WD209/1/2000 Chapter 2 - Boiler Connections The Keston Celsius 25 & 25P2.10 COMPARTMENT INSTALLATIONDue consideration should be given to BS5440 pt 1 with regard to compartment ventilationrequirements. High and low level ventilation is required for cooling purposes as follows:Position of air vent Air from room Air direct from OutsideHigh 306 cm 2 153cm 2Low 306 cm 2 153cm 2Both vents must communicate to the same room or be on the same wall to outside.2.11 CONDENSATE DRAINAGEBeing a condensing boiler, the Celsius 25 is fitted with a condensate trap at the base ofthe heat exchanger and flue assembly, with facility to connect to a drain point underneaththe appliance.Use only plastic piping and do not reduce below 15 mm internal diameter within thedwelling. Condensate should preferably be drained into the sanitary waste system or,alternatively, the rainwater system of the property in most cases. Ensure in all cases thatthe disposal of the condensate is in accordance with any local regulations in force.Termination of the pipe must be either at a branch or stack internal to the house, orexternally at an open gully. Alternatively, discharge into a purpose made condensatesoakaway can be considered. Existing or purpose built drains must use suitable corrosionresistant material as condensate is mildly acidic.The connection to the condensate drain of the boiler, and the condensate drain pipeworkitself, should be properly sealed to ensure there is no possibility of leakage into thedwelling.A minimum slope downwards towards the drain of 1 in 20 is essential. Freezing of thetermination and pipework must be prevented. Any drainage pipes outside the propertymust be at least 32 mm inside diameter.Installation & Servicing Instructions Page : 14
