INSTALLATION

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.
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 floor of the mobile home using two 1/4” lag bolts that are long enough to go through both a hearth pad, if used, and the floor 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 certified ceiling fire 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 officials as other codes may apply.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
· A UL listed 3″ or 4″ type “PL” pellet vent exhaust system must be used for installation and attached to the pipe connector provided on the back of the heater.

Use a 3″ to 4″ adapter for 4″ pipe. A 4″ PL is required for elevations above 2,500 feet above sea level.
· Do not terminate vent in any enclosed or semi-enclosed area, such as; carports, garage, attic, crawl space, under a sundeck or porch, narrow walkway or close area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc.
· Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be required.
· Do not install a flue damper in the exhaust vent of this unit.
· Termination must exhaust above air inlet elevation. Installation MUST include three (3) vertical feet of pellet vent pipe. This will create some natural draft to prevent the possibility of smoke or odor during appliance shutdown and to keep exhaust from causing a nuisance or hazard from exposing people or shrubs to high temperatures. Do not connect this unit to a chimney flue serving another appliance. Do not connect directly to a masonry chimney.
· The installation must include a cleanout tee to enable collection of fly ash and to permit periodic cleaning of the exhaust system. 90° elbows accumulate fly ash and soot thereby reducing exhaust flow and performance of the heater. Each elbow or tee reduces draft potential by 30% to 50%. Use no more than 180 degrees of elbows (two 90° elbows, or two 45° and one 90° elbow, etc.) and one cleanout tee to maintain adequate draft. Cleanout tees and elbows should not be connected to the rear of the unit unless a 3-inch adapter is used.
· Total length of horizontal vent must not exceed 48″ (4ft.)/1,200mm. The maximum recommended vertical venting height is 12-feet for 3-inch type “PL” vent. For venting higher than 12-feet, 4-inch “PL” vent must be used. All joints in the vent system must be fastened by at least 3 screws, and all joints must be sealed with RTV silicone sealer 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.
NOTE: These are guidelines only. Proper venting is accomplished by design and necessary requirements. In most installations 3 inch diameter venting is adequate. If it does not vent properly you will have to change it to 4 inches. You should not exceed 4 inch diameter venting.
DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM

INSTALLATION

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 backpuffing 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. It is recommended that only an authorized installer install your heater, preferably an NFI certified specialist. The following installation guidelines must be followed to ensure conformity with both the safety listing of this heater and to local building codes.

I. Min. 3-ft clearance from a forced air intake of any appliance.
J. Min. 2-ft clearance below eaves or overhang.
K. Min. 1-ft clearance horizontally from combustible wall.
L. Must be a minimum of 36-inches above the roof and 24-inches above the highest point or the roof within 10-feet.
INSTALLATION AS A BUILT-IN FIREPLACE
A continuous sheet of non-combustible floor protection must be installed underneath the unit to prevent the possibility of embers falling through to the combustible floor. If the floor beneath the unit is of non-combustible material, the protector is not required. See the “Clearance to Combustibles” section of this manual for installation clearances.

VENT TERMINATION CLEARANCES

A MINIMUM OF 3 VERTICAL FEET OF PIPE OUTSIDE THE
HOME IS REQUIRED!

D. Min. 4-ft clearance below or beside any door or window that opens.
E. Min. 1-ft clearance above any door or window that opens.
F. Min. 3-ft clearance from any adjacent building.
G. Min. 7-ft clearance from any grade when adjacent to public walkways.
H. Min. 2-ft clearance above any grass, plants, or other combustible materials.

ALTERNATIVE EXHAUST VENTING
Depending on your installation, you might consider routing your cleanout tee as illustrated below for ease of cleaning. The access panel in the right side facade allows you to reach the tee from the front side of the unit if venting is assembled as shown. The cleanout tee is attached to a 90° elbow mounted to the unit then rotated at approx. 15-20 degrees. A 12 inch section of “PL” vent is connected to reach the top of the unit to which a flexible

Manual

Turning the heater OFF/ON, as well as adjustments for the fuel feed rate and room fan speed are performed by pressing the appropriate button(s) on the control panel.
This unit has two fuel operation modes. It may also be changed between an automatic operation or a manual operation in either of the fuel modes.
· Pressing the “ON” button on the control panel will begin the start-up sequence for the heater. The startup sequence differs depending on which fuel operation mode you select (see Lighting Instructions for details). Pressing and holding the “ON” button will rotate the auger continuously until the button is released, which feeds additional fuel.
· Pressing the “OFF” button on the control panel will cause the heater to enter its shut-down sequence. The fuel feed system will stop pulling fuel from the hopper and, once the fire goes out and the heater cools down, the fans will stop running.
· Pressing the “Heat Range” arrows, up or down, will adjust the amount of fuel being delivered to the burnpot.
· The draft fan (exhaust) will come on as soon as the “ON” button is pressed. The fan will automatically adjust its speed in accordance to the heat range setting. However, this speed can be manually operated by

