VENTILATION
No purpose provided ventilation is normally required for this appliance. The requirements of other appliances
operating in the same room or space must be taken into consideration when assessing ventilation.
If spillage is detected when commissioning the appliance then amongst other problems there may be insufficient
natural ventilation for the correct operation of the flue. This is potentially a greater problem should the property
be of modern nature. If the appliance does not spill with windows open but does with windows closed, this
proves that lack of ventilation is the problem, if not, it will be the flue at fault. Installation of an air brick is the best
solution to lack of ventilation. Any ventilation fitted must comply with BS 5871 part 2 and BS 5440 part 2.
Ventilation located underneath or within the immediate vicinity of the appliance MUST NOT be used as it may
adversely affect the performance of the O.D.S. system.
Spillage detected during commissioning is almost always a result of poor flue performance, which cannot be cor-
rected by any amount of ventilation.
For Republic of Ireland ventilation may be required, see IS 813, ICP3, IS 327, and any other rules in force.
PREFABRICATED FFLUE BBOXES
This appliance can be fitted into a number of proprietory flue boxes, provided that the minimum dimensions
given in the diagram below are complied with. The flue outlet of the fire must nnot obscure the flue outlet from
the flue box. A smooth path into the flue must exist.
Consstrucctional N
Note: The frame of the fire, any back panel or other infill panel, and the flue box must be sealed
together so that there is no possibility of leakage between them. Adequate clearances to combustible materials
(e.g. false chimney breast construction) must be maintained.
