OUTSIDE AIR SUPPLY (OPTIONAL, UNLESS
INSTALLING IN A MOBILE HOME)
ATTENTION:
DO NOT VENT UNDER ANY PORCH, DECK,
AWNING, OR IN ANY SEMI ENCLOSED OR
ROOFED AREA. DOING SO MAY RESULT IN
UNPREDICTABLE AIRFLOW AT THE VENT
CAP UNDER CERTAIN CONDITIONS AND CAN
AFFECT THE PERFORMANCE OF YOUR STOVE,
AS WELL AS, OTHER UNFORESEEABLE ISSUES.
Depending on your location and home
construction, outside air may be necessary for
optimal performance. Your stove is approved to be
installed with an outside air intake (69FAK) which
is necessary for a mobile home. You can purchase
the 69FAK through your heater dealer. Installation
instructions are supplied with the air intake kit.
SECURING APPLIANCE TO THE FLOOR
Use the designated holes to secure the unit to the
oor.
MOBILE HOME
MOUNTING BOLT HOLES
WARNING! DO NOT INSTALL IN SLEEPING
ROOM.
CAUTION! THE STRUCTURAL INTEGRITY
OF THE MOBILE HOME FLOOR, WALL, AND
CEILING/ROOF MUST BE MAINTAINED.
WHEN INSTALLED IN A MOBILE HOME, THE
STOVE MUST BE GROUNDED DIRECTLY TO THE
STEEL CHASSIS AND BOLTED TO THE FLOOR.
In addition to the previously detailed installation
requirements, mobile home installations must
meet the following requirements:
• This stove must be securely fastened to the oor
of the mobile home through the two holes in the
rear of the stove using two, 1/4” lag bolts that are
long enough to go through both a hearth pad, if
used, and the oor of the home.
• The heater must be electrically grounded to the
steel chassis of the mobile home with 8 GA copper
wire using a serrated or star washer to penetrate
paint or protective coating to ensure grounding.
• Vent must be 3 or 4-inch “PL” Vent and must
extend a minimum or 36” (914 mm) above the roof
line of the mobile home and must be installed
using a certied ceiling re stop and rain cap.
• When moving your mobile home, all exterior
venting must be removed while the mobile home
is being relocated. After relocation, all venting
must be reinstalled and securely fastened.
• Outside air is mandatory for mobile home
installation. See Outside Air Supply section and
your dealer for purchasing.
• Check with your local building ofcials as other
codes may apply.
VENTING REQUIREMENTS
WARNING:
• INSTALL VENT AT CLEARANCES SPECIFIED
BY THE VENT MANUFACTURER.
• DO NOT CONNECT THE PELLET VENT TO A
VENT SERVING ANY OTHER APPLIANCE OR
STOVE.
• DO NOT INSTALL A FLUE 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.
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 FLUE SYSTEM OTHER THAN
THE WAY EXPLAINED IN THIS MANUAL, IT
WILL NOT FUNCTION PROPERLY.
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
INSTALLATION

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 backpufng 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 ensure it is not too close to
neighbors or in a valley which may cause unhealthy
or nuisance conditions.
PELLET VENT TYPE
A certied 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.
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. Noncombustible 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.

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.
H. Minimum 1-foot (0.3m) clearance horizontally
from combustible wall.
I. Must be a minimum of 3 foot (0.91m) above the
roof and 2 foot (0.61m) above the highest point
or the roof within 10 feet (3.05m).
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” (457
mm) 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” (76 mm)
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. We recommend Simpson Dura-Vent® or
Metal-Fab® kits.
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” (76 mm) 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 12ft (3.7m), the pellet vent
pipe size should be increased to 4” (102 mm) 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.

