Combustion Set-Up; Set Combustion With Instruments - Beckett 12Vdc SDC Manual

B. Combustion Set-up
Explosion and Fire Hazard
Failure to follow these instructions could
lead to equipment malfunction and result
in heavy smoke emission, soot-up, hot gas
puff-back, fi re and asphyxiation hazards.
Do not attempt to start the burner when excess oil has
accumulated in the appliance, the appliance is full of
vapor, or when the combustion chamber is very hot.
Do not attempt to re-establish fl ame with the burner
running if the fl ame becomes extinguished during
start-up, venting, or adjustment.
Vapor-Filled Appliance: Allow the unit to cool off
and all vapors to dissipate before attempting another
start.
Oil-Flooded Appliance: Shut off the electrical power
and the oil supply to the burner and then clear all
accumulated oil before continuing.
If the condition still appears unsafe, contact the Fire
Department. Carefully follow their directions.
Keep a fi re extinguisher nearby and ready for use.

As soon as burner motor starts rotating bleed all the air
from the pump. (Required with single-pipe systems.)
To bleed the pump, attach a clear plastic hose over the
vent fi tting. Loosen the fi tting and catch the oil in an empty
container. Tighten the fi tting when all air has been purged
from the supply system. Note: If the burner stops after a
fl ame is established, the unit probably requires additional
bleeding. Continue to bleed the system until the pump is
primed and a fl ame is established when the bleed valve
is closed.

The installation must strictly comply with all applicable
codes, authorities having jurisdiction and the latest revision
of the National Fire Protection Association Standard for
the installation of Oil-burning Equipment, NFPA 31 (or

1. Allow the burner to run for approximately 5 to 10
minutes.
2. 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 (or O
2 2
point for further adjustments.
Step 3: Increase the air to reduce CO
percentage point (O
approximately 1.4 percentage points).
Step 4: Recheck the smoke level. It should be zero.
3. This procedure provides a margin of reserve air to
accommodate variable conditions.
4. Once the combustion level is set, tighten the fasteners
on the air band and air shutter.
5. Start and stop the burner several times to ensure
satisfactory operation.
6. Test the equipment safety controls to verify that
