1.
Check the silicone hose connection
(1)
between the
pump's automatic air vent and the hydraulic console.
2.
Fill with water until the required filling pressure is
reached.
–
Recommended filling pressure: 1 to 1.5 bar
◁
The heating and hot water functions cannot be activ-
ated.
◁
The pressure value flashes in the display until a
pressure of 0.05 MPa (0.5 bar) or higher has been
reached.
◁
An automatic air vent function is activated if the
pressure exceeds 0.05 MPa (0.5 bar) for longer than
15 seconds.
3.
Purge each radiator until the water escapes normally,
and then retighten the system's purging valves.
4.
Check that all connections are leak-tight.
Condition
: If the noise persists in the boiler
▶
Purge the product again by activating check programme

.
3.
Fill the lower section of the condensate trap with water
up to 10 mm below the upper edge of the condensate
discharge pipe.
4.
Re-insert the float

Note
Check that the float is present in the con-
densate trap.
5.
Clip the lower section of the condensate trap

Filling the domestic hot water circuit
1.
Open the water tap to fill the domestic hot water circuit.
2.
Close the water tap once the appropriate volume of
water has flowed out.
◁
The domestic hot water circuit is filled.
3.
Check all connections and the entire system for leak-
tightness.

Checking the gas flow rate
The gas flow rate has been set during production and does
not require adjustment. With the front casing fitted check the
gas flow rate of the boiler as follows:
▶
Start up the product with the check programme
P.01
.
▶
In addition, ensure that maximum heat can be dissipated
into the heating system by turning up the room thermo-
stat.
▶
Wait at least 5 minutes until the boiler has reached its
operating temperature.
▶
Ensure that all other gas appliances in the property are
turned off.
▶
Measure the gas flow rate at the gas meter.
▶
Compare the measured values with the corresponding
values in the table.