PANEL CONTROLS
The blowers and automatic fuel supply are
controlled from a panel on the top of this unit. The
control panel functions are a follows.
A. ON/OFF SWITCH (“POWER” BUTTON)
• When pushed, the stove will automatically ignite.
No other re starter is necessary. The igniter
will stay on for at least 10 and up to 12 minutes,
depending on when Proof of Fire is reached. The
re should start in approximately 5 minutes.
• The red light located above the “POWER” button
will turn green when pressed and remain green
until the stove is turned off.
• After pushing “POWER”, the auger motor is on for
3.5 minutes, off for 1 minute. During the remainder
of the start-up period, the auger motor operates
on the heat range “1” setting.
• During start up the heat level advance (Up and
Down keys) will change the heat range indicator
level accordingly, but there is no change in the
stoves operating conditions until start-up is
completed.
• During start-up ignition must occur within 12
minutes or the stove will error out and show E4.
• During the start-up phase, the Mode key does not
function.
B. LEVEL / TEMP ARROW BUTTONS
• These buttons when pushed will set the pellet
feed rate, hence the heat output or heat range of
your stove.
• The levels of heat output will incrementally
change on the bar graph starting from heat
range “1” to heat range “5”.
C. °C / °F Button
• The °C / °F button changes the two digit display
from degrees Celsius to degrees Fahrenheit.
D. MODE (M/T) BUTTON
• The Mode of the stove can be switched between
manual and controlled with a Thermostat.
Separate LEDs to the left of the two digit display
indicate the mode of operation – Manual or T-Stat.
The stove has to be in normal operation to be
switched from Manual to T-Stat mode.
• Manual mode operates according to the 5 set
levels of feed on the bar graph from heat range
“1” to heat range “5”.
T-Stat mode works as follows:
• The stove has a built in Thermostat into the
controls of the appliance. The temperature sensor
for the T-Stat is located on the back of the stove
behind the display board.
• Once the stove has gone into run mode the stove
can be switch into T-Stat mode.
• The Up and Down Level / Temp Arrow buttons are
used to change the desired set-point temperature.
Once the desired temperature is reached the two
digit display will ash for four seconds and reset
to the actual room temperature.
• Once the stove reaches within 3°F of the desired
temperature set point, it returns to the heat range
that the stove was set on before it was switched
to T-Stat mode (if the stove was running on heat
range “5” when switched to T-stat mode when
it gets within 3°F of the set point it will return to
heat range “5”).
• Once the stove reaches the desired set-point, the
stove will drop to heat range “1”.
• When room temperature drops below desired
set-point the stove will ramp back up until it
reaches the desired temperature.

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.
Burning these materials may result in release of
toxic fumes or render the heater ineffective and
cause smoke.
PROPER FUEL
ATTENTION:
THIS APPLIANCE IS DESIGNED FOR THE USE
OF PELLETIZED FUEL THAT MEET OR EXCEED
THE STANDARD SET BY THE PELLET FUEL
INSTITUTE (PFI).
Your pellet stove is designed to burn premium
hardwood pellets that comply with the Pellet Fuels
Institute (PFI) standard (minimum of 40 lbs density
per cubic ft, 1/4” to 5/16” diameter, length no greater
than 1.5”, not less than 8,200 BTU/lb, moisture under
8% by weight, ash under 1% by weight, and salt
under 300 parts per million). Pellets that are soft,
contain excessive amounts of loose sawdust, have
been, or are wet, will result in reduced performance.
Store your pellets in a dry place. DO NOT store the
fuel within the installation clearances of the unit
or within the space required for refuelling and ash
removal. Doing so could result in a house re. Do not
over re or use volatile fuels or combustibles, doing
so may cause a personal and property damage
hazards. 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:
• 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.
• Binders – Some pellets are produced with
materials to hold the together, or “bind” them.
• 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.
CAUTION:
THE MOVING PARTS OF THIS STOVE ARE
PROPELLED BY HIGH TORQUE ELECTRIC
MOTORS. KEEP ALL BODY PARTS AWAY FROM
THE AUGER WHILE THE STOVE IS PLUGGED
INTO AN ELECTRICAL OUTLET. THESE MOVING
PARTS MAY BEGIN TO MOVE AT ANY TIME
WHILE THE STOVE IS PLUGGED IN.
OPERATION INSTRUCTIONS

