[*] Minimum distance of the flue terminal from above ground is
2100mm where directed to a public footpath, private access
route or a frequently used area and 2500mm from a car
parking area.
[**] Recommended minimum distance of the flue terminal to a
facing wall, fence, building or property boundary is
2500mm.
1. Terminals should be positioned so as to avoid products of
combustion accumulating in stagnant pockets around the building or
entering into buildings.
2. Vertical structure in N, O and P includes tank or lift rooms, parapets,
dormers etc.
3. Terminating positions should be at least 1.8m from an oil storage
tank unless a wall with at least 30 minutes fire resistance and
extending 300mm higher and wider than the tank is provided
between the tank and the terminating position.

• Where a flue is terminated less than 600mm away from a projection
above it and the projection consists of plastics or has a combustible
or painted surface, then a heat shield of at least 750mm wide should
be fitted.
• If the lowest part of the terminal is less than 2m above the ground,
balcony, flat roof or other place to which any person has access, the
terminal should be protected by a guard.
• Notwithstanding the dimensions given above, a terminal should not
be sited closer than 300mm to combustible material. In the case of a
thatched roof, double this separation distance should be provided. It
is also advisable to treat the thatch with a fire retardant material and
close wire in the vicinity of the flue.
• It is essential that a flue or chimney does not pass through the roof
within the shaded area delineated by dimensions Q and R.
• Where protection is provided for plastic components, such as
guttering, it is essential that this is to the standard specified by the
manufacturer of the plastic components.
