(Main)Gas-fired central heating boilers - Part 2-2: Specific standard for type B1 appliances
Gas-fired central heating boilers - Part 2-2: Specific standard for type B1 appliances
This European Standard specifies, the requirements and test methods concerning the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners and are hereafter referred to as 'boilers'.
Where the word boiler is used, this is to be read as the boiler including its connecting ducts, ducts and terminals, if any.
This document is to be used in conjunction with FprEN 15502-1:2021
This European Standard covers gas-fired central heating boilers type B11, B11BS, B12, B12BS, B13, B13BS:
NOTE For further background information on appliance types see EN 1749:2020
a) that have a nominal heat input (on the basis of net calorific value) not exceeding 70 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2018;
c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation;
d) where the maximum operating pressure in the water circuit does not exceed 6 bar;
e) which are declared in the technical instructions to be either a 'low temperature boiler' or a 'standard boiler'. If no declaration is given the boiler is to be considered a 'standard boiler';
f) which are intended to be installed inside a building or in a partially protected place;
g) which are intended to produce also hot water either by the instantaneous or storage principle, as a single unit.
h) which are designed for either sealed water systems or for open water systems.
For applications within the scope of the PED further requirements may be necessary (e.g. situations where the maximum allowable temperature exceeds 110 °C, or where volume times maximum allowable pressure is over 50 bar x litres).
NOTE This standard provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard, the risk associated with this alternative construction needs to be assessed.
An example of an assessment methodology, based upon risk assessment, is given in Clause 11.
This standard does not cover all the requirements for:
i) appliances 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 (see Annex AB);
j) appliances using flue dampers;
k) appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW;
l) appliances of the types A, B14, B2, B3, B4, B5 and C;
m) appliances intended to be connected to a (common) flue having mechanical extraction;
n) appliances with gas/air ratio control;
o) modular boilers;
p) boilers which can give rise to condensation under certain circumstances;
q) boilers intended to be installed in a room with a foreseeable negative pressure relative to the pressure in the flue system;
r) surface temperatures of external parts particular to children and elderly people;
s) appliances that are intended to burn natural gases of the second family where hydrogen is added to the natural gass;
t) boilers intended to be installed in areas accessible to elderly people and children.
NOTE Negative pressure relative to the pressure in the flue system can for example be caused by mechanical or thermal ventilation in airtight buildings.

European foreword
This document (prEN 15502-2-2:2022) has been prepared by Technical Committee CEN/TC 109
“Central heating boilers using gaseous fuels”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15502-2-2:2014.
The main technical changes compared to EN 15502-2-2:2014 are the following:
I) Resulting from the revision of EN 15502-1 into EN 15502-1:2021:
a) technical changes related to eco-design and energy labelling for appliances ≤ 400 kW:
1) deletion of the requirements that can be found in the legislation itself;
2) modification of the Annexes ZC and ZD;
b) new or generally reworded requirements:
1) separation between requirements and test methods in to different clauses;
2) moving additional common parts from EN 15502-2-1:2012+A1:2016 and/or EN 15502-2-
2:2014 to EN 15502-1:2021 (for example all definitions used in the parts 2 are moved to
part 1; Therefore most of the definitions in this part are now by reference to part 1);
3) Definitions added for Instructions for installation, Instructions for use and servicing, and
Technical documentation and consequently applied throughout the document;
4) Improved wording of definitions related to the air supply and combustion products circuit;
5) Improved the references of the annexes Z. The annex Z referring to the GAD has been
removed and an annex Z referring to the GAR has been inserted;
6) Only "instructions for installation" and "instructions for use and servicing" are defined.
Therefore, these are the only instructions to be used in this standard;
7) improved definitions 'ducts / circuits';
8) definition weighted value of the NOx concentration added. With regard to Ecodesign, it is
clarified that the emissions declared are the emissions when using the references gases;
c) limitation of the scope compared to the standards superseded by the EN 15502 series (that
were cited in the OJEU under the GAD):

