OPERATING INSTRUCTIONS
O
F
CAUTION!!
In the United Kingdom installation, start-up, adjustments
and maintenance must be performed by a CORGI registered
installer in accordance with the installation standards cur-
rently in effect, as well as with any and all local health and
safety standards i.e. CORGI.
In the Republic of Ireland the installation, and initial start-up
of the appliance must be carried out by a Competent Person
in accordance with the current edition of I.S.813 " Domestic
Gas Installations", and the current Building Regulations,
reference should also be made to the current ETCI rules for
electrical installation.
Improper installation may cause damage or injury to individuals,
animals and personal property, for which the manufacturer will
not be held liable.
To ensure efficient and safe operation it is recommended that the
boiler is serviced annually by a competent person.
If it is known or suspected that a fault exists on the appliance, it
must not be used until the fault has been corrected by a compe-
tent person.
Helpful Suggestions
To get the most out of your boiler, we have provided you with some use-
ful advice on proper use and maintenance:
- Periodically check the system pressure using the pressure gauge "F"
and make sure that the pressure is between 1.0 and 1.5 bar when the
system is off and cool. If the pressure is below the minimum recom-
mended value, the pressure must be brought into the acceptable
range. To refill the system, connect the flexible hose to the cold water
inlet and central heating flow, open the two black handles connected
to the silver flexible hose, once the pressure gauge "F" reads 1.5 bar
close the valves again and disconnect the flexible hose.
If the pressure level drops on a frequent basis, it is likely that there is
a water leak in the system. If this is the case, your installer must
inspect the system.
- The outer panels of the boiler's case must only be cleaned with a
damp cloth, do not use abrasive cleaners. The control panel can be
wiped with either a damp or dry cloth. Spray polishes must not be
used on the control panel surface or knobs. Care must be taken in
preventing any liquid entering the appliance.
- If the water is exceptionally hard, install a water softener so that the
efficiency of the boiler remains the same over time, as this will con-
sume less gas.
- To improve comfort levels and take full advantage of the heat pro-
duced by the boiler, it is necessary that an external thermostat and an
outdoor sensor be installed.
- When the boiler is not in use for prolonged periods shut it down by
pushing the
button to the off position and close the gas and
water isolation valves.
(Important!) This will disable the anti-frost device (see page 9) - if the
period of disuse is very cold it will also be necessary to drain the heat-
ing system of water.
If you wish to leave the anti-frost device active, it is necessary to leave
the boiler on: this will not safeguard from possible interventions which
may impair this function.
- It is good practice to clean and service the appliance and Central
Heating System every year.
