Encore Woodburning Stove
Installation
Before you begin an installation, be sure that:
• Your stove and chimney connector will be far
enough from combustible materials to meet all
clearance requirements.
• The floor protector is large enough and is constructed properly to meet all requirements.
• You have all necessary permits from local authorities.
Your local building official is the final authority for approving your installation as safe and determining that it
meets local and state codes.
The metal label permanently attached to the back of
every Vermont Castings’ stove indicates the stove has
been tested to current UL and ULC standards, and
gives the name of the testing laboratory. Clearance
and installation information also is printed on the label.
When the stove is installed according to the information
both on the label and in this manual, local authorities
in most cases will accept the label as evidence that the
installation meets codes and can be approved.
However, codes vary in different areas. Before starting
the installation, review your plans with the local building
authority. Your local dealer can provide any additional
information needed.
For any unresolved installation issues, refer to the
National Fire Protection Association’s publication
ANSI/NFPA 211 Standard for Chimneys, Fireplaces,
Vents and Solid Fuel Burning Appliances. For Canada,
the equivalent publication is CSA CAN-B365 Installation
Code for Solid Fuel Burning Appliances and Equipment.
These standards are the basis for many national codes.
They are nationally recognized and are accepted by
most local authorities. Your local dealer or your local
building official may have a copy of these regulations.
IMPORTANT: FAILURE TO FOLLOW THESE INSTALLATION INSTRUCTIONS MAY RESULT IN A
DANGEROUS SITUATION, INCLUDING A CHIMNEY
OR HOUSE FIRE. FOLLOW ALL INSTRUCTIONS
EXACTLY, AND DO NOT ALLOW MAKESHIFT COMPROMISES TO ENDANGER PROPERTY AND PERSONAL SAFETY.

Outside Air
In some modern, super-insulated homes, there is
inadequate air for combustion because of insufficient
air infiltration into the building. Such air enters a home
through unsealed cracks and openings. Exhaust fans
for kitchen or bath can compete with the stove for available air and compound the problem.
When poor draft is caused by a low infiltration rate,
opening a ground floor window on the windward side
of the house and in the vicinity of the stove will usually
alleviate the problem.
Another solution is to install a permanent outside air
supply to the stove and/or room. In fact, bringing air
for combustion from outside the home directly to the
air inlet of the stove is required for new construction in
some areas.
Pressure variations within the house do not affect a
stove equipped with an outside air supply, and improved stove performance often results. An Outside Air
Adapter Kit for the Encore is available from your local
Vermont Castings dealer.
Chimney Height
Altitude affects chimney performance. When using a
6” flue collar on the Encore, refer to Figure 2 for suggested chimney heights at various altitudes. Chimney
height should be measured from the flue collar to the
top of the chimney. The recommended minimum chimney height is 16’ (4.9m).

Masonry Chimneys
What Kind of Chimney to Use
You must connect the Encore to a code-approved
masonry chimney with a flue liner, to a relined masonry
chimney that meets local codes, or to a prefabricated
metal chimney that complies with the requirements
for Type HT chimneys in the Standard for Chimneys,
Factory-Built, Residential Type and Building Heating
Appliance, UL 103. (Fig. 3) The chimney and chimney
connector must be in good condition and kept clean.
A prefabricated doublewall insulated chimney
An inspection of the chimney must confirm that it has
a lining. Do not use an unlined chimney. The chimney
should have no cracks, loose mortar, other signs of
deterioration, and blockage. Repair any defects before
the chimney is used with your stove.
Unused openings in an existing masonry chimney must
be sealed with masonry to the thickness of the chimney
wall, and the chimney liner should be repaired. Openings sealed with pie plates or wallpaper are a hazard
and should be sealed with mortar or refractory cement.
In the event of a chimney fire, flames and smoke may
be forced out of these unused thimbles.
The chimney should be thoroughly cleaned before use.
A newly-built masonry chimney must conform to the
standards of your local building code or, in the absence
of a local code, to a recognized national code. Masonry
chimneys must be lined, either with code-approved
masonry or pre-cast refractory tiles, stainless steel
pipe, or a code-approved, “poured-in-place” liner. The
chimney’s clean-out door must seal tightly.

The chimney should extend at least 3’ (914 mm) above
the highest point where it passes through a roof, and at
least 2’ (610 mm) higher than any portion of a building
within 10’ (3 m). (Fig. 4)
For proper draft and good performance, any chimney
used with an Encore should extend at least 16’ (5 m)
above the flue collar of the stove.

Chimney Size
An Encore with an 8” (203 mm) flue collar is approved
for venting into a masonry chimney with a nominal flue
size of 8” x 8” (203 x 203 mm) or 8” x 12” (203 x
305 mm), and into a round flue with nominal flue size of
8” (203 mm). An Encore with a 6” (152 mm) flue collar
is approved for venting into a masonry chimney with a
nominal flue size of 8” x 8” (203 x 203 mm), and into a
round flue with nominal flue of 6” (152 mm).
NOTE: When installed with a 6” flue collar, the
Encore may not be operated with the front doors
open.
0 To 10'
Reference
Point
A prefabricated metal chimney must be one tested and
listed for use with solid-fuel burning appliances to the
High-Temperature (H.T.) Chimney Standard UL-1031985 (2100°F) for the United States, and High Temperature (650°C) Standard ULC S-629 for Canada.
Whatever the flue collar size, an Encore may be vented
into larger chimneys as well. However, chimneys with
liners larger than 8” x 12” (203 x 305mm) may experience rapid cooling of smoke and reduction in draft, especially if the chimneys are located outside the home.
These large chimneys may need to be insulated or
have their flues relined for proper stove performance.
Accessories to help make the connection between
stainless steel chimney liners and your Encore are
available through your local dealer.

Encore Woodburning Stove
Chimney Connector Guidelines
Single-wall Chimney Connectors
A chimney connector is the double-wall or single-wall
pipe that connects the stove to the chimney. The chimney itself is the masonry or prefabricated structure that
encloses the flue. Chimney connectors are used only to
connect the stove to the chimney, as in Figure 5.
• Begin assembly at the flue collar of the stove. Insert
Double-wall connectors must be tested and listed for
use with solid-fuel burning appliances. Single-wall connectors should be made of 24 gauge or heavier steel.
Do not use galvanized connector; it cannot withstand
the high temperatures that can be reached by smoke
and exhaust gases, and may release toxic fumes under
high heat. The connector may be 6” (152 mm) or 8 “
(203 mm) in diameter.
If possible, do not pass the chimney connector through
a combustible wall or ceiling. If passage through a combustible wall is unavoidable, refer to the section on Wall
Pass-Throughs. Do not pass the connector through an
attic, a closet or similar concealed space. The whole
connector should be exposed and accessible for inspection and cleaning.
In horizontal runs of chimney connector, maintain a distance of 24” (610 mm) from the ceiling. Keep it as short
and direct as possible, with no more than two 90° turns.
Slope horizontal runs of connector upward 1/4” per foot
(6 mm per meter) going from the stove toward the chimney. The recommended maximum length of a horizontal
run is 3’ (1 m), and the total length should be no longer
than 8’ (2.4 m). In cathedral ceiling installations, extend
the prefabricated chimney downward to within 8’ (2.4 m)
of the stove.
Wear gloves and protective eyewear when drilling,
cutting or joining sections of chimney connector.
Double-wall Chimney Connectors
Information on assembling and installing double-wall
connectors is provided by the manufacturer of the
double-wall pipe. Follow the manufacturer’s instructions
exactly as you assemble the connector and attach it to
the stove and chimney. Using chimneys and connectors
from the same manufacturer makes the assembly and
installation straightforward.
NOTE: For installations using double-wall connectors,
minimum clearances must conform to the listed clearances in the clearance chart on Page 14.
If the Encore is equipped with the 8” flue collar, an ovalto-round adapter will be needed. Double-wall oval-toround adapters are available from some manufacturers.
Your local dealer can help you select the right connector.

