  • Page 4 The boiler will repeat the ignition sequence. INTRODUCTION The Keston 30C is a wall mounted, room sealed, condensing combination boiler, featuring full sequence automatic spark ignition and fan assisted combustion. Due to the high efficiency of the boiler, condensate is produced from the flue gases and this is drained to a suitable disposal point through a plastic waste pipe at the base of the boiler.

  • Page 9: To Shut Down The Boiler

    C (147 The Keston 30C is a high efficiency combination boiler which is most efficient when operating in condensing mode. The boiler will operate in this mode if the CH temperature control (C) is set to the ‘e’ position (economy mode) or below. This control should be set to a maximum for very cold periods.

  • Page 10: Loss Of System Water Pressure

    LOSS OF SYSTEM WATER PRESSURE The gauge (G) indicates the central heating system pressure. If the pressure is seen to fall below the original installation pressure of 1-2 bar over a period of time then a water leak may be indicated. In this event conduct the re-pressurising procedure as shown below.

  • Page 11: Condensate Drain

    CONDENSATE DRAIN The condensate drain (H) must not be modified or blocked. Blockage of the condensate drain, caused by debris or freezing, can cause automatic shutdown of the boiler. If freezing is suspected and the pipe run is accessible an attempt may be made to free the obstruction by pouring hot water over the exposed pipe and clearing any blockage from the end of the pipe.
