10 Commissioning

At the time of commissioning, complete all relevant sec-

tions of the benchmark checklist found within the back

pages of this document.

Ensure that the filling and purging programs P.06 and P.00

have been allowed to run fully before the boiler is ignited

for the first time.

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).

Auxiliary service equipment:

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.

button.

> Press the right selection button to confirm the selected

language.

The language change must be confirmed a second time in

order to avoid an unintentional change.

cannot understand, you can change it again as

described below.

simultaneously and hold them down.

> Keep the right selection button and the plus button

pressed until the option for changing the language

appears on the display.
