From the belly of the beast - kitchen venting


Am trying to plan for vent fan in my kitchen. The problem is the kitchen is situated at in the middle of the floor plan (Old building, back porch was converted to a room, isolating the kitchen from the outdoors.

As I see it, there are a few options

-The old chimney is used to vent the gas boiler and water heater. Can i punch into that for kitchen ventilation, or is that just asking for trouble?

-Straight up. Its a first floor unit in a two story building. It'd be about 20 feet to get through the roof. The walls will not accomodate a huge vent pipe.

-Something else? If I can vet far enough, there is a skylight through which I could run the vent to the roof without a huge amount of difficulty. It would be a 40 foot run at least though.

Eager to get this done, made some grilled chicken wings the other day and it looked like a 1700's battlefield.

Thanks in advance

If your chimney gets blocked for any reason, all the carbon monoxide would go where?
20 ft is not that bad, how big of a pipe can you get in the wall?
How would you permanently rig up a vent through a skylight?

You can not for many reasons punch into the chimney unless you want to kill your family. The forced air into the chimney space will prevent the gas appliances from venting correctly. Also you will be filling your chimney with grease which is obviously a fire hazard. Vent properly according to the specifications of the unit.

Can you go down, thru a crawl or basement?

I agree that touching that venting is asking for a whole lot of trouble.

I would try to go straight up the wall. But things get in the way sometimes.
Is it not possible to build a bullhead across the wall of the other room to get outside?

A drawing of the floor plan might help---also a sketch of the second floor joist orientation.

Sometimes the venting run is a nightmare---

What's on the other side of the range wall in the new back room (old porch)? A closet can often provide a punch through/cover up point, then up through joists if you can't do it directly from kitchen ceiling itself. Or, since it use to be a porch, maybe through and up above its ceiling to outside of the new room. Note code on where exterior vents may be placed for safety reasons (e.g. chimney). So much depends upon the way the joists run and size of your new ductwork. Lower BTU's of cooktop may translate into lower CFM/duct size on vent issues.
