10 Appliance safety devices
10.1 Boiler Shutdown
The boiler software is designed to
recognise the potential for an overheat
lockout and will shutdown before this
happens.
• To restart the boiler, press the reset
button, see chapter «Quick reference
guide».
If the boiler fails to resume normal
operation and all external controls are
calling for heat, then call your Installation/
Servicing company or Glow-worm service.
10.2 Protecting against frost
10.2.1 Appliance Protecion
In case of the risk of frost:
• Make sure that the electrical and gas
supply to the appliance is turned on.
• The frost-protection system starts the
appliance’s pump when the temperature
in the heating circuit goes below 12°C.
The pump stops when the temperature of
the water in the heating circuit reaches
15°C. If the temperature in the heating
circuit goes below 7°C, the burner is lit
until the temperature reaches 35°C.
If the boiler is in «Domestic Hot Water»
mode only, the frost-protection system is
also active.
10.2.2 System Protection
The boiler alone cannot ensure that the
installation is protected against frost.
NOTE: Any other exposed areas of the
system should be protected by a separate
frost thermostat.
In case of prolonged absence, where power
to the dwelling and the boiler is switched
o, contact your Installation/Servicing
company or Glow-worm Service to have the
installation drained or to have the heating
circuit protected by adding an anti-freeze
specially designed for heating systems.
b CAUTION:
Yourdomesticwatercircuit(hotand
cold)isnotprotectedbytheboiler.
10.3 Condensate Drain Blockage
As a safety feature the boiler will stop
working if the condensate drain becomes
blocked. During freezing conditions this
may be due to the forming of ice in the
condense drain external to the house or in
an unheated area such as a cellar or loft.
• Release an ice blockage by the use of
warm cloths on the pipe.
b Warningnote:
Donotuseboilingwater.
The boiler should then restart.
• Contact your Installation/Servicing
company or Glow-worm service if the
fault persists.
10.4 Safety Discharge Valve
The safety discharge valve and discharge
pipe is tted to the boiler.
• If there is any discharge from the pipe,
switch o the boiler electrical supply,
then call your Installation/Servicing
company or Glow-worm service.

12 Tips for saving energy
Your installer will be able to give energy
saving advice about your system and its
controls.
For energy saving advice you can contact
the Energy Savings Trust for advice or

oer simple eective advice about saving
energy.
Regular servicing of your boiler will help
maintain its eciency - servicing once a
year is recommended.
Turn your thermostat down. Reducing your
room temperature by 1°C could cut your
heating bills by up to 10 percent. Set your
heating and hot water at the time controller
to come on only when required rather than
all the time.
