting in greater energy savings.
Faster installation with our pre-assembled plumbing kits, which enable quick and consistent equipment
plumbing design to reduce installation costs.
Innovatively designed system requires less plumbing pipe and fittings, while increasing hydraulic efficiency.

When the installation requires horizontal venting in excess
of what is allowed for Category I installations or calls
for horizontal discharge, the JXi may be installed with a
Category III venting system.
See Table 3 for recommended vent size and run lengths
without elbows. For each elbow installed, reduce the run
length by 12 feet (3.7m)

Connection to Jandy Control - RS 485
JXi CONNECTED TO AQUALINK RS AT RS 485 LINE
There are two ways of connecting a Jandy JXi heater to theAquaLink RS. One way is to connect at the Pool
and Common terminals of the Power Interface Board. This type of connection is shown on the next page. The
other way is to connect to the RS 485 line (red terminal bar) as shown here. When connected at the RS 485
line, the JXi andAquaLink RS become “smart” in that the control knows if the heater is malfunctioning. When
connecting to the RS 485 line, the AquaLink RS firmware must be Rev N or newer.
To establish communication between the LXi andAquaLink RS do either of the following:
After making connection turn power off then on to the AquaLink RS.
Hold the MENU button down for 5 seconds, then simply follow the screen prompts.

JXi HEATER CONNECTION AT “FIREMAN’S SWITCH”
At the JXi Power Interface Board connect one end of two wires to terminals POOL and COMMON (J6).
Connect the other end of these two wires to terminals 1 and 2 of theAquaLink RS Green terminal bar.
Set pool thermostat to maximum (104 F).
Set the JXi to recognize this type of connection by holding down MENU, POOL, and SPAbuttons
together for 7 to 10 seconds at the JXi’s User Interface. Set REMOTE to T-Stat. Press POOL button to
exit.

As with all pool heaters water velocity and flow through the heat exchanger are controlled by
an automatic bypass. The automatic bypass consists of a disk and spring and is located between
the Inlet/Outlet header.
A thermal regulator valve is also incorporated into this heater in the Inlet/Outlet header. Its
purpose is to hold water in the exchanger during initial heat up to reduce the amount of condensate
created at the heat exchanger.
