Jandy® Pro Series, Hi-E2® and Hi-E2R Gas-Fired Heater | Installation & Operation Manual
Section 1. General Information
1.1 Introduction
This manual contains information for the proper
installation and operation of the Hi-E
EHE pool/spa heater. Certain sections are specic to
United States or Canadian installations, and are labeled
United States or Canada. Procedures in this manual must
be followed exactly. To obtain a copy of this manual
contact Zodiac Pool Systems, Inc. ("Zodiac
address information. See back cover.
1.2 Description
The Hi-E2 Low NOx heater is a very efcient gas-red
pool and spa heater. Its combustion system includes a
heat exchanger which extracts 95% of the energy in the
gas fuel. It has no standing pilot burner. It exceeds the
requirements of energy conservation regulations such as
those in California, Hawaii, New York, Oregon and other
states which require that a pool heater have intermittent
ignition.
The heater is designed to operate in conventional
swimming pool and spa equipment arrangements. It
requires 115V 60 Hz electrical power. It has the versatile
dual-thermostat control system for pool/spa combinations.
The Hi-E2 is certied by CSA International to comply with
latest editions of applicable standards. In the United States,
the applicable standard is ANSI Standard Z21.56 for gasred pool heaters. In Canada, it is Standard CSA 4.7.
The Hi-E
to heat fresh water swimming pools and spas, and with
proper installation and care, it will provide years of
reliable service. Do not use it to maintain pool or spa
water temperature below 70°F. Do not use it as a heating
boiler or general service water heater or to heat true salt
water systems where salinity is in the 35,000 ppm range.
For special applications, consult your Jandy Pro Series
dealer.

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.
Section 2. Installation Instructions
2.1 General Requirements
All gas-red products require correct installation to assure
safe and satisfactory operation. The requirements for pool
heaters include the following:
1. Appropriate site location and clearances.
2. Sufcient supply of clean air for combustion and
ventilation.
3. Proper venting of products of combustion.
4. Properly sized gas pipe.
5. Properly sized gas meter.
6. Adequate water ow.
7. Provision for disposal of combustion condensate
water.
In the United States, installation must be in accordance
with local codes and the most recent edition of the
National Fuel Gas Code, ANSI Z223.1/NFPA-54. The
Code can be obtained from:
National Fire Protection Association
1 Batterymarch Park
Quincy, MA 02169
www.nfpa.org
In Canada, install the heater in accordance with local
codes and the most recent edition of the Natural Gas and
Propane Installation Code, CAN/CSA B149.1.
1.3 Warranty
The Hi-E2 is sold with a limited factory warranty. A copy
of the warranty is included in a plastic bag inside the
heater. The warranty does not cover damage caused by
improper installation, operation, or eld modication; or
damage to the heat exchanger caused by corrosive water.
See Section 3.4 for guidelines on pool water chemistry.
Special Precautions
Liqueed petroleum (LP) gas is heavier than air.
Therefore, a pool heater using LP gas is subject to special
installation rules. Consult local codes and re protection
authorities about specic installation restrictions.
Fuel gas and its combustion products are known to cause
cancer or harm the reproductive process. Follow these
installation instructions and applicable codes exactly to

Jandy® Pro Series, Hi-E2® and Hi-E2R Gas-Fired Heater | Installation & Operation Manual
WARNING
To Reduce the Risk of Fire, install pool equipment in an
area where leaves or other debris will not collect on or
around the equipment. Keep surrounding area clear of
all debris such as paper, leaves, pine-needles and other
combustible materials.
ENGLISH
Page 5
When pool equipment is located below the pool surface,
a leak from any component can cause large scale water
loss or ooding. Zodiac Pool Systems, Inc. cannot be
responsible for such water loss or ooding or resulting
damage. Location of the heater below or above the pool
deck affects operation of its water pressure switch. See
sections on water piping and heater start-up for more
information about this.
2.2 Heater Assembly and Preparation
The Hi-E2 can be installed in a variety of ways, some of them
requiring preparation or assembly in the eld. In all cases,
condensate tubing and ttings, which are provided with the
heater, must be connected and routed. Water connections are
provided on the right side of the heater but can be changed to
the left side by reversal of the water headers.
It is best to handle these preparations before the heater
is in its nal location. Instructions are provided in
subsequent sections of this document.
Installation at High Elevation
The Hi-E
2 has a venturi-type combustion system which
does not require modication for operation at high
elevation. In this type of system, air and fuel gas density
changes are automatically compensated for, assuring
proper air/fuel mixture. Heating capacity is reduced about
3 percent per 1000 feet (305 meters) above sea level. In
general, efciency at high elevation is equal to or better
than at sea level.
2.3 Heater Location
The Hi-E2 may be installed indoors or outdoors as outlined
in later sections. When installed indoors, combustion
air will often be piped to the heater and this requirement
may affect the choice of location, see later section on air
for combustion and ventilation. Both indoor and outdoor
installations require provision of means for disposal of
combustion condensate per section 2.8.
Install the heater at least 5 feet (1.52 meters) from the
inside wall of the pool or spa unless the heater is separated
from the pool or spa by a ve-foot (1.52 meter) high solid
fence, wall or other permanent barrier.
Equipment must be installed on a rm, solid, nonabsorbent level surface; and per the requirements of
local codes and Authority Having Jurisdiction (AHJ).
Equipment can weigh up to 300 lbs. Use suitably rated
mounting surface materials to avoid risk of settlement,
and never use sand to level the equipment as the sand
will wash away. Check local building codes for additional
requirements.
Locate the heater in an area where water leakage will
not result in damage to the area around the appliance or
to a structure. If forced to locate the heater where water
leakage may cause damage, provide a suitable pan with
drain under the heater. This pan must not restrict air ow
or heater functions.
In selection of a location, disposal of combustion
condensate must also be considered. The heater can
produce three gallons of condensate water per hour
under some operating conditions. Means to drain this
condensate must be available or special provisions, such
as a condensate pump must be provided. See later section
on condensate disposal.
2.4 Installation Clearances
Clearances between the heater and combustible material
must be per Table 1.
Table 1. Installation Clearance Requirements.
Surface/Component Minimum Clearance
Inches (mm)
Rear & Blank Side 2 (55)
Piping Side 12 (305)
Front 18 (455)*
Top - Indoors 6 (150)
Top - Outdoors Open (See Note)
Flooring Combustible
Vent 0
* For Canada 24 inches (610 mm) clearance
NOTE See Section 2.5 for outdoor installation requirements.
These clearances are the minimum acceptable. Whenever
possible, larger clearances should be provided to assure
adequate room for service operations. Note that gas piping
must be provided through the left side of the unit and
that the combustion air duct, when provided, also enters
through the left side. See later section on combustion air,
and also the section on water piping.
Do not install the heater on carpeting or similar material.
2.5 Outdoor Installation
CAUTION
When pool equipment is located below the pool
surface, a leak from any component can cause large
scale water loss or flooding. Zodiac Pool Systems, Inc.
cannot be responsible for such water loss or flooding
or resulting damage.
Locate the heater in an open, unroofed area and maintain
the clearances shown in Table 1. Do not locate the heater
below or adjacent to any doors, windows, louvers or
grates, etc., which connect in any way with an inhabited
area of a building, even through another building such as

