Important
If it is anticipated that the boiler will not be used for a long period
or the property is to be unoccupied it is recommended that the
system be drained if the electricity and gas supplies are to be
turned off. Your installer will be able to offer advice.
Where possible, draining the system should be avoided. If the system is to
be unused during winter months several precautions must be taken:
Any parts of the system that are in unheated areas of the dwelling
should be fitted with a device such as a pipe thermostat or frost
thermostat.
Power must remain supplied to the boiler and controls.
Gas must remain supplied to the boiler.
The boiler pump will operate if the system temperature drops below 7°C. If
the temperature falls to 4°C the burner will ignite and remain lit until the
temperature reaches 10°C. At this temperature the burner will extinguish
but the pump will continue to operate for 15 minutes. This feature will
protect the boiler and to some extent adjacent parts of the system but
additional devices must be incorporated to guarantee frost protection.
