The installation guide for CPVC is quite clear that the pipe shall not be installed in combustible concealed spaces requiring sprinkler protection unless the protection in the space is provided by one of the specially listed heads for such an application. Simple enough.
However if one is sprinklering the concealed space with standard heads instead of the special listed heads it is not real clear what the required separation is to consider the pipe "not" in the concealed space. Sure there are criteria for a concealed installation, but that is specific to separation from the room below that is being sprinklered. In the experience of the forum members is it normal to use insulation tented over the pipe in as a method of treating the pipe as "not" in the concealed space, eventhough the pipe is still kind of in the concealed space? Or is the norm to use the concealed installation criteria eventhough that seems specific to separation from the room below that is being sprinklered. This question is not related to freeze protection concerns.
