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 fl ue system other than the way ex-
plained 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 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 backpuffi 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 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.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable collection of fl y ash and to permit periodic cleaning of the exhaust
system. 90-degree elbows accumulate fl y ash and soot thereby reducing exhaust fl 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 sundeck 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.
INSTALLATION
VENTING REQUIREMENTS
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.

FIGURE 7
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 (see FIGURE 7).
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 in.(76mm) adapter is added before the clean-out tee.
You must use the proper ceiling support fl anges and roof fl 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 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.

depending on your installation.
FIGURE 9
TYPICAL FRESH AIR TERMINATION
FIGURE 10
FIGURE 8
EXHAUST/INLET LOCATIONS
OUTSIDE AIR SUPPLY (optional, unless installing in a mobile home)
Adequate ventilation air is required to operate this heater. During operation, the heater draws air for combustion which
can be assisted by the installation of outside combustion air inlets. However, certain weather conditions such as icing
or use of kitchen exhaust fans may impact and reduce the effectiveness of vents. It is important to note that room air
starvation will negatively impact the operation of the heater.
Depending on your location and home construction, outside air may be necessary for optimal performance.
Metal pipe (solid or fl 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 fi t over, not inside, the outside air connection to the heater.
SPECIAL MOBILE HOME REQUIREMENTS
WARNING! - DO NOT INSTALL IN A SLEEPING ROOM
CAUTION! - THE STRUCTURAL INTEGRITY OF THE
MOBILE HOME FLOOR, WALL, AND CEILING/ROOF
MUST BE MAINTAINED.
NOTE: Installation should be in accordance with the Manu-
factured Home and Safety Standard (HUD), CFR 3280, Part
24.
In addition to the previously detailed installation requirements,

COMBUSTION AIR SUPPLY
If outdoor combustion air is supplied the heater must be attached to the structure.
For a mobile home installation the stove must be connected to an outside source of combustion air. A 2” inside diameter
metallic pipe, either fl exible or rigid, may be attached to the inlet at the stove’s rear.
A rodent guard (minimum ¼” wire
mesh)/wind hood must be used at the terminus.
All connections must be secured and airtight by either using the appro-
priately sized hose clamp and/or UL-181-AP foil tape.
For mobile home installations only: 2” inside diameter pipe may be used for the fi rst 5 feet of combustion air supply
run. From 5 to 10 feet use 2 ¾” inside diameter pipe. No combustion air supply may exceed 10 feet.
SOURCES OF OUTSIDE COMBUSTION AIR
In fi replaces
• Chimney top.
• Ash clean out door.
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air is easily available to the air inlet. A closeable outs
ide air reg-
ister can be used in tightly insulated homes.
In insert installations, fl ashing vents should not be restricted. The fl ashing
should not necessarily seal the fi replace face.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
INSERT INSTALLATIONS
Insert installations must be vented with 3” or 4” pipe. Pipe may be single wall stainless steel fl exible pipe. Vent may termi-
nate within chimney beyond a blanking plate or extend to the chimney top. See “COMBUSTION AIR SUPPLY” for outside
air access information.
The fi replace and chimney should be cleaned thoroughly before starting the installation. We suggest painting the

INSTALLATION IN TO A FACTORY BUILT (METAL) FIREPLACE
When installing into a factory built fi replace, the fi rebox must accept the insert without modifi cation other than re-
moving bolted or screwed together pieces such as smoke shelf/defl ectors, ash lips, screen or door tracks and damper
assemblies. These items must be reinstalled to restore the fi replace to its original operating condition if the insert is
removed and not replaced. The removal of any part must not alter the integrity of the listed fi replace in any way.
The factory built fi replace must be listed per UL 127. Installation must include a full height listed chimney liner meet-
ing type HT requirements (2100
o
F) per 1777 (U.S.). The liner must be securely attached to the insert fl ue col
lar and
the chimney top. The damper area must be sealed to prevent room air passage to chimney cavity.
Alteration of the fi replace in any manner is not permitted except with the following exceptions:
• External trim pieces, which do not affect the operation of the fi replace, may be removed proving they can be stored
on or within, the fi replace for re-assembly if the insert is removed.
• The fi replace damper may be removed to install the chimney liner.
Circulating air chambers, louvers or cooling air inlet or outlet ports (i.e. in a steel fi replace liner or metal heat circulator)
shall not be blocked.
Means must be provided for removal of the insert to clean the chimney fl ue.
A permanent metal warning label must be attached to the back wall of the fi replace opening stating the following:
• “This fi replace has been altered to accommodate a fi replace insert and should be inspected by a qualifi ed person
prior to re-use as a conventional fi replace.”
• This label is available upon request.

PANEL CONTROLS
The blowers and automatic fuel supply are controlled from a panel on the top of the VG5770. The control panel func-
tions are a follows.
A. ON/OFF SWITCH (“POWER” BUTTON)
• When pushed, the stove will automatically ignite. No other fi 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 fi re should start in approxi-
mately 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 accord-
ingly, 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.
CONTROL PANEL
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 fl 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.

