Kitchen Vent Hood Ducting

The kitchen needs a vent hood. Without it the kitchen becomes greasy and smelly and attracts vermin. Someone had created a makeshift vent hood but it was terrible and gross so I decided to put in a decent "pro-sumer" model I got used for $150.

How it was when I got it. Low homemade hood, 30" range, and weird spacer block

I got an old 38" wedgewood to properly fill the space (and had to add a gas line (link) because it was originally electric).

I found this on houzz. I decided this look would be good and pretty cheap. I needed a 36" hood (standard) for the 38" range.

Here is the ducting I needed. Backdraft Dampener, on the right is a flap that acts as a one way valve

Normal hood vent sizes are 7 and 10". This was 8". It came with a built in backdraft dampener. I had to get a 8" elbow which is available at HD. The 8" wall vent was from a specialty store because HD only has 7" wall vent w/flapper which is for under-cab or under-mic hoods rated at lower CFM. You need there to be a flap in the vent or a separate "backdraft dampener" or your heating will escape out of the kitchen easily.

The hood should be placed 30-36" above the range. The range and countertop are always at 36". I am 6'4" and want the height at the max.

Ideal vent height is near the wood trim above

It looked close - but sliding the wall vent up under the trim close measured for up to 3' so it wasn't going to interfere much.

Yep that's as high as it gets and I'll be able to get near max height

You can see the hooks that it hangs on in the zinc coating (gold). The floppy little box is for wiring

Now I need to wire it up. I used a 15A breaker I had lying around. 15A in the kitchen is OK for lights and the vent hood and maybe the fridge and gas range although I'm not sure. 15A means you can use 14 gauge wires. I just bought one roll of 12ga wires (bigger) so I can use it with both 15 and 20A circuits.

Hey it works!

I put on the cover. It's simply a piece of stainless steel. Looks great
