How To Install A Range Hood Vent Through Ceiling And Wall

How To Install A Range Hood Vent Through Ceiling And Wall

In this article we will discusses on, how effectively we can install a range hood through ceiling or wall. For different types of walls or ceiling contraction material installation process can be harder or easier. Like, brick walls or concrete rooftops are more tough to make a whole on it.

However,  if you have a concrete thick rooftop (3-5 inches); the better idea will be make the exhaust passage through the walls. So, the installation cost will be lower; and process will be more simpler.

There is no doubt on the essentiality of range hood as a kitchen appliances. Moreover, it not only vent out all the cooking contaminant from our kitchen; but, also help to maintain the kitchen environment more cooler.

There are three types of range hoods- under cabinet, wall mount & island. Under cabinet & wall mounted range hoods are easy to vent through the walls and ceilings; especially if you use the flexible duct pipes. For fixed duct venting the cost will be much higher as well as the procedure will be more complicated.

Note: To get maximum benefit must mount the range hood just above the cook-top or stove-top. Recommended height for installation 24 inches to 30 inches. Another checklist are range hood length must be greater than cooktop length; consequently, minimum suction power will be above 200 CFM for narrower kitchen & 350 CFM for medium size kitchen.   

Equipment & Material Needed For Installation:

All the types of equipment/tools are mentioned in the list that might not be required for everyone. Based on a variety of ceiling or wall materials, different tools are required. Like if your wall or ceiling is very thick 6” to 8”; then you need tool no 4, not 5.

Tools:

1. Manual drywall saw.

2. Electric Drill.

3. Screw Drivers and Nuts.

4. Electric drill with wider rounded saw blade for hole making

5. Reciprocating saw

6. Oscillator saw.

7. Measuring tape.

8. Pencil or marker pen.

9. Gloves.

10. safety eyeglass.11. Hammer (optional)

12.  Metallic / pensile compass

Materials:

1. Metallic duct pipe, flexible or rigid.

2. Roof Vent cap & wall vent cap/ roof or wall flashing.

3. Duct flashing.

4. range hood.

5. Aluminum foil tape

6. Roofing tar or silicone.

Types Of Range Hoods

Based On Construction

1. Under Cabinet Range Hoods:

These type of range hoods are mainly present in the narrower kitchen; installed just underneath your kitchen cabinet. The suction power widely varies between 200 CFM to 900 CFM. Few brands give you wall mount facility for installation. The under cabinet range hood inserts are very thin in height; moreover, it is lite weighted & specifically made for a smaller kitchen.

Most preferable ventilation are vent through interior wall.

2. Wall Mount Range Hoods:

The wall mounts exhaust hoods are most suitable for medium & larger kitchen. these kitchen hoods are directly mounted in the walls; consequently, consume larger space for installation. The shapes are widely varied, most common are pyramid-shaped; modern wall mount hoods are Italian curved shaped. Moreover, the exhaustion power is much higher than the normal range hood inserts.

Ideal exhaustion will be vent through the ceiling or through the wall.

3. Island Range Hoods:

Unlike wall mount, this beautifully curved range hoods are directly hanging from the kitchen ceiling. Most of the island range hoods chimney & base filter areas are separated with curved tempered glass. The suction powers are much higher & most recommended for the suspicious kitchen.

The only ventilation applicable here is venting through the ceiling.

4. Microwave Range Hoods:

Most common ventilation process of built in microwave range hoods can be either ductless or recirculating. Though it’s less effective as compared to above three range hoods. But, you can ventilate it through the walls.

Over the stove microwave with duct vent perform quiet effective.

5. Downdraft Range Hoods:

We don’t discuss this types of range hoods; because downdraft users don’t ventilate through the wall or roofs.

Based On Functionality

Convertible Range Hoods:

The convertible range hood has both types of facilities, whether you can use them as ducted or non-ducted hoods.

Ducted Kitchen Hoods:

Ducted range hoods are bridges with the duct vent pipe. Most households are using the aluminum flexible duct pipe. But, if you have a budget for investment, then you can go for a rigid duct. It’s a better option.

Non-Ducted Or Recirculating Range Hoods:

Non-ducted or recirculating hoods are fastened with carbon filters. This fitter sucks the vaporize cooking greases & reticulates the air & streams into the kitchen.

How to Install A Range Hood Vent Through Ceiling

The venting process of island range hood is slightly different from other two (wall mounted & under cabinet) kitchen hood. So, I will describe it separately.

