PLANNING YOUR INSTALLATION
QUESTIONS TO ASK LOCAL BUILDING OFFICIAL
A correct installation is critical and imperative for reducing fire hazards and perilous conditions that can arise
when wood burning appliances are improperly installed.
The installer must follow all of the manufacturers’ instructions.
The installation of a wood burning appliance must conform to local codes and applicable state and federal
requirements. Familiarity with these requirements before installation is essential. Important considerations to
discuss with local building officials include:
1. Applicable codes (i.e. Uniform Mechanical Code,
State or Regional Codes)
Electrical codes: Optional Blower Assemblies have
a flexible electrical cord that must be electrically
grounded per local codes or per electrical codes:
In USA, NEC, ANSI/NFPA 70-1987
In Canada, CSA C22.1
WARNING: ELECTRICAL GROUNDING INSTRUCTIONS: THIS APPLIANCE IS EQUIPPED WITH A
THREE-PRONG (GROUNDING) PLUG FOR YOUR
PROTECTION AGAINST SHOCK HAZARD AND
SHOULD BE PLUGGED DIRECTLY INTO A PROPERLY GROUNDED THREE-PRONG RECEPTACLE.
DO NOT CUT OR REMOVE THE GROUNDING
PRONG FROM THIS PLUG. DO NOT ROUTE
POWER CORD UNDER OR IN FRONT OF APPLIANCE.
2. Local amendments?
3. Is a permit required - cost? (You may wish to contact your insurance company to ask if they require
this)
4. Is outside combustion air required?
5. Rooms where the installation is not allowed?
SMOKE DETECTORS
Since there are always several potential sources of fire
in any home, we recommend installing smoke detectors. If possible, install the smoke detector in a hallway
adjacent to the room (to reduce the possibility of occasional false activation from the heat produced by the
stove). If your local code requires a smoke detector be
installed within the same room, you must follow the requirements of your local code. Check with your local
building department for requirements in your area.

PLANNING YOUR INSTALLATION
A
FLOOR PROTECTION
This appliance requires non-combustible floor protector for
ember protection. If the floor protection is to be stone, tile,
brick, etc., it must be mortared or grouted to form a continuous
non-combustible surface. If a chimney connector extends
horizontally over the floor, protection must cover the floor under the connector and at least 2" (51 mm) to either side.
The floor protection must extend completely beneath the
stove and to the front, sides, and rear as indicated:
USA REQUIREMENTS:
16" to the front of the fuel door glass
4½" beyond the sides of the pedestal base
0" to the back of the stove body
CANADA REQUIREMENTS:
18" (457 mm) to the front of the fuel door glass

SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A
wood stove depends primarily on air circulation (convection) to disperse its heat, and therefore, a central
location is often best. There are other practical considerations, which must be considered before a final selection of locations is made.
♦ Existing Chimneys
♦ Wood Storage
♦ Aesthetic Considerations
♦ Roof Design (Rafter Locations & Roof Pitch)
♦ Room Traffic
♦ Proximity to Combustibles
♦ Electrical Wiring
The installation of this stove will require some research.
Once your options are determined, consult with your
local building department who will be able to give you
the necessary installation requirements for your area (Is
a building permit required, Rooms where installation
may not be allowed, etc.).
WARNING: CHECK ALL LOCAL BUILDING AND
SAFETY CODES BEFORE INSTALLATION. THE INSTALLATION INSTRUCTIONS AND APPROPRIATE
CODE REQUIREMENTS MUST BE FOLLOWED EXACTLY AND WITHOUT COMPROMISE. ALTERATIONS TO THE STOVE ARE NOT ALLOWED. DO
NOT CONNECT THE STOVE TO A CHIMNEY SYSTEM SERVING ANOTHER STOVE, APPLIANCE, OR
ANY AIR DISTRIBUTION DUCT. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL VOID THE
MANUFACTURERS WARRANTY.
If you plan to vent your stove into an existing masonry
chimney, have it inspected by a local fire marshal or
qualified installer. Remember that a stove's performance is heavily influenced by the chimney and its location on the roof. An oversized flue may not provide effective draw, and a flue liner may be required (see Draft
Requirements on page 10). Consult your dealer or
qualified installer before final selection is made.
This stove requires pre-installation work to be completed before installation can take place. This will include the preparation of the floor and appropriate
hearth pad for acceptance of outside air (if applicable),
and for modification for flue and chimney.

