The discussion on “To Vent or Not To Vent” got me thinking more on my impending kitchen remodel.
I definately need and intend to install a stove vent. Currently, the range is somewhat near the original location (Interior wall). Backtracking, I have an old bungalow and the whole “original” kitchen is gone. Replaced by the previous owner.
There presumable was some sort of chimney vented stove at some point. The access INTO the chimney has been sealed but the access TO the chimney is still open. I’m unsure when this sealing took place. I am almost 100% sure the funrnace (oil fired steam heat) and the kitchen would be using same flue. I dont believe there is more than one flue thru chimney.
First, I am assuming that it would be a no-no for the furnace and a range vent to share the chimney.
Secondly, If above is OK by code, would it even be wise/ok to use this old chimney access for a range hood exhaust?
Would it be better to relocate the range to an outside wall? That would mean rerouting the gas lines.

As the warm vent gasses hit the cooler masonary flue, you'd be condensing water and grease into the inside surfaces of your flue...not to mention backdrafting issues.
Would it be better to relocate the range to an outside wall? That would mean rerouting the gas lines. Bingo.
Depending on the extent of your remodel, you could keep the present location and route the ductwork up the interior wall (or directly up into the ceiling), then run horizontally between the ceiling joists out to an exterior wall. Often times, however, that results in too many elbows and too many feet of ductwork, which degrades the effectiveness of the vent. If, as part of your remodel, you can move the appliance to a better location, now is the time to do so. The shorter the length and the fewer bends you introduce into the exhaust duct, the better. Use real metal ducting...not the pretend stuff. Seal all joints/seams/fastener penetrations well...not with duct tape. Mastic works well. Then wrap the duct with insulation. Consider introducing make-up air as well.
