How to Install a Microwave Hood with Exhaust Fan - DIY

[@mauricelee7299]

The power of modern technology!!! First off, thanks to the creator of this video. This was published 6 years ago and it is still benefiting people to this very day, despite what appears to be some mistakes installation. Secondly, thanks to all the people in the comments ( some I assume are professionals in the field) who gave the much needed corrections on the installation. For me, one of the reasons I used to be doubtful about trying to do projects like this is because of fear of safety violations that could hurt me or my family. However, with all of the comments and many people saying the same thing about the correct material to use, ai feel confident that I can complete this project. Thanks to all.

BY FAR, the easiest step by step installation video. Thank you very much sir!

[@samadabdul1242]

Anyone watching, you should never use flex duct for microwave or range hood. Flex duct is for dryer vent. This will capture a lot of grease and will generate a lot more fan noise.

This is a great toaster oven replacement to the one I had for a few years. Easy to use, has all the right controls to cook my food how I would like. Looks great and doesn't take too much counter space. Very happy with my purchase.

[@sachaleia]

It's not as powerful as I thought it would be, but it works very well. kzbin.infoUgkxGjG43--gYqIoT4Xkur2PqCrtbKwTv2h6 There are three options to circulate air, and best of all a remote control for us lazy people. Installation was a breeze (no pun intended). It actually took longer to open the box then it did putting the side extenders on and sitting it in the window opening. It's a perfect alternative when you want airflow, but not the AC. Just might order another one for a different room. UPDATE: Bought another one like I said. They work great. Why not have two...

Round flex hose perfect solution with 2 end caps , you used at microwave vent. My roof vent is also, rectangular. Thank you for posting !

[@nidusa1]

please don't use flex duct for kitchen hood, besides not passing code inspection, it will hold grease. Use solid pipe, no flexible duct, no screws, and hoods usually need 6" or 8" or even a 10" duct pipe size for better air flow and less noise (see manual for appliance for their specific requirement). you can buy a converter that will allow increase from smaller duct size to larger. And that plug must be accessible, if you care about code/safety, move it over to left or right.

[@loboplumbing6258]

Good comments below you should first... Hire a Licensed individual who will install it as per local codes! or follow the installation manual since that is the minimum standard for all venting! Also like mentioned the flex duct shouldn't be used because its undersized, could trap grease, cannot be installed touching the wood cabinets, and cannot terminate under a wood overhang that would be considered fire hazard! Good job narrating the video Sir

[@FernandoRomero-u7i]

This is a great idea. I was thinking about running my duct through the roof since my stove is not sitting on an outside wall but this is a way better idea and that hole that you cut with a saw is pretty damn good for being cut with a saw!

Great video, I appreciate the help! But I second the flex duct - you're going to want to replace that with rigid metal ductwork that has a smooth interior to meet code & safety standards.

[@greid9349]

I know you say the rigid metal duct is needed to meet code and safety standards, but do you know the reasoning behind this? Just curious.

[@joeoconnell5706]

@@greid9349 Because of the ridges inside, flexible ductwork is more conducive to mold growth, it has a higher resistance to airflow, and the ridges also provide many more surfaces for dust and debris to collect.

Your microwave exhaust fan is rated at least at 300 CFM. Maximum flow through a 4" duct is 180 CFM. A 5" duct is a minimum acceptable for this installation.

[@eschrader]

Actually, the google says 400 CFM for a 4" duct. www.prolinerangehoods.com/blog/which-roof-cap-vent-hood/ Though I dont see any codes around the exact CFM.

[@deezee1570]

@@eschrader For a 4" diameter pipe to let 400cfm thorugh, the air needs to have the velocity of nearly 4600 ft/min which is 52 miles/hr. There is no way those little motors can push that much air. It's physics and there is no magic to it. If still in doubt, take any manual for an over the range hood, or a microwave with one, and see that the minimum pipe diameter is recommended.

