Yearly Checklist
1. Test (leak test) safety shut-off valves for tightness of closure.
2. Test pressure switch settings by checking switch movements
against pressure settings.
3. Visually check ignition cable and connectors.
4. Check the refractory combustion block to ensure that it is not
badly cracked or spalled. Minor hairline cracks are of no
consequence and should be considered normal. Examine the
refractory around the throat cone, since this area is where
breakage can easily occur. If repairs are needed to this area,
ensure that any new refractory is installed to the original
contours and surface texture.
5. Remove the pilot assembly and examine the ceramic insulators
on the spark rods. Clean the spark rod end with a fine emery
cloth. Adjust the spark gap to no more than 1/8".
6. Remove the gas gun assembly and clean the gas orifices. Use
compressed air to blow all scale or dust out of the ports.
7. Remove the oil gun assembly, and clean the oil injection orifices
and atomizing air nozzles according to the instructions that
follow in this chapter.
Fuel Oil Tip Cleaning
Vortometric burner sizes 6V through 12V use an oil nozzle held by
a retaining ring. With these sizes, the nose cone assembly must be
unscrewed from the body to remove or replace the entire tip.
Vortometric burner sizes 14V and larger use an oil nozzle which is
made in two pieces, which allows the outer end of the tip to be re-
moved from the nozzle body. Therefore, the tip head containing the
oil orifices can be removed for cleaning without dismantling the en-
tire atomizer.
Note:
On a burner with CLOCKWISE air rotation, the tip head has LEFT
HAND threading. On a burner with COUNTERCLOCKWISE air
rotation, the tip head has RIGHT HAND threading.