installations follow.
12/13/99 djt
Be sure the installed stove
and chimney connector are correct distances from
nearby combustible materials.
NOTE: Special slip pipes and thimble sleeves that form
telescoping joints between sections of chimney connector are available to simplify installations. They often
eliminate the need to cut individual connector sections.
Consult your local dealer about these special pieces.
Securing the Single-wall Connector to a
Prefabricated Chimney
Follow the installation instructions of the chimney
manufacturer exactly as you install the chimney. The
manufacturer of the chimney will supply the accessories to support the chimney, either from the roof of
the house, at the ceiling of the room where the stove is
installed, or from an exterior wall.
Special adapters are available from your local dealer
to make the connection between the prefabricated
chimney and the chimney connector. The top of such
adapters attaches directly to the chimney or to the
chimney’s ceiling support package, while the bottom of
the adapter is screwed to the chimney connector.
These adapters are designed so the top end will fit
outside the inner wall of the chimney, and the bottom
end will fit inside the first section of chimney connector.
When assembled in this way, any soot or creosote falling from the inner walls of the chimney will stay inside
the chimney connector.

Freestanding Installations
If the chimney connector must pass through a combustible wall to reach the chimney, follow the recommendations in the Wall Pass-Through section that follows.
The opening through the chimney wall to the flue
(the “breech”) must be lined with either a ceramic or
metal cylinder, called the “thimble”, which is cemented
securely in place. Most chimney breeches incorporate
thimbles, but the fit must be snug and the joint between
the thimble and the chimney wall must be cemented
firmly.
A special piece called the “thimble sleeve,” slightly
smaller in diameter than standard connectors and
most thimbles, will facilitate the removal of the chimney
connector system for inspection and cleaning. Thimble
sleeves should be available from your local dealer.
To install a thimble sleeve, slide it into the breech until
it is flush with the inner flue wall. Do not extend it into
the actual flue passage, as this could interfere with the
draft.
2000956
The thimble sleeve should protrude 1-2” (25-50mm) into
the room. (Fig. 7) Use furnace cement and thin gasketing to seal the sleeve in place in the thimble. Secure

screws. djt
Without a thimble, a suitable length of chimney connector can be extended through the breech to the inner
face of the flue liner, and cemented securely in place.
Additional pieces of connector are then attached with
sheet metal screws.
Fireplace Installations
The chimney connector may be connected to the
chimney above the fireplace opening or through the
fireplace.
Above the Fireplace
The Encore may be connected to a chimney above
a fireplace opening. (Fig. 8) In such installations, the
stove is positioned on the hearth in front of the fireplace
and the chimney connector rises from the stove top and
then angles ninety degrees back into the chimney. The
chimney liner should extend to the point at which the
chimney connector enters the chimney.
If the chimney connector from your installation enters
the chimney above a fireplace, follow all the guidelines
mentioned above for freestanding installations. In addition, give special consideration to the following points:
• Check the clearance between the stove and the
chimney connector, and any combustible trim or the
mantel. Use the necessary combination of mantel, trim,
and connector heat shields to achieve the required
clearances.
• Check the clearance between the chimney connector and the ceiling. If no heat shields are used, the
clearance should be at least 24” (610 mm). To find out
how much this clearance may be reduced with heat
shields, refer to the clearance chart on Page 14.

is at least 26¹⁄₂" (675 mm),
12/99
you may install an Encore through the opening using a
“positive connection” kit, available from your local dealer.
These positive connection kits ensure a tight fit between
the stove flue collar and the chimney flue. (Fig. 9)
Fireplace installations, whether connected to the flue
above or through the fireplace opening, have special
clearance requirements to adjacent trim and the mantel.
You’ll find the required safe clearances for Encore fireplace installations on Page 12.
Floor protection requirements also apply to fireplace
installations. This information is on Page 10.
Wall Pass-Throughs
Whenever possible, design your installation so the connector does not pass through a combustible wall. If you
are considering a wall pass-through in your installation,
check with your building inspector before you begin.
Also, check with the chimney connector manufacturer
for any specific requirements.
Accessories are available for use as wall passthroughs. If using one of these, make sure it has been
tested and listed for use as a wall pass-through.

Fig. 9 In this installation, the chimney connector enters the
firepalce opening and then connects to the chimney.
In the United States, ST245
the National Fire Protection Asfireplace
sociation (NFPA) has established
guidelines for passing
flex connector
chimney connectors through
combustible
walls. Many
12/99
building code inspectors follow these guidelines when
approving installations.
Figure 10 shows one NFPA-recommended method.
All combustible material in the wall is cut away from
the single-wall connector to provide the required 12”
(305mm) clearance. Any material used to close up the
opening must be noncombustible.
Three other methods are also approved by the NFPA:
• Using a section of double-wall chimney with a 9”
(229 mm) clearance to combustibles.
• Placing a section of chimney connector inside
a ventilated thimble, which in turn is separated from
combustibles by 6” (152 mm) of fiberglass insulating
material.
• Placing a section of chimney connector inside a
section of 9” (230 mm) diameter, solid-insulated, factory-built chimney, with 2” (51 mm) of air space between
the chimney section and combustibles.
In Canada, The Canadian Standards Association has
established different guidelines. Figure 10 shows one
method, in which all combustible material in the wall is
cut away to provide the required 18” (457 mm) clearance for the connector. The resulting space must remain empty. A flush-mounted sheet metal cover may be
used on one side only. If covers must be used on both
sides, each cover must be mounted on noncombustible
spacers at least 1” (25 mm) clear of the wall.

Heat protection is provided through the use of a Vermont Castings Bottom Heat Shield #0164. Spark and
ember protection must be provided by a floor protector
constructed with noncombustible material as specified.
Most installations will require the bottom heat shield be
attached. Only when the stove is placed on a completely noncombustible surface such as unpainted concrete
over earth may it be used without the heat shield.
Even when the bottom heat shield is installed, you must
provide special protection to the floor beneath. For
installations with the heat shield attached, use a noncombustible floor protector such as 1/4” nonasbestos
mineral board or equivalent, or 24 gauge sheet metal.
The floor protector may be covered with a noncombustible decorative material if desired. Do not obstruct the
space under the heater.
Protection requirements vary somewhat between the
Untied States and Canada as follows:
U. S. installations the floor protector is required under
the stove and must extend at least 16” (not including
the ash lip) from the front of the stove (“F”, Fig. 12), and
at least 6” from the sides and rear. (“D” and “E”, Fig.
12) It must also extend under the chimney connector
and 2” to either side. (“C”, Fig. 12) For the 8” (203 mm)
connector, the protector must be a minimum of 12”
(305 mm) wide. For the 6” (152 mm) connector, the
protector must be 10” (254 mm) wide. The protector
must be centered under the connector.
To meet these requirements, a floor protector must be
at least 39” wide and 44” deep.
T
In Canada: A noncombustible floor protector is required
under the stove as well. The floor protector must
extend 18” (457 mm) to the front (“F”, Fig. 12), and 8”
(203 mm) from the sides and rear. (“D” and “E”, Fig. 12)

Floor Protection for Fireplace Installations
Do not assume that your fireplace hearth is completely
noncombustible.
Many fireplace hearths do not meet the “completely
noncombustible” requirement because the brick or
concrete in front of the fireplace opening is supported
by heavy wood framing. (Fig. 13) Because heat passes
through brick or concrete readily, it can easily pass
through to the wood. As a result, such fireplace hearths
can be a fire hazard and are considered a combustible
floor.
Keep in mind, also, that many raised hearths will extend
less than the required clearance from the front of the
heater when it is installed. In such cases, sufficient
floor protection as described above must be added in
front of the hearth to satisfy the minimum floor protector
requirement from the front of the stove: 16” (406mm)
from the front in the United States and 18” (459mm)
from the front in Canada.
Hearth rugs do not satisfy the requirements for floor
protection.
Fireplace installations also have special clearance
requirements to the side walls, side decorative trim, and
fireplace mantel. This information follows in the section
on Fireplace and Mantel Trim Shields.

