Boiler Safety Devices
Overheat Reset
The boiler is designed to lockout when an overheat happens. When
the boiler is locked out, the indicator lights steadly. To restart the
boiler, turn the left knob on position, wait one minute to cool down
the boiler, and then turn it on previous operating position (see
diagram 2).
If the boiler fails to resume normal operation and all external controls
are calling for heat, or if the boiler locks out again, then call your
Installation/Servicing company or Glow-worm service.
Frost Protection
With the gas and electric supplies ON and irrespective of any setting
of boiler’s control or room thermostat, the integral frost protection
device will ignite the burner and operate the pump when the tempera-
ture of the boiler water falls below 5°C.
The burner will switch off when the temperature reaches 30°C.
NOTE: Any other exposed areas of the system should be protected
by a separate frost thermostat.
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. Release
an ice blockage by the use of warm cloths on the pipe. The boiler
should then restart. Contact your Installation/Servicing company or
Glow-worm service if the fault persists.

Safety Discharge Valve
A safety discharge valve and discharge pipe is fitted to the boiler. This
valve MUST not be touched. If there is any discharge from the pipe,
switch off the boiler electrical supply, then call your Installation/
Servicing company or Glow-worm service.
