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. Excessive positive pressure in the home can also cause problems such as over firing.
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.

AVENT TECHNICAL DATA
ESTIMATED FUEL FEED RATE CHART
The fuel feed rates shown can vary as much as 30-50% depending on fuel quality.
WOOD PELLETS: Fuel consumption will vary depending on fuel size
Low fuel setting 16 ounces per hour 2.5 ounces in a 10 minute test
Medium fuel setting 24 ounces per hour 4 ounces in a 10 minute test
High 38 ounces per hour 6.4 ounces in a 10 minute test
These fuel consumption feed rates are an approximation. Each unit will vary with the type and size of
the fuel that is being burnt. The most important feed rates to check would be the # 1 setting and the
High setting to make sure that the low and high feeds are proper for the unit. If the feed rates are
drastically different contact your local dealer for circuit board factory adjustments. Do not get alarmed
if the feed rates are not the same as shown. As long as the low fire will stay lit and the high fire does
not overheat the unit and shut it down the unit is performing as it should.
The unit is designed to adapt to different size fuels and consumption circumstances.
If you are experiencing different feed rates than shown you will need to set the fuel feed rate on a lower
or higher setting to adjust for the differences in the fuel feed rate. The size and flow characteristics of
wood pellets vary from year to year and that alone will change the heat output of the unit. There is a
fine tune adjustment that the Reseller can make to the circuit board if the low fire will not stay lit or is
burning too hot. You will need to contact your local Reseller for this adjustment.
It is recommended that when the unit is first installed in the customer’s home that the unit be fired and
run for over an hour to see if the air adjustment is right for the fuel. Making the proper air adjustment
and making sure that proper outside air has been provided will allow the unit to perform properly.
The Avent is certified to burn premium quality wood pellets. Check with your local Reseller before
burning fuels not approved.
NOTE: The factory will not pay warranty service calls on problems that have come up on the
unit when the proper fuel, combustion air requirements and air adjustments have not been
checked. tdocbeff

looks like it has been burnt)
IMPORTANT: It is the customer’s responsibility to make sure the Reliant 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

7
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 Avent Wood Pellet 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 Avent Wood Pellet 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 Avent Wood Pellet 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.
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 Avent Wood Pellet reseller for more information on approved wood pellet fuel.
9Do not place or store any fuel within the space heater installation clearances or within the space
required for filling the fuel hopper and ash removal. It 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.
BURNING SOLID FUELS (wood pellets)

When you receive your Avent Wood Pellet Stove 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 Avent Wood Pellet 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
Avent Wood Pellet reseller or contact the factory right away. Your satisfaction is our top priority.
To uncrate your Avent Wood Pellet Stove:
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.
The Avent Wood Pellet Freestanding Stove may be installed on a combustible floor, with proper floor
protection, or on a masonry hearth. The hearth or non-combustible floor protector must extend a
minimum of (6) six inches (152mm) in front of the unit and beyond each side of the fuel loading and ash
Removal openings.
The stove must be installed with the following minimum clearances to side and back wall combustible
materials. NOTE: These are minimum clearances to combustible walls established by the testing lab.
The amount of room needed on the left side of the unit to access the electrical panel is (6) six inches.

It is recommended that only an authorized Avent Wood Pellet 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 top 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. Existing approved 4, 6 and 8” wood stove pipe may be used with adaptors to 3 inch pellet vent
pipe as shown in the installation instructions. The pipe adaptors must be provided by the venting manufacturer.
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 required that at least 5 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.

