Flues Regulations
Balanced Flue Siting
Note:
1. Terminal should be positioned to avoid combustion products entering the building
or accumulating in stagnant pockets around buildings.
2. The terminal must be protected by a guard if it is less than 2 metres above ground
level or in a position where any person has access.
3. A heat protection shield should be fitted if the terminal is less than 850mm from a
plastic or painted gutter or less than 450mm from painted eaves.
Saturn Heating recommends as per OFTEC recommendations that the flue should
be a minimum distance of 1 metre from openings so that it does not cause a
nuisance and permits the dispersal of combustion products.

Where the terminal is within 1 metre of any plastic material, such material should be
protected from the effects of combustion products of fuel. There are additional general
requirements in most regulations and standards that the flue must be positioned so that it
does not cause a nuisance and permits the dispersal of combustion products.
