Where no specific instructions are given, reference should be made to the relevant
British Standard Code of Practice.
4.2 If the appliance is intended to be installed to a chimney that was previously
used for solid fuel, the flue must be swept clean prior to installation. All flues should
be inspected for soundness and freedom from blockages.
4.3 Any chimney dampers or restrictors should be removed. If removal is not
possible they must be fixed in the open position.
4.4 Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS 5871 Part 2
and in IE reference should be made to the current edition of IS 813 “Domestic gas
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available
4.5 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance.
Please bear this in mind when installing.
4.6 The minimum allowable distance from the outside of the appliance fascia to a
corner wall having combustible material or any other combustible surface which
projects beyond the front of the appliance is 50mm at either side (See figure 1). No
side clearance is necessary to non-combustible surfaces.
