Hello,
Is it possible to combine all the venting of kitchen (microwave), bath, dryer in the attic to 1 exit wall vent outside?
I am assuming it's not allowed because it may cause the air flow to go backwards.
If I have to build 3 exit wall vent outside, how far apart do they have to be?
Is there a limit how long a duct can be for the kitchen (microwave)? The CFM is 300 and I am planning to use 4" metal duct.
Thanks
