Bibliography

This document applies to gas-fired central heating boilers, which are declared by the manufacturer to be "condensing boilers":¾of types C (excluding appliances without a fan) and B, ¾using one or more gases corresponding to the three gas families, and ¾for which the nominal heat input is greater than 70 kW but not exceeding 1 000 kW. This document only covers type testing.This document completes or modifies the standards EN 656, EN 13836, and prEN 15420 hereafter called "boiler standards". It specifies supplementary requirements for condensing boilers.