installationdjt
requires
that adequate clearance be maintained between the
hot stove and its connector and nearby combustibles.
Clearance is the distance between either your stove
(measured from the bottom edge of the stove’s top
plate) or chimney connector, and nearby walls, floors,
the ceiling, and any other fixed combustible surface.
Your stove has special clearance requirements that
have been established after careful research and testing to UL and ULC standards. These clearance requirements must be strictly observed.
In addition, furnishings and other combustible materials must be kept away from the stove as well. In general, a distance of 48” (1219mm) must be maintained
between the stove and moveable combustible items
such as drying clothes, furniture, newspapers, firewood,
etc. Keeping those clearance areas empty assures that
nearby surfaces and objects will not overheat.
Reducing Clearances Safely with Shields
Clearance requirements are established to meet every
installation possibility, and they involve the combination
of four basic variables:

When the wall has a heat shield mounted on it.
2000956
Encore Woodburning Stove
In general, the greatest clearance is required when you
place a stove and its connector with no heat shields
near a wall with no heat shield.
For example, when the Encore is installed parallel to
the rear wall and no shields are used, it must be at least
31” (787 mm) from the wall behind it and at least 24”
(610 mm) from walls on either side.
If the Encore is installed in a corner and no shields
are used, the corners of the stove must be at least 24”
(610 mm) from nearby walls.
The least clearance is required when both the stove
and its connector, as well as the wall, have heat
shields.
When shields are attached to the stove or chimney
connector, they are mounted 1” - 2” (25-51 mm) away
from the stove or connector surface on noncombustible
spacers. Air flowing between the stove (and/or chimney
connector) and nearby shields carries away heat. Do
not block the air flow by filling this empty space with any
insulating material.
The shiny shield surface facing the heat source must be
left unpainted, enabling it to reflect heat back towards
the stove or connector and away from the wall.
Clearances may be reduced only by means approved
by the regulatory authority, and in accordance with the
clearances listed in this manual.
Because of their restricted air flow and heat retention
characteristics, specific construction requirements and
special clearances apply to installations into alcoves.
Refer to the diagrams on Page 10, and contact your
Vermont Castings Dealer for details before beginning
an alcove installation.
NOTE: ALCOVE INSTALLATION OF THE ENCORE
IS NOT PERMITTED IN CANADA.
Stove Heat Shields
The Vermont Castings Encore Rear Heat Shield is one
way to reduce the clearance to the rear wall. The rear
heat shield can be installed on either rear- or top-venting stoves. However, since the chimney connector
also radiates heat toward the wall in top-venting installations, you should use a chimney connector shield
whenever you use the rear heat shield on top-venting
stoves.
Clearance reductions with the rear heat shield apply
only to the wall to the rear in parallel installations. Neither the side clearance requirement nor the clearance
requirement in corner installations may be reduced.
2000956
Wall Shields
One way to reduce clearances is with a wall shield
constructed of 24 gauge or heavier sheet metal, or of
another noncombustible material such as 1/2” (13 mm)
insulation board or common brick “laid on flat,” with the
3¹⁄₂" (90 mm) side down.
Shields must be spaced out from the combustible
surface 1" (25 mm) on noncombustible spacers, as in
Figure 13. The spacers should not be directly behind
the stove or chimney connector.
Air must be able to flow between the wall and the
shield. At least 50% of the bottom 1" (25 mm) of the
shield should be open and the shield must be open at
the top. Use metal screening, as in Figure 14, to keep
stray objects from falling behind the shield.
The shield for a top-exit stove must extend 10" (254 mm)
above the top of the stove; for a rear exit configuration, the shield must be 36” (914 mm) high. The shield
for the chimney connector must be 30” (762 mm) wide,
centered behind the pipe; for installations that use an
approved prefabricated chimney to pass through the ceiling, the chimney connector shield must stop 1” (25 mm)
below the ceiling.

Encore Woodburning Stove
Chimney Connector Heat Shields
Chimney Connector Heat Shields should be used
whenever the rear heat shield is used, or in any other
situation when it is necessary to protect nearby combustibles from the heat of the connector. The ceiling
above horizontal runs of chimney connector must be
protected as well if the clearance is inadequate.
In top-exiting installations, the connector shield must
extend to a point exactly 28” (710 mm) above the flue
collar or to an elbow in the connector, whichever is less.
If the top-exiting connector extends to the ceiling where
it connects with a prefabricated insulated metal chimney, an additional ceiling heat shield must be installed
that is 24” (610 mm) in diameter and that extends 1”
(25 mm) below the ceiling. The ceiling shield must be
constructed of 24 gauge or heavier sheet metal, and
must be centered on the chimney.

A fireplace installation requires special clearance between the side of the stove and the right and left walls,
between the side of the stove and the decorative side
trim on the fireplace face, and between the top of the
stove and the mantel.
Noncombustible shields installed 1” (25 mm) from the
combustible surface on noncombustible spacers, called
ventilated shields, may be used to reduce clearances.
To protect a mantel from the heat of an Encore in a
fireplace installation, use a custom-made ventilated
mantel shield that is at least 48” (1219 mm) long, that is
centered over the stove. (Fig. 15) Ventilated shields for
side trim must extend the full length of the trim.
An unprotected mantel (“A”, Fig. 16) cannot be more
than 9” (229 mm) deep and must have a minimum
clearance of 39” (990 mm), measured from the stove’s
top plate. With a ventilated shield, this clearance may
be reduced safely to 18” (457 mm).
Unprotected top trim (B) protruding 9” (229 mm) or less
from the face of the fireplace must be a minimum of 39”
(990 mm) from the stove’s top surface. With a ventilated trim shield, this clearance may be reduced safely
to 18” (457 mm).

Andirons Help Protect the Glass
A Surface Thermometer is a
Valuable Guide to Operation
An optional surface thermometer lets you know when
to adjust the air control, when to refuel, and when your
catalyst is operating properly.
For example, when the thermometer registers at least
450°F (230°C) after start-up you know the stove is hot
enough to begin catalytic combustion and it may be
time to close the damper. Note that the stove will warm
up much sooner than the chimney, though; a warm
chimney is the key to easy, effective stove operation.
Please review the draft management information on
Pages 25-27 to see how the size, type, and location
of your chimney will affect your stove operation. When
thermometer readings drop below 350°F (175°C) it’s
time to adjust the air control for a higher burn rate or
to reload the stove. A temperature reading over 750°F
(385°C) is a sign to cut back on the air supply to slow
the burn rate.
Your stove has andirons to keep logs away from the
glass panels. The andirons are essential to maintain
clear fireviewing, and should be left permanently in
place. Since the andirons may slightly hinder refueling
through the front doors, most stove owners will prefer
the convenience of top loading through the griddle.

