This is done by measuring, checking andobserving.Maintenance is required in order to eliminate any devia-tions of the actual condition from the specified condi-tion.This normally is done by cleaning, adjustment and, ifnecessary, replacing individual components that are sub-ject to wear.You must carry out an annual inspection of theVaillant ecoTEC.It is possible to perform a quick, accurate inspectionwithout removing components by requesting data fromthe DIA system, carrying out the simple visual checksindicated in Table 8.2 and performing a flue gas meas-urement.The maintenance intervals (at least once every 5 years)and their scope are determined by the heating engineerbased on the condition of the boiler found during theinspection.All inspection and maintenance work should be per-formed in the order specified in Table 8.2.
