the dipstick or to center of sight glass window found on
the rear of the pump. During the break-in-period, make
sure the oil is changed after the first 50 hours of opera-
tion. After that, replace oil every year or 500 hours of
operation, whichever comes first.

Heating Coil

Coil Descaling: In hard water areas, scale buildup
within the heating coil will occur. Scale deposits will
decrease the water temperature rise and may eventu-
ally clog the heating coil. Contact your local service
center when descaling is needed.
Coil Desooting: Poor grades of fuel oil or inadequate
combustion air will cause heavy soot buildup on the
outside surface of the heating coil. These deposits will
insulate the coil. This will restrict the air flow through
the coil, further aggravating the soot buildup. Contact
your local service center when desooting is needed.