Burn Only High-Quality Wood
The Encore is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.
You’ll enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned, or cordwood dried more than two years. Do not burn construction materials; they often contain chemicals and
metals that can damage the catalytic combustor. The
wood should be 18-20” (400-500mm) in length.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and airdried outside under cover for at least one year.
If hardwood is not available, you can burn softwoods
which include tamarack, yellow pine, white pine, Eastern red cedar, fir, and redwood. These too should be
properly dried.
Store wood under cover to keep it dry. The longer it is
stored, the better heating and fireviewing performance
you will enjoy. Even for short-term storage, however,
keep wood a safe distance from the heater and keep
it out of the areas around the heater used for refueling
and ash removal.
2000956

located in the middle of the griddle.
Use the following temperature ranges as a guide to
operation:
• Readings in the 350-500°F (175-260°C) range
indicate low to medium heat output.
• 500-600°F (260-315°C) readings indicate medium heat output.
• Readings of 600-750°F (315-400°C) indicate
high heat output. Operating your Encore continuously

No single air control setting will fit every situation. Each
installation will differ depending on the quality of the
fuel, the amount of heat desired, and how long you wish
the fire to burn; outdoor air temperature and pressure
also affect draft.
The control setting also depends on your particular
installation’s “draft,” or the force that moves air from the
stove up through the chimney. Draft is affected by such
things as the length, type, and location of the chimney,
local geography, nearby obstructions, and other factors.
Refer to Pages 25-27 for details on how the installation
affects performance.

Encore Woodburning Stove
Too much draft may cause excessive temperatures in
the Encore, and could even damage the combustor.
On the other hand, too little draft can cause backpuffing
into the room and/or the “plugging” of the chimney or
combustor.
wood heater in a manner inconsistent with operating
instructions in this manual, or if the catalytic combustor
is deactivated or removed. The components of the catalytic combustion system in your Encore work together to
produce optimum conditions for secondary combustion.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrollable burn or a glowing-red stove part. A sign of inadequate draft is smoke leaking into the room through the
stove or chimney connector joints, low heat, and dirty
glass.
When the damper is closed, smoke travels through
the catalytic element, which causes ignition of smoke
at temperatures of 500-600°F (260-315°C), half the
temperature normally required for unaided secondary
combustion.
In some newer homes that are well-insulated and
weather-tight, poor draft may result from insufficient air
in the house. In such instances, an open window near
the stove on the windward side of the house will provide
the fresh air needed.
Another option for getting more combustion air to the
stove is to duct air directly from the outside to the stove.
In some areas provisions for outside combustion air are
required in all new construction.
Your Encore will accept a duct to deliver outside air for
combustion.
When first using the stove, keep track of the air control
settings. You will quickly find that a specific setting will
give you a fixed amount of heat. It may take a week or
two to determine the amount of heat and the length of
burn you should expect from various settings.
Most installations do not require a large amount of
combustion air, especially if adequate draft is available.
Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.
Use the following air control settings as a starting point
to help determine the best settings for your installation.
Each is described as a fraction of the total distance the
lever may be moved from right to left.

High-Efficiency Wood Burning with
Catalytic Combustion
An Encore leaves the factory with the combustor installed.
In the United States, it is against the law to operate this
22
The catalytic element is a ceramic “honeycomb” coated
with the catalytic material. The element is located in the
secondary combustion chamber, molded from a special
high-temperature insulating refractory material. The
chamber provides the correct environment necessary
for secondary combustion of the fuel (smoke).
Closing the damper exposes the smoke to the combustor. If the combustor is at least 600°F, it will begin to
burn the smoke.
Closing the stove damper may also reduce the draft, so
to avoid putting out the fire or deactivating the combustor, close the damper only when a fire is well-established. When starting a fire, wait until the fire is well
established and there is an ember bed of at least 3-4”
(76-102 mm) before closing the damper.
Never kindle a fire with colored paper or paper that
has colored ink or a glossy surface, and never burn
treated wood, garbage, solvents, or trash. All of these
may poison the catalyst and prevent it from operating
properly. Never burn cardboard or loose paper except
for kindling purposes. Never burn coal; doing so can
produce soot or large flakes of char or fly ash that can
coat the combustor and cause smoke to spill into the
room. Coal smoke also can poison the catalyst so that it
won’t operate properly.
In general, the fire must be sufficiently well-established
to ensure that catalytic activity is initiated. When first
starting a fire, a medium- to high- firing rate must be
maintained until the stove, catalyst, and fuel are all
stabilized at the proper operating temperatures.
Even though it is possible for the fire to get quite hot
within a few minutes after a fire is started, the combustor may stop working or the fire may go out if the fire
is allowed to die down immediately as a result of the
damper being closed. Once the combustor starts working, heat generated by burning the smoke will keep it
working.
To determine whether the combustor is operating, observe the amount of smoke leaving the chimney when
the damper is activated and when it is not. This procedure is described on Page 30.
Avoid using a full charge of very dry wood in the firebox. This may result in continuous very high temperatures in the secondary combustion area and damage

the combustor. Wood which has been split, and stored
under cover for more than 18 months may be considered very dry. Also, do not use a full load of dry slab
wood or scrap wood. For long burns, use a mix of dry
and moderately dry wood.
Conditioning Your Stove
Cast iron is extremely strong, but it can be broken with
a sharp blow from a hammer or from the thermal shock
of rapid and extreme temperature change.
The cast plates expand and contract with changes in
temperature. When you first begin using your Encore,
minimize thermal stress by allowing the plates to adjust
gradually during three or four initial break-in fires following Steps 1-3 below.

Some odor from the stove’s hot metal, the paint, and

Do not use chemicals or fluids to start the fire. Do
not burn garbage or flammable fluids such as gasoline, naptha, or engine oil.
NOTE: Some chimneys need to be “primed,” or
warmed up, before they will draw sufficiently to start
a fire. To correct this situation, roll up a couple pieces
of newspaper, place them on top of the kindling and
toward the back of the stove, light them, and close
the doors. This will encourage smoke to rise rapidly,
encouraging a good draft.
Starting and Maintaining a Wood Fire
1. Open the stove damper, and open the primary air
control fully.
2. Place several sheets of crumpled newspaper in the
stove. DO NOT use glossy advertisements or colored paper, as they can poison the catalyst. Place
on the paper six or eight pieces of dry kindling split
to a finger-width size, and on the kindling lay two or
three larger sticks of split dry wood approximately
1-2” (25-51 mm) in diameter.
Once the draft is established, open the front door and
light the rest of the fuel from the bottom. Do not light
the main bed of fuel until the chimney begins drawing,
and repeat the procedure as often as necessary if the
initial attempt is unsuccessful.
4. If your Encore has been broken-in previously using
Steps 1-3, continue to build the fire gradually. Add
larger wood with a diameter of 3-4” (76-102 mm).
Continue adding split logs of this size to the brisklyburning fire until there is a glowing ember bed at
least 3” (76mm) deep. A good ember bed is neces-

6. Adjust the air control for your desired heat output.
NOTE: Stove installations vary, and the operating
guidance given here is only a starting point. The draft
management information on Page 25 will explain in
detail how the features of your installation may help or
hinder good draft.
Refuel While the Embers Are Still Hot
CAUTION: The Encore will be hot while in operation. Keep children, clothing and furniture away.
Contact may cause skin burns.
Ash Disposal
You should remove ash before it reaches the top of the
ash pan. Check the level at least once a day. Every few
days, clear any ash from the outer edges of the firebox.
Most of the ash will fall through the grate. Slice or stir
the ash with a shovel or poker so that it falls through the
grate slots.
When reloading, best results will be achieved if you first
de-ash the stove by stirring the fuel bed to allow ash to
fall through the grate into the ash pan.
Do not break the charcoal into very small pieces or
pound or compress the charcoal bed.
Open
It is important that air can circulate through the charcoal
bed during the burn. Larger pieces of charcoal allow
more air to circulate under the wood, resulting in the
fire reviving more quickly.
For best results when refueling, wear stove gloves to
protect your hands, add fuel while the stove still has
plenty of glowing embers to re-kindle the fire, and
include some smaller pieces of wood in the new fuel
load to help the stove regain its operating temperature
quickly. Use this sequence as a guide to successful
refueling:
1. Open the damper.
2. De-ash the stove as described above. Open the
front doors and check the level of ash in the ash
pan. Empty the pan if necessary and replace it in the
stove. Close the front doors.
3. Open the griddle, load the wood (smaller pieces
first), and close the griddle.
4. Close the damper.
5. When the surface temperature reaches 450°F
(230°C), adjust the air control for the amount of heat
you desire.
NOTE: If the remaining charcoal bed is relatively thick
and if your fuel is well seasoned, it is possible to add
fresh fuel (smaller pieces first), close the door and
damper, and reset the primary air thermostat for the
desired heat output.

