System Pressurisation
(F24e & F28e ONLY) If the digital display shows pressure less
than 0.7bar, re-pressurise the system to 1bar by gently opening
the built in filling taps underneath the boiler, see diagram 2. Tap
extension tools are provided to facilitate this.
Using the tap extensions connected to tap (a) and tap (b) open
tap (b) and then slowly open tap (a). Re-pressurise the system
to a pressure of 1.0 bar indicated on the digital display. When
the system is pressurised you must close tap (b) and then tap
(a).
If the system repeatedly loses pressure, YOU MUST CONTACT

To Turn the Boiler Off
There is a mains reset switch on the right hand side of the
controls fascia, which will isolate the boiler. However, it is
preferable to leave the electrical supply on whenever possible
to permit operation of the built-in frost protection and daily pump
and valve exercise.
To turn off the central heating use the room thermostat or
programmer.
To turn off the domestic hot water turn the hot water temperature
control knob to the minimum setting.
For holiday mode turn both of the temperature knobs to the
minimum setting.
