VISIBLE SMOKE

The amount of visible smoke being produced can be an effective method of determining how efciently the

combustion process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture

leaving your stove. Learn to adjust the air settings of your specic unit to produce the smallest amount of visible

smoke. Wood that has not been seasoned properly and has a high wood moisture content will produce excess

visible smoke and burn poorly.

FUEL CONSIDERATIONS

Your pellet stove is designed to burn premium hardwood pellets that comply with Association of Pellet Fuel

Industries standards. (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 refueling and ash removal. Doing so could result in a house re.

SAFETY AND EPA COMPLIANCE

Your pellet stove has been approved for installation in the USA and Canada. It may also be installed in a

manufactured or mobile home. It has been safety tested and listed to ASTM E 1509-04, ULC-S627-00, ULC/ORD

C1482-90, and(UM) 84-HUD by INTERTEK Testing Services in Fairview, Oregon USA.

* Pellet size may effect the actual rate of fuel feed and burn times. Fuel feed rates may vary by as much as 20%.

Use PFI listed fuel for best results.

VENTING REQUIREMENTS

• Install vent at clearances specied by the vent manufacturer.

• Do not connect the pellet vent to a vent serving any other appliance or stove.

• Do not install a ue damper in the exhaust venting system of this unit.

• The following installation guidelines must be followed to ensure conformity with both the safety listing of this

stove and to local building codes. Do not use makeshift methods or compromise in the installation.

MAXIMUM VENTING DISTANCE

Installation MUST include at least 3-feet of vertical pipe outside the home. This will create some natural draft to

reduce the possibility of smoke or odor during appliance shutdown and keep exhaust from causing a nuisance

or hazard by exposing people or shrubs to high temperatures. The maximum recommend vertical venting height

is 12-feet for 3-inch type “PL” vent. Total length of horizontal vent must not exceed 4-feet. This could cause back

pressure. Use no more than 180 degrees of elbows (two 90-degree elbows, or two 45-degree and one 90-degree

elbow, etc.) to maintain adequate draft.

IMPORTANCE OF PROPER DRAFT

Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your

chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too

much draft may cause excessive temperatures in the appliance. Inadequate draft may cause 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 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 y ash and to permit periodic cleaning

of the exhaust system. The clean-out tee must be installed at the base of the vertical section, not in horizontal

section. 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 on the inside and high temperature tape on the outside 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.

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.

IMPROPER INSTALLATION: The manufacturer will not be held responsible for damage caused by the

malfunction of a stove due to improper venting or installation. Call (800) 750-2723 and/or consult a

professional installer if you have any questions.

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 require 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 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 (3.66m),

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.

FIGURE 8

EXHAUST/INLET LOCATIONS

OUTSIDE AIR SUPPLY (OPTIONAL, UNLESS INSTALLING IN A MOBILE HOME) OR AN AIRTIGHT HOME

Depending on your location and home construction, outside air may be necessary for optimal performance.

Metal pipe (solid or exible) must be used for the outside air installation. PVC pipe is NOT approved and should

NEVER be used.

A wind shield over the termination of the outside air pipe or a 90-degree elbow or bend away from the prevailing

winds MUST be used when an outside air pipe is installed through the side of a building. The outside air termination

MUST be at least 1ft (0.305m) away from the exhaust system termination.

The outside air pipe on your heater is 2” (50.8mm) OD. The outside air connecting pipe must be at least 2”

(50.8mm) ID. The outside air connection used MUST NOT restrict the amount of air available to your heater. The

outside air connecting pipe must be as short and free of bends as possible, and it must t over, not inside, the

outside air connection to the heater.

SPECIAL MOBILE HOME REQUIREMENTS

• WARNING! - Do not install in a sleeping room

• CAUTION! - The structural integrity of the mobile home oor, wall, and ceiling/roof must be maintained.

• A working smoke detector must be installed in the same room as this product.

• It must be installed at least 15 feet (4,57 m) from the appliance in order to prevent undue triggering of the

detector when reloading.

In addition to the previously detailed installation requirements, mobile home installations must meet the following

requirements:

• The heater must be permanently bolted to the oor through provided holes in the base.

• 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 in.(914mm) above the roof line of the

mobile home and must be installed using a UL listed 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 your dealer for purchasing or call customer

service.

• Check with your local building ofcials as other codes may apply.

