Read alot of posts about the advance, most complaints seem to be about smoke in the hopper and temperature issues. I have not had any issues with these. My issues have been a bit more severe, most recently the metal brace behind the flame guide plates had cracked. Also in the last 2 years I am on my third gear motor, it is my understanding that the manufacturer has recognized a defect in the gearing of the motor, but no one seems to recognize the problems that I suspect are wrong with the stove. If any dealers and technicians have any ideas on why this keeps happening i'm axious for an answer. The gearmotor issue has also happened to my brother in laws accentra.
