SAFETY NOTICE: If your stove is not properly in

­stalled, operated and maintained, a house fire may
result. For safety, follow all installation, operation
and maintenance directions. Contact local building
officials about restrictions and installation inspec

-

tion requirements in your area.

Before you begin an installation, review your plans to
be certain that:

• Your stove and chimney connector will be far

enough from combustible material to meet all clear­ance requirements.

• The floor protector is large enough and is construct-

ed properly to meet all requirements.

• You have all necessary permits from local authori-

ties.

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
the stove indicates that the Madison has been tested
to current UL and ULC standards by CSA. Clearance
and installation information is also printed on the label.
Local authorities generally will accept the label as
evidence that, when the stove is installed according
to the information on the label and in this manual, the
installation meets codes and can be approved. Codes,
however, 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 questions about installation, refer
to the National Fire Protection Association’s publication

ANSI/NFPA 211–1988 Standard for Chimneys, Fire­places, Vents and Solid Fuel Burning Appliances. In
Canada, the equivalent publication is CSA CAN-B365,
Installation Code for Solid Fuel Burning Appliances and
Equipment. These standards are the bases 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:
instructions may result in a dangerous situation, in­cluding a chimney or house fire. Follow all instruc
tions exactly and do not allow makeshift compro­mises to endanger property and personal safety.

Chimneys

Your stove must be connected either to a sound
masonry chimney that meets local codes, to a relined
masonry chimney that meets local codes, or to an
approved prefabricated metal chimney. Whichever of
those types you use, the chimney and chimney connec­tor must be in good condition and kept clean.

If you use an existing masonry chimney, it must be
inspected to ensure safe condition before the stove is
installed. Your local professional chimney sweep, build­ing inspector, or fire department official will be able to
make the inspection or direct you to someone who can.

The chimney should extend at least 3’ (914mm) above
the highest point where it passes through a roof, and at
least 2’ (610mm) higher than any portion of a building
within 10’ (3m).

To assure proper draft and good performance, any
chimney used with this stove should extend at least 16’
(5m) above the flue collar of the stove.

Masonry Chimneys

An existing masonry chimney must be inspected to con­firm that it has a lining. Do not use an unlined chimney.
The chimney also should be examined for cracks, loose
mortar, other signs of deterioration, and blockage. Re­pair any defects before the chimney is used with your
stove.

Masonry Chimneys, cont’d.

• 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 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 precast refractory tiles, stainless
steel pipe, or a code-approved, “poured-in-place”
liner. The chimney clean-out door must seal tightly to
ensure a good draft.

Prefabricated Chimneys

A prefabricated metal chimney must be one that is test­ed and listed for use with solid-fuel burning appliances
to the High-Temperature (H.T.) Chimney Standard
UL-103-1985 (2100° F.) for the United States, and High
Temperature (650°C) Standard ULC S-629 for Canada.

Chimney Size

This Madison is approved for venting into a masonry
chimney with a nominal flue size of 8” x 8” (203 x
203mm), and into a round flue size of 8” (203mm) or
6” (152mm). It 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 they are located
outside the home. Such large chimneys may need to be
insulated or relined for proper stove performance.

DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.

NOTE: DO NOT VENT THIS STOVE INTO A FAC
TORY-BUILT (ZERO-CLEARANCE) FIREPLACE.
THIS STOVE HAS NOT BEEN TESTED AND
LISTED FOR THAT TYPE OF INSTALLATION.

Chimney Connector Guidelines

A chimney connector is the double-wall or single-wall
pipe that connects the stove to the chimney. The chim­ney itself is a masonry or prefabricated structure that
encloses the flue. Chimney connectors are used only
to make the connection from the stove to the chimney.
They are for interior use only.

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,
and should be 6” (150mm) in diameter. Do not use
galvanized chimney connector; it cannot withstand the
high temperatures that can be reached by smoke and
exhaust gases, and may release toxic fumes under high
heat.

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 recommen­dations in the sec­tion following on Wall
Pass-throughs. Do
not pass the connec­tor through an attic, a
closet or any similar
concealed space. The
whole chimney con­nector should be ex­posed and accessible
for inspection and cleaning.

Install the single wall chimney connector not less than
23” (585mm) from the ceiling. Keep it as short and
direct as possible, with no more than two 90 degree
turns. If possible, use 45 degree elbows. Slope horizon­tal runs of connectors upward 1/4” per foot (20mm per
meter) going from the stove toward the chimney. The
recommended maximum length of a horizontal run is 3
feet (1 meter), and the total length of chimney connec­tor should be no longer than 8’ (2.5m).