Lastly, the flat ceiling hood installation& ducting process is a bit more different & difficult; so, our recommendation will be to hire a professional hood installer in this case. 

Special Note: If the roof is metallic or it made out of concrete tiles; we highly suggest you to call experienced or professional range hood installer to done the job.

1. Wall Mount & Under Cabinet Kitchen Hood Venting Through The Roof Installation:

The installation process is a bit easier; no need to un-mounting the range hoods, especially the wall mount vent hoods. For under cabinet vent hood you may need to dismantle the body parts, especially the filters, motors & grease panel.

Once; you pass out the duct pipe from the kitchen cabinet top portion; the duct-venting steps are similar to the wall mount one. In case of under cabinet range hoods, you just need to make a hole underneath the kitchen cabinet.

If you install it for the 1st time, take the dismantle range hood body; place it just underneath of the cabinet; and, complete the marking part properly. Make on bottom & top portion, to pass out the duct pipe. Most of the duct holes diameter is either 6 or 8 inches.

Once you have completed the process then you need to follow the bellow steps-

Special note: The steps I have described here is based on a home with the double ceiling. One hole on the inner kitchen ceiling & another on the roof top.

Step 1:

Mark the roof accurately, you can use pencil/ metallic compass for marking. The hole diameter will be exactly the diameter of the duct pipe.

Take a pencil compass, set the pencil & compass needle distances 3 inches (radius); moreover, you can use a measuring tape to set the radius distance. Draw a circle on white paper; perfectly pest it on the roof.

Step 2:

Our next task is making a whole on the inner ceiling for duct & we also need to make two whole for bypassing the electric cable. Similarly, try to make this hole perpendicularly above the wall mount chimney or cabinet top hole portion.

Step 3:

Now again we need to drill another hole on the top of the roof. Here use metallic compass & measuring tape to set radius distance 3 inches; Alternatively, you can also use singles or duct pipe as a template to make a circle mark on the roof.

There are several apparatus available in the market for roof drilling, based on the construction types of the roof.

So, for non-metallic or non-concrete roofs, you can use oscillator saw to drill this hole. If the rooftop is thicker, 4″ to 6″ thick, you also need to use the electric reciprocating saw for drilling.

Step 4:

Place vent/ exhaust cap & mark through the edges. Remove the wooden roof/ asphalt roof-top sheathing.

Mount the flexible duct pipe with exhaust cap singles. Use a clamp to tight up the duct pipe with vent cap singles. Now it’s a time to use aluminum foil tape to wrap on the joint portion.     

Step 5:

Places the vent cap drive the nails through the four edges of the vent cap. Consequently, use additional asphalt sheet to cover up the edges. Roof tar is very useful to prevent the water, to enter into your kitchen.

Step 6:

Now mount the flexible duct pipe with range hood. For under cabinet range hood, pass the duct pipe through the under cabinet hole to the range hood duct vent.

Must use aluminum foil tape to shield the duct pipe with range hood duct passage.

2. Island Range Hood Installation Venting Through The ceiling

Technically Island vent hood ductwork is easier; but, mount the whole unit on the ceiling is a bit more difficult. First, place the ceiling plate on the roof & mark the inner boundary & template of the circle.

Inner Boundary marking
Akdy Ceiling plate

However, few island hoods brand like AKDY ceiling plate doesn’t have inbuilt round duct on ceiling plate. So, it that case after drawing the inner boundary, you need to follow the Step No 1; which I have mentioned previously, for marking.

Ceiling Plate with duct hole

Now follow the pre-mentioned step 2. Once, you make the hole, then mount the ceiling plate. Consequently, install the “L bracket” on the four corners of the ceiling plate.

L Bracket installation

Again, follow the pre mentioned step 4 & 5.

Lastly, pull out the flexible duct pipe through the ceiling, install the chimney with support of “ L bracket ” & ceiling plate. Similarly, mount the duct pipe with island range hood vent passage & tightly wrapped with aluminum foil tape.

3. Flat Ceiling Hood Installation and Ducting Through The Roof

We exclusively suggest you call the professional for installation. This installation & ductwork is very much complex for a single person. Please check the video

How to Install A Range Hood Vent Through The Wall

For concrete roof holders, it’s the best option to vent out the range hood duct pipe through the wall. However, wall venting is only applicable for under cabinet & wall mounted kitchen hoods.

The horizontal duct mounting system will take place here, instead of vertical mounting.