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 900
junction to enable collection of fly ash and to permit periodic cleaning of the exhaust system. 900 elbows accumulate fly
ash and soot thereby reducing exhaust flow and performance of the stove.
9Total length of horizontal vent must not exceed 36” (3 ft.) / 915 mm. 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.
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” vent 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. Single wall venting can only be used within the dwelling.
9A minimum of 3 feet/915mm horizontally from the center line of any regulator/meter assembly
9A minimum of 3 feet/915mm from any non mechanical air supply inlet to the building
9A minimum of 6 feet/1830mm from any mechanical air supply inlet to the building
NOTE: Local building codes or regulations may require different clearances.
Special note for Canadian Installations:
Where the venting may pass through a wall, or partition of combustible materials, the installation shall
conform to CAN/CSA-B365. The wall thimble shall be properly sealed with Hi-Temperature silicone to
prevent any moisture or vapor from building up. Make sure that there are no air leaks.
Clearances to venting and also clearances to combustibles for the appliance can only be reduced by means
approved by the regulatory authority.
EXHAUST VENTING SYSTEM PRECAUTIONS:
Soot and Flyash: Formation and need for removal- The products of combustion will contain small particles
of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue 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 be inspected at least once every year to determine if cleaning is necessary. It is recommended to
check the venting system monthly to assure proper operation of the appliance.

11
GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN, CONT……
To determine whether a 3” or 4” 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 20 feet.
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”.

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) Connection to outside the house is REQUIRED for mobile home installations.
3) The outside air tubing must be a minimum of 3” inside diameter. It is recommended that the tubing
be non-combustible materials but is not required.
4) 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).
5) It is important not to terminate the inlet of the fresh air intake too close to the venting outlet for the
smoke. It is recommended that the inlet for the fresh air is a minimum of 3 feet away from the venting
outlet and at least 1-2 feet below.
6) 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.

ALCOVE INSTALLATION REQUIREMENTS
The Avent Wood Pellet is approved for the standard alcove height of 56 inches, or for a reduced alcove
height with a minimum of 14 inches from the top of the stove (clearance for opening top lids). The
maximum alcove depth is 36 inches and the listed side clearances are a minimum of 4 inch. The 14”
clearance is only needed for opening the back lid.
The stove is approved for limited horizontal and vertical exhaust. It is required that the exhaust goes
vertically for a minimum of 2 feet above the unit before a 90 degree elbow is installed and after the
venting exits the home it must be terminated above the eave of the house. This will help draw smoke out
of the stove in the event of a power failure.
FREESTANDING STOVE INSTALLATION REQUIREMENTS
(Limited) Horizontal Exhaust Termination:
1) Position stove on the noncombustible floor pad with the proper clearances to combustibles and in
the location that you have determined will work. Place a Pipe Adaptor over the 3” starter pipe
located on the top back of the stove and clamp into place using a 3” hose clamp. Note: It is not
recommended to use silicone on this connection as it will have to be removed for cleaning and
maintenance.
2) It is required that a minimum of 24” of vertical venting is installed before going horizontally.
Horizontal venting cannot exceed 36” in length. Locate proper position for the type “PL” wall

3) NOTE: Make sure that you leave enough clearance between the wall and the back of the unit so
that you will be able to install the outside air and work on the intake fan.
4) NOTE: In cold climates running the venting on the outside of the home without an insulated chase
way will cause condensing, creosote buildup, staining of siding and poor operation of the unit. It is
strongly recommended that all venting is run on the interior of the home and if that is not possible,
install venting in an insulated chase way.
5) INSTALL VENTING AT CLEARANCES SPECIFIED BY THE VENTING
MANUFACTURER. American Energy Systems does not assume responsibility for the venting
design or installation of the product. Diagrams are shown as a reference and a guide for clearances.

CLEANING THE GLASS
When the fire is first started, it will produce some smoke. The smoke might accumulate on the glass
surface. Before the fire gets hot, open the door and wipe the glass surface off with a damp rag. Do not
touch the surface with your hands. If after constant use, the glass is dirty; you must clean the glass so that
it will not become etched with the fly ash. When the glass has cooled off, take a damp rag, put a little fly
ash from the unit on it and clean the glass. If this does not clean the glass use a special glass cleaner
provided by your Avent Wood Pellet reseller. We have found that Amway crème glass & chrome
cleaner works real well.

