CAUTION!!
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 indi-
viduals, 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 annu-
ally 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 proper use
and maintenance:
- Periodically check the system pressure using the pressure gauge "E" and make sure that the
pressure is between 1.0 and 1.5 bar (the blue part
cool. If the pressure is below the minimum recommended value, the pressure must be brought
into the acceptable range. Consult your installer for checking and refilling the system.
If the pressure level drops on a frequent basis, it is likely that there is a water leak in the sys-
tem. If this is the case, your installer must inspect the system.
- The outer panels of the boiler's case must only be cleaned with a damp cloth, do not use abra-
sive 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 boiler
remains the same over time, as this will consume less gas.
- To improve comfort levels and take full advantage of the heat produced by the boiler, it is nec-
essary that an external thermostat and an outdoor sensor be installed.
- When the boiler is not in use for prolonged periods shut it down by turning the knob "A" to the
off position and close the gas and water isolation valves.

be necessary to drain the heating system of water.
If you wish to leave the anti-frost device active, it is necessary to leave the boiler on: this will not

- It is good practice to clean and service the appliance and Central Heating System every year.
