BIASI B/40
PAGE 10
Good, reliable operation with a minimum of service starts with attention to the small details:
1. Setting the nozzle position and electrodes "by the book" using the manufacturer's gauges.
2. Installing a quality micron filter at the burner.
3. Making careful/tight flare connections without couplings on oil suction line.
4. Checking fuel pump pressure.
5. Checking draft at the breeching to insure it is adequate to overcome flue gas resistance.
6. Setting the air band properly with well maintained instruments. A good target is 11% to 12.5% of (CO
2
) or 6.5%
to 3.8% of (O
2
).
Note: Oil and Gas burners on B40-series boilers cannot be properly commissioned
without instruments and gauges.
The following information applies only to the BIASI B-40 series boilers at a maximum output
for power venters or lined chimneys only.
