I have a 3' flue and the most I ever got was 35/36 gph and that was with hardwood. People will tell you you can and maybe they actually are or think they are but not.
I'm installing a flow gauge this year from a city water dept. I will have a bypass around the meter just in case it fails and have to wash the meter every night with water so it doesn't get gummed up with stick sap.

I noticed this year Leader bumped up the GPH evap rate on 2x6 from what they have posted in years prior, but maybe they are doingsome thing different than in the past.
I never had insulation in my arch before and going to redo inside arch here soon I'm hoping it will make a difference.
