ensure that the efficiency of the unit remains the same over time, reducing gas
consumption and maintenance costs.
-
If the boiler should be out of use for a prolonged period, it is recommended that the
electrical power supply be disconnected and that the external gas cock “M” and “N”
be closed.
If low temperatures are expected, the boiler and system pipe work should be
drained in order to prevent frost damage.
- To improve comfort and take full advantage of the heat produced by the boiler, it is
recommended that an external (room) thermostat be installed.
- It is good practice to clean and service the appliance and central heating system every
year. Call an Authorised Service Centre.

A
PL004D
In the ‘winter’ operating mode, the boiler will produce both Central
Heating and Domestic Hot
Water. In the ‘summer’ operating mode, the
boiler will produce only Domestic Hot Water.
Using the knobs on the control panel, the user can select ‘winter’ or ‘summer’ operating
mode.
Keeping the knob “C”
at the “
” position selects the ‘summer’
operating mode, the symbol “ “ will illuminate. ‘Winter’ operating
mode may be selected by positioning the knob
“C” between the

“ will illuminate.
ADJUSTING THE HEATING
It is possible to set the temperature of the Central Heating system
by adjusting the knob “C”. By positioning the indicator somewhere
betw
een min.
and max., a temperature may be obtained which
v
ar
ies from approximately 42˚C to about 82˚C
.
The water temperature in the Central Heating circuit may be
chec

EXTERNAL (ROOM) THERMOSTAT CONTROL
If an external (room) thermostat is installed, it is recommended that the temperature of
the Central Heating system be set by means of the “C” knob, leaving it at max in order
to obtain the best performance from the boiler and to allow the regulation of the external
temperature to function efficiently.
SETTING THE HOT WATER FOR DOMESTIC USE
Both in the winter and summer mode, the temperature of the Domestic Hot Water may be
adjusted by using the “B” knob
.
A deliv

y temperature f
or the water may be chosen in a
r
ange from 36˚C to about 56˚C, depending on the flo

of the knob between the min.
and max. settings.
The water temperature in the primary circuit may be checked on the display.

:
Should the hot water temperature be insufficientm turn the thermostat
knob to maximum and reduce the flow rate at the tap. ( A high flow rate will
reduce the temperature.
