FLOOR PROTECTION
This heater must have a non-combustible oor protector (ember protection) installed beneath it if the oor is
of combustible material. If a oor pad is used, it should be UL listed or equal. The oor pad or non-combustible
surface should be large enough to cover at least the area under the product and 6 in. (152 mm) beyond the
front and beyond each side of the fuel loading and ash removal openings. Your heater will need a minimum 31”
x 38” oor protector. Floor protection must extend under and 2 in. (50.8mm) to each side of the chimney tee for
an interior vertical installation (see FIGURE 2).
Canadian Installations require a minimum of 450 mm [17.7”] beyond the front of the unit and 200mm [7.8”]
beyond each side of the unit. A Floor Protector of ¼ inch thick is recommended for this installation.
VENTING REQUIREMENTS
• Install vent at clearances specied by the vent manufacturer.
• Do not connect the pellet vent to a vent serving any other appliance or stove.
• Do not install a ue damper in the exhaust venting system of this unit.
The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove
and to local building codes. Do not use makeshift methods or compromise in the installation.
MAXIMUM VENTING DISTANCE
Installation MUST include at least 3-feet of vertical pipe outside the home. This will create some natural draft to
reduce the possibility of smoke or odor during appliance shutdown and keep exhaust from causing a nuisance
or hazard by exposing people or shrubs to high temperatures. The maximum recommend vertical venting height
is 12-feet for 3-inch type “PL” vent. Total length of horizontal vent must not exceed 4-feet. This could cause back
pressure. Use no more than 180 degrees of elbows (two 90-degree elbows, or two 45-degree and one 90-degree
elbow, etc.) to maintain adequate draft.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too
much draft may cause excessive temperatures in the appliance. Inadequate draft may cause backpufng into
the room and ‘plugging’ of the chimney. Inadequate draft will cause the appliance to leak smoke into the room
through appliance and chimney connector joints. An uncontrollable burn or excessive temperature indicates
excessive draft. Take into account the chimney’s location to insure it is not too close to neighbors or in a valley
which may cause unhealthy or nuisance conditions.
PELLET VENT TYPE
A UL listed 3-inch or 4-inch type “PL” pellet vent exhaust system must be used for installation and attached to the
pipe connector provided on the back of the stove (use a 3-inch to 4-inch adapter for 4-inch pipe). Connection
at back of stove must be sealed using Hi-Temp RTV. Use 4-inch vent if the vent height is over 12-feet or if the
installation is over 2,500 feet above sea level.
We recommend the use of Simpson Dura-Vent® or Metal-Fab® pipe (if you use other pipe, consult your local
building codes and/or building inspectors). Do not use Type-B Gas Vent pipe or galvanized pipe with this unit. The
pellet vent pipe is designed to disassemble for cleaning and should be checked several times during the burning
season. Pellet vent pipe is not furnished with the unit and must be purchased separately.
IMPORTANT! This unit is equipped with a negative draft system that pulls air through the burn pot and pushes
the exhaust out of the dwelling. If this unit is connected to a ue system other than the way explained in this
manual, it will not function properly.
6
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable collection of y ash and to permit periodic cleaning
of the exhaust system. 90-degree elbows accumulate y ash and soot thereby reducing exhaust ow and
performance of the stove. Each elbow or tee reduces draft potential by 30% to 50%. All joints in the vent system
must be fastened by at least 3 screws, and all joints must be sealed with Hi-Temp RTV silicone sealant to be
airtight. The area where the vent pipe penetrates to the exterior of the home must be sealed with silicone or
other means to maintain the vapor barrier between the exterior and the interior of the home. Vent surfaces can
get hot enough to cause burns if touched by children. Non-combustible shielding or guards may be required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-enclosed area, such as; carport, garage, attic, crawl space,
under a sun deck or porch, narrow walkway, or any other location that can build up a concentration of fumes.
Termination in one of these areas can also lead to unpredictable pressure situations with the appliance, and
could result in improper performance and/or malfunction The termination must exhaust above the outside air
inlet elevation. The termination must not be located where it will become plugged by snow or other materials. Do
not terminate the venting into an existing steel or masonry chimney.
VENT TERMINATION CLEARANCES
A. Minimum 4-foot (1.22m) clearance below or
beside any door or window that opens.
