DIN | 2007-05 | 63 |
This European Standard specifies the requirements and test methods for the construction, the safety and the rational energy usage for gas-fired standard and low temperature central heating boilers equipped with a forced draught burner. These boilers comprise a boiler body and a forced draught gas burner brought together at the producer's assembly facility, the whole being designed and marketed as a complete boiler. This standard does not apply to the case of the assembly of a boiler body and a forced draught gas burner designed and marketed separately. In this case, EN 303-3 applies. This European Standard applies to type B 23 boilers with a nominal heat output not exceeding 1000 kW with a water temperature at normal operation not exceeding 105 °C and with a maximum water-side operating pressure not exceeding 8 bar. This European Standard does not contain all the necessary requirements for: – condensing boilers and combination boilers; – boilers intended to be installed in the open; – boilers permanently fitted with more than one flue outlet; – boilers intended to be connected to a common flue having mechanical extraction; – boilers equipped with several combustion chambers. This European Standard does not apply to living-space dedicated boilers. This European Standard only covers type testing.
