Max. oil level is 4 metres above burner. Where this height is unavoidably
exceeded, a pressure reducing valve should be fitted to the supply line.
OIL STORAGE TANK SITING
Consult OFTEC Manuals
It is unlikely that a fire will start at an oil tank. However,
the stored fuel must be protected from a fire or heat
source that originates nearby.For this reason oil tanks of
up to 3500 litres should be separated from openings,
other than airbricks, in the building by a minimum of
1.8m and a non-fire rated boundary by a minimum of
760mm.Where this cannot be achieved, a 30 minute fire
rated barrier should be constructed between the
hazard and the tank, which extends a minimum of
300mm higher and 300mm past each end of the tank.
Note that a minimum separation distance should be
maintained between a flue exit and fire barrier (see
page 15 (flue clearances).
Steel tanks must be mounted on brick or block piers
with a waterproof membrane between the piers and
tank.
Oil storage tanks should not be sited within 1.8m
of boiler flue outlets.
Do not allow household waste or hot ashes container
in vicinity of oil storage tank or boiler flue outlet.
FLEXIBLE OIL PIPE(S)
A flexible burner oil hose is supplied with the boiler
which must be wholly contained with in the appliance
case.
The flexible oil pipe supplied with the boiler is suitable
for Kerosene only. The oil pipe must be upgraded to a
bio-compatible Riello flexible oil pipe where a bio-fuel
mixture is used.
Please note: A filter must not be fitted inside the
boiler and all joints in the oil line must be oil
tight. Soldered joints are not permissible. Before
connecting to the boiler, always flush the complete
oil supply line and ensure that oil supply is
completely clean and free of any dirt or foreign
matter.
SINGLE PIPE SYSTEM
Where installation is such that the bottom of the tank is
located above the oil burner, a single pipe system may
be used. The oil burner should then be set for single
pipe operation (see also manufacturer's oil burner
manual).
