Introduction

SAVE THIS INSTRUCTION MANUAL FOR FUTURE REFERENCE This manual describes the installation and operation of the True North TN 40 Insert Pellet Stove. PLEASE READ THIS ENTIRE OWNER’S MANUAL BEFORE INSTALLING OR OPERATING YOUR PELLET STOVE. FAILURE TO FOLLOW INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE, BODILY INJURY, OR EVEN DEATH.

SAFETY NOTICE
If this stove is not properly installed, a house fire may result. For your safety, follow the installation instructions. Contact local building or fire officials about restrictions and installation inspection requirements in your area.

Operation
For proper and safe operation, the Door and Hopper Lid must be kept closed to prevent air leaks when the unit is in operation. The Auger will not operate when they are open. Check all gaskets on the Door and Hopper opening and replace them when necessary.

Cleaning
The unit and its venting will require routine Maintenance and Cleaning. There will be some build-up of fly ash with small amounts of creosote in the exhaust. This will vary due to the ash content of the fuel used and the operation of the stove. Inspect the venting periodically during the heating season to determine if a creosote buildup has occurred. If a significant layer of creosote has accumulated,(3mm or more)it should be removed to reduce the risk of a chimney fire. Venting should be cleaned annually or every two tons of pellets used.

Caution
The appliance, flue gas passages, and the chimney liner require regular cleaning. Check them for blockage before re-lighting after a prolonged shutdown period.

Smoke and CO Detectors
Since there are always several potential sources of fire in any home, we recommend installing smoke detectors. If your local code requires a smoke or CO detector to be installed within the same room, you must follow the requirements of your local code. Check with your local building/fire department for requirements in your area.

Optional Thermostat
This stove can be operated manually or with an optional low-voltage wall thermostat (not provided). If you have any questions with regard to your stove or any of the information contained in this manual, please contact your local dealer for further clarification and comments. To prevent the possibility of a fire, have the appliance installed by a professional. Ensure that the appliance is properly installed by adhering to the installation instructions. Your dealer will be happy to assist you in obtaining information with regard to your local building codes and installation restrictions. It is strongly recommended that the stove be serviced annually by a trained professional

Warning:
This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazards and should be plugged directly into a properly grounded three-prong, 120-volt, 60 Hz receptacle. Do not cut or remove the grounding prong from this plug. Do not route the power cord under or in front of the appliance. The power supply cord must be routed to avoid contact with any of the hot or sharp exterior surface areas of the stove.

Electrical Generator Operation
The use of a surge-protected power bar is recommended to ensure the stove’s electrical components are not damaged due to a surge in the electrical supply or lightning strike. Your True North TN40 Insert stove may be able to operate with power from a portable generator. However, the generator’s electrical regulator may not be compatible with the stove’s electronics. The higher the quality of the generator, (smoother the output sine wave) the greater the chance that it is compatible with the stove.

Warnings

Caution: Unit hot while in operation.
Parts of the appliance, especially the external radiant surfaces, will be hot to touch when in operation. Keep children, pets, clothing, and furniture away. Contact may cause skin burns. Children and adults should be alerted to the hazards of high surface temperatures and should stay away to avoid burns or clothing ignition. Young children should be carefully supervised when they are in the same room as the Pellet stove.

Flammable Liquids:
Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in the heater. Keep all such liquids well away from the heater while it is in use.

Caution
Do not connect to any air distribution duct or system. Do not install a flue damper in the exhaust venting system of this unit. Do not connect this unit to a chimney flue serving another appliance.

Warning

Never place furniture, wood, paper, drapes, or other combustible materials including Pellet Fuel within 48” (122cm) of the front of the unit, 12” (30cm) from each side, and within the fireplace enclosure.
Any grill, panel, or glass removed for service MUST be replaced pbeforeoperating the stove. Failure to do so may allow contact with shock or fire hazards.

Chimney or Run Away Vent Fire
Call the local fire department. Extinguish the fire in the burn pot liner with a cup of water and close the door. Examine the flue liner, chimney, attic, and roof of the house, to see if any part has become hot enough to catch fire. If necessary, spray with a fire extinguisher or water from the garden hose. IMPORTANT: Do not operate the stove again until you are certain the chimney and its lining have not been damaged.

Glass
Do not abuse the glass by striking or slamming the door. Do not operate the appliance with the glass front removed, cracked, or broken. The stove uses ceramic glass. Replacement of the glass should be done by a qualified service technician. Replacement glass must be purchased through a Pacific Energy Fireplace Products dealer. Do not attempt to open the door and clean the glass while the unit is in operation or if the glass is hot. Any panel or glass removed for service MUST be replaced before operating the stove. Failure to do so may allow contact with moving parts, shock, or fire hazards.

