Fig. 30 Horizontal flue terminal positions
Key to figure 30:
[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] 600m 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.

when sited below the window or 600mm when sited to either side
or above.

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.
[10] 300mm to an internal or external corner. 300mm above a
surface, such as the ground/ floor level or roof surface.
* If the terminal section is less than 150mm and has two screws
securing it to the elbow, the terminal section will not require a
supporting bracket.
