Horizontal flue terminal positions
Fig. 27 Horizontal flue terminal positions
Key to figure 27:
[1]
200mm below eaves and 75mm below gutters, pipe and drains.
[2]
The dimension below eaves, gutters, pipes and drains can be
reduced to 25mm, as long as the flue terminal is extended by
100mm past any overhang. The telescopic flue joint must be
sealed with suitable silicone sealant if it is external to the building.
[3]
300mm adjacent to a boundary line, unless it will cause a
nuisance. BS 5440: Part 1 recommends that care is taken when
siting terminal in relation to surfaces or boundary lines.
[4]
1,200mm separation measured between terminals facing each
other.
[5]
600mm distance to a surface or boundary line facing a terminal,
unless it will cause a nuisance. BS 5440: Part 1 recommends that
care is taken when siting terminal in relation to surfaces or
boundary lines.
[6]
The terminal must be at least 1500mm from the opening or vent
when sited below the window or 600mm when sited to either side
or above.
[7]
600mm diagonally to an opening door, air vent or opening
window.
[8]
1,200mm separation between a vertical flue measured
horizontally and a horizontal flue terminal.
Not required if the horizontal flue is 1,200mm above.
[9]
For the purpose of determining suitable flue terminal positions for
gas appliances, the boundary can be considered to extend to the
centre line of any adjacent routes or waterways e.g. paths,
streets, rights of way, canals, rivers or railways.
