During operation, acidic condensate forms in the boiler
and flue pipe. With gas combustion, the pH values are
between 3 and 4. Drain off condensate in accordance
with regulations.
Condensate from systems > 200 kW must be neutral-
ised. Condensate is treated by a neutralising agent in
the neutralising system once it is discharged from the
system.
The neutralising agent raises the pH value to between
6.5 and approx. 9.