In cathedral ceiling installations, extend the prefabricat­ed chimney downward to within 8’ (2.5m) of the stove.

SAFETY NOTE: ALWAYS WEAR GLOVES AND PRO
TECTIVE EYEWEAR WHEN DRILLING, CUTTING OR
JOINING CHIMNEY CONNECTOR SECTIONS .

Vermont Castings Madison

Double-wall Chimney Connectors

The Madison is approved for installation in the U.S.
and Canada with double-wall chimney connectors
that have been tested and listed for use with solid-fuel
burning appliances by a recognized testing laboratory.

Follow the instructions for assembling and installing
double-wall connectors provided by the manufacturer
of the double-wall chimney. To ease assembly and
help assure safety, use chimney components manufac­tured by a single source.

NOTE: For installations using double-wall connec­tors, minimum clearances must conform to those
listed in the clearance chart on Page 12.

Single-wall Chimney Connectors

• Beginning at the flue collar of the stove, assemble

the chimney connector. Insert the first crimped end
into the stove’s flue collar, and keep each crimped
end pointing toward the stove. Using the holes in
the flue collar as guides, drill 1/8” (3mm) holes in
the bottom of the first section of chimney connector
and secure it to the flue collar with three #10 x 1/2”
sheet metal screws.

• Secure each joint between sections of chimney

connector, including telescoping joints, with at least
three sheet metal screws. The predrilled holes in
the top of each section of chimney connector serve
as guides when you drill 1/8” (3mm) holes in the
bottom of the next section.

• Secure the chimney connector to the chimney. In-

structions for various installations follow.

• Be sure the installed stove and chimney connec-

tor are correct distances from nearby combustible
material.

NOTE: Special slip pipes and thimble sleeves that form
telescoping joints between sections of chimney con­nector are available to simplify assembly. Slip pipes
eliminate the need to cut individual connector sections.
Consult your local dealer about these special connec­tor sections.

Securing the Single-wall Connector to a

Prefabricated Chimney

Follow the installation instructions of the chimney
manufacturer exactly.

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 attach directly to the chimney or to the chimney’s
ceiling support package. The bottom of the adapter is
secured to the chimney connector.

The adapter forms a union between the chimney and
chimney connector that ensures any soot or creosote
falling from the inner walls of the chimney will stay
inside the chimney connector.

Securing the Single-wall Connector to a

Masonry Chimney

The Madison may be connected to either a freestand­ing masonry chimney or to a fireplace masonry chim­ney.

Freestanding Installations

If the chimney connector must pass through a combus­tible wall to reach the chimney, follow the recommenda­tions for Wall Pass-Through construction on Pages 7-8.
The opening through the chimney wall to the flue - the
“breech” – must be lined with a ceramic or metal
thimble which is securely cemented in place. (Fig. 5)

A metal pipe section called the “thimble sleeve,” slightly
smaller in diameter than standard connector and the
thimbles, will allow the removal of the chimney connec­tor system for inspection and cleaning. Thimble sleeves
are available from your local dealer.

To install a thimble sleeve, slide it into the breech until
it is flush with the inner flue wall. Be sure that it does
not extend into the flue passage where it could interfere
with the draft.

The thimble sleeve should protrude 1-2” (25-51mm)
into the room. Use furnace cement and thin gasketing
to seal the sleeve in place in the thimble. Secure the
chimney connector to the outer end of the sleeve with
sheet metal screws.

Keep sleeve

30001453

Connection Above the Fireplace

In this installation, the chimney connector enters the
fireplace flue through a thimble located above the
fireplace. (Fig. 6) The liner of the fireplace chimney
should extend at least to the point at which the chimney
connector enters the chimney. Follow all the guidelines
for installing a chimney connector into a freestanding
masonry chimney, and pay special attention to these
additional points:

• The stove and chimney connector clearances to

combustible mantel and trim materials are the same
as clearances to combustible walls. If necessary,
use a combination of mantel, trim, and connector
heat shields to provide the required clearances.
Refer to Page 12.

• Double-check connector clearance to the ceiling.

• The fireplace damper must be closed and sealed to

prevent room air from being drawn up the flue which
could reduce performance. However, it must be
possible to reopen the damper to inspect or clean
the chimney.

• Floor protection requirements also apply to fireplace

installations.

Wall Pass-throughs

Whenever possible, design the installation so that the
connector does not pass through a combustible wall.
If you must include 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.

Consult with your dealer regarding special connection
components available for use as wall pass-throughs.
Use only parts that have been tested and listed for use
as a wall pass-through.

U.S. Requirements:

The National Fire Protection Association (NFPA) has
established guidelines for use in the United States for
passing chimney connectors through combustible walls.
Many building code inspectors follow these guidelines.

Figure 7 shows one NFPA-approved method. All com­bustible material in the wall is cut away to provide 12”
(305mm) clearance to the connector. Brick and mortar
are used to enclose the clearance area.

Alternate methods approved by the NFPA:

• Using a section of double-wall chimney with a 9”

(229mm) clearance to combustibles. (Fig. 8)

• Placing a chimney connector pipe inside a steel

double-wall ventilated thimble, which is then sepa­rated from combustibles by 6” (152mm) of fiberglass
insulating material. (Fig. 9)

• Placing a chimney connector pipe inside a section of

9” (230 mm) diameter, solid-insulated, factory-built
chimney, with two inches of air space between the
chimney section and combustibles. (Fig. 10)

Canadian Requirements:

In Canada, the Canadian Standards Association has
established specific guidelines regarding wall pass­though design. Figure 11 shows one approved method
in which all combustible material in the wall is cut away
to provide the required 18” (457mm) clearance around
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” (25mm) clear of the wall. Your local
dealer or your local building inspector can provide de­tails of other approved methods of passing a chimney
connector through a combustible wall.

In Canada, this type of installation must conform to
CAN/CSA-B365, Installation Code for Solid Fuel Burn­ing Appliances and Equipment.

Floor Protection

A tremendous amount of heat radiates from the bottom
plate of your Madison. The floor area directly under and
around the stove will require protection from radiant
heat as well as from stray sparks or embers that may
escape the firebox.

Heat protection is provided through the use of a Ver
mont Castings Bottom Heat Shield #1892. Spark and
ember protection must be provided by a floor protector
constructed with noncombustible material as specified.

Most installations will require that the bottom heat shield
be attached. Only when the stove is placed on a complete
ly 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” non-asbestos
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
United States and Canada as follows:

For U.S. installations the floor protector is required
under the stove and must extend at least 18” from the
front of the stove (“D”, Fig. 12), at least 4” from the right
side and rear (“C”, Fig. 12) and 16” from the left side
(“E”, Fig. 12). It must also extend under the chimney
connector and 2” to either side (“F”, Fig. 12).

To meet these requirements, a floor protector must be
at least 48” wide (“A”,Fig. 12) and 48” deep (“B”,Fig. 12)

In Canada, a noncombustible floor protector is required
under the heater also. The floor protector must extend
18” (457mm) to the front (D), and 8” (203mm) from the
right side (C) and rear (C) and 18” (457mm) from left
side (E).

be at least 54” (1372mm) wide (“A”,Fig. 12) and 52”
(1320mm) deep (“B”, Fig. 12).

Fireplace Hearth Protection

Do not assume that your fireplace hearth is completely
noncombustible. Many fireplace hearths do not satisfy
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 is readily conducted by brick or concrete, 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.

For all fireplace installations, follow the floor protection
guidelines described above.

Keep in mind 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: 18” (460mm)
from the front in the United States and 18” (460mm)
from the front in Canada.

Hearth rugs do not satisfy the requirements for floor
protection as they are only fire-retardant, not fire proof.

Clearance to Surrounding

Combustible Materials

When the stove is operating, both the stoveplate and
the chimney connector radiate heat in all directions. A
safe installation requires that adequate clearance be
maintained between the stove and nearby combustible
materials to ensure that those materials do not over­heat.
Clearance is the distance between either your stove
or chimney connector, and nearby walls, floors, the
ceiling, and any other fixed combustible surface. Keep

furnishings and other combustible materials 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. Keep this area
empty of any combustible material.

Safe Ways to Reduce Clearances

The Madison clearance requirements, listed and
diagramed on Pages 12-13, have been established
through testing to UL and ULC standards to meet most
installation configurations. These involve four basic
variables:

• When neither the chimney connector nor the wall
has a heat shield installed.

• When only the chimney connector has a heat
shield installed.

• When only the wall has a heat shield mounted on
it.

• When a heat shield is installed on both the chim­ney connector and wall.

In general, the greatest clearance is required when the
stove will be positioned with no heat shield near a wall
with no heat shield. The least clearance is required
when both the stove and the wall have heat shields.
Reducing a stove clearance may require installation of
a listed heat shield on the chimney connector as well.

Clearances may be reduced only by means approved
by the regulatory authority, or in accordance with the
clearances listed in this manual.
