7-2.2 Oil Supply Pipe
In ALL oil systems the vertical lift of the oil line should be 10mm diameter.
Horizontal runs should also be 10mm diameter, however it is good practice to use 15mm
diameter, on the horizontal sections only, of pipe runs longer than 40 metres.
IMPORTANT
The filter must be fitted outside the Building.
Tigerloops, when fitted, must be fitted outside the building.
All joints in the oil line must be oil and air tight.
No soldered joints are permissible in supply pipe.
Always flush the complete oil supply before connecting to the Burner.
When specified always fit non-return valves in the position shown on the
oil system drawings.
Walls should be sleeved where oil pipes and fire valve capillaries pass
through.
