7-3.3 Single Pipe System - Deaerator (Tigerloop)
When the Burner is over 1 metre above the tank the installation normally requires a two
pipe system, however, a ‘Tigerloop’ deaerator can be used which removes air from a
single pipe lift oil feed. Higher lift heights can be achieved than are possible with
conventional two pipe systems.
IMPORTANT
The Tigerloop must be fitted upright close to the Boiler and must be
OUTSIDE the property.
