GAS CONNECTION

The gas intake pipe must be connected to the boiler using the respective
G 3" fitting as indicated in parag. 2.3.
The supply pipe must have a section equal to or
in the boiler and must nevertheless provide the correct gas pressure.
It is nevertheless advisable to adhere to the standard specifications
and requirements in force, setting up a cut-off valve, gas filter, anti-
vibration joint, etc.
Before commissioning an internal gas distribution system and therefore,
before connecting it to the meter, it is necessary to thoroughly check
the seal.
If any part of the system is not in view, the sealing test must be carried
out before covering the pipe.
Danger!
The gas connection must be set up by an authorised
installation technician who must observe and apply
the contents of the legislation in force and the local
requirements of the gas supply company, as incorrect
installation can cause damage to people, animals
and property, for which the manufacturer will not
be held liable.

Instructions for the installer
Before installation it is advisable to clean the inside
of the fuel intake pipe thoroughly, in order to remove
any residues that could stop the boiler from operating
smoothly.
If you notice the smell of gas:
a) Do not work the electrical switches, the telephone
or any other object that can generate sparks;
b) Immediately open doors and windows to create an
air current that purifies the room;
c) Close the gas valves;
d) Seek the assistance of professionally qualified
personnel.
In order to prevent any gas leaks it is advisable to install
a surveillance and protection system composed of a gas
leak detector combined with a cut-off electrovalve on
the fuel supply line.
