How to install a new kitchen fan vent

Vent through the roof

Run duct work through the attic, and so adhere the stove vent to a roof cap.

If you want to supplant the range hood and exhaust fan above your stove and vent information technology to the outside, and the stove is against an interior wall, you have several options. But the rule of pollex is to route it the shortest and straightest path to daylight. That mode, y'all'll get the best airflow and the least amount of grease buildup for your kitchen fan vent.

From the inside wall of a ranch business firm (one level), that route usually means going upward through the attic and out the roof. You lot could also go up into the chiffonier above the stove—so horizontally to the closest exterior wall, either through the cabinets or in the area above the cabinets. Unfortunately, running the vent that way eats up valuable cabinet infinite, and information technology can be tricky to install, especially if yous effort to run information technology in the soffit expanse because of obstacles.

Whichever route you choose, brand sure the total duct length doesn't exceed the fan capacity. The owner's manual will unremarkably tell you specifics on duct sizes and lengths. Get-go, programme your route. The safest manner to bank check the attic straight above the stove is to chuck an xviii-in. section of straightened coat hanger into a drill. Loosely hold the wire and direct it through the ceiling drywall approximately where your vent pipe will go.

Go upward in the attic, notice the coat hanger and push button insulation aside to brand sure at that place are no joists, electrical wiring or other building materials that might block a six-in. hole. And then examine the roof directly to a higher place the wire to make sure there'south room to install a roof vent. Drop a plumb bob down from the roof to the wire then you tin observe the approximate roof exit location. You may have to shift the vent position several inches to avoid ceiling and roof framing.

Back in the kitchen, marker the cabinets and cutting holes for the ducts. Adhere all ductwork, then go up to the attic and reposition the plumb bob so it drops straight into the centre of the pipe coming upwards from the kitchen. Cutting the pigsty for the duct, attach information technology, so install the roof cap.

If yous live in an expanse where frost occurs, add together an insulated duct sleeve to the portion of pipe in the cranium. Screw the ductwork together with 1/iv-in. sheet metal screws and seal the seams with aluminum-faced duct tape (not regular, fabric-backed duct tape).

Finally, install the hood. Attach the transition duct to the hood and make sure the damper flap operates freely. Elevator the hood into place and attach it to the wall. Then caulk effectually the vent piping where information technology enters the ceiling.
