The 2 pipe shall be installed utilizing listed support devices for thermoplastic sprinkler piping or other listed support devices which mount the piping directly to nominal 2 in. wood blocking or listed support devices for thermoplastic sprinkler piping which offset the pipe a nominal distance
of 1 1/2 in. from the joists.
NOTE:
Use of TYCO CPVC Pipe and Fittings is limited to basements where the quantity and combustibility of contents is low and fires with relatively low rates of heat release are expected. For additional information re- garding the assembly and installation of TYCO CPVC Pipe and Fittings refer to the manufacturer’s installation instructions.

Combustible Concealed Spaces (UL)
TYCO CPVC Pipe and Fittings are not approved for installation in combustible concealed spaces requiring sprinklers, as referenced in NFPA 13 unless protected by sprinklers specifically Listed for this application. Although NFPA 13R and 13D permit the omission of sprinklers from combustible concealed spaces, TYCO CPVC Pipe and Fittings can be installed in these areas when protecting residential occupancies according to these standards.
For installations where sprinkler pipe runs through an attic space that requires sprinklers per NFPA, CPVC piping shall be protected in order to meet the requirements of its UL and C-UL Listings. Additionally, the authority having jurisdiction shall be consulted prior to any installation of CPVC in attic spaces requiring sprinklers. Protection methods and requirements may vary by jurisdiction and are subject to interpretation.
