(Main)Gas-fired central heating boilers - 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
Gas-fired central heating boilers - 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
This European Standard specifies, the requirements and test methods concerning, in particular, the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”.
Where the word boiler is used, it needs to be read as the boiler including its connecting ducts, ducts and terminals, if any.
This European Standard covers gas-fired central heating boilers from the types C1 up to C9 and the types B2, B3 and B5:
NOTE For further background information on appliance types see CEN/TR 1749:2014."
a) that have a nominal heat input (on the basis of net calorific value) not exceeding 1 000 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437;
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 may or may not give rise to condensation under certain circumstances;
f) which are declared in the installation instructions to be either a “condensing” boiler or a "low temperature boiler" or a “standard boiler”; if no declaration is given the boiler is to be considered a “standard boiler”;
g) which are intended to be installed either indoors or outdoors in a partially protected place;
h) which may include the facility to produce hot water, either by the instantaneous or storage principle, the whole being marketed as a single unit;
i) which are designed for either sealed water systems or for open water systems;
j) which are either modular boilers, or non- modular boilers.
This European Standard also covers gas-fired condensing central heating boilers from the types C(10) that are equipped with a gas-air ratio control and that have a Δpmax, saf(min) of 25 Pa, and C(11) boilers that have condensing boiler modules that are equipped with a gas-air ratio control and that have a Δpmax, saf(min) of 25 Pa."
This European 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 and which covers the essential requirements of the Gas Appliance Directive, is given in Clause 11.
This European Standard specifies, the requirements and test methods concerning, in particular, the construction, safety, fitness for purpose, and rational use of energy, as well as the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as “boilers”.

Plinski kotli za centralno gretje - 2-1. del: Poseben standard za tip kotlov C in tipe kotlov B2, B3 in B5 z imensko močjo do vključno 1000 kW (vključno z dopolnilom A1)
Ta evropski standard določa zahteve in preskusne metode zlasti v zvezi s konstrukcijo, varnostjo, ustreznostjo za predvideni namen in smiselno porabo energije ter z razvrstitvijo in označevanjem plinskih kotlov za centralno gretje z nameščenimi atmosferskimi gorilniki, atmosferskimi gorilniki z ventilatorjem ali gorilniki s popolnim vnaprejšnjim mešanjem (v nadaljevanju »kotli«).
Kjer je uporabljena beseda kotel, to pomeni kotel skupaj s povezovalnimi vodi, vodi in priključki, če so prisotni.
Ta evropski standard zajema plinske kotle za centralno gretje tipov od C1 do C9 ter tipov B2, B3 in B5:
OPOMBA: Za dodatne informacije o tipih kotlov glej standard CEN/TR 1749:2014.
a) z nazivno močjo (glede na neto kurilno vrednost) do vključno 1000 kW;
b) ki uporabljajo enega ali več gorljivih plinov iz treh družin plinov pri tlakih, navedenih v standardu EN 437;
c) pri katerih temperatura tekočine za prenos toplote pri običajnem delovanju ne presega 105 °C;
d) pri katerih najvišji obratovalni tlak v vodnem omrežju ne presega 6 barov;
e) ki lahko pod določenimi pogoji povzročijo kondenzacijo;
f) ki so v navodilih za namestitev deklarirani kot »kondenzacijski kotli« ali »nizkotemperaturni kotli« ali »standardni kotli«; če ni navedene deklaracije, se kotel upošteva kot »standardni kotel«;
g) ki so namenjeni notranji ali zunanji namestitvi v delno zaščitenem prostoru;
h) ki lahko vključujejo tudi funkcijo ogrevanja vode po načelu pretočnosti ali po načelu shranjevanja, pri čemer se trži kot ena enota;
i) ki so izdelani za zaprte vodne sisteme ali odprte vodne sisteme;
j) ki so lahko modularni ali nemodularni kotli.
Ta evropski standard zajema tudi plinske kondenzacijske kotle za centralno gretje tipa C(10), ki so opremljeni z nadzorom razmerja med plinom/zrakom in pri katerih je Δpmax, saf(min) 25 Pa, ter kotle tipa C(11) z moduli kondenzacijskih kotlov, ki so opremljeni z nadzorom razmerja med plinom/zrakom in pri katerih je Δpmax, saf(min) 25 Pa.
Ta evropski standard podaja zahteve za kotle z znanimi konstrukcijami. V zvezi s kotli z drugačnimi konstrukcijami, ki morda niso v celoti zajeti v tem standardu, je treba oceniti tveganje, povezano z drugačno konstrukcijo.
Primer metodologije ocenjevanja, ki temelji na oceni tveganja in zajema osnovne zahteve direktive o plinskih napravah, je podan v točki 11.
Ta evropski standard določa zahteve in preskusne metode zlasti v zvezi s konstrukcijo, varnostjo, ustreznostjo za predvideni namen in smiselno porabo energije ter z razvrstitvijo in označevanjem plinskih kotlov za centralno gretje z nameščenimi atmosferskimi gorilniki, atmosferskimi gorilniki z ventilatorjem ali gorilniki s popolnim vnaprejšnjim mešanjem (v nadaljevanju »kotli«).
