Tiger Loop System -
(See Figures 3-3 and 3-4)
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 manufacturers
instructions supplied with the de-
aerator. The de-aerator must be
mounted vertically, as shown in Figures
3-3 and 3-4.
To prevent any possibility of fuel
fumes entering the building, the
de-aerator must be fitted outside in
accordance with BS 5410:1:1997.
