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.

Procedure
Comment
Required tool
1
Checking the gas connection pressure
The gas flow pressure relative to the
atmospheric pressure must be 1.7-
2.5 MPa (17-25 mbar) with natural
gases. The resting pressure for natural
gas must not deviate from the gas
flow pressure by more than 1.0 MPa
(10 mbar).
U-tube or digital manometer
2
Check whether the siphon has been
filled
If required, fill it via the flue spigot (at
least 1.5 l water)
3
Check the electrical connection
Power supply: Terminals L, N, PE
Control terminals: "Bus", or 7-8-9 or 3-4
4
Switch on the product, the display view
is active
Otherwise, check the fuses (4 OT)
5
Activate the chimney sweep mode
Press the
+
and
−
buttons at the same
time
6
Check the entire gas route for leaks
Leak detection spray or leak detector
(a leak detector is especially recom-
mended for checking the burner seals
for gas tightness)
If required, tighten the burner seal.
