Start-up, calibration and operation of the burner

6.3

Servomotor adjustment

The servomotor provides simultaneous adjustment of the air
damper, by means of the variable profile cam and the gas
butterfly valve. The servomotor rotates by 130° in 42 s.

6.4

Burner start-up 

Feed electricity to the burner via the disconnecting switch on the
boiler panel.
Close the thermostats/pressure switches and turn the switch in
Fig. 31 to position “

MAN

”.

As soon as burner starts, check the fan rotation direction
through the flame inspection window.

6.5

Burner ignition

If the motor starts up, but the flame does not appear and the
control box goes into lockout, reset it and wait for a new
ignition attempt.
If ignition is still not achieved, it may be that gas is not
reaching the combustion head within the safety time period of
3 seconds. In this case, increase gas ignition delivery.
The arrival of gas to the sleeve is indicated by the U-type
pressure gauge (Fig. 29 on page 29).
Once ignition has taken place, proceed with burner global
calibration operations.

ATTENTION

Do not alter the factory setting for the 5 cams;
just check that they are as specified below:

Cam I:

130°

.

 

Limits rotation toward maximum 

position. When the burner is operating at 
MAX output, the gas butterfly valve must be 
fully open: 90°.

Cam II:

. Limits rotation toward minimum position. 

When the burner is shut down, the air 
damper and gas butterfly valve must be 
closed: 0°.

Cam III:

30°

. Adjusts the ignition position and the MIN 

output. 

Cams IV and V:

Not used.

Fig. 30

D887

DANGER

Check that the lamps or the testers connected to the
solenoid valves or the pilot lights on the solenoid
valves indicate that no voltage is present. 
If they indicate the presence of voltage, stop the
burner 

immediately

 and check the electric

connections.
