DO NOT OVER FIRE THIS
HEATER. Attempts to
achieve heat output rates
that exceed heater design
specifi cations can result in
permanent damage to the
heater and to the catalytic
combustor. Over fi ring the
appliance may cause a house
fi re. Never burn the appliance
so hot that the appliance or
chimney connector begins to
glow.
Do not use a grate or other
device to elevate the fi re off of
the fi rebox fl oor. Burn the fi re
directly on the bricks.
Ashes should be placed in a
steel container with a tightly
fi tting lid and moved outdoors
immediately. If the ashes are
disposed of by burial in soil or
otherwise locally dispersed,
they should be retained in
the closed container until
all cinders have thoroughly
cooled. Other waste shall not
be placed in this container.
It is required in some jurisdictions to install smoke and carbon monoxide detectors where
heaters are installed. Install at least one smoke detector on each fl oor of your home to
ensure your safety. It should be located away from the wood appliance and close to the
sleeping areas. Locating a smoke detector too close to a wood appliance can cause the
smoke detector alarm to sound if a puff of smoke is emitted while the wood appliance door
is open during reloading. Follow the smoke detector manufacturers placement, installation,
and maintenance instructions.

COMBUSTION AIR
Ensure adequate combustion air allowing for all other exhausting type appliances in the dwelling (range hoods,
dryers, etc.). In air tight homes and modern constructions, careful considerations must be taken into account
when using a wood burning appliance. Heat recovery ventilators (HRV) systems along with constant running
fan motors in air handlers must be taken into account when balancing the system. Failure to do so may
result in air starvation, smoke spillage and carbon monoxide threats. Consult a HVAC specialist for proper
installation. Ensure adequate combustion air allowing for all other exhausting type appliances in the dwelling
(range hoods, dryers, etc.). In airtight houses it is recommended to install a fresh air inlet into the room where
the appliance is located, to prevent air starvation.
DRAFTING PERFORMANCE
Draft is the force which moves air into the appliance up through the chimney. The amount of draft created by
your chimney depends upon length, off sets, insulating properties, obstructions (such as architectural design,
trees), local geography and other factors.
External forces, such as outdoor temperature, wind, barometric pressure, topography, or factors inside the
home (negative pressure from exhaust fans, chimneys, air infi ltration, etc) may adversely aff ect draft.
Too much draft may cause excessive temperatures in the appliance and may damage the heater. An
uncontrollable burn or excessive temperature indicates excessive draft.
Inadequate draft may cause back puffi ng (spillage) into the room and plugging of the chimney, chimney cap or
spark arrestor screen. Inadequate draft may cause smoke to leak into the room through appliance or chimney
connector joints. Poor draft can also lead to poor heat production and the inability for the combustor to remain
active in lower burn rate settings.
High effi ciency appliances, such as your Blaze King stove, may require some fi ne tuning of your chimney
system in order to maximize performance.
Blaze King cannot be responsible for external forces leading to less than optimal performance.
ROLE OF THE CHIMNEY
Without a proper installed chimney, this appliance will not burn correctly.
The role of the chimney is to pull the proper amount of air into the fi rebox for the purpose of complete
combustion. Incomplete combustion will lead to more smoke and pollution of the outside air. A proper
operating chimney will allow the user to enjoy peak performance at all burn operating levels from low to high.
Blaze King therefore recommends vertical installations with a minimum length of 15’ from appliance top to
chimney cap. In insert applications Blaze King recommends insulated liners into all existing chimneys.

INSPECT CHIMNEY
Before connecting any wood-burning unit to an existing chimney, inspect the chimney to be sure that it is in
good condition. There must be no cracks or holes. The cross-sectional area can diff er from the fl ue collar as
long as suffi cient draw is maintained and local codes and jurisdiction are observed.. A proper chimney is crucial
for safe, satisfactory operation of any wood heating system. Relining or rebuilding may be necessary to make
the chimney safe, effi cient, and in conformity with local codes.
Masonry Chimneys that have a very large cross-section , particularly exterior chimneys, may experience poor
draft and may require relining to reduce the cross-section-and provide a proper draft. This is also an ideal time
to clean the existing chimney. For peak effi ciency, a clean chimney fl ue is essential. A qualifi ed professional
chimney sweep can perform both inspection and cleaning. If you choose to clean your own chimney use the
proper tools. Homemade cleaners may damage your chimney.

GENERAL CHIMNEY INSTALLATION
If this stove and its chimney components are not properly installed, a house fi re may result. For your safety,
follow the installation directions. Contact local building or fi re offi cials about restrictions and installation
requirements in your area.
We recommend that the inside your chimney be at least the same diameter as the fl ue of your stove. If you
plan to use an existing masonry chimney, be sure it is free of cracks and loose joints. Gases traveling through
a chimney can reach extremely high temperatures. Cracks or loose mortar can allow hot gases to reach the
wood portion of the structure surrounding the chimney. These toxic gases can also re-enter the house through
cracks and small holes in the chimney, or cause back-puffi ng which will result in excessive smoking. Be on
the safe side and have your chimney inspected by a certifi ed chimney sweep. A 6 inch insulated stainless
steel chimney liner with a direct connection to the stove is recommended for masonry chimney installations. A
chimney must extend at least three feet above the highest point where it passes through the roof and at least
two feet higher than any portion of the building within ten feet of the chimney. Smoke travels up the chimney
in a circular, spiraling motion. A 6 inch round insulated stainless steel liner allows the smoke to travel with less
resistance. A rough masonry chimney without a good smooth liner can result in the rapid build up creosote.
• BEFORE YOU BEGIN CHECK ALL LOCAL CODES AND REGULATIONS REGARDING
YOUR INSTALLATION.
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE

