Tom- Your building seems appropriate for application of NFPA #13R, if its allowed in the locale; this would mean there is NO hose requirement, no need to debate where it comes out.
Might want to ask the chief where this guy learned review letter writing, since he obviously didn't learn the basics of "getting along" in kindergarten. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tom Duross Sent: Sunday, March 01, 2009 10:47 AM To: [email protected] Subject: RE: statistics I did that on a glycerin changeover on Cape Cod 2 summers ago. I used 1/2" ball valves with return bends to vent out the air. You'd want to get as much out on those as possible so the water doesn't creep past the heated room with the backflow and expansion tank. Tom What advantage is there to venting the air? Other than response time? Nothing fancy, a 1" ball valve; or an ITC-type set up if you want to get fancy and run it out, we don't always. Potter has an auto air release you could also use. George, You have a way to bleed the air off of the system at the high point? This sounds like a good idea. Cold you explain some more on how to make this happen?
