Question
Can a fixed domestic cooker hob be installed using a flexible connection?
Answer
Fixed cooker hobs may be installed using a flexible hose, providing this is approved by the appliance manufacturer. The hob should be installed in accordance with appliance manufacturer's installation instructions and BS 6172 - Specification for Installation of domestic gas cooking appliances (2nd and 3rd family gases). The flexible hose for a natural gas supply should be manufactured to BS 669 -1 Flexible hoses, end fittings and sockets for gas burning appliances. Specification for strip-wound metallic flexible hoses, covers, end fittings and sockets for domestic appliances burning 1st and 2nd family gases. Similarly, LPG flexible hoses should also be manufactured to BS 669-1(LPG versions may be identified with either a red band or a stripe). The hose itself should not be subjected to temperatures in excess of 70ºC and should be located such that it will not suffer mechanical damage such as abrasion caused by surrounding kitchen furniture, which may be moved during use, such as a cupboard drawer or door.
