Comment
The gas flow pressure relative to the
atmospheric pressure must be 1.8-
2.5 kPa (18-25 mbar) with G20 nat-
ural gases. For natural gas, the gas
connection pressure (resting pres-
sure) must not deviate from the gas
flow pressure by more than 0.5 kPa
(5 mbar).
If required, fill it via the flue spigot (at
least 1.5 l water)
Power supply: Terminals L, N, PE
Control terminals: "Bus", or 7-8-9 or 3-4
Otherwise, check the fuses (4 OT)
Press the + and − buttons at the same
time
