POSITIONING THE OPEN FIREPLACE
First review the necessary clearances specified below before considering where to position the open fireplace. Also check
the practicability of installing the flue system in relation to any obstructing roof beams before positioning the fireplace.
These clearance distances can only be reduced if the surrounding walls are made of non-combustible material, eg. Stone,
brick, or concrete. If non-combustible material, distance can be reduced to 100 mm. Alternatively, shielding of the wall(s) can
reduce clearances (refer to next section for more detail).
The height of the open fireplace firebox above the floor can affect the minimum distance the floor protector must extend out
in front as well as the materials it is constructed from.

FLOOR PROTECTOR (HEARTH)
Unless the open fireplace will be standing on a heat resistant floor such as concrete slab with slate or tiles, it will be necessary
to provide a floor protector.
The construction and dimensions of the floor protector depends on the height of the open fireplace firebox above the floor see below for detail on minimum requirements for this. It may be desirable, e.g. for aesthetic reasons, for the floor protector to
be larger than these minimum dimensions. Non-combustible tiles may be laid over the top of either floor protector.
For more details and variations on floor protectors refer to AS/NZS 2918 Clause 2.2, 3.3.1, & 3.3.2.

INSTALLING THE FLUE (CONTINUED)
Procedure:
1.
Installing 8 inch active flue – the first length of 8 inch
stainless steel flue inserted into the spigot of the
appliance can be differentiated by the other three
lengths by a larger crimp and swage at one end.
Install the remaining three lengths of 8 inch flue as
normal.
2.
10 inch outer casing with external shield – the
first length of outer casing, resting on top of the
appliance, is the slotted length with the external
heat shield. Orientate the outer casing so that the
external shield is closest to the rear wall.
3.
10 inch outer casing with internal shield – the
second length of outer casing, inserted into the
first length, is the one with the internal heat shield.
Orientate the second length of outer casing so that
the internal shield is closest to the rear wall.
4.
Additional black-painted 10 inch outer casing
– depending on the height of the ceiling above
the appliance, it may be necessary to order an
additional length of 10 inch stainless steel outer
casing painted black so that it may extend into the
ceiling drop box.
All other aspects of the flue kit must be installed in
accordance with AS/NZS 2918.

ENCLOSURE VENTILATION
The enclosure must be ventilated. The purpose of the vents is to allow cooler air to be drawn into the enclosure through the
bottom vents, and warm air out through the top vents via natural convection back into the room.
Two vents, each with a minimum free area of 14,700mm2, fitted on either side of the enclosure, not more than 200mm
above the floor AND two additional vents, each with a minimum free area of 7350mm2, fitted on either side of the
enclosure, not more than 200mm below the ceiling.
Ensure that adequate ventilation from the lower vents can get past the open fireplace cabinet.
