Current through Vol. 24-12, July 15, 2024
Rule 217.
(1)
					 Heating shall be by a central heating plant, a permanently installed electrical
					 system, or a sealed combustion unit or units mounted on an outside
					 wall.
(2) A central heating plant
					 shall be installed in a 1-hour-fire-resistant enclosure that includes a
					 B-labeled fire door and frame assembly in any interior opening. Combustible
					 ducts shall not be used inside of, or penetrate a required fire-rated
					 enclosure. Air for proper combustion shall be drawn directly from the outside
					 of the building by a permanently open louver, and approved mechanically
					 operated automatic louver or noncombustible duct. A fuel-fired central heating
					 plant requires fire damper installations where ducts penetrate a 1-hour fire
					 rated enclosure except where the heating plant complies with either subrule
					 (6), (7), or (8) of this rule.
(3)
					 A permanently installed electrical system shall be either baseboard or panel.
					 It shall be listed by a nationally recognized independent testing laboratory
					 and installed according to the manufacturer's specifications.
(4) In new construction, additions,
					 conversions, or remodeling, roof-mounted, fuel-fired heating units shall be
					 separated from any building that is used for camper sleeping by at least
					 1-hour-fire-resistive construction. In all camper-occupied buildings, whether
					 used for camper sleeping or not, roof-mounted fuel-fired heating units shall be
					 installed in accordance with the manufacturer's specifications utilizing
					 industry-recognized methods and materials.
(5) A sealed combustion unit shall be
					 approved by a nationally recognized testing laboratory, mounted on an outside
					 wall, properly vented, and installed according to the manufacturer's
					 specifications.
(6) In new
					 construction and conversions where buildings are used for sleeping and where an
					 electrically powered smoke detection system is not required, there shall be a
					 duct smoke detector installed ahead of the fresh air intake in the return air
					 duct of the system so that upon smoke detector activation, the fan to the
					 heating unit will shut down.
(7)
					 Buildings used for sleeping and requiring an electrically powered fire
					 detection system shall have the system connected to the furnace so that
					 activation of the fire detection system will shut down the fan. This is not
					 required if either of the following provisions is complied with:
(a) Approved fire dampers are installed at
					 all duct penetrations in the heat plant enclosure.
(b) The heating system has a duct smoke
					 detector installed ahead of the fresh air intake on the return air portion of
					 the system, as permitted in subrule (6) of this rule, so that activation of the
					 detector will shut down the fan and sound the building fire alarm.
