9When installing your MagnuM Winchester (WIN) Corn/Biomass/Wood Pellet stove, particular attention
needs to be made in regards to fire protection. If the unit is not properly installed, a house fire may result.
For your safety, follow the installation and operation instructions provided, and if a question arises contact
local building or fire officials about restrictions and installation requirements in your area.
9Read the operations and fuel section of this manual before plugging in your unit.
9Always unplug the unit before attempting any service work.
9Do not connect the unit to a chimney flue already serving another appliance.
9When installing the chimney pipe to the unit, it is important to remember that the unit operates on a
negative pressure and the chimney on a positive pressure. All chimney connections, elbows and fittings
must be airtight. (Proper venting practices must be followed. Consult with a venting professional)
9Ashes must be disposed of in a metal container with a tight fitting lid.
9All minimum clearances to combustibles must be followed.
9The MagnuM Corn/Biomass/Wood Pellet Stove is tested for operation with wood pellets, with an ash
content of no more than 2% and Corn with a moisture content from 10-14 percent. It is recommended
that wood pellets with an ash content of 1% or less be used for efficient operation of this unit. Higher
ash content fuels will require additional maintenance and service. Also, for use with wood pellets,
cherry pits, olive pits or other pelletized Biomass fuel. Corn with 11-12 percent moisture is ideal.
9It is important to use fuel that is clean, dry and consistent. Make sure that your supplier is giving you
the same fuel each time that you purchase. It is recommended that you purchase your entire heating season
supply of fuel at one time so that the fuel will be the same.
9A voltage surge protector or ground fault outlet is required for this unit. The electrical component
warranty will be voided if surge protection is not installed before operating this unit.
9A grounded outlet must be provided with proper polarity. A constant 120 volt (12volt on DC
models), 60 cycles must be provided for proper operation or the warranty of this appliance will be
forfeited.
9Special attention needs to be taken to clean out the top heat exchangers of this unit on a regular
basis. The fly ash settles on the heat exchangers and must be cleaned off to keep the unit operating
properly. Check for plugging every two-four weeks or when needed.
9If unit is not operated for extended periods of time (like summer) unplug the unit and disconnect the
battery to assure long life of electrical components.

Technical Bulletin
Importance of Adequate Fresh Air
Every home is a slightly different situation and depending on the design of the air movement within
the home, might be easy to distribute heat or very difficult. If you have boiler heat or other non-
ducted central heating this becomes even more of a challenge as adequate circulation within the
home and proper make up air for combustion is lacking because of the design of your central
heating system.
When a forced-air system is put into a home that is not designed with proper circulatory patterns, it
might be necessary to add return air ducts or at least vents to get the air moving around the home.
Fresh air for the home and fresh air for combustion will have to be added or the stove or furnace
will burn dirty and efficiency will suffer.
Your dealer needs to assess the fresh air requirements for the home. At a minimum, there should be
a 6” or larger (this should be determined by figuring what the home requires) fresh air vent coming
in to a neutral part of the home to make sure that there is adequate fresh air to the home. Then the
3”make up air to the unit is required to be provided.
If the wood pellets are not burning correctly you need to address a few things. Are the wood pellets
wet or dirty? If they are, make sure that your wood pellets are cleaned (we have an excellent “E-
SIFTER” product that will do a great job) and below 15 percent moisture. 3-4 percent moisture is
ideal.
The most common cause of wood pellets not burning properly is contaminated air or negative
pressure in the home. It can be as simple as the air adjustment not set properly on the side of the
stove or it could be that there is a serious lacking of good quality air in the home caused by negative
pressure. If you have done any remodeling or if this is a newer home, it is a very real possibility
that this is happening. Most basements have negative pressure even if you feel that your home is
drafty. This is called the stack or chimney effect.
If there is a black coating of soot coming into the home it is caused by the reversal of the exhaust
that would normally exit the stove outside being drawn into the home by negative pressure or
improperly installed venting. Depending on your venting configuration this could be aggravated by
back drafts, high wind and cold chimneys.
