Provide a trap for the condensate drain and route the condensate into the
sewerage system.
Protect the condensate drain from frost.
Fill the trap with water.
The effective height of the trap h (mm) must exceed the maximum underpressure
or overpressure at the condensate connector (1mm WC = 10Pa).
h = 1.5 x p (mmWC) + 50 mm (min.)

The trap drain line must not be connected directly to the public sewage system,
but rather must be able to run out freely. Vent longer drain lines to prevent
condensate backing up in the line (provide additional vent in trap drain line).
