Stove Safety
When properly maintained and operated your stove should give you many years of service. However there
are important safety aspects of these products that you need to be aware of when operating a wood stove.
1. Only use solid wood fuel. Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter
fluid, naphtha, engine oil, or similar liquids to start or „freshen up‟ a fire in this stove. Keep all such
liquids well away from the stove while it is in use. Do not burn garbage in the stove.
2. The burning of wood gives off gases which can be extremely dangerous. The stove is designed that
under normal operating circumstances these gases pass up the flue chimney system and cannot
escape into your home, however it is important that your flue system is properly installed and that
you check all joints regularly to ensure that there are no cracks or gaps, check the door sealing rope
and replace when damaged. We recommend a smoke alarm be fitted in rooms where stoves are
installed. Do not use stove in a room where negative pressure conditions may occur, such as
through the use of extraction fans unless an adequate air supply into the room is ensured, as this
may draw air through the stove and cause products of combustion to escape into the room.
3. Creosote and soot may accumulate in your flue pipe and chimney. This may ignite, causing a
chimney fire. If you suspect a chimney fire evacuate people from the building, close down the air
controls on the stove and call the Fire Department. To prevent the accumulation of soot or creosote,
check flue and chimney regularly and clean as necessary. Good burning, hot stoves will generally
cause a lot less build-up than slow burning stoves. Likewise dry wood will cause less build-up than
wet wood. We recommend a fire extinguisher be available where stoves are in operation. In the
event of a chimney fire do not re-light the stove until it and the flue chimney system have been
thoroughly checked and repaired as necessary.
4. Stoves get extremely hot and should not be touched when lit. When young children are in the area,
we recommend the use of a suitable fire guard around the stove. Always wear protective gloves
when reloading stove.
5. Never over-fire your stove. If external parts of your stove are glowing red then the stove is over-firing
and your draft settings should be reduced. Never interfere with the draft mechanisms or adjust your
air settings outside those limits set when the stove is manufactured. Never use a fan to supply air to
the stove or to extract air from it.
6. All users of the stove should be aware of the contents of this manual. Please leave this manual
where it is accessible to stove users and do not allow anyone to use the stove that is unfamiliar with
its correct operation.
7. Never use the stove if any parts are missing or damaged, only use genuine parts as replacements.
Never modify your stove.
8. Do not install in a mobile home.
We hope you have many years of warmth and comfort from
your stove but please do so safely.

Check Building Codes
When installing, operating and maintaining your stove, follow the guidelines presented in these
instructions, and make them available to anyone using or servicing the stove.
Your city, town, county or province may require a building permit to install a solid fuel burning appliance.
In the U.S., the National Fire Protection Association‟s Code, NFPA 211, Standards for Chimneys,
Fireplaces, Vents and Solid Fuel Burning Appliances, or similar regulations, may apply to the installation
of a solid fuel burning appliance in your area. In Canada, the guideline is established by the CSA
Standard, CAN/CSA-B365-M93, and Installation Code for Solid-Fuel-Burning Appliances and Equipment.
Always consult your local building inspector or authority having jurisdiction to determine what regulations
apply in your area.
Before installing your stove
You need to consider the following to ensure the safe operation of your stove.
• Provision of adequate air to support efficient combustion of the fuel.
• A well sealed flue/chimney system, herein after referred to as the “flue system”.
• The protection of combustible materials in proximity of the stove.
Adequate provision air
It is essential for the safe and efficient use of your stove that you provide an adequate air supply
to your stove. This may mean the provision of an outside air supply to the room, especially if
there are extraction units such as cooker hoods or clothes dryers in the vicinity. Failure to do so
will mean that fuel is burned inefficiently causing smoke and blackening the glass and may also
cause smoke to come back into the room. As a simple check for this open a door or window in
the room and check if the stove burns more efficiently.

