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 51
for location of
toggle switch to turn the heater On and Off.
See
Section 7
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.

WARNING:
Should overheating occur or the gas
supply fail to shut off, turn off the manual gas control to
the appliance.
Visual inspection
With the heater on, remove the door and make a visual
check of the pilot and burner. The flame should be blue
with a well-defined pattern.
A yellow or “floating” flame indicates restricted air openings
or incorrect orifice size. Should this occur, shut the heater
off and contact your installer or gas supplier.
