Tiger Loop System - Grant Combi 70 V3 User's Installation Manual

5.3.5 Tiger Loop system - (See Figs. 7 and 8)
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. 7. 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.

must be fitted with an additional flexible fuel line
(a flexible fuel line (600 mm) and
male adaptor are available to purchase from Grant
