Floor Protection Requirements

A non-combustible floor protector (hearth extension) must be installed under the unit.
Check with local building authorities as to what other materials are acceptable.

The floor protector must extend:

1. Beyond the front door, a minimum of 16 inches (400 mm) in USA and 18 inches (450 mm) in Canada. See
measurement “B” on the floor protection drawing below.

2. On both sides of the unit, a minimum of 5 inches (125 mm) in USA and 8 inches (200 mm) in Canada. See
measurement “C” below.

3. On the back of the unit, a minimum of 0” (0 mm) in USA and 8 inches (200 mm) in Canada. See
measurement “A” below.

Notice: In case of installation with horizontal pipe, the floor protection must be extended beyond the back of the
appliance under the chimney connector and 2” (50 mm) beyond each side of the chimney connector.

Minimum requirements for floor protection on combustible floors

Types of Chimneys

The Chimney is a vital part of your stove installation. Your stove must be connected to either a code-approved
masonry chimney (a flue liner may be required), or a 6-inch diameter factory built chimney complying with the UL
requirements for Type HT chimneys (regulation UL 103 and ULC S629).

All chimneys must be installed either according to the local building codes in the case of a masonry chimney or
according to the chimney manufacturer’s instructions in the case of a factory-built metal chimney. See the chimney
manufacturers instructions for exact specifications. An oversized chimney may result in less than optimum
performance. Installations into a large, masonry chimney may require a liner to improve performance.

Chimney Inspection

Existing chimneys must be inspected before installing your stove. Consult your local building department for chimney
code requirements. A masonry chimney should have a code-approved liner. This liner must not have broken or
missing pieces. Some non-code masonry chimneys may be brought up to code by being relined. (Consult your dealer
or qualified chimney sweep.) Factory built metal chimneys should also be inspected, first for creosote deposits (which
would be removed), and then for integrity of the stainless steel liner. Look for obvious bulges in the lining, which may
indicate the need to replace that section (use a bright flashlight). Also inspect the attic to see that the chimney has
proper clearance to combustible framing members.

Draft Requirements

The appliance is merely one component of larger system. The other equally important component
is the venting system. This is necessary for achieving the required flow of combustion air to the
fire chamber and for safely removing unwanted combustion by-products from the appliance. If the
venting system’s design does not promote these ends, the system may not function properly. Poorly
functioning venting systems may create performance problems, as well as be a safety hazard
(i.e. an oversized chimney may result in less than optimum performance. Installations into a large
masonry chimney may require a liner to improve performance).

THE RECOMMENDED DRAFT REQUIREMENTS FOR YOUR STOVE IS NO LESS THAN -.04
AND NO GREATER THAN -.08. OPERATION OF YOUR STOVE WITH A DRAFT GREATER
THAN -.08 CAN POSSIBLY CAUSE DAMAGE TO THE STOVE AND VOID THE WARRANTY.

SPECIAL NOTE: A barometric damper is recommended for installations of stoves in areas that
may have high winds, which can affect the draft. The installation must be only in units with a newly
constructed chimney, free of creosote deposits. The barometric damper is an automatic device
designed to regulate the draft in a heating appliance, which in turn, stabilizes the chimney temperatures,
lessening the potential of over-firing. Do not place the barometric damper greater than 24 inches (610 mm) above the
unit. Excessive draft will lead to poor control of the burn rate, possible over-firing of the stove and damage to the cast
iron components of the firebox. Most barometric dampers are calibrated in inches of water column and can be set to
draft requirements of -.03 to -.08 inches (-7.5 to -20 Pa). It is recommended that the barometric dampers to be set
between -.05 and -.06 inches.

Chimney Height requirements

According to the American National Standards Institute ANSI/NFPA 211-92, draft 1-7, a chimney or vent shall be so
designed and constructed to develop a flow sufficient to completely remove all flue and vent gases to the outside
atmosphere. The venting system shall satisfy the draft requirements of the connected appliance in accordance with
the manufactures instructions.
The “3-foot, 2-foot, 10-foot rule” on chimney height states that a chimney must be:

1. At least 3 feet higher than the highest part of the roof opening through which it passes,

2. and at least 2 feet higher than any part of the roof within 10 feet, measured horizontally.

Due to prevailing winds, local terrain, adjacent tall trees, a hill or ravine near the home, or adjacent structures,
additional chimney height or a special chimney cap may be required to assure optimum performance.

Standard Installation Procedure

1. Position the unit no closer than the minimum clearances to combustible materials. Check that no overhead
cross members in the ceiling or roof will be cut. Reposition unit if necessary, being careful not to move closer
than the minimum clearances.

2. Mark the position of the required floor protector on the floor. Remove the unit and install the floor protector.

3. Position the unit on the floor protector at the proper clearances.

4. Install a 6-inch diameter, minimum 24 MSG black or 26 MSG blued steel connector pipe on the flue collar of
the unit.

5. The stove is NOT to be connected to any air distribution duct or system. A chimney connector shall not
pass through an attic or roof space, closet or similar concealed space, or a floor, or ceiling. Where passage
through a wall or partition of combustible construction is desired, the installation shall conform to CAN/CSA­ B365, Installation Code for Solid-Fuel-Burning Appliances and Equipment. (Canadian installations only).

