12、 has been prepared under the direction of the Engineering Sector Board and is a revision of BS 5871-3:1991, which is withdrawn. A period of three months has been allowed for users of the old standard to convert to the new standard. This revision reflects experience gained in the use of the 1991 edit
13、ion for the installation of decorative fuel effect gas appliances1) and also provides additional guidance on the use of fanned draught flueing and flue sizing. BS 5871 continues to cover the different types of fuel effect appliances in a single series of British Standards, as follows: Part 1: Gas fi
14、res, convector heaters, fire/back boilers and heating stoves (1st, 2nd and 3rd family gases); Part 2: Inset live fuel effect gas fires of heat input not exceeding 15 kW and fire/back boilers (2nd and 3rd family gases); Part 3: Decorative fuel effect gas appliances of heat input not exceeding 20 kW (
15、2nd and 3rd family gases). To identify which part of BS 5871 to use when fitting an appliance which simulates a solid fuel fire, reference should be made to Figure 1 which serves to illustrate appliance types and link them to the appropriate part of BS 5871. It should be noted that the only fuel eff
16、ect appliances covered by this part of BS 5871 are those detailed in b) of the commentary and recommendations on clause 5 of this standard. The manufacturers instructions supplied with fanned draught appliances in which the fan is either integral with the appliance or with the flue system will make
17、reference to the appropriate part of BS 5871. It should be noted that the only appliances covered by this part of BS 5871 are those that are “CE” marked. However, BS 5871-3 may also be referred to for the installation of used appliances, where appropriate, providing the manufacturers instructions ar
18、e available. In such circumstances, the installer should satisfy himself that the appliance is safe in construction and condition, and can be used without constituting a danger. Attention is drawn to clause 5 concerning this particular aspect. Arising from European Standards harmonization, some Brit
19、ish Standards appliance specifications are now being replaced by European Standards. One consequence of this process is that the reference clearance flue flow test, currently included in some of the British Standards covering the safety of appliances dealt with by BS 5871, will not be given in Europ
20、ean appliance standards. This test has hitherto been used to determine the flue flow, under laboratory conditions, that an appliance will just clear its combustion products. The test has been used as a key factor in determining whether or not certain appliances of 7 kW2) heat input or less require p
21、urpose provided ventilation for their installation. Although BS 5871 is an appliance installation standard, the drafting committee has decided to include the clearance flue test as an informative annex. It is hoped that this arrangement will provide Notified Test Houses under the Gas Appliance Direc
22、tive with a continuing means to evaluate appliances for installation within the UK which claim that no purpose provided ventilation is necessary for their installation. 1)Sometimes referred to as a decorative gas fire or DGF. 2)Due to tolerances, this applies to a heat input of 7 kW on both net and
23、gross calorific value. See clause 1, Scope, note 2.

24、 which differs in points of detail from this standard. This reference to manufacturers instructions is allowed only where it will result in at least an equivalent level of safety. In such circumstances, it is important that the manufacturers instructions are followed. NOTEIn the preparation of this
