Required tool
1
Starting up the product
2
Checking that the flue gas sensor
works correctly
See section "Checking that the flue gas
sensor works correctly".
Vaillant flue gas restrictor
3
Check the entire gas route for tightness
Use leak detection spray or a leak
detector.
Leak detection spray/leak detector
4
Check the entire water route for tight-
ness
Carry out a visual check.
5
Measuring the chimney draught
The maximum draught must not ex-
ceed 15 Pa. If the draught is too great,
the chimney draught must be restricted
using suitable measures.
Analyser for chimney draught
6
Checking combustion
Check for flue gas exit.
Target value for nominal heat input:
Only carry out the measurement after
ten minutes of normal operation.
–
Natural gas: CO 200 ppm
Liquefied petroleum gas: CO
300 ppm
Dew point hygrometer
CO analyser

Checking the gas flow pressure
See section "Checking the gas flow
pressure".
U-tube or digital manometer

Troubleshooting
Symptom
Possible cause
Measure
The product cannot be started
up. The ignition flame does not
ignite.
The gas supply is interrupted.
1.
Secure the gas supply.
2.
For liquefied petroleum gas: Replace an empty gas cylinder
with a full one.
3.
Ensure that the isolation valve on the gas connection is
open.
There is air in the gas supply
line.
▶
Open and close the water tap several times in order to remove
air from the gas supply.
The Piezo igniter is defective.
▶
Replace the entire thermocouple.
The safety cut-out or flue gas
sensor is defective.
1.
Check the safety cut-out and flue gas sensor.
2.
Replace the defective component.
The ignition flame goes out
after the rotary power switch
is released.
The safety cut-out has been
triggered or is defective.
▶
Replace the entire thermocouple.
The flue gas sensor is defect-
ive.
▶
Replace the entire thermocouple.
The thermoelectric voltage is
insufficient.
▶
Replace the entire thermocouple.
The ignition flame is burning but
the product does not start up.
The cold-water isolation valve is
closed.
▶
Ensure that the cold-water isolation valve is open.
The strainer in the cold water
inlet is dirty.
▶
If required, clean the strainer in the cold water inlet.
The product switches off during
operation.
Incorrect installation of the flue
gas guiding (flue pipe is too
short).
▶
Check that the flue system has been installed correctly and
that there are no problems with the flue system.
The flue gas guiding is restric-
ted, which causes overheating
(flue pipe is blocked).
▶
Check that the flue system has been installed correctly and
that there are no problems with the flue system.