5
Installation
Unpacking and preparing your stove for installation.
1. Remove your stove from the outer packaging and place on floor. Please inspect stove
and check that it is not damaged in any way. Never attempt to use a stove that has been
damaged.
2. If you are installing the stove yourself, proceed as follows. However, if you are unsure
about any aspect of stove installation, please contact your dealer and he will discuss
installation with you or put you in touch with an experienced stove installer.
3. Open fire door. Remove and check the following contents.
4 stove legs
Wooden handle and screws
Ash pan
Operating tool
Handle holder
In the unlikely event that something is missing please contact your dealer immediately and
we will rectify the situation.
4. Gently lay the stove on its back. Remove screws from 4 corners of base and fit one of the
legs to each corner of the stove. Tighten bolt to ensure leg is secure to base of stove.
When complete, gently stand the stove upright.

5. Remove hob and lay it upside down on soft surface, remove hob blanking plate from
underside of hob by taking out 2 screws, remove flue blanking plate from top outlet and fit
to back outlet making sure it is properly sealed with ceramic rope or approved fire
cement.
6. Move the stove into position. Do not drag the stove as this may damage the legs,
screws or base.
The floor protection
If the stove is to be installed on a combustible floor, it must be placed on a non-combustible
hearth pad. In the USA, the floor protector must extend 8” beyond each side of the flue loading
door and 16” to the front. In Canada, the floor protector must extend 8“ (200mm) beyond each
side and the back of the appliance and 18“ (450mm) to the front. (See fig. 4)
Fig. 4
In a rear vent installation the floor protection must also extend under the stovepipe a minimum
of 2” (50mm) beyond either side of the pipe.

Installation Clearances
It is extremely important that you respect required installation distances and that you respect
local installation regulations. This is for your safety! The manufacturer is not responsible for the
product, if it is not installed following these recommendations. These clearances may only be
reduced by means approved by the regulatory authority.
One necessary precautions when installing a wood stove is to leave sufficient space between
the stove (top, sides, back, front, and under stove pipes) and any other material that can catch
fire.
A combustible surface is anything that can burn (i.e. sheet rock, wall paper, wood, fabrics etc.)
These surfaces are not limited to those that are visible and also include materials that are
behind non-combustible materials. If you are not sure of the combustible nature of a material,
consult your local fire officials.

Well sealed flue system
Only materials and items approved for solid fuel stoves should be used for your stove. Under
no circumstances should you use aluminum or galvanized steel pipes for your stove flue.
Always fit pipes with the narrow side down, this allow any creosote to run down the inside of the
pipe and not to come out and cause an unsightly mess and possible fire hazard. All joints in the
flue system should be sealed with fire cement and/or an appropriate fire resistant rope or gasket.
Pipe bends should be kept to a minimum and we do not recommend using more than 2 bends
on any installation. Flues must not pass through ceilings, floors, attics, roofs, or combustible
walls without adequate and approved insulation being provided to protect combustible materials.
The chimney and flue provide a means of taking combusted fuel from the stove, as well as a
draft to enable the stove to work. It is essential that the flue system is kept in good condition and
there are no breaks or cracks allowing contact with any other combustible materials of the
house. It is also essential that the flue system is kept clean and seals are maintained to ensure
the draft is not lost.
The open end of the flue system must be above the height of the apex of the building and any
other obstructions, such as trees, which are within 3 meters (10ft) of the flue system. Failure to
do this will affect the efficiency of the stove and may cause down drafts which will mean
dangerous products of combustion are emitted into room.
Under no circumstances should the flue pipe be less than 6” (125mm) internal diameter.
Chimney connection
The chimney connector is a single walled pipe used to connect the stove to the chimney. For
use with the appliance the chimney connector MUST be 6” in diameter, with a minimum
thickness of 24 gauge black steel or 26 gauge blued steel.
Aluminum and galvanized steel pipe is not acceptable for use with the appliance. These
materials cannot withstand the extreme temperatures of a wood fire and can give off toxic fumes
when heated.
Do not use the connector pipe as a chimney.
Each chimney connector or stovepipe section must be installed to the stove flue collar and to
each other with the male (crimped) end toward the stove. See fig 5.
Fig. 5

