Almost a disaster in progress going on at my house. Bought a new gas stove to replace the electric one. It sits next to an interior wall, and to make a long story short...
The previous owner framed up a big sheetrock edifice thing to accomodate the microwave oven / vent hood over the electric stove. Getting a look at the underside of it with the microwave gone, I can see that the only way to vent it out thru the roof is to (maybe) run it out thru the same flue that services the gas water heater downstairs. There's one of those pie-plate looking covers on the flue inside the "edifice", facing towards the stove. That is, IF a human being can figure out a way to get their hands up in there and assemble and fit a flue.
I asked a gas company tech about this and he told me the newer gas ranges don’t need venting. I thought about it and concluded it has something to do with pilotless ignition.
I’ve never seen a vented gas stove. Not sure why it would need a vent other than to remove cooking odors.
The hood is for venting cooking exhaust, smoke, odors, the like.

My fiancee’ a general contractor of 30 years is sitting here next to me and he says a charcoal filter will not take the carbon monoxide out.
He says you cannot vent two appliances through on vent in a closed areas as the place where you add the second appliance will leak.
You need a 4 or 6 inch vent going out through the roof that comes down and hooks onto the microwave fan vent. You have to take the blocker out and change the position of the motor and squirrel cage so that it will blow up instead of out the face of the microwave. A job for a licensed professional who will know the codes in your area.
It does't need to be vented either.
I am a licensed plumber!
Do not vent anything into that water heater vent!
Gas ranges do not need a vent.
Sometime the range hood is vented through the roof to take odors and such to the exterior!
To, successfully tie two vents together you would need to increase the size to the proper diameter.
Plus vented gasses have to have heat to work so the range would never generate enough heat to vent anything out in conjunction w/ the WH vent!
Residential gas stoves require no venting for the byproducts of combustion.
The amount of CO generated, and the usage time, is too small to require it. Just don’t use it to heat your house.
There is no vent pipe. Like on a dryer. When cooking food the vent is either a vent hood. Or on a cabinet mounted microwave.
If you have black soot in your kitchen, you need a cooking class.
I’ve had gas stoves all my life...both natural gas and propane. They are never “vented”. At the most, and this is just for convenience and not code, you might have a fan hood. But it’s not required.
Apples/oranges,
there is venting the gas fumes(c-monox) and venting the cooking fumes........The range hood is for venting cooking smoke,steam whatever
I have a gas range and it is not vented like the hot water heater.....
However the GC above is correct the range hood w/ a fan and damper sys.
will take out cooking odors and heat. But is not a design intended to remove vent gasses from a gas appliance!
By “venting”, I presume you mean your range hood. If so, *do not* connect that to your chimney flue. That’s a no-no.
To be proper,the range hood must be vented to the outside, although some of them just vent to the attic, as long as it’s well ventialated. I don’t think that’s technically “kosher”, though.
If you mean venting in the sense of venting the byproducts of combustion, guess what? You don’t.
Believe it or not, they simply stay right in your house. Natural gas burns cleanly, and it is not required to vent the stove.
Kinda makes you wonder why the big deal with venting things like your water heater and gas fireplace. No? But that’s the way it is.
I guess the leg they have to stand on is that cooking is limited. You aren’t running all your burner all day long.
Anyway, I’ve had gas stoves all my life, and it’s never been a problem. And prior to this house, none of the ranges even had a hood.
“I’m gotten lab reports back that the black stuff is charred food particles stuck to soybean cooking oil.”
Which you’d get from an electric stove too.
Call your local city inspector and ask them how you should go about modifying the previous owners unpermitted construction and additions.
You sounds like you are way too familiar with the building codes. That is a tough world you live in. Good answer though.
