There have been several threads regarding this topic. Many people install induction with drawers below and it's exactly what i plan on doing if I ever finalize a layout. Though not decided on the exact brand of induction; I do plan on getting one that has a smaller clearance underneath. Did you post this on Appliances as well? That might be helpful. You should have no trouble with this setup.

The installation guide for the Electrolux ICONÂ 36" Induction Drop-In Cooktop (E36IC75FSS) says:
It is not recommended to use drawer underneath cooktop. Empty space is needed for installation purpose.

[Note: the poor grammar is direct from the Guide]

It's just to make it easier to install, not b/c of functionality or safety issues. Take the drawers out and you have empty space! OK, it won't be as easy as to get underneath as crawling under, but it's really no different than a "regular" electric cooktop.

I called Electrolux Customer Service about this very issue and they stated that "no drawers underneath cooktop" is for installation purposes only. I told them their specs are confusing as they seem to indicate no drawers should be used at all. She agreed. Just make sure you have proper clearance underneath cooktop per specs.

Thanks

That makes a lot of sense.

I'm purchasing the Miele 36" induction and plan to put drawers under. I'm having a hard time deciphering the installation instructions but it looks like it requires 4 1/2" under the cooktop.

My Kenmore clone of the Electrolux has a glass top sitting on a metal frame that is configured to allow ventilation from above or below depending on how it is mounted. There is also a series of vents in the electronics housing at the back. My unit is presently sitting on some 2 x 4s where I can observe its behavior.

So far, I haven't heated enough stuff for long enough to induce it to operate its fan to push any significant air flow through the unit. However, assuming that I did, some air would be pulled from or pushed into the area under the unit. One would not want to seal that area, I think, but a drawer without a bottom on the drawer cavity may not be a problem as there would be air exchange with the rest of the cabinet and through leakage past the drawer faces or cabinet doors.

However, the more that is in the cabinet and the more tortuous the air flow path, the sooner the unit will warm up. This might have the effect of inducing a controlled power reduction or protective shut down. I specified my cabinets, not yet delivered, to have metal wire drawers so that there was maximum available air volume without making the cabinet useless.
