1. OPERATING
1.1. 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 (AND DAMPER WHEN
FITTED) BEFORE OPENING FIRING DOOR.
CAUTION: THIS APPLIANCE SHOULD NOT BE OPERATED WITH
A CRACKED GLASS.
CAUTION: THIS APPLIANCE SHOULD BE MAINTAINED AND
OPERATED AT ALL TIMES IN ACCORDANCE WITH THESE
INSTRUCTIONS.
CAUTION: THE USE OF SOME TYPES OF PRESERVATIVETREATED WOOD AS A FUEL CAN BE HAZARDOUS.
The appliance or flue system should not be modified in any
way without the written approval of the manufacturer.
Extractor fans or cooker hoods must not be placed in the
same room or space as this can cause appliance to emit smoke
into the room.
Our Cleanburn technology promotes greater efficiency
THE OPERATING INSTRUCTIONS IN THIS MANUAL APPLY
TO THE BLAZE B520 AND B820 INSERT WOOD HEATER
MODELS.
THEY HAVE BEEN TESTED FOR EMISSIONS AND
EFFICIENCY AND COMPLY ACCORDING TO AS/NZS
4012:2014 & AS/NZS 4013:2014.

AIR CONTROL
The B520 and B820 models feature a single air control system
designed to introduce oxygen to the base of the fire. The air
control is operated by sliding the handle located to the left
above the door. Slide left to open air control for high burn
rate and right to close for low burn rate.
Secondary air holes in the rear of the firebox provide
additional oxygen for more 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 the high burn setting for an extended period. Use
the supplied door handle extension (see image below) or a
protective glove to open.
Open the air slide before opening the door to eliminate the
chance of backdraft and smoke entering the room.
FAN
The fan can be used to help spread the heat around the room
and other rooms faster. The fan does not have to be on when
the heater is in use, and may be switched on or off at any
time.
A remote control supplied with the heater is used to turn the
fan on and select 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 ‘Changing Fan Controllers’ in the
Maintenance & Servicing section for details on changing the
frequency.
1.2. 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.
1.3. 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 minimise any potential moisture
content.
For best results, wood should not exceed ¾ of the firebox
front to back dimension 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 piece at a time.
Poor quality timber:
o Causes low combustion efficiency.
o Produces poor emissions (smoky).
o Results 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.
1.4. LIGHTING THE FIRE
1) Place firelighters or paper and dry kindling wood in the
base of the firebox.
2) Open air control.
3) Light the paper or firelighters.
4) If necessary, leave the door slightly open as the fire
establishes and the glass warms to avoid a build-up of
condensation.
5) 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.
6) Once the fire is established, close the door.
Do not leave the appliance unattended while the door is
open.
1.5. RUNNING THE APPLIANCE
Maximum Heat Output
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 (clean burning).
After establishing the fire and loading it with larger pieces
of wood, leave it running with the air slide fully open to
generate maximum heat output.
3
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.
To further maximise heat output, turn the fan onto high
setting to help spread the heat around the room.
Low Heat Output
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.
The heat output on 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.
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
air slide 4-5mm.
The air slide can be adjusted to any position so desired
depending on wanted heat output versus burn time.
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 the air slide before opening the door.
2) Rake / break up any existing coals.
3) Load wood with the length orientated front to back.
Better results will be achieved by loading several smaller
pieces of wood rather than one large piece.
4) Close the door with the air slide fully open, and leave for
a minimum of 10 minutes to allow the fresh wood to
catch.
5) After 10 or more minutes, the air slide can be adjusted to
the desired heat output setting.
1.6. BURNING TIPS
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 of burning 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 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.
1.7. ASH REMOVAL
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.
