2 - FILLING THE SYSTEM WITH WATER
- Filling the system:
• Open the heating output/return valves if neces-
sary,
• Open the cold water inlet valve,
• Fill the installation slowly (to aid degassing)
using the disconnector filling valves.
• Close the filling valves again,
• Check that it is watertight,
• Drain the entire installation, including the ra-
diators. Continue to fill until a pressure of
1,5
bar is obtained.
- To FCX with DHW hot water tank:
• When the boiler is under pressure and the hot
water circulating pump is supplied, the water
tank coil will be purged when the circulating
pump is started.
• Filling the tank:
. Fill the tank with water using the safety con-
trol box (rep. 18, fig. 45 - page 28 et fig. 47 -
page 30 - chapter IV - INSTALLATION) of
the system, and making sure a hot water tap
is open,
. When the tank is filled, check that the tank
access door is tightened,
3 - OIL INLET
The burner must be off when filling the

of the various filters from clogging owing to the
suction of deposits disturbed in the tank when it
is filled.
