6.4 Installing the condensate drain

Notes on condensate drainage.
• The condensate that forms in the boiler
and possible in the flue pipe must be prop-
erly drained away from the boiler.
• The condensate which forms in the flue
pipe can be drained via the boiler (install
flue pipe with downward slope towards
the boiler).
• Make sure that drainage of the conden-
sate into the public sewer system con-
forms with the applicable national
regulations.
• Also observe any applicable local regula-
tions.
