The oven must discharge through an indirect waste pipe by means of an air gap. The drain fitting is
supplied with a 1-1/2-inch (41mm) NPT thread.
A union is required. Install a 1-1/2-inch (41mm)
diameter connection, drain line and clamp into
place. The drain line must always be a positive
gradient away from the Combitherm oven and not
more than 12-inches (305mm) before an air gap.
