Decorative fuel-effect gas appliances

Decorative fuel-effect gas appliances

This document specifies the requirements and test methods for the construction, safety, and marking of decorative fuel effect gas appliances not exceeding a nominal heat input of 20 kW (based on the net calorific value), thereafter referred to as appliances.
This document is applicable to appliances that are designed to simulate a solid fuel fire and incorporate a natural draught burner with or without an ignition burner, that uses one or more combustible gases of the three gas families at the pressures stated in EN 437:2021. The appliances are for decorative purposes only and are not heating appliances.
This document is applicable to type BAS, as described in 4.2, decorative fuel effect gas appliances that are designed to be installed within a non-combustible builder's opening or a non-combustible fireplace recess.
This document specifies special national conditions in Annex C for appliances of category I2E+, marketed in Belgium.
This document specifies special A-deviations in Annex D for appliances in Switzerland which require additional requirements for subclauses 6.6 and 6.7. This document includes additional requirements for Type BBS appliances which are specified in Annex F.
In addition, this document is applicable to decorative fuel-effect gas appliances that are designed to be installed under a non-combustible canopy which is independent or integral with a flue box, for which additional requirements are specified in Annex A.
The use of toxic gases is not covered.
This document is not applicable to:
-   catalytic combustion appliances;
-   appliances in which the supply of combustion air and/or the evacuation of products of combustion is achieved by mechanical means.
NOTE   Requirements concerning the rational use of energy have not been included in this document because the appliances are for decorative purposes.

EN 15502-2-2:2024

This document 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 intended to be read as the boiler including its connecting ducts, ducts and terminals, if any.
This document covers gas-fired central heating boilers type B11, B11BS, B12, B12BS, B13, B13BS:
NOTE 1   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 437:2021;
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.
NOTE 2   This document provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this document, 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 document does not cover all the requirements for:
aa)   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);
ab)   appliances using flue dampers;
ac)   appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW;
ad)   appliances of the types A, B14, B¬2, B3, B4, B5 and C;
ae)   appliances intended to be connected to a (common) flue having mechanical extraction;
af)   appliances with gas/air ratio control;
ag)   modular boilers;
ah)   boilers which can give rise to condensation under certain circumstances;
ai)   boilers intended to be installed in a room with a foreseeable negative pressure relative to the pressure in the flue system;

al)   boilers intended to be installed in areas accessible to elderly people and children;
am)   boilers equipped with an adaptive combustion control function (ACCF).
NOTE   Negative pressure relative to the pressure in the flue system can for example be caused by mechanical or thermal ventilation in airtight buildings.

This European Standard only covers water heaters where the fan, if any, is an integral part of the appliance.
This European Standard:
-   does not apply to appliances not intended to be connected to a flue when they are not fitted with an atmosphere sensing device;
-   takes account of the information given in Technical Report CEN/CR 1472:1994 with respect to marking.
Type B appliances should be with a combustion products discharge safety device to comply with essential requirement 3.4.3 of the Gas Appliances Directive 2009/142/EC. In this European Standard, the appliance is identified as type B11BS.
Appliances intended to be installed outdoors or in a room separate from inhabited rooms and provided with appropriate ventilation are not required to have this combustion products discharge safety device but, in this case, appropriate warnings on the packaging, and in the instructions should clearly define the limited authorized use for this type of appliance.

Gas-fired central heating boilers - Part 2-3: Specific standard for hybrid units combining a gas fired boiler and an electrical heat pump in a product
EN 15502-2-3:2023

This document specifies the requirements and tests methods concerning the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of hybrid units.
A hybrid unit is composed of:
-   a gas boiler as a heat generator which is able to supply the heat demand in all operating conditions;
-   an electrical air-to-water heat pump, as a heat generator, which does not have to meet the heat demand in all operating conditions;
-   a control unit (see definition 3.1.10).
A hybrid unit can include the facility to produce hot water, either by the instantaneous or storage principle, the whole being marketed as a single unit.
A gas boiler as part of a hybrid unit covered by this document is a gas-fired central heating boiler from the types C1 up to C9 and the types B2, B3 and B5, according to the classification in EN 1749:2020:
a)   that have a nominal heat input (on the basis of gross calorific value) not exceeding 400 kW;
b)   that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021;
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 classified as a gas-fired central heating boiler;
f)   which are intended to be installed either indoors or outdoors in a partially protected place;
g)   which are designed for either sealed water systems or for open water systems.
This document provides requirements for boilers with known constructions.
NOTE 1   For boilers with any alternative constructions, which might not fully be covered by this document, the risk associated with this alternative construction needs to be assessed.
NOTE 2   An example of an assessment methodology, based upon risk assessment and which covers the essential requirements of the Gas Appliance Regulation UE/426/2016, is given in Clause 11.
This document does not cover all the requirements for:
aa)   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 EN 15502-1:2021, Annex AB);
ab)   appliances using flue dampers;
ac)   appliances of the types B21, B31, B51, C21, C41, C51, C61, C71 and C81;
ad)   appliances incorporating flexible plastic flue liners;
ae)   appliances designed to become connected to a combined flue duct system.
af)   appliances of the types C(10),C(11), C(12) and C(13);
ag)   C7 appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW;
ah)   appliances intended to be connected to a flue having mechanical extraction;
