CAUTION
After reading these instructions, if you have any doubt
about your ability to complete your installation in a
professional like manner you should obtain the services
of an installer versed in all aspects as to the correct
and safe installation. Do not use temporary makeshift
compromises during installation.
BEFORE INSTALLATION OF YOUR APPLIANCE
1. Check with the building inspector’s office for
compliance with local codes; a permit may be required.
2. The room heater must be connected to 1) a chimney
complying with the requirements for Type HT chimneys
in the standard for Chimneys, Factory-Built, Residential
Type and Building Heating Appliance, UL 103, or in
Canada CAN/ULC-S629 Standard for 650 degree C
Factory Built Chimneys and applicable building codes or
2) a code-approved masonry chimney with a flue liner.
3. A 6” (152mm) diameter, 24 gauge Black Steel flue is
required for proper performance.
4. Always connect this unit to a chimney and NEVER
vent to another room or inside a building.
5. DO NOT connect this unit to any duct work to which
another appliance is connected such as a furnace.
6. DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
7. The connector pipe and chimney should be inspected
periodically and cleaned if necessary.
8. Remember the clearance distances when you place
furniture or other objects within the area. DO NOT store
wood, flammable liquids or other combustible materials
too close to the unit.
Refer to certification label on back of your unit for
required clearances.
9. Contact your local municipal or provincial fire
authority for information on how to handle a chimney
fire. Have a clearly understood plan to handle a chimney
fire. In the event of a Chimney fire, turn air control to
closed position and CALL THE FIRE DEPARTMENT.
10. DO NOT tamper with combustion air control beyond
normal adjustment.
11. DO NOT CONNECT TO ANY AIR DISTRIBUTION
DUCT OR SYSTEM.
12. When installing a solid fuel appliance, it is also
recommended to install Smoke and Carbon Monoxide
Detectors on every level of the house. During the initial
firing of the appliance, some smoke or odor may occur
due to paint curing. You may want to keep some
windows open for ventilation during the first few hours of
burning to prevent smoke detector activation. Test your
smoke and carbon monoxide detectors regularly.
CAUTION
DO NOT operate heater if glass window is broken.
OPERATION
WHY THE CORRECT FLUE SIZE IS IMPORTANT - 6”
Draft is the force which moves air from the appliance up
through the chimney. The amount of draft in your chimney
depends on the length of the chimney, local geography,
nearby obstructions, and other factors. Too much draft
may cause excessive temperatures in the appliance.
An uncontrolled burn or a glowing red part or chimney
connector indicates excessive draft. Inadequate draft may
cause back puffing into the room and “plugging” of the
chimney and/or cause the appliance to leak smoke into the
room through appliance and chimney connector joints.
Today’s solid fuel appliances are more efficient than in
the past. The units are designed to give you controlled
combustion, and maximum heat transfer, using less fuel to
do so.
The design of your new appliance is such that the exhaust
smoke is now at lower temperatures than in the past,
therefore requiring proper chimney size to give adequate
draft. If your chimney is too large, the heating appliance
will have a difficult time to raise the chimney flue
temperature to give adequate draft, therefore causing a
smoke back up, poor burn, or both.
Should you experience such a problem call in a local
chimney expert.
With the door closed, the rate of burning is regulated by
the amount of air allowed to enter the unit through the
air control. With experience you will be able to set the
control for heat and burning time desired.
Once the required chimney draft is obtained, operate only
with doors closed and open doors slowly when re-fueling.
(This will reduce or eliminate smoke from entering the
room).
Attempts to achieve higher output rates that exceed
heater design specifications can result in permanent
damage to the heater. The recommended wood load is
level with the top of the firebricks.
Overloading may prevent sufficient air entering the heater
to properly fuel the fire.
Operate this heater only with the door closed.
DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS,
SUCH AS GASOLINE, NAPHTHA, OR ENGINE OIL
DO NOT USE CHEMICALS OR FLUIDS TO START
THE FIRE.
IMPORTANT: It is highly recommended that the wood
stove and chimney be installed by a qualified installer.
(A qualified installer is a person or entity who regularly
installs wood heating products and chimneys, in the
ordinary course of their regular business.)
This wood heater has a manufacturer-set minimum low
burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this
wood heater in a manner inconsistent with operating
instructions in this manual.
HOT WHILE IN OPERATION. KEEP CHILDREN,
CLOTHING AND FURNITURE AWAY. CONTACT
MAY CAUSE SKIN BURNS.
ALWAYS PROVIDE A SOURCE OF FRESH AIR
INTO THE ROOM WHERE THE UNIT IS INSTALLED.
FAILURE TO DO SO MAY RESULT IN AIR STARVATION
OF OTHER FUEL BURNING APPLIANCES AND
THE POSSIBLE DEVELOPMENT OF HAZARDOUS
CONDITIONS.

