7.5 Purging the gas line
▶ Undo the threaded plug on the test nipple for gas supply pressure
and venting by two turns and affix the hose.
▶ Slowly open the gas tap.
▶ Flare off escaping gas via a hydraulic seal. Remove the hose when no
more air is expelled, and tighten the plug.
▶ Close gas isolation valve.

7.6 Checking the ventilation and extract air apertures
and the flue connection
▶ Check whether the apertures for ventilation and extract air comply
with locally applicable regulations or those of your gas supplier. Have
any faults removed immediately.
▶ Check whether the flue connection complies with the applicable
requirements (

chapter 6.1, page 16).
▶ Have any faults removed immediately.
7.7 Making the heating system operational
▶ Open the fuel supply at the main shut-off valve and upstream of the
gas valve.
▶ Switch on the heating system emergency stop switch (if installed)
and/or the corresponding domestic fuse/circuit breaker.
7.8 Commissioning the control unit and burner
7.8.1 Switching on the boiler at the BC10
▶ Set the rotary selector for “maximum boiler temperature” and the
rotary selector for “set DHW temperature” to 0.
This ensures that the burner will not start yet (there is no heat
demand).
▶ Set the ON/OFF switch on the basic controller to position “1”.
The entire heating system is switched ON.
During commissioning, “-” briefly flashes on the display, then fault
display “4A”-“700” appears. Fault display “4A”-“700” appears, as
the burner is supplied in a fault state.
▶ Wait approx. 1 minute to enable the EMS connection to the RC35
programming unit (available separately) to be established.

▶ Press “Reset” on the BC10. The status display on the BC10
illuminates and the display shows the current boiler water
temperature in °C.
If fault message “A11” appears, you must set the date and time on the
RC35 programming unit. Only then will the current boiler water
temperature be displayed.
Before continuing with further commissioning steps, set the correct
parameters on the RC35 programming unit. The DHW heating
configuration (heating circuit pump and cylinder primary pump) must be
set correctly to ensure the heating system works properly. For this,
observe the installation and maintenance instructions of the RC35
programming unit.
7.8.2 Carrying out a flue gas test
Key is used by your heating contractor for the flue gas test.
The heating control unit operates for 30 minutes at a higher flow
temperature (ensure heat is drawn off at this time). During the flue gas
test, the decimal point illuminates in the status display.
▶ Press the key until the decimal point in the status display
illuminates (at least 2 seconds).
▶ Carry out the flue gas test.
DANGER: Risk to life through poisoning!
Insufficient ventilation can lead to dangerous flue gas
leaks.
▶ Never block ventilation and extract air apertures or
reduce their size.
▶ The boiler must not be operated, unless you
immediately remedy the fault.
▶ Inform the system user in writing of the problem and
associated danger.
When using the Logamatic 4000 control system, take
the following commissioning steps:
▶ Switch off the Logamatic 4000 control unit.
▶ Install the RC35 programming unit.
