I will have limited space behind the equipment. My hood requires a max 4″ underhang (low proximity backshelf).
A 36″ flat top I’m looking at is 25 7/8″ deep with a flue riser. I could have as much as 6″ clearance by hood requirements. That’s counting only the cooking surface. There’s no way I want my appliances sticking out that far!
The specs on the griddle don’t say anything about clearance. I don’t know if it’s a zero clearance unit, doubt it.
With a 4″ flue riser (think stainless backsplash, and sidesplash around cooking surface), and a stainless sheeted wall, I’m not expecting any hassle with clearance for my gas line hook up only.
So to answer the question, nearly zero clearance. If I get hassled, I’ll slide them out for the inspection, then, back in..
