7.8 Filling and purging the heating installation
1. Flush the heating installation thoroughly before filling it.
2. Observe the information on treating heating water.
3. Open all thermostatic radiator valves.
4. Loosen the cap on the automatic air vent (installed on-
site) by one or two rotations. Ensure that the opening in
the cap is not pointing in the direction of the electronic
components.
5. Connect the filling and drainage tap (to be provided
on-site) in the heating installation to a heating water
supply in accordance with the relevant standards. Do
not fill the heating installation via the product's filling
and drainage tap.
6. Open the heating water supply.
7. If necessary, check that both service valves on the
product are open.
8. Slowly open the heating installation's filling and drain-
age tap to fill the heating installation.
9. Close the purging valve as soon as water escapes.
10. Fill the installation up to a system pressure of 0.1 MPa
(1.0 bar) to 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.
12. Purge the lowest radiator until water flows out of the
purging valve without bubbles.
13. Purge all other radiators until the heating installation is
completely filled with water.
14. To purge the heating or cylinder charging circuit, select
check programme (→ Page 15) P.00.

The product does not start up and the on-site heat-
ing pump runs intermittently. The check programme
runs for approx. 6.5 minutes.
15. Press the i button again to purge the cylinder charging
circuit.
16. Top up with water if, while the check programme is
running, the system pressure drops below 0.08 MPa
(0.8 bar).
17. 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 system again.
18. Close the heating installation's filling and drainage tap
and the hot water supply, and remove the hose.
19. Check all of the connections and the entire heating
installation 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.
▶
Before starting up the product, fill the con-
densate siphon with water through the flue
gas opening in the flue gas collector.

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 opening in
the flue gas collector (2) (fill quantity approx. 1.5 l).
Conditions: Air/flue pipe already connected
▶
Remove the condensate discharge pipe (1) from the
condensate trap.
