USER INSTRUCTIONS
. INTRODUCTION
Before use of this appliance please read these instructions
fully.
WARNING: ANY MODIFICATION OF THE APPLIANCE
THAT HAS NOT BEEN APPROVED IN WRITING BY
THE TESTING AUTHORITY IS CONSIDERED AS
BREACHING AS/NZS 4013.
WARNING: DO NOT USE FLAMMABLE LIQUIDS OR
AEROSOLS TO START OR REKINDLE THE FIRE.
WARNING: DO NOT USE FLAMMABLE LIQUIDS OR
AEROSOLS IN THE VICINITY OF THIS APPLIANCE
WHEN IT IS OPERATING.
WARNING: DO NOT STORE FUEL WITHIN HEATER
INSTALLATION CLEARANCES.
WARNING: WHEN OPERATING THIS APPLIANCE AS
AN OPEN FIRE USE A FIRE SCREEN.
WARNING: OPEN AIR CONTROL BEFORE OPENING
DOOR.
WARNING: DO NOT BURN WOOD THAT IS PAINTED;
OR IS COATED WITH PLASTIC; OR HAS BEEN
TREATED WITH ANY CHEMICAL.
CAUTION: THIS APPLIANCE SHOULD NOT BE
OPERATED WITH CRACKED GLASS.
CAUTION: THIS APPLIANCE SHOULD BE MAINTAINED
AND OPERATED AT ALL TIMES IN ACCORDANCE WITH
THESE INSTRUCTIONS.
The appliance or flue system should not be modified in any
way without the written approval of the manufacturer.
Extraction fans or rangehoods placed in the same room or
space can cause appliance to emit smoke into the room
unless outside air kit is installed.
.. AIR CONTROLS
The Nectre Form 1 features a single air control system.
This single control modulates the amount of oxygen that
enters the firebox at two points - at the top of the door
glass, as well as directly at the base of the fire controlling
the rate of combustion of the wood. In addition, oxygen is
drawn into the upper firebox through the burn tubes, where
combustion of the gases occurs.
The air control is operated by sliding the round stainless
steel tab located on the bottom left of the door. Sliding the
tab all the way clockwise offers maximum burn rate, while
sliding all the way counter-clockwise offers minimum burn
rate. See below:
.. DOOR HANDLE
Warning: door handle may get hot if appliance has been left
in High burn setting for an extended period of time, in which
case use a protective glove or equivalent to open.
Open the air slide before opening the door to eliminate the
chance of backdraft and/or smoke entering the room.

3
. USING APPLIANCE FOR THE FIRST
TIME
The first few times the appliance is lit, it will give off some
odorous fumes. This is caused by the paint curing.
Do not touch the paint work while it is curing otherwise it
can leave a permanent mark on the appliance.
Once the paint has cured it will not re-occur.
Keep the room well ventilated until fumes have cleared.
. RECOMMENDED FUELS
Burn only seasoned hardwood timber with a moisture
content of less than 20%. Newly cut wood should be
allowed to dry/season for 12 to 18 months before use.
Wood should be stored in an environment protected from
the weather to minimize any potential moisture content.
For best results, wood should not exceed 350mm length
and 150mm diameter. Any larger, and the appliance will not
operate at its optimum. It is better to burn several smaller
pieces of wood than one large single piece.
Poor quality timber:
●Causes low combustion efficiency
●Produces poor emissions (smoky)
●Results in additional buildup of creosote (soot) in
the flue which will then require regular cleaning and
may result in a flue fire.
Do not burn painted, impregnated/treated wood,
manufactured board products or pallet wood.
. LIGHTING THE FIRE
1. Place firelighters and/or paper and dry kindling
wood in the base of the firebox.
2. Fully open the air control located on the bottom left
of the door by sliding it all the way clockwise.
3. Light the paper or firelighters.
4. If necessary, leave the door slightly open as the fire
establishes and the glass warms to avoid the build-
up of condensation.
5. Once the fire has taken hold, add larger pieces of
wood. Too many logs may smother the fire.
6. Close the door.
Do not leave fire unattended while the door is open.
. RUNNING THE APPLIANCE
The heat output of Form 1 is controlled by the air control.
.. HIGH HEAT OUTPUT
After establishing the fire and loading it with larger pieces
of wood, leave it running with the air control fully open (slid
all the way clockwise).
This setting will generate maximum heat output.
Running the appliance with the door open will not produce
maximum heating in the room as it will draw a lot of already
warmed air out of the room.
Do not overload firebox with fuel.
Note that this setting is not the most energy efficient as
some heat is lost up the flue instead of being transferred
into the room. However, once the fire is established,
particulate emissions will be very low in this setting.

