3.4.5 Tiger Loop system - (See Figs. 4 and 5)
1 When The storage tank is below the burner, an
alternative to a two pipe system can be achieved using
the Tiger Loop oil deaerator. This effectively removes
the air from the oil supply on a single pipe lift.
2 The Tiger Loop is connected close to the boiler as
a two pipe system (omitting the non-return valve)
as shown in Fig. 4. Refer to the manufacturers
instructions supplied with the Tiger Loop.
The Tiger Loop must be mounted vertically.
Note: To prevent any possibility of fuel fumes
entering the building, the Tiger Loop must be
fitted outside.
