Kitchen venting

Thanks William, do you think the manufactures care if you do or you don’t. NO!!! They want to sell sell sell and to put a hood in costs big bucks more depending on location requirements. I have always said this to my clients when they say **but but **the manufacture says it is OK or the AHJ says it is OK ect.

You are getting no argument from me.
I am just saying that it is recommended, however, nowhere in the IRC is it required to have the fan vented to the exterior.

Here is another thread where we talked about it:
