EPA COMPLIANCE STATUS
This manual describes the installation and operation of the New Buck Corporation, Model 20 wood heater.
This heater meets the U.S. Environmental Protection Agency’s Emission limits for wood heaters sold after July
1, 1992. Under specific test conditions this heater has been shown to deliver heat at rates ranging from
approximately 10,000 to 39,000 BTU/hr.
SAFETY STANDARD COMPLIANCE
The Model 20 catalytic solid fuel (wood) burning combination room heater/fireplace stove manufactured by
New Buck Corporation complies with UL 1482-1988:16CFR1209:UL 127 (1988): UL 1482 (2006):UL 1482
(2008):UL 1482 (2006):UL 1482 (2010) and UL 737-1995 for residential freestanding and masonry fireplace
insert installations when constructed and installed in accordance with ITS approved documentation.
CATALYST EQUIPPED
This wood heater contains a catalytic combustor, which needs periodic inspection and replacement for proper
operation. It is against the law to operate this wood heater in a manner inconsistent with operating instructions
in this manual or if the catalytic element is deactivated or removed.
CATALYST WARRANTY
The combustor supplied with this heater is a set of (2) (2x3-5/16x7x25 cells). Consult the catalytic combustor
warranty also supplied with this heater. All warranty claims should be addressed to:
Applied Ceramics
Customer Service Department
P.O. Box 29664
Atlanta, GA 30359
770-448-6888
See enclosed catalyst warranty for instructions. New Buck Corporation does not handle catalyst replacements.
Customer can order directly from Applied Ceramics.
PROPER FUEL SELECTION
This heater is designed to burn dried natural seasoned hard wood only. Higher efficiencies and lower
emissions generally result when burning air dried natural seasoned hardwoods, as compared to softwoods or to
green or freshly cut hardwoods.
DO NOT BURN:
1) Treated Wood
3) Garbage
5) Solvents
7) Trash
2) Coal
4) Cardboard
6) Colored Paper
Burning treated wood, garbage, solvents, colored paper or trash may result in release of toxic fumes and may
poison or render catalytic combustor ineffective.
Burning coal, cardboard or loose paper can produce soot or large flakes of char or fly ash that can coat
combustor, causing smoke spillage into room and rendering combustor ineffective.
ACHIEVING CATALYTIC LIGHT-OFF
The temperature in stove and gases entering combustor must be raised to between 500o F to 700o F for catalytic
activity to be initiated. This can be determined with use of a temperature monitor (TM-20). During start up of
a cold stove, a medium to high firing rate must be maintained for about 20 minutes. This ensures that stove,
catalyst and fuel are all stabilized at proper operating temperatures. Even though it is possible to have gas
temperatures reach 600o F within two to three minutes after a fire is started, if fire is allowed to die down
immediately it may go out or combustor may stop working. If this happens open damper to raise temperature
to activate catalyst. Once the combustor starts working, heat generated in it by burning smoke will keep it
working.
ACHIEVING CATALYTIC LIGHT-OFF WHEN REFUELING
During refueling and rekindling of a cool fire or a fire that has burned down to charcoal phase, operate stove at
a medium to high firing rate for about 10 minutes to ensure catalyst reaches approximately 600o F.
Page 4
CATALYST MONITORING
It is important to periodically monitor operation of catalytic combustor to ensure that it is functioning properly and
to determine when it needs to be replaced. A non-functioning combustor will result in a loss of heating efficiency
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 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 decrease in performance. If any of these conditions exist, refer to Catalyst Troubleshooting
Section of the owner’s manual.
This catalytic heater is equipped with means to install a temperature probe to monitor catalyst operation. Properly
functioning combustors typically maintain temperatures in excess of 1000o F. If catalyst temperatures are not in
excess of 500o F, refer to Catalyst Troubleshooting section of this owner’s manual. A indication of whether
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 amount of smoke leaving chimney when the smoke is not
routed through combustor (bypass mode).
Step 1—Light stove in accordance with instructions.
Step 2—With smoke routed through catalyst, go outside and observe emissions leaving
chimney.
Step 3—Engage bypass mechanism and again observe emissions leaving the chimney.
Significantly more smoke should be seen when exhaust is not routed through the combustor (bypass mode). Be
careful not to confuse smoke with steam from wet wood.
CAUTION AGAINST OVER-FIRING
Do not over-fire this heater.
Attempts to achieve heat output rates that exceed heater design specifications can result in permanent damage to
the heater and to the catalytic combustor.
MAINTAIN PROPER DRAFT
Draft is the force which moves air from appliance up through chimney. The amount of draft in your chimney
depends on length of chimney, local geography, nearby obstructions and other factors. Too much draft may cause
excessive temperatures in appliance and may damage catalytic combustor. Inadequate draft may cause backpuffing
into room and “plugging” of chimney or catalyst.
Inadequate draft will cause appliance to leak smoke into room through appliance and chimney connector joints.
An uncontrollable burn or a glowing red stove part or chimney connector indicates excessive draft.
ASH REMOVAL
CAUTION: Never remove ashes from heater with blower running.
Whenever ashes build up in firebox and when fire has burned down and cooled, remove excess ashes. Leave an
ash bed approximately 1 inch deep on firebox bottom to help maintain a hot charcoal bed.
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed
on a non-combustible floor or on ground, away from all combustible materials, pending final disposal. The ashes
should be retained in closed container until all cinders have thoroughly cooled.