Sometimes this also occurs if there is an intake for fresh air too close to the exhaust on the outside
of the home or other conditions causing the exhaust to be pulled back into the home.
The first indications of negative pressure affecting the stove occurs app. 3 days after the stove is lit.
The glass gets dirty very easy, the firepot might keep filling up even though you pull the air
adjustment out, and you notice that the venting fills up with soot rapidly. After a few days, the
exhaust can no longer adequately pull out all of the fly ash so it reverses and is pulled into the
home. This might happen through the venting if it is not sealed properly or it might come out when
you open the door for maintenance and also backwards through the air wash system.
This can be easily corrected by adding the fresh air for the home and also for the appliance. It is
imperative that you would have your dealer or installer check the unit out for proper operation to
make sure that there is nothing mechanical wrong with the appliance and then determine your need
for proper fresh air. Your dealer can contact the factory with any questions that he might have.

IMPORTANT: Proper installation of this stove is crucial for proper and safe operation. Installing this
product improperly may result in a house fire and/or personal injury. All applicable building codes for
your location must be followed. In areas where building codes require additional steps to the installation
of this product not included in this manual, the building codes will take precedent and must be followed.
Contact your local building inspector to obtain any necessary permits or inspection guidelines before
installing the product. (This appliance must be installed by a trained professional installer to assure
proper installation and warranty of this product) Warranty labor, parts failing due to improper
installation and shipping will not be covered if the unit is not installed by a trained installer.
9DISCONNECT THE POWER CORD BEFORE SERVICING THIS STOVE! A power
surge protector is required. The unit must be plugged in to a grounded 120 volt 60 Hz or a 12V
DC sealed battery power source. NEVER use an “unsealed” type battery, nor operate unit on a
battery without a 12 volt 4 ampere in-line fuse on a positive line.
9Always route the power cord away from the unit. Do not route cord in foot traffic areas. Do not
pinch cord under furniture. Do not add any additional length to the power cord.
9This product requires simple periodic maintenance for proper operation and long life of the stove.
Read and follow the maintenance schedule closely. Do not operate with the doors or hopper
open.
9The MagnuM Winchester stove models are designed, approved and tested to burn
corn/wood pellets and other Biomass fuels. The burning of other solid fuels such as cord wood
in this stove is not permitted. If you are burning fuels not approved for this appliance it will void
the warranty and no service/warranty will be allowed.
9The MagnuM models will burn high ash content fuels but will require additional
maintenance/cleaning.
9A working smoke detector must be installed in the same room as this product.
9It is recommended that a fire extinguisher “class a-b-c” be installed close to the appliance.
9Flammable or explosive liquids such as gasoline, naphtha or engine oil must NEVER be used in or
around this stove. These liquids must be stored well away from this stove as the open flame in the
burn chamber could ignite the fumes of such liquids. Do not burn garbage in this unit.
9According to HUD requirements, when installed in a mobile home, this stove must be grounded
directly to the steel chassis of the mobile home and bolted to the floor.
9This stove is not intended for use in commercial installations but can be used.
9The moving parts of this stove are propelled by high torque electric motors. The auger can cause
severe injury to body parts that may get near them. Keep all body parts away from the auger while
the stove is plugged into an electrical outlet. These moving parts may begin moving at any time
while the stove is plugged in.
9This unit must be installed on a non-combustible surface. Make sure that the unit is level.
9Do not attempt internal service to the unit when it is burning and or plugged into power.
9It is a good idea to burn the unit outside for a couple hours before installation to burn off any paint
or oil fumes. (Most resellers pre-burn the unit before you receive them, do not worry if your unit
looks like it has been burnt.)
IMPORTANT: It is the customer’s responsibility to make sure the MagnuM appliance is installed with the
proper make up air system and the home is checked for adequate fresh air so that the appliance does not
become the fresh air source for the home.
