26、truction, 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 A1appliances only (see 4.3)

27、. This European Standard is not applicable to: a) appliances designed for use in domestic dwellings; b) outdoor appliances; c) appliances of heat input in excess of 120 kW (based on the net calorific value of the appropriate reference gas); d) appliances having fully pre-mixed gas and air burners in

28、 which: 1) either the gas and all the combustion air are brought together just before the level of the combustion zone; or 2) the pre-mixing of the gas and all combustion air is carried out in a part of the burner upstream of the combustion zone; e) appliances in which the supply of combustion air a

29、nd/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. Requiremen

43、onveys or contains the gas between the appliance gas inlet connection and the burner(s) 3.1.6 restrictor device with an orifice, which is placed in the gas circuit so as to create a pressure drop and thus reduce the gas pressure at the burner to a predetermined value for a given supply pressure and

44、rate 3.1.7 gas rate adjuster component allowing an authorized person to set the gas rate of the burner to a predetermined value according to the supply conditions NOTE 1 Adjustment can be progressive (screw adjuster) or in discrete steps (by changing restrictors). NOTE 2 The adjusting screw of an ad

45、justable regulator is regarded as a gas rate adjuster. NOTE 3 The action of adjusting this device is called “adjusting the gas rate”. NOTE 4 A factory sealed gas rate adjuster is considered to be non-existent. 3.1.8 setting an adjuster immobilizing a gas rate adjuster by such means as e.g. a screw,
