4. Dismantle the siphon and flush it through with clean water.
5. Installation of the siphon is done in reverse order.
Note
At the same time, the exhaust gas collecting tray should be
checked for soiling and should be cleaned (rinsed) if necessary.
10.3.2 Check electrodes
Ionization 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 main
tained 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.
Danger of electric shock
Risk of electric shock! Danger to life due to high voltage.
Caution! Do not touch plug contacts during the ignition process.
For measurement of the ionization current, pull plug from the gas
burner control and connect an ampere-meter between plug and
electrode.
Ignition electrodes (2)
To ensure that the Paramount four unit ignites reliably and quietly, the in
stallation position and the spacing between the ignition electrodes shown
in the illustration must be complied with.
10.4 Specific maintenance instructions
10.4.1 Replacing air vent
Caution
Only use original spare parts.
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 the gas burner
Caution
Close the gas valve before carrying out any work.
Remove the gas burner before cleaning the heating surfaces.