11
CAUTION:
KEEP FOREIGN OBJECTS OUT OF THE HOPPER.
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 sufcient).
Never use abrasive cleaners on the glass or door.
Check fuel in the hopper, and rell 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 the 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 the stovetop during this period because the paint
could be affected. Attempts to achieve heat output
rates that exceed heater design specications can
result in permanent damage to the heater.
AUTOMATIC IGNITOR
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 1/4 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.
5. 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. 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 efciency 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 closing
the damper a bit. On higher feed rates, the damper
should be open more. 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 1/4 of the way. If damper is open to far, it can cause
the re to go out.

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”
REFUELLING
Never place your hand near the auger while the
stove is in operation. We recommend that you not
let the hopper drop below 1/4 full.
CAUTION:
• THE HOPPER AND STOVE TOP WILL BE
HOT DURING OPERATION; THEREFORE,
YOU SHOULD ALWAYS USE SOME TYPE
OF HAND PROTECTION WHEN REFUELING
YOUR STOVE.
• DO NOT TOUCH THE HOT SURFACES OF
THE STOVE. EDUCATE ALL CHILDREN ON
THE DANGERS OF A HIGH-TEMPERATURE
STOVE. YOUNG CHILDREN SHOULD BE
SUPERVISED WHEN THEY ARE IN THE SAME
ROOM AS THE STOVE.
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.
WARNING:
• KEEP HOPPER LID CLOSED AT ALL TIMES
EXCEPT WHEN REFILLING.
• DO NOT OVERFILL HOPPER.
SHUTDOWN PROCEDURE
WARNING:
NEVERSHUTDOWNTHIS UNITBYUNPLUGGING
IT FROM THE POWER SOURCE.
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.
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.
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 cleanouts are located inside the cabinet doors,

on the lower front corners of the heat exchanger.
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 the AV15E AshVac vacuum. The AV15E AshVac
is designed for ash removal. Some regular vacuum
cleaner (i.e. shop vacs) may leak ash into the room.
DO NOT VACUUM HOT ASH.

CREOSOTE FORMATION, INSPECTION,
& REMOVAL
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
efciency, pellet stoves can accumulate creosote
under certain conditions. The chimney connector
and chimney should be inspected by a qualied
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
CAUTION:
THE EXHAUST SYSTEM SHOULD BE CHECKED
MONTHLY DURING THE BURNING SEASON FOR
ANY BUILD-UP OF SOOT OR CREOSOTE.
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.

ASH REMOVAL & DISPOSAL
CAUTION:
ALLOW THE STOVE TO COOL BEFORE
PERFORMING ANY MAINTENANCE OR
CLEANING. ASHES MUST BE DISPOSED IN A
METAL CONTAINER WITH A TIGHT FITTING
LID. THE CLOSED CONTAINER OF ASHES
SHOULD BE PLACED ON A NON-COMBUSTIBLE
SURFACE OR ON THE GROUND, WELL AWAY
FROM ALL COMBUSTIBLE MATERIALS,
PENDING FINAL DISPOSAL.
Remove the ashes periodically to avoid unnecessary
ash build up. Remove ashes when unit has cooled.
Ashes should be placed in a metal container with a
tight tting lid. The closed container of ashes should
be placed on a noncombustible 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
embers have been thoroughly cooled. The container
shall not be used for other trash or waste disposal. If
combined with combustible substances, ashes and
embers may ignite. Ash removal is as follows:
1. Let the re burn out and allow the unit to cool
to room temperature.
2. Make sure the pellet stove is at room
temperature before touching. Open the door,
remove the burn pot and empty it into a metal
container.
3. Vacuum ashes from the rebox. 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.
4. Reinstall the burn pot.
SMOKE & 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 conned areas
can be dangerous. Make sure you 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.
CHECK & 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 & 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. If you have indoor pets your power motors
should be inspected monthly to make sure they
are free of animal hair build up. Animal hair build
up in blowers can result in poor performance or
unforeseen safety hazards.
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
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.
Do not attempt to operate the unit with broken
glass. Replacement glass may be purchased from
your U.S. Stove dealer. If glass is broken, follow these
removal procedures:
1. Once the heater has cooled, remove the door
from the heater.
2. Remove the rope gasket from the door along
with the screws holding the glass retainer in
place and the glass retainer.