PANEL CONTROLS

The blowers and automatic fuel supply are controlled from a panel on the left

side of the appliance. The control panel functions are as follows:

A. ON/OFF SWITCH

• When pushed the stove will automatically ignite. No other restarter is

necessary. The igniter will stay on for at least 10 and up to 15 minutes,

depending on when Proof of Fire is reached. The re should start in about 5

minutes.

• the green light located above the On/Off button (in the On/Off box) will ash

during the ignition start-up period.

• The Heat Level Advance is inoperable during the ignition start period. When

the green light continuously stays on, the Heat Level Advance can be

adjusted to achieve the desired heat output.

To manually ignite in case of ignitor failure. Place a handful of pellets in the burnpot.

Add starter gel for pellet stoves, ignite, close door, turn the unit on.. Replace the

ignitor as soon as possible.

NOTE: If the stove has been shut off, and you want to re-start it while it is still warm,

the “on/off” button must be held down for 2 seconds.

B. B. FUEL FEED SWITCH

• When the “Fuel Feed” button is pushed and held down, the stove will feed

pellets continuously into the burn pot.

• While the stove’s auger system is feeding pellets, the green light (in the “Fuel

Feed” box) will be on.

CAUTION: DO NOT USE THIS CONTROL DURING NORMAL OPERATION BECAUSE IT

COULD SMOTHER THE FIRE AND LEAD TO A DANGEROUS SITUATION.

C. HIGH FAN SWITCH

• The room air fan speed varies directly with the feed rate. The “HIGH FAN”

switch overrides this variable speed function. It will set the room air blower

speed to high at any feed rate setting.

• When the “HIGH FAN” button is pushed, the room air fan will switch to its highest setting.

• When this button is pushed again, the room air fan will return to its original setting based on the Heat Level

Advance setting.

D. RESET TRIM

Different size and quality pellet fuel may require adjustment of the “1” feed setting on the Heat Level Advance

bar graph. This is usually a one-time adjustment based on the fuel you are using. The “RESET TRIM” button when

adjusted will allow for 3 different feed rate settings for the #1 feed setting only. To adjust simply push the “RESET

TRIM” button while the stove is operating at setting “1” and watch the bar graph.

• When the “1” & “3” lights are illuminated on the bar graph the low feed rate is at its “lowest” setting.

(Approx. 0.9 pounds per hour)

• When the “1” light is illuminated on the bar graph, the low feed rate is at its “normal” setting.

• When the “1” & “4” lights are illuminated on the bar graph, the low feed rate is at its “highest” setting.

NOTE: When the stove is set on “1” the “reset trim” values will be shown on the Heat Level Advance bar graph.

For example if the Reset Trim is set to its lowest setting every time the stove is set to low the “1” and “3” lights will

be illuminated on the bar graph.

E. HEAT LEVEL ADVANCE

• This button, when pushed, will set the pellet feed rate, hence the heat output of your stove. The levels of

heat output will incrementally change on the bar graph starting from level “1” to “4”.

NOTE: When dropping 3 or more heat level settings (4 to 1,) push the ‘High Fan’ button and allow the room air

fan to run at that setting for at least 5 minutes to prevent the stove from tripping the high temp thermodisc. If the

high temp thermodisc does trip, see “SAFETY FEATURES”.

Control Panel

-11-

• DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE - Never use gasoline, gasoline-type lantern fuel,

kerosene, charcoal lighter uid, or similar liquids to start or “freshen up” a re in this stove. Keep all such

liquids well away from the stove while it is in use.

• HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKINS

BURNS.

• DO NOT USE GRATES OR ELEVATE THE FIRE. BUILD FIRE DIRECTLY ON HEARTH.

• DO NOT OVERFIRE - IF HEATER OR CHIMNEY CONNECTOR GLOWS, YOU ARE OVERFIRING.

• Attempts to achieve heat output rates that exceed heater design specications can result in permanent

damage to the heater.

This heater is designed to burn only PFI Premium grade pellets. This appliance can also burn pellets rated as

standard after May 16, 2015

DO NOT BURN:

1. Garbage;

2. Lawn clippings or yard waste;

3. Materials containing rubber, including tires;

4. Materials containing plastic;

5. Waste petroleum products, paints or paint thinners,

or asphalt products;

6. Materials containing asbestos;

7. Construction or demolition debris;

8. Railroad ties or pressure-treated wood;

9. Manure or animal remains;

10. Salt water driftwood or other previously salt water

saturated materials;

11. Unseasoned wood; or

12. Paper products, cardboard, plywood, or

particleboard. The prohibition against burning

these materials does not prohibit the use of re

starters made from paper, cardboard, saw dust,

wax and similar substances for the purpose of

starting a re in an affected wood heater.

Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.

PROPER FUEL

THIS STOVE IS APPROVED FOR BURNING PELLETIZED WOOD FUEL ONLY! Factory-approved pellets are those 1/4”

or 5/16” in diameter and not over 1” long. Longer or thicker pellets sometimes bridge the auger ights, which

prevents proper pellet feed. Burning wood in forms other than pellets is not permitted. It will violate the building

codes for which the stove has been approved and will void all warranties. The design incorporates automatic

feed of the pellet fuel into the re at a carefully prescribed rate. Any additional fuel introduced by hand will not

increase heat output but may seriously impair the stoves performance by generating considerable smoke. Do

not burn wet pellets. The stove’s performance depends heavily on the quality of your pellet fuel. Avoid pellet

brands that display these characteristics:

a. 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.

b. Binders – Some pellets are produced with materials to hold the together or “bind” them.

c. 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. United States Stove Co. cannot accept responsibility

for damage due to poor quality pellets.

Medium - Low Heat setting 2, air slide set at 0.365” from full closed

Medium - High Heat setting 3, air slide set at 1” from full closed

High Heat setting 4, air slide fully open

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.

NOTE: The 5520 Hopper can hold up to 120 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. If it is the rst time you have started the unit, or

anytime the hopper has been emptied of pellets, it will be necessary to prime the auger. In order to prime the

auger press and hold the fuel feed button after starting the unit. Keep fuel feed button depressed until pellets

begin to fall into the burn pot, then release the fuel feed button and allow the unit to operate normally.

During the start up period:

1. DO NOT open the viewing door.

2. DO NOT open the damper more than 1/4”.

3. DO NOT add pellets to the burn pot by hand.

4. DO NOT use the Fuel Feed button (unless you are priming the auger after running out of pellets). A dangerous

condition could result.

NOTE: During the rst few res, your stove will emit an odor as the high temperature paint cures or becomes

seasoned to the metal. Maintaining smaller res will minimize this. Avoid placing items on stove top during this

period because paint could be affected.

THE AUTOMATIC FIRESTARTER

a. Fill hopper and clean burn pot.

b. Press “On/Off” button. Make sure light is on.

c. The damper should be completely closed or open no more than 1/4” 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”)

d. Adjust feed rate to desired setting by pressing “Heat Level Advance” button.

If re doesn’t start in 15 minutes, press “On/Off”, wait a few minutes, clear the burn pot, and start procedure

again.

DAMPER CONTROL

The damper control rod on the stove’s lower left side 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

pulling the damper out slightly. A “blow torch” re can be improved by pushing the damper in a bit.

As a general rule, on lower feed rate settings, the damper should be in farther. On higher feed rates, the damper

should be more open. Through trial and error, you will nd the best setting. Consult your dealer if you need help.

NOTE: On “1”, damper should be either completely closed or out approximately 1/8” to 1/4”. If damper is out

too far, it can cause the re to go out.

OPENING DOOR

If the door is opened while the stove is in operation it must be closed within 30 seconds or the stove will shut

down. If the stove shuts down push the “On/Off” button to re-start your stove.

Operation

-13-

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.

RE-STARTING A WARM STOVE

If the stove has been shut off, and you want to re-start it while it is still warm, the “on/off” button must be held

down for 2 seconds.

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 to 45 minutes.

After the stove components stop running the “On/Off” and the BAR GRAPH lights stay on for 10 minutes. After the

10 minutes the “3” light on the bar graph will ash and the “On/Off” light will go off. To restart, rell hopper and

press “Fuel Feed” button until pellets begin to fall into burn pot. Press “On/Off” button.

REFUELING

• The hopper and stove top will be hot during operation; therefore, you should always use some type of hand

protection when refueling your stove.

• Never place your hand near the auger while the stove is in operation.

We recommend that you not let the hopper drop below ¼ full.

KEEP HOPPER LID CLOSED AT ALL TIMES EXCEPT WHEN REFILLING. DO NOT OVERFILL HOPPER.

SHUTDOWN PROCEDURE

Turning your stove off is a matter of pressing the “On/Off” control panel switch. The red light will go out. The

blowers will continue to operate until internal rebox temperatures have fallen to a preset level.

SAFETY FEATURES

a. Your stove is equipped with a high temperature thermodisc. This safety switch has two functions.

