Heat cell with gas burner
7.3.1 Adjustment values
7.3.2 Establishing access to the burner
●
Remove the protective cover (see chap. 4.4.3).
●
Remove the cover and front panelling of the heat cell (see
chap. 4.8.3).
7.3.3 Checking and setting the burner
The gas burner is set at the factory to the gas type "Natural gas".
The stipulated gas inlet pressure can be seen in tab. 12-6.
The RoCon BF controller can be used to set the GCU compact to
the [Emission Measurement] function under [Full Load] and
[Base Load]. The flue gas values are checked with a flue gas
analysis device.
Auxiliary resources
– Flue gas analysis device.
– Pressure meter for measuring gas pressure.
Checking and adjustment
Adhere to the following sequence!
1. Check whether the burner is set to the correct gas type and
correct gas inlet pressure (see also chap. 4.8.4).
2. Turn the screw in the gas inlet pressure measuring
connection (fig. 4-44, item 3.3) anticlockwise by half a turn
and attach the measuring hose of the pressure meter.
3. Open the gas stopcock.
4. Measure the gas inlet pressure (idle pressure) and compare
it with the target value (see tab. 12-6). Leave the measuring
instrument connected.
If the gas inlet pressure (resting pressure) is outside the
set value range: Inform your gas supply company or
check the pressure reducer (for liquid gas).
5. Open the heating valves.
6. Switch on the ROTEX GCU compact with the main switch.
7. Start the program [Emission Measurement] on the RoCon BF
controller of the GCU compact and select the
[Full Load]
setting,
but do not confirm
.
8. Connect the flue gas analysis device to the test adapter for
the flue gas pipe.

If the burner does not start, although the power and gas
supply are properly connected and the flue gas path is
free, the cause of this fault must be found and rectified
(see chap. 7.3.4).
