FAULT
The burner does not start
The burner starts and then goes into
lock-out
After pre-purge and the safety time, the
burner goes to lock-out and the flame
does not appear
The flame ignites normally but the burner
locks out when the safety time has
elapsed
Firing with pulsations or flame detach-
ment, delayed firing
The burner does not pass to 2nd stage
Fuel passes to 2nd stage but air remains
in 1st
Burner stops at transition between 1st
and 2nd stage. Burner repeats starting
cycle.
Uneven fuel supply
Internally rusted pump
Noisy pump, unstable pressure
Pump unprimes after prolonged pause
Pump leaks light oil
Smoke in flame - dark Bacharach
- yellow Bacharach
