STEP 9: CAVITY LID
**IMPORTANT**
SIDE VENTS
It is highly recommended the cavity lid be installed flat to ensure
sufficient air flow around the appliance if 2 vents are used.
FRONT VENTS
It is highly recommended the cavity lid be installed on an angle
of 15° facing the front of the fireplace to ensure sufficient air
flow around the appliance.
STEP 10: 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.
A typical ducting kit will comprise of two ducts and two metal
registers. If not installed it will have no impact on the function
of the fireplace
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 desire room.
**PLEASE NOTE: A maximum duct run of 6m is recommended,
A maximum of four ducts can be run off the Axis H1200,
H1200DS, H1400 and EPI950 models, and a maximum of
six ducts for the Axis H1600, H1600DS, H1600XXL and
H1600XXLDS models.
The cavity lid must be installed 500mm below the ceiling and
be comprised of the following; minimum 3mm minimum thick
steel plate for support, followed by a 12mm thick heat resistant
sheet, with 1 x 25mm Rockwool sheet. A hole is to be cut in
the centre of the lid in order for the single skin flue to penetrate
through tightly. You may also use a heat resistance sealant (i.e.
Firecork) and heat proof tape to seal any air gaps.
It is important to ensure the cavity lid is fully sealed to all
edges.
