Reply to comment by caucasian88 in Ducting for under cabinet range hood, how to offset to get by stud? by ninian1927

I have a gas range, it's 44,000BTUs. Perhaps you're right. The range maxes out at 900cfm but I imagine only having it on level 1/2 most of the time. I could go down to the 600cfm option and use 6 inch. I may or may not still hit the stud but would have to do some cutting to see.

100 cfm per 10,000 btu. You're super oversized.

From different research I'm not sure the CFM advertised is true CFM so they say to overshoot what you need.. but you're right I don't need 900cfm but it's 4 speed so I'll likely run it much lower.
