Special instructions for using gas.
• Check that the feed line and the train comply with current standards
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 away for some time, close the main gas feed valve
to the burner.
• If you smell gas:
- do not operate electrical switches, the phone or any other
object that can cause sparks;
- immediately open 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 block ventilation openings in the room where there is gas
equipment or dangerous situations may arise with the build up of
toxic and explosive mixtures.
RESIDUAL RISKS
• In spite of the accurate product planning according to the regulations
in force, residual risks may still be present during correct use. They
are indicated on the burner by means of specific Pictograms.
CAUTION
Mechanical parts in motion.
CAUTION
Materials at high temperatures.
CAUTION
Energised electrical switchboard
INSTRUCTIONS ON ELECTRICAL SAFETY
• Check that the equipment is properly grounded according to the
safety standards in force.
• Do not use the gas pipes to ground electrical equipment.
• If in doubt, call for a careful electrical check by a qualified technician,
since the manufacturer will not be liable for any damage caused by
a poor ground connection.
• A professional check should be carried out to ensure that the
electrical installation is adequate for the maximum output absorbed
by the system. This is indicated on the data plate.
• Make sure that the system cable cross-section is suitable for the
power absorbed by the equipment.
• The use of adaptors, multiple plugs and/or extension leads to
supply power from the mains to the appliance is not allowed.
• For the connection to the mains, fit an omnipolar switch with a
contact opening gap equal to or greater than 3 mm in accordance
with current safety regulations (Overvoltage category III).
• Use only double insulated cables with external thickness of at least
1mm for the power supply of the burner.
• Unsheathe the external insulating cover of the power cable to the
necessary extent for the connection, thus avoiding the wire from
coming into contact with metal parts.
• The electrical supply to the burner must have neutral to ground
connection. In the case of a ionisation current check with neutral
not to ground, it is essential to make a connection between terminal
2 (neutral) and the ground for the RC circuit.
• If the user is away for some time, close the main gas feed valve
to the burner.
• The use of any components that use electricity means that certain
fundamental rules have to followed, including the following:
- do not touch the equipment with parts of the body that are wet
or damp and/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 express provision for
this.
- do not allow the equipment to be used by children or
inexperienced persons.
- The power supply cable for the equipment not must be replaced
by the user. If the cable is damaged, turn off the equipment. To
replace the cable, contact exclusively qualified personnel.
- If you decide not to use the equipment for a while it is advisable
to switch off the electrical power supply to all components in the
system that use electricity (pumps, burner, etc.).
• Use flexible cables compliant with standard EN60335-1:
- if PVC sheathed at least H05VV-F
- if rubber sheathed at least H05RR-F
- if unsheathed at least FG7 or FROR