9
This prevents any amount of condensed or liquid creosote from running down the outside of the
pipe or the stovetop. All joints, including the flue collar connection must be secured with three
sheet metal screws to ensure that the sections do not separate.
For the best performance the chimney connector should be as short and direct as possible, with
no more than two 90elbows. The maximum horizontal run is 36” and a recommended total
length of stovepipe should not exceed 10 feet. Always slope horizontal runs upward ¼” per foot
toward the chimney.
No part of the chimney connector may pass through an attic or roof space, closet or other
concealed space, or through a floor ceiling. All sections of the chimney connectors must be
accessible for cleaning. Where passage through a wall or partition of combustible construction
is desired, the installation must conform with NFPA 211 or CAN/CSA-B365, and is also
addressed in this manual.
Chimney
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER
APPLIANCE. DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.
This room heater must be connected to a 6” factory built UL 103 HT chimney (ULC
S629, in Canada) or a code-approved masonry chimney with a flue liner.
Chimney Height
A masonry chimney or a listed factory-build chimney must be the required height above the roof
and any other nearby obstructions. The chimney must be at least 3‟ (90 cm) higher than the
highest point where it passes through the roof and at least 2‟ (60 cm) higher than the highest
part of the roof or structure that is within 10‟ (305 cm) of the chimney, measured horizontally.

10
Factory Built Chimney
When a metal prefabricated chimney is used, the manufacturer‟s installation instructions must
be followed. You must also purchase (from the same manufacturer) and install the ceiling
support package or wall pass-through and “T” section package, firestops (where needed),
insulation shield, roof flashing, chimney cap, etc. Maintain proper clearance to the structure as
recommended by the manufacturer. The chimney must be the required height above the roof or
other obstructions for safety and proper draft operation.

11
Masonry Chimney
Ensure that a masonry chimney meets the minimum standards of the National Fire Protection
Association (NFPA) by having it inspected by a professional. Make sure there are no cracks,
loose mortar or other signs of deterioration and blockage. Have the chimney cleaned before the
stove is installed and operated. When connecting the stove through a combustible wall to a
masonry chimney, special methods are needed.

12
Combustible Wall Chimney Connector Pass-Throughs
Method A. 12” (304.8 mm) Clearance to Combustible Wall Member: Using a
minimum thickness 3.5” (89 mm) brick and a 5/8” (15.9 mm) minimum wall
thickness clay liner, construct a wall pass-through. The clay liner must
conform to ASTM C315 (Standard Specification for Clay Fire Linings) or its
equivalent. Keep a minimum of 12” (304.8 mm) of brick masonry between
the clay liner and wall combustibles. The clay liner shall run from the brick
masonry outer surface to the inner surface of the chimney flue liner but not
past the inner surface. Firmly grout or cement the clay liner in place to the
chimney flue liner.
Method B. 9” (228.6 mm) Clearance to Combustible Wall Member: Using a 6”
(152.4 mm) inside diameter, listed, factory-built Solid-Pak chimney section
with insulation of 1” (25.4 mm) or more, build a wall pass-through with a
minimum 9” (228.6 mm) air space between the outer wall of the chimney
length and wall combustibles. Use sheet metal supports fastened securely
to wall surfaces on all sides, to maintain the 9” (228.6 mm) air space. When
fastening supports to chimney length, do not penetrate the chimney liner (the
inside wall of the Solid-Pak chimney). The inner end of the Solid-Pak
chimney section shall be flush with the inside of the masonry chimney flue,
and sealed with a non-water soluble refractory cement. Use this cement to
also seal to the brick masonry penetration.
Method C. 6” (152.4 mm) Clearance to Combustible Wall Member: Starting
with a minimum 24 gage (.024” [.61 mm]) 6” (152.4 mm) metal chimney
connector, and a minimum 24 gage ventilated wall thimble which has two air
channels of 1” (25.4 mm) each, construct a wall pass-through. There shall
be a minimum 6” (152.4) mm separation area containing fiberglass
insulation, from the outer surface of the wall thimble to wall combustibles.
Support the wall thimble, and cover its opening with a 24-gage minimum
sheet metal support. Maintain the 6” (152.4 mm) space. There should also
be a support sized to fit and hold the metal chimney connector. See that the
supports are fastened securely to wall surfaces on all sides. Make sure
fasteners used to secure the metal chimney connector do not penetrate
chimney flue liner.
Method D. 2” (50.8 mm) Clearance to Combustible Wall Member: Start with
a solid-pak listed factory built chimney section at least 12” (304 mm) long,
with insulation of 1” (25.4 mm) or more, and an inside diameter of 8” (2
inches [51 mm] larger than the 6” [152.4 mm] chimney connector). Use this
as a pass-through for a minimum 24-gage single wall steel chimney
connector. Keep solid-pak section concentric with and spaced 1” (25.4 mm)
off the chimney connector by way of sheet metal support plates at both ends
of chimney section. Cover opening with and support chimney section on
both sides with 24 gage minimum sheet metal supports. See that the
supports are fastened securely to wall surfaces on all sides. Make sure
fasteners used to secure chimney flue line
NOTES:
1. Connectors to a masonry chimney, excepting method B, shall extend in one continuous section through the wall pass-through system and the
chimney wall, to but not past the inner flue liner face.
2. A chimney connector shall not pass through an attic or roof space, closet or similar concealed space, or a floor, or ceiling.

