CHIMNEY CONNECTIONS
AF25
THIS APPLIANCE MUST BE INSTALLED WITH A CONTINUOUS CHIMNEY LINER OF 6″
DIAMETER EXTENDING FROM THE APPLIANCE TO THE TOP OF THE CHIMNEY. THE CHIMNEY
LINER MUST CONFORM
TO THE CLASS 3 REQUIREMNETS OF CAN/ULC-S635, STANDARD OR LINING SYSTEMS FOR
EXISTING MASONRY OR FACTORY BUILT CHIMNEYS AND VENTS, OR CAN/ULC-S640,
STANDARD FOR LINING SYSTEMS FOR NEW MASONRY CHIMNEYS. FAILURE TO COMPLY MAY
RESULT IN A HOUSE FIRE CAUSING SERIOUS BODILY HARM.
COMBUSTION AIR In air tight homes (most modern construction), careful
considerations must be taken into account before installing a wood burning
appliance. It is important to ensure there is adequate intake (combustion) air
for all exhausting type appliances within the dwelling. Heat recovery
ventilator (HRV) systems along with constant running fan motors in air
handlers are examples of appliances that must be taken into account when
balancing intake air (others include fireplaces, range hoods, dryers, etc.).
It is recommended that a fresh air intake inlet into the room where the
appliance is located be installed. Failure to do so may result in air
starvation, smoke spillage, and carbon monoxide threats. Consult a HVAC
specialist for proper installation practices.
DRAFT PERFORMANCE Draft is the movement of combustion air into the appliance
and out through the chimney as exhaust gas. In essence, it is the difference
in pressure between the exhaust gas inside the chimney and the outside air
that creates this movement. Warmer, lighter exhaust gasses in the chimney tend
to move upward. The amount of draft created by your chimney can depend on
chimney length, horizontal offsets, insulating properties, local geography,
external forces, and other factors. External factors (outdoor temperature,
wind, barometric pressure, topography, etc.) or internal factors within the
dwelling (negative pressure from exhaust fans, chimneys, air infiltration,
etc.) may adversely affect draft.
Too much draft can yield very high temperatures within the appliance and may
result in damage. An uncontrollable burn or excessive room temperatures are
indicators of too much draft. Too little draft may cause back puffing (smoke
spillage) into the room and plugging of the chimney, chimney cap, or spark
arrestor screen. Inadequate draft can also lead to low heat output and the
inability for the combustor to remain active at low burn rate settings. Your
Blaze King heater is a high efficiency appliance and will require fine tuning
of your chimney system in order to maximize draft performance. Blaze King
cannot be responsible for external forces leading to less than optimal draft
performance.
ROLE OF THE CHIMNEY The role of the chimney is to maintain sufficient draft to
achieve complete combustion. To ensure maximum performance, Blaze King
recommends a minimum vertical chimney height of 15ft (from stove top to
termination) when installing an appliance at sea level (and up to 1000ft of
elevation). For freestanding installations, it is also recommended to use
double wall pipe from stove top adaptor to ceiling support box. Double wall
pipe helps to keep the chimney warm and improve draft performance. For wall
exit installations, a vertical length of 3ft from stove top to elbow is
recommended. It is also recommended to use a pair of 45 degree elbows rather
than a single 90 degree elbow to allow for a smoother transition of airflow.
When possible, outside chimney systems should be isolated from the external
environment by building a chase around the chimney. Doing so will help keep
the chimney warm and maintain sufficient draft (please refer to the
“RECOMMENDED FLUE HEIGHTS” section). Without a properly installed chimney,
this appliance will not operate at its maximum performance which could yield
incomplete combustion leading to more smoke exiting the chimney system.

CHIMNEY CONNECTIONS

VENTING SYSTEM All joints within the venting system must be securely fastened
with sheet metal screws. Place a bead of furnace cement around the flue collar
connection to ensure the flue pipe is properly connected, secured, and sealed.
Do not use a flue pipe to pass through an attic or roof space, closet or
similar concealed space, or a floor or ceiling as in the event of a creosote
fire, temperatures inside the chimney may exceed 2000F (1100°C). An effective
vapor barrier must be maintained at the location where the chimney or vent
component penetrates to the exterior of the structure. Do not connect this
appliance to a chimney serving another appliance; To do so will affect the
safe operation of both appliances and will void the appliance warranty. You
must comply with the local authority having jurisdiction.
CONNECTION TO A MASONRY CHIMNEY It is recommended that the inner, cross
sectional area of the masonry chimney be no less than the area of the
appliance flue (28in² or 180cm²). Ensure the masonry chimney meets the minimum
standards per the National Fire Protection Association by having it inspected
by a certified professional. There must be no cracks, no loose mortar, and no
signs of deterioration or blockage. Ensure the chimney is properly cleaned
before installing the appliance.
Masonry or steel, including the damper plate, may be removed from the smoke
shelf and adjacent damper frame if necessary to accommodate a chimney liner,
provided that their removal will not weaken the structure of the fireplace
and/or chimney, and will not reduce protection for combustible materials to
less than that required by the National Building Code. If the fireplace is
modified to accomidate the appliance, the qualified installer must attached a
metal tag (supplied by the manufacturer) with screws or nails to the fireplace
in a location that is readily visible should the appliance be removed. The tag
will state: “This fireplace has been altered to accomidate a fireplace insert
and should be inspected by a qualified person prior to re-use as a
conventional fireplace.”
Blaze King recommends the use of a stainless steel liner, preferably
insulated, inside a masonry chimney. This is to help maintain a proper draft
to achieve optimal performance of the appliance. A rough masonry chimney
without a good smooth liner can result in the rapid build up creosote.
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.

