11E. 04.99• G.13.11.02Start-upRGL60Adjusting gas burner and boilerThe burner can be put into operation once the installation and assembly work has been completed.• Measure inlet pressure with U-pipe pressure gauge at measuring point "A".max. 360 mbar (KE 15), max. 70 mbar (KE 10, static pressure)min. 18 mbar (flow pressure) on RGN...-Nmin. 35 mbar (flow pressure) on RGL...-F• Burner and gas assembly are preset at factory to low output. This enables a soft burner start-up.• Adjusting the burner to the desired nominal output in accordance with the adjustment tables onPages 10, 11.To do so:• Check gas working pressure with U-pipe pressure gauge at measuring point "B" outlet pressure.Caution !Minimum pressure difference (inlet-outlet pressure) 5 mbar!• Adjust gas pressure and air flow measurement "A" according to adjustment tables, PP. 10, 11.• Check exhaust gas values here without fail (CO, CO 2 or O 2 ).• Depending on the system, the setting values must be corrected.• After completion of adjustment, check the setting data.• Check the gas pressure monitor after start-up. To do so, close ball valve slowly; burner must shutdown but not go into fault mode.Burner output Boiler outputat η = 92%Gas type Natural gas E: Hin = 10.4 [kWh/m3] Air flowmeasurement "A"[kW] [kW]Gas nozzle pressure[mbar]Gas flow[m3 /h] [mm]25.0 23 LL 2.1 2.9 10 - 1133.7 31 LL 3.8 3.9 11 - 1239.1 36 LL 5.5 4.5 12 - 1344.6 41 LL 6.8 5.1 13 - 1550.0 46 LL 8.7 5.7 15 - 1858.7 54 LL 11.7 6.7 20 - 26Burner output Boiler outputbei η = 92% LPG 3B/P: Hi,n = 25,8 [kWh/m3] Air flowmeasurement "A"[kW] [kW]Gas nozzle pressure[mbar]Gas flow[m3 /h] [mm]25 23 2.8 1.0 10 - 1133.7 31 5.3 1.4 11 -1239.1 36 7.2 1.6 12 - 1344.6 41 9.0 1.8 13 - 1550.0 46 11.0 2.1 15 - 1858.7 54 14.0 2.4 20 - 26Exhaust gas values Natural gas LL+E LPG propane 3B/PO 2 content 3.5-5.0%CO 2 content 9-10% 11-12%