Operating Your Stove
Do not use a grate, andiron or other fuel support method. Build fire directly on the hearth.
Only open door to fuel/refuel the stove. Excess air can cause the stove to over fire. Do not
over fire, if chimney or stove is glowing red you are over firing.
Do not build the fire too close to the glass. Do not abuse the glass doors. Do not strike or
slam shut the door.
Fuel
Your stove is designed to burn solid wood fuel only; it is not designed to burn,
• Paper or cardboard, other than small amounts used to light stove.
• Treated or painted wood
• Synthetic fuel or logs that are not approved for solid fuel stoves
• Household rubbish
• Liquid fuels
• Plastics
Burning these or other products for which the stove was not designed may damage the
stove and cause a fire hazard or release toxic fumes
Fuel should be stored in a dry place; wood should be dried for at least 1 year. Do not store
fuel within the installation clearances or within the space required for charging and ash
removal. Wet wood may cause serious creosote, which may damage your flue system and
even your stove. Therefore the use of wet wood is strongly discouraged.
First operation of stove
You should begin using your stove by lighting small fires which get progressively bigger. We
recommend a series of about five small fires before you put the stove into full service. Allow
the stove to fully cool between each of these fires. There may be some smell and a small
amount of smoke from the stove during the initial operations. This is perfectly normal and is
merely the curing of the stove paint. Opening a window or door to provide additional
ventilation will help alleviate this.
Air controls
Your stove needs air to burn the fuel. This air is supplied through the spin valve at the base
of the door and through the slots over the glass.
Primary air, as the name suggests, is used for the initial burning of the fuel. Secondary air is
used for secondary combustion, which makes the stove more efficient, reduces the
emissions and is also used to keep the stove glass clean. Wood burns better with the air
over the fire bed and when burning a lot of wood, you should use the secondary air supply
more.
The settings of both of these air controls very much depends on draft and local conditions
and after a few fires, you should have a good idea of the best settings for your stove. The air
controls should be fully opened when lighting the fire. Once the fire is established, the
controls may be adjusted as required. Reducing the air intake will cause the stove to burn
slower. This may cause some blackening of the stove glass, but this should burn off once
the stove is burning brightly again.

