| Title | Heating boilers - Part 2-7: Specific standard for gas-fired central heating units |
| Work Item Number | 00109065 |
| Abstract/Scope | This document specifies the common requirements and test methods concerning, in particular the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired standard, low temperature and condensing central heating units equipped with a forced draught burner, or dual-fuel forced draught burner when operating on gas. These units 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 appliance. The assembly on site comprising a boiler body complying with EN 303-1:2017 and a forced draught gas burner complying with EN 676:2020 and designed and marketed separately are covered by EN 303-3:1999+A2:2004. This document applies to types B23 and B23P boilers with a water temperature at normal operation not exceeding 105 °C and with a maximum water-side operating pressure not exceeding 10 bar. An alternative method to the test method applied to determine the useful efficiency is added for the units fitted with condenser (Annex B (informative)). This document does not cover boilers under the scope of the Pressure Equipment Directive (PED) which are covered by EN 14394:2005+A1:2008. |

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
In the case of undated standard, a link to the last dated version is provided.
In the case of series, a link to each standard identified in the series is provided.
We also invite you to check (via the website) whether corrigenda and/or amendments shall be read in conjunction with the main standard.