SAFETY STEPS

6
Unlike petroleum and natural gas products, solid fuels such as wood pellets create ash as the fuel is
burned. Even with the highly efficient flame your MagnuM stove will produce, the solid fuels used will
produce ash. This ash will have to be cleaned out of the stove from time to time. The cleaning procedure
will be discussed later in this manual. You can minimize the amount of cleaning required and maximize
the efficiency of your stove by maintaining the correct draft settings.
The draft setting on your stove may have to be changed from time to time to accommodate your specific
burning conditions. Proper draft setting will be discussed later in this manual. The point we wish to
make here is that your MagnuM stove, due to the nature of solid fuels, will require brief periodic
attention. Please do not expect to light your stove and walk away from it until you want to shut it off in
the spring. A few moments of adjustment and cleaning from time to time is an important part of burning
solid fuels.
The MagnuM stove has been designed to burn wood pellets that meet the Association of Pellet Fuel
Industries standards. Since these fuels vary greatly in quality and consistency, AES cannot be responsible
for damage done to your stove due to fuel problems. The following are guidelines to using and selecting
proper fuels for your stove.
SHELLED CORN (11-12 percent moisture recommended)
9Store your corn supply in a dry place and keep the bags or containers sealed to prevent your corn from
absorbing excess moisture. Test the moisture content periodically to maintain the proper dryness.
9Check your corn for foreign objects. Your stove warranty will not cover damage done to your
stove due to foreign objects in the fuel supply.
9Do not carry your corn supply over into the next heating season if possible unless properly
stored. If you carry over your corn supply make sure to check the corn for proper moisture content.
9DO NOT BURN “TREATED” SEED CORN IN YOUR STOVE. Seed corn is treated with
chemical pesticides that are harmful or fatal if swallowed; therefore, seed corn is dangerous to have in
the house, especially where children can reach it. Burning treated seed corn in your stove will void
the warranty and will destroy the exhaust system on the unit.
9Corn must be 14% or less moisture content. Wet corn will cause rapid plugging and deterioration
of the stove and exhaust system, lower the heat output and will void the product warranty.
9Corn must be cleaned and free from debris. Corn right from the field will often have stalks, sticks,
bolts and cob debris, which can plug the auger and/or cause damage to the auger and motor. Damage
caused by dirty corn and other foreign objects are not covered by the product warranty. Ask for clean
corn when you purchase it from your local corn supplier. Clean corn can be purchased in bulk or
bagged from most elevators, feed stores or even your local farmer.
ALWAYS ASK FOR CORN WITH 11-12% MOISTURE CONTENT.
9If you are having trouble finding clean Corn, contact your local MagnuM Dealer and ask them
to get you an “Energy Sifter” corn cleaning system. Cleaning your corn with the Energy Sifter
from American Energy Systems will assure clean corn and a more consistent burn rate. It is also
important to vacuum out your hopper once a month to assure trouble free auguring of the corn.
BURNING SOLID FUELS (shelled corn and wood pellets)

7
9There are many varieties of corn grown around the world. Each variety has unique characteristics
including the shape and size of the kernel. Your stove will burn more consistently with a small to
mid-size kernel corn. If the kernel size of the corn varies greatly or if you switch sources frequently,
you will get a less consistent burn, which will require more attention to the draft setting on your stove.
Therefore, purchasing corn from the same source will help achieve a more consistent burn. DO NOT
USE CORN WITH A HIGH WAX CONTENT!
WOOD PELLETS
9Be consistent in your wood pellet fuel supplier. Wood pellets will vary in content and burn
characteristics from supplier to supplier. A consistent supply of wood pellets will require fewer
adjustments to the draft of the stove.
9Check your wood pellets for foreign objects. Your stove warranty will not cover damage done to your
stove due to foreign objects in the fuel supply.
9Store your wood pellets in a dry place to prevent them from absorbing excess moisture.
