This applies to all controls, panels, enclosures, switch-
es, and guards or any component with a cover as part 
of its design.

Safety controls are designed and installed to provide 
protection.
Do not tamper with, or bypass any safety control.
If a safety control is not functioning properly, shut off 
all main electrical power and fuel supply to the burner 
and call a qualifi ed service agency immediately.

Prepare the burner for 

start-up

This burner must be installed and prepared for start-up 
by a qualifi ed service technician who is trained and ex-
perienced in commercial oil burner system installation 
and operation.
Do not attempt to start the burner unless you are fully 
qualifi ed.
Do not continue with this procedure until all items in 
the “Prepare the burner for start-up” section have been 
verifi ed.  
Carefully follow the wiring diagrams, control instruc-
tion sheets, fl ame safeguard sequence of operation, test 
procedures and all appliance manufacturer’s directions 
that pertain to this installation.
If any of these items are not clear or are unavailable, 
call Beckett at 1-800-645-2876 for assistance.

7.  Recycle — If the fl ame is lost while the burner is fi ring, the 

control shuts down the burner, enters a 60-second recycle 
delay, and then repeats the ignition steps outlined above. If 
the fl ame is lost three times in a row, the control locks out 
to prevent continuous cycling with repetitious fl ame loss 
caused by poor combustion.

8.  Burner motor-off delay — If applicable, the fuel valve is 

closed and the burner motor is kept on for the selected post-
purge time before the control returns the burner to standby.
