GAS CATEGORIES AND
APPLIANCE CLASSIFICATION
The Seasonal Efficiency (SEDBUK) conforms to Band D. The efficiency value is used in the
UK Government Standard Assessment (SAP) for energy rating of dwellings.
The appliance meets the essential requirements for Gas Appliance
(90/396/EEC) and the Efficiency directive (92/42/EEC). It also
meets the directive 73/23/EEC relating to electrical equipment
designed for use within certain voltage limits and directive
89/336/EEC relating to electromagnetic compatibility.
The appliances were certified by the Notified Body 0087.
Any alterations to the appliance not approved by Halstead Boilers
