SAFETY PRECAUTIONS
Creosote-Formation and need for removal. When wood is
burned slowly it produces tar and other organic vapors that
combine with expelled moisture to form creosote. The creosote
vapors condense in a relatively cool 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.
When grease or creosote have accumulated, it should be
removed to reduce the risk of fire.
Do not use accessories not specified for use with this appliance.
Verify that the oven is properly installed before firing the oven
for the first time.After reading these instructions, if you have any
doubt about your ability to complete your installation properly,
you must obtain the services of a professional licensed installer
familiar with all aspects of safe and correct installation. DO NOT
use temporary or makeshift compromised during installation.
There must be NO DEVIATION ORALTERATION OFANY
KIND from the very specific instructions spelled out in this
instruction manual as it pertains to the installation of this wood
oven. NO EXCEPTIONS.
DO NOT ELEVATE THE OVEN BY ANY MEANS (i.e.
bricks under legs, cement blocks). Oven must set directly
upon the solid-surface non-combustible floor as specified in
this manual.
DO NOT MODIFY THIS OVEN IN ANY WAY! Assemble
only with original parts as supplied and shown in this manual.
DO NOT OPERATE AN OVEN THAT IS MISSING
PARTS! If any parts are missing or defective, please notify the
dealer or manufacturer immediately. Replace missing, broken,
or worn parts with factory original or equivalent parts only.
Do not connect a wood burning appliance to an aluminum type B
gas vent. This is not safe. Use approved masonry or a UL listed
UL 103HT / ULC-S629 Residential Type and Building Heating
Appliance chimney. Use a 6”/152mm diameter chimney, that
is high enough to give a good draft. (See specifications in the
VENTILATION section).
Follow these guidelines to prevent this colorless, odorless
gas from poisoning you, your family or others.
Know the symptoms of carbon monoxide poisoning: headache,
dizziness, weakness, nausea, vomiting, sleepiness, and
confusion. Carbon monoxide reduces the blood’s ability to
carry oxygen. Low blood oxygen levels can result in loss of
consciousness and death.
See a doctor if you or others develop cold or flu-like symptoms
while cooking or in the vicinity of this appliance. Carbon
monoxide poisoning, which can easily be mistaken for a cold
or flue, is often detected too late.
Alcohol consumption and drug use increase the effects of carbon
monoxide poisoning.
Carbon monoxide is especially toxic to mother and child during
pregnancy, infants, the elderly, smokers, and people with blood
or circulatory system problems, such as anemia, or heart disease.

CHIMNEY CONNECTOR (STOVE PIPE)
Your chimney connector and chimney must have the same diameter as the appliance outlet (6”). If this is not the case, we recommend
you contact your dealer in order to insure there will be no problem with the draft.
The stove pipe must be made of aluminized or cold roll steel with a minimum thickness of 0.021” or 0.53 mm. It is strictly forbidden
to use galvanized steel.
Your smoke pipe should be assembled in such a way that the male section (crimped end) of the pipe faces down. Attach each of
the sections to one another with three equidistant metal screws. Seal with furnace cement.
The pipe must be short and straight. All sections installed horizontally must slope at least 1/4 inch per foot, with the upper end of
the section toward the chimney. Any installation with a horizontal run of chimney pipe must conform to NFPA 211. You may contact
NFPA (National Fire Protection Association) and request the latest edition of the NFPA Standard 211.
To insure a good draft, the total length of the coupling pipe should never exceed 8’ to 10’ (2.4m to 3.04 m). (Except for cases of
vertical installation, cathedral-roof style where the smoke exhaust system can be much longer and connected without problem to
the chimney at the ceiling of the room).
There should never be more than two 90 degrees elbows in the smoke exhaust system.
Installation of a “barometric draft stabilizer” (fireplace register) on a smoke exhaust system is prohibited.
Furthermore, installation of a draft damper is not recommended. Indeed, with a controlled combustion wood appliance,
the draft is regulated upon intake of the combustion air in the appliance and not at the exhaust.

