*Where the terminal is within 1m of any plastic material, such material should be shielded from the effects of
the combustion products of the flues
NOTE:- Whilst the dimensions in BS 5410 are shown in the table, it is stressed that possible variances
in local site conditions may not always be obvious and that if in any doubt the dimensions in brackets
should be observed.

5:5 TERMINAL GUARDS
When the terminal is positioned where there is the possibility of accidental contact by persons, or of damage
to the terminal, an approved guard is necessary (Boulter Code FL26160).
Generally, exhaust 2 metres above ground level alleviates the necessity for a guard.
A
suitable guard is available from BOULTER BUDERUS as shown below.
