4.3 Function
The burner pump draws the liquid fuel from the tank via the check valve
installed in the product. The fuel not burnt by the burner nozzle is returned to
the vent via the return line and then resupplied to the burner via the flow line.
Only the amount of fuel actually burnt is taken from the tank and added to the
de-aerated fuel.
The upper float chamber keeps foam from escaping through the vent open-
ing.