1) Types B14 and B4 appliances, as covered in EN 297:1994 are not covered by this
standard as there seems to be a limited market for these appliances due to the introduction
of the Ecodesign Directive that only has an exemption for B11 appliances;
NOTE B14 and B4 are non-condensing appliances.
2) this document does not cover all the requirements for appliances designed and
constructed to burn gas containing toxic components. In the past it was always considered
that the gases were not toxic, however this was never clearly indicated in the scope. In fact
this is not a change of scope, but a clarification of the scope;
3) this document is not intended to cover appliances intended for connection to gas grids
where the quality of the distributed gas is likely to vary to a large extent over the lifetime
of the appliance (see Annex AB). In the past no big variation in gas quality occurred. Due to
the EASEE-gas CBP wide variations of gas quality are considered. As these were never
covered in this standard, the scope is modified to make clear that these variations are not
covered. In fact this is not a change of scope, but a clarification of the scope;
4) this document does not cover all the requirements for appliances above 1 000 kW. In fact
this is not a change of scope, but a clarification of the scope;
5) this document does not cover all the requirements for appliances having a supplementary
heater. In fact this is not a change of scope, but a clarification of the scope as these
appliances were never included in the past, however due to the Ecodesign Regulation it has
become necessary to mention this more explicitly;
II) Additional changes, not resulting from the revision of EN 15502-1 into EN 15502-1:2021
a) technical changes related to eco-design and energy labelling for appliances ≤ 400 kW:
1) no changes;
b) new or generally reworded requirements:
1) separation between requirements and test methods in to different clauses;
2) changes resulting from moving additional common parts from EN 15502-2-
1:2012+A1:2016 and/or EN 15502-2-2:2014 to EN 15502-1:2021 (for example all
definitions used in the parts 2 are moved to part 1; Therefore, most of the definitions in
this part are now by reference to part 1);
3) the definitions for Instructions for installation, Instructions for use and servicing, and
Technical documentation are now consequently applied throughout the document;
4) an annex Z referring to the GAR has been inserted;
5) only "instructions for installation" and "instructions for use and servicing" are defined.
Therefore, these are the only instructions to be used in this standard;
c) corrected mistakes:
1
As impacted by EN 297:1994/A2:1996, EN 297:1994/A2:1996/AC:2006, EN 297:1994/A3:1996, EN 297:1994/A4:2004, EN

9.2, 9.3 and the relevant subclauses of prEN 15502-2-2:2022 correct two errors present in the
EN 15502-2-2:2014 where:
9.2.1 Requirements specifies: Shall be according to EN 15502-1:2012, 9.2.1 but these efficiency
requirements are not applicable to boiler < 400 kW.
9.3 Useful efficiency at part load specifies: EN 15502-1:2012, 9.3 is not applicable but in clause
9.3 there are the following subclauses:
- 9.3.1 Requirements that are not applicable to boilers < 400 kW
- 9.3.2 Tests that are applicable to boilers having any heat input value
d) limitation of the scope compared to the standards superseded by the EN 15502 series (that
were cited in the OJEU under the GAD):
This revision only covers the update from the EN 15502-1 and an addition of an annex Z referring to the
GAR. This revision aimed not to introduce any new technical content. As some specific requirements are
not covered in the EN 15502-2-2:2014 the scope has been modified to clarify this, stating that this
standard does not include:
1) specific requirements on surface temperatures of external parts particular to children and elderly
people where relevant to ensure that this;
2) specific requirements on appliances that are intended to burn natural gases of the second family
where hydrogen is added to the natural gas;
3) specific requirements for appliances equipped with an adaptive combustion control function.
In fact these changes are not a change of scope, but a clarification of the scope;
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.
This document (Part 2-2) is to be used in conjunction with Part 1.
Relationship between this document and EN 15502-1, Gas-fired heating boilers — Part 1: General
requirements and tests:
This document is to be used in conjunction with EN 15502-1:2021 and follows the numbering structure
of EN 15502-1:2021.
Where this document states:
— shall be according to EN 15502-1:2021 (clause number) with the following modification;
— shall be according to EN 15502-1:2021 (clause number) with the following addition;
