This appliance must be fitted on a flat, non-combustible base of minimum

incandescent material is at least 225mm above the floor level. For the customers
safety, and in accordance with BS 5871-2, the fitting of a hearth panel or physical
barrier should be carried out. Should this advice not be followed however, please
give consideration to the safety of the occupants in the room to which the
appliance is installed.
Any hearth panel or physical barrier that is fitted should project a mnimum of
300mm forwards from the fire opening and 150mm either side of the fire
opening, as shown below in Fig. 3 Any physical barrier must be securely fixed and
be of robust design.
