    The cavity specifications vary depending on fascia type. The dimensioned drawings below show the size of opening that must be created to fit the ST900. The wall directly above the fire should be finished / gibbed / lined after the fire has been installed, unless there is an access hatch or the chase is open to the ceiling cavity, which allows the flue to be installed after the wall has been lined.

    Hearth and Floor Clearances: There should be at least 100mm between the bottom of the ST900 fire and any horizontal surface below, for example hearths and floors. Wall and Cabinet Clearances: There must be a minimum of 100mm from the sides of the fascia to any protruding side walls or cabinetry.
