Overview
This document contains a Supplement to the scope of EN 15502-2-1:2022 and provides the requirements necessary for this Supplement. This document includes gas-fired central heating boilers of types C1 to C(11) and types B2, B3, and B5: a) fully premixed appliances equipped with an adaptive combustion control function (ACCF) that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance including gas grids for natural gases of the second family where up to 20% hydrogen volume is added to the natural gas (H2NG-Y20); b) the appliances are fully premixed, equipped with a Pneumatic Gas Air Ratio controller (PGAR) that are intended to be connected to gas grids for natural gases of the second family where up to 20% hydrogen volume is added to the natural gas (H2NG-Y20), where the quality of the distributed gas without adding the hydrogen is not likely to vary to a large extent over the lifetime of the appliance. The only technical change compared to EN 15502-2-1:2022 is the addition of the scope of application compared to EN 15502-2-1:2022. EN 15502 consists of the following parts under the general title Gas-fired heating boilers: - Part 1: General requirements and tests; - Part 2-1: Specific standard for type C appliances and type B2, B3 and B5 appliances of a nominal heat input not exceeding 1 000 kW; - Part 2-2: Specific standard for type B1 appliances; - Part 3-1: H2NG and ACCF - Expansion of EN 15502-2-1:2022. The responsible committee for this standard is NA 032-03-01-03 AK "Zentralheizungskessel für gasförmige Brennstoffe" ("Central heating boilers using gaseous fuels") at DIN.