CHIMNEY
Your wood appliance may be hooked up with a 6” factory built or masonry chimney. If you are using a factory built chimney,
it must comply with UL 103 or CSA-B365 standard; therefore, it must be a Type HT (2100°F). It is extremely important that it be
installed according to the manufacturer’s specifications.
If you are using a masonry chimney, it is important that it be built in compliance with the specifications of the National Building
Code. It must be lined with fire clay bricks, metal or clay tiles sealed together with fire cement. (Round flues are the most efficient).
The interior diameter of the chimney flue must be identical to the appliance smoke exhaust. A flue which is too small may cause
draft problems, while a large flue favours rapid cooling of the gas, and hence the build-up of creosote and the risk of chimney fires.
Note that it is the chimney and not the appliance which creates the draft effect; your appliance’s performance is directly
dependent on an adequate draft from your chimney.
The following recommendations may be useful for the installation of your chimney:
1. Do not connect this unit to a chimney flue serving another appliance.
2. It must rise above the roof at least 3’ (0.9m) from the uppermost point of contact.
3. The chimney must exceed any part of the building or other obstruction within a 10’ (3.04m) distance by a height of 2’ (0.6m).
4. Installation of an interior chimney is always preferable to an exterior chimney. Indeed, the interior chimney will, by definition,
be hotter than an exterior chimney, being heated up by the ambient air in the house. Therefore, the gas which circulates will
cool more slowly, thus, reducing the build-up of creosote and the risk of chimney fires.
5. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
6. Using a fire screen at the extremity of the chimney requires regular inspection in order to insure that it is not obstructed thus,
blocking the draft. It should be cleaned when used regularly.
7. Exterior chimney should be double or triple wall.

9
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.

OVEN UTILIZATION
It is EXTREMELY IMPORTANT that you use DRY WOOD only in your wood oven. The wood should have dried for 9 to 15
months, such that the humidity content (in weight) is reduced below 20% of the weight of the log. It is very important to keep in mind
that even if the wood has been cut for one, two, or even more years, it is not necessarily dry if it has been stored in poor conditions.
Under extreme conditions it may rot, instead of drying. This point cannot be over stressed; the vast majority of the problems related
to the operation of a wood oven is caused by the fact that the wood used was too damp or has dried in poor conditions. These
problems can be:
- Ignition problems
- Creosote build-up causing chimney fires
- Low energy yield
- Blackened windows
- Incomplete log combustion
Smaller pieces of wood will dry faster. All logs exceeding 6” in diameter should be split. The wood should not be stored directly
on the ground. Air should circulate through the cord. A 24” to 48” air space should be left between each row of logs, which should
be placed in the sunniest location possible. The upper layer of wood should be protected from the elements but not the sides.
TESTING YOUR WOOD
When the oven is thoroughly warmed, place one piece of split wood (about five inches in diameter) perpendicular to the door on
the bed of red embers.
Keep the air control full open by sliding it right and close the door. If ignition of the piece is accomplished within 90 seconds from
the time if was placed in the oven, your wood is correctly dried. If ignition takes longer, your wood is damp.
If your wood hisses and water or vapor escapes at the ends of the piece, your wood is soaked or freshly cut. Do not use this wood
in your oven. Large amounts of creosote could be deposited in your chimney, creating potential conditions for a chimney fire.
Your oven was designed to burn wood only; no other materials should be burned. Waste and other flammable materials should
not be burned in your oven. Any type of wood may be used in your oven, but specific varieties have better energy yields than others.
Please consult the following table in order to make the best possible choice.

12
THE FIRST FIRES
The fresh paint on your oven needs to be cured to preserve its quality. Once the fuel charge is properly ignited, only burn small
fires in your oven for the first four hours of operation. Never open the air control more than necessary to achieve a medium burn rate.
Make sure that there’s enough air circulation while curing the oven. The odors may be smelled during the first 3 or 4 fires. During
curing people and animals with lung problems should take caution.
IGNITION
Aer making sure that the oven air intake controls are fully open (completely slide to the right), place several rumpled sheets of
paper in the center of the combustion chamber. Place 8 to 10 pieces of small dry kindling wood over the paper in the form of a tent.
You may also place a few pieces of cooking wood, but choose the smaller ones. No chemical product should be used to light the fire.
Before igniting the paper and kindling wood, it is recommended that you warm up the chimney. This is done in order to avoid
back draft problems often due to negative pressure in the house. If such is the case, open a window slightly near the oven and twist
together a few sheets of newspaper into a torch. Light up this paper torch and hold it as close as possible to the back of the combustion
chamber to warm up the chimney. Once the updraft movement is initiated, you are ready to ignite the oven by lighting the paper and
kindling wood inside the combustion chamber.
When you have achieved a good bed of hot embers, we recommend the following burn procedures:
COOKING
Controlled combustion is the most efficient technique for wood cooking because it enables you to select the type of combustion
you want for each given situation. The wood will burn slowly if the combustion air intake control is adjusted to reduce the oxygen
supply in the combustion chamber to a minimum. On the other hand, wood will burn quickly if the air control is adjusted to admit a
larger quantity of oxygen in the combustion chamber. Real operating conditions may give very different results than those obtained
during testing according to the species of wood used, its moisture content, the size and density of the pieces, the length of the chimney,
altitude, and outside air temperature.
DAMPERS
The oven has two air control dampers. The lower damper controls the Primary combustion air into the combustion chamber. The
upper air damper controls the air wash across the combustion chamber window as well as allowing additional combustion air to enter
the firebox. It is recommended that the air wash damper be adjusted so that the window remains free of soot buildup. Then, adjust
the primary air damper to control the fire.
CAUTION: Never alter the damper slide or the adjustment range to increase firing for any reason. Doing so could result
in oven damage and will void your warranty.

