If direct heat is used, the baking compartment of the oven shall be cut off from the fire chamber and smoke flue by a tight noncombustible partition, and provisions shall be made to keep the flame at such distance from such partition as will preclude the possibility of igniting the fumes in the baking compartment.

The walls and ceiling of every metal oven shall consist of an inner and outer shell of metal not less than three-eightieths-inch thick, with riveted or welded seams and joints, secured to a rigid framework of suitable iron or steel shapes. The inner and outer metal shells shall be separated not less than one and one-half inches, the space between being filled solid with fused noncombustible insulating material not less than one and one-fourth inches thick.

   Brick Oven Construction. Every brick oven shall have walls and ceiling at least four inches in thickness and shall be provided with a metal door not less than five sixty-fourths inch in thickness.

   Open Ventilation and Relief Covers. Every japanning or enameling oven shall have a vent pipe of iron or steel, not less than one-thirty-second inch thick with riveted or welded seams and joints, or formed of a compressed mixture of asbestos fiber and portland cement or as provided by Chapter 13-152 of this Code for smoke flues and chimneys.
