On a Section I boiler, the manufacturer provided a 3" FNPT connection for the SRV, but the SRV that was provided has a 2" MNPT connection.
Question #1: It is my interpret PG-71.3 that the connection between the boiler and the SRV must be the same size as the SRV inlet (2"), not necessarily the boiler connection, meaning it can be reduced. Is this correct?
Question #2: Am I permitted to install a threaded flange set on the inlet of the valve to make removal of the valve easier? PG-71.2 prohibits any "unnecessary" pipe or fittings in the area. Is a flange considered unnecessary?
