exhaust fan

RJ_4

A relative replaced there electric range with a gas stove, they currently only have the exhaust fan on the upper microwave as a exhaust that exhausts through a filter and back into kitchen, I told them that they need an exhaust fan and hood installed to exhaust to the outside, Is this correct

Depends on your local code. Here in NYS outside exhaust is only required if the gas range has an open grill/broiler unit. If it's just the standard burners then no. You also need to look at the appliance itself as some have built in downdraft ventilation built into them.

As has been said code varies, however if it was me I'd never consider a stove of any type without a good outdoor vented fan.

I lived in an apartment for 7 years with a poorly outdoor vented exhaust through the microwave and it was awful. Now, I have a 440CFM exhaust hood piped outside and I can even clean my oven without opening windows, it blows 100% of the smoke outside..

Not only that, but with a gas stove it ensures plenty of O2 for the burners and any CO that may be created will be vented.


Please, regardless of code, have a quality outdoor vented exhaust system installed, even through the microwave if need be. The microwave likely offers both options.

Don't forget to consider the impact an exhaust fan may have on the draft of you heater/water heater. You don't want to start pulling products of combustion down the chimney and into your house.

Hi, Read this: http://newscenter.lbl.gov/2013/07/23/kitchens-can-produce-hazardous-levels-of-indoor-pollutants/ then you'll want to put in a good hood and exhaust pipe!
