2.3 FIRING RATE
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 diagram EN 676.
For applications where the boiler does not conform to EN 303, or where the combustion chamber is much
smaller than the dimensions 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 10.5 mbar, 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
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.
The installation of the burner must be carried out by qualified personnel, as indicated in this manual
and in compliance with the standards and regulations of the laws in force.

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:
the 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 carefully and carry out a good earth connection.
The section of the conductors must be at least 1mm².
(Unless requested otherwise by local standards and legisla-
tion).
The electrical wiring carried out by the installer must be in
compliance with the rules in force in the country.
TESTING
Check the shut-down of the burner by opening the thermostats,
and the lock-out by opening the connector (CN3) inserted in the
red cable of the probe placed outside of the control box.
NOTES
The burners have been type-approved for intermittent opera-
tion. 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 ensures 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).