RECOMMENDED CHIMNEY HEIGHTS
Every installation is unique, especially when considering geographical
location. As previously mentioned, maintaining sufficient draft is of utmost
importance, but this can be a challenge as draft can be heavily influenced by
topographical and geographical phenomena. The understanding of pressure planes
and the stack effect are imperative in planning and executing a successful
installation.
As previously mentioned, Blaze King recommends a minimum vertical chimney height of 15 feet (from stove top to termination) when installing an appliance at sea level (and up to 1000 feet of elevation). If the install is at a higher elevation, please refer to the table below for recommended chimney heights:

NOTE: No more than one offset (two elbows) are allowed. Two 45°elbows equal one 90° elbow
For other common chimney components, use the following vertical height(s) to compensate for: 90° elbow = 2.0 ft (0.610 m) “T” section = 3.0 ft (0.915 m) 1.0 ft (0.305 m) of horizontal run = 2 ft (0.610 m) of vertical rise
Example Chimny Height Calculation (at sea level):
Min Chimney Height = 15.0 ft (4.575 m)
One 90° Elbow
= 2.0 ft (0.610 m)
2.0′ Horizontal Run = 4.0 ft (1.200 m)
One Base “T”
= 3.0 ft (0.915 m)
Final Chimney Height = 24.0 ft (7.3 m)
The above figures are only guidelines, please refer to the “DRAFT PERFORMANCE” section.

INITIAL SETUP
Note: This appliance is shipped with all cast iron
pieces attached causing it to be “front heavy” and
difficult to manuver when installing. Though not
required, the front cast assembly can be removed
to ease positioning of the appliance infront of the
fireplace opening and the reattached after.
FRONT CAST ASSEMBLY REMOVAL Disconnect the x2 rheostat wires from the front cast assembly. Use a 7/16″ wrench to remove the nuts from the top and side brackets (x8 total). Use a 3/8″ wrench to remove the x2 nuts from the catalytic thermometer. Open the loading door and slide the cast assembly out from the firebox and set aside.

INSTALLATION INSTRUCTIONS
FLUE COLLAR ASSEMBLY REMOVAL From within the firebox, use a 9/16″ wrench to
remove the x2 nuts that hold flue collar assembly in place and then remove the
assembly from the rear. Ensure the gasket is still fully intact and adhered to
flue collar base. (Fig. 2)
THERMOSTAT ROD INSTALLATION Note: The front cast assembly must be reattached
at this time in order to continue with Initial Setup. First, ensure the fans
are in correct position and have not shifted during transport. Ensure the
thermostat is in the fully open position with the set screw making contact
with the stop (see below). Slide the thermostat rod in through the left cast
side and align its machined face with the machined face of the rod protruding
from the thermostat. With both rods fully interlocked, secure them in place by
tightening the grub screw in the set collar supplied with the thermostat rod.
(Fig. 3)
AF25

INSTALLATION INSTRUCTIONS
SHROUD KIT INSTALLATION Note: Follow the instructions provided with the shroud
kit in order to fully assemble prior to installing onto the appliance.
Position the assembled shroud tight to the rear of the front cast assembly and
fasten it to the firebox with the x7 screws provided with the kit. The bypass
door handle bracket can be placed on either side of the shroud. (Fig. 6)
FIREPLACE INSTALLATION Before sliding the appliance into the fireplace
opening, determine how much levelling will be required to ensure a proper
installation as the appliance must sit level and be slightly higher than the
protruding hearth front. Using a 5/32″ wrench, unfasten the x2 bolts (Fig. 7)
securing the lower cast front to the cast assembly then locate the x4
levelling bolts at the front and rear corners of the appliance (Fig. 8) which
must be adjusted accordingly to insure a level installation. Once satisfied
with level, reinstall the lower cast front.
BYPASS HANDLE BRACKET

Fig. 6
Note: If additional levelling is required, use only non-combustible material
to fill any space under the appliance (ie. firebricks). Note: The leveling
bolts may make it difficult to slide the appliance over a rough hearth. To
remedy this, there are x2 metal strips supplied with the appliance. Position
the strips below the levelling bolts and slide the appliance into the
fireplace.

FLUE COLLAR INSTALLATION 1. Once the liner has been dropped down the chimney,
it must be securely attached to the flue collar
assembly (refer to the “CHIMNEY CONNECTIONS” section). Note: Ensure the flue
collar assembly will hang roughly 2′ (607 mm) above the floor of the fireplace
once attached to the chimney liner as this will ease the connection to the
appliance once it is pushed into the fireplace opening. 2. Open the appliance
loading door and remove the bypass shield (Fig. 9) using a 7/16″ wrench and
set it aside. 3. Open the bypass door (refer to “OPERATING INSTRUCTIONS”
section) in order to gain access to reach up through the appliance to grab
hanging flue collar assembly. 4. Pull the flue collar assembly down to align
the bolts with the through holes in the rear of the firebox then pull forward.
Note: Ensure the underside of the flue collar assembly is sliding along the
top side of the firebox as the gasket of the flue collar assembly must be
properly seated to ensure a good seal. FEEL THE AREA WHERE THE FLUE COLLAR