9Vacuum the hopper out after every 6-7 bags to eliminate buildup of sawdust. More often if the wood
pellets are poor quality. If sawdust is a problem you will have to screen each bag of fuel for a
consistent feed.
9Wood pellets vary from supplier to supplier in ash content from less than 1% to 3% or more. Low ash
content pellets will allow you to burn the stove longer between cleanings. Only wood pellets
manufactured to the Association of Pellet Fuel Industries (A.P.F.I.) standard for residential pellet fuels
are recommended. Look for A.P.F.I. registration number on the back of pellets. Consult your local
MagnuM reseller for more information on approved wood pellet fuel.
9It is strongly recommended not to keep a supply of wood pellets over the summer months. Moisture
will build up and cause problems in the fall with your appliance operation. Make sure that your
supplier is not selling you left over fuel or fuel that has been out in the rain.
When you receive your MagnuM Corn/Biomass/Wood Pellet Stove, Pedestal unit, Leg unit or
Fireplace Insert, be careful to inspect all parts and components to make sure that nothing was
damaged or lost in shipment. If there was shipping damage, be sure to report it to your MagnuM
reseller, or the shipping company that delivered your unit. Freight damage claims must be made to
the Freight Company immediately. If parts are missing contact your local MagnuM reseller or
contact the factory right away. Your satisfaction is our top priority.
To uncrate your MagnuM appliance:
1) Cut the banding straps and open the carton lid. The carton is stapled to the wood pallet so it will be
necessary to pull the cardboard loose from the pallet. Remove the crating box carefully lifting up over
the top of the unit. Be careful not to scratch the unit with the staples. Remove the wood blocks and
plastic. We strongly urge you to recycle the packaging materials to help protect the environment.
UNPACKING YOUR MAGNUM CORN/BIOMASS/WOOD PELLET UNIT

8
The Pedestal unit comes completely assembled, the Insert comes with the shroud packaged separately and
the Leg unit comes with the legs packaged in the hopper.
The installation of the Insert shroud is shown later in the installation manual. Make sure that the shroud is
with the unit when you get it.
The following diagram will show how to install the legs on the Leg Unit. The legs are wrapped up and
packaged in the hopper. Unpack the legs and get the four (4) nuts out of the hardware bag.
Tip the unit back so that you can get the leg onto the bolt that is sticking down in each corner of the
bottom of the base. Be sure to have someone helping hold the unit while you are attaching the leg. The
casting could break if bound or dropped.
NOTE: It is best to attach the legs on one side first and then lift the unit up level to attach the other
side. You can also attach the legs on the back two corners first and then the front.
Place the ¼” nut on the bolt that is located on the base of the unit and attach the leg to the bolt. Swing the
leg so that the foot of the leg is parallel with the 45-deg. angle of the front of the unit. Align the back leg
to match the front leg.
Be careful not to bind the leg when bolting onto the unit so that it does not break. The legs are designed
to face at a 45 degree angle so that they will face in the same direction as the slanted side of the face.
When the legs are bolted on and positioned where you like them, tighten the four (4) nuts. Make sure not
to over tighten the nuts and twist them off.

10
It is recommended that only an authorized MagnuM installer install your wood pellet stove. The following installation
guidelines must be followed to ensure conformity with both the safety listing of this stove and to local building codes.
9A listed 3” or 4” type “PL” pellet vent exhaust system must be used for FREESTANDING installation and attached to the
pipe connector provided on the back of the stove. Use a 3” to 4” adapter for 4” pipe. A cap must be used at the
termination of type “L” vent chimneys.
9Do 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 closed area, or any location that can build up a concentration of fumes such as a stairwell,
covered breezeway, etc.
9Vent surfaces can get hot enough to cause burns if touched by children. Non-combustible shielding or guards may be
required. Do not install a flue damper in the exhaust vent of this unit.
