Commissioning
Commissioning the burner also involves
simultaneous installation by the fitter or
his representative; only they can
guarantee the boiler room complies with
currently accepted practices and
regulations in force.
Beforehand, the fitter must have
completely filled the suction line with fuel
oil, vented the primary filter and checked
that the manual quarter-turn and
protection valves function correctly.
Preliminary checks
• Check the available electric voltage
and compare it with the recommended
value.

If this pre-setting does not correspond to
the boiler power, follow the instructions

• Close the regulator circuit.
• Unlock the control unit.
• The burner is in service.
• Wait until the reheater thermostat has
closed (for burners with reheaters).
The burner starts up
• Carry out a combustion check: CO
opacity and exhaust gas temperature.
To increase the CO

• Reduce the air flap opening and vice
versa. Modifying its value may require
a correction of dimension Y, by turning
screw 3.
To modify the exhaust gas index
• Open the air flap to make it lighter, and
vice versa.
• Check the combustion parameters
under actual operating conditions
(doors closed, etc.), and test that the
various circuits are sealed.
• Record the results in the relevant
documents.
Safety checks
• Check, while the burner is functioning:
G1/8
- the opening of the regulator circuit,
G1/8
- the safety shutdown with lockout,
with no flame,
- the seal on the boiler front,
- the operation of the control devices
(if present),
- the vacuum pressure of the fuel
supply circuit, maximum 400 mbar
or 305 mm Hg.
