13.1 Checking for contamination
In order to be able to check the boiler for contamination in the following years it is

into operation. This value can be different with each type of boiler.
In order to be able to measure this value follow the next procedure:
- Press the MODE-key for 5 seconds.
- The display will show COdE followed by an arbitrary number;
- Select by means of the + or the - key the code C123;
- Press the Store-key to conrm the code (code blinks 1 x);
- Press the MODE-key until SERV is shown;
- Press the STEP-key until 2 is shown;
alternately 2 and OFF will be shown.
- Undo the top test nipple on the gas valve (g. 13.1.a);
- Connect the hose of the digital pressure gauge to the top test nipple of the gas valve
- Press the + key until the maximum value is achieved;
The fan will function to its maximum revolutions (burner stays off)
- Measure the under pressure and write down this value.
At the next service visit this value may drop by 20% of its original value recorded on
commissioning. If this value has dropped by more than 20% the boiler requires full
maintanance.
- Press the - key until OFF is shown (keep key pressed)
With this the procedure is nished.
