To the Owner:

Thank you for purchasing a Beckett burner for use 
with your heating appliance.  Please pay attention to 
the Safety Warnings contained within this instruction 
manual. Keep this manual for your records and provide 
it to your quali

fi

 ed service agency for use in profes-

sionally setting up and maintaining your oil  burner.

Your Beckett burner will provide years of ef

fi

 cient oper-

ation if it is professionally installed and maintained by 
a quali

fi

 ed service technician. If at any time the burner 

does not appear to be operating properly, immediately 
contact your quali

fi

 ed service agency for consultation.

We recommend annual inspection/service of your 
oil heating system by a quali

fi

 ed service agency. 

Daily – Check the room in which your burner/ap-
pliance is installed.  Make sure:
Air ventilation openings are clean and unob-
structed
Nothing is blocking burner inlet air openings
No combustible materials are stored near the 
heating appliance
There are no signs of oil or water leaking around 
the burner or appliance

Weekly - Check your oil tank level.  Always keep 
your oil tank full, especially during the summer, in 
order to prevent condensation of moisture on the 
inside surface of the tank.

Special Requirements - The 
installation of a burner shall be 

in accordance with the regulations of authorities having 
Jurisdiction.

For recommended installation practices in the U.S. 
refer to the latest edition of NFPA 31. 

 

(CSA-B139 and CSA-B140 in Canada.
