N.W.:
Pressure values speci ed in the table indicate the dif-
ference of pressure values between the gas valve outlet and
the combustion chamber. Ad just ments are therefore carried
out with the di erential pressure gauge ( “U” or digital type)
with the sensors inserted in the test pressure outlet of the
modulating adjustable gas valve and on the sealed chamber
pos i tive pressure test outlet . Power data speci ed in the
table refer to a 0,5 metre intake/exhaust pipe. Gas  ow rates
refer to heat power below temperature of 15°C and at a
pres sure of 1013 mbar. Burner pres sure values refer to use
of gas at 15°C.
Annual appliance maintenance.
 e following checks and maintenance should be per formed
at least once a year.
-
Clean the  ue side of the heat exchanger.
-
Clean the main burner.
-
Make a visual inspection of the  ue extraction hood for
wear or corrosion.
-
Ensure correct ignition and operation.
-
Ensure correct settings of the burner.
-
Verify correct operation and adjustments of the ap pli ance,
in particular:
-
activation of the electrical main switch on the boil er;
-
activation of the system control thermostat.
-
Ensure sealing e ciency of the gas intake circuit; insert a
“U” or digital type pressure gauge in the pressure socket
upstream of the gas valve and sub se quent ly closing the
boiler shuto valve (cock) and closing the gas valve, no
pressure variation must occur in the next  ve minutes on
the gauge.
-
Ensure activation of the device for protection against the
ionisation  ame control gas; ac ti va tion time must be less
than ten seconds.
-
Visually inspect to check for leakage of water or oxidation
of relative couplings.
-
Check visually that the water safety drain valve is not
blocked.
-
Check that the charge of the expansion vessel af ter dischar-
ging system pressure to the zero set ting (check via boiler
pressure gauge), is at 1 bar.
-
Check that the system static pressure (in cold con di tions
and after system recharging via the  lling valve ) is between
1 and 1,2 bar.
-
Check visually that the safety and control devices have not
been tampered with and/or shorted, in par tic u lar:
-
temperature safety thermostat;
-
air pressure switch.
-
Ensure correct maintenance and condition of the electrical
installation with particular reference to:
-
electrical cables must be inside the channels;
-
no traces of black marking or burns.
