*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 a notified body.

Note. Gas consumption is calculated using a calorific value of

38.7MJ/m3 (1038 Btu/ft3) gross or 34.9 MJ/m3 (935 Btu/ft3) nett To obtain the gas consumption at a different calorific 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)

Key to symbols

GB = United Kingdom IE = Ireland (Countries of destination) PMS = Maximum operating pressure of water

C12 C32 = A room sealed appliance designed for connection via ducts to a horizontal or vertical terminal which admits fresh air to the burner and discharges the products of combustion to the outside through orifices which, in this case, are concentric. The fan is down stream of the combustion chamber.
