What causes the chimney on my OWB to puff like a locomotive? Kinda like muffled explosions. Just happens once in a while. It's like the smoke coming out dwindles a bit and then WHOOOF! a big puff of smoke, soot and sparks out the chimney, along with smoke blowing out a little around the door gasket.
It's almost like unburned gases build up inside and ignite. Not worried, just curious. If nothing else, it keeps my chimney clean.:msp_rolleyes:
