FOREWORD
2) SPECIAL INSTRUCTIONS FOR BURNERS
*The burner should be installed in a suitable room, with
ventilation openings complying with the requirements of the
regulations in force, and sufficient for good combustion.
* Only burners designed according to the regulations in force
should be used.
* This burner should be employed exclusively for the use for
which it was designed.
* Before connecting the burner, make sure that the unit rating
is the same as delivery mains (electricity, gas oil, or other fuel).
*Observe caution with hot burner components. These are,
usually, near to the flame and the fuel pre-heating system,
they become hot during the unit operation and will remain hot
for some time after the burner has stopped.
* When the decision is made to discontinue the use of the
burner, the user shall have qualified personnel carry out the
following operations:
a) Remove the power supply by disconnecting the power cord
from the mains.
b) Disconnect the fuel supply by means of the hand-operated
shut-off valve and remove the control handwheels from their
spindles.
Special warnings
* Make sure that the burner has, on installation, been firmly
secured to the appliance, so that the flame is generated inside
the appliance firebox.
* Before the burner is started and, thereafter, at least once a
year, have qualified personnel perform the following
operations:
a) set the burner fuel flow rate depending on the heat input of
the appliance;
b) set the flow rate of the combustion-supporting air to obtain a
combustion efficiency level at least equal to the lower level
required by the regulations in force;
c) check the unit operation for proper combustion, to avoid any
harmful or polluting unburnt gases in excess of the limits
permitted by the regulations in force;
d) make sure that control and safety devices are operating
properly;
e) make sure that exhaust ducts intended to discharge the
products of combustion are operating properly;
f) on completion of setting and adjustment operations, make
sure that all mechanical locking devices of controls have been
duly tightened;
g) make sure that a copy of the burner use and maintenance
instructions is available in the boiler room.
* In case of repeated burner shut-downs, do not continue re-
setting the unit manually. Contact qualified personnel to take
care of such defects.
* The unit shall be operated and serviced by qualified
personnel only, in compliance with the regulations in force.
1) GENERAL INTRODUCTION
The equipment must be installed in compliance with the
regulations in force, following the manufacturer’s instructions,
by qualified personnel.
Qualified personnel means those having technical knowledge
in the field of components for civil or industrial heating
systems, sanitary hot water generation and particularly
service centres authorised by the manufacturer.
Improper installation may cause injury to people and animals,
or damage to property, for which the manufacturer cannot be
held liable.
* Remove all packaging material and inspect the equipment
for integrity.
In case of any doubt, do not use the unit - contact the supplier.
The packaging materials (wooden crate, nails, fastening
devices, plastic bags, foamed polystyrene, etc), should not be
left within the reach of children, as they may prove harmful.
* Before any cleaning or servicing operation, disconnect the
unit from the mains by turning the master switch OFF, and/or
through the cut-out devices that are provided.
* Make sure that inlet or exhaust grilles are unobstructed.
* In case of breakdown and/or defective unit operation,
disconnect the unit. Make no attempt to repair the unit or take
any direct action.
Contact qualified personnel only.
Units shall be repaired exclusively by a servicing centre, duly
authorised by the manufacturer, with original spare parts.
Failure to comply with the above instructions is likely to impair
the unit’s safety.
To ensure equipment efficiency and proper operation, it is
essential that maintenance operations are performed by
qualified personnel at regular intervals, following the
manufacturer’s instructions.
* When a decision is made to discontinue the use of the
equipment, those parts likely to constitute sources of danger
shall be made harmless.
* In case the equipment is to be sold or transferred to another
user, or in case the original user should move and leave the
unit behind, make sure that these instructions accompany the
equipment at all times so that they can be consulted by the
new owner and/or the installer.
* For all the units that have been modified or have options
fitted then original accessory equipment only shall be used.
* This unit shall be employed exclusively for the use for which
it is meant. Any other use shall be considered as improper
and, therefore, dangerous.
The manufacturer shall not be held liable, by agreement or
otherwise, for damages resulting from improper installation,
use and failure to comply with the instructions supplied by the
manufacturer.
