Glow-worm Energy 2 combi LPG (30c P)
Combi, LPG (G31 propane) only
Combustion figures
| Figure | Natural gas (G20) | LPG (G31) |
|---|---|---|
CO₂ at high rate More infoHide infoFull load: check programme P.01 set to 100, read once stable (5 minutes), at the flue gas analysis point. Adjust to the front casing off figure (MI 10.5). This manual covers the LPG model only. | Not given in MI |
|
CO₂ at low rate | Not given in MI | Not given in MI |
Maximum CO More infoHide infoAt full load, front casing off or on (MI 10.5). The Benchmark flowchart in the appendix (MI p. 44) uses CO less than 350 ppm as its check at maximum and minimum rate (one box prints 335 ppm). | Not given in MI | ≤ 250 ppm |
CO/CO₂ ratio More infoHide infoAt full load (MI 10.5). The Benchmark flowchart in the appendix (MI p. 44) uses a ratio less than 0.004 at maximum and minimum rate. | Not given in MI | ≤ 0.0031 |
O₂ at high rate More infoHide infoAt full load, same figure with the front casing off or on (MI 10.5). | Not given in MI | 5.1 ±0.8 vol. % |
O₂ at low rate | Not given in MI | Not given in MI |
Working inlet pressure More infoHide infoG31, at the test nipple on the gas stopcock, boiler at full load (P.01) with hot taps open (MI 7.10.2). Technical data gives the same G31 supply pressure. Data plate factory setting: G31 – 37 mbar. | Not given in MI |
|
Gas rate at maximum More infoHide infoThe manual contradicts itself on the unit: MI 7.10.1 gives 2.38 kg/h for Qnw 30.6 kW (allowed +5%: 2.50, −10%: 2.14 kg/h), measured at the gas meter with the front casing fitted, P.01, after 5 minutes. The technical data (MI J) gives 2.38 m³/h for hot water at P max. MI 7.10.1 also lists Qnw 24.7 kW: 1.92 kg/h and 25.7 kW: 2.00 kg/h; the technical data gives this boiler’s hot water input as 30.6 kW. Technical data gas flow at P min: 0.598 m³/h. | Not given in MI |
|
Flue integrity More infoHide infoAt the air inlet test point, boiler at maximum rate. From the Benchmark flowchart (MI p. 44). | Not given in MI | O₂ ≥ 20.6% CO₂ < 0.2% |
