TURNING OFF BOILER
To turn off the boiler set the switch to “OFF”
and close the gas-feeding pipe tap if the boi-
ler remains inoperative for a long period
(fig. 1).
SYSTEM FILLING
(fig. 4)
Check periodically that the thermomanome-
ter shows a reading of between 1 - 1.2 bar
(1), with the system cold.
If the pressure drops below the blue scale
(1), the boiler will not operate.
To re-set the pressure, rotate the char-
ging valve to the anticlockwise direction
until the thermomanometer reading re-
enters the blue scale (1).
Once this operation is completed, make
sure the tap is closed.
In case the pressure goes above the limit,
empty the exceeding pressure by opening
the pressure relief valve on any radiator.
The blue part of the scale (2) indicates the
working pressure range with the heating in
operation. Should the pressure exceed the
values of the blue scale (2), causing the
safety valve intervention, call the authorized
technical staff.
"25 OF - 30 OF" SMOKE
SAFETY DEVICE
This is a safety device against possible
smoke emission into the ambience.
The safety device switches off the gas valve
when the return of the smokes into the
ambience is continuous and then dange-
rous. The intervention of this device locks
out the appliance because the burner is not
ignited. In this case, turn the rotary switch
to the
position (fig. 3) nd release it imme-
diately, then turn it back to the summer
or winter
.
Should the boiler “lock out” again, you
must call the authorized technical staff.
GAS CONVERSION
Should it be necessar y t o conver t the
appliance to a different gas from the one
for which the boiler has been equipped,
approach the technical staff.
CLEANING AND MAINTENANCE
At the end of each heating season, it is
essential to have the boiler thoroughly
checked and cleaned out.
Preventive maintenance and checking of
the efficient operation of the equipment
and safety devices must be carried out
exclusively by the authorized technical
staff.
The boiler is supplied with an electric
cable. Should this require replacement,
contact exclusively with the authorized
technical staff.
TIME PROGRAMMER (optional)
With the selector in the
“AUTO”
position,
the boiler operation is regulated according
to the temperatures set for the program-
med time periods.
During start-up, the second selector must
be in the
“RUN”
position. Programming:
–
Setting the time
(fig. 5)
Move the selector to
“
”
. To change the
hour on the display, press the
“h”
button,
to change the minutes, press the
“m”
button.
To set the day, press button
“1...7”
until
the arrow points to the correct day (1 =
Monday ....... 7 = Sunday).

Setting the programme
(fig. 6)
The programmer has 8 start-up pro-
grammes and 8 shutdown options.
To make programming easier, 3 start-up
and 3 shutdown programmes have
already been set up for each day of the
week, as follows:
NOTE:Programmes from 7 to 16 are not
pre-set.
To select programmes other than those
pre-set, move the selector to the
“P”
position: “0:00 1” will appear on the
display: the first three figures indicate
the hour and minutes, the fourth figure is
the number of the programme.
Programmes with odd numbers are swit-
ch-on times (daytime temperature) and
are indicated on the display by a light bulb
symbol. Programmes with even numbers
indicate the temperature reduction
(night).
Use button
“1...7”
to select the day of the
week (from 1 to 7), or the period (1 ÷ 5,
6 - 7; 1 ÷ 6; or every day if the program-
me has to be repeated every day of the
week). Set the hour and minutes using
buttons
“h”
and
“m”
.
