Ɣ
Remove the upper burner trim (see chapter 4.9.3).
7.3.3 Checking and setting the burner
The gas burner is factory-set to the gas type "Natural gas". The
stipulated gas inlet pressure can be found in tab. 12-5.
The RoCon BF control cab be used to set up the GCU compact
to the function [Emission Measurement] under [Full Load] and
[Base Load]. The flue gas values are inspected with a flue gas
analysis device.
Auxiliary resources
–
Flue gas analysis device.
–
Pressure meter for measuring gas pressure.
Checking and setting
Observe the sequence!
1. Check whether the burner is pre-set to the correct gas type
and the correct gas inlet pressure (see also section 4.9.4).
2. Turn the screw in the gas inlet pressure measuring
connection (fig. 4-32, item 3.3) anticlockwise by half a turn
and push up the measuring hose of the pressure meter.
3. Open the gas stopcock.
4. Measure the gas inlet pressure (idle pressure) and compare
it to the target value (see tab. 12-5). Leave the measuring
instrument connected.
Î
If the gas inlet pressure (resting pressure) is outside the
set value range: Inform your gas supply company or
check the pressure regulator (for liquid gas).
5. Open the heating valves.
6. Switch on ROTEX GCU compact with main switch.
7. Start the [Emission Measurement] on the RoCon BF Control
of the GCU compact and select the setting

If the burner does not start, even with the power and
gas supply properly connected and with the flue gas
path free, the cause for this fault must be found and rec-
