Important
In case of gas smell:
1 - do not press electrical switches, use the telephone or other objects that can provoke
sparks;
2 - open immediately the windows and the doors in order to cleanse the room air;
3 - close the gas supply taps;
4 - call a qualified technician.
Do not obstruct the ventilation openings
of the gas boiler room, in order to avoid possible
dangerous situations as the creation of poisonous or explosive mixtures.
First starting up and Use
The first starting up and the maintenance of the boiler must be performed by a professionally
qualified staff (for example the installer or the Service Centres authorized by ITALTHERM)
Gas conversion from a gas of a specific family to a gas of another family (from natural gas to LPG or vice
versa) to another gas, can be made also when the gas boiler is already installed, but only by a qualified
technician. The technician will check that:
f
the label technical data of the gas boiler correspond to those of the gas available;
f
the main burner regulation is compatible with the gas boiler output;
f
the chimney works correctly, expelling the combustion products;
f
the air supply and the combustion products evacuation work correctly, in accordance with the re-
quirements in force;
f
the conditions for a correct ventilation are guaranteed, also when the gas boiler is located inside a
closed space (with suitable characteristics).
The User must not touch sealed items nor break the seals. Only specialized technicians and the
official technical service can break the seals of sealed items.
The boiler is fitted with a safety flue flow detection device that should never be bypassed or put
out of order. If the pressure switch must be replaced, use the original spare part only. In case of
repeated interventions of the device (and consequent boiler locks), check that the Flue Products
Outlet System is efficient and made according to the laws in force (see examples in paragraph
"Chimney connections" on page 18) and that the air supply and room ventilation system is efficient
and made according to the laws in force .
When the boiler is off for a long period see the Paragraph "Boiler inactivity" on page 11 for the
necessary precautions about the electrical supply, the gas supply and the protection against
freezing.
Do not touch the heated surfaces
of the boiler, as the doors, the flue, the chimney pipe, etc.,
also after the boiler operation because, for a certain time, these surfaces are overheated.
Any
contact with them can cause dangerous scalds.
It is then forbidden to let children or inexperi-
enced people be close to the boiler, during its operation.
f
Do not expose the wall hung gas boiler to water or other liquids sprinklings, or to vapours directly
coming from gas cookers/hobs.
f
Do not obstruct the air inlet or flue outlet terminals, even momentarily or partially.