B. Minimum 1-foot (0.3m) clearance above any
door or window that opens.
C. Minimum 3-foot (0.91m) clearance from any
adjacent building.
D. Minimum 7-foot (2.13m) clearance from any
grade when adjacent to public walkways.
E. Minimum 2-foot (0.61m) clearance above any
grass, plants, or other combustible materials.
F. Minimum 3-foot (0.91m) clearance from an
forced air intake of any appliance.
G. Minimum 2-foot (0.61m) clearance below
eves or overhang.

You have already made the important decision of choosing your U.S. Stove Pellet Burning Room Heater; now
your next step is to determine where to install your new pellet stove heater. To get the most efcient use of re-
circulated heat, you should consider a room that is centrally located within your home. Choose a room that is
large and open.
It is Extremely Important to maintain proper clearances from any combustible surfaces or materials in the room
where your heater will be located. You can nd proper clearance measurements in this manual and on the
rating label of your pellet stove.
The pellet stove can be vented through an exterior wall or into an existing masonry or metal chimney if “PL” or
“L” vent pipe is used throughout existing chimney. Venting can pass through the ceiling and roof if approved
pipe is used. Where passage through a wall, or partition of combustible construction is desired, the installation
must conform to CAN/CSA-B365.
DO NOT OBTAIN COMBUSTION AIR FROM THE ATTIC, GARAGE OR ANY OTHER UNVENTILATED AREA. YOU MAY
OBTAIN COMBUSTION AIR FROM A VENTILATED CRAWL SPACE.
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 HEATER, FURNACE OR APPLIANCE.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
ONLY USE APPROVED MATERIAL FOR INSTALLATION, FAILURE TO DO SO MAY RESULT IN PROPERTY DAMAGE,
BODILY INJURY, OR EVEN DEATH.
This appliance is certied for use with listed 3 inch or 4 inch “PL” or “L” pellet venting products. The use of other
components other than stated herein could cause bodily harm, heater damage, and void your warranty.
HORIZONTAL EXHAUST VENT INSTALLATION
1. Locate your pellet stove in a location which meets the requirements of this manual, but in an area where it
does not interfere with the house framing, wiring, etc.
2. Install a non-combustible hearth pad underneath the pellet stove. This pad should extend at least 6” (152mm)
in front of the unit.
3. Place the pellet stove approximately 15” (381mm) away from the interior wall.
4. Locate the center of the exhaust pipe of your unit. This point should then be extended to the interior wall of
your house. Once you have located the center point, on the interior wall, cut a 7” (175mm) diameter hole
through the wall.
5. The next step is to install the wall thimble, refer to the instructions which come with the wall thimble for this
step.
6. Install the appropriate length of exhaust vent pipe into the wall thimble. See steps 11 and 12 when determining
the correct length of exhaust vent to use.
7. Outside Fresh Air is Mandatory when installing this pellet stove room heater in airtight homes and mobile
homes. Be sure that the outside air vent has an approved cap on it to prevent rodents from entering. Be sure
to install in location that won’t become blocked with snow, etc.
8. The air intake pipe is equipped with a buttery valve that is preset to maximum air intake. For optimum
operating efciency you may calibrate the buttery valve to provide less intake air. Caution: Too much
restriction on the intake air will cause dirtier burn, therefore, will require more frequent cleaning.
9. Connect the exhaust vent pipe to the exhaust outlet of your pellet stove.
10. Secure all vent joint connections with 3 screws. Seal the exhaust vent joint connections with high temperature
silicone sealant.
11. Push the unit straight back to the interior wall, being sure to maintain the minimum clearances to combustibles
6” (152mm) to the back of the unit. Seal the annular space of the wall thimble and around the vent pipe
with high temperature silicone sealant.
12. The exhaust vent pipe must extend at least 12” (300mm) out past the exterior wall. Seal the annular space of
the wall thimble and around the vent pipe with high temperature silicone sealant.
13. Install an approved horizontal termination cap or if necessary install a 90° elbow and appropriate length of
vertical venting. An approved vertical vent cap is recommended.
