3. APPLIANCE DATA AND EFFICIENCY
3.1 General information.
The appliance information label is at the left side of the rear case and is visible after
removing the fascia. In addition, for customers reference, there is a label giving the
appliance serial number on the outside of the fascia at the bottom right side.
3.2 Efficiency.
The efficiency of this appliance has been measured as specified in BS EN 613 and
the result is as below :
Model
Efficiency % (Gross)
473 72
The gross calorific value of the fuel has been used for this efficiency calculation. The
test data from which it has been calculated has been certified by Advantica
Certification services (0087). The efficiency value may be used in the UK
Government's Standard Assessment Procedure (SAP) for energy rating of dwellings.
The convertion of net efficiency to gross was achieved by multiplying the net
efficiency by the following conversion factor from Table E3 of SAP 2005, rounding
down to the nearest whole number.
