F09 Fault Code: No Flame On

Postby HTP » Wed May 30, 2012 1:16 pm

The boiler tried to ignite four times during one heat call and failed. The red FAULT light and LOCKOUT will flash on the display. This code indicates a seri-ous safety issue. The boiler will not restart until the cause of ignition failure is repaired by a technician and he pushes the RESET button on the display. During this lockout fault, the pump will remain on as indicated on the second line of the display.