YOUR FIRST FIRE! The following pages contain information on the operation of
the major components on your Blaze King appliance. Please take the time to
read through this section as it will give you a better understanding of how
your appliance works. This understanding will help you to operate your
appliance at its optimum level thus extended its life while allowing you to
get the highest efficiencies from your heater.
INTRODUCTION All Blaze King free standing wood burning appliances are designed
as radiant room space heaters. They have been tested and certified to be
installed in insulated, habitable rooms within your dwelling. The appliance
has not been designed to be installed in a concrete, uninsulated basement or
in a shop/garage environment. Such applications may cause the thermostat to be
unresponsive due the constant call for heat resulting in appliance being in a
constant over fire situation. Consequential damage from this type of operation
will deem the warranty null and void.
All Blaze King wood appliances are designed to burn cord wood only.
Dimensional timber off cuts, very low moisture content small diameter wood and
pressed wood logs, when used in excess, may result in excessive internal
firebox temperatures that can cause causing irreversible damage to the
firebox’s internal structure. Excessive temperatures can be caused by many
small pieces of very low moisture content wood being used as a primary fuel
source. This may be evident by warping or warped internal plates and
retainers, possible cracking of the outer firebox and possibly premature
failure of the catalytic combustor. All wood appliances should be cleaned out
and inspected at the end of every burning season to identify if any internal
components have been affected during the burning season. If problems are
observed steps must be taken to identify and correct the problem before the
subsequent burning season. Failure to do so will result in the warranty of the
product being null and void.
EFFICIENCY Efficiency 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, does not take the water moisture into account).
Annual Fuel Utilization Efficiency (AFUE) attempts to represent the actual,
season long, average efficiency of an appliance. HHV is the actual, calculated
average efficiency obtained under test conditions. Using correctly seasoned
wood is important when trying to gain efficiency. The more seasoned (dry) the
wood, the higher the efficiency (less energy wasted on eliminating moisture
during combustion). Operating your Blaze King at lower settings will result in
higher efficiencies as the fuel will undergo a more complete combustion. For
maximum efficiency, the appliance should be installed in a location that
provides adequate intake/combustion air as well as a location that will allow
for the straightest run of optimal chimney length to establish necessary
draft.
FAN OPERATION Fans are an optional item for most Blaze King appliances. If
fans are installed on your appliance, they should be turned off until the
stove reaches normal operating temperatures. Approximately 30 minutes after a
fire has been established within the appliance, the fan speed should match the
thermostat control setting. (i.e. if your themostat is set to a medium heat
output then your fan should also be set at medium, low–low, high–high etc.).
We recommend the use of fans on all of our wood appliances. The fan system
recirculates room air over the hot surfaces of your appliance and helps spread
this super heated air around your home.

SELECTING WOOD It takes a great deal of energy to evaporate the moisture contained in green or wet wood and that energy will not be heating your home. Green or wet wood will also greatly increase creosote issues. To ensure that your wood fuel has a moisture content of 20% or lower, only use seasoned wood that has been split, stacked, and protected from rain or snow for at least 24 months. Firewood should be split and stacked in a manner that allows for air flow to all areas. Both hardwood and softwood burn equally well in this appliance, but the more dense hardwood will weigh more per cord and burn a little slower and longer. Never burn salt-water driftwood as it is very corrosive and will deteriorate the structure of the appliance. The burning of salt-water driftwood will void the warranty. The only way to accurately determine wood moisture is to purchase and measure with a moisture meter.
THIS APPLIANCE IS DESIGNED TO BURN NATURAL WOOD ONLY. DO NOT BURN WET
UNSEASONED WOOD. DOING SO CAN CAUSE EXCESSIVE CREOSOTE ACCUMULATION AND IF
IGNITED, CAN CAUSE A CHIMNEY FIRE THAT MAY RESULT IN A HOUSE FIRE CAUSING
SERIOUS BODILY HARM. BURNING AIR DRIED SEASONED WOOD WILL REDUCE THE RISK OF
CHIMNEY FIRES AND YIELD
HIGHER EFFICIENCIES AND LOWER EMISSIONS.
HOW TO USE MOISTURE METERS 1. Randomly select three logs from your wood pile
and split each one
down the middle. 2. Three points of measurement are required to determine the
moisture content of each log: 2″ (5 cm) from either end and in the middle of
the split surface of the log. To take these measurements, insert the moisture
meter pins at the points described, keeping the pins in line with the wood
grain. Record each measurement. 3. Do this to all three logs and take an
average of the readings (this is an approximate indication).
2″ / 5 cm
2″ / 5 cm
DO NOT BURN TREATED WOOD, COAL, CHARCOAL, COLORED PAPER, CARDBOARD, SOLVENTS
OR GARBAGE. BURNING THESE MATERIALS MAY RESULT IN THE RELEASE OF TOXIC FUMES
AND/OR CARBON MONOXIDE WHICH MAY RESULT IN POISONING. DO NOT BURN GARBAGE OR
FLAMMABLE FLUIDS SUCH AS GASOLINE, NAPHTHA, OR ENGINE GEL. DO NOT USE
CHEMICALS OR FLUIDS SUCH AS GASOLINE TYPE LANTERN FUEL, KEROSENE, OR CHARCOAL
LIGHTER FLUID TO START OR FRESHEN UP A FIRE IN THIS APPLIANCE. DOING SO MAY
LEAD TO OVER FIRING RESULTING IN
A HOUSE FIRE AND SERIOUS BODILY HARM.
FIRE POKER The steel Fire Poker that is provided with this appliance serves
two purposes: 1) to manipulate fuel loads and 2) to remove the ash plug via
hook welded to the top plate (if the appliance is fitted with an ash drawer).

BYPASS DOOR & BYPASS HANDLE
This catalytic wood burning appliance is fitted with a bypass door which
allows exhaust from the fire to temporarily bypass the catalytic combustor.
The bypass door is located inside the dome of the firebox at the top of the
appliance. To open the bypass door, use the bypass handle to grab the side of
the bypass latch
(Fig. A) to pull the rod outward. To close, position the bypass handle on the
center of the bypasss latch (Fig. B) and push inward.
DO NOT TOUCH THE BYPASS LATCH DIRECTLY AS DIRECT CONTACT MAY CAUSE SERIOUS BURNS. ALWAYS USE THE BYPASS HANDLE TO MANUVER THE BYPASS LATCH.

Fig. B
CATALYTIC THERMOMETER The catalytic thermometer is located in the lower left- hand corner of the cast surround. Its sole purpose is to indicate whether the combustor is ACTIVE or INACTIVE. It is important to ensure that the appliance is operated in the stove in the ACTIVE zone. When the thermometer reads INACTIVE it means that the combustor temperature is below 500F and is not producing a clean burn. The needle should point to 12 o’clock during normal operation. For calibration instructions refer to the “MAINTENANCE” section.
THERMOSTAT The thermostat is located below the ash lip of the appliance and is controlled by the thermostat knob which is located on the lower left side of the front cast assembly. When the knob is positioned at the HIGH setting, the appliance will operate at its highest burn rate and deliver its maximum heat output. As the knob is rotated counter clockwise the burn rate will decrease along with heat output. Burn rate is greatly influenced by location, installation, and external environment, so you may find it necessary to reposition the knob until you find the ideal setting to suit your situation. Please note that all adjustments to the thermostat should be done gradually as too rapid a change may cause the thermostat to operate improperly. The thermostat is set at the factory. DO NOT TAMPER WITH THE THERMOSTAT, this will result in a malfunctioning thermostat.

