How to install a new kitchen fan vent

Vent through the roof

Run duct work through the cranium, so attach the stove vent to a roof cap.

If you desire to replace the range hood and exhaust fan higher up your stove and vent information technology to the exterior, and the stove is against an interior wall, yous take several options. But the dominion of thumb is to route it the shortest and straightest path to daylight. That manner, you'll become the best airflow and the least amount of grease buildup for your kitchen fan vent.

From the within wall of a ranch house (one level), that route usually means going upwardly through the attic and out the roof. You could also get up into the cabinet higher up the stove—then horizontally to the closest outside wall, either through the cabinets or in the area in a higher place the cabinets. Unfortunately, running the vent that way eats up valuable cabinet space, and it can exist tricky to install, especially if you attempt to run it in the soffit expanse because of obstacles.

Whichever road yous choose, brand sure the total duct length doesn't exceed the fan capacity. The owner'southward manual will usually tell you specifics on duct sizes and lengths. First, plan your road. The safest way to check the attic directly to a higher place the stove is to chuck an 18-in. section of straightened glaze hanger into a drill. Loosely agree the wire and direct it through the ceiling drywall approximately where your vent pipage will get.

Go upwards in the cranium, observe the coat hanger and push insulation aside to make certain there are no joists, electrical wiring or other building materials that might block a 6-in. pigsty. Then examine the roof directly above the wire to make sure there's room to install a roof vent. Drop a plumb bob down from the roof to the wire so you can notice the approximate roof leave location. You may have to shift the vent position several inches to avoid ceiling and roof framing.

Back in the kitchen, mark the cabinets and cut holes for the ducts. Attach all ductwork, then go upwardly to the cranium and reposition the plumb bob so it drops straight into the middle of the pipe coming up from the kitchen. Cut the hole for the duct, attach it, and then install the roof cap.

If you live in an area where frost occurs, add an insulated duct sleeve to the portion of pipage in the attic. Spiral the ductwork together with 1/4-in. sheet metallic screws and seal the seams with aluminum-faced duct tape (not regular, cloth-backed duct tape).

Finally, install the hood. Attach the transition duct to the hood and make sure the damper flap operates freely. Lift the hood into place and attach it to the wall. And so caulk effectually the vent pipe where it enters the ceiling.