PLANNING YOUR INSTALLATION
COMBUSTIBLE WALL CLEARANCE
WARNING: IT IS VERY IMPORTANT THAT YOU
OBSERVE THE MINIMUM CLEARANCES.
There are listed clearances for your stove which were
determined in a Laboratory test using various "classes"
of stove pipe or chimney. Minimums are first established for the stove itself and increased based on how
much heat is transferred by each class of pipe.
Note: Manufactured (mobile) home installations require
the use of a Type L Vent Chimney connector only. Use
of a single wall flue pipe connection is not permitted.

INSTALLATION
MANUFACTURED (MOBILE) HOME REQUIREMENTS
Approved for USA only. This appliance is not approved for
installation into a manufactured home in Canada.
This stove is certified as a Room Heater, Solid Fuel Type
and may be used in Manufactured Housing providing the
following requirements are followed:
• WARNING: DO NOT INSTALL IN SLEEPING
ROOM.
• An outside air inlet must be provided for combustion
and be unrestricted while unit is in use.
• Regulations require that the appliance must be secured to the floor and grounded to the chassis. See
Securing the Stove to the Floor (and) Grounding
Stove, following.
• CAUTION: THE STRUCTURAL INTEGRITY OF
THE MOBILE HOME FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED.
VENTILATION REQUIREMENTS
THE FRESH AIR REQUIREMENTS OF THIS APPLIANCE MUST BE MET WITHIN THE SPACE WHERE IT
WILL BE INSTALLED.
Ventilation is essential when using a solid fuel burning
heater. The combustion process of this heater uses oxygen from inside the dwelling and it may be necessary to
open a window or to duct outside combustion air directly
to the appliance (as outlined in this manual). Modern
construction standards have resulted in homes that are
highly energy-efficient and that allow little heat loss and
air transfer. Other appliances in the dwelling also contribute to removing air from the dwelling (i.e. clothes dryers, exhaust fans, fireplaces, and other fuel burning appliances). If the available fresh air delivery in the dwelling
is insufficient to support the demands of these appliances, problems can result (i.e. excessive negative
pressure can develop in the dwelling which will affect the
rate at which this appliance can draft [See Draft Re-
quirements, page 10], icing can develop in some environments, etc.).
OUTSIDE COMBUSTION AIR
The following 2 optional kits are required to deliver outside air to this appliance. Contact your dealer to order.
Catalog # 14M67 Outside Air Floor Duct
Catalog # 14M68 Back Cover Plate
In all manufactured (mobile) homes and in many site built
residences (subject to local code), a stove may be required
to use outside air for combustion. A 5 ¼” square” outside
air floor duct Back Cover Plate is available through your
dealer.
This stove can take in outside air directly through the base.
This type installation requires a hole through the floor protector and the use of outside air floor duct to penetrate into the
air space below the home.
NOTES: The floor air duct can be positioned anywhere
2" in from either side under the pedestal. The floor air
duct opening must be protected from any possible obstruction including loose floor insulation. This part can be
purchased from your local dealer.
SECURING THE STOVE TO FLOOR
Manufactured (Mobile) Homes Only
Once the floor air duct and hearth pad are in position
confirm that the hole of the hearth pad is aligned with the
outside air opening. Next position and align the stove on
the hearth pad. Manufactured Home installations require
that the stove be secured to the floor. This ensures that
the stove will not shift if the Manufactured Home is ever
moved. To do this, drill two holes (use a marking instrument long enough and small enough to fit through the (4)
four holes in the pedestal base and mark the hearth pad.
Then remove the stove. Drill the (4) four holes, (2) two
on each side of the pedestal base) with a 1/4" drill bit.
Drill down through the hearth pad and the Manufactured
Home floor. Use 1/4" lag bolts and secure to the Manufactured Home floor.
NOTE: If the composition of the manufactured home
floor is of light particleboard construction, you will
be required to secure the stove with regular hex
head bolts and nuts. This will ensure that the bolts
will not rip out of the floor when the manufactured
home is being moved.
PAGE 7
INSTALLATION
GROUNDING STOVE
Manufactured (Mobile) Homes Only
Regulations require that all stoves installed in Manufactured Homes must be grounded. To do this simply attach a piece of No. 8 copper wire, at least 18" in length
from the stove to the chassis of the Manufactured
Home.
INSTALLING MARBLE ACCENTS
Marble is a natural product and therefore each piece
will have its own unique character. Marble can be
scratched so care should be taken to avoid putting
heavy or rough objects (trivet/steamers) on the surface.
