1. WARNINGS
THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL TIMES
IN ACCORDANCE WITH THESE INSTRUCTIONS.
The Forte Flush AG 08 and the Athena Flush AG08 is tested to N.Z. Standards AS/NZS
2 18:2001.
If this heater is incorrectly installed a house fire may result. For your safety follow the
installation instructions carefully.
Do NOT connect the heater to a chimney serving another appliance.
Although the exterior of the heater may appear cool, contact with the unit may cause
burns; warn children and others of the possibility of injury should they touch the heater.
Do NOT dry clothing or unseasoned wood directly in contact with the heater.
Keep all household combustible materials at least 600mm away from front of the heater.
This includes clothing, furniture, wood, newspaper, plastic, matches, etc.
DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS IN THE VICINITY OF
THIS APPLIANCE WHEN IT IS OPERATING.
Use caution when reloading with fuel. Do NOT attempt to load fuel into the heater
when the fire inside the stove is at or near its peak.
Do NOT burn large quantities of paper or combustible material that would create an
extremely hot/quick fire.
Do NOT burn highly coloured paper or brochures (junk mail).
USE ONLY DRY WOOD. AVOID BURNING WET OR GREEN WOOD.
THE USE OF SOME TYPES OF PRESERVATIVE TREATED WOOD AS A FUEL
CAN BE HAZARDOUS.
TIMBER TREATED WITH COPPER CHROMIUM AND ARSENIC TYPE
PRESERVATIVES WILL LEAVE TOXIC RESIDUES IN THE ASH, FIREBOX OR
WITHIN THE FLUE; TIMBER OFFCUTS FROM BUILDING CONSTRUCTION
WILL OFTEN CONTAIN BORIC SALTS. THE COMBUSTION OF THIS
MATERIAL OVER PROLONGED PERIODS CAN PRODUCE ADVERSE EFFECTS
ON REFACTORY LINING IN SOLID FUEL APPLIANCES. EMISSION OF
POISONOUS GASES CAN ALSO BE EXPERIENCED WITH THE BURNING OF
TREATED WOOD.
Driftwood with salt content will also cause rapid deterioration of the heater and should
not be used.

2. FLOOR PROTECTOR REQUIREMENTS
If the heater is to be placed on or within 500mm of a heat sensitive floor, an
i sulated
floor protector will be required.
The insulated floor protector needs to extend under the heater and in front of the door.
See dimensions for floor protector. Similarly a 200mm extension is required on each
side of the door opening unless the insulated floor protector forms an abutment with a
wall or heatshield at a lesser distance.
The heater and floor protector must be fixed to the floor for seismic restraint. Anchor
points are provided in the feet of the unit.
INSULATED FLOOR PROTECTOR CONSTRUCTION
An
I sulated Floor Protector shall consist of a minimum thickness of 40mm ,
consisting of 20mm of an approved insulation material i.e. 2 sheets 10mm micorboard
or superlux, 10mm tile backing board and 10mm tiles or similar on the top surface. All
joints on the upper surface should be sealed to prevent spilt ash from contacting any
heat-sensitive material.
INSERT FLOOR PROTECTOR DIMENSIONS
WHEN BEING INSTALLED IN A MASONRY FIRE PLACE
In a masonry fireplace the standard front clearance from the fireplace glass can be
reduced by increasing the insulated floor protector height.

4. PRE – INSTALLATION
(Refer diagram page 4)
I a Maso ry Fireplace:
Before installing your Firenzo Insert it is important to check the condition of your
masonry chimney. Ensure any cracks are sealed, loose masonry repaired and the
chimney swept.
Check the dimensions of your fireplace opening. Firebricks may need to be removed
and the floor of the opening should be level using mortar if necessary.
Ensure any gaps between chimney face and fireplace surround are sealed with heat
resistant material.
MANTEL – Maso ry Fireplace
If the mantel shelf on a masonry fireplace is of a combustible material there should be a
minimum distance above the top of the fascia of 215mm. This may be reduced if a deflector
or heat shield is fitted under the mantel.
MANTEL – usi g BUILT-IN FIRE CANOPY
FORTE FLUSH – Can NOT have a combustible mantel, however if the mantel is made of a
non heat sensitive material then the minimum distance above the top of the fascia must be
500mm.
ATHENA FLUSH – The minimum distance above the top of the fascia to a combustible or
non-combustible mantel is 500mm.
SIDE SURROUNDS – MASONRY & BUILT IN FIRE CANOPY
Clearance between the fascia and any wooden surround must be 50mm providing the timber
protrudes no more than 100mm.

