Section 27-809
§ 27-809 Insulation and clearances. All accessible piping in habitable
and occupiable rooms carrying steam, water, or other fluids at
temperatures exceeding one hundred sixty-five degrees Fahrenheit shall
be insulated to prevent the temperature at the outer surface of the
insulation from exceeding sixty degrees Fahrenheit above the ambient
temperature. The openings for insulated piping through combustible
floors, walls, partitions, ceilings and other combustible construction
shall include clearance and insulation adequate to satisfy the
requirements of section 27-792 of article one of this subchapter. Where
accessible piping carries a fluid not exceeding two hundred fifty
degrees Fahrenheit and insulation would interfere with the functioning
of the system, such piping may be uninsulated provided sufficient
clearance is maintained from the combustible construction so that the
temperature limitation of section 27-792 of article one of this
subchapter is not exceeded, and all uninsulated piping shall be provided
with at least one-half inch clearance from combustible materials.
Section 27-810
§ 27-810 Firestopping. For requirements governing firestopping around
piping passing through floors, roofs, or fire separations, see
subchapter five of this chapter.
Section 27-811
§ 27-811 Insulation materials. All insulations shall be of
noncombustible materials. All coverings, vapor barriers and adhesives
shall have a flame spread rating no higher than twenty-five and a smoke
developed rating no higher than fifty. Adhesives and mastic finishes
shall be tested in sufficient bulk to produce maximum burning, and shall
be tested in accordance with reference standard RS 14-11.
