Seasonal Efficiency
The efficiency of this appliance has been measured as specified in BS EN 613:213 and the result is
72% Nat Gas and 73.7% LPG. 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 BELTEST. The
efficiency value may be used in the Governments Standard Assessment Procedure (SAP) for energy
rating of dwellings.
