Report Nr.: B 07/07/0968 EU
Inspection results:
The examination of the gas appliances in the context of the safety-relevant approvals resulted in that a safety operation with natural gas and LPG for the listed countries is inconsideration of the requirements is ensured under fulfillment of listed restrictions. The safety and automatic control correspond to the regulations and function duly. The pollutant emission is lower than the permissible limiting values.
This test report is written for the certification by DVGW (German association for gas and water e.V., Josef –Wirmer –Strasse 1 –3, D–53123 Bonn) as confirmation of the conformity. Publication and passing on to third are permissible only in complete, unabridged form. Publication or spreading of excerpts, summaries, valuations or other working on and transformations, in particular for advertisement purposes, is permissible only with previous written agreement of the DBI-GTI gGmbH Freiberg. The publication of the page 1 (first page) is permitted. The inspection results represented in this report exclusively refer to the test samples. Evaluations of the results regarding the fulfilment of the essential safety requirements of the European directive 90/396/EEC in the context of this report take place informatively for the client. It represent no evaluation in the sense of the conformity procedure for the type approval certificate, which is reserved only by the certification body.
