WARNING
There is a hot water scald potential if the BC10
is set too high.
8.3 Filling the condensate trap
• Make sure that you fill the condensate trap with water.
This is to prevent exhaust gases from entering the room.
• Remove the condensate trap (see fig. 32) by disconnecting
the connection to the heat exchanger and the
connection to the condensate bypass pipe.
• Fill with water and refit the condensate trap in reverse
order.
WARNING
Danger of fatal accident due to poisoning. If the
condensate trap is not filled with water, flue gas
can escape and put people's lives at risk.
