Installation and maintenance of domestic direct gas-fired tumble dryers of up to 6 kW heat input (2nd and 3rd family gases) – Specification Executive summary Specification for the installation and maintenance of direct gas-fired tumble dryers of up to 6 kW net heat input. Abstract This British Standard specifies the installation, including design, inspection and commissioning, of direct gas-fired tumble dryers of up to 6 kW net heat input burning 2nd and 3rd family gases for use in permanent domestic dwellings. It applies to any such tumble dryer used in conjunction with a flexible venting hose fitted to a wall or window vent terminal or, where the net heat input does not exceed 3kW, with a venting hose hung out of a window, so that combustion products and moisture are exhausted directly to the outside air. This revision to BS 7624 reflects changes to the relevant legislation and the publication of BS EN 1458-1:2000, which covers the safety of gas fired tumble dryers and replaces BS 5258-17. The previously accepted use of a tumble dryer in a flueless mode is not recognized in BS EN 1458 and, accordingly, this standard only endorses the venting options detailed in the scope. History and related standards This British Standard supersedes BS 7624:1993, which is withdrawn. This standard includes the following cross references: BS 669-1, BS 5440-2:2000, BS 5482-1, BS 6891, BS 7671. This British Standard specifies the installation (see Note 1) of direct gas-fired tumble dryers of up to 6 kW net heat input burning 2nd and 3rd family gases for use in permanent domestic dwellings (see Notes 2 and 3). It applies to any such tumble dryer used in conjunction with a flexible venting hose fitted to a wall or window vent terminal or, where the net heat input does not exceed 3kW, with a venting hose hung out of a window, so that co...
