How to Vent a Range Hood on an Interior Wall

The following are the steps to take when you want to vent a range hood through a wall or roof.

Step 1: Disband the New Range Hood

First, you have to dismantle the hood into parts for easy installation and to avoid spoiling any of the parts. Detach the double filter and remove the covering beneath the hood; then remove the connecting pipe and keep it in one place.

Now take out the four-cornered pipe extension that is behind it. But it would be best if you employed a level of caution so as not to bend or disfigure any of the plastic or iron parts around the extension.

Step 2: Open a Hole

Open a Hole

Make a speck from the top of the kitchen units on the wall. Mark out one-eighth of an inch from beneath it and tug a straight line through the wall. With those two impressions, mark another rectangular shape of length 25cm and height 10cm

Create a hole for the pipe using the drywall saw; try to be as careful as possible, so you don’t hit any hindrance. In case you come across any, you could move the connecting pipe behind it back or forth until there are no hindrances. This process will help you avoid barriers when creating holes for range hoods.

If, after all these and it yielded no positive result, bring down the unit at the top of the pipe path, and put a rubric instead. Make a hole on the wall to expose the barrier, and then slash 15cm atop and 10cm beneath the route of the connecting pipe. Then construct the rubric using 2 5x10cm summers wrapped over 2cm lean plank spacer.

Ensure the rubric has a length that reaches the two ends of the barrier, and then create a twofold sill sheet by tying up the slimmer. When you’re done with the rubric, tighten a 5cm tall barrier trimmer to the entire size of the barrier in the wall. These trimmers should match the height of the barrier from top to bottom perfectly.

If the barrier trimmers don’t enter the hole, expand it, and tighten the twofold sill into the trimmers using nuts or screws.

Step 3: Put in the Rubric

Put in the Rubric

Tighten the rubric with a screw beneath the barrier dangling from the top. In the middle of the rubric and sill, fix in two small 5x10s to match the whole length of the barrier. Tighten them to the top and bottom of the barrier one after the other and cover the hole by placing fresh drywall over it.

Obscure the drywall ends using a drywall tape and seam mixture. Hang back the unit you brought down and make the pipe hole easily since you’ve taken care of the barrier. Create the whole from the interior wall to the outside and ensure the pipe can pass through it.

Step 4: Procedure for Installation

Procedure for Installation

The more technical aspect is finished, and once you’re done with that, the installation proper doesn’t take much time.

First, pass the electrical wires between the oval extension hole at the end of the range hood. Ensure you tightened the wire with a clamp, and if they are not long enough, add two cables of the same color using cable connectors.

Fasten the earth cable to the neutral. But ensure to do that before hanging the hood just beneath the kitchen unit and tighten correctly.

Also, ensure you fastened the nuts from the inner surface and to its place. Then move to the exterior walk and put the wall cap to conceal the patch entirely.

Put a steady drop of caulk on the extension of the wall cap. Afterward, push into the opening on the wall.

Look to ensure that the pipe on the wall cap fits into the end of the range connecting the pipe. If it doesn’t fit because of the excess length of the wall cap, clip with alloy snips, but if the length is not enough, add a duct to it.

Buy an extension duct and cut to size. Then fix it into the middle of the wall cap and connector pipe and fasten with a specialist duct tape. Round up the process by securing the cap to the wall with screws.

Step 5: Restore Electricity

Put the power on again and check if the hood fan fitting is working, also test the lights to ascertain if you made the right connection.

Check out the wall cap and ensure the flips dilate when the hood fan is working and shuts off when it not. Test the new install unit and check if your kitchen still has that awful odor, I bet you it won’t.
