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 range hoods must not be placed in the same room or space, as this can cause appliances to emit smoke into the room.

AIR CONTROLS

• The Nectre Mk1 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 complete combustion of the gases released from the burning wood.

DOOR HANDLE

• Warning: The door handle may get hot if the appliance has been left in a High burn setting for an extended 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.

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 paintwork 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 the 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 in length and 150mm in 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:

• Causes low combustion efficiency
• Produces poor emissions (smoky)
• This results in an 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:
   • a. top air slide – pull the handle out (left)
   • b. bottom air slide – slide spring handle left
3. Light the paper or firelighters.
4. 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.
5. Once the fire is established, close the bottom air slide (slide to the right). Leaving this open once the fire has been established can risk over-firing and damaging the appliance.

Do not leave a fire unattended with the 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 the firebox with fuel.

LOW HEAT OUTPUT

• 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.
• 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.
• Before closing the air slide ensure that the fire is burning briskly. This may require leaving the air slide fully open for 5-10 minutes before shutting down.

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). The top air slide can be adjusted to any position so desired depending on wanted heat output versus burn time.

RELOAD WITH MORE WOOD

1. Open the air slide before opening the 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 the 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 the installation guide for details on flue installation.

Factors affecting the flue draught include:

• Insufficient flue height
• Trees or other buildings nearby cause 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

• Depending on the type of wood burnt and frequency, the ashes will need to be removed 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 controls 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 the flue before 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 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. The latch needs adjustment (refer to “6. Adjusting Door Latch”)
2. The door seal needs replacing (refer to “5. Fitting a New Door Seal”)
3. Baffles need 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

1. Remove bricks and old brick retainer from the firebox.
2. With the retainer oriented 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 the front.
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 the rear of the firebox so that the retainer sits flat in the firebox.
6. Raise the retainer and re-install the fire bricks.

REPLACEMENT OF BAFFLE PLATES

• The Nectre Mk1 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 (495 x 250 x 6 mm) – slide the baffle forward so that it can be lowered at the back. Lower the rear of the baffle plate until the front is clear of support pins, and remove through the door opening.
2. Upper baffle plate (400 x 160 x 5 mm) – remove the upper plate in the same way.
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 screwdriver 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.

ADJUSTING DOOR LATCH

• If the door does not close firmly, the latch can be adjusted.
• The latch is fastened onto the door with two removable washers.
• Use a socket wrench to undo the M12 nut, then remove one of the washers directly beneath the nut. Securely fasten the latch assembly again.
• Close the door with the door handle to test for any improvement. If no improvement, remove second washer.

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 it 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.