4
.. LOW HEAT OUTPUT
The heat output of the appliance can be reduced by
closing the air control (sliding all the way counter-
clockwise) which will restrict the oxygen supplied to the
fire and slow down the rate at which the wood burns.
This setting provides the best energy efficiency as the
wood burns for longer. However, if not operated correctly it
may worsen emissions.
Prior to closing the air control, ensure that the fire is
burning briskly. This may require opening the air control
fully for 5-10mins before shutting down.
For the optimum between clean burning and getting
the best in efficiency, slide the air control to the middle
position.
The air control can be adjusted to any position depending
on desired heat output versus burn time.
.. RELOAD WITH MORE WOOD
1. Open air control before opening door.
2. Rake / break up any existing coals.
3. Load the wood with the length orientated front to
back.
4. Better results will be achieved by loading several
smaller pieces of wood rather than one large piece.
5. Close door with air control fully open, and leave for
minimum of 10 minutes to allow the fresh wood to
catch.
6. After 10 or more minutes, the air control can be
adjusted to the desired heat output setting.
. BURNING TIPS
.. FUEL QUALITY
Use wood with a moisture content of less than 20%. Logs
should not feel moist/damp, or have moss/fungal growths.
Symptoms related to wet wood:
●Difficulty starting and keeping a fire burning well.
●Smoke and only small flames.
●Dirty glass and/or fire bricks.
●Rapid creosote build-up in the flue/chimney.
●Low heat output.
●Short burn times, and blue/grey smoke from the
flue/chimney outlet.
Run appliance at high heat output for a short period each
day to avoid large build-up of tars and creosote within the
appliance and flue.
.. FLUE DRAUGHT
The flue has two main functions:
1. To safely remove smoke, gases and fumes from the
appliance.
2. To provide a sufficient amount of draught (suction)
in the appliance to ensure the fire keeps burning.
Draught is caused by the rising hot air in the flue when the
fire has been lit. The position, height and size of the flue
can affect the performance of the flue draught. Refer to
installation guide for details on flue installation.
Factors affecting the flue draught include:
●Insufficient flue height
●Trees or other buildings nearby causing turbulence
●High and gusty winds
●Outside temperature and weather conditions
●Blocked flue