LIGHTING THE FIRE NOTE: As you heat up the appliance for the first time, the
paint will go through a curing process and will give off a strong odor coupled
with smoke. To minimize the inconvenience, burn the stove at a low temperature
setting for several hours. It is recommended to open a door or window until
the odor and smoke dissipates. You may also notice a change in color as the
paint cures, this is normal and will appear uniform after subsequent firings.
1. ENSURE ALL BRICKS ARE CORRECTLY POSITIONED INSIDE THE FIREBOX AND BUILD
THE FIRE DIRECTLY ON THE BRICK IN THE BOTTOM OF THE STOVE. DO NOT USE A GRATE.
2. Position the thermostat to the HIGH setting and turn the fan (if fitted)
OFF. 3. Open both the loading door and the bypass door. 4. Place 10 balls of
non-glossy paper towards the front of the bottom of the firebox then stack 20
pieces of
kindling on top of the paper in a crisscross fashion (leaving air gaps in
between sticks). 5. Light the fire and allow it to get a good start while
leaving the loading door cracked open (approximately
3 to 5 minutes). DO NOT LEAVE THE STOVE UNATTENDED. 6. Once the kindling is
fully on fire, place two or three medium size logs onto the fire. Keeping the
loading
door unlatched, allow the logs to catch fire (approximately 5 minutes). DO NOT
LEAVE THE STOVE UNATTENDED. 7. Once the logs are burning, latch the loading
door shut BUT keep the bypass door open. Leaving the loading door open after
the wood load has caught fire may cause premature failure of the catalytic
combustor. 8. When nearly all of the wood in the firebox is fully burning,
finish loading the appliance. Lay the wood as far back in the stove as
possible. Latch the loading door shut and observe the catalytic thermometer.
Once the needle is in the ACTIVE ZONE, close the bypass door. 9. Let the fire
burn with the thermostat at the HIGH setting for 20-30 minutes or until the
fire is well established. This ensures that the stove, catalyst, and wood load
are all stabilized at optimum operating temperatures. The temperature in the
stove and the gases entering the combustor must be raised to at least 500F
(indicated by the thermometer needle in the ACTIVE ZONE) for catalytic
activity to be initiated. 10. After 20-30 minutes or once the fire is well
established, gradually turn the thermostat down to the desired heat output
setting. Please note that if the thermostat is turned down too low too
quickly, the fire may go out or the combustor may stop working, indicated by
the thermometer needle falling into the INACTIVE ZONE. If this happens, simply
turn the thermostat back to a higher heat output setting to let the fire
reestablish itself. 11. If an optional fan kit is installed, turn the fan on
after the initial warm up period of 20-30 minutes.
Probably the least understood requirement of maintaining a good fire is that
of establishing a good base of coals or embers. A glowing hot coal bed will
help to maintain more even temperatures as well as assist in relighting the
next fuel load. Put as much wood into the appliance as needed, practice will
teach the amount of wood necessary to keep the fire going until the next
reloading time. Don’t be afraid to fill it completely if necessary. With the
Blaze King thermostat, the wood will only burn at the rate set on the
thermostat. Once the fire is established, the appliance should be left to
complete the full burn cycle. This is evident by a) only a glowing coal bed
(ember bed) remaining or b) the catalytic thermometer hovers just inside the
active zone. Following this procedure will maximize the efficiency of the
appliance as well as limit exhaust emissions and smoke spillage.

RELOADING PROCEDURE
WHEN PREPARING TO RELOAD, IF THE NEEDLE ON THE CATALYTIC THERMOMETER IS STILL
IN THE ACTIVE ZONE, FOLLOW THE PROCEDURE BELOW; IF THE NEEDLE HAS DROPPED INTO
THE INACTIVE ZONE, REFER BACK TO THE “LIGHTING THE FIRE” PROCEDURE ON THE
PREVIOUS PAGE.
It is important to note that the catalytic thermometer is simply displaying
the temperature of the catalytic combustor. It may be used as an aid when it
comes to identifying a reload point, but other factors such as lack of fuel in
the firebox or dropping room temperatures should be used as well.
1. Have your next load of wood ready before beginning. Turn the thermostat to
HIGH to ensure the remaining coal bed is active before relaoding. Wait 2
minutes for the air flow to stabilize.
2. To help minimize smoke spillage into the room, you may wish to open the
bypass door and again wait 2 minutes for the air flow to stabilize.
3. Crack open the loading door to allow ambient room air to be introduced
into the firebox, this may take a minute to stabilize.
4. Slowly open the loading door and proceed to reload the firebox. 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 (if opened) close the bypass
door immediately. Let the fire burn on the HIGH thermostat setting for 20 to
30 minutes OR until the fire 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 flame 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, simply run the stove on HIGH for approximately 30
minutes. The HIGH setting will burn off most of the deposits
Note: Our loading instructions are outlined in general terms due to the vast
array of variables that arise with each installation. Such variables include
type of wood fuel, chimney height and configuration, installation altitude,
seasonal weather conditions, and the desired heat output required. Over time
you will learn which settings are necessary to achieve optimal performance
with your specific installation.
THIS APPLIANCE IS HOT WHILE IN OPERATION. CHILDREN AND PETS MUST BE KEPT FROM
TOUCHING THE APPLIANCE WHEN IN USE. COMBUSTIBLE OBJECTS MUST BE KEPT A MINIMUM
OF 48″(1219 MM) FROM THE FRONT OF THE APPLIANCE. COMBUSTIBLE MATERIAL SUCH AS
CLOTHING OR FURNITURE PLACED TOO CLOSE TO THE APPLIANCE CAN CATCH FIRE. DO NOT
STORE WOOD WITHIN THE SPECIFIED SAFETY CLEARANCES OR WITHIN THE SPACE REQUIRED
FOR RE-FUELING AND ASH REMOVAL. FAILURE TO COMPLY MAY CAUSE SKIN BURNS OR
RESULT IN A HOUSE FIRE
CAUSING SERIOUS BODILY HARM.

