ENIGMA II SLIMLINE SLIDE
Installation Instructions
SECTION EIGHT Siting the Appliance Continued
•
CLASS TWO
Fabricated metal
A double-walled or insulated metal flue box built to the requirements of BS 715 with a minimum
diameter of 125 mm (5 ins) and a minimum effective overall height of 3 metres (10 ft).
IMPORTANT: - Do not fit the restrictor plate if the appliance is installed into this type of
flue.
Note: If the flue box is to be used with an existing brick or stone chimney a 125 mm (5
ins) minimum diameter flue liner conforming to BS 715 should be used.
Dampers or register plates must not restrict any of the above flues. The flue must only
service a single appliance and not have any branches or traps that may impede the
natural draught. If a terminal is fitted it must be suitable for the purpose (see 'Approved
Flues & Terminals' published by BG Technology Certification Services).
• The front face (a minimum size of 605 mm (or 555mm for the SF(tlc)Lo) x 505 mm wide) and
the base of the fireplace opening must be flat to ensure that a good seal is formed between
the rear and base of the appliance and the chimney to avoid any reduction of natural
draught.
• A non-combustible hearth must be provided beneath the appliance within the fireplace
opening, a fire-resisting hearth must also be provided symmetrically disposed about the
fireplace opening a minimum thickness of 12 mm with the perimeter 50mm above floor level.
With a minimum width of 640mm and a depth of 300 mm (add the spacer width to the hearth
depth if a spacer is to be fitted i.e. for a 42mm spacer the hearth depth would be 342mm).
• Any combustible material above the opening must be removed up to a minimum height of
590 mm above hearth level.
• Purpose-built superimposed fire-resistant hearths and back panels, specified as suitable by
the manufacturers, may be used, or a suitable proprietary fire surround with a 100
o
C rating
(minimum).
Clearance to Shelf or Surround
To check the compatibility of a
combustible shelf or surround, refer to
the chart.
Clearances at side of fire
Minimum width between vertical sides
of combustible surround should not be
less than 700 mm provided fire is
central to surround and sides do not
project more than 150 mm. When
vertical side forward projection is
increased by 12.5 mm add 50 mm to
inside width of surround.
N.B. When fire is fitted this gives a
minimum side clearance of 100mm.
A minimum of 30mm clearance is
required to non-combustible surfaces
to allow access to the control and for trim removal.
