Glow-worm Easicom combi (24, 28)
Combi, natural gas (LPG by conversion)
Combustion figures
| Figure | Natural gas (G20) | LPG (G31) |
|---|---|---|
CO₂ at high rate More infoHide infoSame for both sizes. Test mode P.01 set to HI, read after about 5 minutes (MI 17.3.3). Technical data (MI 5) gives these as CO₂ at Qmax DHW and gives NG case off as 9.0 ± 0.2%. LPG case off: MI 17.3.3 gives ± 0.2% but the technical data gives ± 0.3%. The gas conversion table in MI 15.1.2 has case ON and case OFF the other way round (NG case ON 9 ± 0.2 %, case OFF 9.2 ± 0.3 %; LPG case ON 10.1 ± 0.2 %, case OFF 10.3 ± 0.3 %), which contradicts MI 5 and MI 17.3.3. |

CO₂ at low rate More infoHide infoCO₂ at Qmin, same for both sizes. Given in the technical data (MI 5) only. |

Maximum CO | Not given in MI | Not given in MI |
CO/CO₂ ratio More infoHide infoBoth sizes. From the combustion check tables in MI 17.3.3. | 0.004 | 0.004 |
O₂ | Not given in MI | Not given in MI |
Working inlet pressure More infoHide infoNominal supply pressure, checked at the gas service isolation valve test point with all other gas appliances operating and the boiler forced to maximum (P.01 set to HI). The MI adds that the maximum heat input can be achieved at an inlet pressure down to 15 mbar. |
|
|
Gas rate at maximum More infoHide infoApproximate, at least 10 minutes after lighting from cold (MI 11.6.2). The technical data (MI 5) gives these NG figures as the maximum DHW gas flow rate; maximum heating gas flow rate there is 24: 1.96, 28: 2.54 m³/h (NG) and 24: 1.44, 28: 1.87 kg/h (LPG). For the 28 on LPG, the gas rate table gives 1.87 kg/h but the technical data gives 2.17 kg/h maximum DHW. |

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.
