11. Modification of Heater for High Altitude:
The Jandy Lite 2 model LJ heater is normally
shipped from the factory in the low altitude (sea
level) operational configuration. When requested,
the heaters can be configured and shipped for
higher altitudes. For field conversions to change
altitude configurations, manifold kits for mid
altitudes and high altitudes are available from
your Jandy pool products dealer or by contacting
the Customer Service Department at (707) 776-
8200 extension 245. See Section 11, "Parts List",
of this manual for the correct kit number for the
manifold assembly needed for your altitude.
Table 1 defines the altitude designations as
described by the "Standard for Gas Fired Pool
Heaters", ANSI Z21.56 in the United States and
"Gas Fired Appliances For Use At High Alti-
tudes", CAN 1-2.17 in Canada.

2.1 Introduction

Install the Lite2 heaters, vent caps and draft
hoods in accordance with the procedures in this
manual, local codes and ordinances, and in accor-
dance with the latest edition of the appropriate na-
tional 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 Lite2 heater is shipped from the factory
with the top assembly in the low-profile configuration
for outdoor installation. The Lite2 heater is design
certified for indoor installation when equipped with a
draft hood, which must be installed without modifica-
tion.
The Lite2 heater is also certified for installation
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.
