Installation instructions
2.4 HEARTH REQUIREMENTS
The appliance must be placed on a constructional hearth made of solid non-combustible
material, such as concrete or masonry, at least 125 mm thick, including the thickness of
any non-combustible fl oor and/or decorative surface. Combustible material should not
be placed beneath the constructional hearths unless there is an air-space of at least
50 mm between the underside of the hearth and the combustible material, or the
combustible material is at least 250 mm below the top of the hearth.
The minimum depth of the constructional hearth is 500 mm. A superimposed hearth on
top of the constructional hearth must have a minimum depth of 225 mm and must be
free of any combustible material. The actual depth of a superimposed hearth is depen-
dent on the installation height of the appliance. The higher the appliance is installed the
deeper the superimposed hearth should be to avoid scorched fl oor coverings. On the
diagram below the minimum depth of the superimposed hearth in relation to the height
of the appliance can be determined.
