A permit shall be obtained from the Building Inspector to install a
freestanding woodburning stove or a freestanding fireplace in a private home
or any other structure, and such installation shall be approved by the Building
Inspector or Fire Inspector.
[Amended 7-12-1988]
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 five-eighths-inch
gypsum Sheetrock, Type X, rated Fire Code 60, 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 less distance from a 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 five-eighths-inch gypsum Sheetrock, Type
X, rated Fire Code 60, 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 five-eighths-inch gypsum Sheetrock, Type X, rated Fire
Code 60, covered with No. 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 stoves legs are at least 18 inches above a combustible
surface, a No. 24 gauge sheet metal shall be used.
F.
Where stove legs are between six and 18 inches above
a combustible surface, a No. 24 gauge sheet metal over five-eighths-inch gypsum
Sheetrock, Type X, rated Fire Code 60, 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.
A.
All stovepipes shall be equal to or larger than the appliance
flue connector.
B.
All connector pipe shall be of a minimum of No. 24 gauge
black pipe or heavier.
C.
All connector pipe shall rise from the stove toward the
chimney at least 1/4 inch per foot or more.
D.
The crimped end of chimney connector pipe shall point
toward the stove. Adapters may be used to permit the crimped end to point
toward the stove.
E.
Single-wall connecter pipe shall not pass through the
floor or wall. However, when necessary, a connector may pass through a wall
under the following conditions:
(1)
Where a ventilated-type metal thimble is used and is
12 inches greater in diameter than the chimney connector.
(2)
Where a metal or burned fireclay thimble is used and
the thimble is surrounded on all sides by not less than eight inches of brickwork
or equivalent fireproofing material.
(3)
When all combustible material is removed for a sufficient
distance to provide not less than 18 inches clearance on all sides of the
connector. Any materials used to close this opening must be noncombustible
insulating material.
(4)
When the section of the connector pipe passing through
the combustible material is replaced by a properly installed section of factory-built
insulated Class A pipe for solid fuels.
F.
All stovepipe shall be a minimum of 18 inches from a
combustible surface.
G.
If the stovepipe is 12 to 18 inches from a combustible
surface, the surface shall be covered with five-eighths-inch gypsum Sheetrock,
Type X, rated Fire Code 60, spaced one inch from the wall or ceiling, used
as a shield.
[Amended 7-12-1988]
H.
If the stovepipe is nine to 12 inches from combustible
surface, the surface shall be covered with five-eighths-inch gypsum Sheetrock,
Type X, rated Fire Code 60, with No. 28 gauge sheet metal, spaced one inch
from wall or ceiling.
[Amended 7-12-1988]
A.
Except as herein provided, all chimneys in every building
hereafter erected and all chimneys hereafter altered or rebuilt shall be constructed
of brick, stone or reinforced concrete or shall be Underwriters' Laboratories
listed Class A chimneys. No masonry chimneys shall have walls less than four
inches in thickness, and all chimneys shall be lined on the inside with fireclay
chimney tile set in portland cement mortar. The lining shall be continuous
from the bottom of the flue to its extreme height. No chimney shall be corbeled
out more than six inches from a brick wall, and such corbeling shall consist
of not less than five courses of brick, unless the chimney requires special
construction, and then any specially constructed chimney shall not be corbeled
out to such extent that the center of gravity of the chimney would be located
so as to endanger the structure.
B.
All chimneys shall project at least three feet above
the point of contact with a flat roof or two feet above any roof surface within
10 feet horizontally of the chimney. Portland cement may be used in the construction
of chimneys with the addition of not more than 10% by volume of hydrated lime.
No chimney in any building shall have wooden supports of any kind. Supports
shall be noncombustible and shall rest upon the ground or foundation walls.
Concrete footings under new chimneys shall be as hereinbefore specified for
concrete footings under foundation walls. All chimneys which are dangerous
from any cause shall be repaired and made safe or taken down.
C.
The fireback of every fireplace hereafter erected shall
not be less than eight inches in thickness of solid brickwork or aircell construction
nor less than 12 inches of stone lined with firebrick. When a grate is set
in a fireplace, a lining of firebrick at least two inches in thickness shall
be added to the fireback, or soapstone, fireclay or cast iron may be used
if solidly backed with brick or concrete. All smoke pipes shall enter the
chimney through a flue thimble or its equivalent such that the construction
shall make a firelight joint with the chimney-tile flue liner.
D.
All flue holes when not in use shall be closed with tight-fitting
metal covers. No wooden beams or joists shall be placed within one inch of
the outside face of the chimney or flue, whether the same is for smoke, air
or any purpose, except for hot-air flues for heating purposes. No woodwork
shall be within four inches of the back wall of any fireplace except if a
chimney is built such that the thickness from the flue line is eight inches
or more. Necessary woodwork may be placed against the chimney by using five-eighths-inch
gypsum Sheetrock, Type C, rated Fire Code 60, between and around the wood
so placed under the approval of the Building Inspector.
