PROPERTY DAMAGE, BODILY INJURY, OR EVEN DEATH. IF THIS APPLIANCE IS NOT PROPERLY INSTALLED,
A HOUSE FIRE MAY RESULT. CONTACT YOUR LOCAL BUILDING OR FIRE OFFICIALS ABOUT RESTRICTIONS
AND INSTALLATION INSPECTION REQUIREMENTS IN YOUR AREA.
1. If utilizing an older chimney, it must be inspected for adequate serviceability. Refer to
the heading Chimney Inspection on page 8 of
this manual.
2. The minimum clearances must be maintained
for all combustible surfaces and materials including; furniture, carpet, drapes, clothing,
wood, papers, etc. Do not store firewood
within this clearance space. Failure to maintain
clearances to all combustibles may result in a
house fire.
3. This appliance requires non-combustible floor
protection as outlined in this manual (see Floor
Protection on page 5 for additional information).
4. Minimum ceiling height must be 7 feet (213 cm)
(measured from base of appliance to ceiling).
5. DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE CONNECTED TO ANOTHER APPLIANCE.
6. Do not connect this appliance to air ducts or
any air distribution system.
7. PREVENT CREOSOTE FIRE: Inspect and clean
chimney frequently. Under certain conditions
of use, creosote buildup may occur rapidly. Inspect chimney connector and chimney twice
monthly and clean if necessary. Using green or
inadequately seasoned wood can greatly increase creosote buildup. Use dry wood to
minimize creosote buildup.
8. USE SOLID WOOD FUEL ONLY: This appliance
is approved for burning dry seasoned natural
wood only. CAUTION: BURN UNTREATED
WOOD ONLY. OTHER MATERIALS SUCH AS
WOOD PRESERVATIVES, METAL FOILS,
COAL, PLASTIC, GARBAGE, SULFUR OR OIL
MAY DAMAGE THE CATALYST. DO NOT BURN
GARBAGE OR FLAMMABLE FLUIDS SUCH AS
GASOLINE, NAPHTHA OR ENGINE OIL.
9. Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fluid, or similar liquids to start or "freshen up" a fire in this
heater. Keep all such liquids well away from the
heater while it is in use.
10. DO NOT OVERFIRE: If heater or chimney connector glows, you are overfiring. Overfiring this
appliance could cause a house fire. Overfiring
is a condition where the appliance is operated
at temperatures above its design capabilities.
Overfiring can be caused by improper installation, improper operation, lack of maintenance
or improper fuel usage. Damage caused from
overfiring is NOT covered under the manufacturers limited warranty.
11. NEVER LEAVE AN UNATTENDED STOVE
BURNING ON HIGH. Operation of the stove
with the primary air control at its highest burn
rate setting for extended periods can cause
dangerous overfiring conditions. The primary
air control should only be positioned at the
highest setting during start-up procedures and
for short durations. When leaving the stove
unattended ensure that the primary air control
is set to the low or medium low range.
12. Use a metal container with a tight fitting lid to
dispose of ashes.
13. IN THE EVENT OF A COMPONENT FAILURE,
USE ONLY COMPONENTS PROVIDED BY THE
MANUFACTURER AS REPLACEMENT PARTS.
14. Burning any kind of fuel uses oxygen from the

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 re-
quire this.)
4. 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 adja-
cent 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 de-
partment for requirements in your area.
NOTE – This appliance is NOT approved for installa-
tion into a Manufactured (Mobile) Home in Canada
or the US.

FLOOR PROTECTION
This appliance requires ½" (13 mm) minimum noncombustible floor protection designed for solid fuel burning appliances having a thermal conductivity of k = .84
BTU in/ft or equivalent. If the floor protection is to be
stone, tile, brick, etc., it must be mortared or grouted to
form a continuous non-combustible surface (See Using
Alternate Material As Floor Protector below). 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” min. to the front of the fuel door glass
8” min. beyond the sides of the fuel door opening
6” min. to the back of the stove body
CANADA REQUIREMENTS

USING ALTERNATE MATERIAL AS FLOOR PROTECTOR
The alternate material used as a floor protector must be
constructed of a durable noncombustible material having an
equal or better insulating value (lower k value) of k = .84
BTU / IN FT
exceeds r = 1.19 HR °F FT
2
HR °F or a thermal resistance that equals or
2
IN/BTU. With these values, determine the minimum thickness/material required using the
formula and the table shown here (see chart - Alternative
Floor Protection Materials).
Note: Any noncombustible material having a thickness of
1/2” (12.7 mm) whose k value is less than .84 or whose r
value is more than 1.19 is acceptable. If the alternate
material used has a higher k value or lower r value will
require a greater thickness of the material used. In some
cases, if the k value is less or the r value higher, a thinner
material may be used.
Methods of determining floor protection equivalents:
To determine the thickness required for any material
when either the k or r values are known:
T
= Thickness of material in inches
M
KM = K value of desired material
= Minimum listed thickness
T
L
rM = r value of desired material
Example: Micore CV230 is to be used for the floor protection. How thick must this material be?
The following formulas give the means of determining
minimum thickness required of alternate materials.
Using the k formula:
Desired Thickness k value of desire Minimum thickness
of the alternate = material (per inch) x of Listed
material k value of listed Material
TM (inches) = KM x T
T
(inches) = 0.43* x 1/2”
M
material (per inch)
.84
.84
L
Answer using k: 0.50 x 0.50” = 0.25 = 1/4”
1/4” thickness Micore will be required.
Using the r formula:
TM (inches) = 1.19 x T
r
M
L
TM (inches) = 1.19 x .5”
2.33*
Answer using r: 0.50 x 0.50” = .25 = 1/4”
3/8” thickness Micore will be required.
At times it is important to know what combination of materials are acceptable for use as floor protection. The “R
values” are used to determine acceptable combinations
of materials because “R values” are additive where r and
k values are not.
“R value” = 1 = r x thickness of material used

