The stove itself will probably not protrude out far. About 1/2 inch of the side of our stove and the door protrude.

Yours looks nice. Do you happen to recall what the depth of yours is?

The 29 & 7/8" is to the outermost edge of the oven door handle and maybe the the front edges of the control knobs. Those are typically 2½" proud of the front of the mass of the stove, if not more. For aesthetic purposes, it is the mass of the stove, not the protrusion of oven handles and knobs that catch the eye.

April_love's installation looks standard. What you want is for the side openings on the oven door to be at least ½" or so beyond the face of cabinets. If the oven door gasket ever starts leaking heat, you won't be singing/charring the front edges of your cabinets.

Some Euro-stoves are not as deep as the standard for the North
American market, but you still need to have the edges of the oven opening proud
of the surrounding base cabinets. .

Generally. most concerns with slide-ins are a little different: (a) is the model designed to go flush against the back wall (as a freestanding range does) or do they have a bump out on the back that will require a filler strip between the wall and backsplash and the back of the cooktop part? and (b) how high are the countertops and will the stove legs adjust enough to let you lower the cooktop rim to the countertop?
