If the boiler is to be out of use for any long periods
during severe weather

boiler, be drained to avoid the risk of freezing.
If in doubt, consult your servicing company.
The ECOSY boilers have a built in frost protection
device that protects the boiler from freezing. If the
boiler is to be left and there is a risk of frost, ensure
that the gas and electrical supplies are left
