1. GENERAL INFORMATION
This is a combined appliance for the production of central heating (C.H.) and
domestic hot water (D.H.W.).
This appliance must be used only for the purpose for which it is designed.
The manufacturer declines all liability for damage caused by improper or
negligent use.
Do not allow children or inexperienced persons to use the appliance 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 sparks.
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 valve.
Before any intervention within the boiler it is first necessary to cut off the
electrical power supply by turning the external switch to “OFF”.
This manual may be kept in the front panel of the boiler.

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 “J” and 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.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 system. If this is the case, your installer must inspect the system.
2. OPERATING INSTRUCTIONS
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 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.

- The outer panels of the boiler'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 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 recommended that an external thermostat be installed.
A programmable timer for the thermostat is also recommended to schedule
when the boiler will turn on and off during the course of the day (or week), and
an outdoor sensor to optimise operating times.
- When the boiler is not in use for prolonged periods shut it down by pushing
button “E”, the red light “D” will go out; close the gas and water isolation
valves.
IMPORTANT!
This will disable the anti-frost device - if the period of disuse is very cold it will
also 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 safeguard from possible "blocks" which may impair this
function.
- It is good practice to clean and service the appliance and central heating
system every year.