14
Refueling
Before refueling your stove, turn the air supply to high for a few moments until there is a
good fire in the stove. This will ensure there is no build-up of harmful gases in the stove
when the door is opened and will also get the new fuel burning quickly and not allow it to kill
the fire.
To reload the stove, open the door and feed the fuel in slowly using tongs or a small shovel.
Do not overfill the stove. It is always better to put in small loads often rather than big fills less
frequently. Close the door gently after stove is reloaded.
You should always wear protective gloves and use tongs when tending a hot stove.
Ash removal
Your stove is fitted with a shaker grate to remove the ash from the firebox. Use the operating
tool to move the shaker knob forward and back. This will allow the ash to fall into the ash
pan under the fire bed. This can also be achieved by using a poker.
When ash has built up in the ash pan, it should be emptied. Failure to do this will cause ash
to build up around the grate and may cause your grate to warp or burn out. It is especially
important when burning fuel with high ash content that you keep your grate clear and your
ash pan emptied regularly, so as not to damage your grate. Clear the grate with the shaker
bar or a poker regularly.
To remove the ash, open the stove door and use the operating tool provided to lift the ash
pan out of the stove. If possible, this should be done before lighting the stove when the ash
is cold. Even if the ash appears to be cold, it should be placed in a non-combustible
container as there may be hot ash in the center of the pile. You should always were
protective gloves when removing ash from the stove.
This stove is not designed to operate with the door open. Always close the stove door when
you have taken out the ash tray and leave closed while disposing of the ash. Only reopen to
put ash pan back into the stove and close immediately afterwards.
Ashes should be placed in a metal container with a tight fitting lid. The closed container of
ashes should be placed on a noncombustible floor or on the ground, well away from all
combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be retained in the closed container until all cinders
have thoroughly cooled. Do not place any other waste in the container.
Overnight burning
Your stove is designed to allow overnight burning. To do this, put a good fuel bed into the
stove and allow it to burn for about 15 minutes so as not to kill the fire. Then close the
secondary air supply at the top of the door and turn the primary air inlet to almost closed.
The exact setting of this depends on local conditions, but we suggest you begin with about a
½ turn open. If the fire burns away, then next time close it a little more. If the fire goes out,
you need to try with it a little more open. After a couple of nights, you will find the setting that
best suits the local conditions of your stove.

15
When you return to your stove, fully open both air controls until you have a good fire and
then set to normal operating levels. Do not add fuel until the fire bed is hot and red. Then
add a little for the first time and allow that to ignite before adding more. During overnight
burning, the stove glass will blacken, but when a hot fire is established again this should
burn off.
Stove Maintenance
Check stove regularly
Creosote –Formation and Need for Removal –When wood is burned slowly, it produces tar
and other organic vapors, which combine with expelled moisture to form creosote. The
creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining. When ignited, this creosote makes
an extremely hot fire. The chimney and chimney connector should be inspected at least
once every two months during the heating season to determine if a creosote buildup has
occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney
fire.
Initially, we recommend you check your flue system at least once per month. After the first
few months you will notice a pattern of soot and creosote build up and you can then
determine an inspection interval for checking soot and creosote build up that is suitable for
your stove installation.
Other checks, as listed below, should be carried out at least twice per year. If you notice
anything wrong at any time it should be repaired immediately. Never use a stove that is in
any way damaged or has a damaged flue.
1. Check your flue system for build up of soot or creosote and for signs of damage to
joints. To check flue outlet remove top of baffle by lifting and pulling out at end. Use a
flashlight to check flue outlet. Clean and repair as necessary. Always replace top baffle
before relighting stove.
2. Check that glass is not cracked or chipped and that sealing rope is in good condition.
Replace as necessary.
3. When the room is dark, use a strong flashlight to check the sealing of the stove at the
edge and corners for leaks. Any leaks or cracks found should be repaired with fire
cement or damaged parts should be replaced with genuine spare parts.
4. Check that stove door is tight and well sealed when closed. Place a strip of paper into
the stove and close the door, try to pull out paper. You should feel some resistance to
your pull, check several points around the door. If it pulls out too easily, replace the rope
and seal in place with a suitable high temperature sealant.
Care of glass
At times, especially when the air controls are turned to low settings or when damp wood is
used, the stove glass will blacken. This is caused by fuel that is not completely burnt, but the
build-up on the inside of the glass will normally burn off when a good hot fire is established in
the stove.
There may be times however when you need to clean the glass. To do this, use a soft cloth
and a non-abrasive glass cleaner. Only ever clean the glass when the stove is cold. When
loading fuel into the stove, always make sure it is not protruding out through the door
opening, as this may break the glass when you close the door. This is especially relevant
when loading logs. Always close the door gently.

