Installation regulations
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,
as overriding statutory obligations.
The appliance must be installed in accordance with the
current IEE Wiring Regulations, local Building Regula-
tions, Building Standards (Scotland) (Consolidation),
bye-laws of the local Water Company, Health and
Safety Document 635 (Electricity at Work Regulations
1989) and any other local requirements.
Product Liability regulations indicate that, in certain cir-
cumstances, the installer can be held responsible, not
only for mistakes on his part but also for damage result-
ing from the use of faulty materials. We 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
60kW
• 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 kW (net): Flues
• BS 5440:2: Flues and ventilation for gas appliances
of rated input not exceeding 70 kW (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.
