The change A1 of EN 1596 concerns several technical amendments due to need for regulation appearing after ratification of the standard. The standard itself defines for the purpose of type approval the safety characteristics, the test methods and the marking of mobile, non-domestic forced convection direct fired air heaters with a nominal heat input of up to 180 kW (HS) for the combustion of 3rd family gases (liquefied petroleum gases). Most significant technical change stipulated by this draft ist the lowering of the air delivery temperature from 80 °C to 55 °C.
This document specifies, for the purpose of type examination, the requirements and test methods for construction, safety, marking and rational use of energy of 2ne and 3rd family gas-fired domestic flueless space heating appliances having a nominal input not exceeding 6 kW (based on net calorific value). It covers the following Type AAS fixed flueless heaters: NOTE These are type A appliances fitted with an atmosphere sensing device, with or without a fan. a) heaters with or without a catalytic converter; b) Category 1 appliances burning gases of the second family; c) Category 2 appliances burning gases of the second and third families. It does not cover qi. Mobile heaters.ii. Category 1 appliances burning gases of the third family.iii. Portable flueless heaters.iv. Diffusive catalytic combustion heaters. There are no specific thermal efficiency requirements appropriate to these types of appliance as: -- All the heat produced by the combustion process is released into the space to be heated. -- The requirements with regard to the combustion performance, which is a safety matter, ensure the effective burning of the fuel gas. This standard is only applicable to appliances which are to be type tested. Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by this standard.
