Help! Venting hell!!
Let me start by saying I live in Michigan. My wife and I are building a dream home but with a builder that doesn’t do custom. Think of it as you get-what-you-get situation. So we’re going to do a minor kitchen renovation before even moving in. I always wanted a 36” range or cooktop and am willing to do quite a bit of work to make it happen. And of course you need a nice vent hood to go with it. And that is where the complications start.
I don’t care for the builder’s kitchen vent option. Their design has a downward pointing 90 elbow right, square 3.25”x10” ducting between the 2x4 walls, then into basement, and out the side of the house… seems like a bad design to me. I’m thinking some soffits, vertically up, horizontally over, and out the garage wall (or roof) is better. And then I get to pick whatever size duct I want.
But local code MUA requirements are really throwing a wrench in our plans. I’d like to avoid it as best as possible because of our cold winters. I heard someone call this ‘venting hell’. Sounds spot on to me.
So here is my best stab at selecting a cooktop, vent, and ducting:
- Viking 6 burner 36” cooktop VGSU164-6BSS, capable of 66k BTUs
- Viking 36” W x 24” D wall canapy vent hood VWH36481, but pair it with a 300 CFM internal blower (I actually surprised to see that Viking offering such a blower ��" model number VINV300)
- 10” round exhaust duct work
I think the benefit to this combo is threefold:
- I get the 36” cooktop with the much desired real estate
- The vent hood has good 24” deep geometry that will help the capture smoke and grease, albeit with lower max CFM output
- Duct in 10” round for universal vent hood/blower changes in the future. If I need more CFM and are willing to pay the cost for heated MUA system, then I just have to add the MUA system.
My only hesitation at this point is the 10” duct with a low 300 CFM. Are there any adverse effects? Sure seems unusal… but in the interest of avoiding really cold MUA in the dead of winter I think this might be the best compromise. Thoughts?
