2. APPLIANCE DATA AND EFFICIENCY
2.1 General information.
*
When converted using kit 0595211.
The appliance data label is located on a plate at the base of the fire. This can be
seen by removing the lower front casting.
2.2 Efficiency.
The efficiency of this appliance has been measured as specified in BS 7977 - 1 and
the result is as below :
Model
Efficiency % (Gross)
742 51
742 when converted to LPG.
54
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 conversion 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.
