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 fitted.
>
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 released
before filling the heating circuit or recharging
circuit and during operation.

The purge program runs 7.5 min per circuit.
P.01
Maximum load test program:
The boiler is operated at maximum heat input after suc-
cessful ignition.
P.02
Minimum load test program:
The boiler is operated at minimum heat input after suc-
cessful ignition.
P.06
Filling mode test program:
The diverter valve (VUV) is moved to the mid-position.
The burner and pump are switched off (to fill or drain
the boiler).
10.1 Overview of the test programs
1)
Purging the heating circuit:
Diverter valve in heating position, actuation of internal pump
for 9 cycles: 30 sec. on, 20 sec. off. Display: "Active heating cir-
cuit".
Purging the hot water circuit:
After the above-mentioned cycles have run or the right-hand
selection button has been pressed again: Diverter valve in the
hot water position, actuation of the internal pump as above.
Display: "Active hot water circuit".

If you do not press a button for more than
15 minutes. the test programs are stopped auto-
matically. The boiler switches to normal operat-
