Safety and Maintenance
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.
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.
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.
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.
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.
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.
If the heater requires cleaning, use mild soap and water only. Use of abrasive
cleaners will void warranty.
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.
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.
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
liquidtostart afire. 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 maintenance
or replacements.

Maintenance Checks
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 -Coal/charcoal
-Treated wood -*Garbage/Plastics
-Wet or green wood -Solvents
* These materials contain chlorides which will rapidly destroy metal surfaces and void warranty.
Do not burn anything but wood. Other fuel, e.g. 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.
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.

Creosote
Formation and Need for Removal
1. 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.
2. 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.
3. 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.
4. 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.
Avoiding a Chimney Fire
Excessive creosote build-up can cause a chimney fire. During a fire the inside temperatures in a chimney can exceed 1100 degrees
C. This causes much higher than normal temperatures in the chimney and on its exterior surfaces thus ignition of nearby or touching
combustible material is more likely during a chimney fire.
1. Keep your chimney clear of creosote build-up by cleaning your chimney before each burn season, and as necessary (accumula-
tions 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 use the heater as an incinerator or over-fire as it may ignite chimney fires. These are hot fires, such as when burning
household trash, cardboard, Christmas tree limbs, or even ordinary fuel wood; (eg. With a full load on a hot bed of coals and with
the air inlet wide open)
• Have a fire extinguisher handy. Contact your local fire authority for further information on how to handle a chimney fire. It is
most important that you have a clearly understood plan on how to handle a chimney fire.
Signs of a chimney fire may be one or more of the following:
- Flames and sparks shooting out of the top of the chimney
- A roaring sound
- Vibration of the chimney
In the event of a Chimney Fire
1. Prepare to evacuate to ensure everyone’s safety. Have a place outside where everyone is to meet.
2. Close down the damper on stove.
3. Call local fire department.
4. After the chimney fire is out, the chimney must be cleaned and checked for stress and cracking before starting another fire.
Also check combustibles around chimney and the roof. This should be done by a certified inspector/chimney sweep.

Lighting for the first time
Curing of the New Paint Finish
When burning your stove for the first 2-3 times it is very important 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 the Fire
1) Adjust air control, located under the Ash Shelf, to the “High” position (pushed to the far left)
and open door.
2) Place crumpled newspaper in the centre of the heater and crisscross 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 door.
5) Begin normal operation after a good coal base exists and wood has charred.
Your Pacific Energy heater is designed for maximum overall efficiency at a moderate firing rate.
Over firing is hazardous and a waste of fuel. Too slow a burn contributes to creosote buildup
and lowers combustion efficiency.
Normal Operation
1. To refuel, adjust air control to “High” position (pushed to the far left) and give the fire time
to brighten. Open door slowly, this will prevent smoke from rolling out.
2. Use wood of different shape, diameter and length (up to 450mm). Load your wood endwise
and try to place the logs so that air can flow between them. Always use dry wood.
3. Do not load fuel to a height or in such a manner that would be hazardous when opening the
door.
4. Set air control to 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 (i.e. insulation, windows, climate, etc.), The proper
setting can only be found by trial and error and should be noted for future burns.
5. For extended or overnight burns, un-split logs are preferred. Remember to char the wood
completely on the “High” setting before adjusting air control for overnight burn.
Experience will give you the right settings for proper combustion and efficient burning.
Remember, the air inlet setting is affected by variables such as type of wood, outside
temperature, chimney size and weather conditions. With practice, you will become proficient in
operating your heater and will obtain the performance for which it was designed.
WARNING: 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 in use.
Do not store/place wood
or other combustibles
within the required clear-
ances surrounding the
unit.
DO NOT OVERFIRE THIS
HEATER: Attempts to
achieve heat output rates
that exceed heater design
specifications can result in
permanent damage to the
heater and chimney.
WARNING: No alteration
or modification of the
combustion air control as-
sembly is permitted. Any
tampering will void war-
ranty and could be very
hazardous.
Operation

For your protection
against shock hazard, use
only a properly grounded
outlet that will accept a
grounded plug.

5055.553AS_131216-20 TN 20 INS.AS
Restarting after Overnight Burn
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 the “High” position (pushed to the far left) and in just a few minutes,
logs should begin burning.
3. After wood has charred, reset air control to desired setting.
4. When burning at a slow rate for extended periods, occasionally maintain a strong fire
under supervision for a couple of hours to remove firebox and chimney deposits as well as
any of the deposits on the glass.
Proper Draft
• 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 uncontrollable burn
or a glowing red stove part or chimney indicates excessive draft.
• Not enough draft may cause back puffing into the room and plugging of the chimney.
Smoke leaking into the room through appliance and chimney connector joints indicates
inadequate draft.
Blower Operation
The Insert comes equipped with a two speed circulating air blower. The Blower switch is
located on the lower right side edge of the Surround Panel.
To turn ON the blower, push the fan speed control switch to Low or High.
Suggested settings:
- Combustion air control setting of “Low”(all the way to the right), operate blower speed
control on “Low” (one line on switch).
- Combustion air control “Medium”, or greater, operate blower speed on high.(Two Lines on
switch)
To turn OFF, push the switch to the middle position.
WARNING: Do not use
grates or andirons to
elevate the fuel. Burn
directly on the firebricks.
Replace broken or missing
bricks. Failure to do so
may create a hazardous
condition.
WARNING: Always keep
loading door closed
when burning, except as
instructed during start-
up. This heater is not
designed for open door
burning.
CAUTION: Unit hot while
in operation. Parts of the
appliance, especially the
external surfaces, will
be hot to touch when in
operation. Keep children,
clothing and furniture
away. Contact may cause
skins burns.

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.
7. Push baffle board tight against the rear of the firebox.
