This document specifies the construction and performance characteristics related to safety and the rational use of energy of portable appliances burning liquefied petroleum gases at the vapour pressure within the gas cartridge or gas cylinder, excepting those where the gas cartridge is inserted horizontally in the chassis.
NOTE   These appliances are referred to in the body of the text as "appliances".
This document applies to various types of portable appliances burning liquefied petroleum gases at vapour pressure and designed to be used with cartridges as complying with EN 417 or gas cylinders.
This document covers appliances for outdoor or in well ventilated areas uses only.
For example the following types of appliances are covered:
a)   cooking appliances (stoves, grills, barbecues...);
This document does not cover barbecues that can be used indoors;
b)   lighting appliances;
c)   heating appliances;
This document only applies to appliances with a maximum heat input of up to 3 kW (Hs) for outdoor use only;
d)   blowtorches;
This document only applies to blowtorches without a flexible hose;
e)   laboratory burners.
The requirements apply to these appliances or their functional sections whether or not the latter are independent or incorporated into an assembly.
Appliances covered by this document are not connected to a flue for the discharge of products of combustion and are not connected to the mains electricity supply.
This document covers neither appliances supplied with LPG in the liquid phase nor appliance with fixed integral container which may or may not be refilled by the user
It does not apply to lighters as defined in EN ISO 9994.
It does not apply to gas appliances operating with a valve cartridge which is horizontally integrated into the chassis of the appliance also called "flat portable gas stove".
Requirements for rational use of energy have been included for stove burners.
However, such requirements have not been included for the other types of appliances because:
-   for grills and barbecues, this is a type of cooking which is achieved by various means such as radiant elements; in addition this type of cooking varies according to the type of food and region where the appliance is used;
-   for lighting appliances, the consumption is insignificant because these appliances have a very low rate and are used only for a few hours in a year;
-   for heating appliances, all the heat produced is discharged into the environment;
-   for tools such as blowtorches which are not professional tools in regular use, the gas consumption depends very much on the way it is used.

This European Standard specifies the common requirements and test methods concerning, in particular the construction, safety, fitness for purpose, and rational use of energy, as well as the classification, marking and energy labelling 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.
This European Standard is to be used in conjunction with the specific Parts 2 (Part 2-1 and following ones).
This European Standard applies to boilers of types B and C, according to CEN/TR 1749:2014
a)   that use one or more combustible gases of the three gas families at the pressures stated in EN 437 ;
b)   where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation;
c)   where the maximum operating pressure in the water circuit does not exceed 6 bar;
d)   which can give rise to condensation under certain circumstances;
e)   !which are declared in the installation instructions to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler" or an "other boiler". If no declaration is given the boiler is to be considered both a "standard boiler" and an "other boiler";
NOTE   The Ecodesign Directive defines "other boilers", "low temperature boilers" and "condensing boilers". The Boiler Efficiency Directive defines "standard boilers", "low temperature boilers" and "condensing boilers". Depending on the legislation applied, a boiler can be both "a standard boiler" and an "other boiler"."
f)   which are intended to be installed inside a building or in a partially protected place;
g)   which are intended to produce hot water either by the instantaneous or storage principle, the whole being marketed as a single unit.
This European Standard applies to boilers designed for sealed water systems or for open water systems.
This general standard and the specific standards (see Part 2) provide requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard or a specific standard, the risk associated with this alternative construction will need to be assessed.
An example of an assessment methodology, based upon risk assessment, is given in Clause 11.
This European Standard is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance.

Appliances covered by these standards include one or a combination of the following:
   gas fired sorption chiller;
   gas fired sorption chiller/heater;
   gas fired sorption heat pump;
These standards apply to appliances only when used for space heating and cooling with or without heat recovery. Appliances can be monovalent, bivalent or hybrid types.
These standards apply to appliances having flue gas systems of type B and C (according to the CEN/TR 1749) and to appliances designed for outdoor installations. These European Standards apply to appliances that can be single ducted or double ducted.
These standards only apply to appliances having:
   integral burners under the control of fully automatic burner control systems;
   closed system refrigerant circuits in which the refrigerant does not come into direct contact with the water or air to be cooled or heated;
   mechanical means to assist transportation of the combustion air and/or the flue gas.
The above appliances can have one or more primary or secondary functions (i.e. heat recovery - see definitions prEN 12309-1:2012) and this standard applies to all such functions providing that the function concerned is dependent on circulation of fluid (refrigerant and/or solution) within the absorption, adsorption or refrigerant circuit(s).
NOTE 1   Any appliance function that is not dependent on circulation of the fluid within the absorption, adsorption, or refrigerant circuit(s) is assessed separately.
These standards are applicable to appliances that are intended to be type tested. Requirements for appliances that are not type tested would need to be subject to further consideration.
In the case of packaged units (consisting of several parts), the standard applies only to those designed and supplied as a complete package.
These standards do not apply to air conditioners.
The appliances having their condenser cooled by air and by the evaporation of external additional water are not covered by this standard.
Installations used for heating and/or cooling of industrial processes are not within the scope of these standards.
NOTE 2   All the symbols given in this text are used regardless of the language used.
