Introduction
SAVE THIS INSTRUCTION MANUAL FOR FUTURE REFERENCE
This manual describes the installation and operation of the True North TN 40 Pellet Stove.
PLEASE READ THIS ENTIRE OWNER’S MANUAL BEFORE INSTALLING OR OPERATING YOUR PELLET
STOVE.
Operation
For proper and safe operation, the Door, Ash Drawer 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, Ash Pan and Hopper and replace when necessary.
Cleaning
The unit and its venting will require routine Maintenance and Cleaning. There will be some build up of y
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 signicant layer of creosote has accumulated,(3mm or more)it should
be removed to reduce the risk of a chimney re. Venting should be cleaned annually or every two tons of
pellets used.
Caution
The appliance, ue gas connector and the chimney ue require regular cleaning. Check them for blockage
prior to re-lighting after a prolonged shut down period.
Smoke and CO Detectors
Since there are always several potential sources of re in any home, we recommend installing smoke
detectors. We also recommend a CO detector be installed within the same room as the stove, this may be a
requirements of your local re code. Check with your local building/re department for requirements in your
area.
Optional Thermostat
This stove can be operated manually or with an optional low voltage wall thermostat (not provided).
Electrical Generator Operation
Your True North TN40 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.
If you have any questions with regards to your stove or the information contained in this manual, please
contact your local dealer for further clarication 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 regards to your local building codes and
installation restrictions.
It is strongly recommended that the stove be serviced annually by a trained professional.

dren, 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 uid, or similar liquids to start or
“freshen up” a re 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 ue damper in the exhaust venting
system of this unit. Do not connect this unit to a chimney ue serving another appliance.
Warning
Never place furniture, wood, paper, drapes or other combustible materials within 48” (122cm) of the front of
the unit, 6” (15cm) from each side, and 3” (8cm) from the back of the unit. Do not let children or pets touch
it when it is hot.
Chimney or Run Away Vent Fire
Call local re department. Extinguish the re in the burn pot liner with a cup of water and close the door.
Examine the ue pipes, chimney, attic, and roof of the house, to see if any part has become hot enough
to catch re. If necessary, spray with re 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 appliance with the glass front
removed, cracked, or broken. The stove uses ceramic glass. Replacement of the glass should be done by
a qualied service technician. Replacement glass must be purchased through a Pacic Energy Fireplace
Products dealer. Do not attempt to open the door and clean the glass while the unit is in operation or if
glass is hot.
KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN ASH PAN. A FIRE
IN THE ASH PAN MAY OCCUR.
Any grill, panel, or glass removed for service MUST be replaced prior to operating the stove. Failure to due
so may allow contact with shock or re hazards.
Caution:
When operating during extreme weather, if the unit exhibits dramatic changes in combustion stop using the
unit immediately.
Warning
This appliance is equipped with a three-prong (grounding) plug for your protection against shock
hazard 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 power cord under
or in front of appliance. The power supply cord must be routed to avoid contact with any of the hot or
sharp exterior surface areas of the stove.

65055.536-A_131016-32
TN40
Operating Instructions
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 be sealed and airtight. The ash pan
and viewing door must be locked securely for proper and safe operation of the pellet stove (See "Ash Pan
Removal and Cleaning: (Leg or Pedestal models)" on page 13).
Do not burn with insufcient combustion air. A periodic check is recommended to ensure proper combus-
tion 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 on the controls.
The combustion air inlet for this stove is drawn through a pipe inside the rear of the stove. Air can be pro-
vided 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 combus-
tion can easily be caused by many common household appliances which exhaust air from the home (such
as a furnace, heat pump, air conditioner, clothes dryer, exhaust fans, replaces, and other fuel burning
appliances).
Outside air: A 2”(51mm) id. non-combustible exible or rigid pipe can be attached between the stove’s air
intake and an outside duct to draw air from outside the house. This will greatly reduce the risk, but may not
eliminate the problem.
Pacic Energy Fireplace Products Ltd. accepts no liability for damages resulting from negative pressures
described here.
Outside Fresh Air is required for mobile home installations.
Negative Pressure Warning
This stove has been painted with a high-temperature metallic paint. It is dry to the touch, but completes the
curing process during the rst few times the stove is burned on high. Also, some parts of the appliance may
be lightly coated with machining oil. During the rst rings, the paint and oil may give off unpleasant odors.
Open the windows to ventilate the room.

