BURNER MAINTENANCE
SCHEDULED MAINTENANCE
OILING MOTOR
Proper lubrication of the motor will prolong its service life.
Oil sleeve bearing motors with 6 drops of SAE 20 oil once a
year. DO NOT OVER OIL. Ball-bearing motors do not
require oiling under normal service conditions. The bearing
type is printed on the motor nameplate.
FILTER
The oil filter cartridge should be replaced once a year so the
fuel oil will not become contaminated and plug up fuel pump
and nozzle of oil burner.
NOZZLE
The nozzle should be changed at least once a year before
the start-up of the heating season. Replace with proper
nozzle.

contamination.
FAN & BLOWER HOUSING
This must be kept clean, free of dirt and lint. Open the
transformer and off cycle damper to check fan blades from
above.
ELECTRODE SETTINGS
This is very important for reliable ignition of the oil; check
these once a year in accordance with the instructions
provided in this manual. Replace electrodes if worn
excessively or if porcelain insulator is oil soaked or cracked.

BLOWER WHEEL REPLACEMENT
If the blower wheel or motor is ever replaced or removed,
the spacing between the blower and the motor must be
checked to ensure proper burner function.
The proper spacing is 9/64" (or 0.140") between the fan and
the motor face. This is slightly more than 1/8".
SUNTEC PUMP INSTALLATION INFORMATION
GENERAL INFORMATION
Long or oversized inlet lines may require the pump to
operate dry during initial bleeding period. In such cases,
the priming may be assisted by injecting fuel oil into the
pump gearset. Under lift conditions, lines and fittings must
be air tight. To assure this, "Pipe Dope" may be applied to
both the used and unused inlet, and both return fittings.
MOUNTING POSITION
Model "A" Single Stage Fuel Pump may be mounted in any
position. Model "B" Two Stage Fuel Pump may be mounted
in any position except upside down (1/8" ports pointed
down).
VACUUM CHECK
and enter
In single pipe installations , a Vacuum Gage may be
installed in either of the 1/4" inlet ports or in the 1/8" return
port, whichever is most convenient. The Model "A" pump
should be used where the vacuum does not exceed 6" Hg.
single pipe and 12" Hg. two pipe. The Model "B" pump
should be used where vacuum does not exceed 17" Hg.
Remember, running vacuum is the total of all pressure
drops (ΔP) in the system from the tank to the inlet of
the pump.
