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 fi 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).
- Make sure that there are no obstacles inside fl ue
exhaust and that it does not contain any discharge
from other appliances, unless the fl ue is meant to
serve more than one user (in accordance with current
legal requirements).
- Where there is already a connection to existing fl ue
exhausts, check that these exhausts have been
perfectly cleaned and are without residues, because
any disconnection could obstruct the passage of
fumes and create potentially dangerous situations.
- Make sure that, where unsuitable fl ue exhausts are
attached, they have been ducted.
- In areas with particularly hard water, limescale may
build up on the components inside the appliance and
reduce its overall effi ciency.
B11bs-type appliances are open-chamber versions
designed to be connection to a fl ue gas discharge duct
which releases fumes towards the outside; combustion
air is taken directly from inside the room in which the
boiler is installed.
Flue gas is discharged through a natural draught
system.
This type of appliance cannot be installed in a
room that does not meet appropriate ventilation
requirements.
So that the normal operation of the appliance is not
compromised, the place in which it is installed must be
suitable with regard to the operating limit temperature
value and the appliance should be protected so that
it does not come into direct contact with atmospheric
agents.
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!!
The installation and fi rst ignition of the appliance
must be performed by qualifi ed personnel in
compliance with current national regulations
regarding installation, and in conformity with any
requirements established by local authorities and
public health organisations.

WARNING!!
No infl ammable 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.

Installation location

Observe the regulations in force, when deciding where
to install the device.
Install the appliance in a PERFECTLY VERTICAL
POSITION.
The device must not be installed near heat sources.
Do not install the device in environments where
temperatures may reach 0°C
For installation inside furniture, consider that the
maximum temperature of the device jacket is lower
than 85°C and distances required for maintenance
must be respected.

Gas connection

The appliance was designed to use gases belonging to
the categories as shown in the following table.
COUNTRY MODEL
FAST EVO ONT B 11
South African FAST EVO ONT B 14
FAST EVO ONT B 16
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
out in compliance with specifi c legal requirements and in
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
is suitable, because if it is insuffi cient the power of the
generator may be reduced, causing inconvenience for
the user.