Operating Instructions
Pellet Fuel Specifications
This stove is designed and EPA certied to burn premium wood pellet fuel. 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.
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 Specications;
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 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 burn-
ing process]. If the Burn Pot Liner holes do become blocked, remove the liner (when the unit is cold) and
clean/scrape the clinkers out. (See "Burn-Pot and Liner Cleaning" on page 12).
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 Cord wood is Prohibited. Do not burn garbage, rubber, plastics or flammable fluids such
as gasoline, naphtha or engine oil.

5055.536-A_131016-32 TN40
Operating Instructions
Note: when the stove is plugged into power for the rst time the combustion blower will come on and run
for 10 minutes, this is the same function as after a power failure.
Filling the Hopper
The hopper can be accessed by lifting the top of the stove. The hopper will hold up to 80 pounds (36 Kg) of
pellets. Check for any foreign objects in the hopper before lling with pellets.
Opening the Door
Rotate the door handle clockwise to the horizontal position and slowly pull 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. (See
"Burn-Pot and Liner Cleaning" on page 12). Check to see that the Burn Pot Liner is seated correctly and
pressed back against the Ignitor Tube for proper ignition and operation.
Lighting your Stove
Note: If this is the rst 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. Release the button once pellets begin to drop.
Push the ON/OFF button, on the control board, 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 rebox can be expected during light up. Once the ignition cycle is nished 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
ash 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 re damage.
General Operation
Use the HEAT LEVEL LOW and HIGH buttons to adjust the heat level to the desired setting.
Avoid over ring 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 an optimal burn on High or Low
Turning the Unit OFF
Normal - To turn the stove off, press the ON/OFF button. The Power light will turn orange and the control
panel lights will go out. The Auger will stop running but the fans will continue to operate until the exhaust
temperature drops to a safe temperature and the control board completes the shut down cycle.
Operation

10 5055.536-A_131016-32
TN40
Operating Instructions
Convection Blower Operation
Your TN40 stove comes equipped with a room air convection blower that extracts heat from the stove. After
the stove warms up, the fan will turn on automatically. The speed of the fan will automatically vary with the
burn rate of the stove. The fan will continue to operate after the Auger shuts off, until the stove has cooled
down.
Auger 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 OVER FIRE THE UNIT
- To decrease the Auger feed on High energy pellets, (if the low heat is still to 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 lowest heat settings due to a sudden change in pellet quality. By adjusting
the Combustion Blower Voltage you will effect the lowest four heat output combustion blower settings. To
adjust hold down the hidden button under the TH in "True North" on the controls and 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, a number of 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.

11
5055.536-A_131016-32 TN40
Operating Instructions
Thermostat Operation (Optional)
Once installed, the thermostat can control the operation of the stove. Use a low voltage/millivolt thermostat.
(See "Optional Thermostat Installation" on page 28) 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 power 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 (See "Before Lighting your stove" 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 set-
ting, 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 thermo-
stat), 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 air ow 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. (See "Setting the Damper" on page
27)
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 airow
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 airow through the liner.

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 perform-
ing 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 oor during the cleaning process.
Soot
Operation of the stove with insufcient combustion air will result in the formation of soot and/or creosote
which will collect on the glass, the heat exchanger, the exhaust vent system, and may stain the outside of
the house. Frequently check your stove and adjust as needed to ensure proper combustion (See "Setting
the Damper" on page 27).
Burn-Pot and Liner Cleaning
The Burn-Pot Liner has a number of holes in the bottom and sides that provide combustion air to the pel-
lets. The extreme temperatures in the Burn-Pot can cause the impurities in the pellets to form clinkers.
The liner should be inspected daily to ensure the holes are clear of any build up.
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 up on the Burn Pot Liner to remove. 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 up at the front of the pot pull it towards the front of the rebox
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 Burn Pot mounting
screws if required.

Open the Door and clean the glass using a soft cloth or paper towel and household non-abrasive glass
cleaner or wood stove window cleaner. DO NOT use abrasive cleaners.
Ash Pan Removal and Cleaning: (Leg or Pedestal models)
CAUTION: Do not remove the ash pan when the stove is operating or hot.
To remove the Ash Pan, Rotate the latch counter-clockwise to release the ash pan. Pull the Ash Pan up then
out from the stove. Safely dispose of ashes or Vacuum out the Ash Pan enclosure before inserting the Ash
Pan.
CAUTION: Disposal of Ashes - Ashes should be placed in a metal container with a tight tting lid. The
closed container should be placed on a non-combustible surface – well away from all combustible
materials, pending nal 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.
To close, push the Ash Pan in until the bottom catches and drops down. Make sure the Ash Pan is tight to
the face of the Ash Pan enclosure, then tighten the Latch.
WARNING: if the ash pan does not seal tightly to the stove, the stove can produce excess smoke and
emissions. Creosote may also form that will cover the inside of the unit and be expelled out of the
venting. If the Ash pan is left open enough the Firebox Vacuum Switch will open stopping the auger
and the stove will shut down.

