3.6. Ventilation
For models with heat inputs not exceeding 6.9kW additional ventilation is not normally
required in the room that the fire is fitted. However, if spillage is detected during spillage test
additional ventilation may be required. In GB reference should be made to BS 5871:Part 3,
and in IE, reference should be made to the current edition of I.S.813 which makes clear the
conditions that must be met to demonstrate that sufficient ventilation is available.
Models with heat inputs in excess of 6.9kW require a minimum of 100cm
2
ventilation in the
room where the fire is installed when installed in Great Britain (GB) and in IE, reference should
be made to the current edition of I.S.813 which makes clear the conditions that must be met to
demonstrate that sufficient ventilation is available.
If provided, any purpose provided ventilation must be checked periodically to ensure it is free
from obstructions.
When fitting the fire in Northern Ireland (NI), purpose provided ventilation must be provided in
accordance with the rules in force.
In other EC countries equivalent rules in force must be used.
