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.
Figure 3.3.1

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.

10
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

11
5.0 Operational Sequence
5.1 Before First Light-up
- Ensure that all the packing material has been removed from the combustion chamber.
- Make sure the St/St baffle and ceramic bricks are installed correctly and the baffle is pushed back.
Please note that the special high-temperature paint used on the heater will go through a curing process; as the
paint heats up, it will firstly soften and can be easily marked; after 2-3 burn cycles, the paint will lightly dull, and
this will indicate that it is now cured and hard. The paint will give off smoke and an odor that can irritate some
people during this process. Please ensure during the curing phase that adequate ventilation is used to open as
many doors and windows as possible to ventilate the area. Once cured, there should be no more smoke or odor.
5.2 Cold Startup
5.2.1 Initial light-up with kindling and intermediate load
1. Slide the air slide control to the "HIGH" position.
2. Stack intermediate load, i.e., 4 x small size logs at the base of the firebox.
3. Stack around 18-20 very small kindling pieces on top of these logs. This is the "Top-Down Start-Up"
method, which considerably reduces particle emission during the start-up phase.
4. Place the firelighters on top of the kindling and light the fire. We recommend green firelighters made of
wood waste.
(1) (2) (3) (4)
5.2.2 Intermediate load 2
5. Keep the door ajar slightly. Use the start-up latch to keep the door ajar in a controlled fashion
6. Close the door approximately after 10 mins making sure that the kindling is well alight. Do not change
the air slide position at this stage.
7. After 15~17 mins, once the small logs are more than 50% burnt, open the door to add a 2nd intermediate
load, i.e., 4 pieces of medium fire logs. Close the door and continue to lite the fire on the "HIGH" air slide
setting.
(5) (6) – 10 mins (7) – 15~17 mins (8) – 40~45 mins
DO NOT LEAVE BURNER UNATTENDED DURING THIS INITIAL LIGHT-UP PERIOD

12
5.2.3 Main load and controlling output
8. Around 40~45 mins, when the intermediate load 2 is burnt more than 50%, open the main fuel loading
door.
9. Add 3 large size logs and close the main fuel loading door.
10. Once the large size logs are fully alight, the burner is ready to adjust the output by operating the air slide.
11. Adjust the air slide to the medium of low position to control the output.
(9) – 40+mins (10) – 50+ mins (11) – 70+ mins
Always open the door in two stages:
1. Unlatch the door and keep it slightly ajar for 15~20 seconds
2. Then open the door fully.
Always switch the air slide knob gently and gradually.
This practice is essential to avoid puffs of smoke coming into the room.
5.2.4 Refueling and Turning down
12. Before opening the door for reloading, ensure that the air slide is on the "HIGH" setting for approx. 5
mins. This will increase the flue temp and reduce the risk of smoke back into the room. Reloading
should be done when there is a good ember bed and minimal flames. Do not reload when the heater still
has a large amount of wood and flames; this is an inefficient operation and can cause smoke to enter the
room.
13. After reloading, keep the air slide to the "HIGH" position till logs are fully alight.
To turn the burner down, allow the wood to be well alight, then turn the slide approx. 50% down, wait for
5 mins, and then fully turn down.
Note: When refueling, make sure the air slide has been moved up to the high setting for approx. 5 mins.

DO NOT EVER USE THE BURNER WITH A CRACKED GLASS
 DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS TO START OR REKINDLE
THE BURNER
 ALWAYS MOVE THE AIR CONTROL TO THE OPEN POSITION (TO THE RIGHT)
EFORE OPENING THE BURNER DOOR
Note – The timing given for various steps of the light-up process may vary slightly depending upon wood log
length. After a couple of burns, the user will be able to judge for themselves.

