Specification for Dedicated Liquefied Petroleum Gas Appliances - Domestic Flueless Space Heaters (Including Diffusive Catalytic Combustion Heaters)
Also Known As:
For household flueless space heaters, the DIN EN 449 standard specifies a set of specifications and test procedures. These heaters feature a nominal heat input (Hs) that does not exceed 4.2 kW and incorporate diffusive catalytic combustion heaters.
The standard is focused on equipment that burns gases from the third family at nominal operating pressures no greater than 50 mbar. It outlines the requirements that must be satisfied by the heaters in order to guarantee their performance and safety. This covers the specifications for the materials to be utilized as well as the demands for heat production, emissions, and thermal stability.
The DIN EN 449 standard also specifies the testing procedures to be used to confirm conformity with the requirements. These testing processes are necessary to assess the heater's functionality, effectiveness, and safety features. When a heater has satisfactorily complied with all the requirements and completed the necessary tests, it can be tagged to show that it complies with the standard.
