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 on top of the firebox 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
below.
A non-combustible shelf may be fitted to within 10mm of the top edge of the fireframe. Combustible materials,
such as wood, may be fitted to within 100mm (4in) of either side of the frame of the appliance, 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.
As with all heating appliances, any decorations, soft furnishings, and wall coverings (i.e. flock, blown vinyl and
embossed paper) positioned too close to the appliance may discolour or scorch.
