Any of you Orlan/Eko users ever running in to, what I call the wood "bridging" in the firebox. I happens every once in a while, that the glowing embers over the nozzle burn away and leave an opening between the nozzle and the wood load. This results in more smoke from the stack than I like, because the secondary burn stops. When I stir the load a bit so it comes down, it goes right back to full gasifying instantly. Has anyone run into this and maybe come up with a solution for it. I do not have the time to baby sit the unit, so looking for some ideas. Thanks, Henk.
