For l/s - divide the gross heat input (kW) by the grossC.V. of the gas (MJ/m 3)b. For ft3 /h - divide the gross heat input (Btu/h) by the grossC.V. of the gas (Btu/ft3 )*The value is used in the UK government's Standard Assessment Procedure (SAP) for energy rating of dwellings.The test data from which it has been calculated have been certified by BGplc 0087
