3.1.3

Checking the condensate siphon

• C heck the condensate siphon. Remove any dirt residues
and refill with clean water to the mark.
3.1.4 Checking the ignition electrode
• Check the ionisation /ignition electrode for:
- D eposits (remove any white deposits with abrasive cloth);
- T he adjustment of the ignition electrode (between 3 and 4
mm);
- The quality of the gasket and condition of the porcelain
(this should not be cracked) inspect and replace if neces-
sary;
• C heck the ionisation current after 1 minute on the display
code fl, see par. 2.9.6.
If the read-out value is lower than 3 or higher than 9µA, check
cable and connections are sound if OK replace the ignition
electrode.

The ignition cap is fixed on the ignition electrode and therefore
cannot be removed.
3.1.5 Checking the combustion
• M easure the O /CO percentage and the flue gas tempera-
2 2
ture at the flue gas sample point.
Do this as follows:
- Heat the water temperature in the boiler to approx. 70°C;
- Unscrew the top of the flue gas point of measurement;
- Measure the O /CO percentage and compare this to the
2 2
check values in table 11.

Ensure that the analysing probe has a gas tight seal in the
sampling point with the probe end in the centre of the flue
duct.