YOUR FIRST FIRE!
The following pages contain information on the major components and operation of your heater. Please
take time to read about them as it will give you a better understanding of how your appliance works. This
understanding will help you to operate your appliance properly thus will extend the life of your appliance and
allow you to get the highest effi ciencies from your heater.
THERMOSTAT
The thermostat knob is located on the lower left side of the front cast assembly. It controls the burn rate of the
stove. Any thermostat position between LOW(thin line) and HIGH(wide line) will produce the desired clean
burning characteristics. However, since each installation is diff erent, you may fi nd it necessary to operate
the thermostat to suit your situation. A HIGH(wide line) thermostat setting will produce maximum heat which
is more than suitable for heating the average size home. All adjustments to the thermostat should be done
gradually. When you fi rst light the stove set the thermostat to HIGH(wide line) setting for 20-30 minutes, or
until the fi re is well established. Once the fi re is
established turn the thermostat to MED(middle
of line) for 5 minutes and then to a LOW(thin
line) setting or the desired setting. Too rapid
an adjustment may cause the stove to operate
improperly. The most common mistake new
owners make is continually adjusting the
thermostat.
OPERATING INSTRUCTIONS
Page 21
BYPASS
Most catalytic wood burning appliances have a bypass device to allow the smoke from the fi re to temporarily
bypass, or go around, the catalytic combustor. The bypass door is located inside the fi rebox at the top of
the stove. The bypass is a steel plate door, and is controlled by the bypass rod and latch above the door in
the middle of the stove. Use the bypass handle on the side of the latch (Fig. 10) to pull the rod out, then the
bypass is open, use the bypass handle on the center of the latch to push the rod in, then the bypass is closed
(Fig. 11). The bypass handle is hung from a bracket on either the left or right side of the shroud.
NEVER OPEN THE LOADING DOOR WITHOUT OPENING THE BYPASS DOOR
DO NOT TOUCH THE BYPASS LATCH DIRECTLY, ALWAYS USE THE BYPASS HANDLE. DURING
OPERATION THE BYPASS LATCH GETS VERY HOT AND CAN CAUSE SERIOUS BURNS.

CATALYTIC THERMOMETER
The catalytic thermometer is located in the lower left-hand corner
of the cast surround. (Fig. 12) It’s purpose is to show you if the
combustor is active. Always operate the stove when the needle is in
the active red zone. When the combustor is not active the stove will
emit smoke and will not be effi cient. For an accurate reading, turn
fans off for approximately 10 minutes and then read the thermometer.
SELECTING WOOD
• THIS APPLIANCE IS DESIGNED TO BURN NATURAL WOOD ONLY. DO NOT BURN TREATED
WOOD, COAL, CHARCOAL, COLORED PAPER, CARDBOARD, SOLVENTS OR GARBAGE.
• HIGHER EFFICIENCIES AND LOWER EMISSIONS WILL GENERALLY RESULT WHEN BURNING
AIR DRIED SEASONED WOODS, AS COMPARED TO WET, GREEN OR FRESHLY CUT WOODS.
• BURNING WET UNSEASONED WOOD CAN CAUSE EXCESSIVE CREOSOTE ACCUMULATION.
WHEN IGNITED IT CAN CAUSE A CHIMNEY FIRE THAT MAY RESULT IN A SERIOUS HOUSE FIRE.
OPERATING INSTRUCTIONS
AF25
Use dry seasoned wood, split and stacked and protected from rain for at least 24 months with a moisture
content of 20% or lower. It takes a great deal of energy to evaporate the moisture contained in green wood
and that energy will not be heating your house. Also, green or wet wood will greatly increase creosote
problems. The only accurate method to determine moisture content in wood is to use a moisture meter.
Never burn salt-water driftwood. It is very corrosive and will damage the fi rebox. Burning salty wood also
voids the warranty.
This controlled combustion fi rebox has been designed for high effi ciency and long burn times.
The proper time to add more wood is when the last charge has been reduced to a glowing charcoal bed
and while the catalytic thermometer is still active range. There will be very little smoke at this stage in the
burn cycle.
Both hardwood and softwood burn equally well in this appliance but hardwood, which is more dense, will weigh
more per cord and burn a little slower and longer. Firewood should be split and stacked in a manner that air
can get to all parts of it and covered in early spring to be ready for burning that fall.
The only accurate way to determine wood moisture is to purchase a moisture meter.
• NEVER START A FIRE UNLESS ALL BRICKS ARE CORRECTLY PLACED INSIDE THE FIREBOX.
CHECK THE INSTALLATION INSTRUCTIONS CAREFULLY.
• ALWAYS OPEN THE BYPASS DOOR BEFORE OPENING THE LOADING DOOR.
• ONCE THE LOADING DOOR IS CLOSED, CLOSE THE BYPASS DOOR DIRECTLY AFTER THE
CATALYTIC THERMOMETER NEEDLE IS IN THE ACTIVE ZONE.

HOW TO USE MOISTURE METERS
1. Take a random selection of around 3-4 logs per
cubic yard or cubic meter.
2. Split each log down the middle.
3. In the center of log push pins of meter along
grain - three measurements are taken on the
freshly split surface: 2” or 5 cm in from each
end of the log and in the middle of the split
surface with suffi cient contact (see fi gure).
4. Do this to all the logs and take an average of
the readings (this will be only an approximate
indication but a good guide).

