MAIN FLAME FAILURE
Main Flame Failure is a fl ame failure that occurs while the
unit is trying to establish an adequate fl ame signal during the
Main Flame Trial for Ignition.
Solid state controllers indicate a Main Flame Failure by
showing as a fault code of either Fault 19 for Honeywell 7800
series controllers, Flame Failure MTFI on Fireye E110 series
controllers, or a Fault 09 for Fireye Nexus controls. For electro-
mechanical controls, you need to witness when the failure
occurs.
A Main Flame Failure indicates that either a strong enough
main fl ame was not generated or the means of sensing
the main fl ame strength has failed. During the main fl ame
proving period, the fl ame programmer must sense a strong
enough fl ame to hold the main valves open. If you are
experiencing Main Flame Failures, check the items indicated
in Table 10-N.
