Notes:
1.
Prohibited area below electricity meter or fuse box extends to ground level.
2.
Where dimensions c, j or k cannot be achieved, an equivalent horizontal distance measured diagonally from the
nearest discharge point of the terminal to the opening may be deemed by the Technical Regulator to comply.
3.
Refer to AS/NZS 5601.1 clause 6.9.4 for restrictions on a flue terminal installed under a covered area.
4.
Refer to AS/NZS 5601.1 figure J3 for clearances required from a flue terminal to an LP gas cylinder. A flue
terminal is considered a source of ignition.
5.
For appliances not addressed above, acceptance should be obtained from the Technical Regulator.
