CSD-1 applicability question
I had understood that CSD-1 did not apply to boilers smaller than 400 MBTU/hr. As I start to read http://archive.org/download/gov.law.asme.csd-1.2009/asme.csd-1.2009.pdf I see CG-130 excluding really large boilers and swimming pool heaters, but CG-140 goes on to lay out a somewhat complex series of conditions for listed boilers under 400 MBTU/hr.
CG-140 (1) requires two things:
Compliance with all of part CW
Is this something we need to verify on a case by case basis?
Compliance with two specific paragraphs of CE-110
CE-110 (a) requires a lockable disconnect "at the boiler" and an external boiler room shutdown. The first aligns well with both NEC and mechanical codes. The second seems to imply that I need to include a solenoid-operated gas valve (as interlocked with kitchen hoods) on the plant main?
CE-110 (i) apparently forbids self-resetting controls after the primary?
