FREE STANDING
STEP 2: CLEARANCES
**IMPORTANT**
The unit must maintain a 1200mm clearance horizontally in
all directions to anything combustible, apart form a ceiling
clearance which is not to be less than 1500mm vertically.
Masonry material can be used as a heat shield to reduce
clearances to the unit and flue system, please refer to
Australian & New Zealand Standards AS/NZS 2918:2018.
STEP 1: HEARTH (FLOOR PROTECTOR)
Where combustible flooring is concerned, lay a masonry base.
This can be made from tiles, granite, slate, concrete, hebel
blocks, etc. The base must be a minimum 75mm thick and
must protrude a minimum of 500mm on all sides of the firebox.
STEP 3: OUTDOOR AIR KIT
(IF NOT REQUIRED GO TO STEP 4)
Any depression or lack of fresh air within the room where the
fireplace is located can cause emanation of smoke to flow
back into the room and the unit to run inefficiently. It is highly
recommended that an Outdoor Air Kit be installed in six or more
star rated homes, or any install where a mechanical device (ie.
fan), takes air from the fireplace cavity & transfers it.
STEP 4: INSTALLING FREE STANDING FLUE SYSTEM
The first length of black double skin flue does not have a
crimped end on either side of the flue piece. Place this first
length on the outside of the firebox spigot , ensure the inner
lugs are facing down closest to the firebox so that the second
skin can’t move down and impede on the damper system.
Continue double skin flue to the required ceiling height. The
painted length of triple skin flue (also known as the “Dropper
Box”) is to extend 150mm below the ceiling. Please refer to
Australian & New Zealand Standard AS/NZ 2918:2018