Caution
When operating during extreme weather, if the unit exhibits dramatic changes in combustion stop using the unit immediately. DO NOT OVERFIRE this appliance or attempt to operate it in a manner that it was not designed for. Operating this way may become a fire risk, cause damage to the unit, and void the warranty. Do not burn with insufficient combustion air, creosote may form in the unit and venting. This is a fire risk.

Negative Pressure Warning

This appliance has not been designed to be operated in a negatively pressurized room. Provide adequate air for combustion. The stove’s combustion system works with negative combustion chamber pressure and a slightly positive chimney pressure. It is very important to ensure that the exhaust system is sealed and airtight. The viewing door and Hopper Lid must be closed securely for proper and safe operation of the pellet stove Do not burn with insufficient combustion air. Creosote may be created or deposited inside your stove and chimney liner. A periodic check is recommended to ensure proper combustion air is admitted to the combustion chamber. Setting the proper combustion air (with the stove’s damper) is required after installation. Minor adjustments can also be made to the controls. The combustion air inlet for this stove is drawn through a pipe inside the rear of the stove. Air can be provided by the room the stove is installed in or by connection to outside of the house.

Room air: The room must be well-ventilated – In well-insulated/air-tight homes, a lack of air for combustion can be easily caused by many common household appliances that exhaust air from the home (such as a furnace, heat pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other fuel-burning appliances).
Outside air: A 2”(51mm) id. non-combustible flexible or rigid pipe can be attached between the stove’s air intake and the outside through the fireplace’s ash dump. This will greatly reduce the risk, but may not eliminate the problem if the home has a problem with extreme negative pressure.

Pacific Energy Fireplace Products Ltd. accepts no liability for damages resulting from the negative pressures described here.

Paint Curing
This stove has been painted with a high-temperature metallic paint. It is dry to the touch but completes the curing process during the first few times the stove is burned on high. Also, some parts of the appliance may be lightly coated with machining oil. During the first firings, the paint and oil may give off unpleasant odors. Open the windows to ventilate the room.

Pellet Fuel Specifications

This stove is designed and EPA-certified to burn Premium wood pellet fuel only. Burning any other fuel that is not approved for use with this appliance will void the appliance warranty.

Caution
It is important to select and use only fuel that is free of dirt or other impurities such as chemical binders or high salt content. “Dirty” fuel will adversely affect the operation and performance of the unit and will void the warranty. We recommend the use of pellets that meet or exceed the PFI standards. Ask your dealer for a recommended pellet type. Store fuels at least 48” (1.2 m) away from the pellet stove and in a cool dry location.

In The U.S.

Burn only pellets that have been graded by an EPA-approved organization. Pellet Fuels Institute, ENplus, or CANplus are approved organizations.

Minimum Fuel Specifications;
DENSITY: > 38lbs/cuft.
DIMENSIONS: < 1.5 in. with a diameter of .230 to .285 INORGANIC FINES (Ash Content): <1%CHLORIDES: <300ppm by weight.
ASH CONTENT: < 2%
TRACE METALS: < 100mg/kg
Contains no construction or demolition waste.

In Canada,

Use premium-grade pellets.

Max. feed rate is approx. 4.5 lbs/hour. Feed Rates can vary greatly depending on fuel type and quality Due to this, the stove may require adjustment to the damper and or the feed rate trim to achieve a satisfactory burn on low.

Ash:
The ash content of the fuel and the operation of your stove will directly determine the frequency of cleaning. The use of high-ash fuels may result in the stove needing to be cleaned daily. Pellets made from hardwoods generally produce more ash than those made from softwoods.

Clinkering:
[clinkers are minerals, silica (sand), or other impurities in the fuel that will form a hard mass during the burning process]. If the Burn Pot Liner holes do become blocked, remove the liner (when the unit is cold) and clean/scrape the clinkers out. Clean the holes with a small pointed object if required

BTU Content
BTU (heat value) content may range from just under 7,000 to almost 9,000 Btu/lb., depending upon species and region of the country and other variables. The use of Cordwood is Prohibited. Do not burn garbage, rubber, plastics, or flammable fluids such as gasoline, naphtha, or engine oil.

