Combustion figures
| Figure | Natural gas (G20) |
|---|---|
CO₂ at high rate More infoHide infoG20 natural gas, after 5 minutes in full load mode (check programme P.01), measured at the flue gas analysis point. Case on means front casing closed; case off means front casing removed. The CO₂ is set with the front casing removed (MI 7.15). Set for Wobbe index W₀ 15 kWh/m³. |
|
CO₂ at low rate | Not given in MI |
Maximum CO More infoHide infoThe manual gives two figures. Section 7.14 gives CO in full load mode ≤ 250 ppm. The combustion chart (Appendix J) checks for CO less than 350 ppm at maximum and minimum rate, and its recheck box after checking seals says less than 335 ppm. |
|
CO/CO₂ ratio More infoHide infoThe manual gives two figures: section 7.14 gives ≤ 0.0031; the combustion chart (Appendix J) gives less than 0.004 at maximum and minimum rate. |
|
O₂ | Not given in MI |
Working inlet pressure More infoHide infoPermissible connection pressure for Great Britain, natural gas G20, measured at the measuring nipple on the gas valve with check programme P.01 running (MI 7.13). The maintenance table says to check it at maximum heat input. Technical data gives G20 gas supply pressure 2.0 kPa. |
|
Gas rate at maximum More infoHide infoG20 gas flow at P max. in hot water and heating mode (Technical data). Gas flow at P min.: 25c 0.540, 30c 0.646, 35c 0.762 m³/h. |
|
Flue integrity More infoHide infoAt the air analysis (air inlet) test point, boiler at maximum rate (MI 7.12 and combustion chart, Appendix J). | O₂ ≥ 20.6% CO₂ < 0.2% |

Check these figures against the MI for the appliance in front of you, matched by GC number and manual date. Combustion work needs a calibrated analyser and a Gas Safe registered engineer.
