Default Air mass movement calculation

Hi,
This was my best guess as to the appropriate forum - it's an oddball question but please bear with me. (The answer has been bugging me.) I am installing a wood stove in my home. I plan on buying one of these:

http://www.plowhearth.com/large-caframo-ecofan.htm

The details state:
Small Wood Stove Fan circulates up to 100cfm,
4-1/4" x 5-1/2" x 8-1/2"H
Large Wood Stove Fan circulates up to 150cfm,
4-1/4" x 5-1/2" x 9-1/4"H

I was thinking about getting crafty and trying to replace the aluminum blade with a wooden 2 or 3 blade prop for RC. I know I have to deal with the inner diameter of prop, possible weight issues etc. But, wouldn't it be nice to have that sitting on my stove! So, my question is how can I calculate square footage of air mass moved to pitch? I also realize that the actual blade size is not listed but the height of the unit is so it would have to be less than 8.5 or 9.25. Recommendations? Thank you very much.