EFFICIENCY
Effi ciency was determined using the method outlined in B415.1-10 test method. It is represented by the Higher
Heating Value (HHV) as the fuel used during testing contains between 19% - 25% water moisture included in
the total calculated fuel weight. (Other test methods such as LHV or Low Heating Value, do not take the water
moisture into account).
Annual Fuel Utilization Effi ciency (AFUE) attempts to represent the actual, season long, average effi ciency of
an appliance. HHV is the actual, calculated average effi ciency obtained under test conditions. Using correctly
seasoned wood is important when trying to gain effi ciency. The more seasoned (dry) the wood, the higher the
effi ciency (less energy wasted on eliminating moisture during combustion). Operating your Blaze King at lower
settings will result in higher effi ciencies as the fuel will undergo a more complete combustion.

LIGHTING THE FIRE
NOTE: As you heat up the stove for the fi rst time, the paint will go through a curing process and will give off an odor. To
minimize the inconvenience, burn the stove at a low temperature setting for several hours. It is advisable to open a door
or window until the odor dissipates. You may also notice a change in color as the paint cures, this is normal and will
appear uniform after subsequent fi rings.
1. DO NOT USE A GRATE. BUILD THE FIRE DIRECTLY ON THE BRICK IN THE BOTTOM OF THE APPLIANCE.
2. Set the thermostat to HIGH (maximum) position and turn the fan OFF.
3. Open BOTH the loading door and the bypass door (bypass latch / rod pulled out using bypass handle).
4. Place 10-20 balls of non-glossy paper on the fl oor of the fi rebox, or use a Blaze King fi re starter puck, and then
stack 8-10 lbs of kindling on top of the paper in a crisscross fashion. Be sure to space out the kindling to allow air
to fl ow throughout the fi rebox.
5. Light the balls of paper, or starter puck, and leave the loading door cracked at least 2” to allow the kindling to fully
ignite. This should take approximately 5 minutes. DO NOT LEAVE THE APPLIANCE UNATTENDED.
6. Once the kindling load is fully engulfed, latch the loading door shut BUT keep the bypass door open in order
to get the catalytic combustor up to operating temperature. This is signifi ed by the needle on the catalytic
thermometer moving towards the red “active” zone. This should take no longer than 10 minutes.
7. After 10 minutes and/or once the needle on the catalytic thermometer is in the red “active” zone, close the bypass
door (push the bypass latch / rod in using the bypass handle). LEAVE THE THERMOSTAT ON HIGH.
8. Let the kindling load burn down to small chunks of wood in order to build a 2-3” thick coal bed. This should take
15-25 minutes of continuous burning on HIGH.
9. While waiting for the kindling load to burn down, PREP YOUR MAIN FIREWOOD LOAD. The ideal wood load
for this unit consists of: 3-4 pieces cut to 16” for the bottom row (to be placed into the unit in a front to back
orientation) and 1-2 pieces cut to 18-20” for the top row (to be placed into the unit in a side to side orientation).
The main load should weigh 20lb – 40lb (will vary based on wood species used).
10. Once satisfi ed that a suitable coal bed can be achieved, OPEN THE BYPASS DOOR AND THEN THE LOADING
DOOR and stir up the kindling to form the coal bed. Ensure it is evenly distributed over the entire fi rebox fl oor.
11. With both the loading door and bypass door still open, insert your main fi rewood load (see step 9 for ideal
orientation). Once loaded, CLOSE YOUR LOADING DOOR AND THEN YOUR BYPASS DOOR IMMEDIATELY.
12. Let the appliance burn with the thermostat set to HIGH for 10 – 20 minutes or until the fi re is well established.
Turning the thermostat down too soon could cause the fi re to go out.
13. Once satisfi ed that the fi re is fully established, the thermostat can be adjusted down to the desired heat output
setting.
14. The fan can be turned on once the appliance is hot or 20-30 minutes after the initial loading period.
OPERATING INSTRUCTIONS
AF25
It is good burning practice to burn the stove on HIGH for 20 to 30 minutes after every refuelling, this will help to condition
the wood load for optimum combustion. The temperature in the stove and the gases entering the combustor must be
raised to at least 500° (indicated by the thermometer needle in the active red zone) for catalytic activity to be initiated.
During the start-up of a cold stove, a high fi re must be maintained for at least 20-30 minutes. This ensures that the stove,
catalyst, and fuel are all stabilized at proper operating temperatures. Even though it is possible for fl ue gas temperatures
to reach 600° within 5 minutes of a fi re being started. If the fi re is allowed to die down immediately (thermostat set to a
LOW setting too soon), it may go out or the combustor may stop working, indicated by the thermometer needle being in
the inactive zone. Once the combustor starts working, heat generated in it, by burning the exhaust smoke, will keep it
working.
Probably the least understood requirement in maintaining a good fi re is that of establishing a good base of coals or
embers. A good bed of hot coals or embers will maintain a more even temperature as well as getting the new load of
wood started easily
King automatic thermostat, the wood will only burn at the rate set on the thermostat. Once the full load is established,
the stove should be left to complete the full burn cycle. This is evident by either a coal bed (ember bed) remaining or the
catalyst’s thermometer hovers just inside the active zone. This procedure will maximize the effi ciency of the combustor as
well as limit chimney emissions and smoke spillage.