If the marble should become scratched, the scratch
may be removed or diminished by polishing it with jewelers rouge (which can be purchased at many hardware
stores). Do not install the marble before curing the
paint.
The marble set consists of 2 pieces. A large piece
which fits onto the stove top and a smaller piece which
fits onto the ashlip (located below the fuel door).
Installation Steps:
Install the cerawool blanket, gasket strips and marble
set as follows:
1. Place the cerawool blanket and gasket strips onto
the stove top as shown in the following illustration.
REMOVE ASH DRAWER CLIP
The ash drawer is secured for shipping with a small
retaining screw at the top of drawer. Remove and discard this screw.
BAFFLE PLATES
This appliance has two heavy steel baffle plates that
are installed in the upper firebox (over the steel secondary air supply tubes). During shipment and installation, the baffle plates might slide around, and may need
to be repositioned (lined up to each other) and pushed
to the back wall in order for the stove to operate properly. When in the proper position, the rear edges of the
baffle plates should be flush to the back wall of the firebox. See Removing Baffle Plates for Cleaning on page
17 for additional information on installing baffle plates.
TYPES OF CHIMNEYS
The chimney is a vital part of your stove installation. A
properly built masonry chimney or a properly installed
factory built chimney will assure a consistent draft under
a variety of weather conditions (a smoking stove is usually caused by a chimney problem). The stove flue size
is 6 inches diameter, which is approximately 28 square
inches minimum. The maximum flue size should be no
more than (3)-three times the cross sectional area of
the size of the stove flue collar. In this case, that would
be no larger than a 10-inch diameter stack, or approximately 85 square inches maximum.
All chimneys must be installed as specified by local
building codes and according to the chimney manufacturer instructions (in the case of a factory built chimney).
See the chimney manufacturer instructions for exact
specifications. Factory built chimneys must comply with
UL 103HT or ULC S629.
2. Place the larger marble piece on top of the cerawool blanket and strips.
3. Place the smaller marble piece into recessed area
on the stove ashlip (located below the fuel door).
The ashlip marble requires no insulation.
PAGE 8
INSTALLATION
ACCEPTABLE CONNECTOR PIPE FOR INSTALLATIONS
For Standard Residential Clearances:
minimum, single wall, minimum MSG black or 25 MSG
blued steel connector pipe with listed factory-built chimney suitable for use with solid fuels or masonry. Three
(3) pre-drilled holes are provided in the flue collar for
fastening the pipe securely to the stove. Use sheet
metal screws to do this. Additional sections of single
wall pipe should be fastened together with at least three
(3) sheet metal screws each section. 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.
Minimum Flue Size
and area required for the flue size is (respectively) 6
inches / 152 mm diameter, which is approximately 28
square inches / 711 square mm. The maximum flue
size should be no more than (3) three times the cross
sectional area of the size of the 6 inches / 152 mm diameter flue collar. In this case, that would be no larger
than a 10 inch (254 mm) diameter (area = approx. 85
sq. inches [216 sq. cm]).
Connection To A Factory Built Chimney
heater is to be connected to a factory-built chimney
conforming to CAN / ULC – S629, Standard for 650°C
Factory-Built Chimneys.
For Reduced Residential Clearances:
listed double wall connector pipe is acceptable. Install
any factory built brand of pipe according to the manufacturer's instructions.
- The required minimum diameter
Six (6) inch
- This space
Type L and
Vapor Barrier at Chimney Penetration
Install all venting components per the Vent Manufacturers installation instructions. Ensure that there is an effective vapor barrier at the location where the chimney
penetrates to the exterior of the structure. This can be
accomplished by applying a non-hardening waterproof
sealant to the following components:
• Around the chimney at the point where the storm
collar will meet the chimney just above the Flashing.
• Along the vertical seam of the chimney pipe, where
it is exposed to the weather.
• On each nail head on the flashing.
• Around the chimney at the point where the storm
collar will meet the chimney just above the flashing.
Notes:
• On a flat or tarred and graveled roofs, nail and seal
the flat roof flashing to the roof on all sides with
roofing compound.
• Do not put screws through the flashing into the
chimney pipe.
CHIMNEY INSPECTION
Existing chimneys must be inspected before installing
your stove. Consult your local building department for
chimney code requirements. A masonry chimney must
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 chimneys should also be inspected, first for
creosote deposits (which should 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. For
interior masonry chimneys and most factory built chimneys, this must be a (2) two inch air space clearance,
which must not be filled with insulation or any other material. An exterior masonry chimney must have a (1)
one-inch air space clearance.
