- When commissioning the oil burner for the first ti-
me:
• check that the smoke spot number does not
exceed 0.5 (BACHARACH control),

Remark:
- The burners are preset in the factory for the ba-
lanced flue model FCX. Nevertheless the air and
oil inlet settings must be checked systematically
on commissioning and after all maintenance ope-
rations on the burner by testing the opaqueness
of the flue gasses and of the % CO2 - See the
burner technical instructions.
- For the installed flue model FCX boilers the air
setting must be readjusted to obtain the recom-
mended CO2/CO rate.
- The pressure of the burner oil pump shall be
checked or adjusted via the hole ( 37) after remo-
ving the plug.
