When inspecting and cleaning the fuel oil tips, please observe
the following:
• Vortometric oil nozzles are manufactured of stainless steel, with
all surfaces manufactured to close tolerances and highly polished.
Therefore, avoid marring the nozzle’s machined surfaces in any
way when the atomizer is dismantled.
• Never use abrasive cleanser or emery cloth on the internal sur-
faces of the nose cone. However, a wire brush may be used on the
outside surfaces of the nose cone where carbon has accumulated.
If the oil tip holes become blocked, you cannot clear the blockage by
forcing the atomizing medium through them. Instead, the tip must be
removed and cleaned out. Care should be taken when dismantling
and cleaning the oil tip to avoid burring or other damage. After re-
moving the tip, the recommended cleaning procedure is as follows:
1. Soak the tip in a solvent such as Varsol, especially if the atomizer
has been used with heavy oil.
2. Blow out the tip with compressed air in the reverse direction to
the oil flow.
3. Wash the tip again in solvent.
4. Select the correct drill size needed from Table 5.1. Use a new bit
to avoid potential marring. Insert the drill bit by hand into each
hole in the oil tip to clear any hard carbon or other residue.
Caution:
Forcing an oversized drill bit into the oil tip holes will ruin the tip.
5. Repeat Step 2.
6. Repeat Step 3.
7. Before reassembling the oil tip in the atomizer assembly, clean
out the oil feed pipe with either compressed air or solvent as
necessary.
