DIAGNOSTICS AND FAULT LOCK-OUTS
FAULT LOCK-OUT
In the event that ignition is not detected within 90 seconds the heater will
switch off and retry ignition after 20 seconds. In the event that two
sequential failures are detected, the heater will flash the light on the control
button to indicate that service is required.
In the event that the flame extinguishes during operation the heater will
attempt to reignite itself three times before flashing the light on the control
button, indicating that maintenance is required.
In the event that the voltage drops below 10/19 Volts (for the 12 Volt/24
Volt system respectively) or goes above 15/32 Volts (for the 12 Volt/24 Volt
system respectively), the system will switch off for protection of the heater.

code, consisting of a series of short and long flashes of the light on the
control button. The coding of the error is as follows:
