Mich. Admin. Code R. 400.10547 - Heating devices and flame-producing devices
Rule 547.
(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
that provides at least 1 hour of 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 that penetrate this enclosure.
(2) In existing small facilities,
flame-producing-type heating devices and incinerators approved pursuant to R
400.71 et seq. shall continue to be approved with regard to enclosure or lack
of enclosure until the portion of the facility that contains the
flame-producing device is remodeled or the facility is converted. This subrule
does not abrogate requirements relative to maintaining doors and other safety
devices 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 that extends a
minimum of 16 inches out from the front, and 8 inches beyond each side, of the
fireplace opening.
(c) A
noncombustible face that extends not less than 12 inches above, and 8 inches on
each side of, the fireplace opening.
(d) A masonry chimney that is constructed
with approved flue liners.
(6) A heating plant room shall not be used to
store combustibles or as a maintenance shop unless sprinklered.
(7) A furnace and other flame-producing units
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
which 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 that bears 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.
