Gas consumption is calculated using acalorific value of 38.7 MJ/m 3 (1038 Btu/ft3) grossor 34.9 MJ/m 3 (935 Btu/ft3 ) nettTo obtain the gas consumption at a differentcalorific value:a. For l/s - divide the gross heat input(kW) by the gross C.V. of the gas (MJ/m3)b. For ft3 /h - divide the gross heat input (Btu/h)by the gross C.V. of the gas (Btu/ft3)c. For m3 /h - multiply l/s by 3.6.Key to symbolsgB = United Kingdom IE = Ireland (Countries of destination)pMs = Maximum operating pressure of waterC 13 C 33 C 53 = A room sealed appliance designed for connection via ducts to ahorizontal or vertical terminal, which admits fresh air to the burnerand discharges the products of combustion to the outside throughorifices which, in this case, are concentric. The fan is up stream ofthe combustion chamber.I2h = An appliance designed for use on 2nd Family gas, Group H only.* The value is used in the UK Government’s Standard Assessment Procedure (SAP) for energy rating of dwellings.
