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. Any ventilation fitted must
comply with BS 5871 part 2 and BS 5440 part 2.
Spillage detected during commissioning is almost always a result of poor flue performance, which
cannot be corrected 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 FLUE BOXES
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 not
obscure the flue outlet from the flue box. A smooth path into the flue must exist.
Constructional 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 clear-
ances to combustible materials (e.g. false chimney breast construction) must be maintained.
The manufacturers’ instructions for the fitting of the prefabricated flue box shall be com-
plied with at all times.
Some flue boxes may require minor adaption when fitting the fire using the cable fixing kit.
The firebox, base of the flue box, and the hearth may be drilled to allow plugs and screws to
secure installation.
It is important that the sealing requirements of the appliance are met at all times and that the flue
box is well sealed to any back or infill panel.
Note: The DEPTH dimensions shown are inclusive of any back or infill panels.
