HELPFUL SUGGESTIONS
To get the most out of your boiler, we have provided you
with some useful advice on the proper use and main-
tenance:
- Periodically check the system pressure using the pres-
sure gauge "O", make sure that the pressure is between 1.0 and 1.5 bar
(the blue part on the gauge) when the system is off and cool.
The warning L.E.D. "D" will indicate if the pressure is below the minimum

recommended value. Consult your installer for checking and refilling the
system.
- The outer panels of the unit's case must only be cleaned with a damp
cloth. Do not use abrasive cleaners. The Control panel can be wiped with
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 effi-
ciency of the unit remains the same over time, as this will consume less gas.
- To improve comfort and take full advantage of the heat produced by the
boiler, it is recommended that an external thermostat be installed.
- If the boiler is not going to be used for an extended
period of time, turn off the supply of electricity to the
unit by pressing the On/Off switch "L".
The green L.E.D. "I" will turn off. Then turn off the
supply of gas to the unit itself.
It is good practice to clean and service the appliance
and central heating system every year.
