6" seems a big waste of space. The Bluestar doesn't need that much. For any gas appliance, there is a requirement for a shut off valve on the gas line near the appliance. You might need a little additional space behind one of the drawers to accomodate that, if it isn't put low (in the area behind the kick plate, but it wouldn't need 5" and just part of the drawer back could be bumped in for it.

The gas line connection is 2" from the back of the range and the electrical is 1 1/8" from the back of the range. 3" at the back of the cabinet will provide plenty of space for them. Drawings are in the manual that I've linked to.

Here is a link that might be useful: Rangetop manual

My cabinet guy said he made the drawers the usual depth. I think he said 22" deep under my BS rangerop.

I have a CC rangetop. My cab maker made the two deep drawers under it the usual depth. The rangetop went in without issue. Then, months later when I was having my burners adjusted to run cooler, I found out the the gas regulator was not installed. When that was installed, my top drawer doesn't quite shut all the way. Next time my cab maker comes, he'll fix my drawer. It only sticks out about 3/4" or so. Six inches seems like a lot of wasted space.

Does the BS have a gas regulator?

Breezygirl, Cloud_swift, and Peke,

Thank you! Between the three of you, you have armed me with enough knowledge and real-life experience to have this conversation with my cabinet guy. I think he will do a great job on my cabinets, but he has a lot of "habits" that I am kind of breaking on behalf of GW. One more habit to break: No more 6" dead space behind drawers under rangetops!

One more related (probably dumb) question in case any of you read this: Does the back of a cabinet go all the way to the floor, or is there something similar to a toe kick on the backside of the cabinet?

Thanks again, Ott2
