6.5 - Ignition
1.- open the gas cock;
2.- power the boiler electrically;
3.- adjust the temperature required from the heating service
using the and keys. The icon , present
on the display will inform regarding the operating state of
the heating service:
a) fixed icon : central heating inactive (check that
the room thermostat is in call mode or, in the case of
external mode, that the external temperature is lower
than the central heating switch-off external temperature
(par
2020
);
b) flashing icon : means that the central heating mode
is operating.
4. - adjust the temperature required for the domestic hot water
service using the and keys. The icon
, present on the display will inform regarding the operating
state of the domestic hot water service:
a) fixed icon : domestic hot water inactive (no-one
is withdrawing domestic hot water, or in the case of
a indirect water heater, the delivery temperature is
reached)
b) flashing icon : domestic hot water is being withdrawn.
5.- if the icon flashes, but the radiators do not heat-up,
it may mean that the pump (see figure 3.1 detail “25”) is
blocked. It must be unblocked by operating on the relevant
screws. To do this remove screw “26” in figure 3.1 and turn
the screw below to unblock the pump;
6.- if the icon flashes but the radiator still does not heat
up, bleed the air from the radiators again.
6.6 - Controlling the supply gas
pressure and any adjustment
The gas supply pressure must correspond to that stated in
the table in chapter 9 at the end of the manual.
Proceed as follows to verify:
1.- close the gas cock;
2.- access the components inside the boiler, following the
procedure in chapter 8.2;
3.- loosen the pressure point “A” (see figure 6.8);
4.- connect to a manometer with resolution of at least 0,1
mbar (1 mmH2O);
5.- open the gas cock;
6.- check that the pressure does not exceed the value given
in the table in chapter 9 under “gas supply maximum
pressure”;
7.- make sure that any cocks and thermostatic valves
downstream from the central heating circuit are open;
ATTENTION !!! During forcing of the delivery
temperature, it automatically goes to 93°C to give the
possibility to dispose of as much of the heat generated
by the boiler as possible. Check that the central heating
plant can support this temperature.
8.- press the and RESET keys simultaneously
for more than 5 seconds to enter the “installer” menu,
confirmed by the appearance of the icon on the
display.
9.- using the and keys, access the
parameter
2010
;
10.- press the RESET key to enter the parameter and use the
and keys to modify the value to
HIgH
;
11.- press the RESET key to confirm the modification. Now
the burner will operate at maximum power for 10 minutes.
12.- check that the pressure does not drop to a value
lower than the “gas supply minimum pressure” given in
the table in chapter 9. If the supply pressure does not
respect the values described, operate upstream from the
appliance in order to take it back within the minimum and
maximum field;
13.- once the control has ended, press the RESET key
again to enter parameter
2010
and via the
and keys, change the value to
OFF
;
14.- press the RESET key to confirm the modification;
15.- hold the RESET key down for 5 seconds to exit the
“installer” menu;
16.- close the pressure point “A” in figure 6.8;
17.- check for any gas leaks from the point with relevant
control methods.
ATTENTION !!! Perform the leak test using a soap
and water only. The use of naked flames is prohibited.