8
TYPICAL THROUGH THE WALL INSTALLATION
THROUGH THE WALL INSTALLATION (RECOMMENDED INSTALLATION)
Canadian installations must conform to CAN/CSA-B365. To vent the unit through the wall, connect the pipe
adapter to the exhaust motor adapter. If the exhaust adapter is at least 18 in.(457mm) above ground level, a
straight section of pellet vent pipe can be used through the wall.
Your heater dealer should be able to provide you with a kit that will handle most of this installation, which
will include a wall thimble that will allow the proper clearance through a combustible wall. Once outside the
structure, a 3 in.(76mm) clearance should be maintained from the outside wall and a clean out tee should be
placed on the pipe with a 90-degree turn away from the house. At this point, a 3ft (0.91m) (minimum) section of
pipe should be added with a horizontal cap, which would complete the installation.
A support bracket should be placed just below the termination cap or one every 4ft (1.22m) to make the system
more stable. If you live in an area that has heavy snowfall, it is recommended that the installation be taller than 3ft
(0.91m) to get above the snowdrift line. This same installation can be used if your heater is below ground level by
simply adding the clean-out section and vertical pipe inside until ground level is reached. With this installation you
have to be aware of the snowdrift line, dead grass, and leaves. We recommend a 3ft (0.91m) minimum vertical
rise on the inside or outside of the house.
The “through the wall” installation is the least expensive and simplest installation. Never terminate the end vent
under a deck, in an alcove, under a window, or between two windows.
THROUGH THE ROOF/CEILING
INSTALLATION
When venting the heater through the ceiling,
the pipe is connected the same as through
the wall, except the clean-out tee is always
on the inside of the house, and a 3 in.(76mm)
adapter is added before the clean-out tee.
You must use the proper ceiling support
anges and roof ashing (supplied by the pipe
manufacturer; follow the pipe manufacturer’s
directions). It is important to note that if your
vertical run of pipe is more than 15ft (4.57m),
the pellet vent pipe size should be increased
to 4 in. (102mm) in diameter.
Do not exceed more than 4ft (1.22m) of pipe
on a horizontal run and use as few elbows as
possible. If an offset is required, it is better to
install 45-degree elbows rather than 90-degree
elbows.
9
OUTSIDE AIR SUPPLY (OPTIONAL, UNLESS INSTALLING IN A MOBILE HOME)
Depending on your location and home construction, outside air may be necessary for optimal performance.
Metal pipe (solid or exible) must be used for the outside air installation. PVC pipe is NOT approved and should
NEVER be used.
A wind shield over the termination of the outside air pipe or a 90-degree elbow or bend away from the prevailing
winds MUST be used when an outside air pipe is installed through the side of a building. The outside air termination
MUST be at least 1ft (0.305m) away from the exhaust system termination.
The outside air pipe on your heater is 2” (50.8mm) OD. The outside air connecting pipe must be at least 2”
(50.8mm) ID. The outside air connection used MUST NOT restrict the amount of air available to your heater. The
outside air connecting pipe must be as short and free of bends as possible, and it must t over, not inside, the
outside air connection to the heater.
NOTE: Dimensions from the oor to your stoves
inlet/exhaust pipes are approximate and may
vary depending on your installation.

kerosene, charcoal lighter uid, or similar liquids to start or “freshen up” a re in this stove. Keep all such
liquids well away from the stove while it is in use.
• HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN
BURNS.
This heater is designed to burn only PFI Premium grade pellets. This appliance can also burn pellets rated as
standard after May 16, 2015
DO NOT BURN:
Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.
PROPER FUEL
THIS STOVE IS APPROVED FOR BURNING PELLETIZED WOOD FUEL ONLY ! Factory-approved pellets are those 1/4”
or 5/16” in diameter and not over 1” long. Longer or thicker pellets sometimes bridge the auger ights, which
prevents proper pellet feed. Burning wood in forms other than pellets is not permitted. It will violate the building
codes for which the stove has been approved and will void all warranties. The design incorporates automatic
feed of the pellet fuel into the re at a carefully prescribed rate. Any additional fuel introduced by hand will not
increase heat output but may seriously impair the stoves performance by generating considerable smoke. Do
not burn wet pellets. The stove’s performance depends heavily on the quality of your pellet fuel. Avoid pellet
brands that display these characteristics:
1. Excess Fines – “Fines” is a term describing crushed pellets or loose material that looks like sawdust or sand.
Pellets can be screened before being placed in hopper to remove most nes.
