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, Zodiac Pool Systems, Inc.
strongly recommends installation of suitable Carbon
Monoxide detectors in the vicinity of this appliance
and in any adjacent occupied spaces.
AVERTISSEMENT
Une installation ou un entretien inadéquat peut
causer la nausée ou l’asphyxie en raison du mon-
oxyde de carbone présent dans les gaz de combus-
tion et même entraîner des blessures graves ou
la mort. Pour les installations intérieures, comme
mesure de sécurité additionnelle, Zodiac Pool
Systems, Inc. recommande fortement l’installation
de détecteurs de monoxyde de carbone près de
cet appareil ainsi que dans les espaces adjacents
occupés.
Install the Legacy heaters, vent caps and draft-
hoods in accordance with the procedures in this
manual, local codes and ordinances, and in accordance
with the latest edition 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
oor-
ing
3. Suf
fi
cient combustion and ventilation air
4.
Properly sized gas meter and piping
5.
Proper electrical wiring (if required)
6. Adequate

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 Legacy heater is shipped from the factory
with the top assembly in the low-pro
fi
le con
fi
guration
for outdoor installation. The Legacy heater is design
certi
fi
ed for indoor installation (U.S. only) when
equipped with a draft hood, which must be installed
without modi
fi
cation.
The Legacy heater is also certi
fi
ed for installa-
tion in an outdoor shelter in Canada when equipped
with a draft hood. An outdoor shelter is an enclosure
not normally occupied which does not communicate
directly with occupied areas.
Check the rating plate on the heater or the Parts
List (Section 11) of this manual for the correct Jandy
draft hood or vent cap part number. See instructions
supplied with the draft hood or vent cap for installation
and attachment. When the draft hood is used, locate
the heater so as to be in the same atmospheric pressure
zone as the combustion air inlet to the heater.
2.3 Location

fl
ooding or resulting damage.

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. Zodiac Pool Systems, Inc.
n’est
pas responsable des pertes d’eau, des inondations
