9.2.2 If Ignition Is Unsuccessful
If ignition is unsuccessful, or the ame 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.
9.3 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.
• Toggle gas control switch to OFF.
• Shut off the external gas supply valve to the heater.
• Replace the rear panel or top.
9.4 Normal Operation
During normal operation, the control system measures
the temperature of the water owing 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 airow 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 ame
is sensed at the burner, operation continues until the
temperature of the water entering the heater reaches the
temperature control setting.