2. Binders – Some pellets are produced with materials to hold the together, or “bind” them.
3. High ash content – Poor quality pellets will often create smoke and dirty glass. They will create a need for
more frequent maintenance. You will have to empty the burn pot plus vacuum the entire system more often.
Poor quality pellets could damage the auger. We cannot accept responsibility for damage due to poor
quality pellet.
PRE-START-UP CHECK
Remove burn pot, making sure it is clean and none of the air holes are plugged. Clean the rebox, and then
reinstall burn pot. Clean door glass if necessary (a dry cloth or paper towel is usually sufcient). Never use abrasive
cleaners on the glass or door. Check fuel in the hopper, and rell if necessary.
BUILDING A FIRE
Never use a grate or other means of supporting the fuel. Use only the burn pot supplied with this heater.
Hopper lid must be closed in order for the unit to feed pellets.
During the start-up period:
1. Make sure burn pot is free of pellets.
2. DO NOT open the viewing door.
3. DO NOT open the damper, the damper needs to be closed during start up.
4. DO NOT add pellets to the burn pot by hand.
NOTE: During the rst few res, your stove will emit an odor as the high temperature paint cures or becomes
seasoned to the metal. Maintaining smaller res will minimize this. Avoid placing items on stove top during this
period because paint could be affected.
1. Garbage;
2. Lawn clippings or yard waste;
3. Materials containing rubber, including tires;
4. Materials containing plastic;
5. Waste petroleum products, paints or paint thinners,
or asphalt products;
6. Materials containing asbestos;
7. Construction or demolition debris;
8. Railroad ties or pressure-treated wood;
9. Manure or animal remains;
10. Salt water driftwood or other previously salt water
saturated materials;
11. Unseasoned wood; or
12. Paper products, cardboard, plywood, or
particleboard. 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.
Operation
12
THE FIRESTARTER
1. Fill hopper and clean burn pot.
2. Press “On/Off” button. Make sure green light comes on.
3. The damper should be completely closed or open no more than ¼ of the way during start-up. This will vary
depending on your installation and elevation. Once re is established adjust for desired ame increasing the
amount the damper is open as the heat setting is increased. (See “DAMPER CONTROL”)
4. Adjust feed rate to desired setting by pressing “Heat Level Advance” button.
If re doesn’t start in 12 minutes, press “On/Off”, wait a few minutes, clear the burn pot, and start procedure
again.
DAMPER CONTROL
The damper control lever is located on the back of the stove on the lower left side. The dampener adjusts
the combustion air. This control is necessary due to the varied burn characteristics of individual installations,
different pellet brands and pellet feed rates. It allows you to improve the efciency of your stove. Providing
correct combustion air will reduce the frequency of cleaning your glass door and prevent the rapid buildup of
creosote inside your stove and chimney.
You should adjust the damper based on the re’s appearance. A low, reddish, dirty re can be improved by
turning the dampener slightly to the right. A “blow torch” re can be improved by turning the dampener to the
left a little bit.
As a general rule, on lower feed rate settings, the damper should be farther to the left closing it off. On higher
feed rates, the damper should be open more by having it set more towards the right. Through trial and error, you
will nd the best setting. Consult your dealer if you need help.
NOTE: On heat range “1”, damper should be either completely closed or open no more than a ¼ of the way. If
damper is open to far, it can cause the re to go out.
OPENING DOOR
If the door is opened while the stove is in operation it must be closed within 30 seconds or the stove will shut
down. If the stove shuts down push the “On/Off” button to re-start your stove. The stove will have to fully shut
down and turn off before you will be able to restart the stove.
ROOM AIR FAN
When starting your stove the Room Air Fan will not come on until the stove’s heat exchanger warms up. This
usually takes about 10 minutes from start-up.
IF STOVE RUNS OUT OF PELLETS
The re goes out and the auger motor and blowers will run until the stove cools. This will take 30 minutes or longer
depending on the heat remaining in the appliance. After the stove components stop running all lights on the
display will go out and the two digit display will begin ashing “E3”
REFUELING
• The hopper and stove top will be hot during operation; therefore, you should always use some type of hand
protection when refueling your stove.
• Never place your hand near the auger while the stove is in operation.
