When initially installing the device qualified persons must perform
the following tests:
- Check that the internal and external parts of the gas supplying
device are sealed;
- check that the gas quantity supplied is equal to that required by
the device;
- check that the device receives the type of gas it is manufactured
to process;
- check that the gas supply pressure does not go beyond the maxi-
mum pressure values displayed on the information plate;
- check that the gas supply system supplies the necessary amount
of gas to the device and that it is equipped with all the necessary
safety devices prescribed by current regulations.
If the user is absent for a lengthy period, turn off the main gas supply tap.
Do not obstruct the area's ventilation openings where the device is
installed to avoid dangers such as the build up of toxic and explosive
substances.
Do not utilize gas tubes to earth electrical devices.
2.f Water connection
Connect the water heater to the water supply and insert a tap to
intercept the water above the device. From the front, the cold water
input is on the right and the hot water output is on the left.
Insert the filter into the water valve input fitting.
Remove the plastic nut from the hot water output fittin before
connecting it to the water supply.
Ensure that the tubes of you water system are not used to earth your
electrical system or telephone, they are absolutely inappropriate for
performing this task.
In a short amount of time this can damage tubes and the device.

2.g Disposal of waste product
This B11BS water heater is supplied with a device for releasing flue
gas.
For output of combustion by-products refer to the regulations in force
including any updates. See paragraph 2.a
The gas devices with an attachment for a waste gas flue must be
connected directly to properly working chimney or flue pipe; only if
these devices are not present is it then permitted to release gases
directly outside.
The fitting of devices to a chimney or flue pipe must occur via a
smoke channel. Smoke channels must be connected to a chimney
or a smoke channel in the same or adjacent area to where the device
is installed and must be made of materials resistant to mechanical
strain, heat and the effects of combustion by-products and their con-
densation. The flue gas temperature must always be above conden-
sation temperature in all points of the smoke channel regardless of
external conditions.
FLUE GAS RELEASE SAFETY DEVICE
The product is equipped with a series of flue gas release safety
devices. The device ensures the correct release of combustion by-
products; the flow of combustible gas to the release conduit and the
smoke channel.
The safety device contains a "thermostat" connected to the electro-
nic devices, it can stop the flow of gas to the main burner or to the
pilot flame. The safety device can be triggered by the partial or total
obstruction of the release conduit or the smoke channel.
To reset the device it is necessary to press the flue gas thermo-
stat key (fig. 7) close use a screwdriver and reopening the hot
water tap.
If the device or its electrical connections breaks down, the machine
operation is blocked. If the machine is constantly blocked as a result
of the flue gas safety device, it is necessary to request the assistan-
ce of a qualified technician according to law in force, to check the
correct release of flue gas through the release conduit and/or the
smoke channel, according to the installation regulation.
It is highly prohibited to attempt to modify or remove the flue
gas safety device; this risks the safety of the user and persons
in the area.
Only a qualified technician who is authorised by the manufacturer
can meddle with the safety device in order to check it's functionality
or to substitute it if necessary.
If it is necessary to replace the device it is vital to only use "ori-
ginal parts" supplied by the manufacturer since it has been de-
signed, studied and regulated to be fitted with the water heater.
2.h Gas transformation
Transforming the product so it may receive a different type of gas
can be easily performed even while it is mounted. The instructions
for transforming and regulating the product to receive various types
of gas are below.
This operation must be performed by qualified personnel according
to law in force.
TRANSFORMATION FROM METHANE TO LPG
Transforming the product so it may receive a different type of gas
can be easily performed even while it is mounted.
Before any operation ensure that the gas supply is switched off.
I – SUBSTITUTION OF THE PILOT INJECTOR
- Disconnect the pilot flame tube (fig. 8)
- remove the pilot injector
- insert the seal contained in the transformation kit (fig. 9),
II – SUBSTITUTION OF THE BURNER INJECTORS
- Remove the screws that hold the pilot flame in position (fig. 10)
- Remove the nut that holds the burner in place (fig. 11)
- Remove the screws that hold the diffuser in place (fig. 12)
- Unscrew the diffuser
- Unscrew the injectors and substitute them with those found in the
transformation kit
III – SUBSTITUTION OF THE MODULATION VALVE
- Loosen the cold water entry ramp nut on the exchanger
- Remove the 4 screws (B) of the gas valve (fig. 13)
- Disconnect the microswitch's cables
- Separate the water/gas valve set
- Extract the large spring and the small spring/modulation valve set
(fig. 14)
- Substitute the modulation valve with the one in the kit
- Insert the valve and the large spring, taking care with the direction
of the insertion (fig. 16) and making sure that the drilled spring
guide disc is in its correct position (fig. 15)
