Installing a Baxi EcoBlue combi or system boiler No 10 Combustion check
Here we show you how to perform a boiler combustion check. Connect the flue gas analyser and then set the boiler to maximum rate. The gas inlet test pressure point can be easily found on the gas service cock underneath the boiler. The working pressure at the boiler inlet should be at least 17 millibars. Set the boiler to maximum rate and allow the combustion to stabilise. Carry out the Flue Integrity Combustion Check by inserting the analyser probe into the air inlet testing point, allowing the reading to stabilise. A positive check will show a reading of oxygen equal to or greater than 20.6 per cent and carbon dioxide at less than 0.2 per cent. Next, check the Carbon Monoxide and Combustion Ratio while the boiler is still running at maximum rate. Insert the analyser probe into the flue gas test point. Once stabilised, a positive check will show a reading of 8.7 per cent plus or -0.2 per cent. Now set the boiler to the minimum rate and allow the combustion to stabilise. Insert the analyser probe into the flue gas test point, allowing the reading to stabilise. A positive check will show a reading of 8.4, plus or minus 0.2 per cent. That completes the test. Cap off all test points. Complete the Benchmark checklist, recording the Carbon Monoxide and combustion ratings.