6.0 Operating Hints for Clean Burning and Best Efficiency
 Always use good quality wood fuel. Refer to section 4.2 for details of wood logs that can be used.
 Add fuel reasonably often. A large fuel load placed on a dying fire can drop combustion temperatures
undesirably. The best time to refuel is when there is a minimal flame in the combustion chamber.
 Avoid large smouldering fires. A small intense fire is more efficient.
 Move the heat control to a "HIGH" setting for a minute before opening the door on a low burning fire. This will
clear away any fumes in the firebox.
 Always open the door SLOWLY, and close and latch it shut securely again as soon as possible after re-
loading.
 When loading fuel, place the pieces of wood in a
Front-to-Back direction to ensure proper air access
and the cleanest possible burning. This will give
you the overall emission and room heating efficiency
that the fire was designed and tested to achieve.
 While loading fuel, take care to avoid damage to the firebricks
or top baffle. Do not throw logs into the fire.
 If smoke wafts into the room from a fully established fire while the door is open, the first check that make-up
air can flow freely into the room to replace the air passing up the flue. Make-up air is the replacement air
used by fire for combustion, which needs to come into the room from external sources (see box below).
 Check that the flue is not obstructed in any way, particularly by the rain cap being too close to the end of
the flue. Check flue is sealed correctly. (See the flue cleaning requirements in the maintenance section 9.2. If
these checks do not uncover the fault, you may need to add an extra length of flue and casings (with bracing, if
necessary) to counteract the down draught effects caused by roof shape, nearby buildings, hills, or trees.
Consult experienced wood fire installer for solutions.
 After a season, adjust the door to eliminate any minor leakage if required.
For the fire to draw correctly, air must be able to enter the room where your Hurunui ULEB
burner is installed. You may have to leave a room door slightly open and perhaps a
window elsewhere in the house if your home is of modern airtight construction. This is
particularly important if an air extraction fan operates somewhere in the house. Leaving the
door open will help spread warmth through the rest of your home.
7.0 Maintenance of The Hurunui ULEB
Further sections will describe the systematic process of regular and periodic maintenance and servicing of
different parts of the firebox and flue. Replace parts only with genuine GLEN DIMPLEX spare components:
7.1 Ash Removal
Ash removal is necessary when the ash level is up to the lower door opening. Before carrying out ash
removal, make sure that the burner is cold and there are no hot embers in the firebox. Simply shovel out any
excess, leaving a 15-20mm bed of ash in the firebox. Place the removed ashes in a non-combustible container
with a tightly fitting lid, and move the container outdoors immediately to a place clear of combustible
materials.
7.2 Cleaning the Glass
A good hot fire will burn away any deposits left from a long slow burn. A dampened newspaper with ash or a
non-caustic oven cleaner can be used to clean the glass.

14
7.3 Cleaning the External & Internal Fire Panels
A soft cloth is sufficient to clean and maintain the finish of the panels, cooktop, and the pedestal foot of the
Hurunui fire. The household detergent may damage painted panels or give bad odors while running the fire.
Under no circumstances should a wet cloth or similar be used in the cleaning process of any
external or internal panel or parts of the fire, as it will erode the painted finish.
7.4 Adjusting the Door Latch
- Open the main fuel loading door
- Remove the grub screw pin from the bush, which is on the inner side of the door, just above the door
spindle.
- This screw stops the full rotation of the handle.
- Wind the door handle in or out depending upon whether you want to loosen or tighten the door seal.
- Sandwich a piece of paper between the firebox edge and the door seal to check the door seal.
- Close the door and try to pull the piece of paper.
- The paper will be jammed or slide with effort when the seal is good or sufficient.
- Carry out this test on all four sides of the door to ensure the seal is even on all sides.
7.5 Door and Door Glass Seals
Door seals of the main door should be checked and, if required, will need replacement periodically depending
upon the usage of the Hurunui burner. Over the period, the door and glass seals will become hard and cause
air to leak into the firebox. This excess air can lead to the 'over-firing' of the burner and damage the burner
parts. If any part of the burner or flue system is glowing, the burner is over-fired.
7.6 Heat Output Control (Air Slide)
If the air slide does not move freely, have an installer inspect the unit and apply a small amount of
heat resistant air slide lubricant available from Glen Dimplex
7.7 Firebox Ceramic Bricks
The ceramic bricks in your Hurunui burner are essential to achieving a clean and efficient burn. These bricks
are likely to degrade with time and will need replacement periodically. The life of the bricks will depend upon
usage, type of fuel burnt, and care taken during operations and maintenance. The bricks are held in place
using the brackets welded to the firebox sides and the rear. Due to the high temperature in the firebox, the
bricks may crack with use, and this is normal. If the bricks crack but remain in place, it will not affect the
performance of the fire and subsequently can continue to be used. The bricks should be replaced only when
they are damaged enough in place and cannot perform their intended task. Refer to Fig in section 3.7 for the
location and sequence of assembly of bricks in the firebox of the Hurunui burner.
7.8 Firebox Baffle
- The stainless steel baffle used in Hurunui ULEB is made of thick gauge stainless steel and, hence, is heavy
to handle. It has a rear air intake chute, which needs to be fitted properly into the slot on the back wall of the
fire. For flue cleaning, this baffle must be removed as described below.
- First, pull forward the front baffle slightly to disengage the rear chute from the slot on the rear wall. Then push it
to one side so that the baffle is off the other side's support. Keep dropping and tilting the other side to dislodge
it entirely from the supports and then manoeuvre the baffle out of the firebox.
- For replacing the baffle, reverse the steps mentioned above.
- Check that the baffle is locked and hard up against the rear wall of the firebox.
7.9 Flue Inspection & Cleaning
The flue system should be checked at least once a year depending upon usage and, if needed, be swept by a
professional chimney sweep. Do not use chemical chimney cleaners. Check the flue sections nearest the
firebox. If a flue system is becoming excessively blocked or needs frequent cleaning, investigate the
installation, fuel, and operation of the burner with the help of a professional.

