CAUTION
Do not run boiler unattended until the following procedure is
completed.
NOZZLES AND ELECTRODES
8.
: Use the proper size,
spray angle, and spray pattern nozzle. Refer to the recommend-
ed nozzle selection charts at the end of this manual. To install a
nozzle, remove the nozzle line electrode assembly, if necessary
remove the retention ring assembly, and then install and tighten
the nozzle. Be careful not to damage the electrode insulators or
bend the electrode tips. After installing the nozzle, reassemble
the nozzle line electrode assembly and set the electrode tip
spacing. The electrode tip spacing may need to be set prior to
reassembling the nozzle line electrode assembly. Refer to the
figures on the following pages for setting the electrode tip spac-
ing on Beckett.
FINAL BURNER ADJUSTMENTS
9.
: Final burner adjust-
ments must be made using combustion test instruments. Initial
settings for the burner are shown at the back of this manual.
Set the burner accordingly. Check the draft breech to verify
A.
that it is between 0.00” WC and -0.05” WC, or otherwise
adjust the draft to -0.05” WC (or less than zero.) After operat-
ing 10 minutes to warm up the boiler, use the combustion test
equipment to take a smoke reading in the flue pipe between
the boiler and the draft regulator. The smoke reading should
be zero to a trace (Shell Bacharach Scale). At times a new boil-
er requires more than 10 minutes to burn clean due to the oil
film on the new heat exchanger. If the smoke reading is zero,
gradually close the burner’s air adjustment to obtain a smoke
reading showing a trace smoke reading. Once the smoke read-
ing is a trace, measure the CO2 and as an insurance margin
increase the air to sufficiently reduce the CO2 by 1/2% to 1%.
If a clean fire cannot be obtained, it will be necessary to verify
B.
the burner head alignment. If the fire continues to be smoky,
replace the nozzle.
Once the burner is completely adjusted, the burner should be
C.
started and stopped several times to assure good operation
with no fluttering or rumbling. Verify that there are no oil
leaks and then record the nozzle size, oil pressure, combustion
readings, and air settings on a tag or label that can be attached
to the burner or, boiler.

CHECk THERMOSTAT OPERATION:
11.
The thermostat
location has an important effect on the operation of the boiler sys-
tem. Be sure to follow the instructions included with your ther-
mostat. Typically, the thermostat is located about five feet above
the floor on an inside wall. The thermostat should be located to
sense average room temperature, so avoid the following:
TABLE 13: THERMOSTAT LOCATIONS TO AVOID
DEAD
SPOTS
HOT SPOTS
COLD SPOTS
Behind doors
Concealed pipes
Concealed pipes
or ducts
Fireplace
TV sets
Stairwell drafts
Corners &
alcoves
Radios
Door drafts
Lamps
Unheated room on
other side of wall
Direct sunlight
Kitchens
Make certain: once the room temperature reaches the selected tem-
perature setting, the thermostat should turn the boiler’s burner off,
and once the room temperature falls a few degrees the boiler starts
operating again.
