Appendix
A 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
For those appliances which are not part of an annual service agreement/policy, maintenance must be carried out
at least every 5 years.
# Maintenance work Interval
1 Record all of the analysis results in the Benchmark service record in
these instructions
Annually
2 Ask the end user whether any significant problems occur when operating
the product
Annually
3 Use the diagnostics system to check the product's fault history Annually
4 Visually inspect whether the air/flue pipe and its opening have been in-
stalled correctly in accordance with the set-up instructions
Annually
5 Check that the unit has been installed correctly and the connections have
been secured
Annually
6 Check all of the connections for tightness Annually
7 Check that the condensate pipe is in good condition, that it is leak-tight
and that the drain is correct
Annually
8 Check whether all of the externally routed condensate pipes are dimen-
sioned correctly and have been insulated sufficiently (frost protection)
Annually
9 Check whether the gas flow rate corresponds with the specifications on
the data plate and lies within the tolerances specified in these instructions
Annually
10 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
11 Check the general condition of the product and, if required, eliminate any
faults that are found
Annually
12 Carry out the combustion analysis: Measure the CO content, CO₂ content
and the CO/CO₂ 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
13 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
14 Disconnect the product from the electrical installation Annually
15 Check and, if required, correct the electrical installation Annually
16 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
17 Visual inspection of the heat exchanger and burner seals Annually
18 Carefully clean the inside of the product: The air passages to the burner
must be clear and clean
Annually
19 Close the installation's gas stopcock and, if required, service valves Annually
20 Check the quality of the heating water: Clarity (clouding), correct inhibitor
and pH value
Annually
21 Removing the gas-air mixture unit at regular intervals
34
22 Checking the burner at regular intervals
35
23 Cleaning the heat exchanger at regular intervals
35
24 Check and, if required, replace the insulating mat in the burner area at regular intervals
25 Installing the gas-air mixture unit at regular intervals