SECTION II
MASONRY INSERT INSTALLATION
INSTALLATION PRECAUTIONS
Extensive field and laboratory testing has shown that catalytic stoves perform best as fireplace inserts when:
1.
A direct connect kit is used to connect the stove exhaust outlet directly to masonry flue of fireplace when flue
liner size is approximately same size as heater flue gas exit. A rain cap is also recommended to keep flue dry
thus allowing a hotter draft.
NFPA 211 CODE: The National Fire Protection Association code requires all fireplace insert heaters to be
positively connected from heater to flue liner (subject to State and Local codes in your area).
2.
3.
An equivalent sized flue liner is installed when flue liner size is larger than heater flue gas exit. Connection
must be from stove exhaust outlet extending full height of tchimney and must include a rain cap.
Location of chimney is interior (not on an outside wall).
Satisfactory results have been reported with installations other than as listed above. However, as all chimneys draw
differently, problems with performance may be encountered if steps are not taken to keep the chimney hot. A draft
between .03 and .06 inches of water column is recommended for proper catalytic operation.
Use the following to complete installation of unit as an insert : Kit #FP20

FLOOR PROTECTION
Floor protector must be 3/8" minimum thickness non-combustible material or equivalent.
How to use alternate materials and how to calculate equivalent thickness
An easy means of determining if a proposed alternate floor protector meets requirements listed
in the appliance manual is to follow this procedure:
1. Convert specification to R-value:
R-value is given—no conversion is needed.
K– factor is given with a required thickness (T) in inches:
C-factor is given: R=1/C
2. Determine the R-value of the proposed alternate floor protector.
Use the formula in step (1) to convert values not expressed as “R”
For multiple layers, add R-values of each layer to determine the overall R-value.
3. If the overall R-value of the system is greater than the R-value of the specified floor
protector, the alternate is acceptable.
Example:
The specified floor protector should be 3/4” thick material with a K-factor of 0.84.
The proposed alternate is 4” brick with a C-factor of 1.25 over 1/8” mineral board with a
K-factor of 0.29.
Step (a): Use formula above to convert specification to R-value. R= 1/K x T = 1/0.84 x .75 =
0.893
Step (b): Calculate R of proposed system. 4” brick of C=1.25, therefore Rbrick = 1/C = 1/1.25
= 0.80 1/8” mineral board of K = 0.29, therefore Rmin.bd. =1/029 x0.125 = 0.431
Step (c): Compare proposed system R of 1.231 to specified R of 0.893. Since proposed
system R is greater than required , the system is acceptable.

3. To complete methods 1 and 2:
Position heater into the Pre-Fab Fireplace and center flue exit under connector.
4. Slide connector (or slip connector) down into flue exit of heater approximately 3/8”, Check that damper
operates without hitting connector. Now, seal connector to heater (and fireplace throat if method #1 is
used) using refractory cement.
CAUTION! Do not loosen ceramic blanket.
5. CAUTION! Crimped end of connector must be placed into heater throat.
6. Check installation minimum clearances and install an approved heater extension or floor protector to
meet at least the minimum clearances.
This heater is now ready for use. Please read heater operation Section VII of this manual before burning a fire in the
heater.
Page 28
SECTION VI
WOOD HEATER SAFETY
Certain safety hazards are inherent in any wood heater installation. You should be aware of these so that a safe and
proper installation can be made.
1.
2.
FAULTY CHIMNEY: An older masonry chimney should be thoroughly checked to be sure there are no
holes or weak spots which could allow sparks or hot gases to escape.
HEAT CONDUCTION: Placing combustible materials too close to a heater or chimney can be a fire
hazard.
By keeping these particular hazards in mind as you install and use your room heater you can ensure a safe,
reliable installation.

