Specification for dedicated liquefied petroleum gas appliances - Flueless non-domestic space heaters not exceeding 10 kW

This European Standard defines requirements and test methods concerning, in particular, the construction, safety as well as classification and marking of non-domestic flueless space heaters (including greenhouse heaters and diffusive catalytic combustion heaters), having a nominal heat input not exceeding 10 kW (Hs) burning 3rd family gases at nominal operating pressure not exceeding 50 mbar, referred to in the body of the text as 'appliances'. It covers the following types of appliance: a) fixed heaters; b) portable or mobile heaters including those that incorporate a compartment for a transportable refillable LPG cylinder.

Festlegungen für Flüssiggasgeräte - Abzuglose Gewerberaumheizgeräte bis zu 10 kW

Der ganze Abschnitt ist zu streichen und durch den folgenden Abschnitt zu ersetzen:
?Diese Europäische Norm legt insbesondere die Anforderungen und die Prüfverfahren für die Konstruktion, die Sicherheit fest, die Klasseneinteilung und die Kennzeichnung von abzuglosen Gewerbe-Raumheizgeräten (einschließlich Gewächshausheizgeräte und Heizgeräte mit katalytischer Verbrennung), mit einer Nennwärmebelastung, die 10 kW (HS) nicht überschreitet, die mit Gasen der dritten Gasfamilie bei einem Nenndruck von nicht mehr als 50 mbar betrieben werden und im nachfolgenden Text als ?Geräte" bezeichnet werden.
Sie behandelt folgende Arten von Geräten:
a) fest installierte Heizgeräte;
b) tragbare oder ortsveränderliche Heizgeräte einschließlich derjenigen Heizgeräte, die ein Einstellfach für eine transportable und nachfüllbare  Flüssiggasflasche haben;
c) Heizgeräte, die nicht in häuslicher Umgebung verwendet werden;
d) Heizgeräte, die allein im Freien verwendet werden.
ANMERKUNG 1   Flüssiggasheizgeräte für die Verwendung in häuslicher Umgebung und mit einer 4,2 kW nicht überschreitenden Nennwärmebelastung werden in EN 449 behandelt.
ANMERKUNG 2   Gasgeräte-Heizstrahler werden in EN 416-1 behandelt.
Für diese Arten von Geräten gibt es keine Anforderungen an den spezifischen Wärmewirkungsgrad, weil
3 die gesamte, beim Verbrennungsvorgang erzeugte Wärme in den zu beheizenden Raum geführt wird;
3 die Anforderungen an die Qualität der Verbrennung, die eine Sicherheitsanforderung ist, eine vollständige Verbrennung des Flüssiggases sicherstellen.
Diese Norm gilt nicht für Geräte mit einem Gebläse für die Unterstützung der Verbrennung oder für die Umwälzung der erwärmten Luft. Auch Geräte mit vollautomatischen Regeleinrichtungen fallen nicht unter diese Norm.
Diese Norm gilt nicht für Geräte zur Beheizung von Gebäuden für die Tieraufzucht (siehe EN 12669).
Die in dieser Norm aufgeführten Anforderungen an die Geräte setzen voraus, dass die Gaszufuhr von einem Druckregler überwach

1 Scope
Delete the whole clause and replace it with the following:

“This European Standard defines requirements and test methods concerning, in particular, the construction, safety

as well as classification and marking of non-domestic flueless space heaters (including greenhouse heaters and

diffusive catalytic combustion heaters), having a nominal heat input not exceeding 10 kW (H ) burning 3 family

gases at nominal operating pressure not exceeding 50 mbar, referred to in the body of the text as 'appliances'.

It covers the following types of appliance:
a) fixed heaters;

b) portable or mobile heaters including those that incorporate a compartment for a transportable refillable

liquefied petroleum gas cylinder;
c) heaters intended for use in non domestic areas;
d) heaters intended solely for outdoor use.

NOTE 1 LPG appliances having a nominal heat input not exceeding 4,2 kW and intended for use in domestic premises are

covered by EN 449.
NOTE 2 Overhead radiant heater appliances are covered by EN 416-1.

There are no specific thermal efficiency requirements appropriate to these types of appliances as:

 all the heat produced by the combustion process is released into the space to be heated;

 the requirements with regard to the combustion performance, which is a safety matter, ensure the effective

burning of the fuel gas.

This standard does not apply to appliances which incorporate a fan for either the assistance of combustion or the

circulation of convected air. Neither does it cover appliances incorporating full sequence automatic controls.

This standard does not apply to appliances for heating buildings used for animals rearing (see EN 12669).

Requirements for appliances given in this standard assume that the supply of gas will be controlled by a pressure

regulator giving an outlet pressure as indicated in Table A.1.

Requirements for controls, given herein, relate to controls fitted as part of, or supplied with, particular appliances;

they do not necessarily provide a complete specification for controls intended for general use.

NOTE 3 Catalytic heaters are not considered suitable for use in areas having chemicals present which are likely to prevent

the correct operation of the catalytic pad.

This standard does not cover cylinders for liquefied petroleum gases or their associated regulators, which shall

comply with national requirements in force.
This European Standard only covers type testing.”
