Start the Burner
Starting the burner and venting air
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 ac-
cumulated oil before continuing.
If the condition still appears unsafe, contact the Fire De-

and result in heavy smoke emission,
soot-up, hot gas puff-back, fi re and
asphyxiation hazards.
Explosion and Fire
Hazard
Do not allow oil to intermittently spray into a hot com-
bustion chamber while bleeding.
Install a gauge in the nozzle discharge port tubing or
fully open the pump bleed valve to prevent oil spray
from accumulating in the combustion chamber when
venting air from the fuel pump.
Ensure that all bubbles and froth are purged from the
oil supply system before tightening the pump air bleed
valve.
