IMPORTANT INFORMATION
Most building regulatory authorities in Australia require any wood heater
installation to comply with Installation Standard AS/NZS 2918. 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 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 REGULATORY 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 result in
hazardous conditions. Where such action is considered, the manufacturer should
be consulted in the first instance.
Caution: Cracked and broken components, e.g. glass panels or ceramic
tiles, may render the installation unsafe.
INSTALLING THE HEATER
2.1. POSITIONING THE HEATER
First review the necessary minimum clearances specified 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.
Alternatively, shielding of the wall(s) can reduce clearances (refer to next
section for more detail).

2.2. 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 on the previous page (“2.1. Positioning the Heater”) 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 thedoor opening, no
less than 200mm both sides of the door opening, and extend under the heater.
| MEASUREMENT | WIDTH |
|---|---|
| Door opening width | 325mm |
| Minimum floor protector width | 725mm |
It may be desirable, e.g. for aesthetic reasons, for the floor protector to be
larger than these minimum dimensions. ”
The floor protector must be no less than 5mm thick, and constructed of non-
combustible material in accordance with AS/NZS 2918.
The floor protector may be laid directly on the combustible floor.
For more details and variations on floor protectors refer to AS/NZS 2918
Clause 2.2, 3.3.1, & 3.3.2
REDUCING CLEARANCES TO COMBUSTIBLES
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 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 Form 2 is 500mm.
A 12mm gapped shield on the wall with a factor of 0.40.
Calculate: 500mm x 0.40 = 200mm. This is the new side wall minimum clearance.
The shielding needs to be large enough so that none of the original clearances
of 500mm are compromised.
INSTALLING THE FLUE
The Nectre Form 2 has been tested in accordance with AS/NZS 2918 with a
ventilated double cased flue system compliant with clause 4.5.1.2 of the
standard.
If installed with an alternative flue system, then the flue system must be
tested to AS/NZS 2918 Appendix F and have a letter of opinion from the
accredited testing authority stating that flue system can be installed on this
heater.
Glen Dimplex is only liable for that which has been tested.
If installed with any anything besides a ventilated double cased flue system,
it is the liability of the installer to ensure the installation is compliant
with AS/NZS 2918.
Full instructions on the flue installation will be supplied with flue kit.
These MUST be followed closely, including minimum exit height from the top of
the floor protector being not less than 4.6m, and minimum exit height above
the roof line or roof ridge as detailed in the instructions.
The flue must be fitted with one of the following flue shielding options:
- Rear flue shield
- Decromesh
- Solid flue shield
Refer to following sections for further details of each flue shielding type.
4.1. REAR FLUE SHIELD:
a. 900 mm long, minimum 160° arc, stainless steel painted black rear flue
shield with 25mm gap between it and the 150mm diameter active flue.
4.2. DECROMESH:
a. Note – Decromesh flue shield must be installed with ventilated locating
ring at base of flue shielding.
b. Full length, half radius perforated decromesh flue shield extending from
the heater through into drop box penetrating the ceiling with perforated
surface facing the front.
c. The manufacturer’s ‘locating ring’ must be used to support the flue
shielding up off the heater top. It is important that air can be drawn into
base and rear of flue shielding.
d. 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. Slide
the shielding over the active flue. Locate the bottom of the decromesh inside
the locating ring.
4.3. SOLID FLUE SHIELD:
a. Note – Solid flue shield must be installed with an internal heat
shield/reflector AND ventilated locating ring at base of flue shielding.
b. Full length solid outer flue shield casing (7.75” diameter) extending from
the heater through into drop box penetrating the ceiling.
c. The internal heat shield/reflector must be a minimum of 900mm tall and
fitted inside the first length of solid outer flue shield, positioned to the
rear of the active flue and located centrally between the active flue and
outer shield.
d. The manufacturer’s ‘locating ring’ must be used to support the flue
shielding and inner shield up off the heater top. It is important that air
can be drawn into base and rear of flue shielding.
e. 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. If using
solid outer shield, fit inner shield inside outer casing and slide the
shielding over the active flue. Locate the bottom of the solid outer shield
and inner shield inside the locating ring.
4.4. LOCATING RING
Depending on the supplier, the flue shielding can be one of three sizes – 200
mm, 7 ¾ inch, or 8 inch diameter. The supplied locating 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 decromesh. Ensure
that the snipped section is at the rear of the flue, out of sight.
INSTALLING THE FLUE (CONTINUED)
5.1. FITTING FLUE SEAL
Any gaps between the inside of the flue spigot and the active flue should be
sealed. This can be done by wrapping the bottom of the flue with a length of
fibreglass tape.
Alternatively, high temperature stove cement can also be used.
For easier access to flue spigot, Form 2s cast iron top plate can be lifted up
approximately 200mm and supported from below while sealing any gaps between
the flue spigot and the active flue..
INSTALLING VERMICULITE LINING
Place the vermiculite bricks into the firebox as shown in the diagram below.
- Two large bricks with one angled edge – one on either side of the firebox. Place angled edge towards the back of the firebox.
- Two tall and skinny bricks with two angled edges – one on either corner of the firebox. Ensure angled cut meets up neatly with side bricks.\
- One large brick at the rear.
Once bricks are in, fit the retainer over the top to hold them in place.
INSTALLING BAFFLE
- Unwrap baffle, then place inside firebox.
- Raise the baffle, tilting the right side upwards.
- Raise the right side of the baffle over the right baffle rail. Once clear of the right rail, push the baffle to the right side of the heater in order to clear the left baffle rail.
- Once resting on both baffle rails, centralise the baffle so that gaps between each side and firebox are equal.
OUTSIDE AIR CONNECTION
Nectre Form 2 has the ability to be connected to an outside air kit. This
enables the heater to draw air for combustion completely from outside your
home.
This is especially useful in modern, air-tight homes with high energy ratings,
but can be done in any house if desired.
The air intake port for Form 2 can be found on the underside of the firebox –
a 75mm diameter tube. Connect outside air ducting here.
The rear shield of Form 2 has a circular knock out that can be removed with
tin snips to allow 75mm diameter semi rigid ducting to be routed through the
rear of the heaterand connected.
A Nectre Form Series Outside Air Kit is sold seperately.