If the stove is in operation, close the ash door while
disposing of the ash.
Properly dispose of the ash in a metal container with
a tight-fitting lid. Store the container outdoors away
from all combustible material.
Return the ash pan to its original position in the
stove, and close and latch the ash door.
Do not operate the stove with the ash door open.
This will result in over-firing, and could cause damage to the stove, void the warranty, or even lead to a
house fire.
Empty the ash pan regularly, typically every one to
three days. The frequency will vary depending on how
you operate your Encore: ash will accumulate faster at
higher heat outputs.
Remove ash frequently and place it outdoors in a
metal container with a tight-fitting lid. Place the closed
container of ash on a noncombustible floor or on the
ground, well away from all combustible materials, pending final disposal. If the ash is disposed of by burial in
soil or otherwise locally dispersed, it should be kept in
the closed container until all cinders have thoroughly
cooled.
You can use wood ash as a garden fertilizer.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the stove; always remove
and dispose of the ash properly.
Draft Management
A stove is part of a system, which includes the chimney,
the operator, the fuel, and the home. The other parts of
the system will affect how well the stove works. When
there is a good match between all the parts, the system
works well.
Wood stove or insert operation depends on natural
(unforced) draft. Natural draft occurs when the smoke
is hotter (and therefore lighter) than the outdoor air at
the top of the chimney. The bigger the temperature
difference, the stronger the draft. As the smoke rises
from the chimney it provides suction or ‘draw’ that pulls
air into the stove for combustion. A slow, lazy fire with
the stove’s air inlets fully open indicates a weak draft.
A brisk fire, supported only by air entering the stove
through the normal inlets, indicates a good draft. The
stove’s air inlets are passive; they regulate how much
air can enter the stove, but they don’t move air into it.
Depending on the features of your installation - steel or
masonry chimney, inside or outside the house, matched
to the stove’s outlet or oversized - your system may
warm up quickly, or it may take a while to warm up and
operate well. With an ‘airtight’ stove or insert, one which
restricts the amount of air getting into the firebox, the
chimney must keep the smoke warm all the way to the
outdoors. Some chimneys do this better than others.
Here’s a list of features and their effects.
Masonry Chimney
Masonry is a traditional material for chimneys, but it
can perform poorly when it serves an ‘airtight’ stove.
Masonry is a very effective ‘heat sink’ - it absorbs a lot
of heat. It can cool the smoke enough to diminish draft.
The bigger the chimney, the longer it takes to warm up.
It’s often very difficult to warm up an outdoor masonry
chimney, especially an oversized one, and keep it warm
enough to maintain an adequate draft.
2000956
Steel Chimney
Most factory-made steel chimneys have a layer of
insulation around the inner flue. This insulation keeps
the smoke warm. The insulation is less dense than masonry, so a steel chimney warms up more quickly than
a masonry chimney. Steel doesn’t have the good looks
of masonry, but it performs much better.
Indoor / Outdoor location
Because the chimney must keep the smoke warm, it’s
best to locate it inside the house. This uses the house
as insulation for the flue and allows some heat release
into the home. An indoor chimney won’t lose its heat
to the outdoors, so it takes less heat from the stove to
heat it up and keep it warm.
Flue Sizing
The inside size of a chimney for an ‘airtight’ stove
should match the size of the stove’s flue outlet. When
a chimney serves an airtight, more is not better; in fact,
it can be a disadvantage. Hot gases lose heat through
expansion; if we vent a stove with a six-inch flue collar
(28 square inch area) into a 10 x 10” flue, the gases
expand to over three times their original size. This cools
the gases, which weakens draft strength. If an oversized flue is also outside the house, the heat it absorbs
gets transferred to the outdoor air and the flue usually
stays cool.
It’s common for a masonry flue, especially one serving
a fireplace, to be oversized for the stove. It can take
quite a while to warm up such a flue, and the results
can be disappointing. The best solution to an oversized
flue is an insulated steel chimney liner, the same diameter as the stove or insert’s flue outlet; the liner keeps
the smoke warm, and the result is a stronger draft. An
25
Encore Woodburning Stove
uninsulated liner is a second choice - the liner keeps
the smoke restricted to its original size, but the smoke
still must warm up the air around the liner. This makes
the warm-up process take longer.
Pipe & Chimney Layout
Every turn the smoke must take as it travels to the
chimney top will slow it down. The ideal pipe and chimney layout is straight up from the stove, to a completely
straight chimney. If you’re starting from scratch, use this
layout if possible. If the stovepipe must elbow to enter a
chimney, locate the thimble about midway between the
stove top and the ceiling. This achieves several goals:
it lets the smoke speed up before it must turn, it leaves
some pipe in the room for heat transfer, and it gives you
long-term flexibility for installing a different stove without
relocating the thimble.
There should be no more than 8’ (2.4m) of single-wall
stove pipe between the stove and a chimney; longer
runs can cool the smoke enough to cause draft and
creosote problems. Use double-wall stove pipe for long
runs.
Single venting
Each ‘airtight’ stove requires its own flue. If an airtight
stove is vented to a flue that also serves an open fireplace, or a leakier stove, it’s easier for the chimney draft
to pull air in through those channels than it is to pull air
through the airtight, and performance suffers. Imagine
a vacuum cleaner with a hole in the hose to see the effect here. In some cases the other appliance can even
cause a negative draft through the airtight, and result in
a dangerous draft reversal.
Creosote
Creosote is a by-product of slow wood-burning. It’s an
organic tar that can condense in the flue if it’s dense
in the smoke, and slow-moving, and cools off to less
than 290°F. Condensed creosote is volatile, and can
generate chimney fires if it gets hot enough. All the
features that affect chimney draft also affect creosote
condensation - so use whatever combination of installation features and operational steps will encourage good
draft and minimize creosote production.
Because letting the smoke cool off and slow down is
one of the keys to creosote production, it makes sense
to line a chimney to match the stove’s outlet size, for
safety reasons as well as performance. Canadian law
requires a matching liner to serve any stove or insert
vented through a fireplace chimney; in the US, the
National Fire Protection Association recommends one if
the flue is more than three times bigger (in square area)
than the outlet on the stove or insert. Some localities
enforce the NFPA guidelines as part of their building
codes.
26
Fuel
Even the best stove installation will not perform well
with poor fuel. The best fuel is hardwood that has airdried 12-18 months. Softwood burns, but not as long as
hardwood. Fairly ‘green’ wood has a good amount of
moisture in it; it will burn, but some of the heat potential
is used to drive the remaining moisture off the wood.
This reduces the amount that reaches your home and
can contribute to a creosote problem. There are moisture meters available for firewood; you can also judge
your wood by its appearance and weight. If you get it
green, lift a piece and get a sense of its weight; it can
lose a third or more of its weight as it dries. Also look at
the ends of a log; as it dries it shrinks and often cracks.
The more weathered and cracked a piece is, the drier
it is.
Dry wood burns readily with a good chimney draft. But
with modern stoves, especially catalytic ones, the wood
can be too dry. While extra-dry wood has little creosote
in it, the remainder can ‘gas out’ from the wood quickly
and densely enough to overload the catalytic burner.
If you hear a rumbling or roaring noise, like a propane
torch, from the stove, that is a sign the catalyst is seriously overfiring. The catalyst is a platinum film on a
ceramic base; the metal can get to higher temperatures
than the ceramic can take, and overfiring the catalyst
can break it. Dry wood can also burn out faster than
you want. If your dry wood burns out too quickly or
overloads the catalyst you can mix in greener wood to
slow the fire down.
Back-puffing
Back-puffing results when the fire produces volatile
gases faster than the chimney draft pulls them out of
the firebox. The gases back up in the firebox till they’re
dense enough and hot enough to ignite. If your stove
back-puffs, you should open the damper to let the
smoke rise to the flue more quickly, let more air into the
firebox, and avoid big loads of firewood. You should
always see lively, dancing flames in the firebox; a lazy,
smoky fire is inefficient, can lead to back-puffing, and
can contribute to creosote buildup in the chimney.
Draft Testing
An easy way to test your chimney draft is to close the
stove’s damper, wait a few minutes to let the airflow
stabilize, then see whether you can vary the strength
of the fire by swinging the air control open and closed.
Results are not always instant; you may need to wait
a few minutes for a change in the air control setting to
have an effect on the fire. If there’s no change, then the
draft isn’t strong enough yet to let you close the damper,
and you’ll need to open it for a while longer and manage
the fire with the air inlet until the draft strengthens. If you
2000956
Encore Woodburning Stove
keep track of your burning habits and relate them to their
effects on the stove’s operation, you’ll be rewarded with
good performance and a safe system.
Negative Pressure
Good draft also depends on a supply of air to the stove;
a chimney can’t pull in more air than is available to it.
Sluggish draft results when a house is tight enough to
prevent the ready flow of air to the stove, or by competition between the stove and other equipment that sends
indoor air outside - especially power-driven equipment
like range hoods, clothes dryers, etc. If the chimney
draws well with all other equipment turned off (or
sealed, in the case of fireplaces and/or other stoves),
then you simply need to be careful with timing the use
of the other gear. If you need to crack a nearby window
or door to enable the chimney to pull well, that’s a sign
that you should install an outside-air intake to bring
combustion air directly to the stove. For most of our
stoves we carry adapters to attach to the stove to connect an air duct for outdoor combustion air.
Conclusion
Wood-burning is an art rather than a science. Once the
stove and chimney system are in place, you can only
vary your technique, mostly your timing, to achieve
good results. If you keep track of your burning habits
and relate them to their effects on the stove’s operation,
you’ll be rewarded with good performance and a safe
system.
Maintenance
Keep Your Stove Looking New
and Working Its Best
Let the fire in the stove go out and allow the stove to
cool completely before beginning any maintenance
procedure.
Care of the Cast Iron Surface
An occasional dusting with a dry rag will keep the painted
cast iron of your Encore looking new.
The stove’s paint can be touched up as needed. First,
mask the areas, such as enamelled parts, glass, or
handles, around the spot to be painted. Clean the spot
with a wire brush. Remove the griddle and set it aside.
Then, touch up the stove with Vermont Castings’ high
temperature stove paint. Apply the paint sparingly; two
light coats of paint are better than a single heavy one.
Care of the Porcelain Enamel Surface
Use a dry or slightly damp rag or soft brush to remove
spills or stains. For difficult jobs that require a cleaning
agent, use only a kitchen appliance cleaner or polish
recommended for use on enamel surfaces.
Cleaning the Glass
Most of the carbon deposits on the glass will burn off
during hot fires.
However, the ash residue that accumulates on the
glass surface should be removed regularly to prevent
etching. To clean the glass, follow this procedure:
• Be sure the glass is completely cool.
• Clean the glass with water or a cleaner made espe•
•
cially for this purpose. Do not use abrasive cleaners.
Rinse the glass thoroughly.
Dry the glass completely.
Replace Broken Glass Immediately
Do not operate your stove if the glass in the doors is
damaged.
If you need to replace the glass, use only the high temperature ceramic glass supplied by Vermont Castings.
Do not use substitutes. Be sure to specify left or right
glass; the panels are not interchangeable.

