Burner
A. Owner’s Information
Have your equipment inspected at regular intervals
by a qualifi 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 ineffi 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 effi cient, trouble-free operation. Please
take care of your equipment by following the warnings
provided and by immediately contacting your qualifi ed
service agency, if your burner is not operating properly.
This equipment should be serviced only by a qualifi 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.

Use only Beckett replacement parts
for continued safe operation of the
burner.
Have your burner, serviced annually by your qualifi 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 specifi ed by the
appliance manufacturer and replace the nozzle with
one having the exact specifi 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 Baffl e is in place, if
required, for the burner application. Omitting the baffl 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
specifi cations.
