Fixing rangehood

I am trying to install my rangehood but when i took out my old rangehood i can notice the new rangehood has four screw slots on top roof. But as my kitchen cabinet is hollow from back so i need to drill side holes in rangehood. Any ideas how i can add support for the rangehood at the back so do not have to drill holes in the sides.

In the image below section 1 has two front screws goes it is fine but section 3 is hollow so screws can not be set there.

so need to drill holes on the sides ( section 2 ) to fix it. Is there any way i can avoid that. I am sure this would be standard things with kitchen cabinet but the rangehoods do not provide the option with side slot to fix screws.

Hello @DexterOz

You put the fixing screw through from the otherside/inside of the cabinet. If you are looking at the backwall of your rangehood cabinet thats where you need to drill through to get to your new timber fixing. Then on the cabinet on the left hand side of the rangehood cabinet you drill through that side. Please make sure to drill pilot holes for precise location of screws. I suggest watching a few youtube videos to give you ideas on timber fixings it should help and give you ideas.

Hi @DexterOz,

Let me tag some helpful members for you to see if they might be able to share how they would go about tackling this job: @Adam_W, @JDE, @ProjectPete, @redracer01.

I know @MitchellMc will also be happy to assist when he is back on the site on Friday.

Thanks,

Hello @DexterOz

Depending on the unit you purchased some range hoods specify where to make new mounting holes on the unit. Attached is a link for example : an install booklet for a Bellini range hood : http://www.belliniappliances.com.au/cooking/documents/CRHR6W01-F%20-%2060cm%20Retractable%20Rangehood.pdf

If you scroll down the booklet, it tells you possible new mounting points for installation. Your rangehood should have possibly come with an install booklet. The other method is to install a panel behind the empty space behind your cabinet. This is on the assumption that there is enough space at the back that it does not push the rangehood forward. Another method is to use hollow wall anchors to hold the rangehood from the back. Most rangehood have holes at the top so that you can screw from the underside and attach it to the bottom shelf inside the cabinet. Please post a make or model of your range hood so that we can better assess it. You may also call the manufacturer and ask them if drilling from the side of the range hood will not compromise the product. Looking forward to hearing from you. Good luck and stay safe.

Hello @DexterOz

Attached is the link to the user manual/install instructions for your rangehood https://www.westinghouse.com.au/cooking/rangehoods/wrr604sb/

It is at the bottom of that page on the westinghouse site. I suggest mounting it on your bottom shelf rather than making new holes at the side of the unit. You may have to adjust your shelf to have it at the correct height.

Cheers,

@redracer01 Sorry but just trying to understand what you mean to mount on the bottom shelf.Is it the thin wood shelf ( shown in image above where the comment is 1mm )

If i mount it on the bottom thin shelf sitting on the tile then the height for range-hood will not fit to cabinet height which is 175mm equal to rangehood. If i take that thin shelf out and then fit in rangehood mounted on tile support not sure if that will be able to hold the weight or not.

feeling stuck 🙁

Hello @DexterOz ,

Would it be possible to take a photo of your new rangehood ( top part ) to see if there are any mounting points. The holes you've circled yellow in your picture are the old mounting points and we will not be able to use them again. The mounting for your new rangehood will totally be different. I've attached a basic diagram of how it could possibly be mounted. Please note that this not to scale, Drilling new holes in your new unit might void the warranty, so I would not recommend it, unless the manufacturer says its ok to do it.

Cheers,

Red

P.S. My apologies I just realized I was looking at the bottom of the rangehood cabinet! It's not a shelf, in that case you will have to adjust the cabinet or add more panels to secure the rangehood in the provided space.

@redracer01Thanks for putting the details together. Yes it was rangehood cabinet. I have attached two images to give more clarity.

1) showing the front view for the rangehood cabinet

2) showing the bottom view camera facing towards roof which gives clear idea of issue shows the back part of the cabinet

3) Rangehood top view( 4 mounting screw slot)

Regarding the rangehood pic it is exactly similar with four mounting screw slots at the top panel ( as shown in the drawing you shared. ) Drawing is the correct description except in my case the cabinet is half the depth. I hope this gives the clear picture.

Your help is appreciated

Hello @DexterOz

Now that we can see it yes we will need to add a bit of timber to extend the bottom back of the rangehood cabinet. This will allow you to screw it in and not have to make new holes in your shiny new range hood.

@redracer01 Can you please help how can i do that extra support timber or mdf. How to put it in that tight space.

1 cut mdf piece to size to fill the space

2 cut two small temporary battens eg 42 x 19 pine. These are just to help you to align the infill piece. Hold these up against the underside of the existing front section of cabinet and screw in to the cabinets on either side (without going through them) to hold battens in place. The battens bridge the gap to the back wall of the cabinet and are an extension of the underside of the front cabinet.

3 cut two small pieces of the mdf (for temporary spacers) using same material as the infill piece (eg 16mm thick). You will lay them flat on the above battens within the gap behind the cabinet. This creates a rebate equal to the thickness of the infill piece so that the infill piece will be flush with the underside of the existing cabinet once it is screwed in.

4 cut two pieces of mdf (or other material) that will be permanently attached to your two side cabinets above the 2 and 3 temporary pieces above as backblocks for the infill piece. These don't need to be flush with the corners. Hold back block piece and the mdf spacer (3) in place on the pine batten, screw in with screws that don't penentrate the cupboards on each side, then remove 2 and 3. Now you have something to screw your infill piece to from below that is correctly positioned.

5 pre drill your infill piece before screwing it in to above.

if you can hold everything steady (batten pressed up against underside of cabinet, spacer and block pressing down on batten) you really don't need to screw the temporary batten in but it will probably be easier to do so.

Hello @DexterOz

Below is a suggestion of how you might do it. I suggest asking a handy man or builder if this is safe to do. Please refer to council rules and regulations in your area regarding rangehood mounting as each area and state is different and there may be strict guidelines on how to do it in your state. Please be informed and proceed with caution.

Cheers!

Thanks @Former Workshop member for the steps. I am beginner to am trying to put this together. really appreciate your help

DexterOz

Thanks @redracer01 this is very helpful for beginner like me for understanding where to put what. Yes with restriction in Victoria its difficult to speak or get a handyman. So trying to figure it out myself.

I can get this

https://www.bunnings.com.au/claymark-64-x-19mm-1-2m-standard-grade-dressed-pine_p8401490

I have measured the mounting screw slot on rangehood top is 4*4 from top left corner and right side which goes toward back of the cabinet.

What i am trying to still figure out is to screw that wood block to cabinet in slot 1, 2, 3 in image below.Sorry for my ignorance and bad skills

Thanks
