System boiler, natural gas
Combustion figures
| Figure | Natural gas (G20) |
|---|---|
CO₂ at high rate More infoHide infoIn chimney sweep mode at maximum heating input, after running the boiler for several minutes, with the case front panel fitted. | 8.7% ± 0.2 |
CO₂ at low rate More infoHide infoIn chimney sweep mode at minimum input. If CO₂ is reset at one rate, recheck the other. | 8.4% ± 0.2 |
Maximum CO More infoHide infoFrom the commissioning flow chart. CO and ratio are measured at maximum DHW input and minimum input. |
|
CO/CO₂ ratio | <0.004 |
O₂ | Not given in MI |
Working inlet pressure More infoHide infoAt the gas meter: 19–23 mbar (Fig. 41a). Boiler at maximum rate. The text in 7.5.1 and the fault finding chart say at least 17 mbar at the gas cock test point, while Fig. 41a shows 18–22 mbar at the gas cock. Dynamic (nominal) inlet pressure in the technical data: 20 mbar. |
|
Gas rate at maximum More infoHide infoNatural gas G20, after 10 minutes, with all other appliances and pilot lights off. |
|
Flue integrity More infoHide infoAt the air inlet test point, boiler at maximum rate. | O₂ ≥ 20.6% CO₂ < 0.2% |
