4.4Concrete Cavity Venting
•The concrete cavity requires air intake venting. Intake air vents can be any size or shape, provided that the total
combined open surface area is a minimum of 28000mm2 (e.g. 2x 75mm Ø vents).
•Intake vents can be on the sides, back or front of the cavity. Vent air must come from an external space and not
the building cavity. Vents can be no higher than 300mm above the base of the fireplace.
•Concrete cavity is vented out by way of the 550mm Ø casing and the casing cover.
4.5Hearth
•A Hearth or Heat Resistant Floor Protector will be required when the fire is at 790mm or above from floor level to the
Fireplace opening. Hearth sizes (measured from the fireplace opening):
•1348mm W x 300mm D (EK950)
•1647mm W x 300mm D (EK1250)
•1947mm W x 300mm D (EK1550)
•When the Fireplace is installed below 790mm from floor level to Fireplace opening, a 1000mm deep, heat resistant
and non-combustible, hearth surface and structure in front of the fireplace can be installed strictly in accordance
with AS/NZS2918 or the entire floor is fully non-combustible or heat resistant.
4.6Mantel
•Any mantel must be fully heat-resistant and non-combustible.
4.7Fireplace Platform
•The Fireplace must be installed onto a non-combustible platform that is suitably designed to take the load of the
Fireplace and Flue.
•If the platform is constructed of a combustible material, the platform must be insulated from the fireplace, using
75mm thick AAC Panels, Calcium Silica Board or concrete of 140mm thickness.
•The platform must not inhibit air flow through the chimney cavity.
4.8Seismic Restraint
•The fireplace must be fixed through the base of the appliance into the platform that supports it, not any insulating
material.
4.9Finishing
•When attached to the main
envelope of the building the
installation must comply with local
Building Code Requirements for
weathertightness. This is not the
responsibility of Escea.
•Claddings or finishes applied to the
front, sides or back of the concrete
cavity must be heat resistant and
non-combustible.
4.10Flue
•The EK Series fires use a 350-450-
550mm Ø flue system with a 650mm
Ø Anti-Down Draught Cowl and
Casing Cover. The EK950 and
EK1250 have a single flue, while the
EK1550 has a twin flue.
•Refer to Sec. 7 for Flue
Specifications.
