ARTÙ 2
Air circulation
It is vital that areas where gas devices are installed (type B) have
access to the amount of air necessary for the regular combustion
of gas as well as the ventilation of the venue.
- It is prohibited to use an extractor fan, fireplaces and other similar
devices at the same time as the water heater.
- The area where the water heater is installed must have a regular
flow of air for ventilation.
Air flow
The flow of air must occur by the following means:
- permanent openings in the wall that lead outdoors;
- single or collective ventilation ducts.
The air used for ventilation must be taken directly from an outside
location, that is far from sources of pollution.
Indirect ventilation from adjacent areas are permitted with the
following limitations:
- the adjacent area is equipped with direct ventilation;
- the devices within the area to ventilate are connected to a waste
duct;
- the adjacent area does not contain a bedroom and is not a
common area;
- the adjacent area is not a fire hazard such as a storage area for
flammable materials, garage etc.;
- the adjacent area is not lower than the area to ventilate as this
might lead to an opposing draught (this can be caused by other
devices that operate on the basis of combustion, a fireplace or any
suction device that have not been given an adequate air supply);
- the air flow from the adjacent area occurs freely through
permanent openings.
2.d Electrical connection to battery
The device is powered by two 1,5 V batteries (D-Type model) alkaline
long lasting model, thus it is not necessary to connect the device to a
power socket.

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;

12 NTC probe
- 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
maximum 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.
Remove the protective caps from the inlet and outlet water
connection.
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 B water heater is supplied with a device for releasing flue
11BS
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 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
byproducts; the flow of combustible gas to the release conduit and
the smoke channel.
The safety device contains a "thermostat" connected to the
electronic 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.