Removing the Glass
The left door is slightly different from the right in that
one of its retainer clips is located under the door manifold.
1. Remove the right and left door assemblies by raising
the door until the lower hinge pin clears its drilling;
then, angle the door bottom slightly outward and
pull down to release the upper hinge pin. Place the
doors face down on a padded work surface.
2. Remove the screws that hold the retainer clips in
place, and remove the clips. On the right door, remove the Phillips head machine screw that secures
the door manifold to the upper right of the door (as it
faces you). Swing the door manifold out of your way
and remove the clip beneath it as well.
3. Carefully lift the broken glass panel from the door.
Installing the Glass
Check the gasket around the window; it should be soft
and resilient so the glass will seal properly against the
door. Replace the gasket if it has hardened or if it is
compressed.
1. Center the first pane of glass on the gasket. Be sure
to place the glass so the infrared reflective coating is
on the exterior side.

Check the Operation
of the Primary Air Shutter
The primary air shutter is located at the back of the ash
drop and is visible from the back of the stove. (Fig. 45)
The shutter must open and close freely when you move
the thermostat lever. If it does not, remove any obstruction. If you need assistance, consult your local Vermont
Castings Authorized Dealer.
Do not change the adjustment of the cable in an attempt to gain increased firing. The air shutter controls
how much air can enter the stove, but chimney draft
is the force that pulls air into the stove. If changing the
thermostat handle position does not lead to changes in
the fire’s intensity, it is probably due to weak chimney
draft (in the case of a weak fire you can’t increase) or
an air leak in the stove (in the case of a fire you can’t
decrease).

3. Replace the doors on the stove. Remove the griddle
so you can reach in through the opening to position the manifold. Move the door manifold as high
as possible without actually touching the upper air

How to Adjust the Door Latches
The Encore’s front doors, as well as its ash pan door,
should close securely to prevent accidental opening and to keep air from leaking into the stove. On
adequately adjusted doors, the handles should resist
slightly as they are turned to the closed position and the
doors themselves should be drawn slightly toward the
stove.
Over time, the gasket around the doors will compress
and the latch may need adjustment.
To adjust the handle on the front doors, open the
door on which the handle is mounted and rotate the
handle one full turn counterclockwise. Since this handle
is threaded into the front door, a complete revolution will
adjust it enough so the doors close securely.
To adjust the latch on the ash pan door, loosen the
small lock nut, rotate the striker screw a half-turn, and
re-tighten the small lock. Hold the striker screw to keep
it from turning as you tighten the lock nut. Make repeated small adjustments until the setting is right.
The Catalytic Element
Inspection and Cleaning
This wood heater contains a catalytic combustor, which
needs periodic inspection and replacement for proper
operation. In the United States it is against the law to
operate this wood heater in a manner inconsistent with
the operating instructions in this manual, or if the catalytic element is deactivated or removed.
2000956
ST531
Fig. 47 Turn the door latch striker screw in or out to tighten or
loosen the door latch.
ST531
Under normal operating conditions,
the catalytic comDoor Pawl
bustor should remain active for two to six years (de11/00
pending on the amount of wood burned). However, it
is important to monitor the combustor periodically to
ensure that it is functioning properly, as well as 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.
Inspect the combustor “in place” for fly ash accumulation and physical damage three times per year. Do not
remove the combustor unless a more detailed inspection is warranted because of diminished performance
as outlined below.
The refractory package that houses the catalytic combustor should be inspected annually for a buildup of fly
ash and cleaned if necessary. This may be done when
you examine the combustor.
When to Suspect a Combustor Problem
The best way to evaluate the performance of your
Encore’s combustor is to observe the amount of smoke
leaving the chimney — both when the combustor has
achieved “light-off” and when it has not. Follow these
steps:
• With a fire going and the combustor properly activated, with the damper closed to route smoke through
it as described in the Operation Section, go outside and
observe the smoke leaving the chimney.
• Then, open the stove damper and once again
check the smoke leaving the chimney. Significantly
more smoke should be seen when the stove damper is
open and exhaust does not pass through the combustor. Be careful not to confuse smoke with steam from
wet wood, however. Steam dissipates in the air quickly;
smoke does not.
29
Encore Woodburning Stove
If this test indicates a problem, consider other possible
factors as well, such as the time of year or a change in
the quality of your fuel. In spring and fall, draft is weaker
than it is in colder winter weather, and fires can burn
sluggishly. Small, hot fires are a good solution under
these conditions.
Refractory Access Cover

Burning “green” (insufficiently seasoned) wood will result in poorer performance than when burning properly
seasoned fuel. You may have to run your stove hotter
(more air) to achieve good performance with green or
wet wood.
Also, consider any changes in your operating routine.
Once you have ruled out any other possible causes for
a decline in performance, you may inspect the combustor.
Inspecting the Combustor
1. Release the hood from the fireback by swinging the
hood upward and then sliding it to either side. (Fig.

