Safety and Maintenance
1. Burn cord wood only, dry well seasoned wood. The denser or heavier the wood
when dry, the greater its heat value. This is why hardwoods are generally preferred.
Green or wet wood should not be used, as it will reduce heat output, as well as
contributing significantly to creosote buildup.
2. Remove ashes frequently and only when the stove is cold. Too much ash could
cause embers to roll out the door when it is opened. This may pose a fire hazard.
For proper operation, maintain a 25 mm minimum ash base.
3. If glass becomes darkened from slow burning or poor wood, it can readily be cleaned
with fireplace glass cleaner when stove is cold. Never scrape with an object or use
abrasive cleaners that might scratch the glass. The type and amount of deposit on
the glass is a good indication of the flue pipe and chimney buildup. A light brown
dusty deposit that is easily wiped off usually indicates good combustion and dry,
well-seasoned wood, therefore relatively clean pipes and chimney. On the other
hand, a black greasy deposit that is difficult to remove is a result of wet and green
wood and too slow a burning rate. This will also create heavy deposit buildup in the
chimney.
4. DOOR GASKETS - The gasket used on this unit (16 mm medium density fiberglass
rope) requires only light pressure to seal. This will prolong seal life. It is important
that the door seal be maintained in good condition. Periodically inspect seals and
replace if necessary. Follow instructions included in the door gasket kit (TN19.DGKIT
)obtainable from your nearest True North dealer.
5. DOOR GLASS - Do not slam loading door or otherwise impact glass. When closing
door, make sure that no logs protrude to impact the glass. If the glass gets cracked
or broken, it must be replaced before using the stove. Replacement glass can be
obtained from your dealer. Use ceramic glass only. Do not substitute with any
other type.
GLASS SIZE – 337mm x 235mm x 5mm thick.
To remove broken glass, undo the four retaining screws and remove the clamps, noting
position for re-assembly. Remove all pieces of glass. Be careful as they are very sharp.
Install new glass complete with gasket. Replace clamps and screws.
6. Do not store wood within heater installation clearances, or within the space required
for fuel loading and ash removal. Keep the area around the heater clean and free
of loose combustibles, furniture, newspapers, etc.
7. If the heater requires cleaning, use mild soap and water only. Use of abrasive
cleaners will void warranty.
8. Establish a routine for fuelling and firing the heater. Check daily for creosote buildup
until experience shows how often you need to clean the chimney to be safe.
9. Be aware that the hotter the fire, the less creosote is deposited. Weekly cleaning
may be necessary in mild weather, even though monthly cleaning is usually enough
in the coldest months when burning rates are higher.
10. Instruct all members of your family on the safe operation of the heater. Ensure they
have enough knowledge of the entire system if they are expected to operate it. Study
the section on chimney fires and the importance of following the steps outlined "In
Case of Chimney Fire".
WARNING:
Never use chemicals or any other volatile
liquidtostartafire. Donotburngarbage,
or flammable fluids such as gasoline,
naptha, or engine oil. We strongly
recommend that smoke detectors
be installed.
CAUTION:
• Tighten screws very carefully, do not
over-tighten
• Do not clean glass when hot
• Do not use abrasive cleaners on glass
WARNING:
Only use materials supplied by
manufacturer when doing maintenence
or replacements.