9Termination must exhaust above air inlet elevation. It is recommended that at least 3 ft. of vertical pipe be installed
when the appliance is vented directly through a wall or in a basement. 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. In any case, the safest and preferred venting method is to extend the vent
through the roof. Do not connect this unit to a chimney flue serving another appliance.
9Distance from doors and windows, gravity or ventilation air inlet into building:
Not less that 4 ft. / 1.2 m below, 4 ft. / 1.2 m horizontally from, 1 ft. / 305 mm above (This does not apply if the
windows are non-opening or have been fixed so they cannot open.)
9Distance from bottom of termination and grade – 1 ft. / 305 mm minimum. This is conditional upon the plants and nature
of grade surface. The exhaust gases are not hot enough to ignite grass, plants or shrubs located in the vicinity of the
termination. The grade surface must not be a lawn. Distance from bottom of termination and public walkway is 7ft. /2.1m
minimum.
9Distance to combustible materials – 2 ft. / 610 mm. This includes adjacent building, fences, protruding parts of the
structure, roof overhang, plants and shrubs, etc.
9It is recommended that a single or double clean-out “tee”, for cleaning the vent in both directions, be installed at every 90-
degree junction to enable collection of fly ash and to permit periodic cleaning of the exhaust system. 90-degree elbows
accumulate fly ash and soot, thereby reducing exhaust flow and performance of the stove.
9Total length of horizontal vent must not exceed 10 feet / 3,000 mm. All joints in the vent system must be fastened by at
least three (3) screws, and all joints must be sealed with high temp RTVsilicone sealer to be airtight.
9A 3” inch single-wall, stainless steel flexible or rigid exhaust pipe should be used for INSERT installations and must be
attached to the stove with a single-wall, stainless steel “tee” with a clean-out cap. The stainless steel “tee” should be
inclined at 45-degrees to enable the vent to be centered on the stove and allow the “tee” to be cleaned without removing
the stove (see diagram 11.1).
9When venting into an existing masonry or factory built chimney, the chimney must be cleaned, with all creosote removed.
The chimney must be a type suited for solid fuel. WARNING: The chimney and the chimney connections must be kept
clean and in good condition.
9The “PL” venting or single wall stainless exhaust system must be installed so as to be GAS TIGHT! The vent
manufacturer’s installation procedures must be followed. In addition, pipe connections, joints and all pipe seams within
the home should be sealed with high temperature RTV silicone sealer.
9If an insert is to be installed into an unlined masonry chimney, it is recommended that a 3” or 4” inch stainless steel pipe
be extended to the top of the existing chimney. The top of the existing chimney should be sealed with a steel plate (see
diagram 11.2).
GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN

11
GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN, CONT……
To determine whether a 3” or 4” inch exhaust system should be used, follow the guidelines below:
1) Determine the “equivalent pipe length” for each component used according to the comparison chart
below. Add the “equivalent pipe length” of all components to get the “total equivalent pipe length”.
2) Determine the altitude at which you are installing the stove.
3) Cross-reference the “total equivalent pipe length” and the altitude using the graph below.
NOTE: The “total equivalent pipe length” should not exceed 30’ feet.
Diagram 11.1
Component Equivalent Length Equivalent Pipe Length
Horizontal Straight Pipe Actual Length in ft. x 1.0 Horizontal Pipe = 1 x (2+1) = 3 ft.
Vertical Straight Pipe Actual Length in ft. x 0.5 Vertical Pipe = 0.5 x 8 = 4 ft.
900Elbow or Tee 5.0 feet 90 Degree Tee = 2 x 5 = 10 ft.
450Elbow 3.0 feet 45 Degree Tee = 1 x 3 = 3 ft.
TOTAL = 20 ft.
NOTE: These are guidelines only. Proper venting is accomplished by design and common sense. In most
installations 3” inch diameter venting is adequate. If it does not vent properly you will have to change it to
4” inch.

