White smoke and/or sharp odors may be emitted from the vent dur-
ing 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.
8.2.2
If Ignition Is Unsuccessful
If ignition is unsuccessful, or the fl 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.

8.4
Normal Operation
During normal operation, the control system measures
the temperature of the water fl 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 airfl ow 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 fl ame
is sensed at the burner, operation continues until the
temperature of the water entering the heater reaches the
temperature control setting.