a garage or utility room, see Figure 1. Do not locate the
heater below an outdoor deck, unless treated as an indoor
installation with adequate clearances and proper venting
to a location away from the deck.
If the heater is installed close to a structure, protect it from
rain water runoff by means of gutters, roof water diverters
or similar measures. Do not locate the heater close to
irrigation sprinklers. Water from sprinklers may damage
controls and electronic components.
Because the Hi-E
2 is very efcient, combustion system
exhaust gases are moist. Do not locate the heater such
that this exhaust will impinge on structures or vegetation
which may be damaged by combustion condensate.
WARNING
United States
Do not install the heater with the top of the vent
assembly within 4 feet (1.22 m) horizontally, 4 feet
(1.22 m) below or less than 1 ft (300 mm) above of any
opening into a building.
Canada
Do not install the heater with the top of the vent
assembly within 10 feet (3.05 m) of any opening into a
building.
In Florida it is required that the heater be securely
fastened to the equipment pad. Use a size 1/4” x 2-1/4”
long galvanized or plated concrete screws and washers
at each of the four (4) tabs located at the base of the
heater. Mounting the appliance in this manner meets the
applicable requirements of the Florida Building Code.
Mounting screws are not provided with this heater. After
placing the heater on the equipment pad, drill a hole in
the concrete at each of the four (4) tabs on the feet of the
heater. (The correct size drill bit is usually provided with
the concrete screws when purchased). Place a screw in
2.6 Outdoor Shelter Installation (Canada)
An outdoor shelter is an unoccupied enclosure which
does not communicate directly with occupied areas.
The Hi-E
2 may be installed in such a shelter only when
the installation is in accordance with local codes and
the most recent edition of the Natural Gas and Propane
Installation Code (CAN/CSA B-149.1). These codes and
®
standards and Zodiac
require that the heater be properly
vented as outlined in this manual. Other requirements also
apply, such as provision of ample uncontaminated air for
combustion and ventilation.
2.7 Indoor Installation
The Hi-E2 can be located indoors when provided with
“one-pipe” or “two-pipe” systems for combustion air
and combustion product venting. A one-pipe installation
has only a vent pipe, and air for combustion must be
provided to the room the heater is located in. A two-pipe
system (sometimes referred to as “direct vent” or “sealed
combustion”) has a vent pipe plus a pipe bringing air
directly to the heater's combustion system.
Section 2.7.2 species requirements for provision of
combustion and ventilation air for one-pipe installations.
Section 2.7.3 covers two-pipe installation.
An important consideration in selecting one (1) or two
(2) pipe installation is the quality of the combustion
air. Indoor air is sometimes contaminated with various
household or pool sanitation chemicals which can cause
corrosion in the heater combustion system. Unless the
indoor air is known to be free of these materials, two (2)
pipe installation is strongly recommended.
2.7.1 Preparation of Heater For Indoor Installation
If the Hi-E2 is to be installed indoors, its exhaust discharge
grille must be converted to an exhaust pipe conguration.
Jandy® Pro Series, Hi-E2® and Hi-E2R Gas-Fired Heater | Installation & Operation Manual
ENGLISH
Page 7
The necessary vent collar, gasket and screws are shipped
packaged within the heater. The conversion can be done
quite simply as follows. See Figures 3 and 4:
1. Remove the vent exhaust grille by removing the
four (4) screws which retain it. The grille, its
gasket, and the screws may be discarded.
2. Place the vent collar gasket on the top of the
heater aligning its center hole and screw holes
with those in the top of the heater.
3. Place the vent collar over the gasket and fasten
it in place with the screws and lockwashers
provided. Be sure that all components are
properly aligned. Screws must be tightened
enough to assure a sealed joint without deforming
the vent collar.
2.7.2 Combustion Air Requirements for One-Pipe
Installation
One-pipe indoor installations must have specic
provisions for supply of combustion and ventilation air
to the room in which the heater is located. Two (2) air
openings must be provided — one (1) near the ceiling
and one (1) near the oor. When air is provided directly
through an outside wall, each opening must have at least
1 square inch (6.5 square cm) of area per 4000 BTU/h of
heater input. When air is provided indirectly through ducts
from the outside, the openings and passages must have
at least 1 square inch of area per 2000 BTU/h of heater
input. These requirements are interpreted in Table 2.

