2.6 Important Considerations Required For Installation of Matakana 1200 Fire
Read this section thoroughly to plan the desired installation of the Matakana 1200 fire.
Location

Evaluate the location of your outdoor fire, surroundings, and neighboring properties.

The land's topography has a bearing on how the wind and overall environment will affect the
fire and the flue system.

It is essential to decide the type of install structure, masonry, or built-in timber-framed. Also,
decide on the cladding options for finishing and weatherproofing.

Consider surrounding trees, neighboring property boundaries, buildings, or wooden fences.
Locate the Matakana 1200 installation structures at a safe distance from the combustible
objects, trees, shrubs, wood storage piles, buildings, property boundaries, or wooden fences.
Elevation of fire

Decide the height of the fire install from the ground.

It is recommended that Matakana 1200 be installed 550~800mm above the ground to have
easy access and convenience required for cooking,

The floor protector requirement depends upon the elevation of fire above ground.
Floor protector
 For an elevated installation of 350mm and more above the ground, only ash floor protector is
required and should extent a minimum 400mm out from the front wall face of the masonry or
built-in structure.
 For installation below 350mm height, the floor must be non-combustible and should extend a
minimum of 650mm out from the front wall of the masonry or built-in structure.
 Ash floor protectors must be constructed of non-combustible material such as fiber cement
board (e.g., Hardies Tile & Slate underlay), steel sheet, or equivalent. The minimum width of
the floor protector should be 1700mm.
 Larger and thicker floor protectors can be constructed for aesthetic purposes.
Ventilation of the cavity – Fresh air inlet vents
 Ventilation of the masonry or built-in cavity is a requirement for the efficient and safe operation
of Matakana 1200 outdoor fire. The ventilation inlet opening should be positioned as low as
possible in the cavity. The ventilation outlet at the top can be via additional casings or the
outlet opening close to the top of the cavity or chimney chase.
 The total open area of the fresh air inlet vent at the bottom of the cavity should be a minimum
of 50,000 mm
2
. E.g., Use two cutouts of size 250x200 with 50% open mesh.
 The top of the fresh air intake vents must be not more than 250mm above the fire's base.
 Inlet vents can be on the sides, rear, or bottom of the cavity. Symmetry in venting is preferred.

Vents can be of any size or shape as long as the required total open area is maintained.

The exterior vents must be covered with an appropriate mesh or similar to prevent vermin from
entering the cavity, made weatherproof, and meet the local building code requirements.
Ventilation of the cavity – Warm air outlets vents

The ventilation outlet opening at the top should be a minimum of 30,000 mm
2
. E.g., Use two
cutouts of size 300x100 with 50% open mesh.

Vents can be of any size or shape as long as the required total open area is maintained.

The exterior vents must be covered with an appropriate mesh or similar to prevent vermin from
entering the cavity, made weatherproof, and meet the local building code requirements.

Alternatively, the cavity or the chimney chase can be vented at the top using additional flue
casing. For masonry installation, 400mm casing will be required. For a built-in/ZC
installation, 450 casing will be required.
Masonry cavity

All masonry construction and cladding must be constructed to suit an outdoor environment as
per the NZ building code.

Use minimum 75mm thick brick, Hebel, or concrete blocks for building masonry cavity
