COMBUSTION CHAMBER PRESSURE - MAXIMUM OUTPUT
(Three nozzles in operation)
Operation field: Limit Safety
When the burner operates with only one or two nozzles, the pressurization conditions are improved and no
problems arise.
Boiler front plate drilling
Combustion head projection
For the combustion head projection carefully follow the boiler
manufacturer indications.
A proper protection with refractory material on the combustion head
projecting into the combustion chamber shall be made, when boilers
with frontal smoke box are used.

OPERATION AND EFFICIENCY OF THE BURNER
ACCESSOIRES
RADIO DISTURBANCE PROTECTION KIT: Code 3010386
If the burner is installed in places particularly subject to radio disturbance (emission of signals exceeding 10 V/m) owing
to the presence of an INVERTER, or in applications where the length of the thermostat connections exceeds 20 metres,
a protection kit is available as an interface between the control box and the burner.

HEAVY OIL SUPPLY LINE
RING SUPPLY LINE
(for heavy oil with viscosity up to 50°E at 50°C)
1- Tank (heated for heavy oil)
2- Filter (with resistance for oil > 7°E at 50°C)
3- Forwarding pump
4- Control manometer
5- Shutter valves (in couple) excluding the burner
6- Burner (provided for Kit for heavy oil code no. 3000721)
7- Pressure adjuster
8- Filter (with resistance for oil > 7°E at 50°C)
9- Burner pump
WARNING
- The oil could easily flow through the pipes if those are properly seized, protected and heated (by electricity, steam
or hot water).
- The forwarding pump capacity should be at the least double of that of the burner pump.
- If several burners are supplied through the same ring supply line, the forwarding pump should have a capacity of
approx. 30% more than the sum of the single burners outputs.
- For starting-up: after excluding the burner by the shutter valves (5) let the oil flow into the supply ring up to reach
the required circulation; after than open the valves and supply normally the burner.
GRAVITY SUPPLY LINE
(only for oil with max. viscosity up to 7°E at 50°C)
Notice: before placing the burner in operation, ensure that the return line is open. Any obstruction may damage the
pump seal.

NOTE:
yCheck the lock-out by darkening the photo-cell after removal of the cover.
ATTENTION HIGH VOLTAGE.
yIn case of supply 220V without neutral, connect the motor and the pre-heater thank through delta (the “star”
connection is the original one, made for 380V).
yNOTE
In systems where the run of wiring connecting the thermostat exceeds 20 metres in length, or in places where
the burner is subject to particularly disturbing electromagnetic interference (over 10 v/m), you must insert the
relay-interface kit item number 3010386.

CHOICE: OF THE NOZZLES - OF THE PUMP PRESSURE -
OF THE COMBUSTION HEAD ADJUSTMENT
• First of all state the maximum output required with all three nozzles in operation.
• On the base of the maximum output choose, from table A, three related nozzles.
Nozzles: 60° - Pump pressure: 25 bar.
• The references of table B should be followed in case of need of:
- modification of the pump pressure in order to vary the output,
- diverse composition of the 3 nozzles group,
- knowledge of the output in 1st and 2nd stage.
SUGGESTED NOZZLES
The pump pressure is referred to all three nozzles operating. The pump pressure increases automatically when two
nozzles are operating and becomes higher with only one nozzle.
