Hi all,

I have a Pre-Lennox Whitfield Cascade. It has a single motor running both convection and exhaust fans. The stove is cleaned regularly and the chimney vacuumed frequently. I have noticed lately that there seems to be less air going to the firebox, yet the convection air is unchanged. Since one motor powers both fans I reasoned that the exhaust impeller may be sooted up. Does this seem probable? I can find no directions for cleaning the impeller for this kind of stove.

A couple other points: The owners manual provides no guidance for this kind of service, and also, if left on the high setting for any length of time, will overheat and shut down.

Thanks
