8.3 Procedure
a) Switch of the electrical supply to the boiler
b) Close the gas valve fi rmly
In order to carry out the following work, it is necessary to fi rst remove the outer casing.
- The ignition and ionisation electrodes are installed on the front side of the boiler.
Remove the spark plug caps and inspect the same for possible damage such as signs of arcing
and contamination (replace the same if necessary).
- If the boiler is in a dusty environment, the fan impeller may get dirty. This will reduce the air
quantity delivered and may unbalance the impeller. Clean the impeller with a brush.
- Clean the condensate bottle trap. The bottle trap beaker can be easily unscrewed from the bot-
tom of the boiler. Clean the same.
- Clean the gas fi lter (if any). Unscrew the bolts of the gas fi lter cover.
Carefully remove the fi lter element. Clean the fi lter by shaking it. In the case of heavy contami-
nation, replace the fi lter. Install the fi lter and tighten the cover in place. Check for leakages.
- Check the combustion. Calibrated measuring equipment should be used to carry out gas, air
and fl ue gas measurements.
8.4 Cleaning the burner and the heat exchanger
The burner can be cleaned on both sides with a hard brush after dismantling.
The heat exchanger can be washed clean on the fl ue gas side. If the heat exchanger is heavily
contaminated, (for example soot deposition), the heat exchanger may be cleaned with a brush
and water.
The heat exchanger can be cleaned on the water side using suitable cleaning media. For advice
concerning the media that are suitable, contact the Service department of your supplier.
8.5 Cleaning the strainer of the gas combination block
The strainer in the gas control combination block can be cleaned. First dismantle the gas valve.
8.6 Ionisation measurement
For carrying out an ionisation measurement, a micro-ammeter with a measuring range of 0-200
µADC should be fi tted in the ionisation circuit. The ionisation protection can be checked in this
manner. The rated ionisation signal is from 6 to 25 µA. The minimum ionisation signal is 2.8 µA.
8.7 Service
The Stokvis Service department is always available to provide you with service and maintenance.
