Air gets into the central heating system when topping up with
water. Bleed the central heating system as described in par.
5.2. After bleeding, the water pressure may be below the
required level again, so the system has to be topped up with
water. Topping up and bleeding twice ought to be sufficient to
reach the correct water pressure.
Consult the installer if the central heating system has to be
topped up more than three times a year.
Enabling the boiler
Once the central heating system has been topped up, enable
the boiler again, see section 7.
