### 10 Test results The evaluation and comparision of the measurement data of the manufacturer shows that the results given in clause 9 on the test of the boiler performance requirements as documented in report no. H-C2 1190-01/08 are not negatively influenced by the changes on the burner pot. There are expected no negative influences on the boiler performance due to the changes on the housing of the heating boilers. The changes on the burner pot and on the housing are described in test report no. H-A 1190-04/12.
