4.2.3 Flame Loss During Run (On Units Less Than 2.5 Million BTUs)
If a Flame Loss During Run fault is encountered, the C-More will attempt one re-ignition
sequence. If two successive Flame Loss During Run faults are encountered within a 15 minute
span, the C-More will go into a Hard Fault mode requiring operator intervention.
The Ignition Retry Sequence for Flame Loss During Run consists of the following actions and
displays:
1. WAIT FAULT PURGE – A 15 second PURGE to remove any GAS from the system.
2. WAIT RETRY PAUSE - A 30 second pause before another trial is attempted.
3. WAIT IGNITION RETRY – This is the standard Ignition Sequence
Any loss of flame while running will be recorded in the C-More Fault Log, even if it is followed by
a successful Ignition Retry.
