Modification of Heater for High Altitude:
The Lite 2 model LG 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 Altitudes", CAN 1-
2.17 in Canada.
