Checks to be made at first lighting, and after all maintenance operations involving disconnection from
the systems or work on safety devices or parts of the burner:
Before lighting the burner,
• Make sure the burner is correctly fixed in the boiler with the preliminary settings indicated above.
• Make sure the boiler and system are filled with water or diathermic oil, the plumbing circuit valves
are open and that the flue is free and correctly sized.
• Check closing of the boiler door, so that the flame is only generated inside the combustion
chamber.
• Check the correct positioning of the auger and the burner connection flexible tube.
• Fill the hopper with pellets.
Make sure the grille is clean (fig. 5).
Burner lighting

• To fill the auger with pellets, see par. 2.3.
• Close the thermostat line (boiler/room).

meanwhile, check the efficiency of the fume exhaust pipe.
2. MAKE SURE THE COMBUSTION CHAMBER IS IN NEGATIVE PRESSURE.
3. Check the combustion at max. burner power (adjusted according to boiler nominal power).
4. If the O % in the fumes is not between 5% and 9%, change the fan set point by modifying the relevant
