Before starting the appli-
ance, check that the heating
circuit is full of water and the
appliance is supplied with
gas and electrical power.
î
Check that the gas pressure
is within the allowed range.
î
Check that the water pressure is suffi -
cient (at least 1.2 bar when cold). Low
water pressure is detected by the ap-
pliance sensor and will be indicated on
the control panel display. Top up the
circuit as required.
î
In case of repeated indication of low
pressure in the water circuit, check for
leaks and repair as required.
î
Once the fi lling of the heating circuit is
complete, close the fi lling valve.
î
Check that all connections (electrical,
fl ue pipe, hydraulic, gas) have been
carried out and that they are tight and
secure.
î
Ensure that the condensate trap is full
of water before starting up the appli-
ance.
Conditions:
Procedure:
1. Connect the fi lling hose (
) to the system
fi lling valve (
) and to the water network tap.
2. Make sure that the optional draining valve
(
) installed at the drain connection is closed.
3. Open the isolating valves (
).
4. Open the fi lling valve (
) and the water net-
work tap.
5. Bleed the air from the system, using the man-
ual air vent of the boiler, and bring the system
pressure at minimum 1.2 bar.
Pressure should be suitable for the
size/height of the heating system
and take into account the pressure
rating of the safety valve.
6. Close the fi lling valve (
).
7. Remove the fi lling hose (
) from the fi lling
valve (
) as required.
8. Connect the water network to the DHW inlet circuit.
9. Make sure that the draining valve (
), if in-
stalled, is closed.
10. Make sure that the isolating valves (
) are
open on the DHW inlet and outlet circuits.
11. Open the fi lling valve (
).of the Domestic
Hot Water circuit.
