Can you vent a cooking range into a chimney?
I know you can't vent into fireplace chimney or one used for another appliance. Here's my situation.
We are doing a home addition/remodel in our cold-climate Vermont home, including moving the kitchen and adding a 48" Capital Culinarian (6 burners & Grill). The kitchen design has the range located on an interior wall against a brick chimney with 3 separate flues. The builder's "plan" is to vent the range into the flue that was previously used to vent a propane wood stove. The flue is separate all the way up through the roof and will be sealed from any use other than venting the range.
I have concerns as to whether venting this way will work? It'll be a long run to the top of the chimney...maybe 20ft (up through 2nd floor and out roof). Have heard conflicting things but seems that it can pass code as long as that flue is dedicated to the hood vent and nothing else.
Any advice as to the above, and as to what type of ventilation system/blower/CFM etc. would be best and affordable would be appreciated.
We are kind of stretching things with the high cost of the range (wife is skeptical but indulging my culinary inclinations) and don't want the venting to be the kicker that causes marital..hehem...discord!
Thanks in advance for your advice!
