If your heater has been installed correctly, operating the
heater is an easy task. The upper front panel of the heater
contains the control center that allows you to turn the
heater On or O󰀨 and adjust the temperature settings for
the pool or spa. The temperature range is factory-set from
65°F (18°C) to 104°F (40°C). See Figure 71 for location of
toggle switch to turn the heater On and O󰀨.
See "Controls" section on page 27 for additional details
about the use of the controls in the Control Adjustments
subsection.

Feel the inlet and outlet pipes. Outlet pipe should be only
slightly warmer than the inlet. It should not be hot.

Water Pressure Switch
A water pressure switch is provided in the heater to shut o󰀨
the burners in the event that water supply is interrupted. It
is very important to verify that the switch electrically opens
and shuts o󰀨 the gas valve when water ow to the heater is
interrupted. Otherwise, rapid and severe damage will likely
occur to the heater.
The water pressure switch should be checked and adjusted
for proper operation by a qualied service person at the
time of installation and periodically checked thereafter.
Refer to "Water Pressure Switch Adjustment" on page
