Air Controls
The Nectre MK3 has two air controls for controlling the
fire.
Top air slide:- This allows air to enter the firebox from above
the door where it is then drawn down into the base of the fire
while keeping the glass clean. Pulling the air slide out offers
maximum burn rate, while sliding it in offers minimum burn
rate.
Bottom air slide:- This allows air to enter directly into the base
of the fire and is used as a boost especially when getting the
fire up to temperature.
Secondary air holes in the rear of the firebox provide
additional oxygen for a more complete combustion of the
gases released from the burning wood.
Door Handle
Warning: the 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 air slide before opening the door to eliminate the
chance of backdraft and/or smoke entering the room.
Fan
The fan can be used to spread heat around the room quicker,
as well as distribute heat into other rooms. It does not have to
be on if not required.
A remote control supplied with the heater is used to turn the
fan on and determine the chosen speed.
If the radio frequency used by the remote control interferes
with other frequencies in the home such as wireless internet
or child monitor refer to “8. Change Fan Controller Frequency”
in the Maintenance & Servicing section for details on changing
the frequency.
•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 these fumes have
cleared.
•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 minimise any potential moisture
content.
• For best results, wood should not exceed 350mm in
length and 150mm diameter. Any larger and 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:
o Causes low combustion efficiency
o Produces poor emissions (smoky)
o 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.
• Place firelighters or paper and dry kindling wood in the
base of the firebox.
• Open both air controls :
o Top air slide –pull knob all the way out (to the left)
o Bottom air slide –slide spring handle across to the
left

4. LIGHTING THE FIRE
3. RECOMMENDED FUELS
Top air slide Bottom air slide

• Light the paper or firelighters.
• Once the fire has taken hold add larger pieces of wood.
For optimal burn conditions, place the logs in a front to
back orientation (right angles to the door opening). Too
many logs may smother the fire.
• Once the fire is established, close the bottom air slide
(slide to the right). Leaving this open once the fire has
established can risk over-firing and damaging the
appliance.
• Do not leave fire unattended with bottom air control
open as over-firing may occur.
The heat output of the appliance is controlled by the top air
slide.
Maximum Heat Output
• After establishing the fire and loading it with larger
pieces of wood, leave it running with the top air slide
fully open (pulled to the left).
• 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 fire has established,
particulate emissions will be very low, i.e. no smoke,
which is good.
Low Heat Output
• The heat output of the appliance can be reduced by
closing the air slide which will restrict the oxygen
supplied to the fire and slow down the rate at which the
wood burns.
• This setting will provide the best energy efficiency as the
wood burns for longer. However, if not operated
correctly may result in higher particulate emissions.
• Prior to closing the air slide ensure that the fire is
burning briskly. This may require opening the air slide
fully for 5-10mins before shutting down.
• For the optimum between clean burning, and getting the
best in efficiency, from the fully closed position, open the
top air slide 4-5mm.
The air slide can be adjusted to any position so desired
depending on wanted heat output versus burn time.
Reload with more wood
1) Open air slide 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 than one large piece.
5) Close door with top air slide fully open, and leave for
minimum of 10 minutes to allow the fresh wood to
catch.
6) After 10 or more minutes, the air slide can be adjusted
to the desired heat output setting.
Fuel Quality
Use wood with a moisture content of less than 20%. Logs
should not feel moist or damp, or have moss and 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.
If on the rare occasion the wood is not ideally seasoned, still
retaining some moisture, continue using the top air slide to
determine the heat output and burn rate but also leave the
bottom air slide open 3-4mm. This will allow some extra
oxygen into the base of the fire allowing it to burn hotter
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.
5. RUNNING THE APPLIANCE
6. BURNING TIPS

5
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
For advice on the correction of persistent flue problems
consult your supplier/installer for more detail.
Depending on the type of wood burnt and frequency, the
ashes will need removing every 2 to 6 weeks.
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.
Leave a small amount of ash, approximately 10mm thick, in
the bottom of the firebox. This helps to insulate the base of
the firebox.
If a flue/chimney fire occurs:
• Shut air slide 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.
• 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.
• Check inside of flue prior to each season for any build-
up of creosote (wood tar). To do this:
o First remove the upper and lower baffle plates
(refer to “3. Replacement of Baffle Plates” under
Maintenance & Servicing section).
o 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. If only a fine
black powdery layer then that is normal, but if
built up layers of creosote can be seen, then the
flue needs cleaning.
o Refit the baffle plates if no cleaning is required.
• To clean the flue:
o A flue cleaning brush can be purchased from most
wood heater retail outlets or large hardware
stores.
o The objective is to pull the brush down through
the flue.
o With the baffles 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.
o Grab the end of the rope inside the firebox and
pull the brush through.
o Check the inside of the flue with the mirror
and torch. Repeat if necessary.
o Once clean, remove any excess creosote from
the firebox and replace the baffle plates.
• Alternatively, get a flue cleaning service to do the job
for you (it’s a dirty job).
• Check flue integrity by checking that the 900mm
flue sections have not separated at the joins.

