Prepare the Fuel Unit for Air Venting
To vent air from one-pipe oil systems, attach a clear 
hose to the pump bleed port (item p in Figures 9 &

Professional Service 
Required
Incorrect installation, adjustment, and 
use of this burner could result in severe

commission of this equipment.
Skilled in the adjustment of oil burners using 
combustion test instruments.
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 CSA B139 and B140 in Canada).
Regulation by these authorities take precedence over

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.

Hot Gas Puff-back and 
Heavy Smoke Hazard 
Failure to bleed the pump properly could result in 
unstable combustion, hot gas puff-back and heavy 
smoke.
Do not allow oil to intermittently spray into a hot 
combustion 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.
