OWNER'S OPERATING INSTRUCTIONS
FOR YOUR SAFETY - READ BEFORE OPERATING
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY
RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
SECTION 1 - START-UP PROCEDURES
Your pool/spa heater has been designed for years of safe and reliable pool/spa water heating. It is available with
millivolt or electronic ignition. ASME-certified units, typically used in commercial applications, are also available.
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 set-
tings for the pool or spa. The temperature range is factory set from 65°F (18°C) to 104°F (40°C). See figure
above for location of toggle switch to turn the heater On and Off. Section 4 of this manual contains more details
about the use of the controls in the Control Adjustments subsection (page 31).
