Checking the safety valve function
Checking the electrical connections for firm seating
Checking all gas equipment for tightness at operating pressure
Danger
Escaping gas leads to a risk of explosion.
Check gas equipment (including inside the appli-
ance) for leaks.
Fitting the front panel
See page 30.
Checking the combustion quality
The electronic combustion controller automatically
ensures optimum combustion quality. During commis-
sioning/maintenance, only the combustion values need
to be checked. To do this, test the CO content and CO
or O
content, and record these in the report on

page 117.
Permissible CO content
The CO content must be < 1000 ppm for all gas types.

Note
Only use suitable and approved leak detection agents
(EN 14291) and devices for the tightness test. Leak
detection agents with unsuitable constituents (e.g.
nitrides, sulphides) can cause material damage.
Remove residues of the leak detection agent after test-
ing.
Note
To prevent operating faults and damage, operate the
appliance with uncontaminated combustion air.