3. While wearing leather gloves (or any other
gloves suitable for handling broken glass),
carefully remove any loose pieces of glass from
the door frame. Dispose of all broken glass
properly.
4. Replace the glass and gasket, making sure the
gasket runs the full perimeter of the glass edge.
5. Re-install the new glass by re-attaching the
retainers and screws, be careful not to over
tighten the screws for this could damage 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.

TROUBLE SHOOTING GUIDE
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. Refer to diagrams on page 25 to help locate indicated parts.
For the sake of troubleshooting and using this guide to assist you, 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)
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.
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.
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.
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.
High Limit Switch is malfunctioning. If the other items check out OK, replace the high limit switch.

Airow 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.
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.
The rebox is not properly sealed. Make sure the door is closed and that the gasket is in good
shape.
Vent pipe is incorrectly installed. Check to make sure vent pipe installation meets criteria in
owner’s manual.
The airow switch wire connections are
bad.
Check the connectors that attach the gray wires to the air
switch.
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.
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.
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.
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.

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.
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.
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.
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

STOVE FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes Possible Remedies: (Unplug stove rst when possible)
Air damper open too far for ignition.
Push the air damper in closer to the side of the stove for
startup. In some situations it may be necessary to have the
damper completely closed for ignition to take place. After
there is a ame, the damper can then be adjusted for the
desired feed setting.
Blockage in igniter tube or inlet for igniter
tube.
Find the igniter housing on the backside of the rewall. The
air intake hole is a small hole located on bottom side of the
housing. Make sure it is clear. Also, look from the front of the
stove to make sure there is not any debris around the igniter
element inside of the igniter housing.
The burnpot is not pushed completely to
the rear of the rebox.
Make sure that the air intake collar on the burnpot is touching
the rear wall of the rebox.
Bad igniter element.
Put power directly to the igniter element. Watch the tip of the
igniter from the front of the stove. After about 2 minutes the
tip should glow. If it does not, the element is bad.
The control board is not sending power
to the igniter.
Check the voltage going to the igniter during startup. It should
be a full current. If the voltage is lower than full current, check
the wiring. If the wiring checks out good, the board is bad.
SMOKE SMELL COMING BACK INTO THE HOME
Possible Causes Possible Remedies: (Unplug stove rst when possible)
There is a leak in the vent pipe system.
Inspect all vent pipe connections. Make sure they are sealed
with RTV silicone that has a temperature rating on 500 degree
F or higher. Also, seal joints with UL-181-AP foil tape. Also, make
sure the square to round adapter piece on the combustion
blower has been properly sealed with the same RTV.
The gasket on the combustion blower
has gone bad.
Inspect both gaskets on the combustion blower to make sure
they are in good shape.
Because it is a wood-burning device, your pellet heater may emit a faint wood-burning odor. If this
increases beyond normal, or if you notice an unusual soot build-up on walls or furniture, check your
exhaust system carefully for leaks. All joints should be properly sealed. Also clean your stove, following
instructions in “MAINTENANCE”. If problem persists, contact your dealer.

Clean any dust off of the windings and fan blades. If cleaning
the blower does not help, the blower may be bad.
Circuit board malfunction.
Test the current going to the convection blower. If there is
power being sent to the blower when it is shut off, then the
control board is ne. If there is NOT power being sent to the
blower when it shuts off during operation, then you have a
bad control board.
