Oil Storage &
Supply System
Two Pipe System - (See Figure 3-1)
With the storage tank outlet below the
burner, a two pipe system should be
used. The pipe runs should be as shown
in Figure 3-1. The return pipe should be at
the same level in the tank as the supply
pipe, both being 75 to 100mm above the
base of the tank. The pipe ends should
be a sufficient distance apart so as to
prevent any sediment disturbed by the
r
eturn entering the supply pipe.
Avoid the bottom of the tank being
more than 3m below the burner.
A non-return valve should be fitted in
the supply pipe together with the filter
and fire valve. A non-return valve should
be fitted in the return pipe if the top of
the tank is above the burner.
The pump vacuum should not exceed
0.4 bar.
Beyond this limit gas is released from
the oil.
For guidance on installation of top
outlet fuel tanks and suction oil supply
sizing, see OFTEC Technical Information
Book 3. Available from OFTEC.

Tiger Loop System -
(See Figures 3-2 and 3-3)
When the storage tank outlet is below
the burner, an alternative to a two pipe
system can be achieved using a
'Tiger Loop' type oil de-aerator.
This effectively removes the air from
the oil supply on a single pipe lift.
The de-aerator is connected close to the
boiler as a two pipe system (omitting the
non-return valve) as shown in Figure 3-2.
Refer to the manufacturers instructions
supplied with the de-aerator.
The de-aerator must be mounted
vertically, Figure 3-2.
To prevent any possibility of fuel
fumes entering the building, the
de-aerator must be fitted outside in
accordance with BS 5410:1:1997.
