Maintenance
7.1
Checking the water connections for leakage
Tighten screw connections on the water side while the
boiler is still at operating temperature.
Refilling
Water must be refilled, if the water pressure falls below
the set flow pressure. Then allow the heating water to
cool, bleed the filling hose and refill via the filling and drai-
ning cock.
7.2
Maintenance includes
- Cleaning the flue gas heat exchanger and condensate
collector
- Checking the burner
- Checking the ignition electrode, distance from burner
approx. 4-5 mm, set position correctly where necessary
or replace
-
CO

(O2) measuring (according to section 5.3)
7.3
Cleaning the heat exchanger
- Disconnect the boiler from the electrical supply (pull out
the plug)
- Close the gas appliance cock
- Remove the front boiler panel (open the control flap lid,
push the front cover upwards and pull out)
- Disconnect the electrical connections to the gas sole-
noid valve
- Pull off the fan connector plug
- Remove mounting opening cover
- Unscrew the threaded of the supply pipeline to the gas
solenoid valve (fig. 15)
- Remove fan
- Detach the screw mounted burner plate (fig. 15)
- Remove the burner plate and bat-wing burners (fig. 16
und fig. 18)
- Wet clean the heat exchanger (do not use steel wire
brushes) (fig. 17)
The inspection opening must be closed during
wet cleaning
- Clean the condensate drain
After cleaning, assemble in reverse order. The entire gas
way / gas route tightness check up (with leak detection
spray) is necessary after the assembly.
7.4
Function check
- Set the gas boiler according to 5.3
- Check all gas boiler connections for leaks
- Check the system pressure, replenish where necessary
(at least 1.5 bar)
-
Bleed the gas boiler
- Complete the test record sheet

Emission measurement
To access the service operation menu, press ‘MODE’ and ‘+’.
Service operation, which is carried out in heating mode,
can be recognised by the fact that the current level alter-
nates with the characters ‘SEr’ in the display.
When this operation mode is accessed, the burner starts
up at 50% capacity. The output can then be varied bet-
ween 0 and 100% using the ‘+’ and ‘-’ keys.
To exit this operation mode, press the ‘RESET’ key (or the
mode is automatically exited after 20 minutes).
