1. WARNINGS
This Fire should be Maintained and Operated at all times in accordance with
these instructions.
The Forte Flush AG & Rural and the Athena Flush AG & Rural have been tested to N.Z. Standards
AS/NZS 2918:2001.
If this Fire is incorrectly installed a house fire may result. For your safety follow the installation
instructions carefully.
Do NOT connect the Fire to a chimney serving another Fire.
Although the exterior of the Fire may appear cool, contact with the Fire may cause burns; warn children
and others of the possibility of injury should they touch the Fire.
Do NOT dry clothing or unseasoned wood directly in contact with the Fire.
Keep all household combustible materials at least 600mm away from front of the Fire. This includes
clothing, furniture, wood, newspaper, plastic, matches, etc.
Do not use FLAMMABLE LIQUIDS or AEROSOLS in the vicinity of this Fire when it is operating
Use caution when reloading with fuel. Do NOT attempt to load fuel into the Fire 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 25% or less moisture contact. AVOID BURNING WET OR GREEN WOOD.
The use 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 refractory lining in
solid fuel Fires. 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 Fire and should not be used.

2. INSTALLATION RESPONSIBILITIES
Warning: The Fire and Flue system must be installed in accordance with AS/NZS 2918:2001 and the
appropriate requirements of the relevant NZ Building Code or Codes. If the flue system has been
AS/NZS 2918:2001 Appendix F tested by the flue system manufacturer then their specifications for the
installation of the flue system must be adhered to.
Any modification of the Fire that has not been approved in writing by the testing authority is considered
to be in breach of the approval granted for compliance with AS/NZS 4013.
Caution: Mixing of Fire or flue-system components from different sources or modifying the
dimensional specification of components may result in hazardous conditions. Where such action is
considered, the manufacturer should be consulted in the first instance.
Strict adherence to these instructions will meet these standards. Any variation from these installation
instructions or any doubt about them must be checked against the requirements of the standards.
Please leave this manual with the owner when installation is complete.
3. FLOOR PROTECTOR REQUIREMENTS
If the Fire is to be placed on or within 500mm of a heat sensitive floor, an insulated floor protector will
be required.
The insulated floor protector needs to extend under the Fire 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 heat shield at a lesser distance.
The Fire and floor protector must be fixed to the floor for seismic restraint. Anchor points are provided
in the feet of the Fire.
INSULATED FLOOR PROTECTOR CONSTRUCTION
An Insulated Floor Protector shall be a minimum thickness of 40mm, consisting of 20mm of an
approved insulation material i.e. 2 sheets of 10mm Micorboard or Supalux, 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.

5. PRE-INSTALLATION
(Refer diagram page 6)
In a Masonry 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 the chimney face and
fireplace surround are sealed with heat resistant material.
MANTEL – Masonry Fireplace
If the mantel shelf is of a combustible material there should be a minimum distance above the top of
the fascia of 400mm. This may be reduced if a deflector or heat shield is fitted under the mantel.
MANTEL – using ZERO CLEARANCE BOX -(Built-in Fire Canopy)
FORTE – 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 – The minimum distance above the top of the fascia to a combustible or
non-combustible mantel is 500mm.
SIDE SURROUNDS – MASONRY & ZERO CLEARANCE BOX - (Built-in Fire Canopy)
Clearance between the fascia and any wooden side surround must be 50mm providing the timber
protrudes no more than 100mm.

6. ASSEMBLY INSTRUCTIONS
1 Carefully remove all packaging.
2a If the 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 ZERO CLEARANCE BOX : Construct the canopy box as per page 8. Install
into framework following guides on pages 8 - 15 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 18 showing
Typical Insert Installation.
5 Install Flue as per instructions on Page 20 & 21 if installing in a Masonry Fireplace or pages 8, 9,
10, 11, 12, 15, if using a Zero Clearance Box - (Built-in Fire Canopy).
6 Now that the firebox and flue are in position, place 25mm White Kaowool Blanket (supplied) on
top of casing.
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 Zero Clearance Box This is achieved by
packing the yellow ISB insulation supplied between the casing and the masonry or Zero Clearance
Box at the FRONT ONLY to maximum depth of 90mm.
UNDER NO CIRCUMSTANCES SHOULD THE AIRPORTS ON THE SIDE OF THE Fire BE
RESTRICTED. Refer diagram page 18.
The fire sources its combustion air from the chimney cavity, not from the room where the fire is installed.
This ventilation air should be drawn down the chimney cavity from the air gap set up when the top spacer
bracket holds the weather collar off from the outer flue casing enabling air to be drawn into the chimney
cavity. Failure to ensure this air supply will starve the fire of air and lead to poor performance.

5. Ensure flue is extended over the chimney liner by
180mm. Secure top spacer bracket to the flue and ensure
slots fit snugly inside the chimney liner.
6. Slide flashing cone over top of flue, until it rests firmly
over top spacer. 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.
