How much CFM does the fan of a gas brick oven need to be?
I have a gas brick oven that will have a direct vent to the roof of my building. The existing vent itself is massive for this oven (15"), and the fan is large too but I want to use them because they are there. I don't know how big the fan is or what its CFM rating is, but I want to know in general what CFM rating a brick ovens fan would need to be? We're talking about 200,000 BTU, and this is the oven http://www.bakrico.com/details.asp?pro_id=47.Any ideas?