5055.552AS_040217-20 TN 20
Creosote
Formation and Need for Removal
When wood is burned slowly, it produces tar and other organic vapours, which combine with expelled moisture to form creosote.
The creosote vapours 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 periodically (at least once every two months) during the heating season
to determine if a creosote buildup has occurred. If creosote has accumulated (3 mm. or more), it should be removed to reduce the
risk of a chimney fire.
1. Highest smoke densities occur when a large amount of wood is added to a bed of hot coals and the air inlet is closed. The
heated wood generates smoke, but without ample air, the smoke cannot burn. Smoke-free, clean burning requires leaving the
air inlet relatively wide open, especially during the first 10 to 30 minutes after each loading, when most of the smoke generating
reactions are occurring. After 30 minutes or once the wood is fully charred, the air inlet can be turned down substantially
without excessive smoke generation. Wood coals create very little creosote-producing smoke.
2. The cooler the surface over which the wood smoke is passing, the more creosote will be condensed. Wet or green wood contributes
significantly to creosote formation as the excess moisture that is boiled off cools the fire, making it difficult for the tars and
gases to ignite, thus creating dense smoke and poor combustion. This moisture-laden smoke cools the chimney, compounding
the problem by offering the smoke the ideal place to condense.
In summary, a certain amount of creosote is inevitable and must be lived with. Regular inspection and cleaning is the solution.
The use of dry, seasoned wood and ample combustion air will help to minimize the buildup.
Chimney Fires
Excessive creosote build-up can cause a chimney fire. Creosote comes from tar and organic vapours released from a slow burning
wood fire. Flammable creosote will condense and accumulate in the lining of a relatively cool chimney. When ignited, this creosote
can result in an extremely hot fire.
Avoiding a Chimney Fire
There are two ways to avoid chimney fires:
1. Keep your chimney clear of creosote build-up by cleaning your chimney before each burn season, and as necessary
(accumulations of 3 mm or more) during the season.
2. Burn clean, well-seasoned wood only (seasoned at least one year). Avoid wet or green wood.
3. Do not burn household trash, cardboard, plastics, construction lumber, treated or beach wood (as these will corrode your
fireplace and void your warranty).
4. Do not leave the air inlet wide-open for extended periods of time.
5. Keep a fire extinguisher handy.
6. Prepare a home evacuation plan with a place outside where everyone is to meet.

If You Suspect a Chimney Fire
Signs of a chimney fire may be one or more of the following:
1. A roaring sound.
2. Vibration of the chimney.
3. Flames and sparks shooting out of the top of the chimney.
In Case of a Chimney Fire
1. Immediately close the air inlets on the stove.
2. Evacuate the home, and call the local fire department.
3. After the chimney fire has been extinguished, the chimney must be cleaned and checked for stress and cracking before
starting another fire. Also check combustibles around the chimney and roof.
Crate Removal
1. Carefully remove wood top and supports.
2. Remove plastic cover.
• Remove the retaining clip on the front of the baffle
before lighting for the first time

Operation
CAUTION:
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.
CAUTION:
Hot while in operation. Keep children, clothing and furniture away. Contact may cause skin burns.
WARNING: DO NOT USE FLAMMABLE LIQUIDS OR AEROSOLS TO START OR REKINDLE THE FIRE.
WARNING:DONOTUSEFLAMMABLELIQUIDS ORAEROSOLSINTHEVICINITYOFTHISAPPLIANCEWHENITISOPERATING.
WARNING: DO NOT STORE FUEL WITHIN HEATER INSTALLATION CLEARANCES.
WARNING: DO NOT OPERATE THIS APPLIANCE AS AN OPEN FIRE.
WARNING: OPEN AIR CONTROL (AND DAMPER WHEN FITTED) BEFORE OPENING FIRING DOOR.
Your TRUE NORTH heater is designed for maximum overall efficiency at a moderate firing rate. Overfiring is hazardous and a
waste of fuel. Too slow a burn contributes to creosote buildup and lowers combustion efficiency.
NOTE: Left and Right as referred to in this manual are considered your left and right when facing the front of the woodstove.
Wood Selection
This heater is designed to burn natural wood only. Higher efficiency and lower emissions generally result when burning air-dried
seasoned hardwoods, as compared to softwoods or too green or freshly cut hardwoods.
Wood should be properly air dried (seasoned) for six months or more. Wet or undried wood will cause the fire to smoulder and
produce large amounts of creosote. Wet wood also produces very little heat and tends to go out often.
DO NOT BURN :
• Salt water wood *
• Treated wood
• Wet or green wood
• Coal/charcoal
• Garbage/Plastic *
• Solvents
* These materials contain chlorides which will rapidly destroy metal surfaces and void warranty.
Do not burn anything but wood. Other fuels (eg. charcoal) can produce large amounts of carbon monoxide, a tasteless, odourless
gas that can kill. Under no circumstances should you attempt to barbecue in this heater.
This unit is not designed to be operated with the firing door open. In addition to the obvious hazard of sparks landing on combustibles,
an open fire door will cause the heater to draw air from the living space and possibly cause suffocation in an air tight home.

