Efficiency and BTU Output

4 TN 20B INSERT 110618-28
©PACIFIC ENERGY FIREPLACE

1. Burn only dry and well seasoned cord 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 will cause a rapid buildup
of creosote. If you feel it is necessary to burn wet or unseasoned wood, do so only with the air inlet set
open enough to maintain a good strong re and fairly high chimney temperatures. Do not attempt to burn
overnight using green wood or wet wood. Wet wood can cause up to 25% drop in heater output, as well
as contributing signicantly to creosote buildup.
2. Remove ashes frequently. Embers can roll out the door and create a re hazard. Maintain a 1"(25mm)
minimum ash base.
3. If glass becomes darkened through slow burning or poor wood, it can readily be cleaned with replace
glass cleaner when stove is cold. Never scrape with an object that might scratch the glass. The type and
amount of deposit on the glass is a good indication of the ue pipe and chimney buildup. A light brown
dusty deposit that is easily wiped off usually indicates good combustion and dry, well-seasoned wood and
therefore relatively clean pipes and chimney. On the other hand, a black greasy deposit that is difcult to
remove is a result of wet and green wood and too slow a burning rate. This heavy deposit is building up at
least as quickly in the chimney.
4. DOOR GASKETS - The gasket used for the True North (5/8"(16mm) medium density berglass rope)
requires only light pressure to seal. This will prolong seal life. It is important that the door seal be main-
tained in good condition. Periodically inspect seals and replace if necessary. Follow instructions included
in the Gasket kit 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 9-1/4"(235mm) x 13-1/4"(337mm) x
5 mm. Ceramic glass only. Do not substitute with any other type.
• -To remove broken glass, undo the four retaining screws and remove clamps, noting position for
re-assembly. Remove all particles of glass. Be careful as they are very sharp. Replace Gasket if damaged.
Install new glass. Replace clamps and screws.
CAUTION:
- do not overtighten, tighten screws very carefully
- do not clean glass when hot
- do not use abrasive cleaners on glass
6. The openings for combustion air must be kept clear of excessive ash buildup which will block air ow.
This area is at the front of the rebox or at your fresh air intake.
7. 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.
Safety and Maintenance
WARNING: Never use chemicals or any other volatile liquid to start a fire. Do not burn garbage, or
flammable fluids such as gasoline, naptha, or engine oil.
WARNING: ONLY USE MATERIALS SUPPLIED BY MANUFACTURER WHEN DOING MAINTENANCE OR
REPLACEMENTS.

Maintenance Checks
Check the following parts for damage such as cracks, excessive corrosion, burned out sections and exces-
sive warping:
Weekly:
• Firebrick - Visual, for cracking.
• Door Gasket - sagging, placement, damage.
Monthly
• Brick rail tabs and brick rails.
• Back side of airwash chamber.
• Boost tube opening.
• Top bafe boards.
• Bafe Tubes.
As Needed
• It is recommeded that the chimney be inspected a minimum of every 2 months and cleaned as needed a
minimum of 2 times a year.
When Cleaning the Chimney System:
• Top heat shield and mounting bolt.
• Brick Rails.
• Manifold.
- Replace the bafe tubes if they show signs of cracking or breakage.
- Please contact your Dealer for replacement parts if you experience any of the damage listed above.
Continuing to operate your stove with broken parts may accelerate damage to other parts and will void your
warranty
Blower:
• The blower should be cleaned out a minimum every six months by using a vacuum on the inlets, grills and
around the motor to remove any dust and debris. See page 20 for instructions.
8. Establish a routine for the fuel, wood burning and Lighting techniques. Check daily for creosote buildup in
the rebox, until you are experienced and are operating the stove cleanly and safely.
9. Be aware that the hotter the re, the less creosote is deposited. More frequent chimney cleaning may be
necessary in mild weather or when burning “wet” or unseasoned wood.
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. Stress the section on chimney res and
the importance of following the steps outlined “In Case of Chimney Fire”.

Chimney Smoke and Creosote Formation
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 ue of a slow burning re. As
a result, creosote residue accumulates on the ue lining. When ignited, this creosote makes an extremely hot
re.
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 re.
• Highest smoke densities and emissions occur when a large amount of wood is added to a bed of hot
coals and the air inlet is closed off too quickly. Smaller fuel loads, (two or three logs at a time) and leaving
the air inlet relatively wide open, especially during the rst 10 to 30 minutes after each loading, when most
of the smoke generating reactions are occurring will promote smoke-free, clean burning. After 30 minutes
or so, the air inlet can be turned down substantially without excessive smoke generation.
• Wet or green wood contributes signicantly to creosote formation as the excess moisture that is boiled
off, cools the re, making it difcult for the tars and gases to ignite, thus creating dense smoke and poor
combustion. This moisture-laden smoke cools the chimney, compounding the problem.
In summary, a certain amount of creosote is inevitable. Regular inspection and cleaning is the solution. The
use of dry, seasoned wood and ample combustion air will help to minimize annoying smoke emissions and
creosote buildup.
Chimney Fires
The dangerous side effect of excessive creosote buildup is a chimney re. This causes much higher than
normal temperatures in the chimney and on its exterior surfaces. Temperatures inside the chimney can
exceed 2000°F (1100°C). Ignition of nearby or touching combustible material is more likely during a chimney
re. Proper clearances are critical to prevent damage during such a re.
Chimney res are easy to detect; they usually involve one or more of the following:
• Flames and sparks shooting out of the top of the chimney
• A roaring sound
• Vibration of the chimney
•
Avoid a Chimney Fire
1. Burn wood cleanly. Do not burn wet wood or turn down the unit too quickly after loading.
2. Do not let creosote build up to a point where a chimney re is possible.
3. Do not have res in the heater that may ignite chimney res. These are excessively hot res, such as when
burning household trash, cardboard, Christmas tree limbs, or even ordinary fuel wood; (e.g. With a full
load on a hot bed of coals and with the air inlet wide open for more time than is needed to completely
char a fresh fuel load.)
4. The Chimney and connector pipe should be inspected /cleaned periodically.

