5.5.2 CHECKING THE GAS RATE
▶ The gas rate should be measured at the gas meter after the boiler has
been operating for a minimum of 10 minutes at maximum output.
▶ See Technical data section on page 6 of this manual for gas rates and
CO/CO
2
ratios.
▶ Where a gas meter is not available (e.g. L.P.G.) the CO/CO
2
must be
checked.
5.5.3 GAS RATING TEST
▶ Ensure all other gas appliances are isolated.
1.Set the boiler to maximum output by pressing and the
buttons together for at least 5 seconds.
The chimney sweep symbol (1) will be displayed at the top of the
