Oil filters
Oil filters must always be incorporated in the oil supply
line, one on the outlet from the oil tank to filter deposits
from within the tank or fuel and one near the appliance to
filter deposits from within the fuel line itself. They are
supplied and fitted by the installing engineer and are not
part of the boiler's components. They should be able to be
serviced without the need for draining down the fuel supply
line. There must be sufficient clearance below the filter to
enable servicing operations to be carried out easily. Filters
must comply to OFTEC standard OFS E104.

Fire valves
A fire valve is an essential part of the oil supply system. It is
supplied and fitted by the installing engineer and is not part
of the boiler's components. Its purpose is to cut off the
flow of oil outside the building in the event of fire within
the boiler area. The valve should be located at the point of
entry into the building of the fuel line. It must be activated
by a remote sensor located over the burner. A clip is
provided within the appliance for the sensor. Fire valves
must comply with OFTEC standard OFS E101.