RELOADING PROCEDURE (with the catalyst temperature in the active red zone)
1. Have your next load of wood ready before beginning. Turn the thermostat to HIGH and turn the fan off .
Wait 2 minutes for the air fl ow to stabilize.
2. Open the bypass door (bypass latch / rod pulled out using bypass handle) and again wait 2 minutes for the
air fl ow to stabilize.
3. Unlatch the loading door and open just a crack to allow the ambient room air to be introduced to the
fi rebox, this may take a few seconds to stabilize.
4. Slowly open the loading door and proceed to reload the fi rebox. If you experience excessive smoke
spillage, slightly close the loading door to re-establish a draft through the chimney.
5. Once loaded, latch the loading door shut and close the bypass door (push the bypass latch / rod in using
the bypass handle). Let the fi re burn on the HIGH thermostat setting for 20 to 30 minutes OR until the fi re
is very well established. At that point, turn the thermostat down to the desired setting. Keep in mind you
may not see a large amount of fl ame activity in the lower thermostat setting. The thermometer needle will
remain in the active zone indicating that the burn cycle is continuing.
6. Should you burn the stove on a very low setting for extended periods of time, you will begin to see
creosote deposits forming on the glass door. To remove these deposits, simple run the stove on HIGH for
approximately 30 minutes. The HIGH setting will burn off most of the deposits
As every pile of wood is diff erent you will learn, over time, which settings are necessary to achieve the optimal
fi re. This will be based on the type of wood, installation, weather conditions and the desired room temperature.
RELOADING PROCEDURE (with the catalyst temperature still in the inactive zone)
Follow the procedure for “LIGHTING THE FIRE” on the previous page.

OPTIMAL THERMOSTAT SETTING
Any thermostat position between LOW and HIGH will produce the desired clean burning characteristics.
However, since each application can vary, you may fi nd it necessary to operate the thermostat to suit your
application. A thermostat setting on HIGH will produce a maximum heat which is more than suitable for
heating the average size home and off er the cleanest door glass.
1. Starting the fi re. Each stove, home, installation, chimney installation, and homeowner combination
works a little diff erently. The fi rst several times you fuel the stove, it may not react as you expect. A
little experimentation may be needed to fi nd the right combination of fuel and thermostat setting to
achieve the maximum effi ciency. This is one of the joys of burning wood. You, the wood burner,
make it work. And you can see what happens as it is working. Be patient, the air / fuel mixture and
temperature must be stabilized before maximum combustion effi ciency can be achieved.
2. As the combustor temperature (as indicated by the thermometer) passes into the active red zone,
further adjustment to achieve the desired room temperature should be made in small increments for the
most eff ective cleaner burning operation. Changes should be made as few times each day as possible.
When the thermostat knob is moved from high to low, more gases are produced, so the combustor has
more fuel; consequently the combustor thermometer may register a higher heat for several hours after
the thermostat is turned down.
3. Keep hot coals active so when you reload the stove you will reduce the time necessary to maintain an
active combustor.
4. The thermostat is set at the factory. DO NOT TAMPER WITH THE THERMOSTAT, this will result in a
malfunctioning thermostat.
OPERATING INSTRUCTIONS
AF25
FAN OPERATION
The fans are located beneath the fi rebox of the stove, it recirculates room air up the back and across the
top. This design allows the air to travel the farthest distance across the hot surfaces resulting in super heated
air, most of which can be felt exiting the top of the stove. The fan should be off until the stove reaches
normal operating temperatures. After approximately 30 minutes, the fan speed adjustment should match the
thermostat control setting, i.e. if your stove is set at medium then your fan should also be set at medium, low—
low, high—high etc. The fan control is on the right-hand side of the lower shroud / ash shelf.
ICE - FORMATION AND PREVENTION
Most of what you see coming from the chimney of a properly operating catalytic appliance is water vapor. In
extremely cold weather - and with some exterior chimneys - this vapor may freeze in the chimney to the point
of actually blocking the chimney and extinguishing the fi re. In such weather, occasionally burn the appliance
for 4 or 5 minutes with the thermostat setting on HIGH to melt any possible ice buildup.

WOOD BURNING IN THE SHOULDER SEASON
There are things to consider if you decide to light a fi re in the spring and fall or when the outside temperature is
milder, perhaps 55°F to 70°F (13°C to 21°C).
As you light the fi re, with the loading door open, you may notice spillage, this is when a small amount of smoke
comes back into the living space. When your fi re begins to warm the chimney and the draft improves, spillage
is greatly reduced. After a short period of time you can adjust the thermostat to a LOW setting and maintain a
comfortable temperature in your home.
In reducing the thermostat setting you have also reduced the fl ue temperatures and your chimney begins
to cool down. At this time the amount of draft is also decreasing and spillage may occur. The diff erences
between the fl ue temperature and the outdoor air temperatures causes your chimney to draw and vent the
fl ue gasses to the outside. This air movement, sometimes referred to as Stack Eff ect, is also infl uenced by air
density and moisture diff erences. Small temperature diff erences produce less draw in your chimney system
than large temperature diff erences.
General Rules for burning in the shoulder season:
• Run your appliance on high for 30 minutes after start up and reloading.
OPERATING INSTRUCTIONS
Page 27
• Slowly turn the thermostat down to the desired heat setting.
• The heat setting needs to be high enough to keep the thermometer in the active zone.
• If the thermometer does not stay in the active zone turn the thermostat to a higher setting. Wait 15 minutes
then confi rm that the thermometer remains in the active zone. Repeat as needed.
• If your appliance is producing too much heat, build smaller hotter fi res.
• Build smaller hotter fi res on milder days in the spring and fall.

