SECTION 2.
Installation Instructions
2.1 Introduction
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, Waterpik
Technologies 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
monoxyde de carbone présent dans les gaz de
combustion et même entraîner des blessures
graves ou la mort. Pour les installations
intérieures, comme mesure de sécurité
additionnelle, Waterpik Techonologies
recommande fortement l’installation de
détecteurs de monoxyde de carbone près de
cet appareil ainsi que dans les espaces
adjacents occupés.
Install the LX and LT Low NOx heaters and
vent collars 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-fired 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
flooring
3.
Sufficient combustion and ventilation air
4.
Properly sized gas meter and piping
5.
Proper electrical wiring (if required)
6.
Adequate water flow
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 LX and LT Low NOx heaters can be
installed in a variety of ways, some of them requiring
preparation or assembly in the field. The heater is
shipped from the factory with an exhaust vent config-
ured for an outdoor installation. The LX and LT Low
NOx heaters are also design certified for "Indoor"
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) of this manual for the correct Jandy
vent collar part number. For specific installation
information 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
final location. See Section 5.4 "Reversible Water
Connections" of this manual for instructions.
2.3 Location Requirements
2.3.1 Introduction
CAUTION
When pool equipment is located below the pool
surface, a leak from any component can cause
large scale water loss or flooding. Waterpik
Technologies cannot be responsible for such
water loss or flooding 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. Waterpik
Technologiesn’est pas responsable des pertes
d’eau, des inondations ou des avaries causées
par une installation ou un entretien inadéquat.
The LX and LT Low NOx heaters may be
installed indoors or outdoors as outlined in later sec-
tions. 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 flow around the heater.
All criteria given in the following sections reflect
minimum clearances as stated in the national stan-
dards. However, each installation must also be evalu-
ated, 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