5
For advice on the correction of persistent flue problems
consult your supplier/installer for more detail.
. ASH REMOVAL
Depending on the type of wood burnt and frequency, the
ashes will need removing every 2 to 6 weeks.
Retaining at least 10mm of ash helps protect the firebox
base, and can make it easier to start the fire next time.
Excess ashes should be removed when necessary, placed
in a non-combustible container with a tightly fitting lid
and moved outdoors immediately to a location clear of
combustible materials.
. FLUE/CHIMNEY FIRE
If a flue/chimney fire occurs:
●Shut air control fully to smother the fire
●Do not use the appliance after a flue fire until an
accredited installer has assessed the cause and
any resultant damage.
. CLEANING PAINTWORK AND GLASS
The appliance, when cool, can be cleaned with a damp
cloth.
Over the years, the black paint will fade and can be
touched up with Stove Bright metallic black paint.
To clean the glass, we recommend using a household
window cleaner or general purpose cleaner with a soft
cloth. Do not use abrasive cleaner or scourer pads.
. CLEANING THE FLUE
Check inside of flue prior to each season for any build-up
of creosote (wood tar). To do this:
1. First remove the baffle (refer to “2. Replacement of
Baffle” under Maintenance & Servicing section).
2. Using a small mirror and torch hold the mirror on
an angle below the flue with the torch shining at it
and look for black creosote build-up. A fine black
powdery layer is normal, but if built up layers of
creosote can be seen, then the flue needs cleaning.
3. Refit the baffle if no cleaning is required.
To clean the flue:
1. A flue cleaning brush can be purchased from most
wood heater retail outlets or large hardware stores.
2. The objective is to pull the brush down through the
flue.
3. With the baffle removed, tie a rope to one end of the
brush, and drop the rope from the top (outside on
top of the roof) down the flue.
4. Grab the end of the rope inside the firebox and pull
the brush through.
5. Check the inside of the flue with the mirror and
torch. Repeat if necessary.
6. Once clean, remove any excess creosote from the
firebox and replace the baffle.
Check flue integrity by checking that the 900mm flue
sections have not separated at the joins.
Alternatively, get a flue cleaning service to do the job for
you (it’s a dirty job).

. TROUBLESHOOTING TIPS
.. GLASS IN DOOR BLACKENING
This can have several possible causes:
●Burning unseasoned wood — if the wood is too wet,
it will cause the glass to blacken.
●Appliance operated at low temperature — after an
overnight burn where the air slide control has been
fully closed, the glass may have blackened. When
the fire is re-stoked and burning on the high heat
setting, the blackened glass should self-clean.
●Problems with the flue — insufficient flue draught
can cause the glass to blacken. If the flue is too
short, not properly insulated, or in a position
that results in a downdraught, then there will be
insufficient flue draught. Contact the installer
should this happen.
.. TROUBLE STARTING THE FIRE
If all ash has been removed from the firebox, it can upset
the supply of air to the base of the fire. When cleaning out
the firebox, retaining some ash can make it easier to start
the fire next time.
.. BURNING TOO QUICKLY
If you find that the heater is burning through wood too
quickly, it could be due to one or a combination of the
below factors:
1. Latch needs adjustment (refer to “5. Adjusting the
Door Latch” on page 9)
2. Door seal needs replacing (refer to “3. Fitting a New
Door Seal” on page 9)
3. Baffle needs replacing (refer to “2. Replacement of
Baffle Plate and Burn Tubes” on page 8)
.. GLASS CRACKING
Do not over tighten the screws on the stainless steel strips
that hold the door glass in place. Otherwise, expansion of
the cast iron door may cause the glass to crack.

MAINTENANCE AND SERVICING
. REPLACEMENT OF VERMICULITE
Vermiculite is a naturally occurring aluminium-magnesium
silicate material that is non-toxic and environmentally
friendly. The purpose of the vermiculite bricks in the
appliance is to promote a higher internal temperature
resulting in a longer burn time and greater efficiency. Over
time the vermiculite may become cracked and crumble
away. If so, then it should be replaced soon after.
To replace the vermiculite lining:
1. Move any ash away from the base of the bricks.
2. Remove the brick retainer and remove the bricks.
Replace the vermiculite bricks into the firebox as shown
in the diagram. Ensure vermiculite bricks are placed in the
order listed 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, and slide towards
the front to tuck behind brick retainers bolted to
sides of firebox.
2. Two medium bricks with two angled edges - one
on either corner of the firebox. Ensure angled cut
meets up neatly with side bricks.
3. One small brick at the rear - this should slot right
into place.
Once bricks are in, fit the retainer over the top to hold them
in place.

