7 Start-up
10. Fill the installation up to a system pressure of 0.2 MPa
(2.0 bar).
Note
In a heating installation over several storeys,
a higher system pressure may be required.
11. Shut off the heating water supply.

Purging the heating installation
1.
Purge the lowest radiator until water flows out of the
purging valve without bubbles.
2.
Purge all other radiators until the heating installation is
completely filled with water.
3.
To purge the heating or cylinder charging circuit, select
check programme (→ Page 16) P.00.

runs for approx. 6.5 minutes.
4.
Press the i button again to purge the cylinder charging
circuit.
5.
Top up with water if, while the check programme is
running, the system pressure drops below 0.08 MPa
(0.8 bar).
6.
Read off the system pressure on the display at the end
of the check programme. If the system pressure has
dropped, fill and purge the installation again.
7.
Close the heating installation's filling/draining cock and
the heating water supply, and remove the hose.
8.
Check all of the connections and the entire heating in-
stallation for leak-tightness.

Filling the condensate siphon
Danger!
Risk of poisoning from escaping flue gas!
An empty or insufficiently filled condensate
siphon may allow flue gas to escape into the
room air.
▶
Fill the condensate siphon with water be-
fore starting up the product.

1.
Before filling the siphon, connect the condensate drain
pipework to the rear of the product. Refer to the inform-
ation on routing the condensate discharge pipe in the
section entitled "Connecting the condensate discharge
pipe (→ Page 12)".
Conditions: Air/flue pipe not yet connected
▶
Fill the condensate siphon via the flue gas spigot (1) (fill
quantity approx. 1.5 l).
Conditions: Air/flue pipe already connected
▶
Fill the condensate siphon via the flushing line (2) using
a funnel (fill quantity approx. 1.5 l).

Checking the gas setting
7.9.1
Checking the factory setting
Caution.
Risk of operating faults or a reduction in
the product's service life caused by the
gas group being set incorrectly.
If the product design does not match the local
gas group, malfunctions will occur or you will
have to replace product components prema-
turely.
▶
Before you start up the product, compare
the gas group information on the data
plate with the gas group available at the
installation site.
The combustion setting has been factory tested and is preset
for operation with the gas group indicated on the identifica-
tion plate. In some supply areas, these settings may need to
be adjusted at the installation site.
