Non-domestic gas-fired overhead luminous radiant heaters - Part 1: Safety
This European Standard specifies the requirements and test methods for the construction, safety, classification and marking of non-domestic gas-fired overhead luminous radiant heaters for environmental comfort, incorporating an atmospheric burner system referred to in the body of the text as "appliances". This European Standard is applicable to Type A1 and Type B11 appliances only (see 4.3). This European Standard is not applicable to: - appliances designed for use in domestic dwellings; - outdoor appliances; - appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference gas); - appliances having fully pre-mixed gas and air burners in which : - either the gas and all the combustion air are brought together just before the level of the combustion zone; - or the pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of the combustion zone. - appliances in which the supply of combustion air and/or the removal of the products of combustion is achieved by integral mechanical means. This standard is applicable to appliances which are intended to be type tested. Requirements for appliances which are not intended to be type tested would need to be subject to further consideration. Requirements concerning the rational use of energy have not been included in this European Standard.
