Section 2. Installation Instructions
2.1 Introduction
WARNING
Improper installation or maintenance can cause
nausea or asphyxiation from carbon monoxide in
fl ue gases which could result in severe injury, or
death. For indoor installations, as an additional
measure of safety, Jandy Pool Products, Inc.
strongly recommends installation of suitable Car-
bon Monoxide detectors in the vicinity of this appli-
ance and in any adjacent occupied spaces.
AVERTISSEMENT
Une installation ou un entretien inadéquat peut
causer la nausée ou l’asphyxie en raison du
monoxyde de carbone présent dans les gaz de
combustion et même entraîner des blessures
graves ou la mort. Pour les installations intéri-
eures, comme mesure de sécurité additionnelle,
Jandy Pool Products, Inc. recommande forte-
ment l’installation de détecteurs de monoxyde de
carbone près de cet appareil ainsi que dans les
espaces adjacents occupés.
Install the LXi heater and vent collar in accor-
dance with the procedures in this manual, local codes
and ordinances, and in accordance with the latest edi-
tion of the appropriate national code. See Section 1.4,
Codes and Standards.
All gas-fi red products require correct installation
to assure safe operation. The requirements for pool
heaters include the following:
1. Field assembly (if required)
2. Appropriate site location (clearances) and fl ooring
3. Suffi cient combustion and ventilation air
4. Properly sized gas meter and piping
5. Proper electrical wiring (if required)
6. Adequate water fl ow
This manual provides the information needed to
meet these requirements. Review all application and
installation procedures completely before continuing
the installation.
2.2 Field Assembly
The LXi heater can be installed in a variety of
ways, some of them requiring preparation or assembly
in the fi eld. The heater is shipped from the factory
with an exhaust vent confi gured for an outdoor instal-
lation. The LXi heater is also design certifi ed for “In-
door” installations in the United States and “Outdoor
Shelter” installations in Canada when equipped with a
vent collar and the appropriately sized exhaust vent.
Check the rating plate on the heater or the Parts
List (Section 11.2) in this manual for the correct Jandy
vent collar part number. For specifi c installation infor-
mation see Section 2.3.5, Indoor and Outdoor Shelter
Installations.
Water connections are provided on the right side
of the heater but can be changed to the left side by
reversal of the heat exchanger. It is best to handle these
preparations before the heater is installed in its fi nal lo-
cation. See Section 5.4, Reversible Water Connections,
in this manual for instructions.
2.3 Location Requirements
2.3.1 Introduction
CAUTION
When pool equipment is located below the pool sur-
face, a leak from any component can cause large
scale water loss or fl ooding. Jandy Pool Products,
Inc., cannot be responsible for such water loss or
fl ooding or resulting damage.
ATTENTION
Lorsque l’équipement d’une piscine est situé sous
la surface de l’eau, une fuite provenant de n’importe
quel élément peut causer une perte d’eau importante
ou une inondation. Jandy Pool Products, Inc. n’est
pas responsable des pertes d’eau, des inondations
ou des avaries causées par une installation ou un
entretien inadéquat.
The LXi heater may be installed indoors or
outdoors, as outlined in later sections. Location of
the heater below or above the pool water level affects
operation of its water pressure switch. See sections on
water piping and heater start-up for more information
about this.
Avoid placing the heater in locations where it can
cause damage by water or condensate leakage. If this
is not possible, provide a suitable drain pan to catch
and divert any leakage. The pan must not restrict the
air fl ow around the heater.
All criteria given in the following sections refl ect
minimum clearances as stated in the national stan-
dards. However, each installation must also be evaluat-
ed, taking into account the prevailing local conditions
such as wind speed and direction, proximity and height
of walls that may block ventilation, and proximity to
public access areas.
2.3.2 Clearances
The heater must be placed to provide clearances
on all sides for maintenance and inspection. There
must also be minimum distances maintained from
combustible surfaces. See Table 2.
At least 18" (457mm) access must be available in
front of the heater for burner removal and access to
the igniter.
If the heater is to be installed in a garage, or