Controls

Control Panel: The following is a list of features on the control panel:

POWER light – Is red during start-up, switching to green when the stove is at operating temperature. The light will change to orange during the shutdown.
ON/OFF Button – Is pushed to start the stove, turn the auger off, and start the shut down sequence.
HEAT LEVEL Buttons – LOW is pushed to reduce the heat output. It is also used to reduce the values of the “trim” settings. HIGH is pushed to increase the heat output setting. It is also used to increase the values of the “trim” settings.
AUGER – The Auger will operate continuously while this button is pressed. It is also used with the Heat level buttons to trim the auger ON time pulses when the pellet quality/size requires more or less fuel to burn properly.
MAN-HI/LO-AUTO – Thermostat mode selector switch. The slide switch is used to select the desired thermostat mode. “Thermostat Operation:” on page 11
HEAT LEVEL INDICATORS – Show what heat output setting the unit is on. Low or #1 (bottom) and High or #5 (top). Also used to show fault codes and trim settings.
COMBUSTION TRIM – This button is hidden to prevent mistaken use of the feature. It is used with the Heat level buttons to trim the Combustion Blower voltage when the pellet quality/size requires more or less air to burn correctly. This feature should be used only after the firebox vacuum has been set.

Fault Codes:
If the stove shuts down unexpectedly, the following Heat Level indicator may be flashing.

Fault code, #3 light flashing: – Stove did not light / Fire went out / Stove went cold while in operation.
Fault code, #4 light flashing: – Hi limit switch is open / Stove overheated.

See troubleshooting section for causes and solutions.

Operation

Note: when the stove is plugged into power for the first time the combustion blower will come on and run for 8-10 minutes, this is the same function as after a power failure.

Filling the Hopper
The hopper can be accessed by sliding the stove top toward you. The hopper will hold up to 65 pounds (29 Kg) of pellets. Check for any foreign objects in the hopper before filling it with pellets. To fill the hopper, pellets will need to be pushed to the back during filling. The Hopper Lid is connected to a switch and must be completely closed before the Auger will operate.

Opening the Door
Rotate the door handle clockwise to the horizontal position and slowly pull it open. This will help prevent large amounts of ash from being sucked out as you open the door. To close the Door, reverse the steps.

Before Lighting your stove
Check the holes in the Burn Pot Liner to make sure they are clear. Remove any ash/clinkers if needed. “Burn-Pot and Liner Cleaning:” on page 13. Check to see that the BurnPot Liner is seated correctly and pressed back against the Ignitor Tube for proper ignition and operation.

Lighting your Stove:

Note: If this is the first time the stove has been started or the stove has run out of pellets, the auger will be empty and the Burn-Pot liner will need to be primed. To prime, place a handful of pellets into the middle of the liner. Or hold down the Auger button, this will cause the auger to run continuously while the button is held. On the control board, push the ON/OFF button. This will turn the POWER indicator light red and will begin a 15-minute lighting sequence. During the lighting sequence, the auger will pre- load the Burn-Pot liner with pellets, the igniter will light the pellets and once lit, the auger will resume feeding pellets. Some smoke inside the firebox can be expected during light-up. Once the ignition cycle is finished and the stove is lit, the POWER light will turn green. The stove will continue to burn at the desired level indicated by the HEAT LEVEL display.

Caution: Do not attempt to re-start the lighting sequence before it has run its course as the Burn-Pot will overload with pellets. If after 15 minutes the stove is not lit, the middle light of the HEAT LEVEL display will flash red. When cooled, safely empty the burn pot liner of any unburned pellets and re-start the stove.

WARNING: Never empty unburned pellets from the Burn-Pot into the pellet hopper. Pellets that appear to be cool may retain enough heat to ignite other pellets resulting in smoke or fire damage.

General Operation
Use the HEAT LEVEL LOW and HIGH buttons to adjust the heat level to the desired setting. Avoid over-firing the stove – do not hand-feed pellets to the appliance during operation. Due to different sizes and quality of the fuel, the stove may require adjustment to the damper and or the feed rate trim to achieve a satisfactory burn on low.

Turning the Unit OFF

Normal – To turn the stove off, press the ON/OFF button. The control panel lights will go out. The Auger will stop but the fans will continue to operate until the exhaust temperature drops and the control board completes the shutdown cycle.

Convection Blower Operation:
Your True North TN40 stove comes equipped with two convection blowers that extract heat from the stove. After the stove warms up, the fans will turn on. The speed of the fans varies with the burn rate of the stove. The fans will continue to extract heat after the stove shuts off and until it has cooled down.

