1.2. GENERAL OPERATION
1.2.1.DAMPER
The damper is a critical component of the fireplace and should
be treated as such. With the damper open, smoke is able to
escape the fireplace and into the flue, with it closed it will
prevent cold air from entering the room while the fireplace is
inactive.
IT IS VITAL THAT THE DAMPER IS OPEN DURING OPERATION
OF THE FIREPLACE. PLEASE CHECK BEFORE EVERY USE.
A damper handle for opening and closing the damper is
provided with the fireplace
Refer to operating instructions below, along with diagrams to
open and close the damper.
1. To open the damper, use the tool to push in the
adjustment cog and turn to the left until you feel it
lock into place.
2. To close the damper, push the adjustment cog in and
turn to the right until it locks into place.
3. Visually inspect the orientation of the damper by
looking up into the ceiling of the fireplace, to ensure
it is correctly oriented. Vertical is open, horizontal is
closed.
CROSS SECTION SIDE VIEW OF DAMPER OPERATION

1.2.2.SPARK ARRESTOR
The spark arrestor is designed to prevent any sparks or small
debris from escaping the fireplace. It should always be in place
when the fireplace is in operation, especially when
unattended.
To open the spark arrestor, pull the right side towards you and
it will swing open to the left. To close, push closed until the
magnetic stop seats against the spark arrestor.
WHEN IN OPERATION SPARK ARRESTOR WILL BE HOT, USE
DAMPER TOOL OR HEAT RESISTANT GLOVES TO OPEN.
1.2.3.ASH TRAY
The ash tray will catch ash as it falls through the grate, making
cleaning of the fireplace a much simpler task. To remove
simply pull the ash tray out towards you and slide back in until
fully seated once finished cleaning.
THE ASH TRAY WILL BE HOT DURING OPERATION. USE HEAT
RESISTANT GLOVES IF IT IS NECESSARY TO REMOVE.
1.2.4. FAN
The N900 Open Fireplace is fitted with an electric fan to
further enhance it’s heating performance.
To operate, ensure the fan is plugged in (built-in installations
will be plugged in during install) and use the supplied remote
control to select the setting you wish.
The fan has 4 settings: off, low, med and high. Once in
operation, to switch between settings press the desired fan
output and the fan will slow down momentarily before
switching to the new speed.
1.3. USING THE APPLIANCE FOR THE FIRST TIME
For the first few times the appliance is lit, odorous fumes
will be given off as the paint cures.
Do not touch the paint work while it is curing otherwise it
can leave a permanent mark on the appliance.
Keep the room well ventilated until these fumes have
cleared.
Once the paint has cured, this will not re-occur.
1.4. RECOMMENDED FUELS
Burn only seasoned hardwood timber with a moisture
content of less than 20%.
Newly cut wood should be split and 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, it is better to burn several smaller pieces
of wood than one large piece at a time.
Poor quality timber:
oCauses low combustion efficiency.
oProduces poor emissions (smoky).
oResults in additional build-up 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.
1.5. LIGHTING THE FIRE
1) Open the damper and visually inspect to ensure it is open.
2) Place firelighters or paper and dry kindling wood on the
grate of the fireplace
3) Light the paper or firelighters.
4) If necessary, leave the spark arrestor open as the fire
establishes.
5) Once the fire has taken hold add larger pieces of wood.
Too many logs may smother the fire.
6) Once the fire is established, close the spark arrestor.
7) Keeping the fire burning at the rear of the firebox will
minimise the chance of any smoke spillage into the room.
DO NOT LEAVE THE APPLIANCE UNATTENDED WHILE THE
SPARK ARRESTOR IS OPEN.

4
1.6. RUNNING THE APPLIANCE
RELOAD WITH MORE WOOD
1) Open the spark arrestor.
2) Rake / break up any existing coals.
3) Load wood on top of the glowing coals. Better results will
be achieved by loading several smaller pieces of wood
rather than one large piece.
4) Leave the spark arrestor open for 2 minutes to allow the
wood to catch fire. Once lit, close the spark arrestor.
DO NOT OVERLOAD FIREPLACE WITH FUEL
1.7. BURNING TIPS
FUEL QUALITY
Use wood with a moisture content of less than 20%. Logs
should not feel moist or have moss and fungal growths.
Symptoms of burning wet wood:
Difficulty starting and keeping a fire burning well
Smoke and only small flames
Dirty 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
FLUE DRAUGHT
The flue has two main functions:
1) To safely remove smoke, gases and fumes from the
appliance.
2) To provide sufficient 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.
1.8. ASH REMOVAL
ONLY REMOVE ASH TRAY WHILE FIREPLACE IS INACTIVE.
Excess ashes should be removed when necessary, placed in a
non-combustible container and moved outdoors immediately
to a location clear of combustible materials.
To remove ashtray, use handle cut-out in the ashtray to pull
up and towards you from underneath the grate lip.
CROSS SECTION SIDE VIEW
1.9. FLUE FIRE
To prevent flue fires it is recommended that your flue is
professionally cleaned once per season at a minimum, subject
to the quality of fuel used.

