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. | 8.7% ± 0.2 |
CO₂ at low rate More infoHide infoChecked in Calibration Mode at minimum rate. If CO₂ is reset at one rate, recheck it at the other. | 8.4% ± 0.2 |
Maximum CO More infoHide infoAt both maximum and minimum rate (commissioning flow chart, section 10.2). | < 350 ppm |
CO/CO₂ ratio More infoHide infoAt both maximum and minimum rate (section 10.2). Sections 12.1 and 14.1 give the same limit. | < 0.004 |
O₂ | Not given in MI |
Working inlet pressure More infoHide infoBoiler at maximum rate in Calibration Mode; section 10.3 says it must be at least 17 mbar. At the gas meter: 19–23 mbar. Technical data gives a nominal inlet pressure of 20 mbar. Permissible pressure drop across system pipework ≤ 1 mbar. |
|
Gas rate at maximum More infoHide infoTechnical data: after 10 minutes. Measure with other appliances and pilot lights off. | 4.36 m³/h |
Flue integrity More infoHide infoAt the air inlet test point, boiler at maximum rate, case front panel fitted. | O₂ ≥ 20.6% CO₂ < 0.2% |
