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.