OPTIMAL LOW BURN THERMOSTAT SETTING Your Blaze King appliance was tested and certified in accordance to the New Source Performace Standards for Residential Wood Heaters. During this test series, the low burn rate of the unit was determined by setting the thermostat knob to a position that yielded the lowest burn rate achievable. Considering that certification testing was conducting in a controlled laboratory environment with the appliance connected to a 15ft tall chimney, you may find that your optimal low burn thermostat setting is either above of below the certification test setting based on your location, installation, and the external environment you are operating in. If you find that you are setting your thermostat beyond the test setting, please note that if the thermostat is turned down too low the fire may go out or the combustor may stop working which is indicated by the thermometer needle falling into the INACTIVE ZONE. If this happens, simply turn the thermostat back to a higher heat output setting and let the fire reestablish itself.
TESTED LOW BURN SETTING
WOOD BURNING IN THE SHOULDER SEASON
There are a few things to consider if you choose to light a fire during the
spring or fall seasons when the outside temperature is milder, perhaps 55F to
70F (13°C to 21°C).
You may notice smoke spillage out of the loading door when it is opened during
start up or reloading. This is
caused by a lack of natural draft within the chimney system. The temperature
difference between the chimney system and the outside air causes flue gasses
to be drawn up and out of the chimney. Smaller temperature differences produce
less draft in your chimney system than larger temperature differences. This
air movement, referred to as Stack Effect, is also influenced by air density
and moisture differences. To eliminate the smoke spillage you may have to
stoke the fire for longer than usual. Once the fire warms the chimney the
draft will improve and spillage will be reduced. When operating the appliance
on a lower thermostat setting, the
resultant lower flue temperatures can cause your chimney system to cool down.
This also decreases natural draft and spillage may occur.
General Rules for burning in the shoulder season: · Run your appliance on HIGH
for 30 minutes after start up and reloading before gradually turning the
thermostat down to the desired heat output setting.
· The thermostat setting needs to be high enough to keep the catalytic
thermometer in the active zone. If the thermometer will not stay in the active
zone, turn the thermostat to a higher setting and then wait 15 minutes to
confirm that the thermometer remains in the active zone. Repeat as required.
· If your appliance is producing too much heat, try to reduce the volume of
wood fuel loads rather than turning your thermostat down. It is good burning
practice to build smaller, hotter fires on milder days in the spring and fall.
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 fire. In
such weather, burn the appliance for 5 to 10 minutes with the thermostat set
to HIGH to melt any possible ice build.

CATALYTIC COMBUSTOR
Page 23
DO NOT OPERATE THIS APPLIANCE WITHOUT THE CATALYTIC COMBUSTOR INSTALLED. DOING
SO WILL LEAD TO EXCESSIVE SMOKE AND TEMPERATURES THAT COULD RESULT IN A HOUSE
FIRE CAUSING SERIOUS BODILY HARM. ONLY BURN SEASONED WOOD. FAILURE TO DO SO
MAY DAMAGE THE COMBUSTOR AND WILL VOID ALL WARRANTIES.
COMBUSTOR MONITORING It is good practice to monitor the catalytic combustor to
ensure it is functioning properly. An improperly functioning combustor will
result in a loss of heating efficiency and an increase in emissions and
creosote buildup. The following list of items 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. Please refer to the “COMBUSTOR TROUBLESHOOTING” section. · This
appliance is equipped with a catalytic thermometer to monitor combustor
operation. A properly functioning combustor will maintain temperatures in
excess of 500F (indicated by the thermometer needle in the ACTIVE zone) and
often reach temperatures in excess of 1000F. If the combustor temperature
falls below 500F (thermometer needle in the INACTIVE zone), refer to the
“COMBUSTOR TESTING” section. · A good way to determine whether the combustor
is functioning properly is by comparing the amount of smoke exiting the
chimney while the combustor is engaged (bypass door closed) versus when the
combustor is bypassed (bypass door open). Note: After opening the bypass door,
wait approximately 15 minutes before observing the smoke exiting the chimney.
Significantly more smoke SHOULD be seen when the exhaust is not routed through
the combustor (bypass mode). Smoke may be visible shortly after lighting the
fire and shortly after reloading the fire so allow 20 to 30 minutes for the
fire to stabilize before making observations.
COMBUSTOR TESTING Follow these instructions to test the catalytic combustor:
- Light a fire per the “LIGHTING THE FIRE” instructions. 2. After burning a
well established fire for 1 hour, position the thermostat knob to a medium-low
burn rate
setting. 3. After 5 minutes at the lower burn rate, observe the location of the thermometer needle. A properly
functioning combustor will have a temperature greater than 500F with the thermometer needle in the ACTIVE zone. An improperly functioning combustor will yield thermometer reading in the INACTIVE zone. 4. Repeat step 3 for at least 3 burn cycles. 5. If the thermometer needled is still not reaching the ACTIVE zone, your combustor may require cleaning. 6. If, after cleaning the combustor and reburning, the thermometer needle is still not reaching the ACTIVE zone, your combustor may need replacing. Contact your Blaze King dealer for a replacement combustor. Note – It is also possible that the catalytic thermometer itself may not be functioning properly. Before deeming the combustor “disfunctional”, please refer to the “CATALYTIC THERMOMETER” section.

