Note
All radiators should be cold before you start
calibration. This ensures that the heat
volume can be transferred to the heating
installation.
Note
If there is an excessive air temperature at
the radiators, calibration may not be pos-
sible.

9.15.4.1 Calibrating the heat generator and
measuring the CO/CO
₂
content and gas
flow in domestic hot water mode
1.
The following steps are only required if calibration and
measurement in heating mode (
→
Page 31) could not
be completed successfully.
2.
If required, open all of the draw-off points.
3.
Set the domestic hot water temperature at the heat
generator to the maximum.
Danger!
Risk of burns and scalding!
There is a risk of scalding at the domestic hot
water draw-off points if the water temperature
is set to the maximum.
▶
Avoid contact with the water that escapes
from the domestic hot water draw-off
point.

Checking leak-tightness
▶
Check the gas pipe, the heating circuit and the hot water
circuit for leak-tightness.
▶
Check that the air/flue pipe has been installed correctly.
Condition
: Room-sealed operation
▶
Check whether the vacuum chamber has been closed
tightly.
