Page 3: Overview
Overview Overview General information Installation of a gas-fired heating system must be performed in accordance with the applicable regulations and guidelines. It is therefore the duty of the installer to be familiar with all applicable regulations and re- quirements. Installation, start-up and maintenance must be performed with utmost care. The burner must not be operated in rooms with high levels of air humidity (laundry rooms), dust or corrosive vapours. -

Page 8: Function
Function Function Function test of control box Danger of fatal injury from electric shocks! Disconnect electrical cable from power supply before carrying out any work on live parts! Troubleshooting may only be carried out by authorised and trained personnel! (Remote) Unlocking may only be carried out by an authorised specialist. - Page 9 Function Safety and switching functions If, at the end of the safety time, no flame forms, or there is a loss of flame during operation, a maximum of three repetitions can be carried out for each control circuit; otherwise a failure shut-down is performed. If a flame signal is given during the pre-ventilation phase, a failure shut-down will occur immediately.
- Page 10 Function Troubleshooting diagnostics After failure shutdown, the red signal lamp lights up permanently. In this state, the visual troubleshooting diagnostics can be activated according to the fault code table by actuating the unlocking key > 3 seconds. Actuate the unlocking key again for >3 seconds to activate the interface diagnostics. The interface diagnos- tics operates only when the unlocking key adapter AGK20…...

Page 14: Adjusting Gas Burner And Boiler
Start-up Adjusting gas burner and boiler Once the installation and assembly work has been completed, the burner can be put into operation. • Measure the inlet pressure with a U-tube manometer on the "pE" measuring connection. max. 360 mbar (static pressure) for MB407 min. - Page 15 Start-up Gasburner with gas ramp MB... Gas supply pressure measuring nozzle A (P Nozzle pressure measuring connection B (P N = zero point (gas nozzle pressure setting at min. output) V = Nozzle pressure to air pressure ratio in the burner tube burner tube (gas nozzle pressure setting at max.
- Page 16 Start-up Check the minimum output by checking the gas quantity on the gas meter or comparing the nozzle pres- sure with the values in the setting tables. The output can be increased by opening the air flap (increasing ST1) and decreased by closing the air flap (decreasing ST1). The excess air does not change with this set- ting.

Page 17: Adjustment Tables
Start-up Adjustment tables The values given in the tables are only guide values for commissioning. The required system set- tings must be redetermined in the event of deviating data such as boiler output, calorific value and altitude. In any case, readjustment is necessary depending on the system. A combustion check must be carried out during initial commissioning and after each adjustment. - Page 18 Start-up GG10/2-Z(-M)-N-LN GG10/2-Z(-M)-N-LN = 9,3 [kWh/m Natural gas LL: H Burner output Boiler output Stellmotor Position Gas nozzle Gas thoughput η= 92% [ ° ] [ ° ] Inlet nozzle pressure p Measure [kW] [kW] (ST0) „B“ [mbar] 2-stage 1-stage 2-stage 1-stage [mm] 2-stage 1-stage...

Page 21: Service Instructions/Dimensions
Service instructions/dimensions Service instructions/dimensions Flame control using ionisation electrode If an AC current is applied between the burner and the ionisation rod, a DC current flows due to the recti- fying effect of the flame. This ionisation current forms the flame signal and is amplified and passed to con- trol box. -