OUTSIDE MAKE-UP AIR FOR COMBUSTION IS REQUIRED ON ALL INSTALLATIONS
1) For FREESTANDING installations with horizontal through-the-wall exhaust, it is REQUIRED that the stove
combustion air intake be connected to a fresh air intake outside. If the home is newer or has been tightly
insulated it is imperative to the operation of the unit to install outside combustion air. If you do not, then an
additional 6” inch intake into the furnace room in the basement is required.
2) For INSERT installations into an existing fireplace, or FREESTANDING installations with a vertical exhaust,
outside air connection is required. It is not recommended to exit the fresh air intake out the top of the chimney.
3) Connection to outside the house is REQUIRED for all installations.
IMPORTANT: It is the customer’s responsibility to make sure that there is adequate fresh air to the home
so that the MagnuM appliance does not become the fresh air source.
4) Only non-combustible piping 3” inches in diameter is approved to use for outside air connections (straight or
flexible). PVC pipe is NOT approved and should NEVER be used.
5) If the air inlet is connected to the outside, it MUST be terminated with a vertical 90-degree bend (down) or with
a wind hood. Failure to do so could result in a burn back during high winds blowing directly up the air inlet
during a simultaneous power failure (see diagram above).
6) It is important not to terminate the inlet of the fresh air intake too close to the venting outlet for the exhaust. It
is recommended that the inlet for the fresh air is a minimum of 3’ to 5’ feet away from the venting outlet and at
least 1’-2’ feet below.
7) Blockage, excessive length, or bends in the air intake pipe will starve the stove of combustion air. A 90-degree
bend is equivalent in restriction to approximately 30” inches of straight inlet pipe.

INSTALLATION PRECAUTIONS
CAUTION: Do not install this appliance in any manner other than as described in this manual. If you
have any questions about properly venting or installing your MagnuM corn/biomass/wood pellet stove,
please contact your dealer or American Energy Systems, Inc. for information.
NOTE: THIS STOVE MUST BE BURN TESTED OUTSIDE IN A WELL VENTILATED AREA
FOR AT LEAST FOUR (4) HOURS. THIS WILL CURE THE PAINT AND SEASON THE
STOVE METAL. SMOKING AND STEAMING IS NORMAL DURING THE CURING
PROCESS, AND MAY CONTINUE DURING THE FIRST FEW TIMES THE STOVE IS USED.
The ONLY authorized exhaust vent pipe for this appliance is 3” or 4” inch listed Type PL pellet vent
pipe, designed for use with pellet stoves. This stove may be connected to an existing factory-built
chimney using pellet vent pipe as a connector, and a 3”-4”, 3”-6”, or 3”-8” PELLET VENT to
CHIMNEY ADAPTER. Follow the pellet vent pipe manufacture’s instructions for the installation of the
vent pipe being used. (See “Existing Vertical Installation”).
As you plan your installation, consider the following:
-The stove should be placed as central in the home as possible. Consider safety, convenience,
traffic flow and the fact that the stove will need a venting system and fresh air to the outside of the
home.
-Before drilling or cutting holes, select the location of the appliance. Determine where the ceiling
rafters, wall studs or floor joists are located before making any large holes as the appliance may
have to be moved.
-Care must be taken to maintain minimum clearances to combustibles as per local building codes,
fire codes, and the safety listing tag on the inside hopper lid.
-An outside air source must be connected to the stove and can be brought in through the sidewall
or vented crawl space. Flexible or rigid pipe should be used and will connect to the adaptor on the
back of the stove. (See air inlet location under the CLEARANCE section of this manual)
-Place the stove where you will enjoy watching the fire along with getting the best heat distribution
possible. Locating the stove in a closed room will not allow the unit to perform properly.
Installing the stove in an un-insulated area will also not allow the stove to heat the home properly.
-If the home was not designed with proper heat circulation, the stove will not perform properly.
Make sure that the installer looks at the entire home as a unit when installing your MagnuM
appliance. Make sure that there is adequate cold air returns to pull the heat to adjoining rooms.