. REPLACEMENT OF BAFFLE PLATE
AND BURN TUBES
The 6mm thick steel baffle plate helps to retain the heat in
the firebox by lengthening the path of the flame as well as
protect the top of the firebox.
The stainless steel burn tubes provide pre-heated oxygen
directly above the fire, which ignites to help burn off smoke
and gases that would otherwise go up the flue
Over time, the baffle may begin to sag a little due to the
excessive heat. This will not affect the way the fire burns.
Eventually the baffle and burn tubes may burn through (5+
years) and if so will need to be replaced.
To remove the baffle and burn tubes:
1. Vermiculite bricks must be removed before
the baffle plate can be removed (refer to “1.
Replacement of Vermiculite” on page 7 for how
to remove them).
2. This may be made easier by removing the bolt on
tabs from the sides of the firebox, but this is not
necessary.
3. Undo nut and bolt holding burn tubes in place by
using spanner through air deflector slot at front of
firebox. Refer to diagram below:
4. Carefully pivot burn tubes downwards from the
front edge. The rear tips of the burn tubes pass
through the rear of the firebox - pull burn tubes
forwards slightly to dislodge - this will allow the burn
tubes and baffle to be removed from the firebox.
5. Turn the baffle plate on an angle so that it can be
removed through the door opening. Burn tubes can
be removed in a similar method if being replaced -
otherwise they can be left in the base of the firebox
for the moment.
6. Repeat steps 1-5 in reverse to replace with the new
baffle/burn tubes.

. FITTING A NEW DOOR SEAL
Remove the door from the heater and lay it horizontally on
a work-bench.
1. Remove any old seal from the door.
2. Clean out the groove in the door that held the seal
using a flat-end screw driver or equivalent.
3. Run a thin bead of clear roof and gutter silicone
along the groove.
4. Starting at one end, press the new door seal rope
into the groove on the door.
5. Refit the door and close.
APPLY SILICONE
. FITTING NEW DOOR GLASS
Due to the curvature of the glass, the door seal and door
seal retainers must also be removed from the door in order
to gain access to the glass.
To replace the door glass, remove the door from the heater
and lay it horizontally on a work-bench.
1. Remove door seal from the door.
2. Clean out the groove in the door that held the seal
using a flat-end screw driver or equivalent.
3. Using 2.5mm hex key, remove four M4 screws
holding the door seal retainers to the door.
4. Six small stainless steel tabs hold the glass in place.
Remove the screws from the stainless steel strips
with a 4mm hex key.

10
5. Take out the glass, and the flat grey glass seal rope
beneath it. The glass replacement kit will come with
replacement glass seal and door seal ropes.
FIBREGLASS ROPE
6. Position the new glass on top of the replaced glass
seal rope and re-fit the stainless steel tabs and
screws.
7. Hand-tighten the screws until firm. Take extra care
not to over-tighten the screws, otherwise the glass
will crack when the heater gets hot and the door
expands.
8. Dispose of the old glass in a responsible manner.
9. Re-fit the stainless steel door seal retainers to the
door.
10. Follow steps 3-5 listed in “4. Fitting New Door Glass”
on page 9 to replace the door seal.
. ADJUSTING DOOR LATCH
Over time, the door seal can become compressed,
resulting in a less than adequate seal between the door
and the front face of the firebox. For example, if the wood
burns unusually fast even with the air control set to low, it
may mean that there is an air leak around the door.
In this situation, the door seal does not necessarily need
replacing — adjustment of the door latch can tighten the
seal.
Form 1 has a twin hook latch that fastens at two points
highlghted in the diagram below. These latch points can be
adjusted forwards and backwards as needed.
To adjust the door latch:
1. Using 8mm spanner, hold the M5 hex nut tight.
2. Using 3mm hex key, loosen the M5 shoulder screw.
When loose, the latch point will be able to freely
slide forward and backward.
3. Slide the latch point inwards approximately 1 mm
and retighten the shoulder screw.
4. Do this on both latch points.
5. Close the door and test the tightness of the latch. If
too tight or not tight enough, readjust until adequate
latching pressure is achieved.
If the door is still not latching adequately – replace the door
seal.
