The blazemaster technical handbook states that cpvc pipe and fittings are not approved for installation in combustible concealed specs requiring sprinklers, as referenced in nfpa 13 unless protected by sprinklers specifically listed for this application. Further on down, the handbook talks about use of a CC1 and CC2 combustible concealed space sprinkker.
We all know that concealed spaces of combustible construction are required to be protected by sprinklers unless an exception is met, which there are plenty. My question is this: the use of non combustible insulation shall not require sprinkler protection per 8.15.1.2.7. However, if this exception is used, is the use of cpvc pipe still permitted since we are using an exception in 13 that omits the use of the special sprinklers called for in the combustible concealed space section of the technical handbook?
