7.17 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 (→ Page 24) and Purging
the heating installation (→ Page 24).
7. Re-fill the system until the system design pressure of
0,1 MPa (1,0 bar) is attained.
Note
The actual reading on the digital pressure
gauge should ideally be 0,05 MPa (0,5 bar)
plus an additional pressure corresponding
to the highest point of the system above the
base of the boiler – 10 m head equals an ad-
ditional 1 bar reading on the pressure gauge.
The minimum pressure should not be less
than 0,1 MPa (1 bar) in any installation. If
the system is to be treated with an inhibitor it
should be applied at this stage in accordance
with the manufacturer's instructions. Further

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. Hot water handling during a burner
anti-cycling time does not affect the time function element
(default setting: 20 mins).
8.1.1 Setting the burner anti-cycling time
Navigate to Menu → Installer level → Diagnostics

menu → D.002 Max. anti-cycl. time: Heating and con-
firm by pressing .
