Final Burner Adjustments:
Final burner adjustments
must be made using combustion test instruments. Refer to
“Burner Settings”. Set burner accordingly.
• Check draft over fi re to verify it is between -0.01” WC
and -0.02” WC, adjust draft as necessary.
• After operating 10 minutes to warm up boiler, use
combustion test equipment to take smoke reading in
fl ue pipe between boiler and draft regulator.
• Smoke reading should be zero to trace (Shell Bacharach
Scale).
• A new boiler requires more than 10 minutes to burn
clean due to oil fi lm on new heat exchanger.
• If smoke reading is zero, gradually close burner’s air
adjustment to obtain smoke reading showing trace
smoke reading. Once smoke reading is trace, measure
CO
2
and as insurance margin increase air to suf fi ciently
reduce CO
2
by ½% to 1%.
If clean fi re cannot be obtained, it is necessary to
verify burner head and electrode alignment. Proper
electrode alignment fi gures are presented on following pages.
If fi re continues to be smoky, replace nozzle with correct
replacement.
Once burner is completely adjusted, burner should be
started and stopped several times to assure good operation
with no fl uttering or rumbling. Verify there are no oil leaks
and record nozzle size, oil pressure, combustion readings,
and air settings on tag or label attached to burner or, boiler.

BECKETT OIL BURNER SPECIFICATIONS
Oil Burner Maintenance
: For Beckett AFG, and Riello
40 F5, or F10 perform following preventative maintenance
annually, preferably prior to heating season. Refer to
burner manual provided with boiler.
1.
Fuel Filter Replace to prevent contaminated fuel from
reaching nozzle. Partially blocked fuel fi lter can cause
premature failure of fuel pump.
2.
Fuel Pump Unit Replace pump screen and clean pump
unit to maintain fuel delivery to nozzle.
3.
Ignition Electrodes Clean and adjust per
manufacturer’s recommendations, to maintain reliable
ignition of oil.
4.
Nozzle Replace to maintain safe and reliable
combustion ef fi ciency. Replace with nozzle as required
in charts located in this manual.
5.
Fan and Blower Housing Must be kept clean, free of
dirt, lint and oil to maintain proper amount of air fuel
requires to burn.
6.
Check Final Burner Adjustments.
If any component parts must be replaced, always use parts
recommended by burner manufacturer.