1. To recognize an overheat situation in the stove and shut down the fuel feed or auger system.

2. 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.

b. 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. Close the door and press “On/Off” button to continue operation

of your 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: Never shut down this unit by unplugging it from the power source.

Operation

OPTIONAL THERMOSTAT

A optional thermostat may help you maintain a constant

house temperature automatically. A millivolt thermostat is

required. A xed wall mount or hand held model can be

used. The control panel can be set up two ways to operate

your stove in thermostat mode.

THERMOSTAT INSTALLATION

• A MILLIVOLT NON-PROGRAMMABLE THERMOSTAT IS

REQUIRED.

• Unplug stove from power outlet.

• Remove control board from stove.

• The two thermostat wires connect to the terminal block

on the lower left side of the back of the control board.

• Insert the wires in the terminal side and tighten the two

screws.

MODES

TO SWITCH BETWEEN ANY OF THE THREE MODES THE STOVE

MUST BE SHUT OFF, THE NEW MODE SELECTED, AND THE

STOVE RESTARTED.

MANUAL MODE

• USE THIS MODE EXCLUSIVELY IF YOU DO NOT CONNECT

AN OPTIONAL THERMOSTAT.

• In this mode the stove will operate only from the control

panel as detailed in the “OPERATION” section of this

owner’s manual.

HIGH/LOW THERMOSTAT MODE

• USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT.

• When engaged in this mode the stove will

automatically switch between two settings. When

warm enough, it will switch to the #1 or low setting. The

room air blower will also slow to its lowest speed.

• The Heat Level Advance setting on the bar graph will

stay where it was initially set. When the house cools

below the thermostat setting, the stove will switch to the feed rate of the heat level advance setting.

ON/OFF THERMOSTAT MODE (IGNITOR LIFE WILL BE CUT DOWN IN THIS MODE)

• USE THIS MODE ONLY IF YOU CONNECT A THERMOSTAT.

• In this mode, when the home is warm enough the stove will shut off. The fans will continue to run until the

stove cools.

• When the home cools below the thermostat setting, the stove will automatically restart and run at the last

feed rate setting.

NOTE: When in “high/low” or “on/off” thermostat mode –

• Do not operate the stove higher than the #3 setting.

• Set damper control rod approximately 1/4” to 1/2” out. This will vary depending on elevation and weather

conditions. Observe stoves operation and adjust damper as necessary.

Thermostat Installation

On/Off High/Low Manual

-15-

• Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.

• Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any

inspection, cleaning, or maintenance work.

• Never perform any inspections, cleaning, or maintenance on a hot stove.

• Do not operate stove with broken glass , leakage of ue gas may result.

• WARNING THE CHIMNEY AND CHIMNEY CONNECTOR MUST BE KEPT IN GOOD CONDITION AND CLEAN.

EXHAUST SYSTEM

Creosote Formation – When any wood is burned slowly, it produces tar and other organic vapors, which combine

with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney ue or a

newly started re or from a slow-burning re. As a result, creosote residue accumulates on the ue lining. When

ignited, this creosote makes an extremely hot re, which may damage the chimney or even destroy the house.

Despite their high efciency, pellet stoves can accumulate creosote under certain conditions.

Soot and Flyash: Formation and Need for Removal- The products of combustion will contain small particles of

yash. The yash will collect in the exhaust venting system and restrict the ow of the ue gases. Incomplete

combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some

soot formation which will collect in the exhaust venting system. The exhaust venting system should B e inspected

at least once every year to determine if cleaning is necessary.

Inspection and Removal – The chimney connector and chimney should be inspected annually or per ton of

pellets to determine if creosote or y ash build-up has occurred. If creosote has accumulated, it should be

removed to reduce the risk of a chimney re. Inspect the system at the stove connection and at the chimney

top. Cooler surfaces tend to build creosote deposits quicker, so it is important to check the chimney from the top

as well as from the bottom. The creosote should be removed with a brush specically designed for the type of

chimney in use. A quali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

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 two(2) plates on each side of the burn pot housing and clean out that rear chamber.

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.

ASH DISPOSAL

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 cinders have been thoroughly cooled. The container shall not be used for other trash or

waste disposal.

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 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 AND CLEAN THE HOPPER

Check the hopper periodically to determine if there is any sawdust or pellets that are sticking to the hopper

surface. Clean as needed.

DOOR AND GLASS GASKETS

Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have

frayed, broken, or compacted gaskets replaced by your authorized dealer. The glass gasket has a gap at the

bottom for the air wash. This unit’s door uses a 3/4” diameter rope gasket.

