Keep heater area clear and free from combustibles,
flammable liquids and chemicals. Do not obstruct the flow
of combustion and ventilation air.

Start-Up Procedures

Your pool and spa heater has been designed for years of
safe and reliable pool/spa water heating. It is available with
electronic ignition only. This manual provides installation,
operation, maintenance, and service information for these
heaters.

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 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 Figure 71 for location of
toggle switch to turn the heater On and Off.
See "Controls" section on page 27 for additional details
about the use of the controls in the Control Adjustments
subsection.
After Start-Up
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 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.
Refer to "Water Pressure Switch Adjustment" on page
38.
