Hi all. Myself and a co-worker recently completed the install of this M55 Cast (Beach in colour), at our workplace (we sell a wide variety of hearth products here in eastern Canada). We used 4" ICC pellet vent and adapted into an existing 6" selkirk chimney. We've ran close to 15 bags of Eastern Embers through it so far with great results. The unit is one of the quietest I've come across and throws a tremendous amount of heat. the only downfall if you want to call it that, is like other M55's, the air wash system fails to operate in the far right corner. we've had a large amount of inquires about the unit so far and I would certainly recommend to potential buyers.
