Nozzles used on Power Flame Type C burners are of two types:  simplex and internal bypass.  The simplex nozzle is normally used on smaller burners in the three to eight gallons  per  hour  range.    The  bypass  nozzle  is  used  for larger inputs requiring higher turndown or more sophisticated air/fuel control.  Both types of nozzles have GPH ratings stamped on the side.  Stamped ratings are based on 100 psig.  The burners operate in the 300 psig range.    See  pages  30  and  31,  Tables  8  and  9  for  flow rates, pressure and sizing information. 2. When removing or replacing the oil nozzle and electrode assembly,  take  care  to  prevent  damage  to  the  ignition wire. 3. The nozzles should be removed from the nozzle adapter by    use    of    the    proper    wrench.        They    should    be disassembled    and    thoroughly    cleaned    with    a    liquid solvent (preferably non-flammable) and a brush. 4. Do  not  use  a  screwdriver,  wire  brush  or  similar  metallic objects  to  clean  nozzles.    Damage  to  orifices  or  spray slots result in off-center or “sparky” fires. 5. The nozzle should be seated firmly in the nozzle adapter to prevent leaks. 6. If a nozzle is damaged or burned, replace it. 7. The  entire  oil  tube  and  nozzle  assembly  (the  oil  drawer assembly) may be removed for ease of service. 8. When cleaning and taking the nozzle apart, do not force it. 9. For  additional  information  on  bypass  nozzles,  see  page 30.    Note  that  the  Teflon  seal  in  the  Monarch  F80BPS and  Delavan  33769  nozzles  is  an  integral  part  of  the nozzles and that if the seal is removed accidentally, the nozzle  must  be  replaced.    On  the  Delavan  30630  and 30637  nozzles,  the  seal  normally  remains  in  the  nozzle adapter.   When the nozzle is removed from the adapter, the seal should also be removed and replaced with a new seal. Oil Pump or Oil Flow Problems and Typical Solutions NO OIL DELIVERED 1.  Reversed pump rotation 2.  Suction lift too high (See page 10, Fig.  10) 3.  Air leak in suction line 4.  Pump not primed, or has lost prime 5.  Pump coupling not installed properly 6.  Pump defective 7.  Line plugged 8.  Valve closed CAPACITY TOO LOW 1.  Suction lift too high (See page 10, Fig.  10) 2.  Air leak in suction line 3.  Suction line too small (See page 10, Fig.  10) 4.  Check valve or strainer is obstructed or dirty 5.  Mechanical defects pump badly worn or seal defective NOISY PUMP 1.  Air leak in suction line 2.  Pump not securely mounted 3.  Vibration caused by bent shaft or misalignment 4.  Pump overloaded 5.  Suction line vacuum so high that vapor forms within the liquid (see page 10, Fig.  10) PUMP LEAKS 1.  Cover bolts need tightening; gasket broken or defective 2.  Mechanical seal (used on certain models) may be scratched, due to dirt 3.  Inlet head pressure too high.  Install a pressure reducing valve set at 3 psig or less. 4.  Oil line fittings not tight For additional oil pump information, refer to the oil pump manufacturer's product bulletin supplied with the burner.
