Thoroughly flushing the heating installation
("hot")

1.

Operate the appliance until the boiler and the heating
system are up to temperature.

2.

Check the heating system for leaks.

3.

Connect a hose to the drain valve located at the lowest
position of the heating system.

4.

Shut off the boiler, open the drain valve and all purge
valves on the radiators and allow the water to flow out
of the heating system and the boiler quickly and fully.

5.

Close the drain valve.

6.

Fill the heating system again with water as described in
Filling the heating installation and Purging the heating
installation.

7.

Install the front casing.

9.9

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.

9.10

Checking the heating mode

1.

Activate the heating mode on the user interface.

2.

Turn all thermostatic valves on the radiators until they
are fully open.

3.

Allow the product to operate for at least 15 minutes.

4.

Purge the heating installation.

10.1

Burner anti-cycling time

To prevent frequent switching on and off of the burner and
thus prevent energy losses, an electronic restart lockout
is activated for a specific period each time the burner is
switched off. The burner anti-cycling time is only active for
the heating mode. Domestic hot water mode during a burner
anti-cycling time does not affect the time function element.

10.1.1 Setting the burner anti-cycling time

Set the burner anti-cycling time via the diagnostics code.
