1.0 Introduction
Congratulations!
You are the owner of a state-of-the-art Ultra Low Emission Burner “Masport Hurunui” designed and
developed by Glen Dimplex, New Zealand. Thank you for purchasing a Masport appliance.
The Hurunui ULEB is a new generation wood fire designed to provide you with all the warmth and comfort of
a fireplace while having ULTRA LOW emissions to dramatically reduce the impact on the environment.
Environment Canterbury has approved the installation of this burner in all clean air zones that have been
previously banned for the installation of a conventional wood burner. As it bears the Masport brand, it
promises to provide you with the economy, safety, and efficiency.
To make the most of your appliance, installing, operating, and maintaining the burner correctly is important.
Please read this installation and operations manual carefully before installing or operating your Hurunui
ULEB. Please take the time to understand the basic principles of this new burner which uses the latest
combustion technology.
Your Hurunui ULEB burns less fuel in comparison to a standard LEB while producing a more consistent heat
than a conventional wood burner, producing fewer harmful emissions. The bricks fitted in this burner are
ceramic that retains the invaluable heat and release towards the end of the burn cycle. The baffle is made of
stainless steel, making it durable, and lowers costs in the long run.

Hurunui Installation in Alcove/Recess situation
Hurunui burner models have been tested for alcove (recess) made of combustible material
and comply as per safety standard AS/NZS 2918:2001
Note –
- Refer to the table on
Page-3 for dimensions
- The ceiling height must be
a minimum of 2400mm
3.0 Installation of The Hurunui ULEB
3.1 Unpacking
Remove the shipping wooden crate and packing material around the burner. Remove the loose pieces from the
firebox. Remove and discard the screws holding the wood fire to the shipping pallet. Using appropriate lifting
equipment, move the burner close to its installation position. The installer should use correct lifting procedures to
avoid injury while handling a Masport Hurunui burner.
3.2 Positioning
The Hurunui ULEB is tested to and complies with parallel, corner, and alcove (2.4m ceiling height) wall
configurations, with minimum distances to heat-sensitive materials in accordance with the AS/NZ 2918:2001
safety test standard. Determine the installation position for your Hurunui fire only after considering the necessary
clearances (See Technical Specifications on page 5 of this manual) and checking the practicability of installing the
flue system. No wall or other fixed objects should be closer to the front of the Hurunui burner than two meters.
Regard heat-resistant walls with heat-sensitive surface treatments (e.g., wallpaper or heat-sensitive paints) as
heat-sensitive walls.
Any proposed deviation from the specified clearances or installation configurations should be discussed with a
registered “NZHHA” approved installer or GDNZ’s technical team to ensure that the variation complies with AS/NZ
2918:2001
3.3 Flue Requirements
A minimum 4.2M long, 150mm diameter Masport flue system or flue system that has been tested and complies
with the current installation standard AS/NZS 2918:2001, Appendix F shall be used with the Hurunui burner along
with the 900mm long, Masport St/St double skin flue shield. Clearances to combustible given on section 2.0 have
been determined during a safety test, which was carried out with standard parallel and corner installation
configuration with a minimum 2.4m high ceiling.

7
If a flue exits out of the roof within 3 meters from the ridge, the outer shield shall be not less than 600mm above
the ridge. If the flue exits further than 3 meters out from the roof ridge, then it must project at least 1000mm
above roof penetration. This dimension may need increasing to ensure that the top of the flue is at least 3 meters
away from the roof or other obstruction when measured horizontally.
The flue pipe shall extend not less than 4.2m above the top of the burner. Due to factors such as roof pitch,
predominant winds, nearby obstructions (i.e., trees, buildings), fire placement, flue lengths, and flue
terminations/cowls may vary. (Refer to Figure 3.3.1) Additional components may be required to complete the
installation and meet all AS/NZS 2918:2001 guidelines for flue termination.
Low flue gas temperature can create flue draft issues in the colder environment. It is highly recommended that
the 200 inner casing of Masport flue system be extended within 250~300mm below the flue termination. This is
particularly important for installation in the colder areas of Canterbury and south of the Canterbury region. (Refer
to Figure 3.3.2. Depending upon installation, use the required length of additional flue pipes.
AS/NZS 2918:2001 guidelines should be followed for deviation from these standard configurations. Detailed
instructions for roof penetrations etc., are supplied along with the Masport flue kit. These must be followed
closely, including the minimum flue exit height from the top of the floor protector and the minimum exit height
above the roofline or roof ridge as detailed in the instructions.
Flue installations other than strictly vertical ones are possible. See AS/NZS 2918:2001 for information on non-
vertical flues and flues passing through walls and eaves.
The flue to the flue spigot and all other flue pipe joints should be sealed using firebox cement and Stainless-Steel
Rivets. Sealing all the joints is important for achieving the desired performance of the Hurunui burner.
For flue heat shields other than the 900mm Masport Double Shield, the installation clearances will be in
accordance with the guidelines specified in AS/NZS 2918:2001 for an untested flue installation.