DO NOT PERFORM ANY CLEANING UNTIL THE FIRE IS OUT AND THE APPLIANCE IS COOL.
HOT ASH IN A VACUUM CLEANER BAG COULD MELT THE VACUUM AND COULD RESULT IN A
HOUSE FIRE
CAUSING SERIOUS BODILY HARM.
COMBUSTOR CLEANING Under certain conditions, ash particles may become attached
to the face of the combustor. These particles may be seen while the combustor
is glowing under fire or when the fire is out. Any deposits on the face of the
combustor should be removed. There are two ways to clean the face of the
combustor: (1) Brushing the combustor with a soft bristle paint brush, or (2)
Passing a vacuum cleaner wand or brush near the face of the combustor. Limit
cleaning to the face of the combustor (note – the flame shield will have to be
removed to gain access to the face). Do not scrape the combustor with any hard
tool or brush and do not run pipe cleaner through the individual cells of the
combustor as this may do more harm than good. Do not remove the combustor
during this process. Note – simply burning a hot fire usually proves to be the
best method of cleaning the combustor of deposits.
COMBUSTOR REPLACEMENT If the catalytic combustor has been deemed
“disfunctional” per the guidelines in “COMBUSTOR TESTING”, discontinue use of
the appliance until the combustor is replaced. Follow the steps below to
complete the replacement (BLAZE KING RECOMMENDS THAT YOUR DEALER OR CERTIFIED
INSTALLER PERFORM THIS PROCEDURE):
1. The appliance must be cool to touch, having gone at least 12 hours without
being burned. A combustor can reach 1400F and hold temperatures for several
hours, even after the fire is out. After waiting 12 hours, begin by removing
the flame shield by simply lifting the shield off the two tabs at either lower
corner. Pay particular attention to orientation of the flame shield in order
to reinstall in the correct position.
180-AF25 v2.01
2. Once the flame shield is removed, you will have access to the combustor.
The combustor can be made of different materials such as cordierite, mulite,
or 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 (please refer to
the “COMBUSTOR CLEANING” section).

3. There are metal tabs across the bottom and on either side of the
combustor. Using a flat blade screwdriver or pocket knife blade, slide the tip
in between the metal tab on the left side of the combustor and the steel dome
of the stove (the dome is the housing that encases the combustor). Apply
slight pressure until the combustor begins to move forward. Repeat the process
on the metal tab on the right side of the combustor. By working back and forth
the combustor will work free of the dome housing. It is normal for the gasket
that is wrapped around the combustor to fall apart during this process. New
combustors are shipped with a new gasket.
5. The new combustor will already be wrapped in gasket. Note the 1″ wide
masking tape – this will help to keep the leading edge of the gasket from
snagging during installation. If you intend to reuse you original combustor,
wrap the combustor gasket as you see here and use the 1″ masking tape around
the front and rear perimeter. During the first fire the masking tape will burn
off and the combustor gasket will swell to provide a tight seal. This seal
ensures optimal efficiency and performance. Do not burn the appliance without
the combustor gasket installed.
6. Before installing, align the combustor within the opening of the dome housing. Slowly push the combustor in at the top and apply even pressure to the left and right corners. This will allow for a better view of the bottom edge for the final fitting. DO NOT FORCE THE COMBUSTOR INTO THE OPENING. TAKE YOUR TIME AND WORK IT INTO PLACE SLOWLY.

7. Once the combustor is fully reinserted into the opening of the dome
housing, replace the flame shield. Note the flame shield sides are shaped like
a triangle. The point of the triangle should
face down to install correctly. Do not operate your appliance without the
flame shield in place. The flame shield protects the face of the combustor
against direct flame impingement and potential collisions when loading fuel.
8. When correctly installed, the flame shield will rest on the two tabs
located on the dome guard and will lean slightly forward. Now that the
combustor and flame shield have been properly reinstalled, the appliance can
be relit.
A few reminders, do not burn anything other than dry, seasoned cordwood.
Burning other materials may contaminate or ruin your new combustor. Also,
remember to keep your firebox door gasket seal properly adjusted (please refer
to the “LOADING DOOR TENSION ADJUSTMENT” section). Doing so will ensure
optimal performance of both the appliance and the combustor.

CATALYTIC COMBUSTOR
COMBUSTOR TROUBLESHOOTING PROBLEM: CREOSOTE PLUGGING
Possible Cause: The combustor is coated with creosote burning material that
produces substantial char and fly-ash. Solution: Only burn dry, seasoned wood.
Do not burn materials such as garbage, gift wrap, or cardboard.
Possible Cause: Burning wet, pitchy wood or burning large amounts of small
diameter wood with the bypass door closed without the catalytic thermometer
needle in the ACTIVE zone. Solution: Burn dry, seasoned wood and do not close
the bypass door until temperatures are high enough to initiate catalyst
lightoff (indicated by the catalytic thermometer needle in the ACTIVE zone).
Possible Cause: Combustor not functioning. Solution: If proper burning
procedures have been followed and this problem persists, replace the combustor
with an OEM Blaze King combustor (failure to do so will void your warranty).
Page 27
PROBLEM: COMBUSTOR PEELING
Possible Cause: Over firing and flame impingement can yield extreme
temperatures (above 1800F/1000°C) at combustor surface and can cause peeling.
Solution: Avoid extreme temperatures by adjusting size of fuel loads. If
peeling is severe, replace combustor.
The images to the right are examples of minor peeling (does not affect proper
combustor function) and severe peeling (closed or plugged combustor that needs
replacement). PROBLEM: CATALYTIC DEACTIVATION
Possible Cause: Burning improper fuels (ie. garbage, pressuretreated lumber,
painted wood, etc.). Solution: Burn good quality, dry, seasoned wood. If
proper burning procedures have been followed and this problem persists,
replace the combustor with an OEM Blaze King combustor (failure to do so will
void your warranty).

CATALYTIC COMBUSTOR
PROBLEM: COMBUSTOR MASKING
Possible Cause: The combustor is coated with a layer of fly-ash or soot from
burning material that produces substantial char and fly-ash. Solution: When
the appliance is cool to touch, clean the front face of the combustor with a
soft-bristled brush or vacuum lightly (refer to COMBUSTOR CLEANING for proper
procedure).
PROBLEM: THERMAL CRACKING
Possible Cause: Extreme temperature fluctuations (ie. opening loading door
while the combustor is in the ACTIVE zone) can cause thermal shock which can
lead to cracking. Solution: Avoid flooding a hot, active combustor with cool
room air when reloading.
If cracking causes large pieces of the combustor to separate, replace the
combustor with an OEM Blaze King combustor (failure to do so will void your
warranty).
PROBLEM: MECHANICAL CRACKING
Possible Cause: Mishandling the combustor or operating the appliance without
the proper gasket installed. Solution: Handle with care. Ensure combustor is
wrapped with gasket upon reinstallation.
Possible Cause: Distortion of surrounding dome housing. Solution: The
combustor should slide in and out of the dome housing with relative ease. If
this is not the case, contact your dealer for further inspection.
PROBLEM: COMBUSTOR CRUMBLING
Possible Cause: Excess air leaking into the firebox. Solution: Ensure tight
seal at loading door (see MAINTENANCE for instruction on gasket inspection).
Possible Cause: Excessive chimney draft. Solution: Use a monometer to check
and ensure chimney draft is within manufacturer specifications. Adjusting the
appliance thermostat can help regulate chimney draft.

TO PREVENT SERIOUS BURNS, DO NOT PERFORM ANY MAINTENANCE UNTIL THE APPLIANCE
IS COOL. APPLIANCE SURFACES, INCLUDING THE GLASS AND ANY ATTACHED COMPONENT,
WILL
REMAIN HOT FOR EXTENDED PERIODS OF TIME AFTER THE FIRE HAS BEEN PUT OUT.
RECOMMENDED MAINTENANCE It is strongly recommended to complete the following
tasks on a regular basis throughout the heating season: 1. Visually inspect
Catalytic Combustor and clean as required (see “COMBUSTOR CLEANING”) 2. Clean
behind internal baffles (where applicable) and inspect metal components for
warping/distortion. 3. Check Thermostat for proper function. 4. Check Fan
Assemblies for proper operation. 5. Remove all ash from firebox and ash drawer
after final burn of season. 6. Check all gaskets for proper seal and adjust as
required. 7. Inspect and clean the Venting System.
THERMOSTAT MAINTENANCE Any thermostat maintenance must be completed by a
certified installer. If the thermostat malfunctions, contact your dealer for
replacement.
OPTIONAL FAN ASSEMBLY MAINTENANCE Fan assemblies should be inspected at the
beginning of each burn season to ensure they are free from debris such as ash,
dust, pet dander, lint, etc. The accumulation of such debris could prevent the
fan blades/blower wheels from rotating freely and put excessive strain on the
fan motors, ultimately leading to failure.
ASH REMOVAL Ashes should be removed any time they come within one inch of the
door opening, though it is not advisable to completely remove all of the ashes
as wood burns best on a bed of ashes around 1/2″ thick. When removing ashes,
ensure the fire is out and the appliance is cool to touch. Ashes should be
placed in a metal container with a tight fitting lid. The closed container of
ashes should be placed on a noncombustible floor or on the ground (outside),
well away from all combustible materials, while awaiting final 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. Do not place other waste 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 TENSION ADJUSTMENT 1. Open the loading door to gain access to the
latch catch on the right side of the firebox. (Fig. 10) 2. Use a 7/16″ wrench
to loosen the two flange nuts on the latch catch. 3. Push the latch catch
backwards to increase tension. 4. Retighten the latch catch flange nuts and
perform a paper test (see “DOOR GASKET PAPER TEST”). 5. Once satisfied with
the adjusted tension, reinstall all removed components.

DO NOT OPERATE THIS APPLIANCE WITH THE LOADING DOOR UNINSTALLED OR LEFT OPEN.
DOING SO MAY LEAD TO A RUN AWAY FIRE RESULTING IN PROPERTY DAMAGE.
LOADING DOOR GASKET INSPECTION Inspect the loading door gasket for physical
deterioration, missing sections, or obvious leakage. The appliance door flange
should make a groove in the gasket material. The side of the gasket on the
inside of the groove will be dark or black while the outer side will be light
or white. Dark smudges on the outer side of the gasket may indicate an air
leak. If the groove in the gasket is very shallow 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 a need for replacement. Any time a piece of
gasket is missing or broken the entire gasket must be replaced. A way to
physically check if the gasket needs replacing is by performing a paper test
(see “DOOR GASKET PAPER TEST”).
LOADING DOOR GASKET REPLACEMENT If door gasket replacement is required, only
replace with OEM door gasket ordered through your Blaze King dealer. This
gasket will be properly sized and ready to install. Do not stretch or cut the
gasket at any time during this installation. Ensure only high temperature
silicone adhesive is used for this installation (do not use household silicone
caulking). Blaze King recommends that your dealer perform this task:
1. Ensure the fire is out and the appliance is cooled to touch before
removing the loading door. 2. Use a pair of pliers to pull the old door gasket
out of the channel and dispose of it. 3. Clean the gasket channel of any
residual adhesive to ensure the new adhesive will adhere sufficiently. 4. To
ensure proper fit, dry fit the new gasket by distributing it evenly around the
frame and then remove. 5. Run a small bead of a high temperature silicone
adhesive along the center of the gasket channel. 6. Starting in the lower
right corner, insert the new gasket into the gasket channel. Be sure to
distribute
the gasket evenly around the entire channel frame. 7. Allow the adhesive to
dry for at least 1 hour before reinstalling and closing the loading door. 8.
Confirm proper gasket installation by performing a paper test (see “DOOR
GASKET PAPER TEST”).
DO NOT OPERATE THIS APPLIANCE IF THE DOOR GASKET IS MISSING OR DAMAGED. OVER-
FIRING MAY OCCUR WHICH CAN CAUSE DAMAGE TO THE APPLIANCE OR IGNITE CREOSOTE IN
THE CHIMNEY WHICH
COULD LEAD TO A HOUSE FIRE CAUSING SERIOUS BODILY HARM.