Inspect Gaskets
Inspect the condition of the gaskets 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 as necessary. Inspect the die-cut
gaskets on the blowers when cleaning and replace if they become torn or damaged.
Cabinet Side Removal
Loosen or Remove the two screws holding the back of
the Cabinet Side to the chassis. Push the panel forward
to disengage the screws at the front. Installation is the
reverse.
Cleaning the Flue Gas Passages
Cleaning the ue gas passage 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 clean-
ing to be done more often. Clean this passage only when
the stove and ash are cold.
Cleaning the Firebox Passage
Remove the Burn-Pot and Liner as described in (See
"Burn-Pot and Liner Cleaning" on page 12), and use an
Ash Vacuum to remove the loose ash from the rebox.
• Remove the Upper Firebox Liner by pulling it forward. It will then drop down and can be pulled out
through the door opening
• Using penetrating oil and a ratchet with a 5/16” socket, remove a total of ve screws securing both
sides of the Firebox Liner to the rebox (Figure 5).
Using a 3/8" socket, remove the two screws
securing the center rebox liner section and
remove from rebox (Figure 6).
Using an ash vacuum, clean out all the ash in the
exhaust passages (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 passage is
clear of ash build-up, reinstall the Firebox Liners.

Pacific Energy Fireplace Products recommends having your stove inspected
and cleaned by a trained professional.
Cleaning the Vent Pipe
Soot and Fly-ash – Formation and Need for Removal: The products of combustion will contain small par-
ticles of y-ash and/or soot. The Fly-ash and/or soot will collect in the exhaust venting system and restrict
the ow of the ue gases. The exhaust venting system should be inspected at least once every year to
determine if cleaning is necessary. Sweep the pipe as needed. A tee and clean-out in the vent system at the
transition from horizontal to vertical will make this cleaning easier.
Cleaning the Exhaust/Combustion Blower
To clean the combustion blower, unplug the stove, remove the left cabinet side. Remove the four screws
(Figure 8) with a Phillips screwdriver. The motor can now be pulled from the fan housing. The blower cool-
ing fan and main blade can be vacuumed once the motor is removed. Before reinstalling, vacuum out the
blower housing and the ue gas passages leading to and from the combustion blower. Clean the inner sur-
face of the Proof of Fire Switch located on the combustion fan housing. 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 ange, tighten the
four screws with a Phillips screwdriver.

Installation
Installation Options
• Residential or Manufactured/Mobile Home
• Maximum 36" deep Alcove
• Vertical and Horizontal Vent (See "Venting" on page 24).
• Thermostat or manual operation
• Outside Air Compatible
Selecting a Location
Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or
roofs, and all construction meets local building codes. It is recommended that the unit be secured into its
position in order to avoid any displacement. This appliance must be installed on a oor with an adequate
load bearing capacity, if existing construction doesn’t meet load capacity, suitable measures (e.g. load dis-
tributing plate) must be taken to achieve it.
Due to high temperatures, the stove should be located out of trafc areas and away from furniture and
draperies.
The layout of your house and the location of the Pellet Stove will determine how efcient it is at heating the
intended area. Pellet Stoves use mainly air circulation to disperse their heat, therefore a central location with
good airow works best. Try to locate the heater in the area you want heated.
Consider the following things when selecting a location:
• Use of an existing approved Chimney
• Location of Vent Termination
• Aesthetic Considerations
• Interference with House Framing, Plumbing and Wiring
• Floor Protection
• Room Trafc Patterns
• Proximity to Combustibles
• Location of Air for Combustion
• Electrical Outlet
• Pellet Fuel Storage
Caution:
DO NOT CONNECT TO OR USE IN CONJUNCTION WITH ANY AIR DISTRIBUTION DUCT WORK. THIS UNIT IS
NOT APPROVED FOR SUCH INSTALLATIONS.

Connecting the True North TN40 stove to outside combustion air is optional, except in mobile home
installations and when required by local building codes. The stove’s internal air intake will accept 2”(51mm)
ID non combustible pipe to accommodate outside air installations. The air intake on the exterior of the home
should always be located substantially below the ue termination and terminate with a screen cover to keep
out weather and pests.
Outside air can be taken from a well ventilated crawl space. However, outside air must not be drawn from
an enclosed space (garage, unventilated crawl space).
Maximum recommended length is 10ft. (3m). If a longer run is needed increase the intake supply tube to 3"
(75mm)
