HAUCK LONG NOSE STARJET BURNER LNSJ360 – LNSJ980

Page 29LNSJ -9COMPRESSED AIR/OIL ADJUSTMENT1. Air and fuel flows and pressures can be observed at the burner using the compressed airand fuel flow meters and corresponding pressure gauges (see Figure 17).2. Compressed air supply pressure to the inlet of the compressed air manifold must be 90 psig(620 kPa) or greater. The supply pressure is measured via the gauge on the inlet to thecompressed air flow meter (see Figure 17). The compressed air low supply pressure switch ispreset at 60 psig (414 kPa). Set point adjustment may be required depending on the burnerand compressed air piping specifics.Figure 17. Compressed Air Manifold DetailX7303(NOT TO SCALE)3. For the compressed air manifold to function properly, the impulse line and upper chamber ofthe pressure reducing regulator must be loaded with oil by opening the vent valve on theregulator until oil vents, then closing the vent valve.4. Final compressed air flow and pressure adjustment is made via the compressed air trimvalve (see Figure 17). With the burner at high fire, adjust the trim valve until the compressedair burner inlet pressure gauge, located downstream of the trim valve, reads approximately60 psig (414 kPa). The compressed air low atomizing air switch is preset at 5 psig (34.5 kPa).Set point adjustment may be required depending on the burner and compressed air pipingspecifics.5. Compressed air flow can be read directly from the compressed air flow meter. Refer toCompressed Air Flow Meter section and Figure 19 for detailed instructions on how to readthe compressed air flow meter. Verify that both the compressed air flow and burner inletpressure, from step 4, meet or exceed the values given in Table 6 and/or the additionalburner capacity and performance data sheets.
