SPECIAL PRECAUTIONS WHEN USING GAS.
• Check that the feed line and the train comply with current law and
regulations.
• Check that all the gas connections are properly sealed.
• Do not leave the equipment on when it is not in use and always close
the gas cock.
• If the user is absent for a prolonged period of time, close the main
gas feed tap to the burner.
• If you smell gas:
- do not operate electrical switches, phones or any other object
that may cause sparks;
- open immediately doors and windows to create a draught to
clear the air in the room;
- close the gas cocks;
- have professionally qualified personnel correct the fault.
• Do not obstruct ventilation openings in the room where there is gas
equipment. Otherwise, dangerous situations may arise with the build
up of toxic and explosive mixtures.
• If the user is absent for a prolonged period of time, close the main
gas feed tap to the burner.
RESIDUAL RISKS
• Even though the product was designed in compliance with the obli -
gatory standards, residual risks may still be present during correct
operation. They are signalled on the burner through special Picto -
grams.
CAUTION
Moving mechanical organs.
CAUTION
Materials at high temperature.
CAUTION
Powered electric panel.
ELECTRIC SAFETY WARNINGS
• Check that the equipment has a suitable ground system, carried out
following safety standards in force.
• Have qualified personnel check that the electric system is adequate
to equipment maximum power consumption indicated on the plate.
• For the mains supply connection is required an omnipolar switch
with a contact opening gap equal or above 3 mm in accordance with
current safety regulations (condition of overvoltage category III).
• Remove the external insulating seal of the supply pipe necessary for
the connection, preventing the cable to touch metal parts.
• The use of any electrically fed components entails complying with
certain fundamental rules, including the following:
- do not touch the equipment with parts of the body that are wet or
damp or with damp feet;
- do not pull on electrical cables;
- do not leave the equipment exposed to atmospheric agents
(such as rain or sun etc.) unless there is explicit provision for
this;
- do not allow the equipment to be used by children or inexpert
persons;
- The power supply cable for the equipment must not be replaced
by the user. In case of cable damage, turn the equipment off. To
replace it contact qualified personnel only;
- If you decide not to use the equipment for a certain period of time
it is advisable to switch off the electrical power supply to all com -
ponents in the system that use electricity (pumps, burner, etc.).
• Use regulation-compliant flexible cables EN60335-1:EN 60204-1
- in case of PVC sheath, at least type H05VV-F;
- in case of rubber sheath, at least type H05RR-F; LiYCY
450/750V
- without any sheath, at least type FG7 o FROR, FG70H2R
• The electric equipment works correctly at altitudes of up to 1000 m
above the see level.
TO BE CARRIED OUT BY THE INSTALLER
• Install a suitable circuit breaker for each power supply line of the bur -
ner, according to the characteristics and the diagram on the chapter
ELECTRICAL CONNECTIONS.
• The disconnection must be carried out by means of a device com -
plying with the following requirements:
- A disconnecting switch - circuit breaker, according to IEC 60947-
3 for at least the equipment category AC-23 B (non-frequent
operations on highly inductive loads or AC motors).
- A control and protection switching device suitable for isolation
according to IEC 60947-6-2.
- A switch suitable for isolation according to IEC 60947-2.
• The disconnecting device must:
- Ensure the isolation of the electrical equipment from the power
supply line when in the stable OFF position indicated with “0”,
and be in a stable ON position indicated with “1”.
- Feature a visible gap between contacts or a position indicator
that cannot indicate OFF (isolated) until all contacts are actually
open and the requirements for the isolation function are met.
- Feature a grey or black actuator which can be easily identified.
- Be padlockable in the OFF position. In case of lock-out, remote
and local activation will not be possible.
- Disconnect all the active conductors of its power supply circuit.
For TN power supply systems, the neutral conductor can be
disconnected or not, except in the countries where the discon -
nection of the neutral conductor (if used) is mandatory.
• Both disconnecting controls must be located at a height between 0,6
m ÷ 1, 7 m with respect to the working plane.
• Since circuit breakers are not emergency devices, they can feature
an additional cover or a door, which can be easily opened without
any key or tool. Its function must be clearly indicated, e.g. with the
relevant symbols.
• The burner can be installed only in TN or TT systems. It cannot be
installed in isolated system of IT type.