NOTE: When burning any unit or appliance that combusts fuel for heat, such as coal, oil, wood or
natural and (L.P.) liquid petroleum gas. We highly recommend the use of smoke and carbon
monoxide detectors in your home.
SAFETY PRECAUTIONS
For your protection, read and follow these safety precautions closely.
CAUTION: NEVER use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid or similar
liquids to start or “freshen up” a fire in heater. Keep all such liquids well away from the stove when it is in use.
All fluids of this type give off volatile fumes and can and WILL EXPLODE!! Don’t take a chance with the
safety of your home and family.
WARNING: Hot while in operation. Keep children, clothing and furniture away from stove. Contact may cause
skin burns.
1.
2.
3.
4.
5.
Use a spark arresting shield (3/8” mesh) on top of chimney. Check monthly as this is a code requirement
in some areas.
Use smoke detectors around heater as well as in sleeping areas.
Keep a fire extinguisher rated for Class “A” fires near heater.
Check with your insurance company to be sure your policy covers installation and use of a wood fired
room heater.
Creosote-Formation and Need for Removal: When wood is burned slowly, it produces tar and other
organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in
relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue
lining. When ignited this creosote makes an extremely hot fire.
The connector and/or chimney should be inspected at least once a month during heating season to determine if a
creosote buildup has occurred.
If creosote has accumulated, it should be removed to reduce risk of a chimney fire.
CAUTION: Never remove ashes from your heater with blower running.
6.
7.
8.
9.
Locate furniture and any other combustibles away from the heater.
Store firewood at a safe distance from heater.
Disposal of Ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed
container of ashes should be placed on a non-combustible floor or on 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 closed container until all cinders have thoroughly cooled.
Ashes can ignite up to 72 hours after removal.
Always exercise caution when using your heater. Be particularly careful when there are children around
an operating heater.
Page 29
SECTION VII
OPERATION
This section of manual is to help you get the maximum efficiency and maximum smoke (particulate) reduction from your
heater. If you should experience any difficulty or have any questions concerning your heater, contact your dealer for
assistance. NOTE: The manufacturer recommends that for maximum performance burn natal seasoned hard wood.
Build a fire for maximum efficiency. This model burns wood and extracts heat so efficiently, a large fire is not
necessary. A large fire not only wastes energy, it usually results in home being too warm for comfort.
The following steps will serve as a guide for operating your stove.
BUILDING A FIRE:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Open door.
While looking inside the firebox, operate damper bypass door in and out observing movement. If door does not operate
freely and seal to door opening, then door has jumped out of its track during shipping and/or installation.
Open primary air control on right side of stove. Also, open outside air control if so equipped (mobile home
installations).
Twist two pieces of non-colored newspaper into a roll and place them on floor of firebox.
NOTE: “Do not use grate or elevate fire. Build wood fire directly on inner bottom of fire box.”
The Model 20 is not designed for use of grates and irons or other methods of supporting fuel.
Lay several pieces of dry kindling on top of newspaper.
Place three or four small pieces of firewood, 2-3” in diameter, on top of kindling.
Light newspaper in front, close and latch door. Don’t leave fire unattended at this point. The draft system of heater
should start quickly. It may be necessary to preheat chimney to get draft started. To do this, open door and add
newspaper to top rear of wood. Light or let this paper ignite and allow to burn while holding door slightly cracked.
Once draft has started, close and lock door.
NOTE: After embers and a coal bed have been established, load heater with seasoned natural hard wood,
placing it length way front to rear.
NOTE: If blower is being used on the Model 20 Room Heater, it is equipped with a automatic thermostat.
When stove gets hot enough, thermostat will activate room air blower. (For operation of switch
and blower, See Page 36)
NOTE: When refueling or removing ashes turn “OFF” room air blower. Be sure to turn room air blower back on
when finished.
NOTE: Do not run power cord underneath heater or in walk way or heavy traffic areas.
NOTE: THE FUELING DOOR MUST REMAIN CLOSED DURING OPERATION.
MODEL 20 OPERATION
A. Low Burn Rate: Set primary air control to low setting. Set the Auto-Off-Manual switch to Auto position. Wood
Loading—During refueling, open (pull-out) bypass damper to allow smoke in firebox to escape, open door and
add wood. Immediately close door and bypass damper. Reopen door 1/4” for one (1) minute to charge wood.
Close and latch door. After most of wood is burned, if you are not planning on reloading immediately, it may be
necessary to open bypass damper and door to rake wood and coals into a pile near front center of firebox. (Be
certain wood chunks are pulled out of rear corners.) Close door and bypass damper. This step will assure
continued combustion and thorough burning of wood.
B. Medium—Low Burn Rate: Set primary air control to medium-low setting. Set Auto-Off-Manual switch to
Auto position. Wood Loading—During refueling, open bypass damper, open door and add wood. Immediately
close door and bypass damper. Open primary air control wide open for five minutes to charge wood. Reset
primary air control to med-low setting. After most of wood is burned, if you are not planning on reloading
immediately, it may be necessary to open bypass damper and door to rake wood and coals into a pile near front
center of firebox. (Be certain wood chunks are pulled out of rear corners.) Close door and bypass damper. This
step will assure continued combustion and thorough burning of wood.
Page 30
C. Medium—High Burn Rate: Set the primary air control wide open. Set the Auto-Off-Manual switch to
Auto position. Wood Loading—During refueling, open bypass damper, open door and add wood.
Immediately close door and bypass damper. Open primary air control wide open for five minutes to
charge wood. Reset primary air control to med-high setting. After most of wood is burned, if you are not
planning on reloading immediately, it may be necessary to open bypass damper and door to rake wood
and coals into a pile near front center of firebox. (Be certain wood chunks are pulled out of rear corners.)
Close door and bypass damper. This step will assure continued combustion
and thorough burning of wood.
D. High-Burn Rate—Set primary air control wide open. . Set the Auto-Off-Manual switch to the Auto
position. Wood Loading—During refueling, open the bypass damper, open the door, and add wood.
Immediately close door and bypass damper.
NOTE: To select primary air setting, center rod where it exits the air vent opening and align to the marked settings
on the heater.

