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 qualifi ed service agency for use in profes-
sionally setting up and maintaining your oil burner.
Your Beckett burner will provide years of effi cient oper-
ation if it is professionally installed and maintained by
a qualifi ed service technician. If at any time the burner
does not appear to be operating properly, immediately
contact your qualifi ed service agency for consultation.
We recommend annual inspection/service of your
oil heating system by a qualifi 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.
