1. IMPORTANT INFORMATION
Most building regulatory authorities in Australia require
any wood heater installation to comply with Installation
Standard AS/NZS 2918:2018. Dierent states and
councils may have varying regulations. Check local
building regulations before installing the appliance.
The Masport Ligna 700/800/900 open fireplaces
have been tested and comply with the relevant safety
Standard AS/NZS 2918. This installation instruction
manual must be followed to comply with the standard.
As the safety and emissions performance can be
aected by altering the appliance, no modifications
are allowed without written permission from the
manufacturer.
WE RECOMMEND THAT THE INSTALLATION OF
YOUR MASPORT WOOD HEATER BE CARRIED OUT
BY A QUALIFIED INSTALLER.
WARNING: THE APPLIANCE AND FLUE SYSTEM
SHALL BE INSTALLED IN ACCORDANCE WITH
AS/NZS 2918:2018 AND THE APPROPRIATE
REQUIREMENTS OF THE RELEVANT BUILDING CODE
OR CODES.
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.
2. FLUE DAMPER SYSTEM
The Masport Ligna features a flue damper system (see
below). The damper is positioned to rest on a support
during transportation. This must be removed via a pin
and reset so the damper drops down in a natural position
before proceeding. Once reset, the damper can be
operated with the chain.

MASONRY INSTALLATION
4. MASONRY INSTALL OVERVIEW
The Masport Ligna open fireplace can be installed as a built in appliance within a non-combustible masonry enclosure.
Refer to this section for clearance requirements and instructions if the heater is to be in a masonry installation. When
installing your Ligna open fIreplace, please be sure to read these instructions carefully and comply with all clearances.
Step by step installation instructions:
1. Take note of your selected Ligna model and construct the floor protector according to the details in “4.1. Floor
Protector for Masonry Install” on page 4. Position heater on floor protector, and install flues - see “7. Flue
Clearance Requirements” on page 9. Do not restrict convection air intake on the front at base of unit. Ensure
gather is bolted tightly onto unit.
2. Build non-combustible enclosure from masonry, Hebel blocks or equivalent, following the dimensions and
instructions listed in “4.2. Masonry Enclosure” on page 5.
3. Construct timber frame around masonry enclosure according to the dimensions and instructions listed in “4.3.
Timber Frame for Masonry Install” on page 5.
4. Enclose framing with plasterboard/gyprock or timber paneling, ensuring approved clearances are maintained. Front
cladding must be non-combustible to the height of the masonry enclosure.

5
4.2. MASONRY ENCLOSURE
Construct enclosure with a minimum thickness of 75mm
from non-combustible materials i.e. masonry, Hebel
blocks or equivalent. It must completely surround the
sides, back and breast above top of unit. Place insulation
with minimum thickness of 50mm on top of gather and
tuck into enclosure.

ZERO CLEARANCE INSTALL
5. ZERO CLEARANCE INSTALL OVERVIEW
The Masport Ligna open fireplace can be installed as a built in appliance within a zero clearance box. Refer to this section
for clearance requirements and instructions if the heater is to be in a zero clearance installation. When installing your Ligna
open fIreplace, please be sure to read these instructions carefully and comply with all clearances.
Step by step installation instructions:
1. Take note of your selected Ligna model and construct the floor protector according to the details in “5.1. Floor
Protector for ZC Install” on page 6. Assemble ZC box containing heater on floor protector, along with flues - see
“7. Flue Clearance Requirements” on page 9, and separate document “Masport Ligna - Zero Clearance Box
Assembly”. Do not restrict convection air intake on the front at base of unit. Ensure gather is bolted tightly onto unit.
2. Construct timber frame around zero clearance box according to the dimensions and instructions listed in “5.2.
Timber Frame for ZC Install” on page 7.
3. Enclose framing with plasterboard/gyprock or timber paneling, ensuring approved clearances are maintained. Front
cladding must be non-combustible to the height of the zero clearance box.
5.1. FLOOR PROTECTOR FOR ZC INSTALL
Floor protector for a zero clearance install consists of a
5mm thick sheet of compressed fibre cement, with 75mm
bricks positioned on top, or an equivalent construction
material giving the same thermal conductivity or less, with
minimum total thickness of 80mm.
It must extend a minimum of 300mm in front of heater,
underneath the unit covering the entire footprint of the ZC
box, and 200mm either side of the fireplace opening.

5.2. TIMBER FRAME FOR ZC INSTALL
If a timber or combustible studwork is built around the
exterior of the zero clearance box, it must be no closer
than 10mm to the sides, 15mm to the top, and 35mm to
the back of the box.
Note: If Ligna is to be installed elevated from the ground,
a 6mm layer of compressed fibre cement is required
between the base of the ZC box and any timber or
combustible studwork.

7.2. MASONRY FLUE ENCLOSURES
When flue can be completely enclosed by non-
combustible materials such as 110mm brickwork, or 75mm
Hebel blocks, a single skin stainless steel flue system
may be used. Clearance between flue and masonry is not
necessary.
Install procedure:
●Position stainless steel inner active flue (crimped
end down) into collar of spigot. Rivet to collar at 3
points and thereafter 3 at each flue joint.
●Fit cowl into inner stainless steel flue and secure.
Seal and flash flues appropriately.

7. FLUE CLEARANCE REQUIREMENTS
7.1. FLUE INSTALLATION
The Masport Ligna has been tested to AS/NZS 2918 with a double skin flue system. All other aspects of the installation
must comply with this standard.
You can install your Masport Ligna flue system two ways:
●Single skin flue system fully enclosed by masonry. See “7.2. Masonry Flue Enclosures”.
●Double skin flue system from the appliance, through the ceiling and roof penetration. See “7.3. Timber Framed Flue
Enclosures”.
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.
45 degree flue bends can be positioned directly onto the gather collar of the unit. Use at least 2 x 900mm lengths of flue
following last bend upright. Use a minimum 3.6m length of flue from the top of the unit.

7.3. TIMBER FRAMED FLUE ENCLOSURES
7.3.1. BELOW CEILING
Between top of the Masport Ligna open fireplace and
the ceiling, a double-skin flue system must be used – a
stainless steel active with a single outer casing. The outer
casing must be 2 inches (50mm) in diameter larger.
When the unit has been installed within a masonry
enclosure (i.e. not using zero clearance box), ventilation
slots must be cut in to the outer casing as illustrated.
Install procedure:
●Position stainless steel inner active flue (crimped
end down) into collar of spigot. Rivet to collar at 3
points and thereafter 3 at each flue joint.
●Position outer flue casing (crimped end up) over
inner flue and space with 25mm self tapping
screws, 4 at bottom then 4 at each flue casing joint.
Ensure flues are structurally secure.

7.3.2. ABOVE CEILING
The flue system that passes through the ceiling and roof
penetration must be a continuation of the double-skin flue
system extending up from the top of the open fireplace.
This consists of the stainless steel active flue with a single
outer casing. The outer casing must be 2 inches (50mm)
in diameter larger.
A minimum clearance of 50mm must be maintained
between the outer casing and any combustible materials.
Install procedure:
●Install further lengths of stainless steel active flue
as above. Rivet at 3 points at each flue joint.
●Position outer flue casing (crimped end up) over
inner flue and space with 25mm self tapping
screws, 4 at bottom then 4 at each flue casing joint.
Ensure flues are structurally secure.
●Fit cowl into inner stainless steel flue and secure.
Seal and flash flues appropriately.