5
If a flue fire occurs:
Shut the spark arrestor to prevent any falling debris from
spilling out of the fireplace.
Contact emergency services if flue fire worsens.
Do not use the appliance after a flue fire until an
accredited installer has assessed the cause and any
resultant damage.
1.10. CLEANING PAINT WORK
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.
DO NOT USE ABRASIVE CLEANER OR SCOURING PADS.
1.11. CLEANING THE FLUE
Check inside of flue prior to each season for any build-up of
creosote (wood tar).
TO CHECK THE FLUE:
1) Hold a small mirror on an angle below the flue, with a
torch shining towards it, and look for black creosote
build-up. It is normal to see a fine black powdery layer,
but if built up layers of creosote can be seen, the flue
requires cleaning.
TO CLEAN THE FLUE:
1) Remove the damper (refer to ‘Replacing the Damper
Plate’ under Maintenance & Servicing).
2) A flue cleaning brush can be purchased from most wood
heater retail outlets or large hardware stores.
Alternatively, hire a flue cleaning service to do the job for
you (it’s a dirty job).
3) With the damper removed, tie a rope to one end of the
brush, and drop the rope down the flue (from outside on
top of the roof).
4) Grab the end of the rope from inside the firebox and pull
the brush down through the flue.
5) Check the inside of the flue with the mirror and torch.
6) Repeat cleaning process if necessary.
7) Once the flue is clean, remove any excess creosote from
the fireplace.
8) Refit the damper plate.
ONLY PULL BRUSH DOWNWARDS THROUGH FLUE, AS
PULLING UPWARDS MAY SEPARATE THE FLUE SECTIONS AT
THEIR JOINS.
1.12. TROUBLESHOOTING TIPS
TROUBLE STARTING THE FIRE
Ash build up in the ashtray can obstruct the slots in the grate
and inhibit the fireplace’s ability to draw air through the grate
and will make a fire hard to start and/or maintain.
When cleaning, it is best to ensure that the grates are clean,
free from any obstructions and the ashtray completely empty.
2. MAINTENANCE AND SERVICING
2.1. REPLACING THE FIRE BRICKS
The fireplace needs fire bricks to increase the thermal mass
and guarantee the longevity of the steel firebox. Over time
the firebricks may become cracked and crumble away. At this
point they should be replaced.
To replace the firebricks:
1) Lift and remove the two halves of the grate.
2) Angle bottom edge of firebrick resting on shelf towards
you and remove from brick retainer.
3) Replace with new bricks by angling brick forward and
under the brick retainer, allowing bottom edge of brick to
rest on lower shelf.
4) Reinstall the two halves of grate.

6
2.2. REPLACING DAMPER COMPONENTS
The damper plays a critical role in the safe and efficient
operation of the open fireplace. It allows smoke to escape the
fireplace during operation and keeps warmth in the house
when the fireplace is not in use.
Over time the damper plate may begin to warp, this is normal
and will not affect its function. After years of use it may
eventually burn through, requiring it to be replaced.
ONLY REMOVE DAMPER WHILE FIREPLACE IS INACTIVE.
TO REMOVE THE DAMPER PLATE:
1) Remove any excess ash and coals.
2) Orient the damper in its open position.
3) Reach up into the opening of the flue to locate the
damper plate, finding the 2 bolts and 2 nuts holding the
damper plate to the damper rod. Remove these using a
10mm socket and 10mm spanner.
4) Remove the damper plate and replace with new one.
TO REMOVE THE DAMPER ROD:
If the damper rod requires replacing as well follow these
steps:
1) Remove damper plate first.
2) Located on the front of the damper rod is a cog to adjust
the damper. There is an M4 hex head grub screw holding
this in place. Using an M4 hex allen key, remove the grub
screw.
3) The cog, two washers and spring will slide off the end of
the damper rod. Remove and retain these.
4) The damper rod will now be free to slide backwards and
angled down into the fireplace for removal.
5) Replace any components needing replacement and refit
damper by reversing the steps.
6) Visually and physically inspect the re-installation of the
damper rod and plate to ensure correct operation.

2.3. ADJUSTING THE SPARK ARRESTOR
The spark arrestor is designed with the ability to be flipped, to
reverse which way it opens.
ONLY ADJUST THE SPARK ARRESTOR WHILE THE FIREPLACE IS
INACTIVE.
TO FLIP THE ORIENTATION OF THE SPARK ARRESTOR:
1) Lift spark arrestor up until the bottom of the hinge rod
becomes free of its locating hole.
2) Angle bottom edge out and remove the top end of the
hinge rod from its locating hole. Pull down to remove.
3) Remove spark arrestor stop from its locating hole by
pulling upwards.

4) Flip spark arrestor so that hinge rod is on the right side
and re-install by repeating steps 2 and 1.
5) Place spark arrestor stop in its locating hole on the
opposite side.
2.4. REPLACING THE FAN
The fan installed in the N900 Open Fireplace is rated to high
temperatures, but after years of use it may be necessary to
replace the fan or its associated receiver.
ONLY REPLACE THE FAN WHILE THE FIREPLACE IS INACTIVE.
TO REPLACE THE FAN AND/OR RECEIVER
1) Remove the two halves of the grate.
2) Remove the firebricks.
3) Using an M8 hex allen key or hex head socket,
remove the 4 bolts holding the firebox door in place.
It may be necessary to apply WD-40 or equivalent
penetrating oil to loosen the threads.
(If the bolts don’t want to budge or the head has
been rounded out, don’t stress. Drill out or grind the
head off the bolt. The door can still be removed and
the bolt and nut will be replaced anyway.)
4) Pull the top end of the firebox door towards you and
the door should slide up and out.
5) Remove and replace the 4 U-fasteners which hold
the door bolts.
