Mich. Admin. Code R. 400.4552 - Heating devices and flame-producing devices
Rule 552.
(1) In
large and secure facilities and all newly constructed and converted facilities,
flame-producing-type heating devices and incinerators shall be in an enclosure
providing at least 1-hour resistance to fire. Adequate combustion air shall be
provided directly from the outside through a permanently open louver. Fire
dampers are not required in ducts penetrating this enclosure.
(2) In existing small facilities,
flame-producing-type heating devices and incinerators approved under the
standards these rules replace shall continue to be approved with regard to
enclosure or lack of enclosure until the portion of the facility containing the
flame-producing device is remodeled or the facility is converted. This shall
not preclude requirements relative to maintaining doors and other safety
factors in proper working order.
(3) Electric heating shall be installed in
accordance with the manufacturer's specifications and shall be approved by a
nationally recognized, independent testing laboratory.
(4) Portable heaters and space heaters,
including solid fuel heaters, are prohibited.
(5) A fireplace is permitted if it is masonry
and has all of the following components:
(a)
An approved glass door shielding the opening. The door shall be closed at all
times except when a fire is being tended.
(b) A noncombustible hearth extending a
minimum of 16 inches out from the front and 8 inches beyond each side of the
fireplace opening.
(c) A
noncombustible face extending not less than 12 inches above and 8 inches on
each side of the fireplace opening.
(d) A masonry chimney constructed with
approved flue liners.
(e) The
chimney shall be visually inspected every other month while in use and cleaned
as needed, but not less than once every 12 months.
(6) A heating plant room shall not be used
for combustible storage or for a maintenance shop unless the room is provided
with automatic sprinkler protection. Flammable liquids or gases shall not be
stored in a heating plant room.
(7)
A furnace and other flame-producing unit shall be installed according to
manufacturer and test specifications and shall be vented by metal ducts to a
chimney which is constructed of bricks, solid block masonry, or reinforced
concrete, which has an approved flue lining, and is properly erected and
maintained in a safe condition. A bracket chimney is not permitted. This rule
does not prohibit the installation and use of any prefabricated chimney bearing
the label of an approved, nationally recognized, independent testing laboratory
if the chimney is installed and used in accordance with manufacturer and test
specifications and is compatible with the heating unit or units connected to
it. Only gas and oil-fired units may be connected to a prefabricated
chimney.
(8) All furnaces shall be
inspected on an annual basis by a licensed inspector. A copy of the inspection
must be made available to the qualified fire inspector or the department's
licensing authority upon request.
(9) A carbon monoxide detector, bearing a
safety certification mark of a recognized testing laboratory such as UL
(Underwriters Laboratories) or ETL (Electro technical Laboratory), shall be
placed on all levels approved for child care and in all furnace
zones.
