Condens 7000 F – 6720871560 (2019/11)
NOTICE:
When operating with LPG, observe the setting instructions enclosed
with the “LPG” conversion set!
Check the CO

value again and enter in the commissioning report
( Chapter 17.6, page 63).
7.12 Concluding the flue gas test
To conclude and change to the operating mode, observe the
corresponding technical documentation for the control unit.
7.13 Set the standard display at the control unit
To set the standard display, observe the technical documentation of
the control unit.
7.14 Recording measurements
Carry out the following measurements at the test point in the
connector (Fig. 30 and 31) and enter in the commissioning
report ( Chapter 17.6, page 63):
– Flue resistance

7.14.1 Flue resistance
The required flue resistance for the installed flue gas/air supply system
must not exceed 150 Pa (1.5 mbar).
DANGER:
Danger to life through toxic flue gases escaping.
Only operate the boiler with a chimney or flue system
( Table 17.1, page 56).
7.14.2 CO value
CO values in an air-free state must be below 100 ppm or 0.01 % vol.
Values above 100 ppm indicate an incorrect device setup, burner and/or
heat exchanger contamination, burner faults or incorrect burner setting.
Identify and eliminate the cause.
7.15 Function tests
NOTICE:
Material damage and malfunctions due to contamination!
The function of the burner may be impaired due to greater accumulation
of dust during the construction phase.
Clean the burner once the construction phase is complete
(chapter 11.7 and 11.8) or use the “air filter” accessory set.
During commissioning and the annual inspection, make sure all
regulating, control and safety equipment is functioning correctly and,
where applicable, check for correct settings.
7.15.1 Checking the ionisation current (flame current)
To test the ionisation current, observe the corresponding technical
documentation for the control unit.
