specified, combustible surfaces will not overheat under normal and even abnormal operating
conditions.
NO PART OF THE INSERT MAY BE LOCATED CLOSER TO THE COMBUSTIBLE THAN THE
MINIMUM CLEARANCE FIGURES GIVEN.
9.1

at least 27" (686 mm) above the insert. At a height of more than 27" (686 mm), the shelf must
still have a maximum depth of 12" (305 mm).
