10. SAFETY DEVICE INDICATORS - ACTIVATION
We recommend you avoid draining the whole system as water replacements engender purposeless and harmful limestone
deposits inside the boiler and on the heating elements. In case the boiler is not operated during wintertime and is therefore
exposed to danger of frost we suggest you add some specic-purpose anti-freeze to the water contained in the system
(e.g.: propylene glycole coupled with corrosion and scaling inhibitors).
The electronic management of boilers includes a “frost protection” function in the central heating system which operates
the burner to reach a heating ow temperature of 30° C when the system heating ow temperature drops below 5°C.
The frost protection function is enabled if:
* electrical supply to the boiler is on;
* the gas service cock is open;
* the system pressure is as required;
* the boiler is not blocked.
9. PROLONGED STANDSTILL OF THE SYSTEM. FROST PROTECTION
To RESET the gas boiler, turn selector (Figure 2) to
“R” for at least 2 seconds. If the fault persists, call an
authorised service centre.
Note: It is possible to carry out n° 5 relighting
attempts in a row, after which the RESET
function is disabled and the gas boiler still
blocked.
To carry out a new RESET attempt, turn the
selector (gure 2) in OFF position for at least 2
seconds.
NOTE: if a fault occurs, the display reads out an error code ashing together with background light.
To maintain efcient and safe operation of your boiler have it checked by a Qualied Service Engineer at the end of every
operating period.
Careful servicing will ensure economical operation of the system.
Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily ammable cleaners (i.e.: gasoline,
alcohol, and so on). Always isolate the electrical supply to the appliance before cleaning it (see section 7 “Turning off the
boiler”).
11. SERVICING INSTRUCTIONS
