9 Start-up procedure
For first time start up it is necessary to set the DHW temper-
ature knob and the space heating water temperature knob
to the desired setting (see subsection 10.3.2 and 10.3.3).
Factory setting is "0".
WARNING
There is a hot water scald potential if the BC10
is set too high.
9.3

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).
Fill with water and refit the condensate trap in reverse
order.
9.4

Bleeding the gas supply valve

Loosen the screw plug on the testing nipple for the gas
connection and venting (fig. 33, pos. 1) by two turns and
fit a hose.
Slowly open the gas shut-off valve.
Run the gas that is discharged through a water bath.
Close the gas shut-off valve when no more air is
released.
Remove the hose and tighten the screw plug again.
9.5 Checking the combustion air/flue gas
connection
Check the following points:
– Is the prescribed combustion air/flue system used?
– Have the instructions for configuring the flue system as
specified in the relevant Installation instruction for the flue
gas system been observed?
