This European Standard gives guidelines for environmental aspects (see Annex N).
This European Standard does not apply to mechanical controls for use with liquid fuels.
The protection against environmental impact in open air (i.e. capable of withstanding UV radiation, wind, rain, snow, dirt deposits, condensation, ice and hoar frost (see IEV 441-11-05:2005), earthquake and external fire) is not covered by this standard.
This European Standard should be used in conjunction with the specific control standard (see Bibliography).

This European standard specifies the design, safety and marking requirements and test methods for flueless patio heaters for outdoor or amply ventilated area use only.
These appliances are for use exclusively with gases of the third family as defined in Clause 4.
This European standard applies to appliances that have a nominal heat input not exceeding 17 kW (based on the gross calorific value), supplied with a maximum inlet pressure of 50 mbar:
-   fixed or,
-   movable, including those which comprise a housing for a transportable and rechargeable liquefied petroleum gas cylinder.
This European standard does not apply to appliances equipped with a fan for either combustion or circulation of the convection air.
This European standard does not cover LPG containers for liquefied petroleum gas, their associated regulator, tubing and flexible hoses used for gas supply of appliances covered by this European standard. Regulator, tubing and flexible hoses are covered by others standards (EN 16129, EN 16436-1 and prEN 16436-2, etc.) and national regulations.
This European standard does not lay down any specific requirements for the thermal efficiency of this type of appliances, but the requirements relating to combustion, which is a safety matter, ensure that the gas fuel will burn efficiently. However a method to measure the performance is described in informative Annex B.