It is important to periodically monitor the operation of the catalytic combustor to ensure that it is functioning
properly. A non-functioning combustor will result in a loss of heating effi ciency, and an increase in creosote
and emissions. Following is a list of items that should be checked on a periodic basis:
• Combustors should be visually inspected at least three times during the heating season to determine if
physical degradation has occurred. Actual removal of the combustor is not recommended unless more
detailed inspection is warranted because of decreased performance. Refer to “CATALYTIC COMBUSTOR
TROUBLESHOOTING” on next page.
• This catalytic heater is equipped with a temperature probe to monitor catalyst operation. Properly
functioning combustors typically maintain temperatures in excess of 500°F (indicated by the thermometer
needle in the active zone), and often reach temperatures in excess of 1000°F. If catalyst temperatures
fall below 500°F (indicated by the thermometer needle in the inactive zone), refer to next step and to
“CATALYTIC COMBUSTOR, TESTING” below.
• You can get an indication of whether the catalyst is working by comparing the amount of smoke leaving the
chimney when the smoke is going through the combustor and catalyst light-off has been achieved, to the
amount of smoke leaving the chimney when smoke is not routed through the combustor (bypass mode):
- Light the appliance as per the lighting instructions (see “LIGHTING THE FIRE”). With smoke routed
through the catalyst, go outside and observe the emissions leaving the chimney.
- Open the bypass mechanism, wait approximately 15 minutes, and again observe the emissions leaving
the chimney. Signifi cantly more smoke will be seen when the exhaust is not routed through the combustor
(bypass mode). Some smoke may be visible shortly after you start the fi re and shortly after reloading the
fi re. Allow 20 to 30 minutes for the fi re to stabilize before making observations.
CATALYST MONITORING
AF25
CATALYTIC COMBUSTOR, TESTING
Light the fi re as per the lighting instructions (see LIGHTING THE FIRE). Then set the thermostat knob on a
MED setting. When the fi re is well established (within one to three hours) turn the thermostat knob between
LOW and MED. A properly operating combustor will remain active, and the combustor thermometer will
remain in the “active” zone until the wood load is mostly consumed. A “tired” or “dead” combustor will, with
the thermostat on MED or lower, go out completely, and the thermometer needle will fall into the “inactive”
zone. Repeat this procedure several times over several days (Remember that the combustor thermometer
has a built-in lag of 4-8 minutes.) If, after several test burns, the thermometer will not indicate an “active”
combustor, it may require cleaning or replacement. It is also possible that the thermometer, itself, may not
be reading accurately. Before condemning the combustor, read “THERMOMETER”. If, after cleaning has
been performed, your combustor is still not working you can Contact Blaze King for a replacement combustor.
Please read “REPLACEMENT PARTS” section in this owners’ manual.
CATALYTIC COMBUSTOR, CLEANING
Under certain conditions, ash particles may become attached to the face of the combustor. These may be
seen while the combustor is in the glowing stage, or when the fi re is out. Any deposit on the visible face
of the combustor should be removed. Wait until the fi re is out and the appliance is cold before performing
any cleaning. Brushing the combustor with a soft bristle paint brush will remove some deposits. Passing
a vacuum cleaner wand or brush near the face of the combustor will remove most deposits. (Hot ash in a
vacuum cleaner bag will burn, may melt the vacuum or cause a house fi re. Exercise caution and never clean
the appliance when the appliance or ashes are hot.) Never scrape the combustor with any hard tool or brush.
Never run pipe cleaner through the individual cells of the combustor. This is not needed, and may do more
harm than good. Limit cleaning to the face of the combustor. NOTE: Never remove a combustor without
approved combustor gasket in hand as original gasket will fall apart when removed from appliance.
Remember to re-install the Flame Shield (the perforated plate) in same position it was found.
TIP: A hot fi re will usually prove to be the best method of cleaning the combustor of deposits.

CATALYST MONITORING
CATALYTIC COMBUSTOR, TROUBLESHOOTING
PROBLEM - CREOSOTE PLUGGING
Possible Cause: Burning materials that produce a lot of char and
fl y-ash.
Solution: Do not burn materials such as garbage, gift wrap, or
cardboard.
Possible Cause: Burning wet, pitchy woods or burning large
loads of small diameter wood with the combustor in the operating
position without the thermostat needle in the active zone.
Solution: Burn dry, seasoned wood, don’t engage the bypass
until the temperatures are high enough to initiate light-off
(indicated by the thermostat needle in the active zone).
Possible Cause: Combustor not functioning. If proper burning
procedures have been followed to no avail, the combustor is not
functioning.
Solution: Replace the combustor with a genuine Blaze King
combustor (failure to do so will void your warranty).
Page 29
PROBLEM - CATALYST PEELING
Possible Cause: Extreme temperatures (above 1800°F, or
1000°C.) at combustor surface can cause the catalysts to peel.
Over fi ring and fl ame impingement on the combustor are primary
causes. Minor peeling photo shows minor peeling that is normal
and does not aff ect function. Severe peeling photo shows that are
closed or plugged.
Solution: Avoid extreme temperatures and fl ame impingement.
If peeling is severe, remove and replace combustor.
PROBLEM - CATALYST DEACTIVATION
Possible Cause: Burning large quantities of trash, pressure-
treated lumber, or painted woods.
Solution: Burn quality woods available in your area. If you
decide the catalyst has been deactivated, replace combustor with
a genuine Blaze King combustor (failure to do so will void your
warranty).

PROBLEM - CATALYST MASKING
(The catalyst is coated with a layer of fl y-ash
or soot which prevents catalytic activity)
Possible Cause: Accumulation of fl y-ash
Solution: Brush cooled combustor with a soft-bristled brush or
vacuum lightly at least once per burning season.
PROBLEM - THERMAL CRACKING
Possible Cause: Normal operation, as long as the combustor
remains intact.
Solution: If cracking causes large pieces to fall out, replace the
combustor.
CATALYST MONITORING
AF25
PROBLEM - MECHANICAL CRACKING
Possible Cause: Mishandling, abuse, or operating without a
properly gasket sealed combustor.
Solution: Handle with care
Possible Cause: Distortion of holding collar.
Solution: Combustor should be held fi rmly in its can. It should
slide easily into and out of the holding collar of the stove. If
severe cracking has resulted in loss of large chunks of combustor,
replace combustor. Also replace any warped stove parts.
PROBLEM - CRUMBLING
Possible Cause: Air leaks
Solution: Inspect door gasket, see “MAINTENANCE cont.” on
page 35.
Possible Cause: High draft
Solution: Maintain draft to manufactured specifi cations.

