NOTES: 1. All distances are measured vertically or horizontally along the wall to a point in line with the nearest part of the terminal.

2.Prohibited area below electricity meter or fuse box extends to ground level.

3.See clause 5.13.6.6 for restrictions on a flue terminal under a roofed area.

4.See Appendix J, Figure J1(a) and J2(a) for clearances required from a flue

terminal to a LP Gas cylinder. A flue terminal is considered to be a source of ignition.
