Beckett Burner CF500 Manuel D’Utilisation

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 but-
ton 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 igni-
tion 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, the control will lock out. Press the reset button to 
reset the control and return to the functions listed in the 
previous step.

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.

Repeat the previous steps if needed, until the pump is 
fully primed and the oil is free of bubbles. Then ter-
minate the call for heat, and the control will resume 
normal operation.    

If the control locks out three times in a row without a 
complete heat cycle between attempts, the lockout be-
comes restricted. A qualifi ed service technician should 
be called to inspect the burner. 

 

 

   

Any time the motor is running, press and hold  the reset 
button to disable the burner. The burner will remain off 
as long as the button is held and will return to standby 
when released

   

While the burner is fi ring, and after the ignition has 
been turned off, press and release the reset button (hold 
1/2 second or less) to check the cad cell resistance. The 
LED will fl ash 1 to 4 times, depending on the cad cell 
resistance (refer to the table below).
