Most building regulatory Authorities in Australia require any
wood heater installation to comply with Installation Standard
AS/NZS 2918:2001. Different states and councils may have
varying regulations. Check local building regulations before
installing the appliance.
All Nectre wood heaters have been tested to ensure that they
will meet the appropriate safety Standard requirements if the
instructions in this manual are followed. As the safety and
emissions performance can be affected by altering the
appliance, no modifications are allowed without written
permission from the manufacturer.
WE RECOMMEND THAT THE INSTALLATION OF YOUR
NECTRE WOOD HEATER BE CARRIED OUT BY A QUALIFIED
INSTALLER.
WARNING: THE APPLIANCE AND FLUE SYSTEM SHALL BE
INSTALLED IN ACCORDANCE WITH AS/NZS 2918:2001 AND
THE APPROPRIATE REQUIREMENTS OF THE RELEVANT
BUILDING CODE OR CODES.
WARNING: APPLIANCES INSTALLED IN ACCORDANCE WITH
THIS STANDARD SHALL COMPLY WITH THE REQUIREMENTS
OF AS/NZS 4012 & AS/NZS 4013 WHERE REQUIRED BY THE
REGUALTORY AUTHORITY, I.E. THE APPLIANCE SHALL BE
IDENTIFIABLE BY A COMPLIANCE PLATE WITH THE MARKING
‘TESTED TO AS/NZS 4012 & AS/NZS 4013’.
ANY MODIFICATION OF THE APPLIANCE 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 4012 & AS/NZS
4013.
CAUTION: MIXING OF APPLIANCE OR FLUE-SYSTEM
COMPONENTS FROM DIFFERENT SOURCES OR MODIFYING
THE DIMENSIONAL SPECIFICATION OF COMPONENTS MAY

2.1 Fitting rear heat shield
The rear outer heat shield should be fitted with spacers
before working out the position of the heater and the
relevant clearances to combustible surfaces.
i) On the rear of the heater, there are four 32mm long PK
screws fixing the outer heat shield to the inner heat
shield. Remove the screws and the outer heat shield.
ii) Remove the four M4 x 6mm long screws from the outer
heat shield.
iii) Remove and unwrap the black angled heat deflector
from inside the heater.
iv) Line up the four holes on the angled deflector with the
four holes on the outer heat shield, re-insert the four
M4 screws and tighten.
v) A plastic packet with four 20mm long tubular spacers
will be inside the heater. Relocate the four 32mm long
PK screws through the original holes in the outer rear
heat shield, slide a spacer over each screw, and re-
fasten to the inner rear heat shield.

2.2 Positioning the Heater
First review the necessary clearances specified below before
considering where to position the heater along with the
appliance dimensions in Section “8. Technical Drawings”.
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, eg.
stone, brick, or concrete. If non-combustible material,
distance can be reduced to 100 mm. 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.

2.3 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 in above (Section 2.2) are the minimum
required for the floor protector. It must extend no less than
300 mm in front of the door opening, no less than 275mm
either side of the door opening, and extend under the heater.
Minimum dimensions for floor protector are 900mm wide by
900mm deep. It may be desirable, for example aesthetic
reasons, for the floor protector to be larger than these
minimum dimensions.
The floor protector shall be constructed of non-combustible
material no less than 15mm thick and with a thermal
conductivity not greater than 0.33W/m ºK, eg. 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 2 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 Nectre 15 LE is 750 mm.
A 12mm gapped shield on the wall with a factor of 0.40.
Calculate:- 750 mm x 0.40 = 300 mm. This is the new side
wall minimum clearance.
The shielding needs to be large enough so that none of the
original clearances of 750 mm 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 either 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, OR
2) Decro-mesh with 900mm long inner shield :–
a) A full length, half radius perforated decro-mesh flue
shield extending from the heater through into the
drop box penetrating the ceiling.
b) A 900 mm half round stainless steel inner reflector
must be fitted inside the decro-mesh. Using tin-
snips, cut three 10mm tabs into the top and bottom
of the inner reflector. Bend the centre tabs in, and
the ones closest to the edge out to create an air gap
between it, the outer decro-mesh, and the 150mm
active flue.

c) Use the two ‘Z’ spacers supplied in the plastic
packet in the heater to support the decro-mesh and
inner shield up off the top of the heater. It is
important that air can be drawn into the base and
rear of the decro-mesh.
With a Ø4.3mm drill bit, drill a hole approximately
40mm round from the perforated edge and 10mm
up from the bottom. Do the same on the other side
relative to the other perforated edge.
With the two supplied PK screws, screw the “Z”
spacers to the inside of the decro-mesh.
Place the first length of 150mm active flue into the
flue spigot of the heater. With the 900mm inner
shield fitted inside the decro-mesh with the spacers
attached, slide the decro-mesh over the active flue.
Locate the tabs of the “Z” spacers between the flue
spigot and the active flue.
Warning: Do not install the locating ring if supplied
with the decro-mesh kit as this will restrict the air
flow.
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.

1) Remove the box of bricks from inside the heater.
2) Ensure that the 6mm steel baffle plate is orientated
inside the firebox so that the 75mm fold is at the front
and directed upwards. Raise the front of the baffle plate
up until it clears the two support rods at the front. Slide
the baffle forward until the rear edge has cleared the
two support rods at the back. Raise the rear of the
baffle and slide back so that it is supported in a
horizontal orientation and pushed all the way back in
the firebox.
3) Lift up the steel angle brick retainer and fit the bricks
standing on end around the sides and back of the
heater. There may be some gaps left between the
bricks, but this is not an issue since they will fill up with
ash as the heater is used. Refer to the diagram below for
brick configuration.