13
WARNINGS
NEVER OVERFIRE YOUR OVEN. IF ANY PART OF THE OVEN STARTS TO GLOW RED, OVER FIRING IS
HAPPENING. READJUST THE AIR INTAKE CONTROL AT A LOWER SETTING.
THE INSTALLATION OFA LOG CRADLE OR GRATES IS NOT RECOMMENDED IN YOUR WOOD OVEN. BUILD
FIRE DIRECTLY ON FIREBRICK.
NEVER PUT WOOD ABOVE THE FIREBRICK LINING OF THE FIREBOX.
RELOADING
Once you have obtained a good bed of embers, you should reload the unit. In order to do so, open the air controls to maximum
a few seconds prior to opening the oven’s door. Then, proceed by opening the door very slowly; open it one or two inches for 5
to 10 seconds, before opening it completely to increase the draft and thus, eliminate the smoke which is stagnant in a state of slow
combustion in the oven. Then, bring the red embers to the front of the oven and reload the unit.
For optimal operation of your wood oven, we recommend you to operate it with a wood load approximately equivalent to the
height of fire bricks.
It is important to note that wood combustion consumes ambient oxygen in the room. In the case of negative pressure, it is a good
idea to allow fresh air in the room, either by opening a window slightly or by installing a fresh air intake system on an outside wall.
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
connector and chimney should be inspected at least once every two months during the season to determine if a creosote build-up has
occurred. If creosote has accumulated (3mm or more), it should be removed to reduce the risk of a chimney fire.
We strongly recommend that you install a magnetic thermometer on your smoke exhaust pipe, approximately 18” above the oven.
This thermometer will indicate the temperature of your gas exhaust fumes within the smoke exhaust system. The ideal temperature
for these gases is somewhere between 275°F and 500°F. Below these temperatures, the build-up of creosote is promoted. Above 500
degrees, heat is wasted since a too large quantity is lost into the atmosphere.
TO PREVENT CREOSOTE BUILD UP
• Always burn dry wood. This allows clean burns and higher chimney temperatures, therefore, less creosote deposit.
• Leave the air control full open for about 5 min. every time you reload the oven to bring it back to proper operating
temperatures.
• Always check for creosote deposit once every two months and have your chimney cleaned at least once a year.
If a chimney or creosote fire occurs, close all dampers immediately. Wait for the fire to go out and the oven to cool. Then,
inspect the chimney for damage. If no damage results, perform a chimney cleaning to ensure there is no more creosote
deposits remaining in the chimney.
ASH DISPOSAL
Ashes should be removed from the oven every few days or when ashes get to 2 to 3 inches deep. Always empty the oven when
it is cold, such as in the morning. Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes
should be placed on a non combustible 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. Other waste shall not be placed in this container.
CAUTIONS:
• ASHES COULD CONTAIN HOT EMBERS EVEN AFTER TWO DAYS WITHOUT OPERATING THE OVEN.
• THE ASH PAN CAN BECOME VERY HOT. WEAR GLOVES TO PREVENT INJURY.
• NEVER BURN THE OVEN WITH THE ASH TRAP OPEN. THIS WOULD RESULT IN OVER FIRING THE
OVEN. DAMAGE TO THE OVEN AND EVEN HOUSE FIRE MAY RESULT.

