Residential solid fuel burning appliances - Part 2-6: Mechanically by wood pellets fed roomheaters, inset appliances and cookers

This document is applicable to mechanical by wood pellets fed roomheaters, inset appliances and cookers up to 50 kW nominal heat output.
The intended use of the appliances is space heating in residential buildings and can be cooking. They can be fitted with a boiler (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems.
These appliances typically use auxiliary energy which is measured in this document as well. They can be operated with either natural draught or fan-assisted combustion air.
NOTE   A fan-assisted appliance does still operate under negative pressure in the flue gas system.
These appliances burn wood pellets only as specified. They only operate with the firedoors closed.
This document is not applicable to appliances:
-   with boiler intended for water systems having water temperatures above 110 °C and 3 bar;
-   with boiler intended for water systems having direct contact with sanitary hot water;
-   intended to be used with a pure horizontal exhaust (through the building wall);
-   with flue gas condensation in the appliance;
-   switching on/off for part load operation.
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of mechanical by wood pellets fed roomheaters, inset appliances and cookers.

Häusliche Feuerstätten für feste Brennstoffe - Teil 2-6: Mechanisch mit Holzpellets beschickte Raumheizer, Einsätze und Herde

Dieses Dokument ist anwendbar auf mechanisch mit Holzpellets beschickte Raumheizer, Einsätze und Herde mit einer Nennwärmeleistung bis 50 kW.
Der Verwendungszweck der Geräte ist Raumheizung in Wohngebäuden und kann das Kochen sein. Sie können mit wasserführenden Bauteilen (als feste Bestandteile des Gerätes mit zu erhitzendem Wasser) zur Warmwasserbereitung der Zentralheizung ausgestattet sein.
Diese Geräte verwenden typischerweise Hilfsenergie, die ebenfalls in diesem Dokument bestimmt wird. Sie können mit natürlichem Förderdruck oder mit gebläseunterstützter Verbrennungsluftzufuhr betrieben werden.
ANMERKUNG    Eine gebläseunterstützte Feuerstätte arbeitet bei Unterdruck im Abgassystem.
Diese Geräte verfeuern nur entsprechend spezifizierte Holzpellets. Sie werden nur mit geschlossenen Feuerraumtüren betrieben.
Dieses Dokument ist nicht anzuwenden für Geräte:
—   mit wasserführenden Bauteilen vorgesehen für Wassersysteme mit einer Wassertemperatur über 110 °C und 3 bar;
—   mit wasserführenden Bauteilen vorgesehen für Wassersysteme mit direktem Kontakt zu Brauchwarmwasser;
—   die für den Betrieb mit direkter horizontaler Abgasführung (durch die Gebäudewand) vorgesehen sind;
—   mit Abgaskondensation in der Feuerstätte;
—   mit an- und ausschaltendem Teillast-Betrieb.
Dieses Dokument legt das Verfahren für die Bewertung und Überprüfung der Leistungsbeständigkeit (AVCP) der Eigenschaften von mechanisch mit Holzpellets beschickten Raumheizern, Einsätzen und Herden fest.

Appareils de chauffage domestiques à combustible solide - Partie 2-6 : Poêles, inserts et cuisinières à granulés de bois et à alimentation mécanique

