All wood or coal burning stoves or appliances shall be at least
36 inches from all combustible materials. Where clearance is less
than 36 inches but more than 18 inches, the combustible surface shall
be protected by 1/4 inch asbestos millboard spaced one inch or more
from the combustible surface. Adequate space shall be provided to
permit air circulation. If clearance is less than 18 inches but more
than 12 inches, the combustible wall shall be protected with a four-inch
brick veneer wall extending two feet above and two feet beyond each
side. All other installation shall be as follows:
A. All wood or coal burning stoves or appliances that have circulating
devices shall be at least 24 inches from a combustible surface unless
the appliance has a rating for lesser distance from combustible surface.
B. If the distance of any circulating wood or coal burning stove or
appliance is 12 inches to 24 inches from the noncombustible surface,
the surface shall be protected by 1/4 inch asbestos millboard spaced
one inch or more from the walls with adequate one-inch spacing from
the floor to permit air circulation between wall and shield.
C. If the circulating wood or coal burning stove or appliance is eight
inches to 12 inches from the noncombustible surface, the surface shall
be protected by 1/4 inch asbestos millboard covered with 28 gauge
metal spaced one inch or more from the wall and floor to permit air
circulation.
D. Noncombustible floor material shall extend at least 18 inches beyond
the opening from which ashes are removed, and at least six inches
beyond the sides and rear.
E. Where stove legs are at least 18 inches above a combustible surface,
a 24 gauge sheet metal shall be used.
F. Where stove legs are between six inches and 18 inches above a combustible
surface, a 24 gauge sheet metal over 1/4 inch layer of asbestos millboard
or other approved noncombustible material shall be used.
G. Where stove legs are six inches or less above a combustible surface,
a four-inch hollow masonry pad should be laid or an approved noncombustible
surface of an inch thickness shall be used.