We recommend that you not let the hopper drop below ¼ full.
KEEP HOPPER LID CLOSED AT ALL TIMES EXCEPT WHEN REFILLING.
DO NOT OVERFILL HOPPER.
SHUTDOWN PROCEDURE
Turning your stove off is a matter of pressing the “POWER” button on the display board. The green light will turn
back to red when the “POWER” button is pushed. The auger motor will stop, and the blowers will continue to
operate until the internal rebox temperatures have fallen to a preset level.
WARNING: Never shut down this unit by unplugging it from the power source.
13
1. Your stove is equipped with a high temperature thermodisc. This unit has a manual reset thermodisc. This
safety switch has two functions.
A. To recognize an overheat situation in the stove and shut down the fuel feed or auger system.
B. In case of a malfunctioning convection blower, the high-temperature thermodisc will automatically
shut down the auger, preventing the stove from overheating.
NOTE: On some units, once tripped, like a circuit breaker, the reset button will have to be pushed before restarting
your stove. On other units the thermodisc has no reset button and will reset itself once the stove has cooled. The
manufacturer recommends that you call your dealer if this occurs as this may indicate a more serious problem.
A service call may be required.
2. If the combustion blower fails, an air pressure switch will automatically shut down the auger.
NOTE: Opening the stove door for more than 30 seconds during operation will cause enough pressure change to
activate the air switch, shutting the fuel feed off. The stove will shut down and show “E2” on the two digit display.
The stove has to fully shut down before restarting.
TAMPER 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 operating
instructions in this manual.
VISIBLE SMOKE
The amount of visible smoke being produced can be an effective method of determining how efciently the
combustion process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture
leaving your stove. Learn to adjust the air settings of your specic unit to produce the smallest amount of visible
smoke. Wood that has not been seasoned properly and has a high wood moisture content will produce excess
visible smoke and burn poorly.
• Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.
• Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any
inspection, cleaning, or maintenance work.
• Never perform any inspections, cleaning, or maintenance on a hot stove.
• Do not operate stove with broken glass, leakage of ue gas may result.
• Attempts to achieve heat output rates that exceed heater design specications can result in permanent
damage to the heater.
EXHAUST SYSTEM
Creosote Formation – When any 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 or a
newly started re or from a slow-burning re. As a result, creosote residue accumulates on the ue lining. When
ignited, this creosote makes an extremely hot re, which may damage the chimney or even destroy the house.
Despite their high efciency, pellet stoves can accumulate creosote under certain conditions.
Fly Ash – This accumulates in the horizontal portion of an exhaust run. Though non-combustible, it may impede
the normal exhaust ow. It should therefore be periodically removed.
Inspection and Removal – The chimney connector and chimney should be inspected by a qualied person
annually or per ton of pellets to determine if a creosote or y ash build-up has occurred. If creosote has accumulated,
it should be removed to reduce the risk of a chimney re. Inspect the system at the stove connection and at the
chimney top. Cooler surfaces tend to build creosote deposits quicker, so it is important to check the chimney
from the top as well as from the bottom. The creosote should be removed with a brush specically designed for
the type of chimney in use. A qualied chimney sweep can perform this service. It is also recommended that
before each heating season the entire system be professionally inspected, cleaned and, if necessary, repaired.
To clean the chimney, disconnect the vent from the stove.
Maintenance
14
WARNING: FAILURE TO PROPERLY MAINTENANCE THE CLEAN OUTS WILL
RESULT IN POOR PERFORMANCE OF THIS STOVE.
WARNING: Do not attempt to operate the heat exchange tube cleaner while the pellet stove is in operation
or cooling down; wait until pellet stove has cooled completely before performing this procedure.
INTERIOR CHAMBERS
• Burn Pot: Periodically remove and clean the burn pot and the area inside the burn pot housing. In particular,
it is advisable to clean out the holes in the burn pot to remove any build up that may prevent air from moving
through the burn pot freely.
