NOTES:
1
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.
2 See Clause 6.9.4 for restrictions on a flue terminal under a covered area.
3 See Figure J3 for clearances required from a flue terminal to an LP Gas cylinder. A
flue terminal is considered to be a source of ignition.
4 For minimum clearances not addressed above acceptance should be obtained from the
Technical Regulator.
5 Minimum clearances d and e also apply to any combustion air intake openings of appliances.