Align where handle rod exits face of air vent
You will have to experiment with the rate until you find the particular setting for heating your home. Chimney
drafts, tightness of the house doors and windows, and atmospheric conditions all influence which setting you must
have so it may take you several firings to learn the setting necessary for your installation.
Although the catalytic heaters decrease ash residue, routine removal of excess ash is still necessary.
Page 31
OPERATING AND SAFETY HINTS:
When preparing to refuel heater, open bypass damper (taking the heater out of catalytic mode) and wait for smoke
to clear out of firebox before opening the door.
Burn only natural seasoned hard wood in your catalytic heater. You should not burn trash or garbage, artificial or
paper logs, gift wrapping, treated or painted wood, nor should you start a fire with lighter fluid or chemical starter.
These and other compositions may contain lead, zinc or other elements that can coat catalyst and reduce its
activity.
Manufacturer recommendation for peak performance and long catalyst life is to burn natural
seasoned hardwood (wood dried 6-12 month) and place wood from front to back position in the
heater.
NOTE: Soft woods such as pine, create more creosote, clogging of chimney and produce a less
efficient burn performance.

The Main Audubon Society recently charted the heat produced by a wood fire. They noted that heat
produced by a wood fire varies greatly with kind of wood burned. Beech is considered best wood for a
fire. A cord of well-seasoned Beech will produce as much heat as 169 gallons of fuel oil; Sugar Maple
and Red Oak produce as much heat as 166 gallons of fuel oil; followed by White Ash 154; American Elm
130; White Birch 124; and White Pine 94.
HELPFUL HINTS
CURING THE PAINT ON YOUR HEATER: During the first several firings, burn small fires to cure paint and
to prevent damage to finish. It is a good idea to flip toggle switch to “Manual” position during these first firings so
blower will run continuously. This will allow paint to cure at a slower rate and creates a better overall finish.
CAUTION: Never remove ashes from your heater with blower running.
TIPS ON FIRE BURNING
GREEN WOOD vs. NATURAL SEASONED HARD WOOD-Green wood has a high moisture content and
therefore requires a hotter ignition temperature. Natural seasoned hard wood-cut at least one year before use-allows
for a quicker, prolonged burn and more complete combustion.
SPLIT WOOD vs. ROUND WOOD-Split wood burns easier and more rapidly, whether it’s seasoned or green. If
used after starting a fire, it should be packed tightly to achieve a longer burn.
Round wood burns longer, but requires more effort to start. Inserting a round piece over a bed of red coals with
damper and drafts open will help it catch fire. Round wood should be used to accomplish an all-night burn.