Fuel Feed Trim
The controls allow you to adjust the Fuel Feed Trim slightly. [Factory setting is number 3] For low-quality pellets where the unit goes out during long periods on the Low Heat setting you can increase the amount of pellet feed across the whole heat range. Hold down the Auger button and the display will change to four lights on and one off, press the UP arrow for the Heat Output to increase the auger on time.

WARNING THIS WILL INCREASE THE FEED RATE FOR THE COMPLETE RANGE – BE CAUTIOUS – DO NOT OVERFIRE THE UNIT

To decrease the Auger feed on High energy pellets, (if the low heat is still too warm) decrease the fuel feed by holding down the Auger button and the display will change to four lights on and one-off, then press the Down arrow for the Heat Output to reduce the auger on time across the complete heat range Combustion Blower Trim.

WARNING: THIS SHOULD ONLY BE USED AFTER THE DAMPER HAS BEEN ADJUSTED AS PER THIS MANUAL AND AS A LAST RESORT. This feature should only be used if the unit is getting too much or too little combustion air when on the lowest heat settings due to a sudden change in pellet quality. By adjusting the Combustion Blower Voltage you will affect the lowest four heat output combustion blower settings. To adjust, hold down the hidden button across from the ON/OFF button and under the Heat Level buttons. Use the Heat Level buttons to adjust up or down the same way as the Auger Feed Trim. The factory setting is position number 3.

Normal Operating Sounds
As the True North TN40 stove is burning, several normal operational sounds may be heard. When the blowers come on, the sound of rushing air can be heard as well as some small creaks. The lower the burn rate the slower the fan operates. Pellets can be heard dropping into the Burn-Pot. Also, the motor turning the auger may be heard as it pulses on and off. Occasionally a cracking noise might be heard as the auger cuts a pellet in half.

Power Outage
If the stove loses electrical power and it is still hot when power returns, the stove will go into a start-up sequence and will continue to operate. If the power loss is long enough for the stove to cool, the exhaust blower will run for 10 minutes to purge any smoke. If the stove is connected to a thermostat in the “Auto mode”, the stove will not start the ignition sequence until the thermostat calls for heat again.

Thermostat Operation
Once installed, the thermostat can control the operation of the stove. Use a low voltage/millivolt thermostat. “Optional Thermostat installation” on page 22 for installation instructions.

Important: When connected to a thermostat, it is necessary to push the ON/OFF button for the initial burn, when the electrical flow to the stove is interrupted, or if the stove runs out of pellets and therefore shuts off with a fault code.

Manual Mode:
After the stove is burning “Opening the Door.” on page 9, the heat level setting controls the pellet feed rate and the stove’s heat output. Once set, the stove will continue to burn at this rate until the heat level is changed or the stove is shut off.

HI/LO Mode:
After the initial ignition sequence, when the thermostat calls for heat (the room temperature is less than the temperature set on the thermostat), the stove will burn at the heat level setting. The higher the setting, the quicker the room will heat up. Once the thermostat no longer calls for heat (the room is up to the desired temperature), the stove will drop down to burn at the lowest HEAT LEVEL setting. This cycle will continue until the stove is turned off or runs out of fuel.

AUTO Mode:
When the thermostat calls for heat (the room temperature is less than the temperature set on the thermostat), the stove will burn at the heat level setting. The higher the setting, the quicker the room will heat up. Once the thermostat no longer calls for heat (the room is up to the desired temperature), the stove will drop down to burn at the lowest HEAT LEVEL setting. The stove will continue to burn for 45 minutes at the lowest setting. If the thermostat does not call for heat again during that time, the stove will shut off. It will relight when the thermostat calls for heat. If, during that 45 min., the thermostat calls for heat again, the stove will again burn at the HEAT LEVEL setting until the thermostat no longer calls for heat.

Damper Adjustment
The Damper is used along with the Combustion Blower control to regulate airflow through the stove. THE DAMPER MUST BE SET AFTER INSTALLATION, DURING THE FIRST FIRING. This procedure should be done by a Qualified Installer or Service Technician. “Initial Set-up” on.

Because of the differences in pellet quality, the Damper may need to be adjusted from time to time. If the stove goes out continually on low, the unit may need to have the damper closed slightly for reduced airflow at the lower heat settings. If the stove continually builds up with ash/clinkers in the liner the damper may need to be opened slightly for more airflow through the liner.

Routine Checks and Maintenance

CAUTION: INSTALLATION AND REPAIR SHOULD ONLY BE PERFORMED BY A QUALIFIED SERVICE TECHNICIAN. DO NOT ATTEMPT TO SERVICE THE APPLIANCE YOURSELF.

