NOZZLES
AND ELECTRODES:
Use the proper size, spray angle, and spray pattern nozzle.
Refer to the
recommended
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 the bend the electrode tips. After installing the nozzle,
reassemble
the nozzle line electrode assembly and set the electrode tip spacing.
Depending on the bumer
purchased,
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 spacing on Beckett, Carlin,
and Riello t_umers.
FINAL
BURNER
ADJUSTMENTS:
Final burner adjustments
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 over fire to verify that it is between M).01" WC and -0.02"
WC,
otherwise
adjust the draft as necessary.
After operating
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 boiler
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 reading is a trace, measure the COz and as an insurance margin increase the air to
sufficiently
reduce the CO2 by 1/2% to 1%.
Ira clean fire cannot be obtained, it will be necessary to verify the burner head and electrode alignment.
Proper electrode alignment
figures are presented on the following pages.
If the fire continues
to be smoky,
replace the nozzle with a correct replacement.
Once the burner is completely
adjusted, the burner should be 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.
OIL BURNER
MAINTENANCE:
For the Becket/: AFG, Carlin EZ-1 or EZ-2, and the Riello 40 F3, F5, or
F10 the following preventative
maintenance
items should be performed annually, preferably prior to the
heating season.
1. Oil Burner Motor - For Beckett and Carlin burners, add 2 -3 drops of non-detergent
electric motor oil
to each oil cup located at the front and rear of the motor (Riello burners are permanently
lubricated).
Excessive
oiling will shorten the life expectancy
of the motor.
2. Fuel Filter - This should be replaced so as to prevent contaminated
fuel from reaching the nozzle.
A
partially blocked fuel filter can cause premature
failure of the fuel pump.
3. Fuel Pump Unit - Replace pump screen and clean pump unit to maintain fuel delivery to the nozzle.
4. Ignition
Electrodes
- Clean and adjust as per manufacturer's
recommendations,
so as to maintain
reliable ignition of oil.
5.
Nozzle - Replace so as to maintain safe and reliable combustion
efficiency.
Always replace with the
exact nozzle as required in the charts in the back of this manual.
6.
Fan and Blower Housing
These must be kept clean, free of dirt, lint and oil so as to maintain the
proper amount of air the fuel requires to burn.
7.
Check the final burner
adjustments.
I NOTE:
If any component
parts must be replaced, always
I
i
use parts recommended
by the burner manufacturer.
