STEP 10: CAVITY LID
**IMPORTANT**
SIDE VENTS
It is highly recommended the cavity lid be installed flat to
ensure sufficient air flow around the appliance.
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.
The cavity lid must be installed 300mm below the ceiling and
be comprised of the following; minimum 3mm 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.
STEP 11: SIDE WALLS
Attach a heat resistant material from the base to the top of the
ceiling on the sides of the enclosure.
SIDE VENTS
If you are installing your appliance with side vents, ensure you
leave the necessary gaps when constructing the side walls.
(Refer to step 12 & 18)
STEP 12: DUCTING CONTINUED...
Install the ducting to each transition piece and extend into the
roof space and to the desired room(s). Cut a hole in the ceiling
and install a metal register into the ceiling of the room the
vents will be allocated in. If more ducts are required additional
components and duct design is to be provided by the retailer or
installer.
