This European Standard specifies the requirements and test methods for the safety and efficiency of nondomestic gas-fired air heaters not exceeding a net heat input of 300 kW with (an) atmospheric burner(s) and without a fan to assist the transportation of combustion air and/or flue gases, hereafter referred to as "appliances". This European Standard applies to Type B11, B41, C11 and C31 appliances intended for use in other than single unit residential dwellings. Provision of the heated air may be by means of ducting or may be directly into the heated space.