6. Check the combustor’s honeycomb-like element
for a buildup of fly ash. If any is evident, take the
combustor outside and clean it by blowing air gently
through it.
7. Inspect the element for damage or degradation.
Although small hairline cracks will not affect performance, the element should be essentially intact.
If the element is broken in pieces or has sections

missing, it should be replaced. Call your local Vermont Castings’
Authorized Dealer for a replacement

probe within the combustion chamber. The probe should extend 1” to 1¹⁄₂” (25-38mm) into
the chamber and show no signs of deterioration, such
as warping, corrosion, or short length. (Fig. 51) A damaged secondary air probe can affect catalytic performance. If the probe needs replacement, contact your
local dealer.

8. If the element is in good condition and clean, re-install it in the stove and replace the refractory access
cover.
9. Replace the fireback, install the two wedges, and
replace the cast iron hood.
10. Clean the chimney and chimney connector.
Operate the stove in your typical manner for two weeks,
inspecting the chimney and the chimney connector
frequently during this period.
The procedure for replacing gaskets is the same regardless of the gasket location. Follow these steps:
1. Remove the existing gasket by grasping an end and
pulling firmly.
2. Use a wire brush or the tip of a screwdriver to clean
the channel of any remaining cement or bits of gasket.
(Fig. 54) Remove stubborn deposits of cement with a
cold chisel if necessary.
If creosote is not building up as fast, it is likely the
performance change was caused by fly ash deposits
on the catalytic element. However, continue the inspections of the chimney system for a few weeks to ensure
proper performance continues.
If you continue to find a significant creosote buildup or if
you continue to see excessive smoke from the chimney,
the catalytic element will need to be replaced. Contact
your nearest Vermont Castings’ Authorized Dealer for
information about a replacement element.
NOTE: Use only the replacement catalyst supplied by a
Vermont Castings dealer.
Replace the Stove Gaskets as Needed
Your Encore uses rope-type fiberglass gaskets to make
a tight seal between some parts. With use, particularly
on those parts that move, gaskets can become brittle
and compressed and can begin to lose their effectiveness. These will need periodic replacement.
All of the gaskets are made of fiberglass. The sizes of
replaceable gasket are listed below, along with their
applications.

sure to follow the standard safety procedure for working
with dusty materials: Wear safety goggles and a dust
mask.

8. Clean any excess cement from around the channel, then let the cement that holds the new gasket dry
thoroughly.
Adjust the Door If Necessary
The stove’s door(s) may need adjustment after you
have regasketed it. Initially, it may require loosening to
accommodate the new gasket; after a few weeks, it
may need tightening to compensate for compression of
the new gasket. The directions for adjusting the doors
are on Page 29-30.
Permanent Encore Gaskets
Other gaskets form seals between non-moving parts,
but these are not subject to the same wear and deterioration as gaskets on moving parts. It is unlikely that
you will ever need to replace these gaskets unless the
involved parts are disassembled and then put back
together. If this is the case, the job should be done only
by a qualified service technician.
5/16” diameter gasket seals the following parts:
•The flue collar to the stove back
•The lower fireback to the sides
The Chimney System
Creosote
Your Encore is designed to reduce creosote build-up
significantly. However, regular chimney inspection and
maintenance must still be performed. For safety, good
stove performance, and to protect your chimney and
chimney connector, inspect your chimney and chimney
connector on a regular schedule. Clean the system if
necessary. Failure to keep the chimney and connector
system clean can result in a serious chimney fire.
When wood is burned slowly, it produces tar, organic
vapors and moisture that combine to form creosote.
The creosote vapors condense in the 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 within the
flue system that can damage the chimney and overheat
adjacent combustible material. If a significant layer of
creosote has accumulated —1/8” (3mm) or more — it
should be removed to reduce the risk of a chimney fire.
If you do experience a chimney fire, act promptly
to:
• Close the damper and thermostat lever.
• Get everyone out of the house.
• Call the Fire Department.
32
You should inspect the system every two weeks during
the heating season as part of a regular maintenance
schedule. To inspect the chimney, let the stove cool
completely. Then, using a strong light, sight up through
the flue collar into the chimney flue. If it is not possible
to inspect the flue system in this fashion, the stove must
be disconnected to provide better viewing access.
Clean the chimney using a brush the same size and
shape as the flue liner. Flexible fiberglass rods are used
to run the brush up and down the liner, causing any
deposits to fall to the bottom of the chimney where they
can be removed through the clean-out door.
Clean the chimney connector by disconnecting the sections, taking them outside, and removing any deposits
with a stiff wire brush. Reinstall the connector sections
after cleaning, being sure to secure the joints between
individual sections with sheet metal screws.
If you cannot inspect or clean the chimney yourself,
contact your local Vermont Castings’ Dealer or a professional chimney sweep.
Annual Maintenance
Every Spring, at the end of the heating season, perform
a thorough cleaning, inspection and repair:
• Thoroughly clean the chimney and chimney connector.
• Inspect the chimney for damage and deterioration.
Replace weak sections of prefabricated chimney.
Have a mason make repairs to a masonry chimney.
• Inspect the chimney connector and replace any
damaged sections.
• Check gasketing for wear or compression, and replace if necessary.
• Inspect and clean the catalytic element, and vacuum
out the ash at the bottom of the back plate after removing the lower fireback. Lightly clean the refractory assembly that houses the element but be careful
not to damage the refractory material, which is very
fragile.
• Check door and damper handles for tightness. Adjust if needed.
• Check heat shield screws. Tighten as necessary.
• Clean dust from the inner sides of bottom, rear and
connector heat shields.
• Remove ashes from the ash pan and replace with
moisture absorbing material (such as cat litter) to
keep the stove interior dry.
• Touch up the paint on black stoves.

