We interpret this provision to defer to the equipment manufacturer's installation instructions. Steam traps used to drain condensate from steam mains, are shown in Figure 10.3.14. The vent is also where the air in the steam system leaves. Air Admittance Valves (aka Studor vents) are “negative-pressure-activated” one-way mechanical valves. Sometimes we can’t (or don’t want to) vent through the roof line.In these rare cases plumbers use an Air Admittance Valve. Clean the drain lines at the access point.
