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 «Appliance use ▸

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.

10.2 Protecting against frost

Appliance Protecion

In case of the risk of frost:

• Make sure that the electrical and gas

supply to the appliance is turned on.

• For an absence of several days, select

the «frost protection» mode. In this

mode, only the water pressure in the

heating circuit is visible.

or

• Set the «holiday» mode in the external

control.

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.

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

off, 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.

• 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.

10.4 Safety Discharge Valve

The safety discharge valve and discharge

pipe is fitted to the boiler.

• If there is any discharge from the pipe,

switch off the boiler electrical supply,

then call your Installation/Servicing

company or Glow-worm service.