IMPORTANT CAUTIONS
SHUT DOWN THE STOVE, UNPLUG THE POWER CORD, AND ENSURE THE APPLIANCE IS COLD BEFORE PERFORMING ANY MAINTENANCE WORK.

Some brands of pellets produce more ash and clinkers than others. Therefore the frequency of performing the following cleaning procedures depends to a great degree on the type of pellets burned.
Not cleaning this unit will cause it to burn poorly and may void your warranty.
A cleaning brush can be used to loosen any ash build-up before vacuuming.
CAUTION: DO NOT USE A STANDARD HOUSEHOLD VACUUM, USE AN ASH OR SHOP VACUUM. A FINE DUST FILTER MUST BE INSTALLED IN THE SHOP VACUUM, AS THE STANDARD FILTERS WILL LEAK THE FINE PARTICLES OF ASH INTO THE HOME. DEPENDING ON THE SYSTEM, USE CAUTION AS SOME DUST MAY STILL PASS THROUGH THE VACUUM. DO NOT VACUUM HOT ASH!
Using a drop cloth is recommended as some ash may spill onto the floor during the cleaning process.

Warning: Soot/Creosote:
Operation of the stove with insufficient combustion air will result in the formation of soot and/or creosote which will collect on the glass, the firebox, and the exhaust vent system, and may stain the outside of the house. This can lead to a fire and damage to the unit and its venting as well as your home. Frequently check your stove and adjust the combustion air as needed to ensure proper combustion “Initial Set-up” on page 23.

Cleaning Glass

CAUTION: Do not clean glass when hot. Do not open the front door when the stove is hot. Open the door and clean the glass using a soft cloth or paper towel and household glass cleaner or wood stove window cleaner. DO NOT use abrasive cleaners

Burn-Pot and Liner Cleaning
The Burn-Pot Liner has several holes in the bottom and sides that provide combustion air to the pellets. The extreme temperatures in the Burn-Pot can cause the impurities in the pellets to form ash and clinkers. The liner should be inspected daily to ensure the holes are clear The Burn Pot should be checked/cleaned out after burning about 5 – 10 bags of pellets. When the stove is cool, open the door then lift the Burn Pot Liner to remove it. Using a suitable vacuum clean out the Burn Pot. Or remove the Burn Pot by loosening the nuts on the bottom corners of the Burn Pot and sliding the Pot towards the back. Lift at the front of the pot and pull it towards the front of the firebox to remove it from the tubes. Empty the ash from the Burn-Pot and Liner. Scrape the bottom of the pot with a scraper to remove all ash and clinkers from these surfaces if needed. Make sure all the holes in the Burn Pot Liner are open. Clean/scrape any hard clinkers out. Clean the holes with a small pointed object if required Reinstall the burn pot into the stove by reversing the removal procedure, then place the burn pot Liner back into the burn pot, ensuring that the Ignitor hole is towards the back of the stove. Push the Burn Pot Liner back in the Burn Pot against the ignitor tube to create a seal for the ignitor. Tighten the Burn Pot mounting screws.

Ash Removal and Cleaning:

CAUTION: Do not remove ashes when the stove is operating or hot. Gently brush ashes into the bottom of the firebox. Remove the ashes with an ash or shop vacuum. DO NOT USE A STANDARD HOUSEHOLD VACUUM, use an Ash or shop-style vacuum with a fine dust filter installed.
CAUTION: Disposal of Ashes – Ashes should be placed in a metal container with a tight-fitting lid. The closed container should be placed on a non-combustible surface – 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 been thoroughly cooled.

Inspect Gaskets
Inspect the condition of the rope gasket around the door, window, and ash pan, periodically. If the gasket becomes loose or falls off, is excessively frayed, or has a gap in it, replace it as necessary. Inspect the die-cut gaskets on the blowers when cleaning and replace them if they become torn or damaged.

Surround and cabinet-side removal

Unplug the stove.
Lift the complete surround up slightly to disengage the mounting tabs and carefully pull towards you about 3″(76mm).
Disconnect the ribbon cable from the back of the control panel. Remove the surround and place it out of the way.

Cleaning the Flue Gas Passages
Cleaning the flue gas passages should be done at least once a year or every one to two tons of pellets used. (50-100 bags) Burning high ash pellets may require this cleaning to be done more often. Clean this passage only when the stove and ash are cold. Remove the Burn-Pot and Liner as per the previous cleaning section, and use an ash or shop vacuum to remove the loose ash from the firebox. Remove the Upper Firebox Liner Panel by lifting and pulling it forward. Swing the back edge down once it clears the Firebox Liner. Continue down until the Top Panel has disengaged from the front mounting pins. It will then come down and can be pulled through the door opening.

