05. MAINTENANCE 5.5 Setting the ignition electrodes Setting the ignition electrodes Proper setting of the electrodes is essential to ensure satisfactory opera- tion of the burner. If the spark hits the metal the efi ciency will be lower and will also cause radio disturbance. There is also a risk that carbonisation will occur.
05. MAINTENANCE 5.6 Suction plate Suction plate In the case of higher power, as well as with boilers featuring overpressure in the combustion chamber, it is possible to achieve higher fan pressure by altering the position of the suction plate, see illustration. The plate is located beneath the outer half of the fan housing, see illustration, Clea- ning the fan wheel.
