Interior design help for everyone.
The National Building Code (of Canada) requires non-combustible material 18” x 18” to the left and right and 30” high. This includes the wall behind a range, a blower unit in a wood framed hood, but does not include a (metal) vent-hood.
The manufacturer will dictate the non-combustible zone for gas ranges and that 18” x 18” zone to the left and right may increase to (18” Left + Range Width + 18” Right) x 30” high.
Another hint - Look in the installation manual of the stove you are specifying. It will show/tell you what the manufacturer’s requirements are. Quite often they are the same as the National Canadian code.
