B3 Cavity Base
This appliance MUST be fully supported on its base. The base must extend over the entire area
of the underside of the appliance. The base must also be levelled to prevent vibration from
possible fan imbalance. The base of the cavity must be strong enough to support the total
product weight, which is approximately 65kg (DL850) and 80kg (DL1100), depending on fuel
bed.
B4 Hearth
The base of the appliance must be installed a minimum of 100mm o the floor, unless the
appliance is being installed at floor level in which case a hearth is required, made from non-
combustible material, which must extend no less than 300mm from the front of the fire.
This hearth should be at least as wide as the fire’s outer fascia and no less than 10mm thick.
Raised hearths can be any size but must also be constructed from non-combustible materials.
The floor in front of this hearth will still get warm so if the floor covering is vinyl, nylon carpet
or another heat sensitive material then we recommend extending the hearth to 450mm from
the fire. A raised hearth can be of any size but must be constructed from non-combustible
materials.
Squared Lite FASCIA ONLY: The fascia must not be installed ush against a hearth as the
replace draws air from the lower surface of the fascia. As such the fascia must be raised a
minimum of 25mm from a hearth. For fascia measurements, see section B9 on page 11.
