STEP 10: FLUE INSTALLATION
Where the flue passes through the lid of the enclosure the flue
shall be single skin, the triple skin flue must sit on top of the lid
of the enclosure. The lower end of the triple skin casing shall
be close fitting against the lid and must be ventilated.
The triple skin flue will then be continued into the roof cav-
ity and above the roof line, as per Australian & New Zealand
Standard AS/NZ 2918:2018. There must be a 25mm clearance
around the outer triple skin flue, the flue must extend a mini-
mum 1m above the roof line and have a 3m diameter clearance
from the top of the cowl to any objects in a horizontal direction.
**IMPORTANT**
The flue should not include more than two 45
°
degree bends.
The angle of these bends cannot exceed more than 45
°
and can
have no more than one length of 900mm flue between them.

STEP 12: FRONT FRAME
Place a steel frame (minimum 51mm thick) on the front of the
enclosure, ensuring a minimum 25mm clearance to the unit
itself.
STEP 11: DUCTING
The duct MUST be 4 Zero type (aluminium inner core,
aluminium outer, poly insulated, minimum RI.0) and tested to
AS 4254.1-2012. Outlet MUST be metal.
This unit has been supplied with a ducting kit (consisting
of one duct and one metal register), while it is highly
recommended that it is installed, if not installed it will have no
implication on the functioning of the unit.
Cut a hole in the lid of the enclosure nearest to the room where
the heat is to be transferred. Run the ducting from this hole into
the roof space and locate to the room, cut out the plaster and
install a metal register into the ceiling of the next room.
*
*PLEASE NOTE: A maximum duct run of 6m is recommended,
no more than two ducts should run off this cavity.
If an in-line fan is fitted to the ducting kit, then an Outdoor Air
Kit is obligatory and MUST be installed to the unit. All ducting
must be fireproof.
FAN MUST BE METAL AND NOT PLASTIC