• Heat Exchanger: There is a clean out plate on both sides of the heat exchanger that need to be removed to
clean y ash out of the heat exchanger. The clean outs are located inside the cabinet doors, on the lower
front corners of the heat exchanger. It is imperative that they be cleaned out at a minimum of once per
month. To access these clean outs, you must remove both side panels. The clean outs are secured to the
rebox with (2) 5/16” screws. Remove the clean outs and vacuum out any accumulated ash. This should be
done at least once per month or more frequently if large amounts of ash are noticed while cleaning or if the
stove does not seem to be burning properly
If a vacuum is used to clean your stove, we suggest using a vacuum designed for ash removal. Some regular
vacuum cleaner (i.e. shop vacs) may leak ash into the room.
DO NOT VACUUM HOT ASH
CLEANING
Heat Exchanger Tubes – Your Pellet Stove Room Heater is designed with a
built in heat exchanger tube cleaner. This should be used every 2 or 3 days to
remove ash build up on the heat exchanger tubes, which can reduce heat
transfer. The handle, for the heat exchanger tube cleaner, is located in front
of the vent tubes on front side of heater. Slide the rod front to back several
times to clean the tubes then follow the instructions for ash removal.
Periodically remove the clean outs on either side of the heat exchanger.
Clean out the ash, then follow the instructions for ash removal. Check the
gasket before replacing the clean out cover. If gasket is damaged new
gasket can be ordered. Alternatively, high temperature silicone can be used
to ensure a proper seal between the clean out cover and the stove body.

FANS – DANGER: RISK OF ELECTRIC SHOCK.
DISCONNECT POWER BEFORE SERVICING UNIT
Over time ash or dust may accumulate on the blades
of the circulation & exhaust fans. The fans should be
inspected, periodically, and if any accumulation
is present vacuumed clean as the ash or dust can
impede the fans performance. It is also possible
that creosote may accumulate in the exhaust fan
therefore, this must be brushed clean.
The exhaust fan can be found behind the left side
panel (facing the front of the heater), the circulation
fan can be found behind the right side panel. To
access the igniter, remove the air inlet tube and
cover (2 screws). The auger motor is located in the
center rear of the unit.
Note: When cleaning, take care not to damage the
fan blades.
CHECK AND CLEAN THE HOPPER
Check the hopper periodically to determine if there is any sawdust (nes) that is building up in the feed system
or pellets that are sticking to the hopper surface. Clean as needed.
DOOR AND GLASS GASKETS
Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have
frayed, broken, or compacted gaskets replaced by your authorized dealer. This unit’s door uses a 3/4” diameter
rope gasket.
BLOWER MOTORS
Clean the air holes on the motors of both the exhaust and distribution blowers annually. Remove the exhaust
blower from the exhaust duct and clean out the internal fan blades as part of your fall start-up.
PAINTED SURFACES
Painted surfaces may be wiped down with a damp cloth. If scratches appear, or you wish to renew your paint,
contact your authorized dealer to obtain a can of suitable high-temperature paint.
GLASS - CLEANING, REMOVAL AND REPLACEMENT OF BROKEN DOOR GLASS
Cleaning - We recommend using a high quality glass cleaner. Should a buildup of creosote or carbon accumulate,
you may wish to use 000 steel wool and water to clean the glass. DO NOT use abrasive cleaners. DO NOT perform
the cleaning while the glass is HOT. In the event you need to replace the glass, Do not attempt to operate the unit
with broken glass. Replacement glass may be purchased from your U.S. Stove Pellet Burning Room Heater Dealer.
If glass is broken, follow these removal procedures: Replacement glass must be 0.197” thick tempered ceramic
glass with a working service temperature of 1400 deg. F. Center Glass size: 10” x 10.67” Side glass size: 4” x 10.67”
1. Once the heater has cooled, remove the door from the heater.
2. Remove the rope gasket from the door followed by the eight(8) nuts holding the glass retainer in place.
3. While wearing gloves, carefully remove any loose pieces of glass from the door frame.
4. Replace the glass and gasket, making sure the gasket runs the full perimeter of the glass edge.
5. Re-install the retainer and eight nuts and rope gasket using high temperature silicone to adhere the gasket
to the door.
6. Never use substitute materials for the glass.
DO NOT abuse the door glass by striking, slamming or similar trauma. Do not operate the stove with the glass
removed, cracked or broken.

FALL START UP
Prior to starting the rst re of the heating season, check the outside area around the exhaust and air intake
systems for obstructions. Clean and remove any y ash from the exhaust venting system. Clean any screens on
the exhaust system and on the outside air intake pipe. Turn all of the controls on and make sure that they are
working properly. This is also a good time to give the entire stove a good cleaning throughout.
