Reset eGas CH (Central Heating) check programme:
Calling up the programme deletes all of the CH cor-
rection values that have been saved from previous
calibration processes. The products then starts by
fully calibrating the combustion regulation (status
S.09
).

Checking and treating the heating
water/filling and supplementary water
Caution.
Risk of material damage due to poor-qual-
ity heating water
▶
Ensure that the heating water is of suffi-
cient quality.
▶
Before filling or topping up the installation, check the
quality of the heating water.
Checking the quality of the heating water
▶
Remove a little water from the heating circuit.
▶
Check the appearance of the heating water.
▶
If you ascertain that it contains sedimentary materials,
you must desludge the installation.
▶
Use a magnetic rod to check whether it contains mag-
netite (iron oxide).
▶
If you ascertain that it contains magnetite, clean the in-
stallation and apply suitable corrosion-inhibition meas-
ures, or fit a magnetic filter.
▶
Check the pH value of the removed water at 25 °C.
▶
If the value is below 8.2 or above 10.0, clean the installa-
tion and treat the heating water.
▶
Ensure that oxygen cannot get into the heating water.
Checking the filling and supplementary water
▶
Before filling the installation, measure the hardness of the
filling and supplementary water.
Treating the filling and supplementary water
▶
Observe all applicable national regulations and technical
rules when treating the filling and supplementary water.
Provided the national regulations and technical rules do not
stipulate more stringent requirements, the following applies:
You must treat the heating water in the following cases
–
If the entire filling and supplementary water quantity dur-
ing the operating life of the system exceeds three times
the nominal volume of the heating installation, or
–
If the guideline values listed in the following table are not
met, or
–
If the pH value of the heating water is less than 8.2 or
more than 10.0.