We recommended you use a little penetrating oil on the screws to ease in removal

Using a ratchet with a 5/16” socket, remove the 5 screws securing the Firebox Liner to the firebox. (Figure #5) Remove the firebox liner.

Using an ash or shop vacuum, clean out all the ash in the exhaust passages. (See Figure 7) Don’t forget to clean up around the heat exchanger by using the vacuum on the openings above the door opening. Once the flue passage is clear of ash buildup, reinstall the Firebox Liner.

Cleaning the Exhaust/Combustion Blower:
To clean the combustion blower, unplug the stove, and remove the surround and the left cabinet side. Remove the four screws (Figure 7) with a Philips screwdriver. The motor can now be pulled from the fan housing. The blower cooling fan and main blade can be vacuumed once the motor is removed. Before reinstalling, vacuum out the blower housing and the flue gas passages leading to and from the combustion blower. Clean the inner surface of the Proof of Fire Switch located on the combustion air channel. When reinstalling the motor, check the gasket between the motor and the fan housing, a new gasket may need to be installed if damaged. Place the motor back on the fan housing (motor down) and rotate clockwise to lock the flange, tighten the four screws with a Philips screwdriver.

Cleaning the Vent Pipe:
The products of combustion will contain small particles of fly ash and/or soot. The Flyash and/or soot will collect in the exhaust venting system and restrict the flow of the flue gases. The exhaust venting system should be inspected at least twice every year to determine if cleaning is necessary. Sweep the liner as needed. The insert is equipped with a clean-out tee in the exhaust system at the transition from horizontal to vertical making cleaning easier.

Pacific Energy Fireplace Products recommends having your stove inspected and cleaned by a trained professional.

Cleaning the Convection Blowers
Disconnect power to the stove. Remove the Surround Panel and Cabinet Sides. “Surround and Cabinet Side Removal” on. There is one blower on each side of the firebox.

A vacuum can be used to remove any dust accumulation on the blower’s blades or inside the blower ducts. Caution should be used not to damage the blower’s blades during cleaning. Vacuum around the motor.
Reverse the removal process to reinstall the Cabinet Sides and surround panel set.

DOOR GLASS – Replacement
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 the position for re-assembly. Remove all particles of glass. Be careful as they are very sharp. Install new glass complete with a glass gasket. Replace clamps and screws.

CAUTION

do not overtighten, tighten screws very carefully

Installation Options

Solid Fuel burning fireplace
Certified Wood Burning, Factory Built Fireplace
Thermostat or manual operation
Outside Air Compatible

Selecting a Location:
This appliance must be installed in a wood burning fireplace with an adequate load-bearing capacity, if existing construction doesn’t meet load capacity, suitable measures (e.g. load-distributing plate) must be taken to achieve it. Due to high temperatures, the stove should be located away from furniture and draperies. The layout of your house and the location of the Pellet Stove will determine how effective it is at heating the intended area. Pellet Stoves use mainly air circulation to disperse their heat, therefore a central location with good airflow will work the best. Try to locate the heater in the area you want heated.

Caution
DO NOT CONNECT TO OR USE IN CONJUNCTION WITH ANY AIR DISTRIBUTION DUCT WORK. THIS UNIT IS NOT APPROVED FOR SUCH INSTALLATIONS.

Fireplace Dimensions

The appliance must be installed on a non-combustible Masonry hearth extending the full width and depth under the heater (including the vent pipe), and must extend an additional 16″ (152mm) beyond the front of the fireplace opening. Additional Ember Protection, if required, must extend 6″ (150mm) in front of and beyond each side of the Firebox Viewing Door.

Clearances to Combustibles

Installation

Before you begin
Please read and carefully follow all of the installation and operating instructions found in this manual. Please pay special attention to the safety instructions provided in this manual. The services of a competent installer, certified by the Wood Energy Technical Program (WETT) in Canada, and Hearth Education Foundation (HEARTH) – in the U.S.A. (or equivalent) are strongly recommended. Contact your local building or fire official to obtain a permit and any information on installation restrictions and inspection requirements for your area. Check all local building and safety codes before installation. The installation instructions and appropriate code requirements must be followed exactly and without compromise. Familiarity with these requirements before installation is essential. Failure to follow these instructions will void the manufacturer’s warranty. Alterations to the stove are not allowed. Your Insert is approved to be installed into an approved masonry or factory- built zero-clearance fireplace. The masonry fireplace must be built according to the requirements of the Standard of Chimneys, Fireplaces, Vents and Solid Fuel Burning appliances, N.F.P.A. 211 (Latest Edition) or applicable National, Provincial, State or local codes. The installation shall conform to CAN/CSA-B365, Installation Code for Solid-Fuel-Burning Appliances and Equipment. The factory-built zero-clearance fireplace and its chimney must be listed per UL 127 or ULC S610 standards. Warning: Under no circumstances is this heater to be installed in a makeshift or “temporary” manner.

