10 Commissioning
At the time of commissioning, complete all relevant sections
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.
a
Danger!
Risk of poisoning and burns caused by
escaping hot flue gas!
Hot flue gas can escape and cause poisoning
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 completely
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.
i The
automatic air vent cap must be released
before filling the heating circuit or recharging
circuit and during operation.
Purge the heating circuit or the recharging circuit
using the purge program P.00 (¬ section
10.2).
Auxiliary service equipment:
The following test and measuring equipment is required for
commissioning:
– CO2 measuring instrument
– Digital or U-tube manometer

circuit purging
1 x left selection button ("Cancel"): Exit purging program
The internal pump is cyclically actuated.
Note: The purge program runs 7.5 min per circuit.
P.01 Maximum load test program:
The boiler is operated at maximum heat input after successful
ignition.
P.02 Minimum load test program:
The boiler is operated at minimum heat input after successful
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 circuit".
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".
i If
you do not press a button for more than
15 minutes. the test programs are stopped automatically.
The boiler switches to normal operating
mode.
To terminate the test programs, you can press the left-hand
selection button " " ("Back", "Cancel") at any time.
