INSTALLATION

INSTALLING THE HEATER

POSITIONING THE HEATER

First review the necessary minimum clearances specified before considering where to position the heater. Thes e clearances c an 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 c an 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) c an reduce clearances (refer to next section for more detail).

STANDARD INSTALLATION****
CORNER INSTALLATION****

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 the door opening, no less than 200mm both sides of the door opening, and extend under the heater.
- 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 Claus e 2.2, 3.3.1, & 3.3.2

REDUCING CLEARANCES TO COMBUSTIBLES

If it is necessary to install a heater clos er 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 s o 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 c as ed flue system compliant with claus e 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 c an be installed on this heater.
Glen Dimplex is only liable for that which has been tested.
If installed with any any thing 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 . Thes e MU ST be followed clos ely, 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 s ections for further details of each flue shielding type.

RE AR FLUE SHIELD:
900 mm long, minimum 160° arc, stainless steel painted black rear flue shield with 25mm gap bet ween it and the 150mm diameter active flue.

DECROMESH:

Note – Decromesh flue shield must be installed with ventilated locating ring at base of flue shielding.
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 .
The manufacturer ’s ‘locating ring’ must be us ed to support the flue shielding up off the heater top. It is important that air c an be drawn into base and rear of flue shielding.
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.

SOLID FLUE SHIELD:

Note – Solid flue shield must be installed with an internal heat shield/reflector AND ventilated locating ring at base of flue shielding.
Full length solid outer flue shield casing (7.75” diameter) extending from the heater through into drop box penetrating the ceiling.
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 bet ween the active flue and outer shield.
The manufacturer ’s ‘locating ring’ must be us ed to support the flue shielding and inner shield up off the heater top. It is important that air c an be drawn into base and rear of flue shielding.
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.

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. B end 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 .

FITTING FLUE SEAL

Any gaps bet ween 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 c an also be used.
For easier access to flue spigot , Form 2s cast iron top plate c an be lifted up approximately 200mm and supported from below while sealing any gaps bet ween the flue spigot and the active flue..

INSTALLING VERMICULITE LINING

Place the vermiculite bricks into the firebox as shown in the diagram below.
1. Two large bricks with one angled edge – one on either side of the firebox. Place angled edge towards the back of the firebox.
2. Two tall and skinny bricks with t wo angled edges – one on either corner of the firebox. Ensure angled cut meets up neatly with side bricks.
3. 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 s o that gaps bet ween 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 c an be done in any house if desired.
The air intake port for Form 2 c an 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 c an be removed with tin snips to allow 75mm diameter semi rigid ducting to be routed through the rear of the heater and connected.
A Nectre Form Series Outside Air Kit is s old seperately.