CATALYTIC COMBUSTOR, REPLACEMENT
BLAZE KING RECOMMENDS YOUR DEALER PERFORM THIS TASK
The catalytic thermometer on top of the stove should read in the active zone after the stove has been in
operation for several hours. If the thermometer’s indicator needle does not stay in the active zone, even
with a hot fi re, over a 7-10 day period of regular use, the combustor may need replacement or cleaning, see
“CATALYST MONITORING”. If the combustor needs replacing then discontinue use of the appliance until the
combustor is replaced. If the combustor must be examined or replaced contact your Blaze King dealer.
CATALYST MONITORING
1. The removal of a Blaze King Catalytic combustor requires
a small fl at blade screwdriver or pocket knife. The stove fi re
must be out for at least 12 hours prior to the removal process.
A combustor can reach 1400°F and hold high temperatures for
several hours even after the fi re is out. After waiting 12 hours,
fi rst remove the fl ame shield by simply lifting the shield off the two
tabs at either side. Pay particular attention to orientation as there
is a top and bottom edge to the fl ame shield.
Page 31
2. Once you remove the fl ame shield, you’ll fi nd the combustor.
The honeycomb combustor can be made of diff erent materials
such as cordierite, mulite or even stainless steel. They are all
the same with regard to removal and caution should be taken so
as to not drop or damage the combustor. If your combustor has
never been cleaned according the manufacturers directions, you
may wish to clean the combustor before replacing it with a new
combustor, see “CATALYTIC COMBUSTOR CLEANING”.
3. The combustor has a metal tab across the bottom and on each
side of the combustor. Using a fl at blade screwdriver or pocket
knife blade, slide the blade behind the metal tab and the heavy
steel dome of the stove. The dome is the housing that surrounds
the combustor. Apply slight pressure until the combustor begins
to move forward, about 1/4”. Repeat the process on the opposite
end tab. By working back and forth the combustor will work free
of the dome housing. It is normal for the gasket surrounding the
metal band to fall apart during this process. New combustors are
shipped with a new gasket.
180-AF25 v1.07 October 2, 2018
Page 32
Page 32
CATALYST MONITORING
4. Now that the combustor has been removed you’ll be able to see
one stainless bypass retainer on each side. These can remain in
place and do not need to be removed. These clips are not fi xed in
position and can fall into the fi rebox. Make sure they are in position
before replacing the combustor. Using the same screwdriver or
pocket knife, scrape any old gasket from the surface areas of the
dome. The dome is the housing that surrounds the combustor. If
you clean your existing combustor, you’ll need to order replacement
combustor gasket. It is always a good idea to have a spare
combustor gasket on hand prior to performing any maintenance. If
you purchase a new combustor a new gasket will already be applied
to the combustor.
5. This new combustor already has the gasket installed. Note
the 1” wide masking tape. This tape will help to keep the leading
edge of the gasket from snagging during installation. If you’ve
cleaned your combustor, wrap the combustor gasket as you see
here and use the 1” masking tape around the perimeter front and
rear. During the fi rst fi re the masking tape will burn off and the
combustor gasket will swell providing a tight seal. It is this tight
seal that improves effi ciency and performance. You should never
burn your stove without a combustor gasket installed.
AF25
6. Since the combustor is only 2” deep, there is ample room to lift
the new combustor into place. REMEMBER TO HAVE THE TAB
ACROSS THE BOTTOM EDGE OF THE COMBUSTOR AS IT IS
INSTALLED. Slowly push the combustor in at the top apply even
pressure to the left and right corners. This will allow for a better
view of the bottom edge for the fi nal fi tting. DO NOT FORCE
THE COMBUSTOR INTO THE DOME. TAKE YOUR TIME AND
WORK IT INTO PLACE SLOWLY.
180-AF25 v1.07 October 2, 2018
Page 33
AF25
CATALYST MONITORING
7. Once the combustor is installed completely so that all three
tabs at touching the face of the dome, replace the fl ame shield.
Note the brackets welded to the back fl ame shield are shaped
like a triangle.The point of the triangle should face down when
installed correctly. Never operate your stove without the fl ame
shield in place. The fl ame shield will protect the face of the
combustor against damages from wood when loading and other
possible damages that can occur during the cleaning process.
8. The fl ame shield will rest on the two tabs located on the dome
guard and lean slightly forward. Now that your combustor has
been installed you can relight your stove. You will continue to
receive excellent effi ciency and clean burning for years to come.
A few reminders, never burn anything other than dry, seasoned
cordwood. Burning anything else may contaminate or ruin your
new combustor. Also remember to keep your front loading door
gasket seal properly adjusted, see “LOADING DOOR TENSION
ADJUSTMENT”. Doing so will improve burn times and extend
combustor life span.

