Hi, I am having an issue with my cabinet maker about the clearance regulations for gas cooktop on a freestanding oven( see pics ) they keep saying it does not comply and they will not do the job. the distance from the gas burner to the back of the cooker is 130mm and if they leave a gap of 70mm that complies with the 200mm regulations and the cooker will overhang the 600mm bench by 70mm. they are still saying they will not do it as that does not comply. they want me to make my benches 800mm and leave a 200mm gap at the back to the entire cooker. does anyone have any pictures of a freestanding cooker infront of a stone splashback. any suggestions how to get them to see what I am wanting to do. i dont think they understand.
