THE USE OF INJECTORS DIFFERENT THAN THOSE
SPECIFIED CAN ENDANGER PERSONS AND
PROPERTY. CHECK THAT THE BURNER TRAY
PACK AND ALL OTHER PREVIOUSLY REMOVED
COMPONENTS ARE CORRECTLY POSITIONED
BEFORE CONNECTING THE GAS SUPPLY AND
STARTING THE BOILER.
BEFORE COMMISSIONING THE NEWLY
CONFIGURED BOILER IT IS NECESSARY TO CHECK
THE GAS SUPPLY PRESSURE BEFORE THE BOILER
AND MEASURE AND ADJUST THE GAS PRESSURE AT
THE BURNER. REFER TO THE PRESSURE VALUES AND
PROCEDURES GIVEN FOR EACH SPECIFIC GAS IN
THE “GAS PRESSURE CHECK” CHAPTER (PAGE 30)
COMPLETE THE CHANGE BY ATTACHING THE
LABEL A1 OR A2 INDICATING THE CHANGE TO
THE NEW TYPE OF GAS FOR WHICH THE BOILER
HAS NOW BEEN CONFIGURED, SUPPLIED WITH
THE GAS CHANGE KIT, NEAR THE TECHNICAL
DATA PLATE LOCATED ON THE REAR INSTRUMENT
PANEL COVER.
ACCESS TO THE “CONFIGURATION MENU” IS EXCLUSIVELY RESERVED FOR
TECHNICIANS WITH THE NECESSARY QUALIFICATIONS AND LICENSES ARBITRARY
MODIFICATION OF ANY PARAMETER CAN CAUSE MALFUNCTIONING OF AND
DAMAGE TO THE BOILER, AS WELL AS CREATING A DANGEROUS SITUATION FOR
PERSONS AND PROPERTY.
ACCESSING THE CONFIGURATION MENU
It is possible to view information or perform
complete configuration of the boiler by accessing
the different pages of the available menus:
- INFORMATION MENU
- INSTALLER MENU
The INFORMATION MENU is the only one which
exclusively displays information on the state or
presence of devices and does not allow any
modifications to the operational parameters;
From any page of the “MAIN MENU”, press button
“4” for more than 5 seconds. The access to the menu
pages is indicated by a symbol and a page number
flashing alternatively, while the value of the parameter
referred to by that page is displayed normally.
In this mode it is possible to scroll through the pages
for all parameters and read the relative values, but
without the possibility to make changes. To modify
the value of any parameter it is necessary to activate
“Edit” mode by entering the correct security code
which corresponds to the value of menu parameter
P10. (Pict. 39)
Selecting the menu/parameter modification page:
By pressing buttons “5”-“6” the available pages in menu can be scrolled.
Once the required page has been identified, modify
the associated parameter, press the buttons “7”-
“8”: the symbol and page number will be displayed
normally while the value of the parameter flashes.
Modifying the parameter associated with a page:
When the required value of the parameter is displayed,
select it by pressing button “5”. Once the parameter
has been stored the boiler will return to the menu page
selection condition.
The system will automatically exit the INSTALLER MENU
after 30 seconds, or by pressing any button among
“1”-“2”-“3”-“4”, and return to normal display mode.
to access the pages of the information menu,
proceed as described on page 5.
Accessing the INSTALLER MENU, aside
from displaying information on the state
or presence of most of the devices, also
allows the configuration parameters to be
altered, therefore substantially influencing the
device’s operation.