pressing the “Draft Fan” arrows up or down. “Draft Fan” when pressed, the display will show “DF-A”, which is automatic. Press the arrows again to adjust fan speed. When adjusting the draft fan setting, try only
· One setting above or below the heat setting. It is better to leave the heater in the automatic mode and adjust the manual draft slide to control the combustion air.
· The room fan will come on once the unit has reached operating temperature (approx. 110°F). By pressing the “Room Fan” buttons, the display will show “RFA” which is automatic or “RF-1” through “RF-9” for manual settings. In auto mode, the room fan’s speed will automatically be adjusted in accordance with the heat range setting. By pressing the “Room Fan” up arrow, you can adjust the fan speed setting up to “RF-9”. The fan speed can be adjusted to a higher setting than the heat setting but not lower than the corresponding heat range.
· The “Aux” button is for Agitator operation. When the unit is “OFF” and the heater is cool, pressing the “Aux” arrows will rotate the agitator for easy removal for cleaning. The agitator, when in Automatic mode, will operate at set intervals. However, these can be changed by pressing the arrows on the “Aux” button. The agitator can be adjusted from 0 to 9, setting “0” is off and setting “9” is high.
· The “Auger Delay” button can be used to pause rotation of the Auger and Agitator for approx. 1 minute. This can be cancelled by pressing the “ON” button. The “Auger Delay” is normally used only during the start up cycle to slow the fuel delivery down during the initial ignition.
· The “Mode” button is used to switch between manual and automatic mode. When in auto mode, the fan, auger, and agitator will operate at preset intervals unless changed manually using the buttons mentioned above. When in manual mode, the draft fan (exhaust) will operate at full speed (100%), so the air must be controlled with the manual slide damper just below the viewing door. When the heater is in the manual mode, the optional thermostat will not properly control the unit.
· During normal operation, the unit is constantly monitored for problems. In the event of an error condition, the unit will stop and an error will be displayed. See the list of error codes found at the end of this manual.

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). IN ADDITION TO PELLET FUEL, THIS STOVE IS APPROVED BY THE EPA TO BURN DRIED CORN.
Your multi-fuel 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 fire. Do not over fire or use volatile fuels or combustibles, doing so may cause a personal and property damage hazards. 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 flights, 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 fire 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 fines.
· 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.
· Your corn needs to be clean and dry, and you should never burn any seed corn or other chemically treated corn, old corn, corn with mildew or mold, etc.
· Corn should be dried to 11-12%. If you are buying corn from a retail supplier, make sure it is intended to be sold (and burned) as fuel. If you are buying direct from a farmer in bulk, make sure you communicate what you are doing with the corn and that you need it dried sufficiently so you don’t have problems.
· If your corn has too much moisture, it will cause a variety of problems including lighting, consistent flame and heat, smoke, and more.

OPERATION INSTRUCTIONS

· Corn burns hotter than wood pellets. Be prepared for more heat output. Sometimes a corn burning appliance can heat your home to your desired temp on its lowest level. When you first start burning corn, especially if you’re used to wood pellets, you’ll want to start out on a lower setting and slowly turn it up as needed.
· When you burn corn, you’ll occasionally get “Klinkers” which is a build up. You can eliminate or greatly reduce any buildup of the Klinker by making sure that your corn is free from dust, dirt, corn fines, pieces of stalk and other debris. Having your fuel at 11-12 percent moisture will also help out in reducing the Klinker buildup. Remember that you can mix corn with wood pellets. Doing so will extend one fuel, as well as help avoid klinkers.
CAUTION:
· KEEP FOREIGN OBJECTS OUT OF THE HOPPER.
· 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.
PRE-START-UP CHECK
Remove burn pot, making sure it is clean and none of the air holes are plugged. Clean the firebox, and then reinstall burn pot. Clean door glass if necessary (a dry cloth or paper towel is usually sufficient). Never use abrasive cleaners on the glass or door. Choose which fuel setting that you wish to operate in. Do this by first pressing the “ON” button, then press the “Heat Range” Up and Down arrows together for approximately 3-4 seconds and release. A “C” or “P” in the first digit of the display will indicate the mode. The “ON” led will be blinking and the display will show “CR-1” or “PR-1”, depending on the mode. The “Heat Range” indicator LED and the “Auto” LED should be lit and the dash in the Heat Range display should be flashing. You will notice the draft fan starts immediately. If you press the “Heat Setting” button up, the draft fan changes speed, increasing speed the higher the heat setting. You should begin to see the igniter, located in the center and behind the burnpot, begin to glow after a short period of time. In CR-1, the auger and agitator will start rotating after a few minutes, allowing for proper fuel ignition. In PR-1, the auger will turn immediately, then the agitator will begin to rotate once the heater reaches operating temperature. Note: The room fan will not operate at this time, as a temperature of at least 110°F

