This document specifies, for the purpose of type examination, the requirements and test methods for construction, safety, marking and rational use of energy of 2nd 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:NOTEThese 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 i.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.