PREVENTIVE MAINTENANCE / PARTS REPLACEMENT
Check Chimney
A. The chimney should be cleaned as necessary to remove creosote, soot, leaves, birds’ nests, etc. (Refer to Page
27, #5 Creosote Formation.)
B. A neglected chimney can eventually cause a draw restriction or can ignite and burn hot enough to cause
damage to chimney.
C. For proper inspection chimney should be cleaned.
D. A chimney cap should be installed to prevent moisture from entering chimney, to prevent sparks and burning
materials from escaping chimney and to keep birds and foreign materials from entering.
NOTE: Some areas may require an approved spark arrestor.
CLEANING THE HEATER
A. The heater should not be cleaned with any type of detergent as most all detergents have an oil base and cannot
be painted over.
B. The heater should be lightly sanded with fine sandpaper or steel wool, then repainted or touched up with high
temperature paint.
C. If the heater is located in a moist or damp location, check thoroughly for signs of condensation during times
when heater is not in use.
D. When heating season is over, heater should be cleaned out completely with a wire brush or cloth to help
eliminate ash and burned wood smell.
CARE OF GLASS DOOR: The glass door on your heater permits you to enjoy the beauty of the fire while
retaining efficiency of your heater. Although brand of glass used in heater door has well established and
recognized heat resistant and strength characteristics, it can be broken through improper care. To achieve
maximum utility and safety of your glass door, we advise that you observe following use and safety tips:
1.
2.
3.
Inspect glass regularly for cracks or breaks. If you detect a crack or break extinguish fire immediately and
return door to your dealer for glass replacement before further use.
Do not slam heater door or otherwise impact glass. When closing door, make sure that no logs or other
objects protrude to impact against glass.
Do not clean glass with materials which may scratch it (such as steel wool) or otherwise damage glass.
Scratches on the glass can develop into cracks or breaks.
The glass can be cleaned with a commercial oven cleaner, providing it does not contain abrasives. A build-up on
glass that has been there for a considerable length of time can be burned off with a propane torch.
CATALYTIC INSPECTION
Catalytic combustors should be visually inspected at least three times during heating season to determine if
physical degradation has occurred.
Preferred Inspection Method: The easiest method to determine condition of catalysts is to observe glow of
catalyst after ignition (med-low firing or hotter). You can observe the catalysts by leaning down and looking up
through the door glass.
Page 33
a.
b.
Properly functioning catalysts will be exhibiting a uniform glow from one end to other (indicating
ignition).
Physically degraded catalysts will have cold places (areas not igniting) where plugging, crumbling or
other degradation has occurred. If this occurs, monitor probe temperature will not increase at a normal
rate. For further inspection it will be necessary to go by disassembly method as follows:
Disassembly Inspection Method: For thorough catalysts inspection, removal of catalyst housing is necessary
(cold heater only).
a.
b.
c.
d.
e.
Spread a drop cloth in front of heater.
Open door and clean out any ash.
Open bypass door to give access to two rear mounting bolts.
Using 9/16” wrench or 9/16” socket, loosen four bolts and remove catalyst housing (drop down) and place
in a suitable inspection area (it may be necessary to use penetrating oil if nuts and bolts have seized).
Inspect top and bottom side of catalysts for plugging, crumbling and other physical degradation.
1. If a problem exists, refer to Troubleshooting section of manual for possible cause of problem and
solution (including replacement if necessary).
2. Reassemble if catalysts are okay being sure stainless steel heat reflector is positioned back in its
original position and bolt housing and heat reflector securely back in place.

To replace deteriorated gaskets, following steps must be taken to ensure proper installation of gaskets.
1. Obtain proper gaskets and silicone glue from your local dealer.
2. Using pliers, remove any worn and deteriorated gaskets.
3. Using a scraper, wire brush and sandpaper or steel wool, clean glue and gasket residue from door frame.
4. Measure and cut gaskets to length. Care should be taken not to stretch gaskets. What you want is a full and
loose gasket weave after attachment to framing.
5. Obtain silicone glue and run a 3/16” bead inside door frame.
6. Obtain gasket (s) and place in gasket channel areas. Use a technique which assures that gasket is applied in a
loose like manner. DO NOT STRETCH GASKETS.
7. After gasket (s) are applied to glue, use your finger and go over all gasket gently pressing gasket to the
channel. Use same pressure against gasket so that final result is an evenly applied gasket.
8. Leave door open and allow at least one hour for glue to dry.
9. Once gaskets are checked, heater is ready for use.
10. This should be done annually. Allowing gaskets to deteriorate can cause over-firing and shorten burn time.