[@charlesmirabal1671]

There are a lot of good/positives to take from this. But huge negative is that you are not using the correct duct and vent size. The microwave will say a min. 6" circular vent or 3 x 10 inch rectangle duct....Your fan is likely much nosier and will not pull as much air as it was designed to do. The most difficult part of this install is dealing with larger duct. If you go with the rectangular duct to fit the opening in the micro. then you will most likely have to completely sever a stud....which will require you to cut a large hole in the drywall and add a header and jack studs where the stud was cut out.

[@jzm6403]

A 6" duct is not needed in an application like this one. A 4" rigid pipe carries 400cfm. Most Microwaves are at or under that. I installed a 4" rigid pipe out the side of my house because of cabinet clearance on my ceiling. I have tall cabinets and simply did not have the space for a 6" pipe. I actually removed my microwave and installed a Hauslane Range Vent hood. It's rated a 500CFM but that's at full speed which is simply not needed. On low speed the fans are extremely quiet and move a tremendous amount of air. On the lowest setting the vent outside my house will mess up your hair in a heartbeat. I checked it with boiling water and actual smoke from cooking breakfast meat, like bacon and sausage. It pulls the smoke up immediately. I'm extremely happy with how it turned out. I would have installed 6" but simply didn't have the room.

Great job and thank you for this video. I have a different setup, however, I needed to replace all the ducting as well as our microwave because Starlings ripped off the exterior plastic vent covers and made a nest inside the ducting. We didn't notice until it was too late and now we're having to clean and sanitize everything. Its an insane mess. Thanks again!

[@jjcmafia]

make a cage out of 1/4 inch wire mesh to go over the vent without restricting the flaps of the vent. if you spray paint the mesh to the same color as the vent it will hardly be noticeable. I generally cut it into the shape of a large cross...then bend the tabs down 90 degrees and then back out at the bottom to resemble a top hat. Good luck with those birds.

"Good idea using duct tape everywhere" ha ha - tape is at the heart of all home improvement projects.

[@joshuatrager788]

So I m glad you got that in but unfortunately it's got a lot installation issues. First off you needed to move the outlet to the right. The venting is very undersized and is the flexible type. Needs to be 6" ridgid minimum, 7" recommended. Also ditch the crappy factory vent damper. I find most times when you connect your venting it gets bound in place. They make inexpensive ones that actually work you can install after the transition.

[@whutchyt]

May I ask why move outlet? Just learning before I hire someone to do.

[@joshuatrager788]

@@whutchyt Proper ridgid venting is going to totally obstruct the outlet. It should be ruffly located above where the cord comes out of the microwave. It can be on either side the vent.

[@kajalano3198]

Nice video and thanks for the time and sharing. One thing though...I do believe that you should only use 6 " duct for your Range Hood/MWave vent pipe. I recently did a similar project and 'tried hard' to go with 4", but every online resource I visited or Pro I spoke to me tried to veer me away from that. I eventually used to 6". Same principle except that the outside vent caps are HUGE. My understanding is that 4" is used for dryers, 6" for ranges.

[@mitchy02]

+Kaj Alano Thanks for your feedback! While I do agree that a 6" duct would be ideal to move the air, it is indeed quite large. I created a soffit above the cabinets and if I were to have done a 6" duct it would have been too big for what I had intended. The microwave still does a really good job at removing the air and that the 4" duct is handling it well.

[@BigBand1942]

[@ivaerak]

I've been busting my brains on to how to connect the pipe to the exhaust hole and now I find that TAPING IT UP IS SUFFICIENT??! Where have you been all my life

[@は私です彼の名前]

ivaerak this is the normal way to do this

[@ivaerak]

Thanks. In the end I used styrofoam instead, cause the tape wouldn't stick successfuly to the alufoil pipe. So I made little styrofoam cubical profiles and jammed them between the pipe and the hole, all around the diameter and now it's safe and firm, and without any air gaps. There are also reduction threads for pipes in hardware stores, but it wouldn't work in my case.

[@は私です彼の名前]

ivaerak ok, because I have to do this later today. You don't think duct tape would have worked? Do you have a pic of your styrofoam duct?

