Need Help Replacing Slide-in Stove/Range with Induction Cooktop
Trying to replace existing Range (Slide-In):
(Dimensions of 31'' x 21 1/4'')
My current Granite Cutout is:
Width of 20.5" X 29.7 Length
*Not a Square - the front is opened
Installation guide with this induction cooktop says that the dimensions I need is WIDTH OF 19 7/8 - 20" and LENGTH of 28 3/4 - 28 7/8".
1. Considering that the installation guide states that the induction cooktop glass will NOT sit on the granite countertop (the weight is supported by 4 brackets below that is drilled to the cabinetry/granite), can I still use this cooktop with the given granite cutout? The granite cutout is currently ~ 1 inches > MAX recommended on length and 0.5" > MAX recommended width. It doesn't seem like an issue considering the dimensions of the glass (overall dimensions specified above) covers the hole and the weight is being held by the brackets?
Because I am replacing a slide-in Stove, I do not have a front granite. It says that I should have 2-1/4" of granite at the front. What is the purpose and again I would ask is it necessary or is it purely for looks/aesthetic reasons? Weight is being supported, again. Will it look crappy if there isn't granite in the front? I would venture to guess a lot of people have replaced their slide-in electric stoves with cooktops such as this, what are your experiences?
3. To mount the 4 brackets (shown in the installation guide), it seems that I would have to drill and tap the brackets into the granite or supporting frames. I looked and there isn't anything currently there, just granite, so I was wondering, is it difficult for me to drill (or tap?) holes into granite?
Thank you to any one that can help assist or have experience.
