USEFUL ADVICE

3.1

Central Heating

For reasonably economical service install a
room thermostat. Never shut off the radiator
in the area where the room thermostat is in-
stalled.
If a radiator (or a convector) does not heat
up, check that no air is present in it and that
its valve is open. If the ambient temperature
is too high, do not alter the radiator valves.
Reduce the central heating temperature in-
stead by means of the room thermostat or by
acting on the 15 and 16 heating adjustment
keys (Fig. 3.1).

Frost protection

The anti-freeze system and any additional
protections protect the boiler from possible
damage due to frost.
This system does not guarantee protection
of the entire hydraulic system.
If the external temperature can reach values
lower than 0°C, it is recommended that the
entire system is activated adjusting the room
thermostat at a low temperature.
The anti-freeze function is also activated
with the boiler in stand-by (Fig. 3.2).

Therefore, when the boiler is not lit and
used in cold weather, with consequent risk
of freezing do not switch off the boiler at the
fused spur isolation switch or close the gas
inlet cock.
If the boiler is deactivated, have a qualified
technician empty the boiler (heating and do-
mestic hot water circuit), the c.h. system and
the d.h.w. system.
3.3

Condensate drain

The condensate drain must not be modi-
fied or blocked. Blockage of the conden-
sate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler.
If freezing is suspected and the pipe run is
accessible an attempt may be made to free
the obstruction by pouring hot water over the
exposed pipe an cleaning any blockage from
the end of the pipe.
If this fails to remedy the problem the assis-
tance of a Gas Safe registered installer or
in IE a competent person should be sought.
3.4

Periodic maintenance

For efficient and continuous operation of the
boiler, it is advisable to arrange maintenance
and cleaning by an Authorised Service Cen-
tre Engineer, at least once a year.
During the service, the most important com-
ponents of the boiler will be inspected and
cleaned. This service can be part of a main-
tenance contract. In particular, you are ad-
vised to have the following checks carried
out:
• domestic hot water heat exchanger;
• condensing heat exchanger;
• burner;
• exhaust fume duct and flue;
• pressurisation of the expansion tank;
• filling up of the central heating circuit;
• bleeding of air from the central heating sys-
tem;
• general check of the appliance's operation.
