Installation regulations

Gas Safety (Installation & Use) Regulations 1998: All
gas appliances must be installed by a competent per-
son. Failure to install correctly could lead to prosecu-
tion.
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.
