The only problem I see Thom is that I am sure we have all seen systems that were frozen but not broken so now we are back in the situation where the system is impaired without anyone knowing. I don't like it we do not use it at all.

The Owner, The Fire Dept. The Sprinkler Contractor The alarm company and more. True this would only be after a freeze and break, so the alarms sounded, but this doesn't seem a whole lot different than what we see all the time with owners,"Guessing that it will stay above freezing in a particular area" And then there is the contractors out, "Owner shall maintain space at 40'F" of course if your putting heat tape on the pipe, there's a pretty good indication that the owner doesn't intend to keep it at 40'F.

A break in the line at any point would render the system beyond that point inoperable and who would know? If the system didn't function at all, who would know? No way to insure operability. Craig L.

NFPA admitted that to their knowledge heat tape had never done fused a sprinkler and they were aware that there was a lot of heat tape in service on branchlines throughout the country. We just did a job where we used Chromalox products and learned a great deal. It is supposed to be around 100 deg max but under the worst conditions it will not exceed 150 deg. We are only using 3 watts per foot however and the temp varies accordingly from what I understand. We have used it once before and had no trouble whatsoever.

I currently have a 13R-2002 (metallic piped) project where the owner is looking to use the Raychem XL Self Regulating heat trace for supplemental freeze protection. The piping will be insulated as per the code but they want a belt and suspenders. Im looking for the code background as to why the appendix specifically prohibits branchlines - rather forceful language I thought to be in the appendix and not the code itself but oh well. The project natually is looking to heat trace the crossmains and branches up to the drops for the concealed pendants in the living space, hence my concern. The product is reportedly listed UL for Fire Protection piping but I am still awaiting all of that submission, in the mean time I need to educate myself as to the why's and why not's in the code and branchline prohibition. Thank you once again. Dave P.
