*When the terminal is within 1 metre of
any plastic material this should be protected
from the effects of combustion products of

7-2.2 Terminal Guard
The temperature of the flue terminal is less than 40°C, therefore a guard is not required for
heat protection.
However the flue terminal has sharp edges and a terminal gaurd should be fitted to protect
against:-
1. head/body contact from adults and children,
2. children or adults poking their fingers in the terminal slots, or
3. damage to the terminal.
External Boilers are supplied with an integral flue which should not be removed.
