WARNING
When the heater is fired for the first time, the
combustion chamber refractory binder material is driven
out by the heat of the flame. White smoke and/or sharp
odors may be emitted from the vent during this period.
Do not inhale combustion product fumes at any time,
and especially when these fumes are being emitted. This
“burn-in” period will last only a few minutes.
9.4.1
If Ignition Is Unsuccessful
If ignition is unsuccessful, or the flame fails during
normal operation, the ignition control shuts off the
gas valve. The heater will then go through a post
purge process and attempt to establish stable
combustion two additional times. If ignition is
unsuccessful after three attempts, the system shuts
down and will automatically attempt to restart after
one hour.
• To reset the heater to provide three (3) attempts to
start:
• Turn OFF the control then turn it back ON.
• Access either the Pool or Spa mode.
9.5
To Turn Off Gas To The Heater
• Set temperature thermostat controls to their
lowest setting and turn off the controller. Make
sure the display shows GAS HEATER IS OFF.
• Turn off all electrical power to the heater at the
junction box.
• Remove the rear panel or top.
• Disconnect power connection to the gas valve by
unplugging the power supply plug from the gas
valve body.
• Shut off the external gas supply valve to the
heater.
• Replace the rear panel or top.

Normal Operation
During normal operation, the control system measures
the temperature of the water flowing through the
heater and will begin the start-up process if the
temperature is below the set point. If the blower
pressure switch senses adequate airflow when the
blower starts, the ignition sequence begins. Following
a pre purge, the igniter is energized, then the gas valve
opens. As long as a flame is sensed at the burner,
operation continues until the temperature of the
water entering the heater reaches the temperature
control setting.

Operating The Controller
Unless the heater is connected to a remote controller,
all operations are set up and programmed through
the control panel on the top of the heater. See
