Owner’s Responsibility
Incorrect installation, adjustment, and
use of this burner could result in severe
personal injury, death, or substantial
property damage from fi re, carbon
monoxide poisoning, soot or explosion.
Contact a professional, qualifi ed service agency for the
installation, adjustment and service of your oil heating
system. This work requires technical training, trade
experience, licensing or certifi cation in some states and
the proper use of special combustion test instruments.
Please carefully read and comply with the following
instructions:
Never store or use gasoline or other fl ammable liquids
or vapors near this burner or appliance.
Never attempt to burn garbage or refuse in this
appliance.
Never attempt to light the burner/appliance by throwing
burning material into the appliance.
Never attempt to burn any fuel not specifi ed and
approved for use in this burner.
Never restrict the air inlet openings to the burner or
the combustion air ventilation openings in the room.
