Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

I have a lanair mx200 that I cannot get to light.  It done this to me the other day and I drained about 5 gallon from the bottom and it worked fine for a couple days.  Tried to drain it today and it still won't light.  The only thing that comes out when I drain it  looks like oil.  Could the water not be settling out?   I'm about fed up with this thing temped to sell it.  It's been more trouble than its worth.
