If the appliance is to be fitted against a wall with combustible cladding, the
cladding must be removed from the area covered by the outer surround. The cladding
must also not touch the surround. (See figure 4). We suggest that the actual surround is
used as a template to mark the area for combustible cladding removal and that this area is
increased by at least 2mm all round.

The minimum allowable distance from the outside of the appliance case to a corner
wall having combustible material or any other combustible surface which projects
beyond the front of the appliance is shown in figure 5.
A 10mm access clearance from a non-combustible surface is necessary at the left side.
See figure 5.

Proprietary terminals must comply with BS 715 or BS 1289. Any terminal or
termination must be positioned in accordance with BS 5440 Part 1 to ensure that the
products of combustion can be safely dispersed into the outside atmosphere. Where the
appliance is connected to an unlined brick chimney it is generally unnecessary for the
chimney pot to be replaced or for a terminal to be fitted unless the flue has a diameter
smaller than 170mm.
