Cleaning the heat exchanger and condensate sump.
G Remove cleaning cover at the front bottom of the condensate sump
G Clean with plastic or stainless steel brush and water using a normal
detergent (e.g. washing up liquid). Finally rinse off with a gentle water jet.
G Re-fit cleaning cover
G Re-install burner after cleaning is completed
G Check nominal heat load and exhaust gas values
To ensure proper function of the ignition and ionization, ensure that installation
length and spacings are observed as shown in Fig. 4.
The ionization current should have the following values for burner operation:
- at min. output > 5 µA, DC (switching threshold at 0.7 µA, DC)
- at max. output > 10 µA, DC
The current ionization current can be checked as follows directly in µA:
- on boiler module (1) under parameter "C 1"
- using room control module RRG (optional extra)
