Safety Valve Installation

[omerada]

I have found it necessary to install two safety valves in my boiler, but due to space constraint, I will need to install these safety valves to one vent pipe through a Y connection. The consulting engineer declined to do the design, saying it would violate the code, what do you guys say?

To try to answer your question the way you asked it would take a fairly extensive code review. You have to help us by giving more details. What kind of boiler is this? What is its capaicty? What exactly do you propose to do in your design? What is their argument?
