2 Carry out a general inspection of the boiler for dirt and dust and clean as necessary. x x
3
Visually inspect the complete heat engine for its general condition and for signs of
corrosion, sooting or other forms of damage. If damage is evident proceed to column
2.
xx
4
Measure the gas flow rate during operation with maximum load. If the gas flow rate
complies to the Table 5.2 continue with column 1, if not proceed to column 2.
xx
5
Check the gas inlet working pressure operation with maximum load. If the gas inlet
working pressure complies to the Table 5.1 continue with column 1, if not proceed to
column 2.
xx
6
Check combustion by measuring CO, CO
2
and CO/CO
2
. If the values are outside the
tole rances of Table 9.1 proceed to maintenance column 2. You must not proceed with
the maintenance if a new burner door seal kit is not available
(Article No. 0020038679).

9 Remove the compact thermal module. x
10
Check the integrity of all combustion circuit seals, especially the burner door seal. If
there are any damages repair them before proceeding.

11 Clean the heat exchanger. x
12 Check whether the burner is dirty and clean it if necessary. x
13 Check the condensate siphon in the boiler, clean and fill if necessary. x x
14 Check the condensate ducts in the boiler and clean if necessary.

19
Check the boiler for leaks of any kind (gas, flue gas, water, condensate) and rectify as
necessary.

If you had problems with the CO, CO
2
, CO/CO
2
-values in Step 6 before the mainte-
nance, check them again now (see Table 9.1). If they are outside of the tolerances of
Table 9.1 make an adjustment, see section 9.1.