9. CLEANING PAINT WORK & GLASS
10. CLEANING THE FLUE

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, then it can upset
the supply of air to the base of the fire. It can aid the fire by
retaining some ash when cleaning out the firebox.
Glass cracking
Do not over tighten the screws on the stainless steel strips
that hold the glass in the door in place. Otherwise, expansion
of the cast iron door may cause the glass to crack.
The purpose of the firebricks in the appliance is to increase
thermal mass and to guarantee the longevity of the steel
firebox. Over time the firebricks may become cracked and
crumble away. If so, then they should be replaced soon after.
To replace the firebricks:
1) Move any ash away from the base of the bricks.
2) Raise the brick retainer so that the bricks can be
removed.
3) Replace with new bricks, and refit the retainer which
holds the bricks in place.
11
1. Remove the side and rear fire bricks and old brick
retainer before fitting the new one.
2. With the retainer orientated with the arms pointing up
(like a square ‘U’ shape), push one end into the back
corner of the firebox.
3. With the retainer in a diagonal orientation relative to
the firebox, tilt the top slightly forward allowing the
bottom corner to drop into the firebox at thefront.
4. Push the bottom front corner towards the back of the
firebox allowing the top of the arm to enter the firebox.
5. Continue pushing the bottom corner towards rear of
firebox so that retainer sits flat in the firebox.
6. Raise the retainer and re-install the fire bricks.

The Nectre MK3 is fitted with two thick steel baffle
plates which help to retain the heat in the firebox by
lengthening the path of the flame as well as protect the
top plate of the heater.
Over time, the baffle may begin to sag a little due to the
excessive heat. This will not affect the way the fire burns,
however it is recommended that you turn the baffle
over to avoid continued sagging.
Eventually the baffle plate(s) will burn through (5+ years)
and if so will need to be replaced.
To remove the baffle plates:
1) Lower baffle plate (500(w) x 300(d) x 12(h) mm) :-
raise the rear of the baffle plate, slide forward free
from the support lugs, and out through the door
opening.
2) Upper baffle plate (400(w) x 160(d) x 5(h) mm) :-
slide baffle plate forward, free from the support
lugs and out through the door opening.
Repeat steps 1 to 2 in reverse to replace withthe new baffle plates.
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
To replace the door glass:
1) Two stainless steel strips hold the glass in place.
Remove the four M4 size Phillips head screws from the
stainless steel strips.
2) Take out the glass, and check if the grey rope beneath
needs replacing. If so replace this rope as well.
3) Position the new glass on top of the grey rope and re-
fit the stainless steel strips and M4 screws.
4) Take extra care not to over-tighten the screws,
otherwise the glass will crack when the heater gets
hot and the door expands.
5) On occasion, the M4 screws will have deteriorated
from the constant heat in the firebox resulting in them
snapping off when trying to loosen them. In this case, a
new hole can be drilled in the door and tapped using a
3.4mm drill bit, and M4 tap
This task may be easier with the door removed from the
appliance and laid horizontally on a work-bench.
1) Remove any old seal from the door.
2) Clean out the groove in the door that the seal was
bedded in 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 if it has been removed and close.
If the door does not close firmly, then the door latch can be
adjusted.
In the front lower right-hand corner of the door opening,
inside the firebox, is a welded tab which the door latch
secures against when the door is closed. Using a large flat-
end screw driver, place it under the base of the tab and
gently lever it out.
Close the door with the door handle to test for any
improvement. If no improvement, repeat process until door
can be closed firmly.

The ash plate acts to protect the front of the firebox below the
door opening from the hot coal bed and fire.
Over time, this may burn through in which case it should be
replaced to ensure the longevity of the firebox.
Clear ash away from the base of the ash plate. Remove the old
ash plate and replace with a new one. When positioning the
new ash plate, ensure that the front top edge is flush against
the inside edge of the firebox beneath the door opening.
The frequency used by the fan remote control can be changed
if interferences are experienced in the home.
NOTE: Unplug the power lead before proceeding.
Remote Receiver Frequency
The remote control receiver has four tiny switches on the side,
as seen in the photo below. Change the switch setting to
something different than current setting. Remember this
switch setting as it will need to be replicated on the fan
controller.
Remote Receiver Location
To access the remote control receiver, remove the steel box
from underneath the unit.
1) Remove the fan cover screw with an M12 Allen key
2) Remove the steel box screw with an M8 Allen key
3) Remove the steel box lid screws with a Philips headed
screwdriver
Remote Transmitter Batteries
Remove the battery cover and batteries. With a small
screwdriver or equivalent, change the switch setting to be the
same as that on the remote control receiver.
Replace the batteries and cover, plug in the power lead and
test the fan with the different frequency setting. If
interferences are still experienced, repeat the steps with
another switch setting configuration.
