*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 Buildings Regulations clearances shown above are
minimum
allowed. Account should
also be taken of prevailing site conditions, as the above minimums may in certain circumstances
need to be increased. If in doubt contact manufacturer for advice.
