For those of you with Kuma Sequoia inserts. I would be interested in knowing your assessment of the "natural convection". It won't be my main source of heat in the house and I wondered if I didn't get a blower if that might help my 600 square great room from getting to hot. Also, I was wondering about how dirty the glass gets, especially if you compare them to other stoves. Anybody have the Ashwood insert, and thoughts on that stove?
