The vent stack should have a manual drain valve at the bottom of the stack which is spring loaded (normally closed). 1.5 m from the bottom of the vent stack should be a 3" ANSI flange connection and a 1 1/2" ANSI flange connection. Both these flanges must be Class 300. The vent should come with 3 interchangeable termination designs which are on 3" ANSI Class 300 flanges to attach to the top of the vent stack. Suitable gaskets and torque values/calculations for all flanges should be provided. See In-tend for full requirements
