Maintenance and Service
Oil Burner
It is recommended that the nozzle and oil lter be checked
before each heating season. Also recheck the conditions
shown on the Oil Furnace Start-Up Checklist on Page
2.
Always keep the valve shut off if the burner is shut
down for an extended period of time.
Flue Pipe
Have the ue pipe inspected annually by a qualied
service technician. If any soot or ash has formed inside
the ue pipe, remove and clean. If the ue pipe has any
holes or is rusted out, replace with a new ue pipe of the
same size. Inspect the ue draft control device and replace
if defective.
Blower
Blower motor is pre-lubricated and sealed for extended
operation. No further lubrication is required.
The blower assembly may be removed from the cabinet for
cleaning and servicing of the blower. Disconnect power to
the unit before servicing.
4. Power to the burner is interrupted, thus shutting down
the burner.
Blower
A direct drive blower motor contained within the furnace is
equipped with adjustable blower On and Off delays. These
delays are set by DIP switches located on the control
board.
Refer to Table 3 for DIP switch selection settings. The
standard setting for oil-red furnaces is 60 second On
delay and 2 minute Off delay.

Heat Exchanger
To clean the heat exchanger:
1. Remove the vent pipe from the furnace.
2. Remove the locking screws and the caps from the two
cleanout tubes; remove the ue access elbow.
3. Using a long spiral wire brush, sweep down the outer
drum of the heat exchanger. Using a shop vacuum
hose attachment, vacuum out all loose debris.
4. Remove the locking screw and cap from the inspection
tube and with the spiral wire brush reach upward
toward the rear of the heat exchanger to clean out the
crossover tube; replace the locking screw and cap on
the inspection tube.
5. Do not attempt to clean the combustion chamber, as it
can be easily damaged.
6. Replace the three previously removed cleanout caps
and ue access elbow, making sure to reinstall the
locking screws.
7. Brush out and vacuum the vent outlet area of the outer
drum and reattach the vent pipe.
8. Clean up around burner, blower deck, and vestibule
area.
Heat exchanger cleanout kit #ABRSH380-3 is available
from the manufacturer.
Emergency Fuel Pump Replacement
If replacement of the A2EA6520 fuel pump becomes
necessary, replace it with another Beckett CleanCut
fuel pump. In an emergency situation where the correct
replacement parts are not available, an A2VA7116 fuel
pump could be used. This option can produce a smoky
start-up and shutdown that could result in fouling of a heat
exchanger. This is only a short-term option and should
be used only until the correct parts can be obtained and
installed.