In the event of a Chimney Fire
Have a re extinguisher handy. Contact your local, Municipal or State/Provincial re authority for further
information on how to handle a chimney re. It is most important that you have a clearly understood plan
on how to handle a chimney re.
1. Close down the air inlet on the stove.
2. Call the local re department.
3. Prepare to evacuate to ensure everyone's safety. Have a well understood plan of action for evacuation.
Have a place outside where everyone is to meet.
4. After the chimney re is out, the chimney must be cleaned and checked for stress and cracks before
starting another re. Also check combustibles around the chimney and the roof. The services of a
competent or certied installer, (certied by the Wood Energy Technical Training program (WETT) - in
Canada, National Fireplace Institute (NFI) - in U.S.A., are strongly recommended.
Wood Selection
This heater is designed to burn natural wood only. Higher efciency and lower emissions generally result when
burning air-dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods.
Wood should be properly air dried (seasoned) for six months or more. Wet or unseasoned wood will
cause the fire to smoulder and produce large amounts of smoke and creosote. Wet wood also pro-
duces very little heat and tends to go out often. Wood should be stored under cover away from open
flame or heat sources.
DO NOT BURN:
• Salt water wood * • Treated wood
• Wet or green wood • Coal/charcoal
• Garbage* • Solvents
• Lawn clippings/yard waste • Unseasoned wood
• Railroad ties • Manure or animal remains
• Materials containing rubber, including tires • Materials containing plastic
• Waste petroleum products, paints or paint thin-
ners, or asphalt products
• Materials containing asbestos
• Construction or demolition debris • Paper products, cardboard, plywood, or
particleboard.
* These materials contain chlorides which will rapidly destroy metal surfaces and void warranty.
Burning these materials may result in the release of toxic fumes or render the heater ineffective and cause
excessive smoke.
The prohibition against burning these materials does not prohibit the use of re starters made from paper,
cardboard, saw dust, wax and similar substances for the purpose of starting a re in an affected wood heater.
Do not burn anything but cordwood. Other fuels, 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.

CAUTION: Hot while in operation. Keep children, clothing and furniture away. Contact may cause skin
burns.
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.
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.
Lighting a Fire
** Remove the retaining clip on the front of the Baffle Tubes and Board before lighting for the first time.
1. Move air control lever to the left-most position (maximum ring rate) 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 leave the door ajar approximately 1/2"(13mm) - 1"(25mm) until the wood kindling is
fully engulfed in ame. DO NOT LEAVE UNATTENDED.
4. After the kindling is fully engulfed add a few small logs. Close 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. The wide range control panel
makes nding the desired setting for your application easy. 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.
2. To refuel, adjust air control to high, and give the re time to brighten. Open the door slowly, this will pre-
vent back pufng.
3. Use wood of different shape, diameter and length (up to 18" (457mm)). Load your wood and try to place
the logs so that the air can ow 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.
Operation

PRODUCTS LTD.
WARNING: 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 the operating instructions in this manual.
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 (control lever to the left) 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 ring rate, set air control lever to the left-most position. Do not use this setting other
than for starting or preheating fresh fuel loads.
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.
Your True North heater is designed for maximum overall efciency at a moderate ring rate. Over ring the
appliance will shorten the life of the product. Failure to rectify an over ring condition can be hazardous and
may void the manufacturer’s warranty. Too slow a burn may contribute to creosote buildup and lowers com-
bustion efciency.
Heat Output
Experience will give you the right settings for proper combustion and efcient burning. Remember that the
correct air inlet setting is affected by variables such as type of wood, outside temperature, chimney size and
weather conditions. With practice, you will become procient in operating your heater and will obtain the
performance for which it was designed.
Proper Draft
Draft is the force that pulls air into the appliance and 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.
• Inadequate draft may cause back pufng into the room and plugging of the chimney. Smoke leaking into
the room through appliance and chimney connector joints indicates inadequate draft.
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 ve minutes it is soaked and should not be burned.

