Installation, start-up, adjustments and maintenance must be
performed by a competent person only, in accordance with the
current Gas Safety (Installation & Use) Regulations and the
instructions provided. Improper installation may cause damage or
injury to individuals, animals and personal property, for which the
manufacturer will not be held liable.
To ensure efficient and safe operation it is recommended that the
boiler is serviced annually by a competent person.
If it is known or suspected that a fault exists on the appliance, it
must not be used until the fault has been corrected by a competent
person.
HELPFUL SUGGESTIONS
To get the most out of your boiler, we have provided you with some
useful advice on the proper use and maintenance:
- Periodically check the system pressure using the pressure guage
"O", make sure that the pressure at 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 either 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
efficiency 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
I
unit itself.
- It is good practice to clean and service the appliance and central
heating system every year.
- Call an Authorised Service Centre.
START-UP PROCEDURE LIGHTING
Before starting the unit, check the following:
· The water pressure on the pressure gauge "O";

open.
These models are equipped with electronic ignition which utilises
contact ionisation.
To make the boiler operational, simply press the On/Off switch "L".
The green L.E.D. "I" will then turn on.