PLANNING YOUR INSTALLATION
SELECTING A LOCATION
The design of your home and where you place your
stove will determine its value as a source of heat. A
woodstove 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.).
COMBUSTIBLE WALL CLEARANCE
WARNING! IT IS VERY IMPORTANT THAT YOU OBSERVE THE MINIMUM CLEARANCES.
These are the listed clearances for this appliance which
were determined in laboratory tests. Minimums are first
established for the stove itself and increased or decreased based on how much heat is transferred by the
pipe.
USA and CANADA RESIDENTIAL ONLY (not approved
for manufactured (mobile) home) using single wall pipe
connector to the top of the stove.
A 16" / 406 mm D 11" / 279 mm
B 40" / 102 cm E 30" / 762 mm
C 30" / 762 mm F 20" / 508 mm
CORNER INSTALLATION
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, page 9). 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 may include modification for flue and chimney.
PARALLEL INSTALLATION

PLANNING YOUR INSTALLATION INSTALLATION
REDUCED MASONRY STRUCTURE CLEARANCE
(ALCOVE)
Your stove can be installed in a masonry structure with
reduced clearances if the structure was built to National
Building Code for fireplaces and chimneys (UBC 37).
The firebox of the masonry structure must be of adequate size to allow a minimum of 6" (152 mm) clearance
to the sides and top of the stove and 2" (51 mm) clearance to the rear. All stove models must be installed on
their original listed legs or base unless otherwise specified by OMNI Testing Laboratory.
The minimum venting requirement is a listed chimney
liner that extends from the flue collar of the stove to the
first tile liner of the chimney where it is sealed. All joints
and connections must be made airtight to prevent leaking
and
downdrafts.
PROTECTED WALL CLEARANCE
Some local codes will allow reduced clearances when the
stove is installed adjacent to a protected wall system.
Your local building official must approve the variance.
Normally, the protected wall system is defined as a noncombustible material with a minimum of 1" (25.4 mm) air
space behind. Check your local building codes or with a
qualified installer (Ref. NFPA 211).
INSTALLING (OPTIONAL) MARBLE ACCENTS
See Optional Accessories, page 25 for ordering information.
Important Note; Optional marble cannot be used if tem-
perature probe is used.
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 in-
stall the marble before curing the paint.
The marble set consists of 2 pieces. A large piece that
fits onto the stove top and a smaller piece that fits onto
the ashlip (located below the fuel door).
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 install a vent to provide make-up air
into a dwelling that is well insulated (modern construction
standards have resulted in homes that are highly energyefficient 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 Requirements, page 9], icing
can develop in some environments).
Installation Steps:
Install the ceramic fiber blanket, gasket strips and marble
set as follows:
Note: The fiber blanket and gasket strips are provided with the
stove: The marble sets are optional accessories.
1. Using scissors cut the ceramic fiber blanket so that it
fits into the recess of the stovetop.
2. Place the top marble piece onto the ceramic fiber
blanket.
3. Place the gasket strips into the recess of the ashlip
so that they are evenly spaced. This will slightly ele-
vate the marble so that it is not making direct surface
contact. Note: Insulation is not required in this area.
4. Place the ashlip marble onto gasket strips in ashlip
recess.

INSTALLATION
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 (I52 mm) diameter, which is approximately 28
square inches (711 square mm) 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 (254
mm) diameter stack, or approximately 85 square inches
216 square cm) 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.
Connection To A Factory Built Chimney: This space
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: Type L and
listed double wall connector pipe is acceptable. Install
any factory built brand of pipe according to the manufacturer's instructions.
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.
ACCEPTABLE CONNECTOR PIPE FOR INSTALLATIONS
For Standard Residential Clearances: Six 6 inch (152
mm) minimum, single wall, 25 gage minimum thickness,
stove pipe is acceptable. 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: The required minimum diameter
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]).
Notes:
• On 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 chim-
ney 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 (51 mm) air space clearance, which must not
be filled with insulation or any other material. An exterior
masonry chimney must have a (1) one-inch (25.4 mm) air
space clearance.
PAGE 8
INSTALLATION
CHIMNEY HEIGHT REQUIREMENTS
The chimney must extend 3 feet (914 mm) above the
level of roof penetration and a minimum of 2 feet (610
mm) higher than any roof surface within 10 feet (305 cm)
(see below). Check with your local building officials for
any additional requirements for your area.
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 ensure optimum performance.
Top of the flue must be 3’ (915
mm) higher than highest point
of roof penetration
Top of the flue must be
2’ (610 mm) higher than
any part of roof within
10’ (305 cm) horizontal
These rules are minimums. in some instances,
chimney height may need to be increased to
achieve sufficient draft.
To achieve a stable draft, the total flue height required
(from the appliance to termination) is 12 to 15 feet (366 to
457 cm) minimum.
DRAFT REQUIREMENTS
The appliance is merely one component of a 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 byproducts 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). A draft test should read
greater than .04' W.C. (inches water column) and less
than .08" W.C.
American National Standards Institute ANSI/NFPA 21192: 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 manufacturer instructions.
