Danger!
Risk of poisoning and burns caused by
escaping hot flue gas!
Hot flue gas can escape and cause poison-
ing and burns if the boiler is operated with
an incompletely mounted or open air/flue
gas duct or if the boiler is operated with
internal leaks with the front casing open.
> Operate the boiler
- for commissioning
- for testing purposes
- in continuous operation
only when the front casing is fitted and
closed and the air/flue gas duct is com-
pletely mounted.
> Exclusively for test purposes such as gas
working pressure testing the boiler may
be operated with the front casing
removed for short durations ONLY but
must have a completely mounted air/flue
gas duct.

The automatic air vent cap must be loosened
before filling the heating circuit or recharging
circuit and during operation.
Purge the heating circuit and the recharging cir-
cuit using the purging program P.00
(¬section10.4).

10.1 Switching on the boiler
> Press the on/off button (¬Operating instructions).
The basic display appears on the display.
10.2 Installation assistant
The installation assistant is launched when switching on the
boiler for the first time. It provides easy access to the most
important test programs and configuration settings for
installing the boiler. The installation assistant is displayed
whenever the boiler is switched on until it has been suc-
cessfully completed.
You must confirm the start of the installation assistant.
Once confirmed, all of the heating and hot water demands
from the boiler are blocked. This status remains until the
installation assistant is completed or cancelled.
If you do not confirm the start of the installation assistant,
it will be closed 10 seconds after being switched on and the
basic display will appear. The next time the boiler is
switched on using the on/off button, the installation assist-
ant will be started again.