Maintenance

-16-

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 and housing as part of your fall start-up.

PAINTED SURFACES

Painted surfaces may be wiped down with a damp cloth. If scratches appear, or you wish to renew your paint,

contact your authorized dealer to obtain a can of suitable high-temperature paint.

GLASS - CLEANING, REMOVAL AND REPLACEMENT OF BROKEN DOOR GLASS

Cleaning - We recommend using a high quality glass cleaner. Should a build up 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 six(6) 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, careful not to overtighten 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.

Maintenance

-17-

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 the diagrams 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.

Trouble Shooting Guide

STOVE SHUTS OFF AND THE #2 LIGHT FLASHES

Possible Causes: Possible Remedies: (Unplug stove rst when possible)

1. 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.

2. The air inlet, burnpot, interior combustion air

chambers, combustion blower, or exhaust pipe are

blocked with ash or foreign material.

Follow all cleaning procedures in the maintenance section of

the owner’s manual.

3. The rebox is not properly sealed.

Make sure the door is closed and that the gasket is in good

shape. If the ash door has a latch, make sure the ash door is

properly latched and the gasket is sealing good. If the stove

has just a small hole for the ashes to fall through under the

burnpot, make sure the slider plate is in place to seal off the

rebox oor.

4. Vent pipe is incorrectly installed.

Check to make sure vent pipe installation meets criteria in

owner’s manual.

5. The airow switch wire connections are bad.

Check the connectors that attach the gray wires to the air

switch.

6. The gray wires are pulled loose at the Molex

connector on the wiring harness.

Check to see if the gray wires are loose at the Molex

connector.

7. Combustion blower failure.

With the stove on, check to see if the combustion blower is

running. If it is not, you will need to check for power going to

the combustion blower. It should be a full current. If there is

power, the blower is bad. If there is not, see #8.

8. 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.

9. 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.

10. Air switch has failed (very rare).

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.

-18-

STOVE SHUTS OFF AND THE #3 LIGHT FLASHES

Possible Causes Possible Remedies: (Unplug stove rst when possible)

1. The hopper is out of pellets. Rell the hopper.

2. The air damper is too far open for a low feed setting.

If burning on the low setting, you may need to close the

damper all the way (push the knob in so it touches the side of

the stove).

3. 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.

4. The burnpot holes are blocked. Remove the burnpot and thoroughly clean it.

5. The air inlet, the interior chambers, or exhaust system

has a partial blockage.

Follow all cleaning procedures in the maintenance section of

the owner’s manual.

6. The hopper safety switch has failed or hopper is open.

When operating the unit, be sure the hopper lid is closed so

that the hopper safety switch will activate. Check the wires

leading from the hopper safety switch to the control panel

and auger motor for secure connections. Use a continuity

tester to test the hopper safety switch; replace if necessary.

7. The auger shaft is jammed.

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 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.

8. 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.

9. The Proof of Fire (POF) thermodisc has malfunctioned.

Temporarily bypass the POF thermodisc by disconnecting the

two brown wires and connecting them with a short piece

of wire. Then plug the stove back in. 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.

10. The high limit thermodisc 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.

11. The fuse on the control board has blown.

Remove the control board. On the back there is one fuse. If

it appears to be bad, replace it with a 5 Amp, 125 Volt fuse.

Plug the stove back in and try to run the unit.

12. 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.

Trouble Shooting Guide

-19-

STOVE FEEDS PELLETS, BUT WILL NOT IGNITE

Possible Causes Possible Remedies: (Unplug stove 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 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 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 rebox.

Make sure that the air intake collar on the burnpot is touching

the rear wall of the 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 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. 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 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 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

-20-

STOVE WILL NOT FEED PELLETS, BUT FUEL FEED LIGHT COMES ON AS DESIGNED

Possible Causes Possible Remedies: (Unplug stove rst when possible)

1. Fuse on control board blew.

Remove the control board. On the back there is one fuse. If

it appears to be bad, replace it with a 5 Amp 125 Volt fuse.

Plug the stove back in and try to run the unit.

2. 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.

3. 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.

4. 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 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.

5. Loose wire or connector.

Check all wires and connectors that connector to the auger

motor, high limit switch, and the Molex connector.

6. 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 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. A battery backup may be used if rated at

least 1000W.

5. High limit switch is malfunctioning. If the other items check out OK, replace the high limit switch.
