1. General Information

This is a combined appliance f or the production of centr al heat-
ing (C.H.) and domestic hot water (D.H.W.). This appliance 

must

be used only for the purpose for which it is designed. The man-
ufacturer declines all liability f or damage caused b y improper or
negligent use.
Do not allow children or inexperienced persons to use the appli-
ance without supervision.
If you smell gas in the room, 

do not turn on light switches, use

the telephone or any other object which might cause spar ks.
Open doors and windows immediately to ventilate the room.
Shut the gas mains tap (on the gas meter) or the valve of the gas
cylinder and call your Gas Supplier immediately.
If you are going away for a long period of time, remember to shut
the mains gas tap or the gas cylinder v alve.

Before any intervention within the boiler it is first necessary
to cut off the electrical power supply by turning the external
switch to “OFF”.

To  get the most out of y our  boiler,  we  have  provided  you  with
some useful advice on proper use and maintenance:
- Periodically  check  the system pressure

using  the pressure gauge 

“D”,  make  sure

that the pressure is at 1.5 bar when the sys-
tem is off and cool. If the pressure is belo w
the minimum recommended value.
Consult your installer for checking and refill-
ing the system.

- The outer panels of the units case must only be cleaned with a

damp  cloth. Do  not use abr asive  cleaners. The  control panel
can be wiped with either a damp or dr y cloth. Spray polishes
must not be used on the control panel surf ace or knobs. Care
must be taken in preventing any liquid entering the appliance.

- If the water is very hard, it is recommended that a water soften-

er  be added to the system so as to reduce the f

ormation  of

limescale in the heat e xchanger. This will ensure that the effi -
ciency  of the unit remains the same o ver  time,  reducing gas
consumption and maintenance costs.

- If the boiler should be out of use f or a prolonged per iod, it is

recommended that the electr ical power supply be disconnect -
ed  and that the e xternal  gas cock  be closed. If  low  tempera-
tures are expected, the boiler and system pipe work should be
drained in order to prevent frost damage.

- To  improve  comfort  and tak e  full adv antage  of the heat pro-

duced by the boiler, it is recommended that an external (room)
thermostat be installed.

- It is good practice to clean and service the appliance and cen-

tral heating  system every year.
Call an Authorised Service Centre.

2. Operating Instructions

Installation, start-up, adjustments and maintenance must be
performed by a competent per son only, in accordance with
the current Gas Saf ety (Installation & Use) Regulations and
the  instructions pr ovided. Improper  installation ma y  cause
damage or injury to individuals, animals and personal prop-
erty, for which the manufacturer will not be held liable.
To  ensure efficient and saf e  operation it is recommended
that the boiler is serviced annually by a competent person.
If it is kno wn or suspected that a fault e xists on the appli-
ance, it must not be used until the fault has been corrected
by a competent person.

Ignition Procedure

Press  button 

“A”. The  green  L.E.D. “K” will

illuminate  indicating that the boiler is ready to
operate. The centralised electronic control unit
will  ignite the b urner,  upon demand f or  either
C.H. or D.H.W. If, after approximately 10 sec-
onds,  the b urner  has not ignited, the boiler
safety devices will shut off the gas and the red
L.E.D.

“I” illuminates. To reset the ignition sys-

tem,  the reset 

“J” must  be pressed and

released. Should the boiler f ail to ignite a sec-
ond  time,  check  that the e xternal  gas coc k  is
open (see diagrams on the left). If the problem
persists, contact a local Service Agent.
