The pump is adjusted during testing and inspection to 12 bar. VERIFY: - That piping system is perfectly sealed; - That the use
of hoses is avoided whenever is possible (use copper pipes preferably); - That depression is not greater than 0,45 bar, to avoid
pump’s cavitation; - That check valve is suitably designed for the duty; The pump pressure is set at a value of 12 bar during the
testing of burners. Before starting the burner, bleed the air in the pump through the gauge port. Fill the piping with light-oil to
facilitate the pump priming. Start the burner and check the pump feeding pressure. In case the pump priming does not take place
during the first prepurging, with a consequent, subsequent lock-out of the burner, rearm the burner’s lock-out to restart, by
pushing the button on the control box. If, after a successful pump priming, the burner locks-out after the prepurging, due to a fuel
pressure drop in the pump, rearm the burner’s lock-out to restart the burner. Do not allow the pump to work without oil for more
than three minutes. NOTE: Before starting the burner, check that the return pipe is open. An eventual obstruction could
damage the pump sealing device.

Adjust light-oil pressure and airflow for the low flame.
The burner will operate in Low flame until the switch set again
to High flame. The control box will then enable the High
flame, through the full opening of the air damper.
The High flame pressure, in normal operation, must be set to
12-15 bar (check on the manometer connected to the pressure
port). Adjust the combustion air through the head adjusting
lever.
