This guideline applies to heating installations, distinguishing as subsections heat supply, heat distribution and heat generation. In order to ensure the overall function of an installation the ready-to-use installation must be subjected to a detailed test. The guideline provides general testing criteria in tabular form (checklists) for technical acceptance (including partial acceptance). The testing applies to all facilities serving for heat transmission (in the room and on heat exchangers), heat distribution, heat generation, building automation, fuel supply and storage, exhaust-gas handling and disposal.