Venting

This heater is approved for venting with any UL 1777/ULC S635 or ULC S640 conforming 3″(76mm) or 4″(102mm) stainless steel chimney liner inside a masonry or approved wood burning chimney system. The stove’s flue collar is 3” in diameter and will require an increaser to use a 4″ liner. Maximum vent length is 45ft (13.5m)

Note: When installing this stove at altitudes over 4000 feet, we suggest the use of a 4”(102mm) pellet vent. The stove’s combustion blower pressurizes and pushes flue gases out the vent pipe. The vent pipe should be silicone and fastened with three screws to the stove’s starter pipe. If the liner does not have a locking system then all joints should be screwed together with three screws. If required, seal all joints with high-temperature silicone or aluminum tape. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT. DO NOT CONNECT THIS UNIT TO A CHIMNEY OR FLUE SERVING ANOTHER APPLIANCE.

Installing into a Masonry Fireplace

Inspect your fireplace for cracks, loose mortar, or other physical defects. If repairs are required, they should be completed before installing your insert.
The fireplace chimney must be suitable for wood burning use. Check for creosote build-up or other obstructions, especially if it has not been in use for some time.
The existing fireplace damper is to be locked open or removed completely. Have the chimney cleaned to prevent odors and possible fires.
A full Flue Liner is recommended for best performance.

WARNING: Do not remove bricks or mortar from your existing fireplace.

Exception: Masonry or steel, including the damper plate, may be removed from the smoke shelf and adjacent damper frame if necessary to accommodate a chimney liner, provided that their removal will not weaken the structure of the fireplace and chimney, and will not reduce protection for combustible materials to less than that required by the National Building Code. The Insert must be installed following local and or national building codes. The two methods of flue connection that are acceptable in most areas are shown.

A metal tag is provided and is to be fastened to the back wall of the fireplace if the fireplace has been modified to accommodate the insert.

Full Flue Liner – (Required in Canada)
A 3″(76mm) or 4″(102mm) chimney liner that conforms to 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. must be used and extended from the insert flue to the top of the chimney. Use a sealing plate at the top of the chimney and a rain cap on the liner.

Measure the chimney height from the top of the existing flue to the floor of the hearth. This will allow the extra length of liner for flashing and a rain cap.
Feed the stainless steel liner from the top of the chimney, through the damper area, and into the fireplace cavity.
Push the Insert inside the fireplace and attach the flex liner to the stove’s Ash Cleanout box adapter and secure it with screws. Push the unit close to its final position and use the rear adjusting legs to level the Insert.
Measure, trim and shape a top flashing to fit the existing chimney flue. Plan for a 1” to 1-1/2” overlap on each side. Place flashing over the top of the liner and seat firmly against the tile. Screw flashing collar to the liner. Caulk gap around flashing with RTV silicone.
Attach a rain cap to the end of the liner. A storm collar should be used.

Direct Flue Connection – (USA only)

Measure from the first chimney flue liner to the top of the Insert. Allow 12 inches extra length of the liner to insert into flue tile.
Feed the stainless steel liner through the damper area and into the first chimney flue tile. Seal around pthe ipe to the chimney.
Note: A clean-out door may be required under local codes when a direct flue connection is used. Consult local codes.
Push the Insert inside the fireplace and attach the flex liner to the stove’s Ash Cleanout box adapter and secure it with screws. Push the unit close to its final position and use the rear adjusting legs to level the Insert.

Into a Factory Built Fireplace
Your Insert may be installed into a factory-built fireplace (size permitting) with the following requirements:

Inspect your fireplace for damage or other physical defects. The fireplace 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.
A full stainless steel rigid or flexible flue liner meeting UL1777 (U.S.) or ULC S635 (Canada) must be used for both safety and performance. The liner must be securely attached to the Insert flue collar and the chimney top.
The surround must be sealed to the fireplace front or the damper area around the chimney liner must be sealed to prevent room air entering the chimney cavity of the fireplace.
The airflow within and around the fireplace 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 fireplace or metal heat circulator.
Alteration of the fireplace in any manner is not permitted with the following exceptions:
- external trim pieces that do not affect the operation of the fireplace may be removed and stored on or within the fireplace for re-assembly if the Insert is removed.
- the chimney damper may be removed to install the liner.