[@ivaerak]

T. B. unfortunately I don't since I don't live there, but I can sort of make a schematic drawing or take a pic tomorrow.

[@adiadi5948]

the only tiny change i would've implemented would be to put a bead of silicone on the inner flange portion of the outside before installing it, that way you get a full contact seal with the outer wall and partially inside the hole for a more sound mounting and sealing option but 👍 nevertheless!

[@faradpack]

absolutely agree, I just made a comment on that and also use of liquid drywall or cauck on the inside border as well, no roaches comin in from that crack

[@marcelobf85]

Just to make sure, with roof venting installed, no air should come out at the front of the microwave, right?

[@Dub-ry4cs]

Is there something behind the wall the microwave sits on? Is that why you didn’t just vent out that wall?

[@tinmania]

Thanks for the video. I am about to do the same thing, though I am fortunate that I can go right through cabinet since it is an outside wall. Strangely I asked at both Lowe's and Home Depot on what to buy and I got no help. I even asked if the register boot would work and the guy at HD said no and gave me a number of an air conditioning place to "build a box" in my cabinet (that I would then have to somehow connect to outside).

[@mitchy02]

A register box would also suffice. Any duct housing should work really. Just need to find the right size to accommodate your setup. Building a box is really just that. They would make a metal box to sit in the cabinet to catch the air and and exhaust it. HD or Lowes offers enough options to find something that would do the same job.

[@nickka2009]

at 5:55, you said you want to seal with tape to ensure no air flow outside of the area, and that all air goes straight into duct. what happens if there isn't a good seal, and i feel air coming out of microwave vent even though a duct was installed. my handy man didn't do a good job.

Just had to say glad to see your doing it yourself good for you. I know here it comes BUT You don't use flexible duct on exhaust must be rigid pipe. Using tape like you did wrong again tilting the fitting to accommodate the electrical not a good idea. 4" duct wrong again if you check your manual I'm sure they recommend 6". Do the math the square part of the fitting is most likely 10x3.25" 32.5 square inches - 4" dia area is only 12.56 square inches - 6" dia would be 28.26 square inches. Sorry but way to much wrong here to not say anything.

[@seanburns1278]

he is using an HVAC adapter. A proper over-the-range hood adapter is 7" round.

[@seanburns1278]

I will say, 4" is more ventilation than he had (better than recirculating)...but I agree. He cut his area for airflow by about 2/3rds when he used a 4 inch duct. And flex duct is the wrong way to go (at least it was not the flex dryer duct). Should be 7 inch round...though it seems 6 inch is getting more commonly used.

very good. I will try this myself when I get the energy and will probably use 4" solid duct across the top rear of cabinets, hiding it as much as possible, through a small closet and out. A longer path than yours. I may try to put in an additional exhaust fan at the outlet. Another option might be to go straight up, into the ceiling, then 90 degrees back out between the joists in the ceiling and out. I'm afraid though there might be electrical work there from the kitchen lights.

[@jzm6403]

I have almost the same setup but will be using solid tube instead of flex. I read many places that 4" carries 400CFM which is more than enough for this 300 CFM microwave. So many will say you MUST have 6" but this is overkill most of the time. The formula I read was 100 CFM for every 10" of stove size. Mine is 30 so I would only need 300CFM. 4" pipe is sufficient.

@@oscarochoarealtor Given the fact that the opening on top of the microwave is 3.25" * 10" (32.5 SQ"), just use the formula for area of circle: A = pi*r^2. With that you get a minimum diameter of just under 6.5". However I've seen most people say that 6" is sufficient.

People have pointed out the flex is illegal (and extremely dangerous), but it looks like you're working with 4 inch duct as well. 300 cfm, typical of a microwave, is the upper limit of 4 inch duct. Some laws put 300cfm above the upper limit. You're going to have a LOT of grease buildup in there, which WILL start a fire. Your flex duct is also on the outside of the boot so as the grease drips down, it'll pour out the sides into your cupboard, adding fuel to the fire.

[@jzm6403]

400 cfm is the upper limit of 4" duct, not 300. a 30" stove would be 100cfm for ever 10". So 300cfm is needed. His 4" pipe handles 400 cfm which is fine. He should replace the flex but many people use this. Even pro's from the range to the upper wall vent.