®
Zodiac
does not recommend installations with only
“inltration” as the means for provision of combustion air.
Figure 3. Removal of outdoor exhaust grille.
See Section 2.7.3.3 for vent pipe sizing.
WARNING
Do not store any chemicals, cleaners, or other corrosive
material near combustion air openings or in the
room. Avoid locating appliance vents in the vicinity of
combustion air openings. Failure to prevent corrosive
materials from mixing with combustion air can result in
reduced heater life and unsafe heater operation.
2.7.3 Two-Pipe Installation (Direct Vent)
This section species installation requirements
for combustion air and vent piping for “two pipe”
installations. A two-pipe system provides isolation of the
2 combustion system from the space in which the
Hi-E
heater is installed. It has not only a vent pipe, but also
a combustion air pipe to provide air directly from the
outdoors. Research studies have shown that contaminants
which may corrode internal heater parts are typically at
much lower levels in outdoor air than in air from indoors.
2.7.3.1 Connection of Combustion Air Pipe
A collar for combustion air pipe connection is provided in
the heater at the inlet of the lter box. As shown in Figure
5, the combustion air pipe is routed through the side of the
heater to the lter box connection. Remove the cover plate
from the left side panel to provide access for the air pipe.

WARNING
To avoid risk of property damage, serious injury, or
death, use ONLY piping materials from the list below
which are certified or listed for the application per
the requirements of UL 1738 and/or ULC S636, by a
Nationally Recognized Testing Laboratory (NRTL).
Vent piping must be corrosion resistant because
combustion condensate is usually present on its internal
surfaces. The materials listed in Table 3. are acceptable
for vent piping:

2.7.3.3 Size and Length of Combustion
Air and Vent Piping
Piping for combustion air and venting must be large
enough to avoid restriction of the heater combustion
system. Pipe diameter, number of elbows and length of
pipe determine how much it restricts ow to or from the
heater. Table 3 species the allowable length of piping for
various situations.

be increased. 140 feet of 5” piping would be sufcient
to complete the run.
2.7.3.4 Combustion Air and Vent Pipe
Installation
The Hi-E2 must be vented to the outdoors. Refer to Figure 7.
It must not be vented in common with any other appliance,
even if that appliance is of the condensing type. Common
venting can result in severe corrosion of the Hi-E
2 or of the
other appliances or their venting, or escape of combustion
product gases through such appliances or vents. Do not vent

2 to a replace chimney or building chase.
Combustion air ducting, when provided, must not be
shared with any other appliance or with another Hi-E
2.
Doing so may result in ow of air through the other
appliances instead of directly from the outdoors.
The combustion air intake and vent outlet must be located
exterior to the building and in the same pressure zone - i.e.
both through the roof or both through a side wall. The vent
terminal must be located in accordance with local codes, as
applicable, and in accordance with the following:
1. Locate the vent terminal so that it will not be
damaged by pedestrians and other trafc, and so
that the discharge is not offensive. The National
Fuel Gas Code requires a through-wall vent
terminal be at least 7 feet (2.13 m) above grade if

located at a public walkway.
2. Locate the vent terminal so the vent exhaust does
not settle on building surfaces and other nearby
objects. Vent products may corrode such surfaces
or objects.
3.
Locate the vent terminal at a sufcient horizontal
distance from any gas or electric metering,
regulating or relief equipment. In the United States,
this distance must be at least 4 feet (1.22 m). In
Canada, it must be at least 10 feet (3.05 m).
4. Locate the vent terminal at a sufcient horizontal
distance from any building opening. Take special
care to assure that combustion products do
not enter a building through windows, doors,
ventilation inlets, etc. In the United States, this
distance must be at least 4 feet (1.21 m). In
Canada, it must be at least 10 feet (3.04 m).

