Combustion figures
| Figure | Natural gas (G20) |
|---|---|
CO₂ at high rate More infoHide infoChecked in Calibration Mode at maximum rate after running the boiler for several minutes, at the flue adaptor test point (MI 14.1). | 8.7% ± 0.2 |
CO₂ at low rate More infoHide infoChecked in Calibration Mode at minimum rate, after checking at maximum (MI 14.1). | 8.4% ± 0.2 |
Maximum CO More infoHide infoAt both maximum and minimum rate, at the flue gas test point (MI 10.2 flow chart). | < 350 ppm |
CO/CO₂ ratio More infoHide infoAt both maximum and minimum rate (MI 10.2). MI 12.1 and 14.1 also say less than 0.004. | < 0.004 |
O₂ | Not given in MI |
Working inlet pressure More infoHide infoMeasured at maximum rate in Calibration Mode; MI 10.4 says it must be at least 17 mbar. At the gas meter: 19–23 mbar. Permissible pressure drop across system pipework ≤ 1 mbar. Technical data (MI 4.1) gives inlet pressure 20 mbar (natural gas G20) without saying where it is measured. |
|
Gas rate at maximum More infoHide infoNatural gas G20, after 10 minutes (MI 4.1). Measure with other appliances and pilot lights off (MI 10.4). |
|
Flue integrity More infoHide infoAt the air inlet test point, boiler at maximum rate (MI 10.2 flow chart). | O₂ ≥ 20.6% CO₂ < 0.2% |