Outside Air

Connecting the True North TN40 stove to outside combustion air is optional, but recommended except when required by local building codes. The stove’s air intake will accept a 2”(51mm) ID noncombustible pipe to accommodate outside air installations. The air intake on the exterior of the home should always be located substantially below the flue termination and terminated with a screen cover to keep out weather and pests.

Outside air can be provided in several ways.

through an ash clean-out with a vented grill in place of the clean-out external cover.
A hole through the back of the fireplace.
Running a 2″ flex liner up the chimney system past the throat seal plate or the chchimneyop seal.

Optional Thermostat installation

Your Pellet Stove can be operated manually or by a thermostat. The stove comes from the factory in the manual mode. To operate in the two “Thermostat” modes, a low-voltage thermostat must be installed.

To install the thermostat:

Unplug the stove from the electrical outlet. Remove the Surround and right side Cabinet Side “Surround and Cabinet Side Removal” on page 14 and remove the 2 screws holding the main board to the side of the hopper.
Locate the double screw terminal wiring block at the top of the board (See Figure 15), loosen the two screws on the block. Insert one of the wires from the thermostat into one of the slots and tighten the screw. Repeat this process for the other thermostat wire.

“Thermostat Operation:” on page 19 for thermostat operation modes.

IMPORTANT NOTE: Follow the Thermostat manufacturer’s installation and set-up instructions. Failure to follow manufacturer instructions could result in a malfunction. Pay special attention to the thermostat location requirements. If the location requirements are not followed, the appliance may operate erratically or failure may occur.

Do not mount the thermostat where it may be affected by:

Radiant heat from the stove, sun, or other heat sources.
Drafts or dead spots behind doors or in corners.
Hot or cold air from ducts.

Initial Set-up

The stove’s damper needs to be set after installation, during the initial burn-in. This will optimize the stove’s performance based on the installation and reduce emissions. This should be done with a low-pressure digital vacuum gauge or Magnehelic.
Install the gauge using a sealed 1/8″ metal probe into the port located above or to the side of the ash pan door. Find the damper, located against the back of the Air Jacket. loosen the locking screw. Start the unit per the instructions. Check factory trim levels for both combustion blower and auger speed. They should be set to 3, middle position.”Controls” on page 8

After the unit has been running on high for 15-20 min. adjust the damper to achieve a reading of 0.10-0.12n.w.c.

To increase the vacuum in the firebox, pull the damper out towards the outside of the stove See”Figure 15: TN40 Damper.” and push it in to reduce the vacuum.

Next, turn the stove down to Heat Level 1 (LOW), wait 5 -10 minutes and take Vacuum readings. They should be 0.09″ to 0.11″ If not, adjust the Combustion Blower Trim up or down as needed.”Controls” on page 8 below

To adjust, the Combustion Blower Trim, hold down the hidden button under position “7” Figure 1: TN40 INSERT Control Panel” on page 8 and use the Heat Level buttons (up, and down arrows) to adjust up or down the same way as the Auger Feed Trim. The factory setting is position number 3. The light that is out indicates the setting. Tighten the Damper locking screw. Install the Surround.

Leveling Legs
The leveling legs provided can be used to stabilize the front or back of the unit on uneven or dropped surfaces. Thread the legs in from underneath the unit and adjust as needed when the unit is installed.

Install the bolts into the threaded inserts provided as needed.

Surround Assembly and Installation

Un-package the top panel and lay parts A, B, and C face down on a flat, non-marring surface. Fasten together with 1/4” x 1/2” bolts and nuts provided through holes at points “D” (Fig #17).
Lift the surround assembly to the upright position and make sure the front face is flat and even at the joints.
Move the assembled surround around the stove. Lower the surround carefully to avoid scratching the paint. Attach the ribbon cable to the Main circuit board.

Locate and engage the panel’s hooks into the slots located on the surround brackets. Push down to lock.
Locate the control panel wrapped in plastic in the back of the unit. Figure 18
Remove the plastic wrap from the control panel then remove the Keps nuts from the studs in the back of the surround. Engage the holes in the top and bottom of the control panel over the studs in the back of the surround and secure the control panel in place with the Keps nuts. Figure 19
Push the entire appliance back until the surrounding assembly is in contact with the fireplace structure.
