Some kitchen hoods circulate air through a filter. Also called a recirculating or ductless hood, this kind of system can be less than efficient because it sends moisture and heat back. It is likely to replace an ductless hood having an exhaust hood which blows warm atmosphere that is cooking outside and through a downward-vented cap. It is a process that involves cutting a hole, adding the outside and ductwork vent cap, which, such as the mechanism within the range, is also known as a hood.
Out With the Old
Start the procedure by shutting the electricity off at the breaker box. Kitchen stove hoods have however if you are uncomfortable with wiring, consult an expert. To access the wires, remove the filters. You don’t need tools with this; tilt down them and slide them out. Based on the design, you may have to remove a metallic cover. With the cover removed, you need to see wiring. Double-check to ensure that the electricity is by employing a non-contact ion off. Wave it if it warms up, they’re hot. Disconnect the wires, when you are satisfied the electricity is off. Look for screws securing the hood on either side and into the cabinets above it. Put some support cubes beneath the hood to stop it once you remove the screws from falling.
Find the Hole
Run a cable/pipe sensor over the wall. Some stud finders possess this attribute built-in. You should be told by the sensor if any wires are found in the wall . It is unlikely that plumbing are in the area, but it doesn’t hurt to check for them. Avoid them Should you find pipes or wires otherwise take necessary measures when drilling or cutting. Choose the place for the hole when you are satisfied you may cut . Based on the design, it might require 6-, 7- or holes, or possibly a opening on the interior side. Check the manufacturer’s instructions.
Cut a Trail
Drill through the first layer of drywall employing an hole use a reciprocating saw, or saw for your design. This type of hole saw is large; use a drill with a chuck. Cut if the wall has lath older homes and remove it, too. Assess this hole’s path. When there is a stud in the way, angle the hole slightly to one side, or partly cut the stud to permit the pipe to pass . When a stud is right in the path and there is no way around it, consider out the outside soffit, and running the pipe through the cabinet and the ceiling. Include a header and the only solution would be to cut off the stud if that is not feasible. This may require patching it up afterwards and cutting on a hole in the drywall.
When cutting that is interior is done you are going to need some reference for the outside cutting . Drill a small, centered hole before you go outside. Go outside and use the hole saw to cut through the outside side, utilizing the hole with reference. Use the duct pipe you plan on installing if you are using a reciprocating saw, and trace a circle. Cut the outside circle with the reciprocating saw.
Blend It Flat
Exterior siding isn’t flat, meaning that the hood vent won’t fit flat. Remedy the problem with flange or an external PVC collar. It is a piece of inch thick with a pipe hole in the middle. Center it on the hole and then trace around it. Use an angle grinder cutting wheel to cut through the siding and then remove it. Leave the sheathing set up. Caulk around the cutout, set the collar in the hole and screw it.
Finish the Job
An kitchen exhaust outside hood includes an flange, but you might have to install ducting from the wall. You use 6-inch elbows, straight 6-inch ducting or a mix. This ductwork keeps the exhaust out of your walls and protects the walls from heat. You’ll secure the short length of duct into the downward-facing exerior hood flangeadd the outside hood. Before the downward-facing hood is flush with the PVC collar Twist the pipe into the hole. Screw the hood into the collar with self-tapping screws. Then you’ll secure the ductwork .