DEFINITIONS
AIRTIGHT HEATER—In an airtight heater, all air enters in through inlets. Generally, non-airtight stoves are not
as efficient and their level of heat output is less controllable than that of an airtight.
BURN CYCLE—Time span between refuelings in which wood is reduced to a bed of hot coals.
BYPASS—Movable door inside a woodstove that is opened when stove door is opened to give a path of least
resistance to smoke to prevent roll-out.
CREOSOTE—Condensed wood-gas vapor.
DOWNSTREAM TEMPERATURE—Outlet temperature of combustor or temperature of gas leaving
combustor from chimney side or face.
DRAFT—Amount of vacuum created by buoyant hot air in chimney. Draft pulls in oxygen for combustion
process and pulls out exhaust gases.
FIREBRICK— Brick capable of withstanding high temperatures. Used in furnaces, kilns and stoves. Used to
mean only “hard” or “dense” firebrick as distinguished from “soft” or “insulating” firebrick.
FIRING RATE—Rate at which fuel is burned in a heater.
FLAME IMPINGEMENT– Flames directly contacting combustor face.
FLUE COLLAR—The part of a stove to which chimney connector or chimney attaches.
GLOW-PLUG EFFECT—When a combustor is at temperatures above 1400o F (760o C) and periodically causes
pockets of wood gas in firebox to ignite spontaneously.
GREEN WOOD—Non-dried, freshly cut wood from a live tree.
IGNITION TEMPERATURE—The minimum temperature of a flammable mixture of gases at which it can
spontaneously ignite.
LIGHT-OFF—Activation temperature of combustor catalyst.
NOBLE-METAL CATALYST—A catalyst is a substance that can accelerate a chemical process without being
consumed by it. A noble-metal catalyst is one made of a precious metal or metals. (In the combustor, platinum and
palladium are used because they are stable under high heat conditions.)
Page 38
POSSIBLE PROBLEMS
Problems encountered with operation of catalytic-combustor equipped wood heaters are usually the same as those
experienced in operation of traditional wood heaters. Our experience has shown that adoption of good operating
practices will eliminate most of these problems. In addition, it should be noted that problems with catalytic
combustors are rare. Fewer than 1 percent of combustors are returned for any reason. Nonetheless, installers and
retailers should make themselves aware of nature, cause and solution to possible problems so as to serve their
customers better.
Plugging-Plugging can occur if combustor is operated improperly. It may occur if wrong materials are burned.
Evidence of these types of plugging is a coating of black soot, creosote or fly ash on combustor. Burning materials
that produce large flakes of char, such as Christmas wrapping paper or cardboard, can plug enough cells to cause
smoke spillage.
Extreme Temperature-A combustor becomes extremely hot during operation. Temperatures between 1400o F and
1600o F (760o C - 870o C) are common, but operating temperatures between 1200o F and 1400o F (650o C - 760o C)
are recommended. Most of this heat is transmitted to surrounding heater parts via thermal radiation.
Flow Restrictions-Because combustor is mounted in gas flow stream, it does offer resistance to draft. This
restriction or resistance presents two problems:
If the bypass is not open when fuel-loading door is opened, smoke rollout will occur.
Chimneys that produce marginal draft may prevent operation of a combustor-equipped device. A chimney
that provides, on average, .02” of water draft in low-fire operation would probably not operate with a catalytic
combustor appliance in low-fire mode. In such a case, combustor resistance would offset remaining draft,
resulting in a system that will not draft.
Creosote Build-up-Even though reduction of creosote is one of primary advantages of a combustor-equipped
device, some creosote-forming gases will escape unburned during normal operation. In event combustor ceases to
function, creosote can be expected to accumulate. Consequently, flues and chimneys should be inspected regularly
(every 2-3 months of operation) and any creosote build-up removed. Failure to do this could result in a chimney
fire.
Chemical Deactivation-Deactivation can occur when catalyst is attacked by materials such as compounds of
sulphur, phosphorus or lead and other heavy metals. Burning large quantities of trash, pressure-treated lumber or
painted wood can deactivate catalyst. The operator takes a chance when burning anything other than natural wood.
The catalysts are durable and are not likely to be greatly affected by an occasional mistake, but burning large
quantities of chemical-laden materials will appreciably shorten life of combustor. The catalyst can also be
deactivated when it is coated with excessive creosote, carbon or fly ash. This build-up greatly reduces the amount
of catalyst available to react with the smoke.
Excessive Handling-An older combustor, especially one that is “uncanned”, is susceptible to handling damage.
Stress-relief cracks may develop in service but will not affect performance of combustor if it is not moved or
handled. Handling a unit with these cracks, however, could result in it breaking apart. Excessive handling could
also potentially remove some of catalyst coating.
Condensation In Chimney-The burning that takes place in a combustor converts harmful hydrocarbons and
carbon monoxide to heat, carbon dioxide and water. The additional water produced by this complete burning can
lead to associated problems in the chimney.
Page 39
Backpuffing-A hot combustor (above 1400o F) can sometimes act like a glow plug (spontaneous combustion
ignitor). Usually wood gas-to-air mixture is either too lean or too rich to form a highly flammable mixture. There
are times when this mixture is just right within firebox during normal burning process. If combustor is running at
or above ignition temperature of mixture, spontaneous combustion will result, causing stove to vent puffs of
smoke.
Non-Uniform Flow-Non-uniform flow causes combustor to heat and cool unevenly and is a result of fuel-loading
configuration. This occurs when flow pattern of fire is concentrated on one side of combustor. This condition
causes thermal stress within ceramic, resulting in cracking.
TROUBLESHOOTING
Operation of any wood heater can create problems. While nuse of a catalytic-combustor equipped stove will
substantially lessen some of these problems—such as creosote formation—other traditional wood-heater problems
may remain.
The following guidelines apply to operation of all wood heaters, with problems related to catalytic heaters
addressed where appropriate.

The Zero-Clearance cabinet and the Model 20 (hereafter referred to as the ZC20) is designed for installation in a
family dwelling, where minimum clearance is desired.
INSTALLATION PRECAUTIONS
The following precautions are mandatory for a safe installation:
A. Compliance with local building codes and regulations is mandatory.
B. Be careful not to damage unit in handling and unpacking component parts and accessories.
C. A UL Listed and Approved Chimney System is to be used and vented to outside of the building. See chimney
list above.
D. The chimney must extend a minimum of 3’ above the highest point where it penetrates the roof (3’ above a
flat roof or up to 2 1/2 pitch roof), and chimney must extend a minimum of 2’ higher than any portion of
building within 10’ of chimney. The minimum height is 12’. A 2” clearance must be maintained between
chimney and any combustible materials at all points.
E. A rain cap must be used to terminate chimney to prevent down-draft.

