34、of gas families that it is designed to burn. The gas families are identified by subscripts T, N and L for 1st, 2nd and 3rd gas families respectively. Subscripts P and B denote to propane and butane respectively. For the purposes of this Part of BS 5258, the following categories of appliance are perm
35、itted: Categories IN, IL, IL/B, IL/P Categories IINL, IINL/B, IINL/P Within a given category the changes that are allowed in adapting an appliance from operation on one gas or gas family to operation on another are limited as follows. a) Change of gas family. 1) Adjustment of governor setting or exc
36、hange of governor springs or immobilization of the governor (when fitted). 2) Exchange of injectors or non-aerated burner assemblies. 3) Adjustment of aeration. 4) Exchange or adjustment of auxiliary components (e.g. pilots, igniters, restrictors). b) Change of gases within 3rd family. 1) Adjustment
37、 of aeration. 3.2 Classification by flue type Appliances are also classified according to the flue system for which they are designed and the source of the combustion air. This Part of BS 5258 covers type B, i.e. open-flued appliances only. NOTEThe definition of this type of appliance is given in BS
38、 1179-6. 4 General requirements The appliance shall comply with this Part of BS 5258 when tested using the specified test gases of the appropriate gas family. NOTE 1Full details of the test gases are given in BS 4947. NOTE 2Appliances designed to burn 3rd family gases may be designed for use with ei
39、ther commercial butane or commercial propane, or both. When submitted for type testing an appliance shall be supplied with all decorative trims and fire fronts. 5 General conditions of test 5.1 Test room The room shall be adequately ventilated, but free from draughts likely to affect the performance
