Key to illustration 25:

1. 1,500mm measured between an opening or vented window and

vertical flue terminal.This measurement can be reduced to 1000mm

providing the flue terminal is at least 300mm above the opening.

2. Minimum clearance to an additional flue, 1,500mm between room

sealed flues or room sealed flue and open flue, 1,000mm between

open flues.

3. 600mm above a vertical structure less than 750mm from the side of

the terminal.

4. The flue must extend at least 600mm above the intersection of the

roof (flat and pitched) and be 400mm horizontally from a pitched

roof or 500mm in regions with heavy snow fall

5. The flue must not penetrate the roof in the shaded area. The flue must

be at least 2,000mm from the opening or vent when sited below the

window, 600mm when sited to either side or above.The terminal

must be at least 1,500mm room sealed, 1,000mm open flue from

the opening or vent when measured horizontally.

6. The flue must not penetrate the roof in the shaded area. The flue must

be at least 1,000mm from the opening or vent when sited below the

window, 750mm when sited to either side and 300mm above.The

terminal must be at least 1,500mm room sealed, 1,000mm open

flue from the opening or vent when measured horizontally.

7. 300mm minimum clearance measured from a non opening skylight

to a vertical flue.Vertical flue clearance,

8. 600mm minimum clearance measured from an opening or vented

skylight to a vertical flue. If the terminal is within 1,500mm of the

opening or vented skylight then it must be at least 600mm above the

opening.

9. 750mm clearance to a structure from a vertical flue.

Not required if the terminal is 600mm above the structure.

10. 750mm adjacent to a boundary line unless it will cause a nuisance.

BS 5410: Part 1 recommended that care is taken when siting

terminal in relation to boundary lines.

11. 1,200mm separation measured between a vertical flue and a

horizontal flue terminal. Not required if the horizontal flue is

1,500mm above vertical flue terminal.

12. 1,000mm (BS 5410-1) above, below and either side of an opening

door, air vent or opening window. These clearances are required by

BS 5410 Part 1 to reduce a possible pluming nuisance.If 1,000mm

cannot be achieved then the distance can be reduced to 600mm to

comply with Approved Document J of the building regulations if it

will not cause a nuisance or dispute.

13. 300mm adjacent to a boundary line unless it will cause a nuisance.

BS 5410: Part 1 recommended that care is taken when siting

terminal in relation to boundary lines.

14. 1,500mm vertically between terminals and the same wall.

15. 1,000mm (BS 5410-1) below eaves, gutters and sanitary pipe and

300mm from vertical sanitary pipes and drains.

If 1,000mm cannot be achieved then the distance below eaves,

gutters and sanitary pipe can be reduced to comply with Approved

Document J of the building regulations if it will not cause a nuisance

or dispute. 75mm if combustible material is protected or 600mm

without protection to combustible material.1)

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

reduced to 75mm, 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

17. 1,200mm between terminals facing each other.

18. 2,500mm (BS 5410-1) distance to a surface or boundary line.

If 2,500mm cannot be achieved then the distance can be reduced

to 600mm to comply with Approved Document J of the building

regulations if it will not cause a nuisance or dispute.

19. Terminals must be at least 1,800mm from an oil storage tank

unless a wall with of at least 30 minutes fire resistance and

extending 300mm wider and higher than the tank is between the

tank and the terminal. The flue air intake must be at least 900mm

away from the oil storage tank vent.

20. 1000mm diagonally to an opening door, air vent or opening

window.

21. 300mm to an internal or external corner. 300mm above a surface,

such as the ground/ floor level or roof surface.

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

reduced to 75mm, as long as the flue terminal is extended to clear

any overhang. The telescopic flue joint of the terminal must be

sealed with suitable silicon sealant if it is external to the building.

23. 1,000mm (BS 5410-1) from an opening or vented window,

300mm to a fixed unvented window. If 1,000mm cannot be

achieved then the distance from an opening or vented window can

be reduced to 600mm to comply with Approved Document J of the

building regulations if it will not cause a nuisance or dispute.

24. The flue terminal must be at least 1,500mm from the opening or

vented skylight when sited below the opening or vented skylight.

25. Proximity of flue duct outlet to boundaries, 2000mm distance to an

opening in adjacent building facing a terminal. BS 5410: Part 1

recommended that care is taken when siting terminal in relation to

boundary lines.

26. The distance between a boundary facing a flue terminal can be

measured diagonally from the point of discharge with a minimum

distance of 600mm which must be maintained. The exclusion zone

ensures compliance with Approved Document J of the building

regulations.

27. For the purpose of determining suitable flue terminal positions for

oil appliances discharging over public boundaries, 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.

NOTICE:

▶ 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 125mm x 1- Part No.: 7 716 191 179

▶ In spite of the dimensions given here, the terminal

must not be closer than 300mm to combustible

material, in the case of a thatched roof double this

dimension.

▶ Terminals must be positioned so to avoid products

of combustion accumulating in stagnant pockets

around the building or entering the building.

▶ Terminals must be at least 1.8m from an oil storage

tank unless a wall with of at least 30 minutes fire

resistance and extending 300mm wider and higher

than the tank is between the tank and the terminal.

1) A way of providing protection of combustible material would be to fit a heat

shield at least 750mm wide.

NOTICE:

▶ Installations in car ports are not recommended.

▶ Dimensions from a flue terminal to a fanned air inlet

to be determined by the ventilation equipment

manufacturer.
