Maintain & Service
Burner
A. Owner’s Information
Have your equipment inspected at regular intervals
by a quali
fi
ed service agency to assure continued
proper operation. The burner should be adjusted using
dedicated combustion test equipment. Failure to properly
set the burner could result in inef
fi
cient operation, and/or
conditions that could potentially cause severe personal
injury, death or substantial property damage.
B. Owner Service and Maintenance
Properly installed and maintained, your SDC burner will
provide years of ef
fi
cient, trouble-free operation. Please
take care of your equipment by following the warnings
provided and by immediately contacting your quali
fi
ed
service agency, if your burner is not operating properly.
This equipment should be serviced only by a quali
fi
ed
service agency. The appropriate test instruments must be
used.
Daily
Check the area around your burner/equipment to make
sure:
Nothing is blocking the burner inlet air openings.
Air ventilation openings are clean and unobstructed
and the exhaust is not crusted.
No combustible materials are stored near the
equipment.
There are no signs of oil or water leakage around
the burner or equipment.
C. Extended Down Time
If the equipment will be stored for an extended period of
time, ensure the fuel tank is full and add a fuel stabilizer
to the tank.
D. Regular Service/Maintenance

○
Use only Beckett replacement parts
for continued safe operation of the
burner.
Have your burner, serviced annually by your quali
fi
ed
service agency. The following components/assemblies
should be checked/adjusted/replaced on a regular basis.
Refer to the Replacement Parts exploded view for part
locations.
Replace the oil supply line
fi
lter, if applicable.
The line
fi
lter cartridge must be replaced to avoid
contamination of the pump and nozzle.
Inspect the oil supply system. All
fi
ttings should be
leak-tight. The supply lines should be free of water,
sludge and other restrictions.
Remove and clean the pump strainer.
Verify the nozzle is the one originally speci
fi
ed by the
appliance manufacturer and replace the nozzle with
one having the exact speci
fi
cations from the same
manufacturer.
Clean and inspect the electrodes for damage,
replacing any that are cracked or chipped.
Check electrode tip settings. Replace electrodes if
tips are rounded.
Inspect the igniter spring contacts. Clean or replace
if corroded.
Clean the cad cell, if applicable.
Make sure Low Firing Rate Baf
fl
e is in place, if
required, for the burner application. Omitting the baf
fl
e
can result in unacceptable burner combustion.
Inspect all gasket including the igniter base plate
gasket. Replace any that are damaged or missing.

Allow the burner to run for approximately 5 to 10
minutes.
Follow these four steps to properly adjust the
burner:
Step 1:
Adjust the air until a trace smoke level is
achieved.
Step 2:
At the trace of smoke level, measure the
CO
2
(or O
2
). This is the vital reference
point for further adjustments.
Step 3:
Increase the air to reduce CO
2
by 1
percentage point (O
2
will be increased by
approximately 1.4 percentage points).
Step 4:
Recheck the smoke level. It should be zero.
This procedure provides a margin of reserve air to
accommodate variable conditions.
Once the combustion level is set, tighten the fasteners
on the air band and air shutter.
Start and stop the burner several times to ensure
satisfactory operation.
Test the equipment safety controls to verify that
they function according to the manufacturer’s
speci
fi
cations.
