Combustion figures

Figure	Natural gas (G20)	LPG (G31)
CO₂ at high rate More infoHide info Hot condition (Frame 52 table). The ± 0.5% tolerance is from Table 1; the Frame 52 table gives no tolerance. LPG figures are for the P models.	9.7% ± 0.5%	11.4% ± 0.5%
CO₂ at low rate More infoHide info Hot condition (Frame 52 table). Tolerance from Table 1.	8.7% ± 0.5%	10.2% ± 0.5%
Maximum CO	Not given in MI	Not given in MI
CO/CO₂ ratio More infoHide info Frames 55 and 56.	Not greater than 0.004	Not greater than 0.004
O₂	Not given in MI	Not given in MI
Working inlet pressure More infoHide info Minimum at the boiler inlet with the boiler firing (Frame 31). The inlet pressure test point is on the gas valve on the 30, 40, 60, 80 and 150, and on the inlet gas manifold on the 100 and 120 (Frame 58). Table 2 gives the gas supply as G20 20 mbar and G31 37 mbar. The fault finding charts (MI pp. 52–53) ask whether more than 18 mbar is available at the boiler, which doesn’t match the 17.5 mbar minimum.	Appliance inlet 17.5 mbar minimum	Appliance inlet 37 mbar minimum
Gas rate at maximum More infoHide info Table 1. LPG lines are the 30P, 40P, 60P and 80P. Frame 52: after 10 minutes you should read at least 90% of the nominal gas rate.	30 3.2 m³/hr 40 4.3 m³/hr 60 6.4 m³/hr 80 8.7 m³/hr 100 10.8 m³/hr 120 13.0 m³/hr 150 16.2 m³/hr	30 1.26 m³/hr 40 1.69 m³/hr 60 2.53 m³/hr 80 3.41 m³/hr 100, 120, 150 No LPG model in MI
