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.
INTRODUCTION
Your pool/spa heater has been designed for years of
safe and reliable pool/spa water heating. It is available
with electronic ignition. This manual provides installa-
tion, 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 50°F (18°C) to 104°F (40°C). See fig-
ure 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 34).
SECTION 1 - START-UP PROCEDURE
1. Clean air louvers of dust, lint and debris.
2. Keep heater area clear and free from com-
bustibles, flammable liquids and chemicals.
3. Verify that the flow of combustion and ventilation
air is not obstructed.
4. Water must be flowing through the heater during
operation. Ensure that the system is filled with
water and the pump is operating. Double check
for any water leaks.
5. Purge air from the gas line. Insufficient purging
may keep the heater from lighting on the first try.
6. Double check gas connections, make sure no
leaks are present. Use soapy water to inspect.
7. Double check incoming electrical power, verify suf-
ficient output voltage to the heater.
8. The unit comes wired for 240V/1ph/60Hz power. If
the supply voltage is nominally 120V/1ph/60Hz,
switch the blower harness located inside the cabi-
net (see wiring diagram).
9. If installed indoors, make sure flue gases are vent-
ed properly, and that combustion and makeup air
openings are adequate.
10. Locate and turn the gas valve ON.
11. Locate the plugged bleedle valve off the right side
of the gas valve.
12. Remove the bleedle plug and connect a manome-
ter to the valve.
13. Locate and flip the display lid upwards.
14. Turn the heater on, by pressing the ON/OFF tog-

gle switch on the front display.
15. Set the mode to either SPA or POOL.
16. If the set point is higher than the current tempera-
ture, the heater will begin its startup sequence.
17. The ignition control will verify that the blower air
switch is open before starting the blower. Once
proven open, the blower will be powered to start
the ignition sequence.
matches the table below, Blower Suction
Pressure, for your model heater during the pre-
purge period.
18. Once the blower air switch proves, a 45 second
pre-purge period will begin to purge residual
gases from the combustion chamber.