F.
DO NOT build a fire directly inside the ZC Cabinet. It is designed solely for housing Model 20 Stove.
G. WARNING: This fireplace has not been tested for use with a chase above roof.
H. Do not connect this unit to a chimney serving another appliance.
SELECTING A CHIMNEY INSTALLATION AND LOCATION
There are two basic types of chimney installations possible with the ZC20; straight up through a ceiling and chase
installation, either outside or inside. These are normally used as follows:

OFFSET TO CLEAR OBSTRUCTION
Page 49
NOTE: Chase Installation: (See Figure 3). A chase is an enclosure built specifically to house a chimney. The
interior of a chase is open from ZC20 to roof, eliminating need to cut through ceilings and roof. Normally, a chase
is built outside and against exterior wall of a home. A hole is cut through wall and the ZC20 is located in bottom of
chase, with front of unit flush with interior wall. Chases are commonly veneered on outside with brick, stone or
wood to give appearance of a conventional fireplace flue. Occasionally, they are built inside and boxed in, similar
to a stairwell. When making a chase installation, it is important to read chimney manufacturer’s instructions prior
to building, as there are specific requirements for bracing a free-standing flue and must be planned for. There are
also occasions where offsets are used within a chase to accommodate unusual building designs or to locate ZC20
further into a room.
FRAMING CONSTRUCTION AND INSTALLATION
Except as noted, ZC20 can be installed almost anywhere you desire. There are, however, a few clearance and
framing restrictions that must be followed. See Figure 3 and 4 to make sure that these clearance restrictions are
met. It is much wiser to place your ZC20 correctly at start of installation than to be forced to relocate it after much
of work is done.
You must ensure that floor is of adequate strength to accept load of this unit. If inadequate, floor will require
additional support, such as bracing. NOTE: A wooden base constructed of plywood or 2”x4” boards is required in
order to get proper clearance above the extended hearth (millboard, rock, stone, etc.).
Good planning is essential for a satisfactory installation, therefore, at this point you should have decided where
ZC20 is to be located and the route chimney will follow to the roof—straight up or chase. If you cannot decide
best route, contact your Dealer for assistance with planning.

Position ZC20 for installation as follows:
1. Thoroughly clean area where unit will be placed. Remove any carpeting/padding from area where the ZC20
will be installed.
2. Lay out location on the floor for ZC cabinet. (See Figure 4)
3. Lay out for hearth extension preparation and removal of carpet and padding.
4. A sheet metal safety shield is placed 1 1/2” under cabinet. It must extend out under floor protector.
5. Now, you are ready to install chimney system for ZC20. If you are building an outside chase, follow approved
Chimney Manufacturer’s instructions. If you are penetrating a ceiling, install the chimney as follows:
a. Drop a plumb line, locate, and mark point on ceiling directly over center of ZC20 chimney adapter
b. After locating center of hole, install fire stop spacer per chimney manufacturer’s instructions.
Page 50
6.
Obtain listed and approved chimney installation instructions and follow exactly.
a) Obtain starter section of pipe and install on ZC20 cabinet. It may be necessary to crimp the inside of
starter pipe to ease installation into the ZC20 cabinet.
b) Obtain the two short sheet metal “ell” brackets and sheet metal screws provided with ZC20 and secure
starter section of pipe to the ZC20 cabinet.
Install pipe to cabinet by pushing
down over starter section of pipe on
the ZC cabinet.

CAUTION: Maintain a 3/4” air
space between back and 1 1/2”
between the side walls and
combustible material.
Figure 5
c) Continue adding lengths of chimney until you are ready to penetrate another ceiling or roof.
d) Now, plumb bob center of ceiling or roof above chimney and install another firestop for another ceiling
penetration or follow pipe manufacturer’s instructions for attic and roof penetration.
e) Once roof penetration is made, install flashing.
f) Add applicable lengths of chimney, extending through roof until following conditions are met:
1. Chimney height is at least 12’ to 15’ maximum.
2. The chimney must extend a minimum of 3’ above highest point where it penetrates roof.
3. The chimney must extend a minimum of 2’ higher than any portion of building within 10’ of the
chimney.
g) Install the chimney cap and storm collar.

The ZC20 cabinet is now ready for framing as follows:
a) Frame the ZC20 using 2”x4” studs or local building code framing. Some minor framing restrictions are
required:
1. Adjacent side walls must be at least 16” from outer edge of ZC20 trim panel
2. The overall opening dimensions must be at least 37 15/16” wide and 34 5/8” high.
NOTE: Maintain 1 1/2” clearance at side walls of cabinet and combustible material.
b) 2”x4” framing above the unit must be turned flat. This allows proper clearance from framing to chimney
(2” minimum). (See Figure 6).

