USEFUL ADVICE

3.1

Central Heating

For your comfort and added system control,
you can install a room thermostat but you
should not shut off the radiator in that room
or have a TRV fitted on the radiator.
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 pressing the 13 and 14 heating adjust-
ment keys (Fig. 3.1).

Frost protection

The built in anti frost system protects the
boiler from frost damage but does not pro-
vide any protection for the system, an op-
tional external frost protection thermostat
can be added and a dedicated connection
point is available on the electrical connec-
tion block.
The antifreeze function is active even if the
boiler is in OFF (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 circuit),
the C.H. system.
3.3

Condensate drain

The condensate drain must not be modi-
fied or blocked. Blockage of the condensate
drain, caused by debris or freezing, can
cause automatic shutdown of the boiler. If
freezing is suspected and the pipe run is ac-
cessible 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 mainte-
nance and cleaning by an Authorised Ser-
vice Centre Engineer, at least once a year.
During the service, the most important
components of the boiler will be inspected
and cleaned. This service can be part of a
maintenance contract. In particular, you are
advised to have the following checks car-
ried out:
• condensing heat exchanger;
