Start the Burner

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 
Department. Carefully follow their directions. 
Keep a fi re extinguisher nearby and ready for use.

Starting the burner and venting air

Initiate a call for heat
While the ignition is on, press and release the reset button 
on the R7184 control (hold 1/2 second or less).  If the 
control has not locked out since it’s most recent complete 
heat cycle, the lockout time will be extended to 4 minutes 
(45 seconds in earlier units), and the ignition will remain 
on the entire heat cycle.
Bleed the pump until all froth and bubbles are purged. If 
prime is not established within the extended lockout time,

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.

Initial air settings (Table 5)

Loosen the air band and shutter, and adjust to the 

 

 

approximate fi ring rate settings given in Table 5.
These initial settings should be adequate for starting the 
burner. Once the burner is in operation, the air settings 
will be adjusted for best performance as discussed later in 
this manual.
Follow the procedures described later in this manual for 
fi ne-tuning the air settings.

Set appliance limit controls

Set the appliance limit controls in accordance with the 
appliance manufacturer’s recommendations.

Prepare the fuel unit for air venting

To vent air from the oil supply line, attach a clear hose 
to the pump air bleed valve (fi gure  9) on the fuel unit. 
Provide a container to catch the oil. Loosen the pump air 
bleed valve.
Vent the air as described in the next section under Start 
the burner
