10.3.2 Check electrodes
Ionisation electrode (1)
Danger of electric shock
Danger to life due to high voltage.
Do not touch plug contacts during the ignition process.
Caution
The wire of the ionization electrode must not be bent since it can
break easily.
The ionization electrode must always be in contact with the flame.
The distance from the ionization electrode to the blast tube must be
maintained in accordance with Fig. When replacing the ionization
electrode, check its distance to the burner and correct if required. To do
this, loosen the burner on the mixing tube and move it until the distance
corresponds to the required dimension.
For measurement of the ionisation current, pull plug from the gas-firing
automaton and connect ammeter between plug and electrode.
Ignition electrodes (2)
To ensure that the Paramount unit ignites reliably and quietly, the
installation position and the spacing between the ignition electrodes shown
in the illustration must be complied with.
10.4 Specific maintenance operations
10.4.1 Replacing air vent
Caution
Only genuine spare parts may be used.
Caution
Drain off boiler water.
The boiler water has to be drained before the air vent is removed,
otherwise water will leak out.
A defective air vent may only be replaced by a genuine spare part; this
guarantees optimum venting.
10.4.2 Removing and installing the gas burner
Caution
Close the gas valve before carrying out any work.
Remove the gas burner before cleaning the heating surfaces.