must be reached before operating. If proper operation of your heater is confirmed, press the “OFF” button, then fill your hopper with fuel. Ensure there is no foreign matter in your fuel, hopper or burnpot.
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:
· Make sure the burn pot is free of pellets.
· DO NOT open the viewing door.
· DO NOT add pellets to the burn pot by hand.
NOTE: During the first few fires, your stove will emit an odor as the high- temperature paint cures or becomes seasoned to the metal. Maintaining smaller fires 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 specifications can result in permanent damage to the heater.
OPTIMAL OPERATION
This multi-fuel stove has been certified by the US EPA to meet strict 2020 guidelines. To Insure this unit produces the optimal minimal emissions, it is critical to follow the following guidelines. To achieve a “high burn” your stove should be set on setting 5 with the damper fully open. To achieve a “medium burn” your stove should be set on setting 1 with the damper fully closed. To achieve a “low burn” your stove should be set on setting 1 with the damper closed. Settings 2, 3 & 4 will give you a higher heat output above medium and the damper should be open for these settings. 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.
IGNITOR
· Close all doors, lids, and cleanouts.
· Press the “ON” button and select desired heat range. This will start the ignition sequence.
· At this point, the igniter will come on and run for preset time limit (approximately 9 minutes). The auger will begin to turn and feed fuel into the burnpot. After the 9 minutes or if the heater reaches operating temperature, the igniter will shut off and normal operation will begin.

OPERATION INSTRUCTIONS

· Make fine adjustments to the air/fuel with the damper located centered, under the hearth.
· Once the heater reaches warm temperature, the room fan will start to circulate air into the room.
· If you would like to increase the life of your ignitor, you can run your heater in the “CR” mode. However, you must place pellets in the burnpot, up to the igniter level as shown in the illustration below for auto ignition. Close the door and press the “ON” button. The igniter only runs approximately half the time in “CR” as oppose to the “PR” mode.

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.

OPENING DOOR
CAUTION: · DO NOT OPERATE YOUR STOVE WITH THE
VIEWING DOOR OPEN. THE AUGER WILL NOT FEED PELLETS UNDER THESE CIRCUMSTANCES AND A SAFETY CONCERN MAY ARISE FROM SPARKS OR FUMES ENTERING THE ROOM. · THE DOOR MUST BE CLOSED AND SEALED DURING OPERATION.
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.
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.
REFUELLING
WARNING: · KEEP HOPPER LID CLOSED AT ALL TIMES
EXCEPT WHEN REFILLING. · DO NOT OVERFILL HOPPER.
CAUTION: · 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.

SHUTDOWN PROCEDURE
WARNING:
NEVER SHUT DOWN THIS UNIT BY UNPLUGGING IT FROM THE POWER SOURCE.
Pressing the OFF button will cause the heater to enter a shutdown mode. If the heater has reached operating temperature, the “OFF” Indicator will blink until the shutdown procedure succeeds in lowering the heater temperature. The Room Fan will stay on to cool the heater, and the Exhaust Fan will stay on to remove smoke and heat from the combustion chamber. The Agitator will rotate continuously until shutdown is complete. The Auger will bump the fuel out every few seconds to prevent the fuel in the auger from burning. Once the temperature of the burn chamber falls below approximately 90°F and the pressure switch detects that the door is closed, the fans will stop and the Auger will run for a few seconds to purge the auger system of any burned fuel. At this point, the “OFF” Indicator will go out and the heater will turn completely off. If during burning, the heater reached at least 120°F, the shutdown procedure will include a 15 minute shutdown cycle that will keep the heater in the shutdown state for at least 15 minutes regardless of whether it is cool or pressure is detected. The 15 minute cycle can be turned off by pressing the off button during shutdown. This will cause the system to exit shutdown and return to the “OFF” mode as soon as the door is closed and the heater is cool. Continue to monitor the heater / insert after the shutdown procedure has begun. And remember, varying ambient conditions may result in a lengthy period of time for adequate cool down and the resultant shut down. Be patient, this is normal. The control board is telling the heater / insert to gradually “shut down,” rather than initiate a sudden halt of fuel to the fire pot. In this way, the possibility of smoke entering the home is avoided.

INTERIOR CHAMBERS
· 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.
· Remove the small clean-out slides in the lower corners of the firebox. Tap the sides of the burn chamber with a wooden stick. Do not tap the firewall behind the burn box as it may damage the ceramic firebrick. Scrape the fly ash from the clean-out chambers toward the front of the burn chamber. Remove the fly ash from the burn chamber and replace the clean-outs.

