NOTES:
1 All distances are measured to the nearest part of the terminal.
2 Prohibited area below electricity meter or fuse box extends to ground level.
3 Where the flue terminal of a balanced flue appliance, a fan-assisted flue appliance, a room sealed appliance
or the flue terminal of an appliance designed for outdoor installation is to be installed under a covered area -
(a) the covered area is to be open on at least two sides; and
(b) the terminal is to be located to ensure a free flow of air across it is achieved.
4 See Appendix J, Figures J2(a) and J3(a), for clearances required from a flue terminal to an LP Gas cylinder.
A flue terminal is considred to be a source of ignition.
5 For appliances not addressed above, acceptance should be obtained from the technical regulator.