6. Use a 6” chimney connector adapter to connect the chimney connector up to the chimney. The small ends of
the chimney connector should all point down to ensure a drip-free installation.

7. Check that all clearances are still within the allowable tolerances.

8. Secure adjoining sections of chimney connector to each other using three equally spaced sheet metal screws.
Secure the connector pipe to flue collar using three equally spaced sheet metal screws. DO NOT secure
chimney connector to chimney with screws.

9. The unit must be connected to either:

• a code-approved masonry chimney with a flue liner, or

• a 6 inch diameter factory built chimney complying with the requirements for Type HT chimneys in the
standard UL 103 and ULC S629.

WARNING:
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
UNIT MUST BE INSTALLED ACCORDING TO ALL LOCAL CODES. A BUILDING PERMIT MUST BE OBTAINED
BEFORE INSTALLING.
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
DO NOT INSTALL IN A MOBILE HOME.
READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING THE INSTALLATION.
UNIT MUST BE PROPERLY INSTALLED OR LISTING WILL BE VOID.
INSTALLATIONS OTHER THAN THOSE SPECIFICALLY COVERED HEREIN HAVE NOT BEEN CONFIRMED BY
TEST AND ARE NOT COVERED BY THE LISTING.

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 “breach”) must be lined with either a ceramic or metal cylinder,
called a “thimble”, which is securely cemented in place.

Fig. A: Chimney connection in a freestanding installation

8

Most chimney breeches incorporate thimbles, but the fit must
be snug and the joint between the thimble and the wall must be
cemented firmly (Fig. A)

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 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. Do not extend it into the actual flue
passage, as it could interfere with the draft.
The thimble sleeve should protrude 1-2” (25-50 mm) into the
room. User fire 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.

Above a Fireplace

In this type of installation, the chimney connector rises
from the stove, turns 90°, and then goes into the fireplace
chimney (Fig. B) 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:

• Double check the connector clearance from the
ceiling: 18” minimum.

• The fireplace damper must be closed and sealed
to prevent room air from being drawn up the flue,
thereby reducing the draft. However, it must
be possible to re-open the damper in order to
inspect the chimney.

Wall Pass-Through

Whenever possible, design your installation so that the wall 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 pass-throughs. If using one of these, make sure it has been tested and listed for use as a wall pass-through.

Chimney connector enters chimney above the

Wall Stud

The National Fire Protection Association (NFPA) has
established guidelines for passing chimney connectors
through combustible walls. Many building code
inspectors follow these guidelines when approving
installations.

The methods approved by the NFPA are:

• Cutting away all combustible material in the
wall a sufficient distance from the single wall connector,
to provide the required 12” (300 mm) clearance for the
connector. Any material used to close the opening must
be non-combustible (as in Fig . C).

• Using a section of double-wall chimney with a
9” (230 mm) clearance to combustibles.

• Placing a chimney connector pipe inside
a ventilated thimble, which is then separated from
combustibles by 6” (150 mm) of fibreglass insulating
material.

• 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 the combustibles.

Acceptable Types of Connector Pipe

Minimum Flue Diameter: Minimum 6”, Maximum 10”
Minimum recommended chimney height (from appliance to termination): 12’-15’

- When Using Single Wall Pipe: Install a 6-inch diameter, single wall, 24 MSG black steel or 26 MSG blued steel
connector pipe on the flue collar of the unit. The crimped ends of the pipeshould all point down. Additional sections of
single wall pipe should be fastened together with at least three sheet metal screws each section. All pipe connections
must be sealed (using high temperature silicone).

- When connecting to the factory-built ceiling support package, use the manufacturer’s transition piece, usually called
a dripless connector, to join single wall pipe to their factory-built chimney section.

- When using approved double wall pipe: Type L and listed doublewall connector pipe is acceptable. Install any
factory-built brand of pipe according to the manufacturer’s instructions. All pipe connections must be sealed.

- Chimney Connector Adapter - Use a 6-inch chimney connector adapter to connect the chimney connector up to the
chimney. The small ends of the chimney connector should all point down for a drip free installation. Secure adjoining
sections of chimney connector to each other using three sheet metal screws. Secure the connector pipe to flue collar
using three sheet metal screws. DO NOT secure chimney connector to chimney with screws.

- Connection to a factory built chimney - Your stove may be connected to a factory-built chimney conforming
to CAN / ULC – S629, Standard for 650°C Factory-Built Chimneys. All pipe connections must be sealed.

- For Reduced Residential Clearances Using Double Wall Pipe: Type L and listed double wall connector pipe is
acceptable. Install any factory-built brand of pipe according to the manufacturer’s instructions.