Le présent document s'applique aux poêles, inserts et cuisinières à granulés de bois et à alimentation mécanique, de puissance utile nominale inférieure ou égale à 50 kW.
L'usage prévu des appareils est le chauffage des locaux dans les bâtiments résidentiels et éventuellement la cuisson. Ils peuvent être équipés d'un bouilleur (faisant partie intégrante de l'appareil et contenant de l'eau à chauffer) pour fournir de l’eau chaude aux systèmes de chauffage central.
Ces appareils utilisent généralement de l’énergie auxiliaire, qui est également mesurée dans le présent document. Ils peuvent fonctionner en tirage naturel ou être équipés d’un ventilateur pour l’alimentation en air de combustion.
Ces appareils utilisent uniquement des granulés de bois spécifiés. Ils ne fonctionnent qu’avec les portes foyères fermées.
NOTE   Un appareil équipé d’un ventilateur fonctionne toujours avec un conduit de fumées soumis à une pression négative.
Le présent document ne s’applique pas aux appareils :
-   à bouilleur prévu pour les circuits d’eau dont la température d’eau est supérieure à 110 °C 3 bar ;
-   à bouilleur prévu pour les circuits d’eau en contact direct avec de l’eau chaude sanitaire ;
-   prévus pour une utilisation avec une évacuation purement horizontale (directement à travers le mur du bâtiment) ;
-   à condensation des fumées dans l’appareil ;
-   à commutation marche/arrêt pour un fonctionnement à charge partielle.
Le présent document spécifie des modes opératoires pour l'évaluation et la vérification de la constance des performances (EVCP) des caractéristiques des poêles, inserts et cuisinières à granulés de bois et à alimentation mécanique.

1 Scope

This document is applicable to space heaters, inset appliances and cookers fired by wood pellets,

mechanically fed up to 50 kW nominal heat output. These appliances typically use auxiliary energy which

is measured in this document as well.

For inset pellet appliances and especially their testing, additional information from

prEN 16510-2-2:2021 is relevant.

For pellet cookers and especially their testing, additional information from prEN 16510-2-3:2021 is

relevant.

Non-mechanically fed appliances burning solid mineral fuels, peat briquettes and natural or

manufactured wood logs are not included in this document, but are covered by prEN 16510-2-1:2021 to

prEN 16510-2-5:2021.

NOTE 1 These appliances could have an integral fuel hopper or be combined with an external fuel hopper.

This document is used in conjunction with prEN 16510-1:2021.

The appliances covered by this document provide heat into the space where they are installed. They can

be operated with either natural draught or fan-assisted combustion air. Where fitted with a boiler, they

can also provide domestic hot water and/or central heating. These appliances burn wood pellets only, in

accordance with the appliance manufacturer's instructions. They only operate with the firedoors closed.

NOTE 2 A fan-assisted appliance does still operate under negative pressure in the flue gas system.

This document specifies requirements relating to the design, manufacture, construction, safety and

performance (efficiency and emissions), instructions and marking together with associated test methods

and test fuels.
This document is not applicable to appliances:

— with boiler intended for water systems having water temperatures above 110°C and 3 bar;

— with boiler intended for water systems having direct contact with sanitary hot water;

— intended to be used with a pure horizontal exhaust (through the building wall);

— with flue gas condensation in the appliance;
— switching on / off for part load operation.

necessary with the following modification(s).
6.2.2 Flue gas temperature at safety test
prEN 16510-1:2021, 6.2.2 shall be applicable with the following modification(s).
Replace 6.2.2 by the following:

When tested in accordance with A.4.10.3 the flue gas temperature shall be measured and the mean value

of the last 30 min of the test is determined. This value shall not exceed the designated Tclass of the

chimney. The chimney designation shall be at least T200 G.

NOTE National installation and building regulations are expected to be met in this particular item (often a T400

G is required in these regulations)
6.3.5 Particulate matter (PM/PME) emissions
prEN 16510-1:2021, 6.3.5 shall be applicable with the following modification(s).
Replace 6.3.5 by the following:

At all heat output rates specified by the manufacturer the mean particulate matter concentration

expressed as mg/m3 for PM/PME calculated to 13 % oxygen (O ) content, (dry, 273 K, 1 013 hPa) in the

flue gas is measured, and it shall be less than or equal to the manufacturer’s specified value expressed in

mg/m .

During each nominal test measure the PM/PME according to the following procedure:

— 30 min operation without measurement;
— 30 min filter 1st sampling and appropriate analysis;

— 30 min operation without measurement (filter may be exchanged in that period);

— 30 min filter 2nd sampling and appropriate analysis;

— 30 min operation without measurement (filter may be exchanged in that period);

— 30 min filter 3rd sampling and