5. ASSEMBLY INSTRUCTIONS
1 Carefully remove all packaging.
2a If installation is into a MASONRY ENCLOSURE: Remove firebricks as necessary
to fit the firebox into the opening. The firebox front when installed must be flush
with the finished fireplace surround and on a level base of the same height as the
finished floor protector. This may be achieved by using a concrete mix to level the
base.
2b If installation is into a BUILT-IN CANOPY: Construct the canopy box as per page
7 and install into framework following guides on pages 8-14 as applicable.
3 Slide the firebox into the opening so that the outer casing return folds are flush
with the finished fire surround.
4 DUE TO NEW ZEALAND BEING AN EARTHQUAKE PRONE COUNTRY, IT
IS IMPORTANT TO ANCHOR THE INSERT DOWN IN CASE OF EARTH
MOVEMENT. See diagram page 20 showing Typical Insert Installation.
5 Install Flue as per instructions on page 18 and 1 if installing in a masonry fireplace
or page 8, ,10,11,12, 15 if using a Built-in fire canopy (zero clearance box).
6 Now that the firebox and flue are in position,
place 25mm white kaowool
bla ket (supplied) o top of casi g.
7 As this fire sources its combustion air from the chimney cavity/enclosure, the fire
MUST be sealed around the front between the casing and the masonry or inbuilt
canopy. This is achieved by packing the yellow ISB insulation supplied between
the casing and the masonry or inbuilt canopy at the FRONT ONLY to maximum
depth of 0mm.
UNDER NO CIRCUMSTANCES SHOULD THE AIRPORTS ON THE
SIDE OF THE HEATER BE RESTRICTED. Refer diagram page 20.
The fire sources its combustio air from the chim ey cavity, ot from the
room where the fire is i stalled. This ve tilatio air should be draw dow
the chim ey cavity from the air gap set up whe the top spacer bracket
holds the weather collar off from the outer flue casi g e abli g air to be
draw i to the chim ey cavity. Failure to e sure this air supply will starve
the fire of air a d lead to poor performa ce.
8 Assemble and fit the fascia as per instructions on page 21.
NOTE: In the case of some insert fires into existing masonry fireplaces it may be necessary
to install additional adventitious ventilation into the chimney cavity as per AS/N
2918 3.4.1.2 to assist air flow into the fire.. This ventilation should not be
taken/drawn from the room that the fire is installed in.

6. INSERT FLUE SYSTEM
For I stallatio i a Maso ry Fireplace
WARNING; The appliance and flue system
must be installed in accordance with AS/NZS
2 18:2001 and the appropriate requirements of
the relevant building code or codes.
1. Position heater in fireplace. Extend plumb
line from top of chimney, ensuring heater spigot
is in line with top of chimney. If not, flue pipe
offsets will be required.
2. Assemble flue pipes ensuring all seams are in
line and assembly is straight and tight with
crimped ends pointing downwards.
Secure flue pipes with at least 3 stainless steel
or monel rivets and seal.
3. Fasten chimney plate supplied onto the
chimney top. The chimney plate must be
weather sealed with silicone or mortar.
4. Install chimney liner on top of the chimney
plate.
5. Ensure flue pipe is extended over the
chimney liner by 180mm. Secure top spacer
bracket to the flue pipe and ensure slots fit
snugly inside the chimney liner.
6. Slide flashing cone over top of flue, until it
rests firmly over top spacer. Ensure ventilation
gap is not closed off. Secure with pop rivets or
self tapping screws.
7. Fit anti-down draught cowl. Do not secure
as it must be removed for cleaning.
CAUTION: Mixing of flue system components from different sources or modifying the
dimensional specifications of components may result in hazardous conditions. Where such
action is considered the flue manufacturer should be consulted in the first instance.
Refer also to notes on page 19 regarding height of flue system outlet.
