Notes:
1. In addition, the terminal should not be nearer than 150mm to the framework of an opening into the building, i.e. a window surround or door surround.
2. This clearance may be reduced to 25mm without effecting the performance of the boiler. However, to ensure the condensate plume does not affect adjacent
surfaces a clearance of 300mm is preferable.
3. These clearances may be reduced to 25mm without effecting the performance of the boiler. However, to ensure the condensate plume does not affect adjacent
surfaces the terminal can be extended beyond gutters, pipes, eaves, balconies etc. by up to 500mm. If the flue is extended more than 500mm outside, it should
be boxed and insulated.
4. To reduce the possibility of nuisance to neighbouring buildings etc. it is recommended the terminal should not be less than 2500mm from car parking spaces,
building boundary walls, fences etc.
5. A terminal must not be sited under a car port roof.
6. In certain weather conditions the terminal will emit a plume of steam. If possible avoid positioning the terminal where this may cause a nuisance, i.e. positions A,
D, G, H, J or M.
7. The flue terminal must be exposed to the external air and the position must allow the free passage of air across it at all times.
8. A terminal must not be sited below 2m where people have access to, such as public footpaths, access routes, patios etc. However, If the terminal is fitted less
than 2m above a surface where there is no public access, the terminal must be protected by a terminal guard.
