Historically, the plumbing and HVAC industry has not nationally regulated the use of plumbing pipes and accessories used for thermoplastic flue gas venting (FGV) installations. Currently, the use of plumbing Schedule 40 solid wall or foam core drain, waste and vent (DWV) pipe and fittings are allowed if they are referenced as options in the appliance installation instructions.
