FOR L/S - divide the gross heat input (kW) by the gross C.V. of the gas (MJ/m 3)b. FOR FT3/H - divide the gross heat input (Btu/h) by the gross C.V. of the gas (Btu/ft3)Table 1 - General DataTable 2 - Performance Data* The value is used in the UK Government's Standard Assessment Procedure (SAP) for energy rating ofdwellings. The test data from which it has been calculated have been certified by a notified body.GENERAL DATA
