ROOMS VENTILATION
GAS APPLIANCES
This appliance is not connected to a device to vent the
combustion products. It must therefore be installed and
connected in conformity with the installation standards in
force. Particular attention must be paid to the standards
on ventilation of the room.
VENTILATION OF ROOMS
Remember that this appliance can be installed and work
in well-ventilated rooms only, according to the standards
in force, such as to allow, with openings on the external
walls or with special ducts, a correct natural or forced
ventilation ensuring permanently and sufficiently both
the entry of the air needed for correct combustion and
the removal of spent air.
In particular when there is only this gas appliance in the
room, there must be a hood over the appliance to ensu-
re the natural and direct removal of spent air, with a ver-
tical straight duct of length equal to at least twice the dia-
meter and a minimum section of at least 100 cm
2 .
For the indispensable entry of fresh air into the room the-
re must be a similar 100 cm
2 opening directly to the out-
side, situated at a height near floor level so that it is not
blocked either inside or outside the wall and so as not to
cause disturbances to correct burners combustion and to
the regular removal of spent air and with a difference of
height with respect to the outlet opening of at least 180
cm. Remember that the quantity of air necessary for
combustion must never be less than 2m
3 /h for each kW
of power (see total power in kW on the appliance data
plate). In all other cases, i.e. when there are other gas
appliances in the same room, or when natural direct ven-
tilation is not possible and natural indirect or forced ven-
tilation must be installed, contact a qualified specialist
who will install and make the ventilation system, scrupu-
lously observing the regulations contained in the stan-
dards in force.
The openings must be so positioned that there are no
draughts of air which cannot be tolerated by the occu-
pants.
Moreover to eliminate combustion products, it is forbid-
den to use flues already used by other appliances.
GAS CONNECTION
We recommend to check wether the appliance has been
foreseen for the kind of gas distributed.
The appliance must be connected to the gas piping in a
workmanlike way and in conformity with the regulations
in force which lay down the installation of a safety valve
at the end of the piping.
For butane and propane a pressure reducer conforming
to the standards in force may perform this task.

The sealgaskets must be i accordance with rules.
Once the gas appliance has been connected, check the
connected seal by means of soapy water.
The end of the attachment is threaded. The possible con-
nections are:
Fig. 12
- by rigid pipe in iron or copper
- by flexible tube in stainless steel with continuing wall,
with mechanical connection in accordance with rules.
The tube must be directly connected to the manifold
elbow (see Fig.10).
- by the insertion of a rubber tube in accordance with rules.
- This tube must be connected directly on the push-on
connector, concerning the gas used, and it must be
blocked with a band.In the last case, check the tube's
printed date of expiry and replace it before this date.
WARNINGS
Concerning rubber flexible tubes (max. length 1500 mm),
we remember you:
1 - to avoid the tube to be narrowed or crushed
2 - do not submit it to traction or torsion efforts
3 - to avoid contact with sharp edges, etc...
4 - to avoid contact with parts reaching temperatures
over 70°C the ambient temperature
5 - to ensure that they can be checked for all
their length.
