elevate said appliance at least 18 inches above a combustible floor
surface, a protective covering of twenty-four-gauge metal shall be
placed under the appliance.
B. Where the supportive members are designed to elevate the appliance
a distance of between six and 18 inches above a combustible floor
surface, a protective covering of twenty-four-gauge sheet metal clad
over one-fourth-inch-thick noncombustible stoveboard shall be placed

C. Where the supportive members are designed to elevate the appliance
six inches or less above a combustible floor surface, a four-inch-thick
