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.
