VERY IMPORTANT
Before installing a new nozzle, it
is very important to flush the
nozzle line and adapter
with at
least a pint of oil pumped through it to
remove sludge and dirt. Or you can
blow out the line with compressed air if
it’s available. Failure to do this has been
the reason for numerous callbacks for
plugged nozzles.
The nozzle orifice is polished to
a glasslike finish.
Don’t ruin it with
a wire or pin, or by bumping it with a
wrench. This can cause streaks in the
spray.
Don’t blow into the nozzle. While
this may seem to be the handiest and
quickest way to “clean” a nozzle, you
run the risk of contaminating it instead.
A nozzle can become overheated
due to back pressure in the
combustion chamber.
This results
in coke and sludge formation both
inside and outside of the nozzle. To
correct this problem, set the over fire
draft for at least .02 inches of water
column or follow furnace or boiler
manufacturer’s specifications.
On a conventional installation,
be sure the end of the burner
tube is flush or slightly set back
with the inside wall of the combustion
chamber to prevent the nozzle from
becoming overheated. Follow
manufacturer’s specifications when
available.
