   • The appliance or flue system should not be modified in any way without the written approval of the manufacturer. Extraction fans or rangehoods must not be placed in the same room or space, as this can cause appliance to emit smoke into the room.

WARNING : KEEP BATTERIES OUT OF REACH OF CHILDREN

1. Swallowing may lead to serious injury in as little as 2 hours or death, due to chemical burns and potential perforation of the oesophagus.
2. If you suspect your child has swallowed or inserted a button battery immediately call the 24-hour Poisons Information Centre on 13 11 26 (in Australia) or 0800 764 766 (in New Zealand) for fast, expert advice.
3. Examine devices and make sure the battery compartment is correctly secured, e.g. that the screw or other mechanical fastener is tightened. Do not use if the compartment is not secure.
4. Dispose of used button batteries immediately and safely. Flat batteries can still be dangerous.

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.
• 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 : 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 top air slide before opening the door to eliminate the chance of backdraft and/or smoke entering the room.
WOOD STORAGE COMPARTMENT
Warning : the Nectre Mk3 features a storage area for a small amount of firewood. Do not overload this compartment – ensure that there is at least a 40mm gap to the ceiling of the unit, and no combustible fuel forward of the storage area.
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. Plug the lead from the unit into a power-point. A remote control supplied with the heater is used to turn the fan on, determine the fan speed, and to set a timer. The fan speed of the heater can be controlled with the Low/Med/Hi buttons.

• A timer function allows the fan to be switched off after a set period of time – 1/2/4/8 hours.
• Select the desired time period with the lower buttons on the remote. The heater will beep in response to the amount of time selected – 1 beep for 1 hour, 2 beeps for 2 hours, etc.
• To cancel the timer, press the central “Cancel Timer” button. The heater will emit a long beep.
• To switch the fan off, press the Off button.

USING APPLIANCE FOR THE FIRST TIME

1. The power cable for the Nectre Mk3 may be bundled in the rear of the unit for transportation. Ensure that the cable is pulled clear from the heater before lighting.
2. The first few times the appliance is lit, it will give off some odorous fumes. This is caused by the paint curing.
3. Do not touch the paint work while it is curing otherwise it can leave a permanent mark on the appliance.
4. Once the paint has cured it will not re-occur.
5. Keep the room well ventilated until fumes have cleared.

RECOMMENDED FUELS

1. 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.
2. Wood should be stored in an environment protected from the weather to minimize any potential moisture content.
3. 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. Open both air controls:
3. top air slide – pull handle all the way out (left)
4. bottom air slide – slide spring handle left
5. Light the paper or firelighters.
6. 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.
7. 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.

RUNNING THE APPLIANCE

The heat output of the appliance is controlled by the top air slide.

HIGH HEAT OUTPUT

• After establishing the fire and loading it with larger pieces of wood, leave it running with the top air slide fully open.
• 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.
• Similarly, running the stove with the top air slide and the bottom air slide fully open will often not give the hottest fire as too much heat is lost up the flue and does not come into the room.
• 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. Do not overload firebox with fuel.

LOW HEAT OUTPUT

1. The heat output of the appliance can be reduced by closing the top air slide (slide to the right) which will restrict the oxygen supplied to the fire thereby slowing down the rate at which the wood burns.
2. 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.
3. Prior to closing the air slide ensure that the fire is burning briskly. This may require leaving the air slide fully open for 5-10 mins before shutting down.
4. For the optimum between clean burning, and getting the best in efficiency from the heater, from the fully closed position, open the top air slide 4-5mm (bottom air slide is shut).
5. The top air slide can be adjusted to any position so desired depending on wanted heat output versus burn time.
6. Fan may be turned to low speed setting or off if the heater is putting out sufficient heat without the fan on.

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 rather 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 top air slide 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

For advice on the correction of persistent flue problems consult your supplier/installer for more detail.

ASH REMOVAL

1. Depending on the type of wood burnt and frequency, the ashes will need removing every 2 to 6 weeks.
2. Retaining at least 10mm of ash helps protect the firebox base, and can make it easier to start the fire next time.
3. 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 heater, 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 upper and lower baffle plates (refer to “3. Replacement of Baffle Plates”).
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 baffles 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 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 “6. Adjusting Door Latch”)
2. Door seal needs replacing (refer to “5. Fitting a New Door Seal”)
3. Baffles needs replacing (refer to”3. Replacement of Baffle Plates”)

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 FIRE BRICKS
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, they should be replaced.
To replace the firebricks:

1. Move any ash away from the bricks.
2. Raise the brick retainer and remove bricks.
3. Replace with new bricks, and refit the retainer which holds the bricks in place. REPLACEMENT OF BRICK RETAINER
4. Remove bricks and old brick retainer from firebox.
5. With the retainer oriented with the arms pointing up (like a square ‘U’ shape), push one end into the back corner of the firebox.
6. 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 the front.
7. Push bottom front corner towards the back of the firebox allowing the top of the arm to enter firebox.
8. Continue pushing the bottom corner towards rear of firebox so that retainer sits flat in the firebox.
9. Raise the retainer and re-install the fire bricks.

REPLACEMENT OF BAFFLE PLATES

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 firebox top. 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 x 300 x 12 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 x 160 x 5 mm) – slide baffle plate forward, free from the support lugs and out through the door opening.
3. Repeat steps 1 to 2 in reverse to replace with the new baffle plates.

FITTING NEW DOOR GLASS

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 screws from the stainless steel strips with a 3mm hex key.
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 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. Dispose of the old glass in a responsible manner.

FITTING A NEW DOOR SEAL
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 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 if it has been removed and close. APPLY SILICONE

ADJUSTING DOOR LATCH

If the door does not close firmly, the latch can be adjusted. The latch is fastened onto the door with two removeable washers. Use a socket wrench to undo the M12 nut, then remove one of the washers directly beneath the nut. Securely fasten latch assembly again.

REPLACEMENT OF ASH PLATE
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.

RECEIVER REPLACEMENT
Over the life of the heater, the fan receiver may fail. If this occurs, it will need to be replaced. Unplug the power lead before proceeding. To access the remote control receiver, remove the steel box from underneath the unit.

1. Remove the fan cover. The M12 button screw securing this can be removed with an 8mm hex key.
2. Remove the receiver mount screw (M8) with a 5mm hex key. Receiver can then be pivoted forwards and carefully removed from heater.
3. Unplug and swap fan receiver with replacement receiver.
4. Reinstall the new receiver by repeating steps 1 and 2 in reverse.

FAN REPLACEMENT

Unplug the power lead before proceeding. To change/remove the fan assembly from underneath the unit.

1. Remove the fan cover. The M12 button screw securing this can be removed with an 8mm hex key.
2. Lift the fan assembly over the shelf lip.
3. Disconnect the fan from the power cable, and remove fan from heater.
4. Remove the fan component from its housing by removing four Philips head screws from rear of housing. Replace fan, and reinstall into heater by following Steps 1-3 in reverse order.