DO NOT CONNECT THIS STOVE TO A CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.
DO NOT USE SINGLE WALL PIPE FOR ANY INSTALLATION.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
THIS EXHAUST SYSTEM IS PRESSURIZED.
Electrical power is 120 volt-60 Hz. The stove is provided with a six foot grounded electrical cord, and
should be connected to a standard 3 prong 120 volt, 60 Hz electrical outlet. (Make sure you have a surge
protector installed.) Do not route the cord in front of, or under the stove.
NOTE: A MAJOR CAUSE OF VENT RELATED FIRES IS FAILURE TO MAINTAIN
REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE MATERIAL. PLEASE
FOLLOW THE VENT PIPE MANUFACTURERS INSTRUCTIONS AND LOCAL BUILDING
CODES FOR THE PROPER CLEARANCES TO COMBUSTIBLES REQUIRED FOR THE
INSTALLATION OF THE VENT PIPE BEING USED.

VENT TERMINATION GENERAL INSTRUCTIONS
NOTE: The following are general instructions for installing this appliance.
THE PELLET VENT MANUFACTURER’S INSTRUCTIONS SHOULD BE
FOLLOWED FOR THE VENT PIPE BEING USED. USE ONLY 3” or 4” INCH
LISTED TYPE PL PELLET VENT PIPE.
WARNING: Shut off all electrical power to the wall or room where the appliance is going to be installed
before cutting any holes. Be careful not to drill or cut into any water lines or electrical wiring as water
damage or electrical fire may result.
Upon determining the best location for your new appliance, maintain at least the minimum allowable clearances.
Line up a plumb bob to the flue collar on the stove with the location for the hole in the wall or ceiling before
drilling or cutting any holes. (See rear exhaust and air inlet locations under the CLEARANCE section of this
manual.) Be sure to allow for any stove pad that you will be placing underneath the unit.
Prepare the vent pipe for painting (if you are painting the venting) by wiping down with straight vinegar. Rinse
vinegar off with clean water and allow the pipe to dry. Use high temperature paint as directed by the manufacturer
(the standard paint is Stove Bright Metallic Black). Let the paint dry for a couple hours before assembling.
Drill and enlarge the hole as required for installation of the wall thimble, vent pipe and components per the pellet
vent manufacturer’s instructions.
Connect the pipe and lock the joints as directed by the pellet vent manufacturer, and secure the vent pipe to the flue
collar on the back of the stove. Add a small bead of RTV high temperature silicone around the outside edge of the
flue collar prior to securing the vent pipe. Drill and attach the vent pipe to the flue collar with sheet metal screws.
Alternate (preferred) method: Attach the approved PL pipe adaptor on the back of the exhaust pipe located on the
rear of the appliance, secure with a 3” hose clamp and then attach all venting to the pipe adaptor.
Do not terminate the vent in any enclosed or semi-enclosed area, such as a carport, garage, attic, crawl space, under
a sun deck or porch, in a narrow walkway or closely fenced area, stairway, covered breezeway, or any other
location which can build up a concentration of flue gases.
Vent surfaces can become hot enough to cause burns if touched. Non-combustible shielding or guards may be
required.
Note: Make sure that you leave adequate clearance between the back of the unit and the wall to allow for proper
cleaning, servicing, and for when you open the hopper lid, that it does not hit the wall. It is recommended that you
leave 4”-6” inches of clearance between the appliance and the back wall of the home.
NOTE: THE VENT PIPE SHOULD BE INSPECTED FREQUENTLY TO VERIFY THE INTEGRITY OF
THE VENTING SYSTEM AND TO INSURE THAT NO OBSTRUCTIONS OR BUILD-UP EXIST
WITHIN THE VENT PIPE. FAILURE TO INSPECT THE VENT PIPE CAN CAUSE A MALFUNCTION
OR HAZARDOUS OPERATION OF THE STOVE.
