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 Blaze 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 BLAZE
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

RESULT IN HAZARDOUS CONDITIONS. WHERE SUCH ACTION

IS CONSIDERED, THE MANUFACTURER SHOULD BE

CONSULTED IN THE FIRST INSTANCE.

CAUTION: CRACKED AND BROKEN COMPONENTS, EG. GLASS

PANELS OR CERAMIC TILES, MAY RENDER THE INSTALLATION

UNSAFE.

2.1 Positioning the Heater

First review the necessary clearances specified below before

considering where to position the heater.

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).

2.2 Floor Protector (Hearth)

Unless the FS 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 2.1) are the minimum

required for the floor protector. 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 15mm minimum

thick fibre cement sheet with thermal conductivity not

greater than 0.33W/m ºK. 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

Gap 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 FS 800 LE is 425mm.

A 12mm gapped shield on the wall with a factor of 0.40.

Calculate:- 425mm x 0.40 = 170mm. This is the new side wall

minimum clearance.

The shielding needs to be large enough so that none of the

original clearances of 425mm are compromised.
