This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler must be
connected to a central heating system and/or to a domestic hot water supply system in compliance with its performances
and output power.
The boiler must be installed by a Qualied Service Engineer and ensure the following operations are carried out:
a) Check that the boiler is t for operation with the type of gas available. For more details see the notice on the packaging
and the label on the appliance itself.
b) Careful checking that the ue terminal draft is appropriate; that the terminal is not obstructed and that no other appliance
exhaust gases are expelled through the same ue duct, unless the ue is especially designed to collect the exhaust gas
coming from more than one appliance, in conformity with the standards and regulations in force.
c) Careful checking that, in case the ue has been connected to pre-existing ue ducts, thorough cleaning has been carried
out in that residual combustion products may come off during operation of the boiler and obstruct the ue duct.

INSTRUCTIONS PERTAINING TO THE USER
To shut down the boiler switch off the electrical supply to the appliance.
IMPORTANT: Regularly check that the pressure displayed by the pressure gauge is 1 ÷ 4 bar when the central
heating system is cold. Open the boiler drain cock to reduce pressure if it is too high. Open the lling cock to
increase pressure if it is too low.
Always open the lling cock very slowly to allow any air to bleed off.
If the pressure in the system drops frequently, contact an authorised service centre to have the system checked.
We recommend you avoid draining the whole system as raw water makeup will lead to harmful limestone deposits inside the boiler and on the heating elements.
In case the boiler is not operated during wintertime and is therefore exposed to danger of frost we suggest you
add some specic-purpose anti-freeze to the water contained in the system (e.g.: propylene glycole coupled
with corrosion and scaling inhibitors).
The electronic management of the boilers includes a “frost protection” function in the central heating system
which operates the burner to reach a heating ow temperature of 30° C when the system heating ow temperature drops below 5°C.
The frost protection function is enabled if:
* electrical supply to the boiler is on;
* the gas service cock is open;
* the system pressure is as required;
* the boiler is not isolated.
To maintain efcient and safe operation of your boiler have it checked by a Qualied Service Engineer at the
end of every heating season.
Careful servicing will ensure economical operation of the system.
Do not clean the outer casing of the appliance with abrasive, aggressive and/or easily ammable cleaners
(i.e.: gasoline, alcohol, and so on). Always isolate the electrical supply to the appliance before cleaning it (see
section 5 Turning off the boiler).
These boilers are produced for natural gas and can be converted to work with LPG (G 31).
Any gas change must be effected by a Qualified Service Engineer.

INSTRUCTIONS PERTAINING TO THE INSTALLER
This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler
must be connected to a central heating system and/or to a domestic hot water supply system in compliance
with its performances and output power.
IMPORTANT! The following components are not installed in the boiler as supplied. It is the installer’s
responsibility to provide them:
• Expansion vessel;
• Pressure safety valve;
• Circulation pump;
• Filling system cock.
Before connecting the boiler ensure the following operations have been completed:
a) Check that the boiler is t for operation with the type of gas available. For more details see the notice on the
packaging and the label on the appliance itself.
b) Check that the ue terminal draft is appropriate; that the terminal is not obstructed and that no other applian-
ce exhaust gases are expelled through the same ue duct, unless the ue is especially designed to collect
the exhaust gas coming from more than one appliance, in conformity with the standards and regulations in
force.
c) Check that, in case the ue has been connected to pre-existing ue ducts, thorough cleaning has been carried
out in that residual combustion products may come off during operation of the boiler and obstruct the ue
duct.
The following remarks and instructions are addressed to Service Engineers to help them carry out a faultless
installation. Instructions regarding lighting and operation of the boiler are contained in the ‘Instructions pertaining to the user’ section.
Note that installation, maintenance and operation of the gas appliances must be performed exclusively by
qualied personnel in compliance with current standards.
Please note the following:
• Install the boiler in a permanent ventilated central heating boiler room.
• This boiler can be connected to any type of convector plates, radiators, thermoconvectors. Design the system
sections as usual though taking into account the available output / pump head performances, as shown in
chapter 10.4.
• Do not leave any packaging components (plastic bags, polystyrene, etc.) within children’s reach as they are
a potential source of danger.
• Initial lighting of the boiler must be effected by a Qualied Service Engineer.
• Make sure that the room where the boiler is installed has a sufcient supply of air to ensure complete combu-
stion of the gas consumed by the appliance. Install unblockable ventilation grilles as necessary in accordance
with the Rules in force.
• Connect the boiler directly to an efcient ue to vent all fumes and combustion gases outdoors. Make sure
that the pipe connecting the boiler to the ue is not smaller in diameter than the boiler’s ue outlet. Make
sure that the ue is in good condition and free from holes or cracks that could reduce draw.
Failure to observe the above will render the warranty null and void.

10. BOILER INSTALLATION AND DIMENSIONS
Install the boiler in a position that ensures easy maintenance. You must be able to fully open the front access
door and have adequate access to the rear of the boiler.
If possible, install the boiler on a raised base of 200 mm in height to facilitate drainage of ue condensate.
When calculating the weight of the boiler on the oor, bear in mind the weight of the water in the heat exchanger
(see table 1).
Adjust the levelling feet to compensate for any unevenness in the oor.
Install the necessary utility connections starting from the water and gas connections on the rear of the boiler
(see table 1 for tting type and size).
These appliances do not have any circulation pump, expansion tank or safety valve. These devices
must therefore be provided elsewhere in the system, and must be sized to suit the system’s thermal
capacity.
Connect the ue condensate drain pipe to a suitable water drain, ensuring an adequate slope.
To drain the boiler, use the drain tap at the rear.
To ensure correct operation of the appliance and avoid invalidating the warranty, observe the following
precautions:
