LOCATION FURNACE
The Apex CBT is intended to be installed in a basement, the Apex is NOT approved for acounter flow installation. Ceiling height of the furnace room needs to be a minimum of
6’ 6”(1.98 M). Hot air Plenum and Ductwork can only run Horizontally or Up,

NEVER down.
The APEX CBT can be located on either side of the alternate furnace. Minimum size of the interconnect duct is 12 in. x 17 in. Typical installations see fig. 3.
The interconnect duct opening can be cut on either side of the Apex CBT, depending where
the existing or alternate furnace is located. Cut the opening max. 1 1/2 inches from the floor
and locate close to the front, about 8” (Distance A, see fig. 4 ).The side panel can be taken offor easier cutting.
Note the bypass handle is located on the left side of the Apex, but can be moved to the rightside, this might be required in some installations to clear return air plenum or counter flow existing or alternate furnace. See page 14 for instructions.

Page 13INSTALLATION INSTRUCTIONS
Apex CBT as independent furnace:
When the blower is installed on the left side of the Apex CBT, the bypass handle needs to be moved to
the right side (see page 14), so if possible, install the blower on the right side.
Install the blower more to the front of the unit as that is where most of the heat is. When using the
VB1000 blower cut an opening 13 1/4” W x 11 13/16” H in the side panel about 9” from the front(Distance A, see fig. 4 ). Check the height of the hole with the blower. The side panel can be taken off, it
might be easier to cut the opening that way.
NOTE: After interconnect duct opening has been cut into the side of the Apex CBT, insulation must be
fastened back to the furnace cabinet all around the opening. Use the metal strips provided to hold theinsulation tightly against the cabinet inside. This will prevent the insulation from dislodging due to blower
induced vibration. (see fig.5 below)

ALTERNATE FURNACE MAY OVERHEAT, CAUSING THE CENTRAL FURNACE TO
OPERATE OTHER THAN INTENDED.

COMBUSTION AIR
Insure 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 basement
room where the furnace is located.

Page 14INSTALLATION INSTRUCTIONSMOVE BYPASS HANDLE SYSTEM FROM LEFT TO RIGHT SIDE FURNACE
In some installations it is necessary to move the bypass handle system from the left (default) to the rightside of the furnace. This is possible by unbolting the system on the left and reinstall on the right (Theround plate on the right makes place for the bypass handle but need to be installed on the left after thechange-over) Make sure to adjust the handle position and latch so proper seal is achieved on bypass
door. Reroute wiring. Fig. 7 shows the correct mounting of the handle latches when moved to right side.

Fig. 7

PRESSURE LOSS
Before any changes are made to the existing furnace system you must establish the working parametersof that system. You can then insure that addition of the add-on has not degraded the operation of theoriginal system, and correct air flow will be maintained. Change all filters in the system to insure
maximum free air flow. Using an accurate manometer check the static pressure at the end of a typicalduct near the exit to the house. Check the static pressure in the plenum above the existing furnace also.
Pressure drop = Static pressure at furnace -(minus) static pressure at duct exit
Record the pressure drop of the original system.
Addition of the add-on furnace will add airflow resistance in the system. After installation is complete
measure the pressure drop in the same run measured before add-on installation. If the air flow has
diminished the blower speed should be adjusted to compensate. When using a belted blower the pulley
size should be changed or adjusted to speed up the blower. If the pulley size is adjusted measure theblower motor current to insure that it is still within the motor plate specification. It may be necessary toreplace the motor with a more powerful motor. If a direct drive blower is used change to a higher motor
speed. Do not change the blower size.

DRAFT
Draft is created by the heated air rising in the chimney system. This draft will pull fresh combustion air
into the firebox. Recommended draft is .05 in. w.c at high fire. Too little draft results in a sluggish fireand smoking when the furnace door is opened. Too much draft (over 0.06 in. w.c.) makes it unsafe tooperate the furnace. Use a barometric control if necessary to avoid excessive draft.
DO NOT OPERATE THE APEX WITH A DRAFT OF OVER .06 INCHES WATER COLUMN. HIGHER
DRAFT LEVELS MAY CAUSE THE FIRE TO BURN OUT OF CONTROL AND CREATE A FIRE
HAZARD.
VENTING SYSTEMS
The venting system consists of a flue pipe and a chimney. These get extremely hot during use.
Temperatures inside the chimney may exceed 2000 degrees in the event of a creosote fire. To protect
against the possibility of a house fire, the flue pipe and chimney must be properly installed andmaintained. A listed thimble must be used when a connection is made through a combustible wall to achimney. A chimney support package must be used when a connection is made through the ceiling toa listed prefabricated chimney. These accessories are absolutely necessary to provide safe
clearances to combustible wall and ceiling material.
This furnace may be connected to a lined masonry chimney or a listed factory built chimney suitablefor use with solid fuels and conforming to, ULC629 in Canada or UL-103HT in the USA. Do notconnect it to a chimney serving another appliance. To do so will affect the safe operation of both
appliances, and will void the furnace warranty. You must comply with the local authority having
jurisdiction and/or in Canada, CSA installation standard B365-M87.
The flue pipe must be 7” diameter, 24/26 MSG Back/Blue steel. Do not use aluminum or galvanizedsteel. They cannot properly withstand the extreme temperatures of a wood fire. The flue pipe between
the furnace and the chimney should be as short and direct as possible. Blaze King recommends theuse of double wall pipe and two 45° elbows instead of a single 90° elbow. A minimum 36” rise isrecommended prior to any elbows being used.
The flue pipe must be attached to either an approved masonry chimney or one of the listed factorybuilt chimneys suitable for use with solid wood fuel. All joints must be tight and fastened with sheet
metal screws.
WARNING: The flue pipe is to be used only within the room, between the furnace and ceiling/wall. Never use a flue pipe to pass through a combustible ceiling or wall. Always maintain theminimum clearances to combustibles as required by the applicable building codes.
Version 1.04
March 2011www.blazeking.com

APEX cbt

Page 16INSTALLATION INSTRUCTIONS - VENTING
Flue pipe sections must be attached to the furnace andto each other with the crimped end toward the furnace(Fig. 8). This allows creosote to run into the furnace andnot onto the outside of the pipe. All joints should besecured with three metal screws. Otherwise, in theevent of a creosote fire, the connection may vibrateapart. Horizontal lengths of flue pipe should have an
upward slope from the furnace of 1/4 inch per foot.

Fig.8 Flue Gas Direction

CONNECTION TO A MASONRY CHIMNEY
Should the furnace be connected to a masonry chimney, the chimney should be examined for cracks, loose
mortar, other signs of deterioration, and blockage. The furnace should not be installed until it is determinedthat the chimney is safe for use. Since an oversized flue contributes to the accumulation of creosote, thesize of the flue should be checked to determine that it is not too large for the furnace. For this furnace it isrecommended that the flue size should not exceed the overall area of a 7” flue (38.5 square inches). The
chimney should also be checked to assure it meets the minimum standards of the National Fire Protection
Association (NFPA) Standard 211. Following is a list of the more critical minimum requirements for aproperly constructed chimney.
1. The masonry wall of the chimney, if brick or modular block, must be a minimum of 4 inches nominal
thickness. A mountain or rubble stone wall must be at least 12 inches thick.
2. The chimney must have a fire clay flue liner (or equivalent) with a minimum thickness of 5/8 inch andmust be installed with refractory mortar. There must be at least 1/2-inch air space between the flue liner
and the chimney wall (Fig. 9). An equivalent liner might be a listed chimney liner system or otherapproved material.
3. A chimney inside the house must have at least 2 inches of clearance to the combustible structure. A
chimney outside the house must have at least one-inch clearance to the combustible structure. Fire
stops must be installed at the spaces where the chimney passes through floors and/or ceiling (Fig. 10).
Remember that insulation must not contact the chimney. There must be air space around the chimney.
Insulation must be 2 inches or more from the chimney (Fig. 11).
4. A chimney must be the required height above the roof or other obstruction for safety and for proper draft
operation. The requirement is that the chimney must be at least 3 feet higher than the highest point
where it passes through the roof and at least 2 feet higher than the highest part of the roof or structurethat is within 10 feet of the chimney, measured horizontally (Fig. 12).

Fig. 11 Clearances—Masonry To Combustibles

THIMBLEA thimble must be used when the connection from the furnace is madethrough a combustible wall to a masonry chimney. There are several
methods to use for connection through a combustible wall, two of which
are illustrated in this manual. Local building authorities may be consulted
or NFPA 211 may be used for additional methods of chimney
connection.
Also, listed prefabricated metal thimbles may be purchased for use withwood furnaces. The manufacturer's installation instructions for thethimbles must be strictly followed to assure the safety of the system. Be
sure to maintain the designated clearance to combustible materials.

Fig. 12 Minimum Chimney Height

BRICK CHIMNEY THIMBLE ASSEMBLY
Construction of the brick thimble assembly requires 12 inches of brick around a fire clay liner. Be sure thepoint of penetration allows an 18 inch clearance from theconnector to the ceiling. An appropriate opening for a chimney
connector must be cut in the wall to maintain the required 12
inches of brick separation from combustibles. It will benecessary to cut wall studs and install a header and sill frame tomaintain proper dimensions and to hold the weight of the brick(Fig. 13). NOTE: Whenever cutting through a wall, check firstwith local building authorities to be sure building integrity is
maintained. Minimum 3 1/2-inch (4-inch nominal) thick solid
12"
bricks are to be used. The fire clay liner (ASTM C35 orequivalent), minimum 5/8 inch wall thickness, must not
penetrate into the chimney beyond the inner surface of thechimney flue liner and must be firmly cemented in place. If it isnecessary to cut a hole in the chimney liner, use extreme care tokeep it from shattering. Refractory mortar must be used at thejunction to the chimney liner (Fig. 14). After the assembly iscomplete, insert the chimney connector in the fire clay liner. Do
not push it beyond the inside edge of the chimney liner because
this will affect the draw of the chimney.

INSTALLATION INSTRUCTIONS - VENTINGPREFABRICATED CHIMNEY WITH METAL CHIMNEY SUPPORT AS THIMBLE
For the method of installation to a masonry chimney, it will be necessary to purchase a 12-inch longsection of prefabricated listed chimney to use as a thimble. Purchase a wall spacer, trim collar and wallband that are manufactured to fit the chimney section you purchase.
The safety features of this system are: the 2-inch air space between the chimney section andcombustible wall, and the 1-inch air space around the chimney connector as it passes through thechimney section to the chimney.
The location of the opening through the wall to the chimney must leave a minimum 18 inch verticalclearance between the flue pipe and the ceiling to prevent the ceiling from catching fire.
For instructions on installation of the thimble, refer to chimney manufacturer's instructions.

If an exterior masonry chimney isused you may have draft problems
due to the chimney being too cold.
Exterior masonry chimney’s
should be lined with a listed
stainless steel liner for better
operation of these units.

INSTALLATION INSTRUCTIONS - VENTINGCONNECTION TO A METAL PREFABRICATED CHIMNEY
When a metal prefabricated chimney is used, the manufacturer's installation instructions must be followed
precisely. You must also purchase (from the same manufacturer) and install the ceiling support package
or wall pass through and "T" section package, fire stops (when needed), insulation shield, roof flashing,chimney cap, etc. Maintain the proper clearance to the structure as recommended by the manufacturer.
This clearance is usually a minimum of 2 inches, although it may vary by manufacturer or for certain
components.
There are basically two methods of metal chimney installation. One method is to install the chimney inside
the residence through the ceiling(s) and the roof. The other method is to install an exterior chimney thatruns up the outside of the residence (not recommended). If it is necessary to run the chimney outside,build an outside chase around the chimney.
The chimney must be the required height above the roof or other obstruction for safety and for proper draft
operation. The requirement is that the chimney must be at least 3 feet higher than the highest point where
it passes through the roof and at least 2 feet higher than the highest part of the roof or structure that iswithin 10 feet of the chimney, measured horizontally (Fig. 12). The height requirement is necessary in theinterest of safety and does not necessarily assure proper flue draft. Use a minimum total system height of
12 feet, measured from the furnace flue collar to the top of the chimney, not including the chimney cap.
THIMBLEWhen a wall exit installation is used, a listed assembly thimble must be installed. In a roof exit installation,
the ceiling support box supplied with the manufactured chimney acts as a thimble.
REMEMBER: Follow the manufacturer's installation instructions and maintain the manufacturer's
specified clearance distances.
Install an attic insulation shield to maintain the specified clearance to insulation. Insulation in this air space
will cause a heat buildup which may ignite the ceiling joists
The “Through The Roof” method of installation requires at a minimum a ceiling support package, anInsulation shield and roof flashing.
The “Through The Wall” method requires at a minimum a wall pass through device, a wall support
package and insulated “T” section and roof flashing.

INSTALLATION INSTRUCTIONSTHERMOSTATSYour system uses two thermostats - one to control the wood add-on and one to control the alternate furnace.
The alternate (electric, gas or oil) thermostat must be interlocked to the limit switches provided on the wood
furnace plenum (see wiring diagrams). This is to prevent the alternate furnace from operating when theplenum temperature rises above 150°F. Thermostats should be mounted side by side on an inside wall out of
direct sunlight or other heat sources.

ELECTRICAL GENERAL
All wiring on the Apex CBT shall be fastened to the outside of the insulated cabinet surfaces only. This is toprevent overheating by direct contact with firebox components.
Electrical installation must be done by a qualified licensed electrician, experienced in control circuit wiring.

FAN LIMIT INSTALLATION
Drill 2 holes into the front of the plenum 18” above unit. Using the bracket provided, install the fan limit junction
box assembly onto the furnace warm air plenum. All wiring must be routed on the outside of the cabinet
surface. Installation of wiring must be by a qualified electrician. See instructions for wiring diagrams which
apply to your specific installation (page 23-26).

OPERATION INSTRUCTIONSIn order to get peak performance out of your Blaze King furnace you will need to follow a few basic steps
outlined in the following chapters. Forget everything you learned about how to burn or operate a regularwood furnace. You cannot just throw in some newspaper and a log or two, light a match and expect yourBlaze King to work the same way an inefficient wood furnace would. Your Blaze King was designed toburn more efficiently, saving you time and money.

BYPASSAll catalytic wood burning appliances have a bypass device for allowing the smoke from the fire totemporarily bypass, or go around, the catalyst. The bypass is located inside the top front of the firebox.
The bypass is a steel plate door, hinged inside the furnace, and is controlled by the bypass handle on
the left or right side of the furnace. When the handle is lifted up, the bypass is open, when pushed down,
it is closed.
Other than during the initial startup sequence, DO NOT burn the furnace with the by-pass open. Leaving
the by-pass open may APPEAR to achieve a hotter fire, but in fact, just the opposite is true. Bypassing
the catalyst allows as much as 50% of the potential fuel - and therefore heat - to go directly up thechimney. This Blaze King catalytic furnace produces the greatest amount of heat when the by-pass is
closed, and the catalyst is active.
The bypass system also contains a built in switch which reduces the combustion air when the bypass is
opened to avoid over firing.
See page 35 for adjusting bypass handle and gasket.

CATALYTIC MONITOR (THERMOMETER)This monitor is located on the side of the furnace. It purpose is to show you the temperature of thecatalyst. Depending on the temperature you know if the catalyst is active or not. Press the red button
and the catalyst temperature will be displayed for 30 minutes. When temperature is below 500 F,“COOL” will be displayed.

FUEL
Blaze King recommends using dry seasoned wood, split and stacked and protected from rain for at least
24 months with a moisture content of 13% or lower. It takes a great deal of energy to evaporate themoisture contained in green wood and that energy will not be heating your house. Also, green or wet
wood will greatly increase creosote & combustor problems. Blaze King moisture meters are available atyour Blaze King dealer.
Our wood furnaces are not designed for burning coal and doing so will void the warranty.
Never burn salt-water driftwood. It is very corrosive and will damage the firebox. Burning salty wood also
voids the warranty.
This controlled combustion firebox has been designed for high efficiency and long burn times. The
proper time to add more wood is when the last charge has been reduced to a glowing charcoal bed.
There will be very little smoke at this stage in the burn cycle.
WARNING: BURNING WET UNSEASONED WOOD CAN CAUSE EXCESSIVE CREOSOTE
ACCUMULATION. WHEN CREOSOTE IS IGNITED IT CAN CAUSE A CHIMNEY FIRE WHICH MAY
RESULT IN A SERIOUS HOUSE FIRE.

OPERATION INSTRUCTIONSAIR SETTINGS
The high output (when there is a heat demand) is set in the factory and can not be adjusted. The low output (standby)
can be adjusted with the screw on the primary air blade (see fig 25) situated behind the draft box underneath the loading
door. It controls the gap A. The bigger the gap, the more combustion air enters into the firebox, the higher the low burn.
Every installation is different because of draft, kind of wood being used and geographic location.
Adjust the flap in a way that it maintains a fire overnight on standby but not using high amounts of wood.

A

Fig. 25 Low output adjustment
THERMOSTATS
If your furnace is operating as a combination unit remember both units will not fire at the same time. If the wood furnace
is to be your main source of heat, set the wood thermostat at your desired room temperature and set the thermostat fromyour alternate furnace approximately 5° F (3°C) lower.
Note: If the alternative furnace is running and the wood furnace is starting to heat up after (re-)loading, the alternate
furnace will shut off automatically.
When programmable thermostats are used, it is recommended that the wood thermostat is programmed so the Apex will
fire up before the alternate furnace will. This will give the Apex time to build up a hot fire again after being in standby
mode.

Page 30OPERATION INSTRUCTIONSFAN OPERATIONThe blower will be turning on and off automatically based on the heat output off the wood furnace. At 150 F in theplenum the fan will turn on and at 100 F it will turn off.
If the fan turns on regularly in standby mode (no call for heat) adjust the low output so less heat will be produced at low.

NEVER START A FIRE UNLESS ALL BRICKS ARE CORRECTLYPLACED INSIDE THE FIREBOX. CHECK THE INSTALLATION INSTRUCTIONSCAREFULLY. ALWAYS OPEN THE BYPASS DOOR BEFORE OPENING THE LOADING DOOR. ONCE
THE LOADING DOOR IS CLOSED, CLOSE THE BYPASS DOOR DIRECTLY AFTER.
BUILD A SMALL FIRE THE FIRST TIME YOU USE YOUR APEX CBT. STARTING OFF WITH A HOTINTENSE FIRE CAN DAMAGE THE CAST-LINERS.

Turn up the wall thermostat to open the draft
Open the bypass door
NEVER USE FLAMMABLE FLUIDS TO START THE FIRE
On top of crumpled paper place split dry kindling and then small wood.
Light the fire as low as possible and leave the door 1/2" (13 mm) opened.
Once the kindling is well ignited or the coals revived, load 2 or 3 fire logs in such a way that the flames
can work their way between the logs, then close the door and immediately close the bypass door after(this will supply more combustion air)After a few minutes check to see if the catalytic monitor indicates 500 F or higher, if not, repeat the lasttwo steps.
When a decent fire is going, add larger pieces of wood.
High temperature paints will give off an odor the first time you light your furnace. Open a window toensure adequate ventilation.
The damper will close when either the plenum temperature reaches the limit level or the room
temperature reaches the thermostat setting.
CAUTION: Air dampers are set in the factory, never adjust or open dampers manually to increased firing
for any reason.
The circulation blower should cycle off and on automatically, according to plenum temperature.

OPERATION DURING POWER FAILURE CONDITIONS






Your system was designed as a forced air system; do not expect regular performance without the fanrunning. Do not over fire to compensate for the lack of a fan. Your system will perform at a lower capacity
in the gravity mode.
During a power failure never fill the firebox above the top of the firebox liner bricks.
Remove the cabinet door from the blower. Remove the air filter and open all registers to facilitate free air
flow.
Lift the left manual draft control lever until it stays up. This will open the draft to a pre set level, see fig. 26
When the power returns the damper motor will open (after pressing the reset button on the limit switch)and the manual control will return to normal position. Even without the manual control open the factoryadjusted bleed air system will provide some combustion air. When power is restored reinstall the blower
system, air filters, and door.

Without the blower running, high temperature in the system builds up quickly and over firing will result inpermanent damage to the firebox. Maintain a small fire only. Over firing voids all product warranties.

MAINTENANCE
Your appliance has been manufactured in the Blaze King tradition of high quality. To ensure years of trouble
free operation, have your furnace serviced regularly by your Blaze King dealer.
Periodically during heating season thoroughly clean the chimney and firebox so your system is ready for next
fall. Inspect all firebricks and replace any damaged bricks. A broken firebrick should be replaced to prevent
warping of the firebox.
OPERATE THE ALTERNATE ELECTRIC, GAS OR OIL FURNACE PERIODICALLY TO ENSURE THAT IT
WILL OPERATE SATISFACTORILY WHEN NEEDED.
INSPECT VENT PIPES, VENT PIPE JOINTS AND VENT PIPE SEALS REGULARLY TO ENSURE THATSMOKE AND FLUE GASES ARE NOT DRAWN INTO, OR CIRCULATED BY, THE AIR CIRCULATIONSYSTEM

ASHES
Ashes should be cleaned out when they reach a depth of 4" in the firebox (half way up the lower bricks).
Disposal of Ashes - Ashes should be placed in a metal container with a tight-fitting lid. The closed containerof ashes should be placed on a noncombustible floor or on the ground, well away from all combustible
materials, pending 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.

CATALYTIC COMBUSTOR REPLACEMENT
If the combustor must be examined or replaced, follow this procedure;
1. Allow the furnace to burn out and cool down.
2. Open the door and the bypass door. Remove the flame shield underneath the combustor.
3. The combustor may now be seen. Push the combustor from underneath up into the area behind thebypass door. The combustor can now be taken out thru the bypass opening.
4. The gasket material around the stainless band will probably disintegrate as the combustor is removed. If
the combustor is placed back in the furnace, the gasket material MUST be replaced. Obtain a piece ofgasket from your dealer. When installing the gasket ensure the ends are butted closely together.
5. Do not burn the furnace with the combustor removed, or without the gasket around the combustor.
6. To replace the combustor, first clean the combustor seat and the area around it. Also take this opportunity
to clean the area around the by-pass -- use a vacuum cleaner.
7. Lift the new combustor into position, with the stainless flanges up. The combustor should easily slide into
position. Don't be concerned if it appears a bit loose. The insulation around the outside of the stainlessband will expand during the first fire and will hold the combustor in.
8. Reinstall the flame shield
For cleaning procedures for the combustor, see pages 39-41

MAINTENANCEGASKET INSPECTION
Inspect the door and bypass door gasket for physical deterioration, missing sections or obvious leakage. The furnace
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
a smoke leak. If the groove is very shallow or missing, or if there is a heavy ash or creosote deposit along the bottomedge of the gasket, it may need to be replaced. Frayed or broken gasket material, or a gasket that is hard andunyielding, will also indicate need for replacement. Any time a piece of gasket is missing or is broken anywhere, theentire gasket must be replaced.
To check the gasket further, insert a piece of paper (a dollar bill will work) into the door opening and close and latch thedoor. Obvious resistance should be felt when pulling the paper out. Repeat this check several times around theperimeter of the door.
Loading door gasket tightening instructions can be found below under point 8 and fig. 28
Bypass door adjusting can be found on page 35.
LOADING DOOR GASKET REPLACEMENT
1. If the door gasket is to be replaced, be sure you have some 7/8” fiber glass gasket material, ready to re-install. Seeyour Blaze King dealer.
2. Be sure the fire is out and the furnace has cooled down. The door does not have to be removed from the furnace.
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 fit smoothly
5. Run a small bead of a high temperature silicone adhesive (such as G.E. Silicone Sealer, or the equivalent) along thecenter of the channel. DO NOT USE HOUSEHOLD SILICONE CAULKING. High temperature silicone may beobtained from most auto parts stores.
6. Start the new gasket in the lower right corner. Do not stretch or cut the gasket. Distribute the gasket evenly aroundthe frame.
7. Close the Loading Door and allow the adhesive to dry.
8. Door adjustment: the door seal is adjusted by moving the latch catch on the furnace in or out. To do this, undo thetwo bolts (see fig.28). The gasket should be just tight enough to test ok as in step 9, do not over tighten the latch
which makes the door difficult to latch.
9. Check the fit 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 perimeterof the door.

WARNING:
DO NOT OPERATE THIS WOOD FURNACE IF THE
DOOR GASKET IS MISSING OR DAMAGED.
DANGEROUS OVERFIRING CAN OCCUR WHICHCAN DAMAGE THE APPLIANCE OR IGNITE
CREOSOTE IN THE CHIMNEY, POSSIBLY
CAUSING A HOUSE FIRE. IF ANY PART OF THE
WOODFURNACE OR FLUE SYSTEM IS GLOWINGTHE FURNACE IS BEING OVERFIRED.

MAINTENANCE
BYPASS DOOR GASKET REPLACEMENT
1. If the bypass door gasket is to be replaced, be sure you have some 7/8” fiber glass gasket material, ready to reinstall. This gasket is different then the door gasket. Both are 7/8” but the bypass door gasket is a denser material.
See your Blaze King dealer.
2. Be sure the fire is out and the furnace has cooled down. The door does not have to be removed from the furnace.
Open the bypass as far as possible for easy access.
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 fit smoothly.
5. Run a small bead of a high temperature silicone adhesive (such as G.E. Silicone Sealer, or the equivalent) along thecenter of the channel. DO NOT USE HOUSEHOLD SILICONE CAULKING. High temperature silicone may beobtained from most auto parts stores.
6. Start the new gasket in a corner. Do not stretch or cut the gasket. Distribute the gasket evenly around the channel.
7. Close the bypass door and allow the adhesive to dry.

ADJUSTING BYPASS HANDLE
The bypass handle has to be adjusted over time toachieve a good seal on the bypass door gasket. The“latch” where the bypass handle is positioned into
when closing the bypass door can be adjusted.
Undo the two bolts so the latch can be moved to therequired position.
Check the fit of the door gasket. Insert a narrow stripof paper into the bypass door opening and close
and latch the bypass door. Obvious resistanceshould be felt when pulling the paper out. Repeat
this check several times around the perimeter of the
bypass door.
When further adjustment is not possible anymore
with the latch, unbolt the handle, rotate the required
angle and tighten bolts again.

CREOSOTE
Creosote can be a problem in any wood-burning appliance. Creosote is a black, foul smelling liquid that
results from distillation of wood gases during the combustion process. It solidifies depending on temperatureand in either state is highly combustible. The best way to prevent or minimize creosote build up is to follow
proper firing methods. The amount of creosote depends on several factors that include:
1) Moisture content of the fuel2) Stack or flue temperature3) Amount of draft
4) Efficiency of the appliance5) Turbulence of smoke.
At stack temperature below 120°C (250°F), the creosote will condense out of the gasses (smoke). Once aflue pipe becomes heavily coated with creosote, the only safe way to remove it is mechanically with a properchimney cleaner or brush. A combination of wet fuel and poor operating procedure may necessitate weekly
cleaning to remove creosote buildup.
Remember - the hotter the fire the less creosote. Small intense fires create less creosote than large,
smoldering fires. We recommend that each day a small intense fire be built, preferably in the morning. This
daily practice should burn out the small deposits of creosote before they build to a dangerous level. The
combustion air inlet should be opened for at least 30 minutes by turning the thermostat up in the morning andevening. NEVER "burn out" large deposits of more than one days accumulation.
Always assure safety by having a clearly understood plan of how to handle a chimney fire, should one occur.
In conclusion, creosote can best be controlled as follows:
1.
2.
3.
4.
5.

Burning dry split wood.
Mixing small and large pieces of wood.
During warm weather using smaller split wood.
Establish a routine for the storage of fuel, care of the appliance, and firing techniques.
Keeping stack temperature up by using double wall pipe on flue runs andprotect outside chimney installations in a chase. Minimize elbows and keep
flue runs as short as possible and ensure tight connections.
6. Checking daily for creosote until experience shows how often cleaning is required. Remember aclean chimney is a safe chimney.
7. Having a clearly understood plan should a chimney fire occur.

WARNING: FAILURE TO INSPECT AND CLEAN YOUR CHIMNEYSYSTEM REGULARLY CAN RESULT IN A SERIOUS FIRE WHICH MAY DAMAGE YOURCHIMNEY OR CAUSE A HOUSE FIRE