15
First, remove all the ceramic bricks and the baffle. This will enable to drop and collect all the chimney dirt into
the firebox without removing the main flue pipe. Once the chimney sweep operation is complete, clean the
firebox chamber properly and put back both the front & rear baffle, both the air tubes and the bricks.
8.0 Hurunui Replacement Parts
Some parts of the Hurunui burner are considered consumable. These parts will wear out or degrade over time.
The life of these parts will vary upon
- How frequently fire is used
- Type of fuel. Some species of wood fuel are harsher than others.
Following items are considered as operational consumables:
- Bricks - Set of ceramic bricks for the main combustion chamber or firebox.
- Stainless Steel Baffle
- Front Air Deflector.
- Seals - Main Door Seal and Door Glass Seal
- Door Glass - Main Door Glass
- Door locking mechanism and start-up latch
These consumable parts should be replaced as soon as they show signs of wear. Running your burner with
worn or broken parts may result in reduced output, an increase in fuel consumption, and even damage the
burner's firebox or other vital parts. We highly recommend a frequent visual check of these consumables and
other parts of the burner.
9.0 Common Issues and Problem Solving
1. Blackening of the door glass - Blacking of the glass can be caused due to wood that is not seasoned,
wet, or running the heater on low for long periods. Very resinous wood may also cause this issue. Poor
seals on the door may also be a factor. Ensure only dry seasoned wood is used.
To remove the dirty film, try the following:
a. Burn the fire hot with the full load and air slide on a high setting for 30 minutes.
b. Try to clean glass with damp newspaper and ash when the fire has completely cooled down
c. Try using non-caustic oven cleaner
Caution: Do not scrub using steel products or abrasive material, as it can leave scratch marks on the
glass or damage printing on the glass.
As per the new air plan, it is an offense in the Environment Canterbury region to burn wood with
greater than 25% moisture.
2. Paint discoloration, paint damage - The paint on your heater will dull off over time, and this is a normal
process. Painted surfaces will get scratched, and paint lifting will occur due to vigorous cleaning or the
use of cleaning products.
A soft rag is sufficient to clean and maintain the finish of the panels, cooktop, and the pedestal foot of
the Hurunui fire. The household detergent may damage painted panels or give bad odors while running
the fire. Under no circumstances should a wet cloth or similar be used in the cleaning process of
any external or internal panel or parts of the fire, as it will result in corrosion of the painted
finish.
General dulling of the paint can be resolved with light sanding and a re-spraying using the Stove Bright
P22 metallic spray can.
3. Smoke into the room - Smoke entering the room when the door has been opened can result from
negative pressure in the home. This can occur due to heat transfer kits, extractor fans, well-sealed
homes not allowing the heater to draw combustion air, environmental pressures due to terrain large trees
nearby, and/or pressures caused by roof pitch and staggered roof levels.

16
To prevent this extreme negative pressure, open a window approximately 6mm to allow combustion air to
enter the room. Adding a vent in the ceiling will enable air to enter the room, reducing negative pressure
and can help with air starvation.
4. Performance issues - Several things can influence the lack of performance. The various factors can be
wood with high moisture content (Masport recommends this be between 16-20%), negative room
pressure/air starvation, running the heater on a lower air setting for prolonged periods, blocked flue pipe,
or incorrect wood species.
Using appropriate wood fuel and operating the fire as per sections 5.0 and 6.0 will help tackle the
performance issues. Opening a window or adding a vent in the ceiling will allow air to enter the room,
reducing negative pressure and can help with the air starvation issue.
5. Consumable components - Several components are considered consumable, as mentioned in section 8
of this manual. Please check the warranty for specific details on these. Operational consumables should
be replaced as soon as they show of wear.
6. Rust issues - Rust will only form when there is moisture present; please note that the stove bright paint is
porous and will allow moisture through to the steel underneath it. Masport does not recommend cleaning
your heater with damp/wet clothes or cleaning agents. Only the use of dry lint-free cloth is advised. If rust
does form, please have the unit inspected by your local dealer/installer, and they can best advise how to
remedy this. Heavy rust may indicate a leak, possibly from the installation.
7. Noise induced by the environment - sometimes high winds, terrain, roof pitches, and surrounding trees
can affect the flue system. This can result in adverse conditions creating noise within the heater and on
the flue pipes. Expansion noise in the firebox and flue system is normal, but excessive noise could
indicate a possible fault with the installation.
In most cases, the noise occurs when the fire is not running. Using the start-up latch and keeping the
door slightly ajar in a controlled fashion help eliminate this noise issue. Contact an experienced installer
to check the installation thoroughly if the noise occurs when the fire is running.
