Distance between gas oven and bottom of OTR microwave

Merry Christmas and happy holidays everyone. I had a question that I have searched to get a concrete answer, however it seems that the answers all vary from what I have read.

I noticed that the bottom of our OTR microwave gets warm from the gas stove. I read both the microwave and stove manuals and all it provides is the measurement of 30 inches from top of oven to bottom of the cabinet. When I measure this, mine is 36 inches. The top of oven to bottom of microwave is 18 inches.

Can anyone provide advise if this should be changed?

Thank you

You should change it not because of the distance, but because the BTUs the stove can generates overwhelms the OTR easily. The OTR is too weak for a gas stove.

If your gas stove is anything like mine, the requirement is 30” between the top of the stove and the bottom of the exhaust hood.

I am pretty sure you read it wrong. There is no reason for you to measure the distance between the cooktop and cabinet because it is not relevant. The otr microwave and exhaust fans all have different heights and there is no one height fit all.

I think measurement is to the bottom of cabinet because that determines the clearance between the range and OTR. I was surprised when I first read it in the manual, but it makes sense.

To op, obvious question, but do you use the fan when cooking? How warm are you talking about? For that stove, I believe 350 or 400 CFM is required for proper function.

You need a minimum 24" accessibility clearance from the side/top of an appliance where maintenance, repair, and replacement may be needed as per the gas code.

Yeah I have been using the fan. I’ve recently moved into this house and tested it while cooking and touching the bottom. It gets warm, but not to the point where I thought it would burn me.

Thanks for the info. Unfortunate that none of the cabinets can hold a microwave/have an outlet inside. Wouldn’t want to have it on the counter.

Measurements aside.

Of course it would be warm when cooking. What were you expecting?

If you are still worried about it, get the other Kitchenaid microwave, it’s slimmer and has higher cfm. Looking at pics, I would think it’s fine the way it is.

OTR microwaves/good aren't ever good for range hoods. I'd never want to have one over a gas cooktop. I had a KitchenAid OTR combo and it was awful. Nothing but problems and their support was atrocious. Hopefully OP doesn't go through my ordeal.

Google is your friend - the answer is out there. These might not be exactly right, but they might help you a bit. 18" is, I believe, too close by code.

And I also agree OTR microwaves suck. Is yours actually vented to the outside properly?

I cringe every time someone asks me to install one of those monstrosities. Getting any kind of proper duct seal is almost impossible. You sure don't want to be doing any stir frying with one.

Yeah. I felt like we had go with the combo unit based on space at my old house. Had I known how crappy it would have been I would have never installed it and just installed a proper hood.

I would personally rip that out and install a proper range hood. Then install the microwave somewhere else, even just on a counter.

Only 18" away, the heat is probably going to kill the microwave over time anyway. That's way too close for a gas stove.

That’s the whole point of these, to save counter space. OP or whoever put it in probably needed the counter space and hated counter clutter

When I installed my panasonic many moons ago, I believe 18" was recommendef by the manufacturer but this was for an electric range; gas is just to close imo. By code, its 30" from stove to the bottom of the cabinet. I don't believe the code makes reference to the bottom of a OTR microwave.

Then buy an electric range or increase the distance. 18" isn't enough

Agreed. OTR microwaves are the worse innovations. Not only do their designs make a strong blower impossible, but it's also dangerous to hold hot food above your head.

While I agree that OTR are the least desirable method of venting, I think if the installation guide required 30" from range to cabinet, and you've satisfied this, then the installation is fine.