to size as necessary.
As shown in Figures 8 and 9, the combustion air intake
and the vent outlet must be installed no closer together
than 18" (45.7cm) and no farther apart than 60" (1.5m).
The combustion air inlet opening must face downward
to prevent entry of rain or snow. The vent outlet must
discharge away from the combustion air inlet - normally
in a horizontal direction when on a wall and vertically
upward when on a roof. Both should terminate at least
12" (30.5cm) above the snow accumulation level. In
locations with freezing climate, extension of the vent pipe
outside of the building should be minimized. The insect
screens provided with the heater must be installed at the
combustion air and vent pipe openings as shown in Figure
10. Insect screens are sized to t the inside of a 5" PVC
pipe tting. Trim them as necessary for smaller pipe sizes.
Connect the vent pipe to the heater vent collar with an air-
tight corrosion-resistant clamp. The connection must not
allow leakage of combustion products into the space but
should be removable for service. See Figure 7.
The room a Hi-E
2 is installed in must be provided with
adequate ventilation. Like other gas-red appliances, the
2 releases heat to its environment, and a room with no
Hi-E
ventilation may become too warm.
In one-pipe installations, the normal (code-required)
provisions for combustion air also assure reasonable
ventilation of the room. If a two-pipe system is installed,
ventilation must be provided by other means, such as
through grilles or openings or with a small fan.
2.7.3.6 Inspection and Replacement of
Existing Vent System with New
Components
If the Hi-E
2 is being installed to replace an existing pool
heater, it is recommended that a new appropriate venting
system be installed with the new heater. However, if
an existing venting system must be used, be sure to
carefully inspect the venting system to ensure that it is
in good condition and continues to be appropriate for the
2 heater. Replace any parts that are not in good and
Hi-E
serviceable condition with new parts before completing
the pool heater installation.
2.8 Condensate Disposal
In a high-efciency combustion process, combustion
product gases are cooled so much that liquid water is
condensed. Flow of this “condensate” can be quite high.
When pool water is very cold, as much as 2 or 3 gallons
Connect the combustion air pipe to collar of the air lter
box. For this combustion air pipe only, sheet metal pipe is
most convenient and can be screwed directly to the collar.
Seal the joint with silicone sealer or similar mastic material.
Install vent piping with a continuous rise of at least 1/4"
per foot (20 mm per meter) away from the heater. This will
assure that any condensate forming in the vent pipe will
ow back to the heater where it can be disposed of properly.
Support vent piping with suitable hangers so its weight
does not bear on the heater or building penetration and
so that piping joints are not strained. Support horizontal
runs at intervals no greater than 6 feet (1.82 meters), and
closer if necessary to avoid sagging. Sagging can trap
condensate water and block the vent.
Both combustion air and vent piping joints must be sealed.
Metal combustion air pipe joints should be fastened with
screws and sealed with permanent sealer or tape. Plastic
vent pipe joints must be made with solvent cement listed

of condensate can be produced in an hour. Condensate is
mildly acidic. Before treatment, its “pH” is typically in the
3.5 to 6.0 range.
Handling and disposal of condensate is not complicated,
but it must be done correctly to prevent problems or
complaints. A trap/neutralizer assembly is provided with
the heater to simplify installation. This assembly is easily
installed in the base of the heater. Figure 11 illustrates its
installation and the routing of drain tubes.
To install the condensate assembly, fi rst install the
short length of 5/8" I.D. tubing (Collector Drain) on
the barbed fi tting on the bottom of the condensate
collector. Then drop the condensate tray into the opening
in the base pan of the heater, bending the 5/8" tubing as
necessary to get the tube into the tray. Readjust the 5/8"
tubing so that its lower end is 1/4" - 3/8" above the bottom
of the tray. The tray can be positioned with the outlet tting
to the right, as shown in Figure 11, or with the tting to the
left, depending on the direction required for condensate
disposal. Connect the piece of 1/2" I.D. tubing to this
outlet tting and route it out of the heater through the hole
in the side of the base panel. This tube carries condensate
to the drain. If this disposal tube is routed to the left,
remove the plug button from the hole on the left side of the
base panel and push it into the hole on the right side.
Connect the remaining short piece of 3/8" I.D. tubing to
the barbed tee tting in the tubing immediately in front of
the blower. Position this tubing so that its bottom end is
1/4"-3/8" above the bottom of the condensate tray. This
tube provides drainage for the vent duct and blower.
A package of limestone gravel neutralizer is provided with
the condensate assembly. Remove the neutralizer from the
packing and spread evenly throughout the tray and around
the properly placed tubes. Be sure that a limestone pebble
does not plug any of the tubes.
IMPORTANT After placing the limestone neutralizer in
the tray add water until the water level is at the same
height as the overflow, see figure 12. Place the cover
on the tray when this is done.
It is important that there be no sagging sections of tubing
to trap water. Drainage to the trap and out of the trap
to the drain must be assured by continuous downward
routing of these tubes. It may be necessary to elevate
the heater to provide downward routing. The outlet of
the disposal tube must be open to the air. PVC pipe is
recommended for long drain tubes.

