Venting microwave through roof.

The old microwave did not. It appears when this house was built provision was made for venting out the rear of the microwave into the standard 2 4 wall up the cavity inside the wall then up through duct work in the attic through the roof. But an alternative worth considering if it does not make the vent run too long is to vent across the attic floor and down and out through a soffit or out through a gable end wall. I want to vent to the outside.

Venting through a roof vent or exhausting them in the attic could cause moisture problems and rot. Microwaves cannot be ducted into a common duct work. Microwaves are shipped from the factory to vent out the top vertically but can also be vented out the rear horizontally. Vent your bath and kitchen exhaust fans through the roof through a special roof hood.

I would like to use that path to vent a new microwave. An externally vented microwave mounted over a cooktop uses a fan to draw air through the microwave s vents and into an exhaust duct leading to the exterior of the building so most of the moisture heat odor and particulate matter generated by cooking goes directly outside. You would need to know what your local codes call for to use an existing chimney. Both smaller and larger vents than recommended decrease venting performance.
