SITE REQUIREMENTS
The fireplace opening should be inspected and repairs made where necessary. Any chair brick or fireback may be left in situ, providing that
the dimensional requirements for debris collection space and spigot clearances are met. See diagram below.
The opening WIDTH and HEIGHT dimensions should be between 380mm and 450mm wide, and 540mm to 575mm high. For flues used
with solid fuel, minimum WIDTH is 380mm.
Opening DEPTH should be 128mm (140mm - Multiflue) or greater for a clay/cement lined or pre-cast flue which is new, unused or previously
only used with a gas fire. DEPTH should be 168mm (180mm - Multiflue) or greater for a flue which has previously been used for a solid fuel
or oil burning appliance. Opening DEPTHS include any plaster or infill panels which form part of the installation.
This appliance requires a natural draught flue system which may be one of the following;
225mm x 225mm (9in x 9in) brick or stone.
125mm (5in) minimum diameter lined brick or stone.
125mm (5in) minimum diameter twin wall flue conforming to BS 715.
Pre-cast block flue complying with BS 1289.
Any existing under grate draught device must be sealed off. The opening wall must be non-combustible.
The appliance requires a hearth with non-combustible surface of at least 12mm thick. The top surface must be at least 50mm above the sur-
rounding floor level, or be surrounded by a raised edge or fender 50mm high.
To enable the product of combustion to be cleared properly up the flue, the outlet at the back of the appliance must have a 50mm minimum
clearance between it and the back wall of the opening or any other obstruction. The area immediately above the outlet must form a smooth
path into the flue.
F
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 fireplace opening, providing the forward projection does not exceed 100mm (4in). Any com-
bustible 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.
