Safety Regulations - Riello RL 28 Manuel D'entretien

THE BURNER ROOM
• The burner room's external air openings must conform to the norms
prevailing locally. When in doubt regarding air circulation, we recom-
mend first measuring the CO
maximum delivery and the room ventilated only by the burner ventila-
tion air openings and then measuring the CO
with the door open. The CO

differ. Should there be more than one burner and fan in the same
room, this test must be performed with all the equipment operating si-
multaneously.
• Never obstruct the burner room's air openings, the burner fan suction
opening, and any air ducts and ventilation grates existing in order to
avoid:
- the build-up of toxic/explosive gas mixes in the burner room air;
- combustion with insufficient air, resulting in dangerous, expensive,
and polluting operation.
• The burner must always be protected against rain, snow, and freezing
conditions.
• The burner room must be kept clean and free of volatile substances
that may be sucked into the fan and clog the inner burner or combus-
tion head air ducts. Dust is also extremely harmful, especially if it is
allowed to build up on the fan blades where it will reduce ventilation
and produce pollution during combustion. Dust can also accumulate
on the rear part of the flame stability disk in the combustion head and
cause a poor air-fuel mixture.
FUEL
• The burner must be fed with the type of fuel for which it has been pre-
set as indicated on the rating plate and in the technical specifications
provided in this Manual.
• The fuel pressure at the entry to the pump must not exceed the value
listed in this Manual.
• The fuel line that feeds the burner must be perfectly sealed in order to
prevent air from entering the pump, and must be sized according to
the distance and the height differences present in the system as re-
quired by this Manual. The fuel supply line must also be equipped with
all the control and safety mechanisms required by local regulations in
force. The line should preferably be in copper and be free from all im-
purities; take particular care that foreign matter does not enter the line
during installation.
• The light oil storage tank must be adequately protected against pen-
etration of impurities and water. The fuel tank must be kept full of fuel
during the summer in order to avoid the condensation of humidity.
• Clean the tank carefully before filling with fuel.
• Both the tank and the burner fuel supply line must be protected from
frost.
• The light oil tank must be positioned in conformity with existing regu-
lations.
ELECTRICAL INPUT
• Make sure that the electrical power supply used for connection con-
forms to the specifications indicated on the rating plate and in this
Manual.
• The burner must be correctly connected to an efficient ground system
in conformity to the prevailing norms and checked and controlled for
efficiency by qualified personnel when in doubt.
• Never confuse neutral wires with phase wires.
• The burner can be hooked up to the electrical network with a plug-
socket connection only provided that the configuration of the coupling
is such as to prevent inversion of phase and neutral. Install a master
switch for the heating plant as requested by existing legislation.
• The entire electrical system, and all cable sections in particular, must
be adequate to deliver the maximum absorbed power value indicated
on the equipment's rating plate and in this Manual.
• If the mains power cable is found to be defective, it must be replaced
only by qualified personnel.
• Never touch the burner with wet parts of the body or without wearing
shoes.
• Never stretch power supply cables and keep them well away from
sources of heat.
• The length of the cables used must permit the opening of the burner
and the boiler door.
• Electrical connections must be made exclusively by qualified person-
nel and all prevailing electrical regulations must be scrupulously ob-
served.
PACKAGING
• After removing all packaging materials, check the contents to make
sure that no damage has occurred during shipping. When in doubt, do
not use the burner and contact the supplier.
• The packaging materials (wooden crates, plastic bags, plastic foam,
clips, etc.) are a source of pollution and potential hazard if left lying
around; collect them together and dispose of them properly.

THE BURNER
• Never permit children or unauthorized persons to tamper with the
burner.
• The burner must be used only for its expressed applications. The
burner may be used with water, steam, and diathermic oil boilers, and
in all the other applications expressly provided for by the manufactur-
er. All other uses are considered dangerous.
The burner's minimum and maximum delivery settings, the combus-
tion chamber pressure and its size, and the surrounding temperature
must all be contained in the range stipulated in this Manual.
• Use only original spare parts when equipping the burner with option-
als, kits, or accessories.
• Modification of the equipment in order to alter its performance or ap-
plication is prohibited.
• Do not open or tamper with components of the burner other than
those parts of the unit that are subject to maintenance operations.
• Only parts indicated by the manufacturer in the Spare Parts Cata-
logue may be replaced.
• Never touch the hot parts of the burner; these parts, usually located
near the flame, heat up during operation and may remain hot for quite
some time after the burner has switched off.
• When the burner is not to be used for a certain period, the main power
switch on the electrical control panel must be switched off and the
manual valve on the burner fuel supply line must be closed. When the
burner is no longer required for use, the following operations must be
performed:
- the electrical power cable must be disconnected from the main pow-
er switch by qualified personnel;
- the manual valve on the burner fuel supply line must be closed and
the command handwheel must be locked in place or removed.
BURNER INSTALLATION AND SETTING
• The installation and calibration of the burner must be performed ex-
clusively by qualified personnel in conformity with existing regulations
and the indications provided in this Manual.
• The burner must be secured tightly to the boiler in such way that the
flame is generated only inside the combustion chamber.
• Before firing the burner, obtain permission from the person in charge
of the boiler room to make sure that the boiler has been filled with wa-
ter or diathermic oil, that the water circuit valves are open, and that
the flue gas stacks have been suitably sized and freed from all ob-
struction. Then perform the following operations:
- Set the fuel delivery according to the power required by the boiler
within the burner's firing rates range as listed in this Manual.
- Adjust the combustion air delivery, the combustion head, and the
pressure of the fuel at the nozzle.
- Make sure that the combustion chamber pressure conforms to the
value provided by the boiler manufacturer.
- Analyze the flue gas to make sure that pollutant values do not ex-
ceed the limits established by law.
- Check the efficiency of the safety and adjustment mechanisms.
- Check the efficiency of the flue gas exhaust duct.
- Make sure that all mechanical fixings on the adjustment mecha-
nisms are sufficiently tight before leaving the plant.
BURNER MALFUNCTION
• If the burner stops working and goes into lock-out and does not
resume operation after two or three manual lock-out reset attempts,
contact a qualified specialist.
• If the burner breaks down and/or malfunctions, disconnect the power
supply, do not attempt to repair, and contact a qualified specialist.
All burner repairs required must be performed exclusively at a techni-
cal servicing centre authorized by the manufacturer using original
spare parts only.
Failure to observe the above may compromise the reliability and safe-
ty of the equipment.
MAINTENANCE
• Burner maintenance must be performed by qualified personnel regu-
larly or at least once a year according to the indications given in this
Manual.
• Prior to performing any burner maintenance operations, switch off the
power supply by using the main switch and cut off the fuel supply as
well.
