START-UP
Select the gas operation in order to proceed with start up on the gas side. On the selector put the operation on minimum capacity.
!
KMV contactor: check the air fan motor rotation.
If not correct invert the two phases on the power supply.
Adjusting the maximum air flow rate

START UP THE BURNER
The control box starts the pre-purge cycle, the fan motor and opens the air flaps in full open position.
After a few seconds the control box opens the gas valves and starts the flame.
At the end of pre-purging, the control box drives the servomotor into the ignition position and starts the ignition transformer.
After the flame stabilisation the burner goes in the low flame.
In case of faulty ignition, the control box switches the burner into safety condition, in such a case you must rearm the burner.
Gradually go step by step using the selector on position 0 to stop the flame, from the low flame to the high flame in order to have a
stable flame.
The flame stabilisation can be achieved by adjusting the gas flow on the gas train (REFER TO THE GAS TRAIN MANUAL)
When the servomotor arrive at 90° you have the fine tune the air and gas flow according to the boiler capacity required.
Check the combustion values throughout the adjusting.
Firing head setting
Servomotor SQM50 - Air damper motor pre-setting
The cams of the servomotor are set from the factory in order to start the burner and reach the
maximum output.
The following setting are the standard one:
I. High flame position 90°
II. Air flap position in standby 0°
III. Ignition position gas 10°
IV. Low flame position gas 15° (can be modified depending on the minimum output of the boiler)

In order to adjust the maximum air flow rate see figure with
selector in maximum operation. Loosen the nut holding the air
damper transmission rod and correct air flow till you reach
the combustion values suggested by reading the value on the
combustion analyser. If you do not reach acceptable air flow
rate you shall adjust the firing head. Move the head forward to
increase air flow backwards to reduce.

The firing head is pre-adjusted at the 50% from the factory. The
setting fully open enables to reach the full power of the burner
and full close to reach the minimum power of the burner.
The optimal position depends on the output that we need to
reach but the default setting shall be modified only when you are
not able to reach the suggested combustion value by adjusting
the air flow in the maximum flame.
