11. To save gas and for improved appliance
performance, we recommend leaving the
thermostat in position corresponding (
fi
g.
15) (approx. 60°C). As well as such tempe-
rature and in the presence of particularly
hard waters (waters with excessive lime
scale percentage), limestone deposits in-
side the water heater, are reduce.
2. Ensure the plant hot water cocks are per-
fectly sealed in that any dripping means
gas consumption and increase of the wa-
ter temperature, with consequent forming
of steam.
• It is essential to empty the appliance if
the same has to remain unused in premi-
ses subject to frost.
• The water heater is equipped with a ma-
gnesium anode mounted in boiler. The du-
ration of the anode is proportional to the
average temperature, the chemical com-
position of the water and the amount of
withdrawals. The anode mounted in fac-
tory is envisioned for an e
ffi
ciency of ap-
prox.
fi
ve years, in average working con-
ditions. It is, however, preferable to check
the anode every 18-24 months, bearing in
mind that it must have a su
ffi
ciently even
surface. When the diameter falls below 10-
12 mm, we recommend replacing it with
an original anode.
NB: The anode is mounted underneath the
white boss, located in the upper part of the
appliance.
3. For correct maintenance (to be carried out
regularly at least once a year), we recom-
mend:
• checking the seal of the gas part with
eventual replacement of the gaskets
• visually checking the general status of
the appliance and of the combustion
• checking the combustion chamber and,
eventually, clean the burner, the noz-
zles and the thermocouple.
• verifying the correct gas
fl
ow
• verifying the functioning of the water
safety systems (temperature and pres-
sure limit, hydraulic valve)
• verifying the functioning of the gas sa-
fety systems (gas valve, no gas or
fl
ame,
etc...)
• verifying the state of the fumes de