Can you use this with the stove to vent the air outside

[@bigcheetah987]

Just another comment about using the rigid/smooth ductwork as opposed to flex ducting. The reason for this is that flex ductwork will catch grease inside the it's creases over time, increasing the chance for fires in your ductwork. For that reason, it's against IRC M1503 (International Residential Code) to use it in range venting applications.

[@jlLeeification]

Yes but the exception is manufacturers instructions and there is foil duct that is fire resistant and rated from the manufacturer for kitchen vent

omgosh, use a long bit to go all the way through the wall to the outside as a pilot so you know it's all lined up. Also that foil tape feels so strong, but in 2 days it can fall off, iknow it seems crazy. use shurtape 181a-p/181b-fx.

Excellent 👏👏👏🤘🏻🤘🏻🤘🏻🤘🏻

What are you adding to cover the duct?

[@housepaintingtriforce]

Nice, very helpful video! whats the name of that stud finder? lol 9yearslater🤔

[@timyc2092]

Good job 👏🏻 man

[@LeMauKhien]

That flapping adapter in the beginning, did it come with your microwave? Didn't see it in your parts list. Thanks

[@trevorallen2274]

I have an LG microwave... It comes with one.

[@samiryounes9670]

great video and very helpful..thanks for sharing

[@blaztekaofficial898]

Very helpful 🫡

[@MAGAMAN]

Code calls for rigid metal ducting with a smooth surface. What you used will collect grease and potentially start a fire which you insurance company will refuse to pay for.

Awesome. Super helpful. I am trying a similar project, although the duct would have to go through an interior wall that divides the kitchen and dining area, and then across till it exits the home. I would say the distance would be 14 feet. Seeing the as duct would be exposed for 10 feet or so: Is there an option to install a larger duct over it, perhaps with an industrial look, that maybe makes it serve as an accent to the home, rather than an eye sore? Any suggestions?

[@mitchy02]

10 feet is quite a bit, but an industrial look would probably be the most appropriate.

[@froj.p6364]

+mitchy02 I hear if it's going to be so far it may have less ability to exhaust the air. But is there a way to install an external fan outside that helps pull the air?

[@froj.p6364]

+mitchy02 also can you use a solid pipe rather than a flexible one?

[@mitchy02]

You can use a solid pipe. Probably more recommended. I haven't heard of that. And you say your distance is 14ft? Your A/C ducts run further than that.

Good video really helps😀

[@rollinmckim4719]

Well Done! Thanks

[@Jarris2]

Did that adapter come with the microwave (made by manufacturer) or is it a standard part from lowes like the ducting?

[@tulipsjoshua]

How did you cover that vent hose....

[@inventoseideas3400]

This is the i want to do thanks mitchy for the video

[@TheMagedassad]

Can I install it without the flap that's connect to the microwave?

[@garretts91]

Great video although, microwave exhausts aren't made to deal with much backpressure. You should use a 6in pipe, minimum..Also, flex duct in a big no no... All the ridges will catch grease and it doesn't pass code. You need to use solid duct for kitchen exhausts.

[@victorvek5227]

Don’t ever use flexible duct, or semi-rigid ducting for this application. Always use rigid, galvanized steel ductwork.

[@AyubKhan-zi4go]

Very very useful. Thank you!

[@gtilapias]

Great video!

[@mitchy02]

Thanks for watching!

[@happychannel57]

How effective is this set up ? does it completely sucks up the smoke and odor from cooking? Ive been deciding whether to use my existing OTR or replace it with a full range hood. Your feedback would really help. Thanks!

[@mitchy02]

Vic Cruz I believe actual range hoods are more effective than OTR given that they can cover more area above the range itself. I would say (with no scientific backing) that it's 70% effective with my OTR. though, better than no exhaust. if you have the space and money I would opt for a range hood and separate microwave

[@MAGAMAN]

Microwave venting is very poor compared to a full range hood.

[@christopherdonlick9119]

residential code requires a smooth duct.

[@source2112]

is flex duct allowed by code ? or is supposed be rigid metal?

[@amandatrimoglie4209]

Exelente trabajo 👍 🏆
