to take the maximum power used by the equipment shown on the equipment
rating plate. In particular, make sure that the system cable cross section is
adequate for the power absorbed by the unit.
* No adaptors, multiple outlet sockets and/or extension cables are permitted
to connect the unit to the electric mains.
An omnipolar switch shall be provided for connection to mains, as required
by the current safety regulations.
The use of any power-operated component implies observance of a few
basic rules, for example:
- do not touch the unit with wet or damp parts of the body and/or with
bare feet;
- do not pull electric cables;
- do not leave the equipment exposed to weather (rain, sun, etc.)
unless expressly required to do so;
- do not allow children or inexperienced persons to use equipment;
* The unit input cable shall not be replaced by the user.
In case of damage to the cable, switch off the unit and contact qualified
personnel to replace.
* When the unit is out of use for some time the electric switch supplying all
the power-driven components in the system (i.e. pumps, burner, etc.) should
be switched off.

3B FIRING WITH GAS, GASOIL OR OTHER FUELS
GENERAL
* The burner shall be installed by qualified personnel and in compiance with
regulations and provisions in force; wrong installation can cause injuries to
people and animals, or damage to property, for which the manufacturer cannot
be held liable.
* Before installation, it is recommended that all the fuel supply system pipes
be carefully cleaned inside, to remove foreign matter that might impair the
burner operation.
* Before the burner is commissioned, qualified personnel should inspect the
following:
a) the fuel supply system, for proper sealing and pressure soundness;
b) the fuel flow rate, to make sure that it has been set based on the
firing rate required of the burner;
c) the burner firing system, to make sure that it is supplied for the
designed fuel type;
d) the fuel supply pressure, to make sure that it is included in the range
shown on the rating plate;
e) the fuel supply system, to make sure that the system dimensions
are adequate to the burner firing rate, and that the system is
equippped with all the safety and control devices required by the
regulations in force.
* When the burner is to remain idle for some time, the fuel supply tap or taps
should be closed.
SPECIAL INSTRUCTIONS FOR USING GAS
* Have qualified personnel inspect the installation to ensure that:
a) the gas delivery line and train are in compliance with the regulations
and provisions in force;
b) all gas connections are tight;
c) the boiler room ventilation openings are such that they ensure the
air supply flow required by the currrent regulations, and in any case
are sufficient for proper combustion.
* Do not use gas pipes to earth electrical equipment.
* Never leave the burner connected when not in use. Always close the gas
valve.
* In case of prolonged absence of the user, the main gas delivery valve to
the burner should be closed.
PREFACES
Precautions if you can smell gas:
a) do not operate electric switches, the telephone, or any other item
likely to generate sparks;
b) immediately open doors and windows to create an air flow to purge
the room;
c) close the gas valves;
d) contact qualified personnel.
* Do not obstruct the ventilation openings of the room where gas appliances
are installed, to avoid dangerous conditions such as the development of
toxic or explosive mixtures.
