flammable liquids and chemicals. Do not obstruct the flow
of combustion and ventilation air.
Water
Water must be flowing through the heater during operation.
Ensure that the system is filled with water and that the

contains the control center that allows you to turn the
heater On or Off 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

Water Pressure Switch
A water pressure switch is provided in the heater to shut off
the burners in the event that water supply is interrupted. It
is very important to verify that the switch electrically opens
and shuts off the gas valve when water flow 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 qualified service person at the
time of installation and periodically checked thereafter.
