Digital Display/ System Pressurisation
The digital display normally shows the operating temperature
of the unit when there is a central heating demand and gives a
pressure reading when there is no demand or when the appliance
is in the domestic hot water mode.
If the digital display shows pressure less than 0.7bar, re-
pressurise the system to 1bar by gently opening the built in
filling tap underneath the boiler, see diagram 2. A tap extension
tool is provided to facilitate this. Ensure the tap is closed. If the
system repeatedly loses pressure, YOU MUST CONTACT
YOUR INSTALLER OR GLOW-WORM'S OWN SERVICE
ORGANISATION USING THE TELEPHONE NUMBER ON
THE INSIDE FRONT COVER OF THIS BOOKLET.
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 (see 'Protection
Against Freezing') 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.
To turn off the boiler for servicing, isolate it from the electrical
supply. To turn it on again follow the instructions given in
'Operation of the Boiler'.
