Onan 3600 lp

Have a fault code reading 15 on an Onan LP 3600 and it says to drain the oil from the supply system. Any info on where to drain it?
  • Oil in the supply system
    They are taking about oil in the l.p.

    This would mean disconnecting the l.p. Line, From the generator and cleaning/replacing the pressure/vapor regulator

    If that doesn't work, you will need to clean out the l.p. Tank and lines
    I would check with a propane distributor who services tanks etc..
  • I would suggest a call to Onan. They have seemed very receptive to my questions in the past. ST
