Baffle Plate” for details.
Bricks & Brick Retainers
To install the bricks and brick retainers, refer to section “7.
Installing The Fire Bricks” for details.
Ash Plate
The ash plate will arrive assembled. To replace the ash plate,
refer to section “2. Replacement of Ash Plate” in the
Operating Instructions for details.
3.1 Positioning the Heater
First review the necessary minimum clearances specified
below before considering where to position the heater. These
clearances can be greater if desired.
Also check the practicability of installing the flue system in
relation to any obstructing roof beams before positioning the
heater.
These clearance distances can only be reduced if the
surrounding walls are made of non-combustible material, e.g.
Stone, brick, or concrete. If non-combustible material,
distance can be reduced to 100mm. Alternatively, shielding of
the wall(s) can reduce clearances (refer to next section for
more detail).
Depending on the type of flue shielding used, the clearances
to combustible surfaces varies.

3.2 Floor Protector (Hearth)
Unless the heater will be standing on a heat resistant floor
such as concrete slab with slate or tiles, it will be necessary to
provide a floor protector (hearth).
The dimensions given above (Section 3.1) are the minimum
required for the floor protector to extend beyond the firebox
door opening. It must extend no less than 300 mm in front of
the door opening, no less than 200mm either side of the door
opening, and extend under the heater.
It may be desirable, for example aesthetic reasons, for the
floor protector to be larger than these minimum dimensions.
The floor protector can be constructed of either: -
a) toughened glass no less than 10mm thick, OR
b) Non-combustible material no less than 7.5mm thick
and with a thermal conductivity not greater than
0.33W/m ⁰K, e.g. compressed cement sheet.
The floor protector may be laid directly on the combustible
floor.
For more details and variations on floor protectors refer to
AS/NZS 2918:2001 Clause 2.2, 3.3.1, & 3.3.2.
If it is necessary to install a heater closer to a combustible
surface than the stated requirements in Section 3 of this
Installation Guide, it must be done in accordance with
Australian Standard AS/NZS 2918:2001 Section 3, Tables 3.1 &
3.2.
Shield Construction: The shield shall be constructed from a
heat resistant material. The shield must be fixed to the surface
that requires protection and NOT the heater.
The Standard allows three options to reduce stated
clearances.
Single layer of continuous material with Minimum Air Gap of
12mm—Clearance Factor = 0.40
Single layer of continuous material with Minimum Air Gap of
25mm—Clearance Factor = 0.30
Two spaced layers of continuous material with Minimum Air
Gaps of 12mm + 12mm—Clearance Factor = 0.20
The shielding must be open at the top and bottom (vented) to
allow a continuous air flow. It is this air flow that keeps the
surface requiring protection cool. Fixings should not impede
this air flow.
The shielding needs to go far enough along and up the wall so
that the original side and rear required clearances are not
compromised. As the flue is now closer to the wall the
shielding should also protect the wall from the flue pipe.
For example:
Side wall clearance for the B100 is 700mm.
A 12mm gapped shield on the wall with a factor of 0.40.
Calculate: - 700mm x 0.40 = 280mm. This is the new side wall
minimum clearance.
The shielding needs to be large enough so that none of the
original clearances of 700mm are compromised.

The flue system used when installing the heater MUST comply
with the current installation standard AS/NZS 2918.
Full instructions on the installation of the flue will be supplied
with the flue kit. These MUST be followed closely, including
the minimum exit height from the top of the floor protector
being not less than 4.6m, and the minimum exit height above
the roof line of roof ridge as detailed in the instructions.
The flue must be fitted with one of the following:
1) Rear flue shield – 900 mm long, minimum 160° arc,
stainless steel unpainted rear flue shield with 25mm gap
between it and the 150mm diameter active flue, and
25mm above the top of the heater, OR
2) Decro-mesh –
Note: MUST be installed with the manufacturer’s 490mm
tall inner shield AND ventilated decro-mesh locating ring.
A full length, half radius perforated decro-mesh flue shield
extending from the heater through into the drop box
penetrating the ceiling with the perforated surface facing
the front.
The 490 mm half round stainless steel inner reflector
supplied with heater must be fitted inside the decro-mesh.
The manufacturer’s decro-mesh ‘locating ring’ must be
used to support the decro-mesh and inner shield up off
the heater top. It is important that air can be drawn into
the base and rear of the decro-mesh.
Place the locating ring above the flue spigot (resting on the
top plate) and then place the first length of 150mm active
flue into the spigot. With the 490mm inner shield fitted
inside the decro-mesh, slide the decro-mesh over the
active flue. Locate the bottom of the decro-mesh and inner
shield inside the locating ring.
Depending on the supplier, decro-mesh can be one of
three sizes – 200 mm, 7 ¾ inch, or 8 inch diameter. The
decro-mesh ring will fit the two smaller diameters but
not the 8 inch. In this scenario, snip through the outer
ring with tin-snips as shown in the drawing below. Bend
the two “arms” in a little so they ends don’t project out
when fitted to the decro-mesh. Ensure that the snipped
section is at the rear of the flue, out of sight.
If the draft is insufficient or periodic down drafting occurs and
the heater smokes or only burns slowly, extending the flue or
fitting a specialist cowl will usually resolve the issue.

The baffle plate should be installed before installing the fire
bricks.
1) Place the baffle inside the firebox with the trapezium
fold directed upwards and at the front of the firebox.
(refer to following diagram for correct orientation).
2) Raise the front of the baffle, tilting it back so that it
clears and rests on the front support rods.
3) Raise the rear of the baffle, bringing it forward enough
to clear the rear support rods.
4) Once clear of the rear support rods, push the baffle
back so that it is resting hard up against the rear of the
firebox.
5) Centralise the baffle so that gaps between each side
and firebox are equal.
1) Place lower brick retainers in base of firebox,
centralised and against rear of the firebox.
2) Place three bricks along the back.
3) Place two medium size bricks along each side.
4) Place upper brick retainers on top to hold the bricks
upright and in place.
