I have an Avalon Olympic and use the front blower to increase the heat output. And believe me, this stove can produce the heat. I do understand that burning wood creates dust and the blower unit helps spread it a bit. With this stove, the blower is located on the bottom front and draws air and dust within the air chamber. I vacuum the air chamber, which surrounds the fire box, as best as a residential vacuum or wet vac can reach and have even used a damp cloth with a bent coat hanger to reach what I can see. I would like to know of any tricks of the trade or helpful technique for cleaning the air chamber. Does anyone make a vacuum attachment thin enough to fit inside?
