3 Oil Storage & Supply System
Tiger Loop System
When The storage tank 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 Fig.
3-3. Refer to the manufacturer’s
instructions supplied with the
de-aerator. The de-aerator must be
mounted vertically, as shown in Figures
3-3 and 3-4.
To be used with a Tiger Loop system,
the burner must be fitted with an
additional flexible fuel line (a flexible fuel
line (900mm) and
3
/8” to
1
/4” BSP male
adaptor are available to purchase from
Grant Engineering (UK) Limited - Part
No. RBS36).
To prevent any possibility of fuel
fumes entering the boiler, the
de-aerator must be fitted outside the
casing.