SPRING SHUTDOWN
After the last burn in the spring, remove any remaining pellets from the hopper and the auger feed system.
Scoop out the pellets and then run the auger until the hopper is empty and pellets stop owing (this can be done
by pressing the “ON” button with the viewing door open). Vacuum out the hopper. Thoroughly clean the burn
pot, and rebox. It may be desirable to spray the inside of the cleaned hopper with an aerosol silicone spray if
your stove is in a high humidity area. The exhaust system should be thoroughly cleaned.
MAINTENANCE SCHEDULE
Use the following as a guide under average use conditions.
Gaskets around door and door glass should be inspected and repaired or replaced when necessary.
ASH REMOVAL - FREESTANDING UNIT
Remove the ashes periodically to avoid unnecessary ash build up. Ash removal is as follows:
1. Let re burn out and allow unit cool to room temperature.
2. Clean the heat exchanger tubes (see Heat Exchanger Cleaning section) – Make sure Pellet Stove is at room
temperature before touching .
3. Open the ash pan door, remove the burn pot and empty into metal container.
4. Vacuum to remove ashes from the rebox.
5. BE SURE THAT ASHES ARE COOL TO THE TOUCH BEFORE VACUUMING. Some vacuum cleaners may leak ash
into the room. Your vacuum cleaner should have a special lter or bag to eliminate leakage.
6. Remove ash pan and dispose of ashes into metal container.
7. Reinstall ash pan.
8. Reinstall burn pot.

ASH REMOVAL - INSERT UNIT
1. Allow Heater to cool to room temperature
2. Lift the ash pan door up and pull out
3. Follow directions for free-standing unit.
DISPOSAL OF ASHES
Ashes should be placed in a steel metal container with
a tight tting lid. The closed container of ashes should
be placed on a non-combustible oor or on the ground
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. Do not place other waste in the same container.
SMOKE AND CO MONITORS
Burning wood naturally produces smoke and carbon
monoxide(CO) emissions. CO is a poisonous gas when exposed to elevated concentrations for extended periods
of time. While the modern combustion systems in heaters drastically reduce the amount of CO emitted out the
chimney, exposure to the gases in closed or conned areas can be dangerous. Make sure your stove gaskets and
chimney joints are in good working order and sealing properly to ensure unintended exposure. It is recommended
that you use both smoke and CO monitors in areas having the potential to generate CO.

When your stove acts out of the ordinary, the rst reaction is to call for help. This guide may save time and money
by enabling you to solve simple problems yourself. Problems encountered are often the result of only ve factors:
1) poor fuel; 2) poor operation or maintenance; 3) poor installation; 4) component failure; 5) factory defect. You
can usually solve those problems related to 1 and 2. Your dealer can solve problems relating to 3, 4 and 5.
For the sake of troubleshooting and using this guide to assist, you should look at your heat level setting to see
which light is ashing.
• Disconnect the power cord before performing any maintenance! NOTE: Turning the ON/OFF Switch to ”OFF”
does not disconnect all power to the electrical components of the stove.
• Never try to repair or replace any part of the stove unless instructions for doing so are given in this manual.
All other work should be done by a trained technician.
Display is Flashing “E1”
Possible Causes Possible Remedies: (Unplug stove rst when possible)
1. The convection blower is overheating and tripping
the internal temperature shutoff.
Clean any dust off of the windings and fan blade. If oiling the
blower does not help, the blower may be bad.
2. The stove is being left on the highest setting for
extended periods of time.
If operating the heater on the highest heat setting, the room
temperature could increase enough and lead to potential
overheating situations. If this happens try operating at a lower
heat setting.
3. Fuel other than wood pellets is being burned in the
stove.
This pellet stove is designed and tested to use wood pellets.
Check for signs of fuel other than wood pellets. No other
types of fuel have been approved for this pellet stove. If there
are signs of other types of fuel being used, stop using them
immediately.
4. Power surge or brown out situation.
A power surge, spike, or voltage drop could cause the high
limit switch to trip. Check to see if a surge protector is being
used on the stove. If not, recommend one to the customer.