DOOR GASKET PAPER TEST Perform this test when inspecting or replacing loading
door gasket:
1. Ensure the fire is out and the appliance is cooled to touch. 2. Insert a
piece of paper (ie. a dollar bill) into the door opening and then latch the
door shut. 3. Pull the paper out of the door while noting any obvious
resistance when doing so. 4. If no resistance is felt, adjust the door tension
(see “LOADING DOOR TENSION ADJUSTMENT”). 5. Repeat this process around the
perimeter of the door until consistent resistance is achieved.
DOOR GLASS GASKET INSPECTION To inspect the door glass gasket:
1. Ensure the fire is out and the appliance is cooled to touch. 2. Hold the
glass by placing the palm of each hand on either side and try to move it; If
the glass moves:
a. Inspect the glass retainers and ensure the screws holding the retainers in
place are tight (hand tight plus 1/4 turn). If loose, retighten, but do not
over tighten. b. Inspect the door glass gasket. If the gasket is frayed or
missing sections, replace the gasket.
REFRAIN FROM STRIKING THE GLASS OR SLAMMING THE DOOR SHUT. DO NOT OPERATE THIS
APPLIANCE IF THE DOOR GLASS OR GASKET SEAL IS BROKEN. DOING SO MAY LEAD TO A
RUN AWAY
FIRE WHICH COULD RESULT IN PROPERTY DAMAGE.
DOOR GLASS GASKET REPLACEMENT If door glass gasket replacement is required,
only replace with OEM door glass gasket ordered through your Blaze King
dealer. The OEM gasket will be ordered to size and ready to re-install. Do not
stretch or cut the gasket at any time during this installation. Blaze King
recommends that your dealer perform this task:
1. Ensure the fire is out and the appliance is cooled to touch. 2. Remove the
old glass gasket. 3. Starting at the corner opposite of the “Blaze King” logo,
carefully wrap the gasket around the edges of the door glass, pressing firmly
onto the sides of the glass with the gasket centered on the edge. Finish the
wrapping with a 1/2″ overlap. Ensure the thickness of the gasket remains
consistent and uniform. 4. Reposition the glass onto the door and then install
the glass retainers with original fasteners. Ensure the glass is parallel to
the frame and tighten the fasteners (hand tight plus 1/4 turn).
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 AND 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 difficult to remove.

BYPASS DOOR GASKET INSPECTION This can be a difficult item to inspect, but to
do so would be to visually note the amount of smoke exiting the chimney while
the bypass door is both OPEN and CLOSED. There should be significantly less
smoke when the door is in the CLOSED position. If this is not the case, the
bypass gasket may need to be replaced. Note: This inspection could also yield
a dead combustor, see “COMBUSTOR MONITORING”.
BYPASS DOOR GASKET RETAINER REPLACEMENT 1. Remove flame shield, combustor, and
smoke baffle from dome (see “CATALYTIC COMBUSTOR REPLACEMENT”). 2. Open the
bypass door and use a 7/16″ socket to unfasten the bolt and washer that holds
the bypass door to the bypass rod bracket. Once loose, remove the bypass door
through the combustor opening.

VENTING SYSTEM MAINTENANCE The entire chimney system must be cleaned and
inspected regularly, especially during the coldest months of the burn season.
The most efficient method to clean the chimney is to “sweep” it 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. Ensure the bypass door is OPEN prior to chimney cleaning so soot and
creosote fall into the firebox. Once cleaned, inspect the chimney for any
possible damage. If damage is present, the chimney section in question must be
replaced.
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 flue of a slow burning
fire and when ignited, make an extremely hot fire. Be aware that the hotter
the fire, the less creosote is deposited. The flue pipe and chimney should be
inspected regularly during the heating season, until a safe frequency for
cleaning is established to determine if a creosote build up has occurred. If
creosote accumulation is excessive, cleaning is required. It is recommended
that a professional chimney sweep does the cleaning. Both the chimney and the
appliance have to be cleaned at least once a year or as often as necessary.
A CHIMNEY FIRE CAN PERMANENTLY DAMAGE YOUR VENTING SYSTEM, WHICH CAN ONLY BE
REPAIRED BY REPLACING THE DAMAGED COMPONENTS. FAILURE TO REPAIR COULD LEAD TO
FURTHER
PROPERTY DAMAGE. DAMAGE FROM A CHIMNEY FIRE IS NOT COVERED BY THE LIMITED
WARRANTY.
RUN-AWAY OR CHIMNEY FIRE 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 fire the appliance by leaving
the door open too long after the initial start-up. 3. Replace worn, dried out
(inflexible) gaskets. 4. Have your chimney cleaned regularly. WHAT TO DO IF A
RUN-AWAY OR CHIMNEY FIRE STARTS: 1. Close the thermostat by rotating the knob
fully counter clockwise and ensure the firebox door is closed. 2. Call the
local fire department. 3. Examine the chimney, attic, and roof of the house to
see if any part has become hot enough to catch fire. If necessary, hose area
down with a fire extinguisher or water from a garden hose. 4. Do not operate
the appliance again until you are certain the chimney has not been damaged

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 fire are:
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 firm.
Considering all of the above, number one is the most important for safe and
efficient operation of any wood stove. Please study the operation instructions
carefully. Consult your BLAZE KING dealer if you have any questions not
answered in
this manual.
All of the six above mentioned needs are interrelated. A deficiency in any one
will affect 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
SOLUTION Turn the thermostat to lowest setting, check loading door to be sure it is tightly closed. Call Fire Department.
After the fire is out, have your chimney and flue connector inspected by a certified 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 flue connector should be corrected before the system is used again.
Possible causes of a chimney fire, and remedies for those causes, can be found further in this section: “Excessive Creosote Formation”, and “Spots of Creosote Accumulation in Chimney or Flue Pipe”.

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 first half of the burn
cycle, causes the fire 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.
PROBLEM: Smoke spills from door opening when loading fuel
