Specifies the thrust load acting back on the relief valve piping if there is an umbrella fitting between the vent stack and the relief valve piping.

If the vent stack is hard piped to the relief valve piping, then this intermediate thrust is balanced by tensile loads in the pipe and can be ignored.

Thrust load acts directly on valve opening.

Only the valve pipe/vent stack interface thrust acts in this configuration.
