12. Electrical Supply:
Either 120 Volts AC or 240 Volts AC.
13. Modifi cation of Heater for High Altitude:
LXi heaters are normally shipped from the fac-
tory in the low altitude (sea level) operational
confi guration. Table 1 defi nes the altitude des-
ignations 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, CAN1-2.17 in Canada. When
an LXi heater is to be installed in a high altitude
application, the burner throat pressure will need
to be adjusted to achieve 1.0"WC. See Section
10.4.3 for instructions on how to do this.