3.4 Floor Protector Requirements
The Hurunui burner can be installed on any non-combustible ash floor protector with minimum dimensions given
on page 4 of this manual. Please note that the dimensions given are minimum, and we recommend using a
slightly larger floor protector size.
Please note that the Hurunui burner is heavy, having a total weight of 130 Kg. The floor and the materials used
as floor protectors should be strong enough to bear this load. The minimum requirements for material to be used
as floor protectors on a combustible material are
- 6mm fibre cement board (e.g., Hardies Tile & Slate Underlay) plus 8mm ceramic tiles on a firm base.
- 4mm mild steel floor protector supplied by Glen Dimplex
- Or equivalent.
3.5 Reducing Clearances
The clearances to combustible specified in section 2.0 of this manual can be safely reduced by following
guidelines specified in AS/NZS 2918:2001 table 3.1 & 3.2.
- Heatshield should be made of non-combustible material like metal or masonry.
- Installed between the burner and the combustible wall
- With an air gap behind it and vented top and bottom
- The shield should extend a minimum of 450mm beyond the top of the appliance and extend width-wise so
that unshielded rear clearance is maintained
Clearance factors for heat shield which is within 45 degrees of the vertical
Heat Shield Construction Minimum Air Gap Dimension Clearance Factor
Single-layer of continuous material 12mm 0.4
Single-layer of continuous material 25mm 0.3
Two spaced layers of continuous material 12mm+12mm 0.2
Clearance factors for heat shield which is more than 45 degrees off the vertical
Heat Shield Construction
Minimum Air Gap Dimension
Clearance Factor
Single-layer of continuous material 12mm 0.8
Single-layer of continuous material 25mm 0.6
Ensure that all such installations meet the local rules and are approved by the local building authorities before the
installation process begins,
3.6 Seismic Restraint
The Hurunui ULEB must be seismically restrained, including the floor protector. The figure below gives the holes
that can be pre-drilled on the floor protector with respect to the flue centre. We recommend a minimum size of
8mm Dyna Bolts on the concrete floor or 8mm coach screws or toggle fasteners for wooden floors of appropriate
length. Two holes are located at the rear of the burner.

3.7 Brick and Baffle Layout
4.0 Operational Instructions for The Hurunui ULEB
Before the first light-up, ensure that the burner is correctly installed and signed off
by an approved installer. All local council's wood fire permission or permit
requirements have been completed satisfactorily.
4.1 Preparing the Burner for First Light-up
Ensure that the St/St Baffle and the 7x ceramic bricks are placed properly as per the brick baffle layout document
583717, which comes with the fire.
4.2 Permitted Fuels
The quality of the firewood you burn can considerably affect the performance of the Hurunui ULEB. Moisture
content, tree species, and log size are the main factors affecting the emissions produced by any wood burner.
The Hurunui ULEB is designed to burn wood fuel that meets the following criteria:
- Less than 25% moisture content
- Has not been treated with preservatives or impregnated with chemicals or glue
- Is not chipboard, particleboard, or laminated board
- Is not painted, stained, or oiled
- Is not driftwood or other salt impregnated wood
Burning materials that do not meet the above criteria can damage the firebox and put you at the risk of voiding the
warranty of the Hurunui ULEB.

In NZ, radiata pine or macrocarpa is the most commonly available softwood species suitable as firewood. Other
hardwood species like eucalyptus (bluegum) can also be mixed with softwood to achieve longer burns.
If you are cutting your firewood, only wood that has been air-dried in a sheltered, well-ventilated stack, preferably
for at least 12 months, may be burned in the Hurunui ULEB. To ensure that the wood has a 25% or less moisture
content, store it under a roof and protect against heavy rain. If you purchase firewood, buy firewood that is well
seasoned and has a moisture level below 25%. We recommend "Good Wood" merchants approved by your local
council.
Do not burn coal, driftwood, treated or painted wood, highly resinous wood, such as
"Old Man's Pine," plastic, plywood, chipboard, garbage, flammable fluids such as
gasoline, naphtha, engine oil, refuse, milk cartons, colored or printed paper. The
combustion of such materials can emit toxic, corrosive, and hazardous fumes that will
pollute the environment.
4.3 Testing Wood Moisture
There are several ways to confirm if the wood is dry enough.
- The wood moisture meter is the best way to check the moisture content of the wood fuel. Split a piece of
wood and then press the metering prongs firmly into the long side of a split piece to test moisture
content. 15-20% percent of moister content is ideal.
- If you purchase firewood, ask for dry seasoned wood and get it checked from your wood merchant.
- Dry wood weighs much less than wet wood.
- Wet wood is hard to light and will emit moisture from the ends while burning.
- Two dry pieces banged together sound hollow, and wet pieces sound solid and dull.
4.4 Recommended Log Sizes & Fire Starters
- A packet of matches or lighter
- A packet of firelighters. We recommend green firelighters made of wood waste
- Seasoned firewood about 300~325mm long in various sizes
o (3.2A) For kindling - 18-20 finely split, dry softwood (total 1.5 kg approximately)
o (3.2B) For intermediate 1 load – 5 pieces (total 1.5 kg, 375 g each approximately)
o (3.2C) For intermediate 2 load – 4 pieces (total 3.0 kg, 750 g each approximately)
o (3.2D) For main load – 3 or more pieces (Total 4.0 kg, 1.3 kg each approximately)
3.2A 3.2B 3.2C 3.2D
Using well-seasoned firewood is key to maintaining and improving the life of the
Hurunui Firebox
