Todd, Is there a code section that disallows the use on branchlines? Tyco's XL-Trace installation guide indicates that it is UL listed to heat trace all parts of a sprinkler system (plastic and steel piping) except the main control valve.

I believe it is only for mains. An enclosure may be the only alternative, not knowing the dimension of the units involved. It would just need to be an insulated box, since we are enclosing a furnace and residual heat would probably keep the space warm. Sounds like a good pilot project.
