WHEN CHOOSING THE APPLIANCE INSTALLATION
SITE.
Before installing the appliance
The appliance heats water to a temperature below boiling.
It should be connected to a a domestic water mains
supply, that must correspond in size to the performance
and its power of the appliance.
Before connecting the appliance, it is rst necessary to
perform the following operations:
- Carefully wash the system piping in order to remove
any screw thread or welding residues, or any dirt which
might prevent the appliances from operating correctly.
- Make sure that the appliance is set up for operation with
the type of gas available (read the information on the
packaging label and on the boiler data plate).
- In areas with particularly hard water, limescale may build
up on the components inside the appliance and reduce
its overall efciency.

The appliance must be installed on a solid, non-
combustible, permanent wall to prevent access from the
rear.
When creating a space for the boiler, the minimum
distances (which ensure that various parts of the appliance
may be accessed after it has been installed) should be
respected.
WARNING!!
NO INFLAMMABLE ITEMS SHOULD BE
LEFT IN THE VICINITY OF THE APPLIANCE.
MAKE SURE THE INSTALLATION SITE
AND ANY SYSTEMS TO WHICH THE
APPLIANCE MUST BE CONNECTED ARE
FULLY COMPLIANT WITH THE CURRENT
APPLICABLE LEGISLATION.
IF DUST AND/OR AGGRESSIVE VAPOURS
ARE PRESENT IN THE ROOM IN WHICH
IT IS TO BE INSTALLED, THE APPLIANCE
MUST OPERATE INDEPENDENTLY OF THE
AIR INSIDE THE ROOM.
WARNING!!
THE INSTALLATION AND FIRST
IGNITION OF THE APPLIANCE MUST BE
PERFORMED BY QUALIFIED PERSONNEL
IN COMPLIANCE WITH CURRENT

Minimum clearances
In order to allow easy access to the appliance for
maintenance operations.
The appliance must be installed in accordance with the
clearances stated below.

Gas connection
The appliance was designed to use gases belonging to
the categories as shown in the following table.
COUNTRY MODEL CATEGORIES
LPG
Make sure, using the labels on the packaging and the
data plate on the appliance itself, that the appliance is in
the correct country and that the gas category for which
the appliance was designed corresponds to one of the
categories available in the country where it will be used.
The gas supply piping must be created and measured
accordance with the maximum power of the appliance;
you should also make sure that the shut-off valve is the
right size and that it is connected correctly.
Before carrying out the installation, it is recommended
that the fuel pipes are cleaned thoroughly in order to
remove any residues which could prevent the appliance
from operating correctly.
Check that the supplied gas corresponds to the type of
gas for which the appliance was designed (see the data
plate located on the appliance itself).
It is also important to check that the pressure of the gas
(methane or LPG) you will be using to feed the appliance
generator may be reduced, causing inconvenience for the
user.
Water connection
The illustration shows the connections for the water and
gas attachments of the appliance.
Check that the maximum water mains pressure does not
exceed 8,5 bar (see technical data page 27); if it does, a
pressure reducing valve must be installed.
Ensure that the minimum pressure is not lower than
0,1 mbar.

a thorough check of the electrical system.
The manufacturer is not responsible for any damage
caused by the lack of a suitable earthing system or by the
malfunctioning of the electricity mains supply.
Make sure that the system is able to withstand the
maximum power absorbed by the appliance (this is
indicated on the appliance data plate).
Check that the section of the wires is suitable and is not
less 0,75 mm2
system if it is to operate correctly.
The power supply cable must be connected to a
230V-50Hz network, where the L-N poles and the earth
connection are all respected.
If the supply cord is damaged, it must be replaced by a
special cord or assembly available from the manufacturer
or its service agent.
The use of multiplugs, extension leads or adaptors is
strictly prohibited.
It is strictly forbidden to use the piping from the hydraulic,
heating and gas systems for the appliance earthing
connection.
The appliance is not protected against the effects caused
by lightning. If the mains fuses need to be replaced, use
2A rapid fuses.

Important!
Connection to the electricity mains supply must
a mobile plug) and a bipolar switch that provide
full disconnection under overvoltage category III
conditions.
Remote control
The appliance is supplied with a Remote Control and the
corresponding connection cable (30 m).
Positioning the Remote Control
Make sure that:
- the remote control cannot be accessed by children
- it is NOT installed near sources of heat
- it is NOT installed in areas which could become wet
(spraying).
Separate
the wall in the chosen area, using the screws supplied
with the appliance.
If necessary, cut the cable supplied to the desired length
and apply the connectors supplied in the package to
ensure power is supplied properly and safely.
Remote Control connection
Proceed as follows:
- disconnect the appliance from the electricity supply by
switching the external bipolar switch to OFF.
- remove the casing as indicated in par. “Instructions for
opening the casing and performing internal inspection”.
- insert the cable into the appliance, via cable gland L.
- connect the cable to the P.C.B. – see electrical diagram
on following page.

Ignition procedure
Press the ON/OFF key placed
on the control panel, to display
the set temperature.
For temperature adjustments
see the User Manual paragraph.
Initial procedures
To guarantee safety and the correct operation of the
appliance, it must be prepared for operation by a qualied
technician who possesses the skills which are required
by law.
Electricity supply
- Check that the voltage and frequency of the electricity
supply correspond to the data shown on the appliance
data plate;
- Make sure that the earthing connection is efcient.
Filling the hydraulic circuit
Proceed in the following manner:
-Gradually open the valve located on the cold inlet;
-open a D.H.W. tap.
WARNING!!
DO NOT USE THE APPLIANCE WITHOUT
WATER.
Gas supply
Proceed in the following manner:
- Make sure that the main gas supply uses the same
type of gas as indicated on the appliance data plate;
- Open all doors and windows;
- Make sure there are no sparks or naked ames in the
room;
- Make sure that the system does not leak fuel using
a cut-off valve inside the applianceitself which should
be closed and then opened while the gas valve is
disabled. The meter must not show any signs of gas
being used for 10 minutes.
First ignition
The rst start-up must be carried out by a
qualied technician.
1. Make sure that:
- The gas valve is closed;
- The electrical connection has been properly carried
out. Make sure that, in any case, the green/yellow
earthing wire is connected to an efcient earthing
system;
- The exhaust duct for combustion products should
be suitable and free from any obstructions;
2. Switch on the appliance (by pressing the ON/OFF
button)
3. Open a D.H.W. tap.
4. The appliance indicates the ignition lock failure
5. Close the D.H.W. tap.
6. Hold down the ON / OFF button. The appiance starts
the RESET procedure. Release the button as soon
as RESET message appears on the display.
7. Open the gas valve and check the connection seals,
including the appliance connection seals, making sure
that the meter does not detect any passage of gas.
Eliminate any leaks.
8. Start the appliance by opening a D.H.W. tap.
WARNING!!
Water with a temperature higher than 50°
cause serious burns.
Always verify water temperature before
use.