5. High Limit Switch is malfunctioning. If the other items check out OK, replace the high limit switch.
Trouble Shooting Guide
Display is Flashing “E2”
Possible Causes Possible Remedies: (Unplug stove rst when possible)
1. Airow switch hose or stove attachment pipes for
hose are blocked.
Unhook air hose from the air switch and blow through it.
If air ows freely, the hose and tube are ne. If air will not
ow throw the hose, use a wire coat hanger to clear the
blockage.
2. The air inlet, burnpot, interior combustion air
chambers, combustion blower, or exhaust pipe are
blocked with ash or foreign material.
Follow all cleaning procedures in the maintenance section of
the owner’s manual.
3. The rebox is not properly sealed.
Make sure the door is closed and that the gasket is in good
shape.
4. Vent pipe is incorrectly installed.
Check to make sure vent pipe installation meets criteria in
owner’s manual.
5. The airow switch wire connections are bad.
Check the connectors that attach the gray wires to the air
switch.
6. Combustion blower failure.
With the stove on, check to see if the combustion blower is
running. If it is not, you will need to check for power going to
the combustion blower. It should be a full current. If there is
power, the blower is bad. If there is not, see #8.
7. Control board not sending power to combustion
blower.
If there is no current going to the combustion blower, check
all wire connections. If all wires are properly connected, you
have a bad control board.

Display is Flashing “E4”
Possible Causes Possible Remedies: (Unplug stove rst when possible)
1. The air inlet, burnpot, interior combustion air
chambers, combustion blower, or exhaust pipe are
blocked with ash or foreign material.
Follow all cleaning procedures in the maintenance section
of the owner’s manual.
2. The Proof of Fire (POF) thermodisc has came
unplugged
Check the (POF) thermodisc to see if the wires are
connected properly.
Display is Flashing “E3”
Possible Causes Possible Remedies: (Unplug stove rst when possible)
1. The hopper is out of pellets Rell the hopper.
2. The air dampener is too far open for a low feed setting
If on the low setting, you may need to close the dampener
all the way.
3. The burnpot holes are blocked. Remove the burnpot and thoroughly clean it.
4. The air inlet, the interior chambers, or exhaust system has
a partial blockage.
Follow all cleaning procedures in the maintenance section
of the owner's manual
5. The hopper safety switch has failed or hopper is open.
When operating the unit, be sure the hopper lid is closed so
that the hopper safety switch will activate. Check the wires
leading from the hopper safety switch to the control panel
and auger motor for secure connections. Use a continuity
tester to test the hopper safety switch; replace if necessary.
6. The auger shaft is jammed.
"Start by emptying the hopper. Then remove the auger
motor by removing the auger pin, then remove the two bolts
that hold the auger bracket to the auger tube. The auger
bracket will now be able to be removed form the auger
tube. Remove the two bolts on the side of the auger tube to
remove the lower bearing of the auger. Pull the auger out of
the tube to free the jam.
7. The auger motor has failed.
Remove the auger motor from the auger shaft and try to
run the unit. If the motor will turn the shaft is jammed on
something. If the motor will not turn, the motor is bad.
8. The Proof of Fire (POF) thermodisc has malfunctioned.
Temporarily bypass the POF thermodisc by disconnecting
the two wires and connecting them with a short piece of
wire. Then plug the stove back up. If the stove comes on and
works, you need to replace the POF thermodisc. This is for
testing only. DO NOT LEAVE THE THERMODISC BYPASSED. Your
blowers will never shut off and if the re went out the auger
will continue to feed pellets until the hopper is empty if you
leave the POF thermodisc bypassed.
9. The control board is not sending power to the POF
thermodisc or other auger system components.
There should be a 5-volt (approximately) current going to the
POF thermodisc after the stove has been on for 10 minutes.
8. Control board not sending power to air switch.
There should be a 5-volt current (approximately) going to the
air switch after the stove has been on for 30 seconds.
9. Air switch has failed.
To test the air switch, you will need to disconnect the air hose
from the body of the stove. With the other end still attached
to the air switch, very gently suck on the loose end of the hose
(you may want to remove the hose entirely off the stove and
the air switch rst and make sure it is clear). If you hear a click,
the air switch is working. BE CAREFUL TOO MUCH VACUUM
CAN DAMAGE THE AIR SWITCH.