RUN-AWAY OR CHIMNEY FIRE
A CHIMNEY FIRE CAN PERMANENTLY DAMAGE YOUR CHIMNEY SYSTEM. THIS DAMAGE CAN
ONLY BE REPAIRED BY REPLACING THE DAMAGED COMPONENT PARTS. CHIMNEY FIRE
DAMAGE IS NOT COVERED BY THE LIMITED WARRANTY.
CAUSES:
1. Using incorrect fuel, or small fuel pieces which would normally be used as kindling.
2. Leaving the door ajar too long and creating extreme temperatures as the air rushes in the open door.
3. Improperly installed or worn gaskets.
4. Creosote build up in the chimney.
SOLUTIONS:
1. Do not burn treated or processed wood, coal, charcoal, colored paper or cardboard.
2. Be careful not to over fi re the appliance by leaving the door open too long after the initial start-up.
3. Replace worn, dried out (infl exible) gaskets.
4. Have your chimney cleaned regularly.
MAINTENANCE
AF25
WHAT TO DO IF A RUN-AWAY OR CHIMNEY FIRE STARTS:
1. Close the draft fully (lowest position) by shutting off thermostat, and make sure fi rebox is closed tightly.
2. Call the local fi re department.
3. Examine the chimney, attic and roof of the house, to see if any part has become hot enough to catch
fi re. If necessary spray with a fi re extinguisher or water from a garden hose.
4. Do not operate the appliance again until you are certain the chimney has not been damaged.
CREOSOTE FORMATION AND REMOVAL
When wood is burned slowly, it produces tar and other organic vapors which combine with expelled moisture
to form creosote. These vapors condense in the relatively cooler chimney fl ue of a slow burning fi re and when
ignited, make an extremely hot fi re. Check your chimney for creosote and soot regularly, until a safe frequency
for cleaning is established. The chimney connector and chimney should be inspected regularly during the
heating season to determine if a creosote build up has occurred. Be aware that the hotter the fi re, the less
creosote is deposited.
If accumulation is excessive, clean the chimney. You may want to call a professional chimney sweep to clean
it. Both the chimney and the appliance have to be cleaned at least once a year or as often as necessary.
Have a clearly understood plan to handle a chimney fi re.
180-AF25 v1.07 October 2, 2018
Page 35
AF25
CHIMNEY MAINTENANCE
The most effi cient method to sweep the chimney is using a hard brush. Brush downwards so soot and
creosote residues will come off the inner surface and fall to the bottom of the chimney where they can be
removed easily.
The chimney must be checked regularly and if creosote has accumulated, it must be removed without delay.
Cleaning on a regular basis should be suffi cient during the coldest months. ENSURE THE BYPASS DOOR
IS OPEN PRIOR TO CLEANING THE CHIMNEY SO THE SOOT AND CREOSOTE FALLS INTO THE
FIREBOX.
Chimney / Flue Inspection: The chimney should be inspected regularly during the heating season for possible
damage and repaired or replaced if necessary.
FLUE COLLAR ADAPTER
If for any reasone the Z2015 fl ue collar assembly is unbolted from the fi rebox than the 1/4” fl ue collar
gasket (#2055) needs to be replaced before reinstallation.
FIRE EXTINGUISHERS AND SMOKE DETECTORS
All homes with a solid fuel burning appliance should have at least one fi re extinguisher in a central location,
known to all, and at least one smoke detector in the room containing the appliance. If it sounds an alarm,
correct the cause but do not de-activate or relocate the smoke detector.
MAINTENANCE
Page 35
ASH REMOVAL
This appliance is required to be cleaned frequently because soot, creosote and ash may accumulate. Wait
until the appliance is fully cooled off before the removal of ashes. ALWAYS REMOVE THE ASH BUCKET
IMMEDIATELY AFTER FILLING. Ashes should be removed any time they come within one inch of the door
opening. It is not necessary or advisable to completely remove all of the ashes when cleaning this appliance.
Wood burns best in a bed of ashes 1/2” thick. Ashes should be placed in a metal container with a tight fi tting
lid. The closed container of ashes should be placed on a noncombustible fl oor or on the ground (outside), well
away from all combustible materials, pending fi nal disposal. If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly
cooled. Other waste shall not be placed in this container.
NEVER STORE HOT ASHES IN A GARAGE OR BASEMENT. HOT ASHES WILL GENERATE
CARBON MONOXIDE AND / OR FLAMMABLE GASES. THESE GASES MAY CAUSE
SUFFOCATION AND POSSIBLE DEATH.

LOADING DOOR GASKET INSPECTION
Inspect the door gasket for physical deterioration, missing sections or obvious leakage. The appliance front
should make a groove in the gasket material - one side of the groove (toward the inside) will often be dark or
black, and the other side (toward the outside) should be light or white. Dark smudges on the outside of the
groove may indicate an air leak. If the groove is very shallow or missing, or if there is a heavy ash or creosote
deposit along the bottom edge of the gasket, it may need to be replaced. Frayed or broken gasket material,
or a gasket that is hard and unyielding, will also indicate need for replacement. Any time a piece of gasket is
missing or is broken anywhere, the entire gasket must be replaced.
To check the gasket further, wait until the appliance is cooled and insert a piece of paper (a dollar bill will work)
into the door opening and close and latch the door. Obvious resistance should be felt when pulling the paper
out Repeat this check several times around the perimeter of the door.
LOADING DOOR GASKET REPLACEMENT
BLAZE KING RECOMMENDS YOUR DEALER PERFORM THIS TASK
1. If the door gasket is to be replaced, be sure you have Blaze King 7/8” fi ber glass door gasket ready to
re-install, as well as high temperature adhesive. See your Blaze King dealer.
2. Be sure the fi re is out and the stove has cooled down. The door does not have to be removed from the
stove.
3. With a pair of pliers, pull the old door gasket out of the channel and dispose of it.
4. Thoroughly clean out the channel so the new silicone adhesive will adhere and the gasket will fi t
smoothly.
5. Dry fi t the new gasket fi rst to ensure proper fi t. Do not stretch or cut the gasket. Distribute the gasket
evenly around the frame.
6. Run a small bead of a high temperature silicone adhesive along the center of the channel. DO NOT
USE HOUSEHOLD SILICONE CAULKING. High temperature silicone may be obtained from wood
stove dealer.
7. Start the new gasket in the lower right corner. Do not stretch or cut the gasket. Distribute the gasket
evenly around the frame.
8. Allow the adhesive to dry before closing the loading door. The loading door tension may need to be
adjusted, see “LOADING DOOR TENSION ADJUSTMENT” on page 40.
9. Check the fi t of the door gasket. Insert a narrow strip of paper into the door opening and close and
latch the door. Obvious resistance should be felt when pulling the paper out. Repeat this check
several times around the perimeter of the door. If no resistance is felt, adjust door latch catch, see
“LOADING DOOR TENSION ADJUSTMENT” on page 40.