Next construct hearth extension out of non-combustible inorganic building materials as follows:
a) The hearth extension must extend 17” in front of rough framed opening on ZC20.
b) The hearth extension width must be at least 37 15/16”.
c) The hearth extension must be made of brick 2” thick, a listed “Hearth Extension” or “Floor Protector” or a
hearth extension made of non-combustible inorganic material with a K* factor of:
K = 2.5 BTU ((HR) (ft2) (oF/in.))
ALTERNATE FLOOR PROTECTORS MATERIALS
With floor protector or hearth extension material specified as one layer of 2” thick brick with a K* factor of 5.0,
you may use alternate materials as long as the K* factor (s) is calculated as follows:
Formula: Required thickness = (K of alternate material/K of millboard) X (thickness of millboard)
Example: An alternate inorganic non-combustible millboard with a K of .9375 would require a thickness
as follows:
Required thickness = .9375.0o x 2 inch
= 3/8 inch

and putting any type decorative brick or stone (any thickness) on top of it.
*The K* factor represents thermal conductivity of a material and is time rate of heat flow through a homogeneous
material under steady-state conditions, through unit area, per unit temperature gradient in the direction
perpendicular to a surface.

Page 59
CLEANING THE UNIT
A. The unit should be lightly sanded with fine sandpaper or steel wool, then repainted or touched up with high
temperature black paint.
B. If unit is located in a moist or damp location, check thoroughly for signs of condensation during times when
unit is not in use.
C. When heating season is over, unit can be cleaned out completely with a wire brush or cloth to help eliminate
ash and burned wood smell.
SAFETY PRECAUTIONS
1.
Use smoke detectors around stove as well as in sleeping areas.
2.
Keep a fire extinguisher rated for Class “A” fires near stove.
3.
Check with your insurance company to be sure your policy covers installation and use of a wood burning
appliance.
4.
Creosote-Formation and Need for Removal: When wood is burned slowly, it produces tar and other organic
vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in relatively
cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on flue lining. When
ignited this creosote makes an extremely hot fire.
The connector and/or chimney should be inspected at least once every two months during heating season
to determine if a creosote buildup has occurred.
If creosote has accumulated, it should be removed to reduce risk of a chimney fire.
5.
Locate furniture and any other combustibles away from stove.
6.
Store firewood at a safe distance from stove.
7.
Disposal of Ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed container of
ashes should be placed on a non-combustible floor or on ground well away from all combustible materials,
pending final disposal. If ashes are disposed of by burial in soil or otherwise locally dispersed, they should be
retained in closed container until all cinders have thoroughly cooled.
8.
Always exercise caution when using your fireplace. Be particularly careful when there are children around an
operating fireplace.
CAUTION: NEVER use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid or similar liquids to
start or “freshen-up” a fire in fireplace. Keep all such liquids well away from stove when it is in use. All fluids of
this type give off highly volatile fumes and can and WILL EXPLODE! Don’t take a chance with safety of your
home and family.
Page 60
PREVENTIVE MAINTENANCE/
SAFETY PRECAUTIONS
CHIMNEY
A. The chimney should be cleaned as necessary to remove creosote, soot, leaves, birds’ nests, etc.
CREOSOTE-FORMATION AND NEED FOR REMOVAL
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to
form creosote. The creosote vapors condense in relatively cool chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on flue lining. When ignited this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected at least once every two months. More frequent inspection
and cleaning may be necessary. Under certain conditions of use creosote build-up may occur rapidly.
Creosote is caused by low temperatures in chimney, which is controlled by operator of stove.
B. A neglected chimney can eventually cause a draw restriction or can ignite and burn hot enough to cause
damage to chimney.
C. For proper inspection chimney should be cleaned.
CHIMNEY CLEANING:
1.
Access-Chimneys must be installed so that access is provided for inspection and cleaning.
2.
When to Clean-The chimney should be inspected at least once every two months during heating season to
determine if creosote or soot has built up. Check spark arrestor screens every 2-4 weeks. If creosote or soot
has accumulated, it should be removed to reduce risk of chimney fire.
3.
How to Clean-Have your chimney cleaned by a professional chimney sweep if you have doubts about your
ability to clean it, using a plastic, wood, or steel brush. Do not use a brush that will scratch the stainless steel
liner of your chimney. Scrub spark arrestor with a wire brush.
To remove chimney cap for cleaning, unscrew four screws that attach the cap’s support legs to cap
base. The top cleanout cap can be removed once screws are unscrewed. Remember to replace screws
when you are through cleaning chimney.
4.
No Chemical Cleaners-Do not use chemical chimney cleaners. Their use does not eliminate need for
mechanical cleaning and they may be highly corrosive.
5.
In Case of Fire-If a flue fire occurs, close all appliance draft openings and call your Fire Department. Do not
use chimney again until it is inspected for possible damage.
6.
Chimney Protection-Painting. To increase chimney life, coat all exterior metal parts with high temperature
rust-proof paint. This is highly recommended, particularly in areas near the ocean. Wash the metal with a
vinegar and water solution before painting.
