Nozzle Care and Service Tips
An oil burner nozzle is an intricate piece of hardware, designed to
do an accurate job of atomizing and metering fuel oil in the spray
pattern best suited to a given burner. You can help assure top
performance of this vital component by following the important
guidelines in this section.
Until installation, keep nozzles
in their original containers
and
preferably in a suitable box or rack.
They should not be permitted to roll
around in a drawer or toolbox, or
carried loose in pockets. On service
calls, they should be kept in a clean
nozzle box.
Handle the nozzle carefully
after removing from its individual
container. Pick it up by the hex flats
and by all means avoid touching the
filter or strainer with greasy hands.
This can force foreign material into
the nozzle where it can finally work
its way into the slots. The possibility
for problems is even greater with
nozzles of lower flow rates since they
have smaller slots…easier to clog.
Nozzles should always be
handled with clean tools…
again to reduce the possibility of
contamination. To properly service a
nozzle and check its performance,
it’s recommended that you use a
pressure gauge, vacuum gauge,
nozzle changer and flame inspection
mirror.
Be sure the strainer or filter is
in place
on the nozzle before
installation. Do not disassemble the
nozzle before installing it because
great care has been taken to make
sure the nozzle is absolutely clean on
delivery.
