I am doing a kitchen renovation with new cabs and double wall ovens, two separate units. The oven instructions talk alot about proper support but don’t really say how to do it. This is a 33″ cabinet so there is room on each side of the oven. I thought i would run 2×4 supports down the four corners with 3/4″ plywood on top to hold the ovens. Could anyone give me a little guidance or maybe a picture.
Thanks

Two things - Enough support under to hold the weight of the appliance is one thing. You can calculate and or test it for double what the unit weighs for safety. That way the cabinet will not fall apart when aunt Tilda climbs on the door to get the thirty pound turkey out...
But the other major thing to remember is the anti tip bracket and how you will get to it! this is a major liability issue that too many of us have neglected in the past in this industry. Not a good idea to have the whole unit tilt out of the cabinet when Auntie sits on that open door

All the wall ovens I have seen are installed with screws on the face of the oven behind the door that go into the surrounding cabinet. This is the reason the oven won't tip out if the door is loaded when open. That, and the fact that the opening is rarely large enough to allow the pivot of the oven to go very far anyway. Today's oven door hinges would probably snap long before the oven pivoted out anyway.
As far as support goes, the basic cabinet built from 3/4" ply will be plenty strong enough to hold a standard wall oven. The opening for mine easily supports my 250 lbs without issue and is basically a dadoed 3/4 plywood box with face frame. BTW, I have a drawer below and a cabinet above the oven. I have yet to see a wall oven that weighed more than about 120 lbs. unless it's made by AGA. :-)
Reinforcing with 2x4s as you propose couldn't hurt, but will cost you some space for drawers, etc. below.
"the basic cabinet built from 3/4" ply will be plenty strong enough"I agree that a well built cab from 3/4" ply will be fine, but how many factory units fit that description?It has been a long time since I install a wall unit, but they did provide a bracket for anitip. probably just a liability thing for them, but there was no way I could have put it in and then installed the appliance hooked to it. Instead, I put in a block in the space above the oven unit, glued and screwed and located so that the oven could be slid in, but would never pivot to tip out.But the issue is not only whether it will tip all the way forward to fall on Aunt Tilda or the cookie crunchers under her feet. If it tilts even just a little bit, hot juice or sauce can slosh out of a pan or the roaster pan can slide forward and fall when it tilts a bit. Believe it or not, thousands of people are hurt this way every year in this country.

I just installed a wall oven several months ago in my kitchen and it came with two little brackets that attached to the inside of the case near the top and an inch or so inside. A piece on the unit engaged the brackets to prevent tipping, but they can be disengaged if you need to remove the unit.
The unit sits in a 3/4 plywood case which seemed more than sturdy enough. The installation directions (Sears Kenmore Elite) were fine, even for a first timer like me.
Yeah, every brand has some different detail for that. Some work and some don't.Final line is that the guy installing needs to be absolutely sure.

I installed a trivection double oven in Feb that weighed in at about 300#. Since I work alone, I had to build a platform and ramp in the kitchen to get the unit in place. I constructed a sub-base of 2x and 3/4" plywood. Worked well enough, and has yet to fall thru to the garage below.