PRODUCTS LTD.
Curing of the Paint Finish
To achieve the best nish, the paint on your stove must be baked on. Follow the Paint Curing instructions.
When burning your stove for the rst 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.
Ash Removal
Caution: Ashes are to be removed only when the heater is cold. Whenever ashes get 3"(76mm) to 4"(102mm)
deep in your rebox, and when re has burned down and cooled, remove excess ashes. Leave an ash bed
approximately 1" (25 mm) deep on the rebox bottom to help maintain a hot charcoal bed.
Disposal of Ashes
Ashes should be placed in a metal container with a tight tting lid. The closed container of ashes should be
placed outside on a non-combustible oor or on the ground, well away from all combustible materials, pend-
ing nal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be
retained in closed container until all cinders have thoroughly cooled. Other waste should not be placed in this
container.
Blower Operation
The Insert comes equipped with a variable speed circulating air blower. The Blower Control is located on the
lower right side edge of the Surround panel.
To operate the blower, rotate the fan speed control clockwise to turn ON then continue to rotate to nd a
desired setting.
Suggested settings:
- Combustion air control setting of “Low”(all the way to the right), operate blower speed control on
“Low”.
- Combustion air control greater than “Low”, operate blower speed control at desired setting
To turn OFF rotate the knob counterclockwise past the “click”

The replace chimney must be suitable for wood burning use. Check for creosote build up or other obstruc-
tions, especially if it has not been in use for some time.
The existing replace damper is to be locked open or removed completely. Have the chimney cleaned to pre-
vent odours and possible res.
WARNING: Do not remove bricks or mortar from your existing replace.
Exception: Masonry or steel, including the damper plate, may be removed from the smoke shelf and adja-
cent damper frame if necessary to accommodate a chimney liner, provided that their removal will not weaken
the structure of the replace and chimney, and will not reduce protection for combustible materials to less
than that required by the National Building Code.
Figure7:Fireplace specs.

Full Flue Liner - (Required in Canada)
A listed stainless steel rigid or exible liner extends
from the Insert ue collar to the top of the chimney.
In Canada, this Fireplace Insert must be installed
with a continuos chimney liner of 6 inch diameter
extending from the Fireplace Insert to the top of the
chimney. The chimney liner must conform to the
class 3 requirements of CAN/ULC-B365, Standard for
Lining Systems for Existing Masonry or Factory-Built
Chimneys and Vents, or CAN/ULC-S640, Standard
for Lining Systems for New Masonry Chimneys.
1) Measure the chimney height from the top of
the existing ue to the oor of the hearth. This will
allow extra length of liner for ashing and rain cap.
2) Feed the stainless steel liner from top of the
chimney, through the damper area and into the re-
place cavity.
3) Attach a stove connector to the bottom of the
liner, as per the instructions provided with the chim-
ney liner.
4) Push the Insert into position inside the re-
place and attach the connector to the stove collar
and secure with screws. Use the rear adjusting legs
to level the Insert.
5) Measure, trim and shape a top ashing to
t the existing chimney ue. Plan for a 1” to 1-1/2”
overlap on each side. Place ashing over top of the
liner and seat rmly against the tile. Screw ashing
collar to liner. Caulk gap around ashing with RTV
silicone.
6) Attach a rain cap to the end of the liner. A
storm collar may be used if desired.

The Insert must be installed in accordance with local and or national building codes. The two methods of ue
connection that are acceptable in most areas are shown on page 15 and 16.
A metal tag is provided and is to be fastened to the back wall of the replace, if the replace has been modi-
ed to accommodate the insert.
Pacic Energy highly recommends the use of a full liner as the safest installation and providing optimum per-
formance. When connected to a full liner, the Insert is able to draft correctly and will help prevent problems
such as difcult start-ups and smoking out the door.
Consult your local Dealer about codes and installation.

Into a Factory Built Fireplace
Your Insert may be installed into a factory built replace (size permitting) with the following requirements:
1) Inspect your replace for damage or other physical defects. The replace must be in good working
condition. If in doubt about its condition, seek professional advice. Check for creosote build up or other
obstructions inside the chimney, especially if it has not been in use for some time. Before installing, clean
your chimney system thoroughly.
2) A full stainless steel rigid or exible ue liner meeting type HT requirements (2100°F) per 1777 (U.S.) or
ULC S635 (Canada) must be used for both safety and performance. The liner must be securely attached to
the Insert ue collar and the chimney top.
3) The surround must be sealed to the replace front or the damper area around the chimney liner must
be sealed to prevent room air entering the chimney cavity of the replace.
4) The air ow within and around the replace must not be altered by the installation of the Insert (i.e. no
blockage of louvers or cooling air inlet or outlet ports). This includes the circulating air chambers in a steel
replace or metal heat circulator.
5) Alteration of the replace in any manner is not permitted with the following exceptions:
a: external trim pieces which do not affect the operation of the replace may be removed and stored
on or within the replace for re-assembly if the Insert is removed.
b: the chimney damper may be removed to install the liner.

Blower Maintenance / Removal
The blower requires annual cleaning to remove buildup on the blades. More frequent cleaning may be
required if room conditions are dusty or you have pets. THe cleaning of the Blower can be done easily by the
homeowner but we recommend having this done by a qualied service technician who can inspect the entire
unit at the same time.
To get access to the blower follow step 1 then gently vacuum any dust and hair from the blower inlets and
motor.
