4.3 - FLUE REGULATIONS - REGULATIONS & GUIDELINES
BALANCED FLUE SITING
Notes:
1.
The 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 to it (i.e. a balcony).
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.
4.
Prevailing wind should be taken into account when siting a flue.
*
FIREBIRD 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
(SEE PAGE 10).
ALWAYS CHECK FOR ANY BUILDING REGULATIONS AMENDMENTS WHICH MAY

Book 3 2010
*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.
NOTE:
The Building Regulations clearances shown above are the minimum allowed. To take account of
prevailing site conditions, it is advisable wherever necessary, to follow the manufacturer’s preferred
recommendation. If in doubt contact the manufacturer for advice.
