Use a Chimney with Oak Lump Charcoal over the propane Wok burner to get the fire goin lickty split...Drop in fire box, place logs in till they blaze away and the fire dies down a bit leaving a nice bed of glowing coals...this also brings the temp up in the drum to over 300*
Today I cleaned out the grease and hosed out the bottom to get the gunk out...put some water on the bottom to keep it nice and moist...
What you are looking for is a thin clean exhaust from the smoke stack...for this you need to keep the vent open, when the fire dies you close down the vents a bit....till yo have to add new fuel on the fire. Then you have to reopen...
