Gas Safety (Installation & Use) Regulations: All gas
appliances must be installed by a competent person.
Failure to install correctly could lead to prosecution.
The manufacturers notes must not be taken, in any way,

bye-laws of the local ater Company, Health and
Safety Document 635 (Electricity at ork Regulations
1989) and any other local requirements.
Product Liability regulations indicate that, in certain cir-
cumstances, the installer can be held responsible, not

ing from the use of faulty materials. e advise the
installer to avoid any risk by using only quality approved
branded fittings.
The relevant British Standards should be followed i.e.
• BS 6798: Specification for the installation of gas
fired hot water boilers of rated input not exceeding
60k
• BS 5449: Central Heating for Domestic Premises
• BS 5546: Installation of gas hot water supplies for
domestic purposes
• BS 5440:1: Flues and ventilation for gas appliances
of rated input not exceeding 70 k (net): Flues
• BS 5440:2: Flues and ventilation for gas appliances
of rated input not exceeding 70 k (net): Air
Supply
• BS 6891: Installation of low pressure gas pipework
installations up to 28mm (R1).
• BS 6700: Domestic water supply (when relevant)
• BS 7671: Requirements for Electrical Installation.
These instructions must be followed.