Encore Woodburning Stove
Appendix: Catalytic Combustor
In any chemical reaction, including the combustion
process, there are certain conditions which must be
met before the reaction can take place. For example, a
reaction may require a certain temperature, or a certain
concentration of the reactants (the combustion gases
and oxygen), or a certain amount of time. Catalysts,
though not changed themselves during the reaction,
have the ability to act at a molecular level to change
these requirements. In the Encore’s secondary combustion chamber the catalyst reduces the temperature
at which secondary combustion can start from the 1000
- 1200°F (540 - 650°C) range to the 500 - 600°F (260
- 315°C) range, increasing efficiency, and reducing
creosote and emissions.
The catalytic reaction does have some limitations of its
own. Primary among these is that the reactants (the
gases) come into close physical contact with the catalyst itself.
To ensure the necessary contact, the catalytic element
in your Encore is composed of a ceramic base in the
shape of a honeycomb. Each of the honeycomb’s many
surfaces carries a coating of the catalyst (usually a
noble metal such as platinum or palladium). The large
surface area exposed in this form ensures that the combustion gases have the greatest opportunity to come in
contact with the catalyst.
Loss of catalytic activity will be apparent in several
ways. First you may notice an increase in fuel consumption. Second, there will be a visible increase in the
rate at which creosote builds up in your chimney connector system. You may also notice a heavy discharge
of smoke from the chimney. There are a number of
catalytic problems which can cause loss of activity:
Blockage
While the honeycomb pattern ensures good contact, it
also increases the resistance to flow of the combustion
gases, and, because of the many surfaces, provides
more places for creosote and fly ash to deposit. It is
important to follow the operating instructions in order
to minimize these deposits, and to periodically inspect
your catalyst for signs of blockage.
Masking and Poisoning
While the catalyst itself does not enter into the combustion process, certain elements, such as lead and sulfur,
can attach to the active sites on the surface of the honeycomb. Though the catalyst is still there, it is covered,
or masked, by the contaminant, and cannot function. To
avoid this situation, it is important not to burn anything
in your Encore that is a source of these contaminants.
Particularly avoid painted or treated wood, coal, household trash, colored papers, metal foils, or plastics.
Chemical chimney cleaners may also contain harmful
elements. The safest approach is to burn only untreated, natural wood.
Flame Impingement
The catalytic element is not designed for exposure to
direct flame. If you continually overfire your Encore, the
chemistry of the catalyst coating may be altered, inhibiting the combustion process.
Thermal degradation of the ceramic base may also occur, causing the element to disintegrate. Stay within the
recommended guidelines of the Operation section.
Mechanical Damage
If the element is mishandled, damage may occur.
Always treat the element carefully. Remember the catalyst is made of a ceramic material; treat it as you would
fine china. Hairline cracks will not affect the performance of the catalyst, as long as the steel sleeve holds
the element in the proper position.
Peeling
The surface coat may peel if the catalytic element is
frequently subjected to excessive temperatures. Follow
the operating instructions carefully to avoid this type of
damage.
General
Every Vermont Castings’ Encore is equipped with either
a Corning “Long-Life”® or a Technical Glass Products
“Honeycomb”® combustor. The products are equivalent.
If you must ship your catalytic element for any reason,
remember its fragile nature. Place the element in a
plastic bag, and package it with a generous amount of
shock absorbing material.

Warranty
Limited 3 Year Warranty
CFM Corporation warrants that this woodburning stove will be free
of defects in material and workmanship for a period of three years
from the date you receive it, except that the catalyst, thermostat
assembly, handles, glass door panels, cement, and gasketing shall
be warranted as described below.
CFM Corporation will repair or replace, at its option, any part found
to be defective upon inspection by a Vermont Castings, Authorized
Dealer. The customer must return the defective part or the stove, with
shipping prepaid, to the Authorized Dealer or pay for any Authorized
Dealer in-home travel fees or service charges for in-home repair work.
It is the dealer’s option whether the repair work will be done in the customer’s home or in the dealer’s shop. If, upon inspection, the damage
is found to be the fault of the manufacturer, repairs will be authorized at
no charge to the customer for parts and/or labor.
Any woodburning stove or part thereof that is repaired or replaced
during the limited warranty period will be warranted under the terms of
the limited warranty for a period not to exceed the remaining term of the
original limited warranty or six (6) months, whichever is longer.
Limited 1 Year Warranty
The following parts of the woodburning stove are warranted to be free
of defects in material and workmanship for a period of one year from
the date you receive it: The thermostat assembly, handles, glass door
panels, cement, and gasketing. Any of these items found to be defective will be repaired or replaced at no charge, upon the return of the
part with postage prepaid to a Vermont Castings Authorized Dealer.
Any part repaired or replaced during the limited warranty period will
be warranted under the terms of the limited warranty for a period not
to exceed the remaining term of the original limited warranty or six (6)
months, whichever is longer.
Limited Catalyst Warranty
The catalyst will be warranted for a six year period as follows: If the
original catalyst or a replacement catalyst proves defective or ceases to
maintain 70% of its particulate emission reduction activity (as measured
by an approved testing procedure) within 24 months from the date the
stove is received, the catalyst itself will be replaced free.
From 25 - 72 months a pro-rated credit will be allowed against a replacement catalyst and the cost of labor necessary for its installation at
the time of replacement.
For stove purchases made after June 30, 1990, a third year
(25 - 36 months) of no charge replacement will be made when combustor failure is due to thermal degradation of the substrate (crumbling of
ceramic material). The customer must pay for any in-home travel fees,
service charges, or transportation costs for returning the stove to the
Authorized Dealer.

Exclusions & Limitations
1. This product must be installed or serviced by a qualified installer,
preferably NFI or WETT (Canada) certified, as prescribed by the
local jurisdiction. It must be installed and operated at all times in accordance with the Installation and Operating instructions furnished
with the product. Any alterations, willful abuse, accident or misuse of
the product shall nullify this warranty.
2. This warranty is transferable; however, proof of original retail purchase is required.
3. This warranty does not cover misuse of the stove. Misuse includes
overfiring which will result if the stove is used in such a manner as
to cause one or more of the plates to glow red. Overfiring can be
identified later by warped plates and areas where the paint pigment
has burned off. Overfiring in enamel fireplaces is identified by bubbling, cracking, chipping and discoloration of the porcelain enamel
finish. CFM Corporation offers no warranty on chipping of enamel
surfaces. Inspect your woodburning stove prior to accepting it for
any damage to the enamel.
4. This warranty does not cover misuse of the stove as described
in the Owner’s Guide, nor does it cover an stove which has been
modified unless authorized by a CFM Corporation representative in
writing. This warranty does not cover damage to the stove caused
by burning salt saturated wood, chemically treated wood, or any fuel
not recommended in the Owner’s Guide.
5. This warranty does not cover a stove repaired by someone other
than a Vermont Castings Authorized Dealer.
6. Damage to the unit while in transit is not covered by this warranty
but is subject to a claim against the common carrier. Contact
Vermont Castings Authorized Dealer from whom you purchased
your stove or CFM Corporation if the purchase was direct. (Do not
operate the stove as this may negate the ability to process the claim
with the carrier.)
7. Claims are not valid where the installation does not conform to local
building and fire codes or, in their absence, to the recommendations
in our Owner’s Guide.
8. The salt air environment of coastal areas, or a high-humidity environment, can be corrosive to the porcelain enamel finish. These
conditions can cause rusting of the cast iron beneath the porcelain
enamel finish, which will cause the porcelain enamel finish to flake
off. This warranty does not cover damage caused by a salt air or
high-humidity environment.
9. CFM Corporation shall have no obligation to enhance or update any
unit once manufactured.
IN NO EVENT SHALL CFM CORPORATION BE LIABLE FOR INCIDENTAL AND CONSEQUENTIAL DAMAGES. ALL IMPLIED WARRANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS, ARE LIMITED TO THE DURATION OF
THIS WRITTEN WARRANTY. THIS WARRANTY SUPERCEDES ALL
OTHER ORAL OR WRITTEN WARRANTIES.
Some states do not allow the exclusion or limitations of incidential and
consequential damages or limitations on how long an implied warranty
lasts, so the above limitations may not apply to you. This warranty gives
you specific rights and you may have other rights which vary from state
to state.
How to Obtain Service
If a defect is noted within the warranty period, the customer should
contact a Vermont Castings Authorized Dealer or CFM Corporation if
the purchase was direct with the following information:
1. Name, address, and telephone number of the purchaser.
2. Date of purchase.
3. Serial number from the label on the back.
4. Nature of the defect or damage.
5. Any relevant information or circumstances, e.g., installation,
mode of operation when defect was noted.
A warranty claim will then start in process. CFM Corporation reserves
the right to withhold final approval of a warranty claim pending a visual
inspection of the defect by authorized representatives.
