5.9 connecting a condensate pump
If a suitable drain for condensate disposal is located too high to be able to discharge the condense
water from the boiler, a condense pump must be installed within the base of the boiler.
This condensate pump has a built-in safety device. If the pump outlet is blocked, the water level in the
pump reservoir will rise to just below the rim – if the level rises any further, the power to the boiler will be
switched off.
At the right hand side, in the area of the boiler base, there is a socket – if no condensate pump is used,
there will be a plug with a control link in place. The condensate pump (KHP1) must be wired into this plug
once the link wire has been removed.
