INSTALLATION
3.1 Standards
The use of gas appliances is subject to strict regulations. It is therefore
important that the UNI 7129 and 7131 standards are observed.
For lique ed petroleum gas (LPG), the installation must comply with the
requirements of the distributing companies and with the requirements of
the standards cited above.
The appliance is sold without the inlet and outlet device as a different device
is required according to the speci c installation; please consult the acces-
sories catalogue to request any of the various different devices.
3.2 Wall mounting
The appliance must be installed on a suitable wall:
- the device should not be closed in a unit or niche; there should be a gap
of at least 20 mm between the side walls and the appliance, so as to
facilitate maintenance work;
- once the position of the appliance has been decided on, make two 8 Ø
holes 320 mm apart for the support template (use the same template to
mark the holes); x with the plugs provided. The most common type of
rear and horizontal outlet is described below; guide the wall template ns
into the slots on the paper template;
- mark the centre of the ue hole;
- make a 110 mm Ø hole as shown on the paper template;
- cut the pipes to the correct length according to the thickness of the wall. If
done correctly, the 60 mm Ø ue should protrude by 7.5 mm with respect
to the 100 mm Ø air duct;
- insert the speci c ue made up of two concentric pipes in the hole in the
wall;
- seal the gap between the 100 Ø pipe and the hole in the wall with ce-
ment-based mortar, positioning a piece of paper so that the tube does not
remain xed to the wall itself, so as to facilitate subsequent disassembly.
Place the appliance in the chosen position, with reference to the meas-
urements indicated in this instruction manual in the
section.

3.3 Positioning
The appliance should be installed on a suitable wall and it is essential
that the minimum spaces be left around it to allow for maintenance work
to be performed (see
The appliance should not be positioned above a stove or other cooking
appliance so as to avoid kitchen vapour grease being deposited on it and
affecting operation.
- Heat-sensitive walls such as those made from wood should be protected
with suitable insulation.
3.4 Evacuating products of combustion
For information on evacuating the products of combustion, please refer to
regulation in force. The ue gas outlet/air intake kit is not supplied with the
boiler as accessories for sealed-chamber forced-draught appliances, which
better adapt to the installation context, can be used.
To extract the ue gas and restore the combustion air in the boiler, use
original tubes or others with the same characteristics which are EC certi ed
and ensure that they are correctly connected as indicated in the instructions
provided with the ue gas accessories.
A single smoke pipe can be connected to several appliances provided that
every appliance is sealed chamber type.
The boiler is a type C appliance (with a sealed chamber) and must there-
fore have a secure connection to the ue gas outlet pipe and combustion
air intake pipe which both ow outside, and without which the appliance
cannot operate.
FORCED OPEN INSTALLATION (B22-B52)
The ue gas outlet pipe can be directed to the most suitable direction
according to installation requirements.
For installation, follow the instructions supplied with the kit.
In this con guration, the appliance is connected to the ue gas outlet pipe
of ø 80 mm through an adaptor of ø 60-80 mm ( g. 1-1a).
In this con guration the combustion air is withdrawn from the room
where the appliance is installed, which should be technically suitable
and ventilated.
The non insulated ue gas outlet pipes are potential sources of dan-
ger.
When necessary, the ue gas ange (C) is to be removed by lifting it using
a screwdriver.
The table indicates the permitted linear lengths.
On the basis of the length of the pipe used, one of the anges
provided should be inserted (see table).

COAXIAL OUTLETS (60-100 Ø)
The boiler has been designed to be connected to concentric outlet/suction
pipes and with the opening for air suction (D) closed.(Fig. 2-2a).
Coaxial outlets can be pointed in the direction most suited to the speci c
installation room, in line with the lengths shown in the table.
Follow the installation instructions supplied with the kit.