OUTSIDE AIR KIT INSTALLATION
A source of air (oxygen) is necessary in order for com-
bustion to take place. Whatever combustion air is con-
sumed by the fire must be replaced. Air is replaced via
air leakage around windows and under doors. In homes
that have tightly sealed doors and windows, an outside
air source is needed.

INSTALLATION
1. Remove all parts from inside the stove body.
2. Select the proper location for the stove. These
appliances must not be installed any closer than the
minimum clearance to combustible materials shown
in Brick pattern (Figure 1). The stove must be installed
on a non combustible surface as shown in Figure 1.
3. If noncombustible materials have been installed on
the walls, obtain the minimum clearances from either
the manufacturer of these materials or the local
building inspectors office.
4. Install the stovepipe INSIDE the flue collar on the top
of the stove between the stove and chimney.
5. DO NOT use a grate to elevate the fire.
STOVE PIPE
1. A clearance of 18 inches (457mm) between the
stovepipe and combustible materials may be required.
Check with authorities having jurisdiction in your area.
2. All pipe sections must be connected with the male end
(crimped end) toward the stove.
3. Fasten the stove pipe to the flue collar by the use of
three sheet metal screws. Do the same at each
additional joint to make the entire installation rigid.
4. Maintain the required diameter flue for the entire
installation.
5. If you are connecting the stove to an old masonry flue,
be sure to have it inspected for cracks and general
condition. Resizing with a stainless steel liner may be
required.
6. It is recommended that no more than two (2) 90°
bends be used in the stove pipe installation. More
than two (2) 90° bends may decrease the amount
of draw and possibly cause smoke spillage.
7. A damper is not required in this installation. Remove
damper plate in the chimney or secure in OPEN position.
8. Single wall flue pipe assemblies must not exceed
10 feet (3 m) in overall length.

require floor protection. If carpeting or any other com-
bustible floor covering is installed, a clearance around
the stove must be maintained equivalent to the size of
the floor protector described in the following section.
INSTALLATION ON A COMBUSTIBLE FLOOR
If the appliance is to be installed on a combustible floor
or floor covering, a floor protector must be inserted
under the stove and project beyond the front of the stove
a minimum of 16” (406mm) in the US or 18” (457mm) in
Canada and 8”(203mm) on all other sides. In the US
the floor protector must also be positioned under any
horizontal chimney run and project beyond the pipe a
minimum of 2” (51mm) on both sides. The floor protector
must be a durable noncombustible material with an “R”
value of 0 (no thermal protection required).
CHIMNEY
Where passing through a wall or partition of
combustible construction is desired, the installation
shall conform to CAN/CSA-B365.
CONTACT YOUR LOCAL BUILDING AUTHORITY
FOR APPROVED METHODS OF INSTALLATION
1. This appliance requires a masonry or pre-manufactured
chimney listed to CAN/ULC-S629 (Canada) and
UL103HT (USA) sized correctly.
2. If a masonry chimney is used it is advisable to have
your chimney inspected for cracks and check the
general condition before you install your unit.
Relining may be required to reduce flue diameter to
the appropriate functional size.
3. To help ensure a good draft, the top of the chimney
should be at least 3 feet (914mm) above the point of
penetration through the roof, and be at least 2
(610mm) feet higher than any point of the roof within
10 feet (3M).
4. The chimney connector shall not pass through an
attic, roof space, closet, concealed space, floor,
ceiling, wall, or any partition of combustible construction.
5. The minimum overall height of your chimney should be
15 feet (5 m) from the floor (Figure 3).
6. Do not use makeshift compromises during installation.
REFER TO CHIMNEY MANUFACTURER’S
INSTRUCTIONS
FLUE DRAFT CONSIDERATIONS
Location of the appliance and chimney will affect perfor-
mance. The chimney should:
• Penetrate the highest part of the roof. This minimizes
the affects of wind turbulence and down drafts.
• Consider the appliance location in order to avoid floor
and ceiling attic joists and rafters.
Exterior conditions such as roof line, surrounding trees,
prevailing winds and nearby hills can influence stove
performance. Your local dealer is the expert in your geo-
graphic area and can usually make suggestions or dis-
cover solutions that will easily correct your flue problem.
NOTE: These are guidelines only, and may vary some-
what for individual installations.