14
MAINTENANCE
GLASS
• Inspect and clean the glass regularly in order to detect any cracks. If you spot one, turn the oven off immediately. Do not abuse
the glass door by striking or slamming shut. Do not use the oven if the glass is broken.
• If the glass on your oven breaks, replace only with the glass supplied from your dealer. Never substitute other materials for the
glass.
• To replace the glass, remove the screws retaining the glass mouldings inside the door.
1) Remove the mouldings and replace the damaged piece with a new one.
2) Perform the procedure backwards after replacing. When replacing the glass, you should change the glass gasket to make
sure you keep it sealed.
• Never wash the glass with a product that may scratch. Use a specialized product, available in the stores where wood ovens are
sold. The glass should be washed only when cold.
GASKETING
It is recommended that you change the door gasket (which makes your oven door air tight) once a year, in order to insure good
control over the combustion, maximum efficiency and security. To change the door gasket, simply remove the damaged one. Carefully
clean the available gasket groove, apply a high temperature silicone sold for this purpose, and install the new gasket. You may light
up your oven again approximately 24 hours after having completed this operation.
Press the gasketing into the groove. Never streach the gasket.
Your wood oven is a high efficiency oven and therefore requires little maintenance. It is important to perform a visual inspection
of the oven every time it is emptied, in order to insure that no parts have been damaged, in which case repairs must be performed
immediately. Inspect and clean the chimney and connector pipe periodically for creosote buildup or obstructions.
WARNING:
NEVER OPERATE THE OVEN WITHOUT A GASKET OR WITH A BROKEN ONE. DAMAGE TO THE OVEN OR
EVEN HOUSE FIRE MAY RESULT.
PAINT
Only clean your oven with a dry soft cloth that will not harm the paint finish. If the paint becomes scratched or damaged, it is
possible to give your wood oven a brand new look, by repainting it with a 1200° F heat resistant paint. For this purpose, simply scrub
the surface to be repainted with fine sand paper, clean it properly, and apply two (2) thin coats of paint successively.
COOKING CHAMBER BRICK
The fire brick in the cooking chamber is very porous and may absorb any cleaning chemicals used. For this reason, we recommend
placing the cooking chamber fire brick in the combustion chamber and lighting a small fire to clean the fire brick. Doing this will
burn off any food particulates and sanitize the brick for further use.
SEASONAL START UP
Prior to starting the first fire of the heating season, check the outside area around the exhaust and air intake systems for obstructions.
Clean and remove any fly ash from the exhaust venting system. Clean any screens on the exhaust system and on the outside air
intake pipe. Turn all of the controls on and make sure that they are working properly. This is also a good time to give the entire
appliance a good cleaning throughout.
SEASONAL SHUTDOWN
The exhaust system should be thoroughly cleaned.
REMOVE ANY ASH OR UNBURNED WOOD. CLEAN
COOKING CHAMBER AND BAFFLE.
MAINTENANCE SCHEDULE
Use the following as a guide under average use conditions.
Gaskets around door and door glass should be inspected

When your appliance acts out of the ordinary, the first reaction is to call for help. This guide may save time and money by enabling
you to solve simple problems yourself. Problems encountered are often the result of only five factors.
1. Poor fuel;
2. Poor operation or maintenance;
3. Poor installation;
4. Component failure;
5. Factory defect.
You can usually solve those problems related to 1 and 2. Your dealer can solve problems relating to 3, 4 and 5. Refer to the repair
parts diagrams to help locate indicated parts.
Never try to repair or replace any part of the oven unless instructions for doing so are given in this manual. All other work should
be done by a trained technician.
TROUBLE SHOOTING GUIDE
SMOKE SMELL COMING BACK INTO THE HOME
Possible Causes: Possible Remedies:
1. There is a leak in the vent pipe system. Inspect all vent pipe connections. Make sure they are sealed
with RTV silicone that has a temperature rating on 500 degree F
or higher. Also, seal joints with UL-181-AP foil tape.
Because it is a wood-burning device, your oven may emit a faint wood-burning odor. If this increases beyond normal, or if you
notice an unusual soot build-up on walls or furniture, check your exhaust system carefully for leaks. All joints should be properly
sealed. Also clean your appliance, following instructions in “MAINTENANCE”. If problem persists, contact your dealer.
• GLASS “SOOT’S” UP AT A VERY FAST RATE
• FLAME IS LAZY, DARK, AND HAS BLACK TIPS
Possible Causes: Possible Remedies:
1. Appliance or vent pipe is dirty, which restricts airflow. Follow all cleaning procedures in the maintenance section of
the owner’s manual.
2. Vent pipe installed improperly. Check to make sure the vent pipe has been installed according
to the criteria in the owner’s manual.
3. Air damper is set too far closed. Open the air damper and try to burn the unit again.
5. Air damper is broken. Visually inspect the damper assembly. Make sure the damper
plate is attached to the damper rod. When the damper rod is
moved, the plate should move with it.

FLOOR PROTECTION
This heater must have a non-combustible floor protector (ember protection) installed beneath it if the floor is of combustible
material. If a floor pad is used, it should be UL listed or equal. If the floor protector is not UL Listed, then it must comply with AS/
NZS 2918-2001. The requirements for AS/NZS 2918-2001 Edition are:
1) “The floor protector shall extend either to a distance of not less than 500 mm beyond any part of the appliance or a lesser distance
at which it forms an abutment with a wall or heat shield.” (AS/NZS 2918-2001 3.3.3)
2) “be constructed to a thickness of not less than 75 mm (see Clause 3.3.4) of masonry or concrete laid on a supporting sheet of
continuous heat-resistant material. The floor protector shall be separated from the floor by means of heat resistant spacers forming
an air gap of not less than 25 mm between the floor protector and the floor or floor covering (see Figure 3.3). Total plan area of
the air gap shall be not less than 90 percent of the area of the floor protector. Openings shall be provided along at least one pair
of opposite edges of the floor protector to ventilate the air gap.” (AS/NZS 2918-2001 3.3.3 a ii)
