SITE REQUIREMENTS (continued)
Any type of fire surround used with this appliance must be adequately sealed to the wall and floor.
A combustible shelf may be fixed to the wall above the fire, providing that it complies with the dimensions given
below.
A non-combustible shelf may be fitted to within 10mm of the top edge of the fireframe.
Combustible materials, such as wood, may be fitted to within 100mm (4in) of either side of the fireplace
opening, providing the forward projection does not exceed 100mm (4in).
Any combustible side walls must be at least 500mm to the side of the radiant heat source.
As with all heating appliances, any decorations, soft furnishings, and wall coverings (i.e. flock, blown vinyl and
embossed paper) positioned too close to the appliance may discolour or scorch.
DEBRIS COLLECTION SPACE
The mounting depth of this appliance is 125mm.
In accordance with BS 5871 part 2, minimum debris collection volumes are required behind the installed
appliance. These are shown in the table below and as dimension X on the fireplace diagram shown previously.

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 correct operation of the flue. If the appliance does not spill with the windows open, but
spillage is detected with the windows closed, this demonstrates a lack of natural ventilation. If spillage is still
detected with the windows open, the flue is 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 fitted under,
or within immediate vicinity of, the appliance must not be used, as it may adversly effect performance of the
O.D.S system.
Spillage detected during commissioning is almost always a result of poor flue performance that 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.