5055.552AS_040217-20 TN 20
How to Test Your Wood
Add a large piece of wood to the stove when it has a good large bed of coals. It is dry if it is burning on more than one side within
one minute. It is damp if it turns black and lights within three minutes. If it sizzles, hisses and blackens without igniting in five minutes
it is soaked and should not be burnt.
Lighting for the First Time
Curing of the Paint Finish
To achieve the best finish, the paint on your stove must be baked on. When burning your stove for the first 2-3 times it is very im-
portant that the room be well ventilated. Open all windows and doors. Smoke and fumes caused by the curing process may cause
discomfort to some individuals.
Lighting a Fire
WARNING: Never use chemicals or any other volatile liquid to start a fire.
1. Adjust air control to maximum firing position (start position) and open door.
2. Place crumpled newspaper in the centre of the heater and criss-cross with several pieces of dry kindling. Add a few small pieces
of dry wood on top.
3. Ignite the paper and close the door.
4. After the fire has established itself, open the door and add a few small logs. Close the door.
5. Begin normal operation after a good coal base exists and wood has charred.
Normal Operation
1. Set air control to a desired setting. If smoke pours down across the glass (waterfall effect) this indicates you have shut the
control down too soon or you are using too low a setting. As every home's heating needs vary (based on insulation, windows,
climate, etc.) the proper setting can only be found by trial and error and should be noted for future burns.
2. To refuel, adjust air control to high, and give the fire time to brighten. Open the door slowly, this will prevent backpuffing.
3. Use wood of different shape, diameter and length (up to 457mm). Load your wood and try to place the logs so that the air can
flow between them. Always use dry wood.
4. Do not load fuel to a height or in such a manner that would be hazardous when opening the door.
5. For extended or overnight burns, unsplit logs are preferred. Remember to char the wood completely on maximum setting before
adjusting air control for overnight burn.
WARNING: Always keep loading door closed when burning. This heater is not designed for open door
burning.
WARNING: No alteration or modification of the combustion air control assembly is permitted. Any
tampering will void warranty and could be very hazardous.
WARNING: Do not use grates or andirons to elevate the fuel. Burn directly on the fire bricks. Replace
broken or missing bricks. Failure to do so may create a hazardous condition.

14 5055.552AS_040217-20
TN 20
Restarting After Extended or Overnight Burns
1. Open door and rake hot embers towards the front of the heater. Add a couple
of dry, split logs on top of embers, close door.
2. Adjust air control to high (left position) and in just a few minutes, logs should
begin burning.
3. After wood has charred, reset air control to desired setting.
4. To achieve maximum firing rate, set control to high (left position). Do not use this
setting other than for starting or preheating fresh fuel loads.
Proper Draft
1. 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.
2. Too muchdraftmaycause excessivetemperatures in theappliance. Anuncontrollable
burn or a glowing red stove part or chimney indicates excessive draft.
3. Inadequate draft may cause backpuffing into the room and plugging of the chimney.
Smoke leaking into the room through appliance and chimney connector joints
indicates inadequate draft.
Ash Removal
Whenever ashes get 75 mm to 100 mm inches deep in your firebox, and when the fire
has burned down and cooled, remove excess ashes. Leave an ash bed approximately
(25 mm) deep on the firebox bottom to help maintain a hot charcoal bed.
Disposal of Ashes
Ashes should be placed in a metal container with a tight fitting lid. The closed container
of ashes should be placed outside 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 a closed
container until all cinders have thoroughly cooled. Other waste should not be placed
in this container.
DONOTOVERFIRETHISHEATER:
Attempts to achieve heat output rates
that exceed heater design specifications
can result in permanent damage to the
heater and chimney.
CAUTION:
Ashes are to be removed only when the
heater is cold.

Installation
1. Insert one half of baffle board above the two back baffle tubes inside the firebox, slide over to the right and allow to rest on
the baffle air assembly.
2. Ensure that the second half is inserted to allow the two cuts in the baffle boards to overlap. Insert the other half of the baffle
board and allow to rest on the left side baffle air assembly.
3. With the holes facing forward and the notch to the left side, insert a baffle tube into the hole in the baffle air channel on the
right at an angle and then raise and insert into the opposite hole on the left side baffle air assembly.
4. With a set of vise-grips, grasp the baffle tube on the left, slightly away from the baffle air assembly. While squeezing tightly,
use a hammer to hit the pliers and push the tube to the left to engage the tube in the hole on the left.
5. Repeat steps #3 & #4 with the remaining baffle tube.
6. Slide the baffle board halves together and then separate slightly to ensure there are no gaps on either side of the baffle
board.
