To obtain the gas consumption at a different calorificvalue:-a. For l/s - divide the gross heat input (kW) by the grossC.V. of the gas (MJ/m3)b. For ft3 /h - divide the gross heat input (Btu/h) by thegross C.V. of the gas (Btu/ft 3)c. The appliance is preset at the factory to the highestnominal rating.Key to symbolsGB = United Kingdom IE = Ireland(Countries of destination)PMS = Maximum operating pressure of waterC11 = A room sealed appliance designed for connection viaducts to a horizontal terminal, which admits fresh airto the burner and discharges the products ofcombustion to the outside without a fan in thecombustion products circuit.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 ofdwellings. The test data from which it has been calculated have been certified by Advantica 0087CAUTION. To avoid the possibility of injury during the installation, servicing or cleaning of thisappliance, care should be taken when handling edges of sheet steel components.Boiler Size RS485 RS4100 RS4125Gas Supply Connection in.