and installation. Replace only with ceramic glass, 5 mm. thickness. Follow steps 4 and 5 in “DOOR GLASS
GASKET REPLACEMENT” to install the new glass.
DOOR GLASS, CLEANING
The best way to keep the glass clean is to leave the appliance on high burn for a period of time after each
reloading The moisture which is driven from a new load of wood contributes much of the creosote on the
inside of the glass. Removing that moisture at the beginning of the burn cycle helps to keep the glass clean.
Leaving the thermostat on a higher setting for 30 minutes to an hour before turning to low for an overnight burn
will also help. Heavier deposits may require hand cleaning. Manual glass cleaning should be done when the
appliance and glass are cool. DO NOT CLEAN THE GLASS WHILE IT IS HOT. WARNING: Do not use
abrasive cleaners to clean the glass. Use a soft cloth. After using any cleaner, thoroughly rinse the glass
with water to remove any deposits left by the cleaner. Failure to remove all traces of glass cleaner will result in
the glass cleaner residue baking on. This residue may be very diffi cult to remove.

Your Blaze King is designed to allow a wide selection of heat output levels. If you begin to lose control of the amount of
heat the stove is emitting, determine the cause early so that major problems may be avoided.
The six major needs of a well-controlled fi re are:
TROUBLESHOOTING
AF25
1. Knowledgeable operator.
2. Adequate air supply.
3. Firewood of good quality and proper size.
4. Catalytic combustor in good condition.
5. Clean chimney, properly sized and installed.
6. Door gasket tight and fi rm.
Considering all of the above, number one is the most important for safe and effi cient operation of any woodstove. Please
study the operation instructions carefully. Consult your BLAZE KING dealer or call the Customer Service Department at
Blaze King in the U.S.A. at 509-522-2730 or in Canada at 250-493-7444 if you have any questions not answered in this
manual.
All of the six above mentioned needs are interrelated. A defi ciency in any one will aff ect all of the others. If you encounter
a problem, determine the source of the problem and then follow-up by checking the other needs as possible contributing
factors.
PROBLEM: Chimney Fire
CAUSE
Act immediately regardless of cause
A er the re is out, have your chimney and ue connector inspected by a certi ed chimney sweep. A damaged masonry chimney
should be repaired or rebuilt. A prefabricated chimney (factory built) that is damaged should be replaced. Any damage to the ue
connector should be corrected before the system is used again.
SOLUTION
Turn the thermostat to lowest setting, check loading door to be
sure it is tightly closed.
Call Fire Department.
Possible causes of a chimney re, and remedies for those causes, can be found further in this section: “Excessive Creosote Formation”,
and “Spots of Creosote Accumulation in Chimney or Flue Connector”.
PROBLEM: Not enough heat.
CAUSE
Green or wet wood.
Not enough fuel in stove.
Obstruction in chimney or cap screen.
Combustor plugged or coated.
Combustor not functioning. See “COMBUSTOR, TESTING”.
Thermostat set too low. Raise thermostat setting.
Thermostat not operating properly. Consult your Blaze King dealer.
Poor draft caused by an oversize fl ue Measure draft with Manometer. See “CHIMNEY DRAFTS”
Strong, gusting winds causing downdraft in
chimney
Tightly sealed house, inadequate air supply. Slightly open a window, near the stove or install an outside air kit.
SOLUTION
Use seasoned wood. Don’t be afraid to FULLY load the stove. A
FULL load of wood won’t burn any hotter than the thermostat is
set.
Remove obstruction. See “COMBUSTOR, TESTING”
See “COMBUSTOR, CLEANING”
If needed, replace combustor, See”“COMBUSTOR, REPLACING”.
Consult your Blaze King dealer or a chimney sweep.
Install wind-resistant chimney cap. Directional caps may not stay
freely rotating. If you have a directional cap, check it frequently.
Reloading too much wood on top of too few coals. Allow a larger bed of coals to build up.

Burning poorly seasoned wet wood, or wood with
high pitch content.
PROBLEM: The combustor temperature cannot be controlled. Turning the thermostat down often makes the
combustor temperature go up.
CAUSE
Turning the thermostat down, particularly in the fi rst half of the burn cycle, causes the fi re to emit more smoke, which is
fuel for the combustor. The combustor temperature therefore climbs for up to several hours. This is normal, and is of no
concern. As long as only the combustor temperature is elevated, there is nothing to worry about.
SOLUTION
Inspect chimney and / or chimney connector. Repair or replace
as necessary. Check to be sure that the chimney connector is
installed correctly.
Measure draft with Manometer. See “DRAFTS”. Consult your
Blaze King dealer or a chimney sweep.
SOLUTION
Turn the thermostat to the warmest setting during the fi rst 20-30
minutes or until the fi re is well established after each reloading.
