recognized testing or inspection agency for venting gas appliances,
gas incinerators and solid or liquid fuel-burning appliances.
Field-constructed chimney made of metal and built in accordance
with nationally recognized standards.

A manually or automatically controlled device to regulate
draft or the rate of flow of air or combustion gases.
BACKDRAFT DAMPER (SHUTTER)A device which, when mounted in a duct or opening, permits the flow of air in one direction only. It is normally opened by the energy of the air stream but may be opened and/or closed by external mechanical means.

Part.
A passage for conducting the products of combustion from
a fuel-fired appliance to the vent or chimney (see also "chimney conductor"

in the primary combustion chamber and is designed to permit removal
of unburned residue and may be horizontal or inclined, stationary

provides uniform testing and examination procedures under established
standards, is properly organized, equipped and qualified for testing,

the listed products (see Appendix A).[1]
Materials which pass the test procedures (for defining noncombustibility
of elementary materials) set forth in ASTM E 136 when exposed to a
furnace temperature of 1,382° F. for a period of five minutes,
and do not cause a temperature rise of the surface or interior thermocouples
in excess of 54° F. above the furnace air temperature at the beginning
of the test and which do not flame after an exposure of 30 seconds.
Appliances which are so constructed and installed that all
air for combustion is derived from the outside atmosphere, and all
flue gases are discharged to the outside atmosphere.

Editor's Note: Appendix A is on file in the Township offices.
All wood-burning heating 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 one-quarter-inch asbestos millboard covered 28 gauge metal spaced
one inch or more from combustible surface, or manufacturer recommendations.
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 by a four-inch brick veneer, extending two feet
above and two feet beyond each side of heating appliance:
A.
All wood-burning equipment 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 circulating wood-burning appliance is 12 to 24
inches from a combustible surface, the surface shall be protected
by one-quarter-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-burning equipment is eight to 12 inches from
a combustible surface, the surface shall be protected by one-quarter-inch
asbestos millboard covered with 28 gauge metal spaced one inch or
more from the wall and floor to permit air circulation.
D.
Noncombustible material shall extend at least 18 inches beyond the
stove which ashes are removed from and at least six inches beyond
sides and rear.
E.
Where stove legs are at least 18 inches above a combustible surface,
a 24 gauge sheet metal or other suitable approved noncombustible material
shall be used.
F.
Where stove legs are between six inches and 18 inches above a combustible
surface, a 24 gauge sheet metal over one-quarter-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 not less than an inch thickness shall be used.
A.
Connectors serving wood-burning appliances shall not be connected
to a chimney serving other appliances. All stove pipes shall be equal
to or larger than appliance flue connector.
B.
All connector pipe shall be of a minimum of 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.
Crimped end of chimney connector pipe shall point toward stove. Adapters
may be used to permit crimped end to point toward stove.
E.
Single-wall connector pipe shall not pass through the floor or wall.
However, when necessary, a connector may pass through a partition
other than a fire partition under the following conditions:
(1)
Where ventilated type metal thimble is used and is three times larger
than the chimney connector.
(2)
Where a metal or burned fire clay 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 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.
(4)
All stove pipe shall be a minimum of 18 inches from combustible walls
and ceilings.
(5)
If stove pipe is 12 to 18 inches from combustible, the surface shall
be covered with one-quarter-inch asbestos millboard spaced one inch
from the walls or ceilings.
(6)
If stove pipe is nine to 12 inches from combustible surfaces, it
shall be covered with one-quarter-inch asbestos millboard with a 28
gauge sheet metal spaced one inch from wall or ceiling.
