(item no. 1),
• For the FCX + domestic hot water production
tank models or other type:
. press the Summer/Winter switch (item
no.

. set the tank domestic hot water thermostat
to the required temperature,
. position the boiler temperature thermostat
(item no. 3) to the minimum,
. set the mixer valve (fig. 2, item no. 5) to po-
sition "0".
In the summer it is advisable to operate
the heating pump for several minutes to
avoid any risks of fouling (see §

(When the boiler is equipped with an
electronic regulator, this function is
performed automatically).

(item no. 3) to maximum.
6.3 - Commissioning the oil burner
- When commissioning the oil burner for the first ti-
me:
• check that the smoke spot number does not
exceed 0.5 (BACHARACH control),
• check the CO2 rate - 11.5 to 12.5 %, CO < 100
ppm (watch out for secondary air inlets),
• check the temperature of the combustion pro-
ducts (under 120 °C).
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
