The opening WIDTH and HEIGHT dimensions should be between 365mm and 440mm wide, and 540mm to
575mm high.
Opening DEPTH should be 285mm. Opening DEPTHS include any plaster or infill panels which form part of the

Any existing under grate draught device must be sealed off.
The opening wall must be non-combustible and have adequate flat surface for appliance sealing.
The appliance requires a hearth with non-combustible surface of at least 12mm thick. The top surface must be at
least 50mm above the surrounding floor level, or be surrounded by a raised edge or fender 50mm high.
To enable the products of combustion to be cleared properly up the flue, the outlet at the back of the appliance
must have a minimum 50mm clearance between it and the back wall of the opening or other obstruction. The
area immediately above the outlet must form a smooth path into the flue. 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

Combustible materials, such as wood, may be fitted to within 100mm (4in) of either side of the frame of the fire-
place 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.
