Boilers, furnaces and stoves. SPS 375.30(1)
(1)
Protection of floor. Except as provided in
ss. SPS 376.13,
377.31,
378.09 and
379.20, every existing boiler, furnace or oven shall be placed on a fire-resistive floor projecting at least 2 feet on all sides. Such floor shall also be provided for every coal, wood, or oil stove or range which is more than 16 square feet in horizontal area or which has a flame at the bottom. If any such floor rests on or is in contact with any combustible material, then the fire-resistive floor layer shall be at least 3 inches thick and shall be hollow, with air spaces running horizontally through the same. The air spaces shall be open at both ends and shall be so placed that air can circulate through them; their horizontal area shall equal at least one-half the horizontal area of the fire-resistive slab.
SPS 375.30 Note
Note: The purpose of these air spaces is to permit air to circulate through the fire-resistive slab and keep down its temperature. When a range or a heater rests on a solid layer of brick or concrete, it has been found that after several months the heat strikes through to the wood below. Many fires have been caused in this way.
SPS 375.30(2)
(2) Air spaces. The air spaces may be secured by using hollow tile placed end to end; or by imbedding wrought or sheet iron pipes (say 3 inch diameter or larger) in a layer of concrete. The air spaces should run parallel to the short dimension of the slab.
SPS 375.30(3)
(3) Fire-resistive floor layer. If the stove, range, etc., is raised at least 6 inches above the floor and such air space is not enclosed, then the fire-resistive floor layer may be reduced to not less than 2 inch solid thickness, without air spaces, provided it is covered with sheet metal.
SPS 375.30(4)
(4) Coal, wood, oil stove. Every coal, wood or oil stove or range not more than 16 square feet in horizontal area and not having a flame at the bottom shall, if placed on a combustible floor, be raised at least 6 inches above the floor, and such air space shall not be enclosed. Such floor shall be protected with a stove board of sheet metal or asbestos, projecting at least one foot on all sides.
SPS 375.30(5)
(5) Gas stove. Gas stoves shall be protected as above specified, except that:
SPS 375.30(5)(a)
(a) A 3 inch solid fire-resistive floor layer, projecting at least 6 inches on all sides shall be sufficient protection if the stove has a false bottom at least 3 inches above such fire-resistive floor; and
SPS 375.30(5)(b)
(b) If the stove is less than 16 square feet in horizontal area and has a false bottom at least 5 inches above the floor, no fire-resistive floor shall be required.

Protection of walls and ceiling; repair; fireplaces. SPS 375.31(1)(1) Except as otherwise provided in
s. SPS 375.30, every combustible wall, partition or ceiling which is less than 24 inches distant from a boiler, furnace, oven, stove, or range, shall be protected with at least
1/
4 inch asbestos board covered with galvanized sheet metal, or with equivalent protection as specified in
s. SPS 375.11, or shall be protected with a metal shield with at least 4 inches air space behind the same, except as provided below. If the wall, partition, or ceiling is less than 12 inches distant from the boiler, furnace, oven, stove or range, then the woodwork and studs shall be cut away and replaced with incombustible material; or shall be otherwise protected as required by the department or the fire department.
SPS 375.31(2)
(2) The above distances may be reduced one-half in the case of stoves and ranges less than 16 square feet in area, and also in the case of gas ranges of greater area if proper insulation is incorporated in the back of the range.
SPS 375.31(3)
(3) The top of every boiler, furnace or oven, shall be covered with asbestos, sand, or other heat resisting material, or the required distance above same shall be increased 100%.
SPS 375.31(4)
(4) All cracked, broken or otherwise defective stoves, furnaces and boilers, shall be repaired forthwith, and made safe, or shall be replaced with new ones.

1/
4 inch asbestos.
SPS 375.32 Note
Note: The double thimble is of no value unless it is kept free from dirt. The best protection is a casing of solid masonry, with 1/4 space between the masonry and the pipe.
SPS 375.32(3)
(3) No part of any smoke pipe shall be placed nearer to any combustible partition or wall than the diameter of the pipe, nor nearer to any combustible ceiling than one and one-half times the diameter; but the above distances may be reduced by one-half, if the wall or ceiling is covered with not less than
1/
4 inch asbestos board covered with galvanized sheet metal, or with equivalent protection as specified in