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 fl 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 fi 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. Pel-
lets can be screened before being placed in hopper to remove most fi 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 fi rebox, and then reinstall
burn pot. Clean door glass if necessary (a dry cloth or paper towel is usually suffi cient). Never use abrasive cleaners
on the glass or door. Check fuel in the hopper, and refi ll if necessary.
NOTE: The VG5770 Hopper can hold up to 60 lbs. of pellets.
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 fi rst few fi res, your stove will emit an odor as the high temperature paint cures or becomes sea-
soned to the metal. Maintaining smaller fi res will minimize this. Avoid placing items on stove top during this period
because paint could be affected.
Attempts to achieve heat output rates that exceed heater design specifi cations can result in permanent damage to the
heater.

OPERATION
AUTOMATIC IGNITOR
Fill hopper and clean burn pot.
1. Press “On/Off” button. Make sure green light comes on.
2. The damper should be completely closed or open no more than ¼ of the way during start-up. This will vary de-
pending on your installation and elevation. Once fi re is established adjust for desired fl ame increasing the amount
the damper is open as the heat setting is increased. (See “DAMPER CONTROL”)
3. Adjust feed rate to desired setting by pressing “Heat Level Advance” button.
If fi 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 com-
bustion 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 effi 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 fi re’s appearance. A low, reddish, dirty fi re can be improved by turning the
dampener slightly to the right. A “blow torch” fi 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 fi 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 fi 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 fi 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 fl ashing “E3”
REFUELING
• The hopper and stove top will be hot during operation; therefore, you should always use some type of hand pro-
tection 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.
TAMPER WARNING
This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is against federal regula-
tions to alter this setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in
this manual.
21
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 fi 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 ser-
vice 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.
WARNING: Never shut down this unit by unplugging it from the power source.
OPERATION
22
Failure to clean and maintain this unit as indicated can result in poor performance, safety hazards,
fire, and even death.
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 flue gas may result.
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 fl ue or a newly
started fi re or from a slow-burning fi re. As a result, creosote residue accumulates on the fl ue lining. When ignited, this
creosote makes an extremely hot fi re, which may damage the chimney or even destroy the house. Despite their high
effi ciency, 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 fl ow. It should therefore be periodically removed.
Inspection and Removal – The chimney connector and chimney should be inspected by a qualifi ed person annually
or per ton of pellets to determine if a creosote or fl y ash build-up has occurred. If creosote has accumulated, it should
be removed to reduce the risk of a chimney fi 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 specifi cally designed for the type of chimney in use. A
qualifi ed 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.
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
fl y ash out of the heat exchanger. The cleanouts are located inside the cabinet doors, on the lower front corners of
the heat exchanger.
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
ASH DISPOSAL
Remove ashes when unit has cooled. Ashes should be placed in a metal container with a tight fi tting lid. The closed
container of ashes should be placed on a noncombustible fl oor or on the ground, well away from all combustible ma-
terials, pending fi 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.
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 confi ned areas can be dan-
gerous. 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 AND CLEAN THE HOPPER
Check the hopper periodically to determine if there is any sawdust (fi nes) that is building up in the feed system or
pellets that are sticking to the hopper surface. Clean as needed.
MAINTENANCE
23
MAINTENANCE
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 5/8” 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 autho-
rized 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, remove the four (4) screws and glass retainers. 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. ONLY high temperature ceramic glass of the correct size and thickness may be used. DO NOT substitute
alternative materials for the glass. Contact your authorized dealer to obtain this glass. 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 fi rst fi re of the heating season, check the outside area around the exhaust and air intake systems for obstruc-
tions. Clean and remove any fl 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 fl 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 fi 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.

When your stove acts out of the ordinary, the fi 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 fi 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 fl 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.
TROUBLE SHOOTING GUIDE
Display is Flashing “E1”
Possible Causes Possible Remedies: (Unplug stove fi 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 ex-
tended 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 oper-
ating 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.
ATTENTION: This wood heater needs periodic inspection and repair for proper operation. It is against federal regula-
tions to operate this wood heater in a manner inconsistent with operating instructions in this manual.

TROUBLE SHOOTING GUIDE
Display is Flashing “E2”
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. Airfl ow switch hose or stove attachment pipes for hose
are blocked.
Unhook air hose from the air switch and blow through it.
If air fl ows freely, the hose and tube are fi ne. If air will not
fl ow throw the hose, use a wire coat hanger to clear the
blockage.
2. The air inlet, burnpot, interior combustion air cham-
bers, combustion blower, or exhaust pipe are blocked
with ash or foreign material.
Follow all cleaning procedures in the maintenance sec-
tion of the owner’s manual.
3. The fi 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 airfl ow 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 cur-
rent. 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 con-
nected, you have a bad control board.
8. Control board not sending power to air switch.
There should be a 5-volt current (approximately) go-
ing 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 en-
tirely off the stove and the air switch fi 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.

Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. The hopper is out of pellets Refi ll 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 damp-
ener 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 sec-
tion 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 connec-
tions. 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 discon-
necting 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 fi 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.

auger shaft. Gently lift the auger shaft straight up so that
the end of the auger shaft comes up out of the bottom
auger bushing. Next, remove the two nuts that hold the
top auger biscuit in. Then rotate the bottom end of the
auger shaft up towards you until you can lift the shaft out
of the stove. After you have removed the shaft, inspect
it for bent fl ights, burrs, or broken welds. Remove any
foreign material that might have caused the jam. Also,
check the auger tube for signs of damage such as burrs,
rough spots, or grooves cut into the metal that could have
caused a 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.
Display is Flashing “E5”
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. The stove automaticaly fl ashes "E5" when turned on
The T-stat sensor has come unpluged form the control
board. Check to see if the sensor is unpluged. If the
sensor is not unpluged then the sensor is damaged or
has a short. If the sensor is damaged or has a short it
will need to be replaced.

TROUBLE SHOOTING GUIDE
STOVE FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. 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 fl ame, the damper can then be adjusted for the
desired feed setting.
2. Blockage in igniter tube or inlet for igniter tube. Find the igniter housing on the backside of the fi 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.
3. The burnpot is not pushed completely to the rear of
the fi rebox.
Make sure that the air intake collar on the burnpot is touching
the rear wall of the fi rebox.
4. 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.
5. 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 fi rst when possible)
1. 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.
2. 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.
CONVECTION BLOWER SHUTS OFF AND COMES BACK ON
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. The convection blower is overheating and tripping
the internal temperature shutoff.
Clean any dust off of the windings and fan blades. If cleaning
the blower does not help, the blower may be bad.
2. 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 fi ne. If there is NOT power being sent to the
blower when it shuts off during operation, then you have a
bad control board.

TROUBLE SHOOTING GUIDE
STOVE WILL NOT FEED PELLETS, BUT FUEL FEED LIGHT COMES ON AS DESIGNED
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. High limit switch has tripped or is defective. Wait for the stove to cool for about 30 - 45 minutes. Locate
the High Limit thermodisc and press the reset button on the
back of it. If the heater will not restart, check the thermodisc
to see if it’s bad. To test if the thermodisc is bad, you can
bypass it as described previously for the POF thermodisc.
2. Bad Auger Motor. 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.
3. Auger Jam. Start by emptying the hopper. Then remove the auger
motor by removing the auger pin. Remove the auger shaft
inspection plate in the hopper so that you can see the auger
shaft. Gently lift the auger shaft straight up so that the
end of the auger shaft comes up out of the bottom auger
bushing. Next, remove the two nuts that hold the top auger
biscuit in. Then rotate the bottom end of the auger shaft
up towards you until you can lift the shaft out of the stove.
After you have removed the shaft, inspect it for bent fl ights,
burrs, or broken welds. Remove any foreign material that
might have caused the jam. Also, check the auger tube for
signs of damage such as burrs, rough spots, or grooves
cut into the metal that could have caused a jam.
4. Loose wire or connector. Check all wires and connectors that connector to the auger
motor, high limit switch, and the Molex connector.
5. Bad control board. If the fuse is good, the wires and connectors check out
good, and the high limit switch did not trip, test for power
going to the auger motor. If there is not a full current going
to the auger motor when the fuel feed light is on, you have
a bad control board.
HIGH LIMIT SWITCH KEEPS TRIPPING
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. The convection blower is overheating and tripping the
internal temperature shutoff.
Clean any dust off of the windings and fan blades. 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 consumer.
5. High limit switch is malfunctioning. If the other items check out OK, replace the high limit switch.

TROUBLE SHOOTING GUIDE
• GLASS “SOOT’S” UP AT A VERY FAST RATE
• FLAME IS LAZY, DARK, AND HAS BLACK TIPS
• AFTER STOVE HAS BEEN ON FOR A WHILE, THE BURNPOT OVERFILLS
Possible Causes Possible Remedies: (Unplug stove fi rst when possible)
1. Stove or vent pipe is dirty, which restricts airfl ow through
the burnpot.
Follow all cleaning procedure in the maintenance section
of the owner’s manual.
2. Vent pipe installed improperly. Check to make sure the vent pipe has been installed
according to the criteria in the owner’s manual.
3. Air damper is set too far in (closed) for a higher setting. Pull the damper knob farther out away from the side of the
stove and try to burn the unit again.
4. Burnpot holes are blocked. Remove the burnpot and thoroughly clean it.
5. Air damper is broken. Visually inspect the damper assembly. Make sure the
damper plate is attached to the damper rod. When the
damper rod is moved the plate should move with it.
6. Blockage in air intake pipe. Visually inspect the air intake pipe that leads into the
burnpot for foreign material.
7. Combustion blower is not spinning fast enough. Test the RPM on the blower after the blades have been
cleaned. The RPM should be approximately 3000 RPM.
8. Bad Pellets.
(Applies to GLASS “SOOT’S” UP AT A VERY FAST
RATE Only)
The brand of pellets or the batch of pellets that are being
used may be of poor quality. If possible, try a different brand
of pellets. You might also want to try a brand that is made
from a different type of wood (softwood vs. hardwood).
Different woods have different characteristics when being
burned.
