Note on condensate drain
■
Condensate will form in the flue system. The return
of this condensate must be prevented on site. Take
appropriate measures, e.g. install a condensate trap.
■
Seal the condensate drain connectors (KOA) if they
are not used. They are designed for draining any
condensate collected during the start-up phase.