· Remove the ash pan and dump the ash into a metal container.
· Cleaning of the exhaust system will depend upon the ash and debris content of your fuel. If your fuel has a high ash content and/or significant debris in it, your exhaust system will require weekly cleaning. Cleaner fuels will allow for monthly cleaning of the exhaust system. Remove the exhaust pipe from the back of your heater and remove any ash that may have collected in the pipes. Replace the pipes to the heater and seal with high temperature seal tape. If you have installed proper clean out tees you will not have to take the chimney sections apart.

MAINTENANCE

NEVER OPERATE THIS PRODUCT WHILE UNATTENDED

CAUTION:
· FAILURE TO CLEAN AND MAINTAIN THIS UNIT AS INDICATED CAN RESULT IN POOR PERFORMANCE, SAFETY HAZARDS, FIRE, AND EVEN DEATH.
· NEVER PERFORM ANY INSPECTIONS, CLEANING, OR MAINTENANCE ON A HOT STOVE.
· 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.
· DO NOT OPERATE STOVE WITH BROKEN GLASS, LEAKAGE OF FLUE GAS MAY RESULT.
· ATTEMPTS TO ACHIEVE HEAT OUTPUT RATES THAT EXCEED HEATER DESIGN SPECIFICATIONS CAN RESULT IN PERMANENT DAMAGE TO THE HEATER.
CREOSOTE FORMATION, INSPECTION, & REMOVAL
CAUTION:
THE EXHAUST SYSTEM SHOULD BE CHECKED MONTHLY DURING THE BURNING SEASON FOR
ANY BUILD-UP OF SOOT OR CREOSOTE.
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 flue or a newly started fire or from a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire, which may damage the chimney or even destroy the house. Despite their high efficiency, pellet stoves can accumulate creosote under certain conditions. The chimney connector and chimney should be inspected by a qualified person annually or per ton of pellets to determine if a creosote or fly ash buildup has occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney fire. 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 specifically designed for the

type of chimney in use. A qualified 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.
FLY ASH
This accumulates in the horizontal portion of an exhaust run. Though non- combustible, it may impede the normal exhaust flow. 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 fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all 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 & 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 confined 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.

MAINTENANCE

CHECK & CLEAN THE HOPPER
Check the hopper periodically to determine if there is any sawdust (fines) 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 1″ 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 the 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 followed by the 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 rope gasket using hightemperature 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 first fire of the heating season, check the outside area around the exhaust and air intake systems for obstructions. Clean and remove any fly 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 flowing (this can be done by pressing the “ON” button with the viewing door open). Vacuum out the hopper. Thoroughly clean the burn pot, and firebox. 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.

ERROR CODES & DISPLAY INDICATORS

DISPLAY INDICATORS
Several situations or events are indicated in normal operation by blinking display indicators or segments in the display:
Flashing On Indicator: This means that the heater is in the “Start Up” awaiting for the ignition procedure to complete.
Flashing Off Indicator: This indicates that the heater is in the “Shutdown” state waiting for the OFF button, or for a 15 minute period after the heater was turned off, or for the heater to cool down, or for the door to be closed.
Flashing Dash In Heat Range Display: This indicates that the heater is in the normal run mode and is ramping from the current heat range setting to the target heat range setting. Once the ramp is complete, the dash will stop flashing. For ramping from heat range 1 to 5, the default time is 12 minutes (with a 90 second ramp time).
Flashing Heat Range Value In “Heat Range” Display: For example, if the display is showing “Hr-3” and the `3′ is blinking, this indicates that the heater thermostat input is open and not calling for heat. While this is happening, the actual heat range value is 1 (low).
Flashing Automatic Mode Indicator: This indicates that the heater is in normal operation and is running in the automatic mode. However, either the Draft Fan or Auxiliary setting is manually configured.

Flashing Draft Fan Setting Indicator: This indicates that the heater is in normal operation and that the vacuum sensor detects a loss of pressure either because the door is open or because there is a negative pressure in the room with respect to the exhaust.
Flashing Aux Indicator: This indicates that the igniter is on during the lighting stage.
Quick (changes twice per second) Flashing Heat Range Setting Indicator: This indicates that the heater is in normal operation and that an over temperature condition exists causing the fuel to stop.
Slow (changes once per second) Flashing Heat Range Setting Indicator: This indicates that the heater is in a cutback condition in an attempt to prevent an over temperature shutdown.
FACTORY DEFAULTS
To return the control to its original factory default settings, press and hold the AUX UP and AUX DOWN buttons together for three seconds.
