How to add a kitchen rangehood?

[avani1]

Hi there,

We have a very old model kitchen hood which doesn't have a vent out. All the cooking fumes are just blown into the house and the cabinets and roof are getting greasy and gunky as shown in the pictures below. We were thinking if the hood had a vent going outside then it would fix this problem. We have small vents on the wall near the window as shown in the photos. There is also a socket in the cabinet next the hood. Can we put a vent to the existing hood or do we need to replace then entire hood? Can you please provide a solution and if we need to change the hood, can you please give us some recommendations of what to buy.

Thank you!

Hi @AlanM52 

Thank you for your response. Here are photos of the window from the outside and the inside:

Hi there,

Window installation would be a eye sore and even harder than going through the brick wall, so I suggest the latter.

I will presume you have a strata tile and that brick wall does not fall under 'shared ownership of common areas, such as hallways and gardens'.

Flexible ducting-

We need 80mm/3" flexible ducting to cover that distance:

Can you measure-

From top of rangehood to top of cabinet.

Measure from there to end of last cabinet.

We then add (to be safe) 1M to that.

Please post that distance here.

Extractor vent-

Brick wall air extractor vent options.

Passive - no motor

240V motor

12V motor

I am still concerned what effect back pressure will have on extraction efficiency over that distance if we use a passive extractor vent.

240V vent would require electrician.

12V vent requires DIY skills.

Let's go with passive vent and see how it performs.

Question: Is there a power point near that corner.

Note: Both materials & tools will be updated as we progress through the job.

Materials-

80mm flexible ducting.

Paint Partner 48mm x 30m Silver PVC Duct Tape (0096426).

Tools-

Cordless drill.

Drill bit set.

Screwdriver set.

School compass.

Trojan 150mm Jab Saw (0191078).

Craftright 3 Piece Wood Rasp File Set (5760108).

Installation-

Rangehood:

You will need to try and work out how to remove existing one.

Follow the instructions to install the new one

Come back here if you get stuck at some point.

Ducting-

Measure, mark and cut a hole at the top of the cabinet large enough for the ducting to fit through - typically 90mm.

Scrib a 45mm circle and drill a series of holes around the inside of the marked circle.

Use jab saw to cut out the rest and half round rasp to to finish.

From the top feed ducting down onto rangehood outlet and tape if needed.

Leave the ducting on the cabinets with the other end hanging down over the edge.

In the next episode we will look at what's needed and how to install the extractor vent.

Cheers
