User care and maintenance
Refer only to the information on
this page, intended for your use.
The remainder of this manual is
intended only for your service
technician. Failure to comply could
result in severe personal injury,
death or substantial property dam-
age.
For other than routine maintenance, contact
a qualified service company. Perform the
following as needed.
• Keep the area around the burner clear
and free from combustible vapors and
liquids.
• Do not obstruct the flow of combustion
and ventilating air.
• Most motors currently used on residential
type burners use permanently-lubricated
bearings, and do not require field lubri-
cation. Read the label on the motor to
determine oiling needs, if any. Do not
over-lubricate. This can cause as much
trouble as not lubricating at all.
