Combustion analysis
A fume sampling point has been provided in the top part of the
anti-backflow device inside the boiler (see fig. 9).
To take the sample:
• Remove the upper panel of the boiler
• Remove the insulation covering the anti-backflow device
• Open the fume sampling point;
• Insert the probe;
• Set the boiler temperature to maximum.
• Wait 10-15 minutes for the boiler to stabilise*
• Take the measurement.
*Tests done with the boiler that is not stabilised can cause
measurement errors.

To remove the burner assembly:
• Disconnect the power and turn off the gas ahead of
the boiler.
• Undo the two screws (A fig. 10 and 11) securing the
electronic flame controller to the gas valve and remove

• Undo the screws securing the connectors (D) to the
gas valves and remove the connectors from the valves.
• Disconnect the ignition and ionisation cables (E) from
