2.4 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) ow-

ing 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.

When the burner operates with only one, or two nozzles, the pressurizzation conditions are improved and no

problems arise.

3. HYDRAULIC SYSTEMS

Pay attention to do not overcome the max. depression of

0.45 bar (35 cm Hg), over this value the fuel may turn into gas.

Check the pipes are perfectly sealed.

When the fuel tank is under the burner level we suggest to

let the return line arrive where the suction line starts. In this

case the foot valve is not necessary.

Should the return line arrive over the fuel level, the foot

valve is indispensable. Notice that this solution is less safe

than the previous one, because it is possible the valve has

not a good sealing.

H= Difference in the pipes heights;

L= Total lenght of the suction tube;

øi= Internal diameter of the tube. Copper tubes øi14 mm

PUMP PRIMING:

Loose the tap from the vacuometer plug (5, fig.1)

and wait for the flow of the fuel.

max. 10 m

Before placing the burner in operation,

ensure that the return line is open. Any

obstruction may demage the pump seal.

ATTENTION:

max 10 m

PUMP PRIMING:

Fill the pump with the light oil

from the vacuometer plug

(5, fig.1), put the burner in

operation, purge the air from the

manometer plug (4, fig.1) and.

wait for the pump priming.

If lock-out occurs repeat the

SCHEMA (C) - Calibration of thermal relay

This is required to avoid motor burn-out in the

event of a significant increase in power

absorption caused by a missing phase.

• If the motor is star-powered, 400 V, the cursor

should be positioned to “MIN”.

• If it is delta-powered, 230 V, the cursor should

be positioned to “MAX”.

If the scale of the thermal relay does not include

rated motor absorption at 400 V, protection is

still ensured.

NOTE

In systems where the run of wiring connecting

the thermostat exceeds 20 metres in length, or

in places where the burner is subject to particu-

larly disturbing electromagnetic interference

(over 10 v/m), you must insert the relay-inter-

face kit item number 3010386.
