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 installed.
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 instead by means of the room ther-
mostat and the function selector (8 in Fig. 3.1).

3.2

Frost protection

This appliance is provided with a built in anti---
freeze system that operates the boiler when the
temperature is below 5 ûC
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 isola-
tion switch or close the gas inlet cock.
3.3

Condensate drain

The condensate drain must not be modified or
blocked.
Blockage of the condensate drain, caused by de-
bris or freezing, can cause automatic shutdown of
the boiler.
If freezing is suspected and the pipe run is access-
ible an attempt may be made to free the obstruc-
tion 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 assist-
ance of a CORGI registered installer or in IE a com-
petent person should be sought.
3.4

Periodic maintenance

For efficient and continuous operation of the
boiler, it is advisable to arrange maintenance and
10
cleaning by an Authorised Service Centre En-
gineer, at least once a year.
During the service, the most important compo-
nents of the boiler will be inspected and cleaned.
This service can be part of a maintenance con-
tract.
In particular, you are advised to have the following
checks carried out:
--- primary heat exchanger;
--- domestic hot water 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 system;
--- general check of the appliance's operation.
3.5

External cleaning

Before carrying out any cleaning, disconnect the
appliance from the electrical mains, using the
fused spur isolation switch fitted adjacent to the
appliance.
To clean the external panels, use a cloth soaked in
soapy water. Do not use solvents, abrasive powd-
ers or sponges.
Do not carry out cleaning of the appliance and/or
its parts with readily flammable substances (for
example petrol, alcohols, naphtha, etc.).
3.6

Operational faults

If the lock---out signal lamp comes on
this indicates that the safety lock--- out 6 (Fig. 3.2)
has stopped the boiler
To re--- start the boiler, it is necessary to press the
boiler reset button 7 (Fig. 3.2).
