What is the minimum counter depth to install Ruby 4 Burner Pro-Sear 36″ with a wall behind the grill?

(I understand from the manual that the cut out is is 22", and that I need to leave at least 4" behind the back of the grill and the wall, but what I don't understand is how far the back of the grill extends behind the cut out. Because I don't know how far the back of the grill extends behind the cut out, I can't calculate the counter depth I need to leave 4" between the back of the grill and the wall.)

Hi - Measuring from the back of the grills FireBox it is 3-5/8" to the back edge of grill, and from the cut-out line its between 2-3 inches. The hood extends an additional 3" when Open, so is why you need a minimum 4" clearance. All this is illustrated on the grills Specification Sheet, you can download in the section box Downloads. Our office is open Monday 9AM Central TIme, at 512-487-5116 if you have additional questions.
