Inspection and maintenance work
The table below lists the manufacturer requirements with respect to minimum inspection and maintenance intervals. If na-
tional regulations and directives require shorter inspection and maintenance intervals, you should observe these instead of
the intervals listed. Each time inspection and maintenance work is carried out, carry out the required preparatory and com-
pletion work.
Note
Note: For products that are not part of the annual service agreement, maintenance must be carried out at least
once every five years.

Maintenance work
Interval
1
Ask the end user whether any significant problems occur when operating
the product
Annually
2
Use the diagnostics system to check the product's fault history
Annually
3
Visually inspect whether the air/flue pipe and its opening have been in-
stalled correctly in accordance with the set-up instructions
Annually
4
Check that the unit has been installed correctly and the connections have
been secured
Annually
5
Check all of the connections for tightness
Annually
6
Check that the condensate pipe is in good condition, that it is leak-tight
and that the drain is correct
Annually
7
Check whether all of the externally routed condensate pipes are dimen-
sioned correctly and have been insulated sufficiently (frost protection)
Annually
8
Check whether the gas flow rate corresponds with the specifications on
the data plate and lies within the tolerances specified in these instructions
Annually
9
If the gas flow rate lies outside of the tolerances specified in these in-
structions, eliminate the fault in accordance with the regulations and the
current technology
Annually
10
Check the general condition of the product and, if required, eliminate any
faults that are found
Annually
11
Carry out the combustion analysis: Measure the CO content, CO
₂
content
and the CO/CO
₂
ratio. For products with a rear air/flue connection: The
combustion analysis can only be carried out when the unit casing has
been removed; it is not necessary to test these products for flue gas recir-
culation
Annually
12
Check the product's recirculation at the supply air test point on the air/flue
pipe. If required, inspect the entire air/flue system and, if necessary, cor-
rect the fault
Annually
13
Disconnect the product from the electrical installation
Annually
14
Check and, if required, correct the electrical installation
Annually
15
Remove the unit casing, check the condition of all of the functional com-
ponents, in particular for leaks, corrosion, rust, etc. and, if required, repair
any damage
Annually
16
Visual inspection of the heat exchanger and burner seals
Annually
17
Carefully clean the inside of the product: The air passages to the burner
must be clear and clean
Annually
18
Close the installation's gas stopcock and, if required, service valves
Annually
19
Check the quality of the heating water: Clarity (clouding), correct inhibitor
and pH value
Annually
20
Removing the gas-air mixture unit
If required, at least every
5 years

21
Checking the burner
If required, at least every
5 years
