2.e Gas Connection
See paragraph 2.a
Determine the pipe diameter according to current regulations.
Before installing the device blow in the gas pipe to eliminate any
residue from its manufacturing. Connect the water heater to the
internal system's gas pipes and place a tap above the device for
the halting and release of gas.
The water heaters that are powered by tanks of L.P.G. gas with
regulation and interception devices, must be connected correctly
so to guarantee the safety of persons and the surrounding area.
Follow all related regulations.
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 ma-
ximum 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 explosi-
ve 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 in-
tercept 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 inappro-
priate 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 chim-
ney 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 condensation. The flue gas temperature must always be
above condensation 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", it can stop the flow of
gas to the main burner and 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 ther-
mostat key (Fig. 7) close use a screwdriver and reopening the
hot water tap.
If the device or its electrical connections breaks down, the product
can not be put ON,
it ensures a safe
condition
If the device or its
electrical connec-
tions breaks down,
the machine ope-
ration is blocked.
If the machine is
constantly blocked
as a result of the
flue gas safety de-
vice, it is necessa-
