VI - COMMISSIONING
1 - FILLING THE SYSTEM WITH WATER
WARNING: Health risk from contamina-
ted domestic water!
Always observe the regulations and
standards applicable in your jurisdic-
tion for the prevention of contamination
of drinking water (e.g. by water from
heating systems).
CAUTION: Risk of damage to system
due to material stress caused by tempe-
rature differentials!
Only fill the heating system when cold.
- 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 filling system.
• 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 (22 Psi) 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
control box 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,
2 - OIL INLET
The burner must be off when filling the
tank with oil. Only start it up after a mi-
nimum time of one hour to prevent any
of the various filters from clogging owing to the
suction of deposits disturbed in the tank when it
is filled.
3 - PRE-COMMISSIONING CHECK
- Check that the boiler is filled with water and under
pressure (1,5 bar=22 Psi) and that there are no
leaks,
- Fill the entire water system with water, treated as
desired for the application, including anti-freeze
solution if appropriate. Open any shut-off valves
in the system.
- Check that the electrical connection of the boiler
is correct: 120 V, 60 Hz, connection to earth in
conformity, polarities respected,
- Check that the combustion product drainage flue
is correctly assembled, airtight and free of all obs-
tructions.
- Check that the ventilation units in the heating sys-
tem are free from any obstructions and that they
conform to the necessary regulations.
- Check that the condensate siphon of the flues is
filled with water (filled via the condenser cover),
- Check that the condensate outlet is connected
properly and that there are no leaks.
- Leak-check the fuel oil supply system and open
any fuel shut-off valves.
4 - USER INFORMATION
It is up to the installer to inform the user as to how to
use the appliance. In particular, the user must be in-
formed about the safety devices and their use and
about the need for regular maintenance by a quali-
fied professional.