12 illustrates the water seal. Note that water is “pulled”
up toward the condensate collector pan and is pushed
down slightly by the vent/blower drain. If there is no water
seal, air rushes into the collector drain, preventing normal
drainage of condensate water, until vent drainage provides
the seal. See Section 2.12, Start-Up and Adjustment.
The installer must be sure to take whatever measures
are necessary to prevent property damage by condensate
over ow. If the heater location is such that this water
can directly or indirectly damage a building, furnishings
or other property, an over ow pan or other appropriate
preventative measure should be provided.
2.9 Gas Supply and Piping
Before installing gas piping, check the rating plate on the
heater to be sure that the heater is for use with the correct
(available) gas. Make sure that gas supply pressure is
adequate per the requirements in Table 4.
If a gravity drain is not available, a condensate pump
must be provided in the eld. Suitable condensate pumps
are available commercially at air conditioning equipment
distributors.
Incorrect installation of the condensate assembly or
tubing can result in over ow or waterlogging of the vent.
In normal operation, water accumulates in the tray at the
level of the outlet tting, and this provides a “water seal”
which accommodates combustion system pressures. Figure

Code, ANSI Z223.1/NFPA-54.
Do not use exible appliance connectors on any gas
connections 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, any
exible connectors, such as CSST buried underground
must be certied for underground installation and meet all
applicable codes. Please note, use of exible connector still
requires the installation of a sediment trap per NFPA 54.

Support gas piping properly so its weight does not bear on
the heater. Install a drip leg, a non-restrictive shutoff valve
and a union on the gas supply line outside of the heater.
See Figure 13.
Before operating the heater, test the gas supply system,
including all connections, for leaks using a soap solution.
Do not use a ame or any ignition source for leak
detection. Disconnect the heater and its individual gas
shutoff valve during pressure testing if the test pressure is
higher than 1/2 psig (3.34 kPa). If the pressure is 1/2 psig
(3.45 kPa) or lower, close the manual valve on the heater
gas control during testing.
When the heater is started, check the supply pressure
to verify that it is adequate during heater operation.
Undersize piping, a restrictive tting or an undersize gas
meter can cause low operating pressure.
High Elevation
To assure good combustion and general operation, gas
appliances may require manual de-rating when installed
at high elevation. This is not necessary with the Hi-E
2
because it has a special venturi-type combustion system
which self-compensates for changes in barometric
pressure. Air ow through the venturi pulls the correct
ow of gas into the burner regardless of air density.
Good quality combustion and high efciency are assured
without special adjustment or changes to the heater.

2.9.1 Special Precautions for LP Gas
LP Gas is heavier than air and can therefore more readily
collect or “pool” in enclosed areas if provision for proper
ventilation is not made. Installation of pool heaters in
enclosed areas such as pits is not recommended. However,
if such an installation is required be sure to pay special
attention to proper ventilation requirements for LP gas.
Locate heaters a safe distance from LP gas cylinders and
lling equipment. Consult the National Fuel Gas Code
(NFPA 54 / ANSI Z223.1, latest edition), the Natural
Gas and Propane Installation Code in Canada (CAN/
CSA B149.1, latest edition), and any other local codes
and re protection authorities about specic installation
restrictions in your area.
