9.4 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 "How to use your
appliance ► Overview".
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.
