Note

•

All measurements are the minimum clearances required.

•

Terminals must be positioned so to avoid combustion products

entering the building.

•

Support the flue at approximately one metre intervals and at a

change of direction, use suitable brackets and fittings

(flue bracket part numbers:

100mm – 7 716 191 092, 125mm – 7 716 191 174).

5. The dimension below eaves, gutters, pipes and drains can be

reduced to 25mm, as long as the flue terminal is extended to

clear any overhang. Any external flue joints must be sealed

with a suitable silicon sealant.

6. 500mm clearance to any vertical structure on a roof, 600mm to

room sealed flue or 1,500mm to an open flue.

7. 1,500mm between a vertical flue terminal and a window or

dormer window.

8. 400mm from a pitched roof or in regions with heavy snow fall

500mm.

9. The flue cannot be lower than 1,000mm from the top of a light

well due to the build up of combustion products.

10. 2,000mm below a Velux window, 600mm above or to either

side of the Velux window.

11. 200mm below eaves and 75 mm below gutters, pipes

and drains.

12. 1,200mm between terminals facing each other.

13. 300mm to an internal or external corner.

Installations in car ports are not recommended.

14. The dimension below eaves, balconies and car ports can be

reduced to 25mm, as long as the flue terminal is extended to

clear any overhang. Any external flue joints must be sealed

with suitable silicon sealant.

15. 300mm above, below and either side of an opening door,

air vent or opening window.

Key to illustration

1. Flue clearance must be at least 300mm from the ground.

Terminal guards must be fitted if the flue is less than 2 metres

from the ground or if a person could come into contact with

the flue terminal.

2. 600mm distance to a boundary, unless it will cause a nuisance.

BS 5440: Part 1 recommends that care is taken when siting

terminals in relation to boundaries.

3. 600mm minimum clearance from a skylight to a vertical flue.

4. Vertical flue clearance, 500mm to non-combustible building

material, and 1,500mm clearance to combustible building

material.
