Open fronted gas-fired independent space heaters
This European Standard specifies the requirements and test methods for the construction, safety, marking and rational use of energy of open fronted gas-fired independent space heaters with and without a fan to assist with the transportation of flue gases, hereafter referred to as appliances. Although the fan may be mounted outdoors, this standard only covers appliances where the body of the appliance is indoors. This standard applies to types B11AS, B11BS, B14AS, and B14BS (commonly referred to in this standard as type B1 appliances) open fronted gas-fired independent space heating appliances: - that incorporate an atmospheric burner; - that are connected directly to an open flue (see Figure 1), or to a device to evacuate the products of combustion (open-flued appliances); - that have a nominal heat input not exceeding 20 kW (based on the net calorific value); - that are delivered with the gas-carrying components, burner(s), combustion chamber and heat exchanger fully assembled. It does not apply to: - closed-fronted appliances; - decorative fuel effect appliances as specified in EN 509; - catalytic combustion appliances; - ducted-air appliances; - appliances installed by means of a closure plate.
Konvektions-Raumheizer für gasförmige Brennstoffe mit offener Verbrennungskammer
Diese Europäische Norm legt Anforderungen und Prüfbestimmungen für Bau, Sicherheit, Kennzeichnung und rationelle Energienutzung von Konvektions-Raumheizern für gasförmige Brennstoffe mit offener Verbrennungskammer fest mit und ohne Ventilator für den Abtransport der Abgase, im Folgenden als Gerät bezeichnet. Obwohl der Ventilator auch im Freien angebracht sein kann, deckt diese Norm nur die Nutzung des Gerätes, wenn die Teile in Räumen aufgestellt sind.
Sie gilt für gasbeheizte Konvektions-Raumheizer mit offener Verbrennungskammer der Arten B11AS, B11BS, B11CS;, B14AS und B14BS (in dieser Norm B1 genannt) für gasförmige Brennstoffe mit Verbrennungskammer,
die mit atmosphärischem Brenner geliefert werden,
die direkt an einen Schornstein oder an eine Einrichtung zur Abführung der Abgase angeschlossen sind (schornsteingebundene Geräte), siehe Ziffer 1,
die eine Nennwärmebelastung unter 20 kW (bezogen auf den Heizwert) haben und
die komplett mit gasführenden Komponenten, Brenner(n), Verbrennungskammer und Wärmeaustauscher geliefert werden.
Die vorliegende Europäische Norm gilt nicht für
Geräte mit geschlossener Verbrennungskammer,
Geräte mit dekorativem Brennstoffeffekt gemäß prEN 509;
Geräte mit katalytischer Verbrennung;
Warmlufterzeuger;
Geräte, die mit einer Verschlussplatte installiert werden (siehe 3.3.3.3).
Appareils de chauffage indépendants à foyer ouvert utilisant les combustibles gazeux
La présente Norme européenne définit les exigences et méthodes d'essais pour la construction, la sécurité, le marquage et l'utilisation rationnelle de l'énergie des appareils des appareils de chauffage indépendants à foyer ouvert utilisant les combustibles gazeux, avec ou sans ventilateur pour faciliter le transport des gaz de cheminée, appelés ci-après « appareils ». Bien que le ventilateur puisse être monté à l’extérieur, cette norme ne couvre que les appareils dont le corps se trouve à l’intérieur.
La présente norme s'applique aux appareils de chauffage indépendants à foyer ouvert utilisant les combustibles gazeux de types B11AS, B11BS, B14AS et B14BS, (communément appelés appareils de type B1 dans la présente norme) :
qui intègrent un brûleur atmosphérique ;
qui sont directement raccordés à un conduit de cheminée ouvert (voir Figure 1) ou à un dispositif d'évacuation des produits de combustion (appareils à conduit de cheminée ouvert) ;
de débit calorifique nominal inférieur ou égal à 20 kW (sur la base du pouvoir calorifique inférieur) ;
qui sont fournis avec les composants du circuit gaz, les brûleurs, la chambre de combustion et l'échangeur thermique complètement assemblés.
La présente norme ne s'applique pas :
aux appareils à foyer fermé ;
aux appareils à effet décoratif de combustion comme spécifié dans l'EN 509 ;
aux appareils à combustion catalytique ;
aux appareils de distribution d'air par gaine ;
aux appareils installés au moyen d'une plaque de fermeture (voir 3.3.3.3).
Prostostoječi plinski grelniki prostorov z odprtim kuriščem
Ta evropski standard določa zahteve in preskusne metode za izdelavo, varnost, označevanje in racionalno porabo energije prostostoječih plinskih grelnikov prostorov z odprtim kuriščem z ventilatorjem in brez njega, ki pomagajo pri prenosu dimnih plinov, v nadaljnjem besedilu: aparati. Čeprav je lahko ventilator nameščen zunaj, se ta standard uporablja samo za aparate, pri katerih se osrednji del nahaja znotraj. Ta standard se uporablja za prostostoječe plinske grelnike prostorov z odprtim kuriščem tipov B11AS, B11BS, B14AS in B14BS (ki se v tem standardu splošno imenujejo aparati tipa B1): – ki vključujejo atmosferski gorilnik; – ki so neposredno povezani z odprto odvodno cevjo (glej sliko 1) ali z napravo za odvajanje produktov zgorevanja (naprave z odprto odvodno cevjo); – z nazivnim dovodom toplote pod 20 kW (na podlagi neto kalorične vrednosti); – ki se dobavljajo z v celoti sestavljenimi sestavnimi deli, ki odvajajo plin, gorilnikom(-i), zgorevalno komoro in toplotnim prenosnikom. Ne uporablja se za: – aparate z zaprtim kuriščem; – plinske aparate z dekorativnim plamenom iz standarda EN 509; – aparate s katalitičnim izgorevanjem; – aparate z vodenim zrakom; – aparate, vgrajene z zapiralno ploščo.
