1.2 ACCESSORIES
SOFTWARE DIAGNOSTIC KIT
A special kit is available that, by an optical link to a PC, shows the burner life together with operating hours, type
and number of failures, serial number, etc.
To visualise the diagnostics proceed as follows:
Connect the kit supplied separately to the control box socket.
Reading of the information begins when the software programme included in the kit starts.
REMOTE RESET KIT
The burner has a remote reset kit (RS) consisting of a connection and a push-button operating at a dis-
tance of 20 metres max. In order to install it remove the protective lock-out installed at the factory and
insert the lock-out supplied with the burner (see electrical diagram on page 8).
MULTIBLOC ROTATION KIT
There is a special kit available that can be used to install the burner turned 180°, as illustrated on page 5 in
position 5 in the section entitled "3.1 WORKING POSITION". This kit is designed to ensure the gas train
valve works properly. The kit must be installed in conformity with laws and local regulations.

2.3 FIRING RATES
In the BS4D model type 918T1, in order to guarantee the working
with an output of 220 - 250 kW, remove the blank deadening to free the
supplementary slits of the air inlet on the cover.
TEST BOILER
The firing rate has been defined according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler conforms to EN 303 and
the combustion chamber dimensions are similar to those shown in the dia-
gram EN 676. For applications where the boiler does not conform to
EN 303, or where the combustion chamber is much smaller than the dimen-
sions given in EN 676, please consult the manufacturers.

CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 9.3 mbar, relatively to 916T1 model, is measured
(M2, see chapter 3.6, page 7) with the combustion chamber at 0 mbar using gas G20 with a net heat value
of 10 kWh/m3(8.570 kcal/m3).
3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.
3.1 WORKING POSITION
The burner is designed for operation in position 1only.
Installation in positions 2, 3, 5, 6 and 7is not recommended as it is likely to hinder the unit’s proper operation
since air damper closure cannot be guaranteed when the burner is on standby.
Installation in position 5is only possible using the “MULTIBLOC rotation kit”, to be ordered separately.
Installation 4is prohibited as safety is compromised.

3.2 BOILER FIXING
To fit the burner to the boiler it is necessary to carry out the following:
Widen, if necessary, the insulating gasket holes (3, fig. 3).
Fix the flange (5) to the boiler door (1) using four screws (4) and (if necessary) the nuts (2) interposing
the insulating gasket (3) but keep unloosing one of the two upper screws (4) (see fig. 2).
Put on the flange (5) the burner combustion head, tighten the flange with the screws (6) and lock the
loose screw (4).
N.B.: The burner can be fixed with the variable dimension (A) (see fig. 4). Anyway, make sure that the
combustion head crosses completely the boiler door thickness.

3.4 GAS TRAIN, (as EN 676)
The gas train is supplied separately, for its adjustment see the enclosed instructions.
3.5 GAS TRAIN ELECTRICITY SUPPLY
The gas train’s power cables can be fed to the right or
left of the burner, as illustrated in figure 6.
Depending on the entry point, the cable clamp with
pressure test point (1) and simple cable clamp (2) may
need swapping over.
Consequently, you must make sure:
cable clamp (1) is positioned correctly;
the tube is positioned correctly so that there are no
restrictions likely to impede air flowing to the pres-
sure switch.
WARNING
If necessary, cut the tube to the right size.

ATTENTION:
Do not swap neutral and phase over, follow the diagram shown care-
fully and carry out a good earth connection.
The section of the conductors must be at least 1mm2. (Unless requested
otherwise by local standards and legislation).
The electrical wiring carried out by the installer must be in compliance
with the rules in force in the country
Connect the 2nd stage thermostat (TR) to terminals T6 - T8 and remove
the bridge.
TESTING
Check the burner has stopped by opening the thermostats.
Check that the burner is blocked by opening the connector (CN1) inserted
in the probe red wire and located outside the control box.
CONTROL BOX, (see fig. 8)
To remove the control box from the burner it is necessary to:
disconnect all the connectors, the 7-pin plug, the high voltage cables and the
earth wire (TB);
unscrew the bolt (A, fig. 8) and pull the control box in the direction of the arrow.
To install the control box it is necessary to:
screw the bolt (A) in at a torque of 1 - 1.2 Nm;
reconnect all the connectors previously disconnected.
NOTES
The burners have been type-approved for intermittent operation. This means they
must stop at least once every 24 hours in order to allow the electrical control box
to check its efficiency on start-up. The boiler limit thermostat (TL) normally en-
sures the burner halts. If this does not happen a time switch halting the burner at
least once every 24 hours must be applied in series to limit thermostat (TL).
