Combustion figures
| Figure | Natural gas (G20) |
|---|---|
CO₂ at high rate More infoHide infoCheck programme P.01 set to 100 (100% = Pmax). Wait 5 minutes for a stable reading, then measure at the flue gas analysis point. The MI table heading says the figure applies with the front casing removed or installed. | 9.2 ±1% |
CO₂ at low rate | Not given in MI |
Maximum CO | Not given in MI |
CO/CO₂ ratio | Not given in MI |
O₂ | Not given in MI |
Working inlet pressure More infoHide infoMeasured at the test nipple on the gas stopcock, with the boiler at full load in check programme P.01 and one or more hot taps fully open. Technical data gives a G20 gas supply pressure of 2.0 kPa (20.0 mbar). |
|
Gas rate at maximum More infoHide infoMeasured at the gas meter with the front casing on, check programme P.01, after at least 5 minutes, all other gas appliances off. The MI table lists nominal, +5% and −10% figures by Qnw from the data plate; the lines here are the Qnw rows matching each model’s maximum DHW heat input in the technical data (25.7, 30.6 and 35.7 kW). Technical data also gives gas flow at Pmax: DHW 2.7, 3.2 and 3.8 m³/h; heating 1.9, 2.7 and 2.7 m³/h (25c, 30c, 35c). |
