"Protecting Science - One Sprinkler at a Time" -----Original Message----- From: Morey, Mike [mailto:[email protected]] Sent: Tuesday, September 04, 2012 9:43 AM To: [email protected] Subject: RE: drum drip in cold spaces NFPA 13 2010 says: 7.4.4.4 Section drain lines and dry pipe system auxiliary drains shall be located in heated areas or inside heated cabinets to enclose drain valves and auxiliary drains for each section. That said we typically insulate and heat trace them with a supervised heat tracing, I don't believe what we use is actually UL listed for fire protection but we haven't had any issues come up from it.

However, they will be installed in the cold spaces (outside, not cooler/freezer). Do these need to be protected from freezing? Any suggestions how? Todd G.