16
Do not operate with broken or cracked glass. If the glass does crack when the stove is lit, let
the fire die out. Do not open the door until the stove has fully cooled. Replace the glass only
with the specified replacement part before re-using the stove.
Replacement of glass
1 Remove the door from the stove and place on a flat surface.
2 Carefully remove all of the glass clips from the inside of the door.
3 Gently remove the glass panel and gasket.
4 Using a wire brush, remove all remaining debris from the glass area.
5 Apply a small bead of gasket/stove cement and the new gasket. Do not overlap the
ends of the gasket rope.
6 Center the new glass panel over the gasket and reinstall the glass clips.
7 It may be necessary to retighten the glass clips after the stove has be burned and the
gasket has been seated.
Important: 1. It is extremely important to tighten the glass clips slowly and in an
alternating pattern.
2. Always wear protective gloves when you handle glass with sharp edges.
Replacement parts
Always use genuine replacement parts, ask retailer for compatible replacement parts. Only
ever make replacements when the stove is cold.

Surface finish
The stove should only be cleaned using a damp cloth. Some cleaning products may leave
stains on the stove surface. Never use abrasive cloths as these may scratch the surface.
Painted stoves can be re-painted by using a good quality, high temperature stove paint.
When re-painting, make sure there is plenty of ventilation and follow the manufacturer‟s
instructions. Allow the paint to fully dry before lighting the stove and allow extra ventilation
for the first couple of fires as some fumes may emit from the stove as the paint cures.

18
Trouble Shooting
Fire not burning
A stove not burning is generally caused by either a shortage of air and/or incorrect or damp
fuel. If fuel is not the problem check:
That the air controls are opened.
There is no blockage in the flue system.
That the open end of the flue is above the height of any nearby obstructions.
That there is a sufficient air supply into the room and that this supply is not being
taken by an extractor fan.
Glass blackens
Glass usually blackens when:
The fuel is not being burned efficiently because of starvation of air.
Bad quality or damp fuel is being used.
Balance between primary and secondary air is incorrect.
Try to introduce more air into the stove, especially through the secondary air control on the
top of the stove door as this air flows down over the glass to help burn off the creosote. For
optimum efficiency always use a good quality wood.
Smoke in room
If the stove is properly installed it should not emit any smoke into your room. Should this
happen,
Check that your room is not air tight. This can easily be checked by opening a door or
window. If the smoking stops you need to provide an additional air supply into the room. If
this is not the problem, check if your chimney is blocked or obstructed and that you are not
getting a down draft caused by the location of the open end of the flue pipe or chimney.
If the problem persists contact your dealer and ask him to get your chimney and stove
installation checked.
Fire burning too quickly
This is usually caused by too much draft or air.
Firstly try reducing the air supply to the stove by closing down your air controls, if this
fails then you may have damage to the sealing.
Check the condition of the door sealing rope and the joints within the stove.
If neither of these solve the problem you may have too much draft on your chimney and
you may need to fit a damper valve into your flue system. You should not install a flue
damper without consulting a specialist. Never install a damper that can completely block
your flue or chimney. Contact your dealer to discuss this.

Chimney fire
Chimney fires occur when soot and creosote that have built up in the flue system ignite. If
the stove is operated properly and the flue checked and cleaned regularly then chimney
fires should not occur. These fires can be very dangerous and must be avoided. Try to
maintain good, hot fires in the stove whenever possible and at least once in every firing
open the air controls and allow the stove to burn on full for a short while until the entire fire
bed is glowing red. Check your flue system regularly for build-up of soot and creosote and
clean as necessary.
Chimney fires can be detected by sparks coming from the top of the chimney, a roaring
sound coming from the area of the stove or chimney or vibration in the stove or chimney.
In the event of a chimney fire, close the air controls, evacuate the building and call the fire
department. Do not relight the stove after a chimney fire until the stove and flue have been
checked and any necessary repairs have been carried out.
