2. For longer periods:
Set the boiler HEATING switch (G) and WATER switch (J)
to OFF.
Turn the gas control knob (F) CLOCKWISE until
resistance is felt, and then release it in order to extinguish
the pilot burner.
Switch the electricity supply to OFF.
WARNING.
If no frost protection is provided and frost is likely during a
short absence from home, leave the heating controls (if fitted) at
a reduced temperature setting.
For longer periods the entire system should be drained,
including the domestic water supply.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) only.
The mains supply should be left switched ON with the boiler
HEATING and WATER switches remaining in the OFF positions.