12 volt DC wiring installation
The Avent pellet stove is designed to operate on a
12 volt DC battery system for extended back-up
periods. This system may also be used in
conjunction with 12 volt solar systems.
WARNING: THE STRUCTURAL
INTEGRITY OF THE HOME MUST BE
MAINTAINED IF INSTALLING THIS
SYSTEM.
Disconnect 110 power source before connection of
12 volt dc battery. Determine proper length of 18
gage stranded wire to run from battery to unit.
Install ½” conduit if passing through a wall or floor.
Connect Red 18 gauge stranded wire to red (+)terminal
and Black 18 gauge stranded wire to black (-) terminal
on back of stove. Pass wires through conduit leaving
room for a drip loop between connections so that
moisture will not get on connections. Install a 4 amp
inline fuse on the red (+) lead near the battery. Connect
the red (+) lead to the positive terminal and the black (-)
lead to the negative terminal on the battery. Reconnect
the 110 power source and the unit is ready to operate.
The system will switch between 12 volt and 110 volt and
charge the battery automatically.

NOTE: This appliance is designed to burn premium wood pellets, olive pits or cherry pits. Do not burn corn
or any other fuel. Do not overfire this appliance. Do not bypass any safety or operational switches. Over
firing this appliance will cause damage to the heat exchangers, and cause the safety switches to shut the
appliance down. Over firing can be caused by excessive positive pressure in the home. This must be
corrected.
Priming the Auger System: Never leave the appliance unattended while priming the auger system
or during startup of the unit. Priming the auger will be necessary if the hopper has run out of fuel
or you are starting the unit for the first time.
Procedure: Load the hopper with wood pellets, Set the power switch to the “on” position. Note: This is
the low fan/burn speed when the appliance is operating.
Press the “start/manual feed” button and hold the button down for approximately 2-3 minutes or until
pellets begin to feed. The auger light will come on, indicating that the auger motor is running. Note:
When the pellets begin to drop regularly, the auger is primed. Allow the pellets to accumulate in
the firepot until one even layer of fuel is in the firepot. The start button may now be released.
Set the power switch to the “off” position.
Starting the Avent Pellet Stove: Note: Each time the appliance is started, the firepot should be
checked for debris and clear the air holes. Do not allow ash to build up underneath the firepot.
If there are not any pellets in the firepot from priming, add app. ½” of fuel to the firepot.
Open the door and add a small amount of fire starter gel (Evenly across the wood pellets)on top of the wood
pellets. (app. ½” of fuel) Light the fire starter and wait app. 1-minute for it to start burning. Close the door.
9Pull out the manual draft knob approximately ¼ inch. (more or less if necessary)
9Once the wood pellets are burning good set the power switch to the “on” position and adjust the manual draft
knob (located on the right side of the unit so that there is approximately ½ inch of fuel in the bottom of the
firepot. This level cannot be determined quickly. Minor adjustments will have to be made until the main fuel
starts coming in and the unit is up to temperature. The heat selector switch should be on the med. Setting.
9Let the fire continue to build for approximately 1-2 minutes, then press the “start/manual feed button
momentarily and release. Note: The green power light will come on, indicating that the auger timer is
energized. If the firepot begins to fill up with unburned fuel, open the manual draft knob a little to burn up the
excess fuel. If the fire is going out because there is too much fuel coming in, adjust the manual air damper in a
little until the fire load is balanced. Small adjustments to the air setting will give the best results.
9Once the fire has established itself (usually 10 to 15 minutes) select the low, med or high setting and adjust the
manual draft knob so that there is approximately ½ inch of fuel in the bottom of the firepot. Do not let the fuel
build up any higher than that or it will cause the fire to burn dirty and you will get excessive ash. If the
fuel level is too low (below ¼”) the fire may go out.
9The air damper setting will vary with fuel, venting and weather conditions. Adjustments will need to be
made periodically to maintain a balanced fire.
PRIMING / LIGHTING / OPERATING INSTRUCTIONS
Before lighting your Avent Wood Pellet Stove for the first time make sure that all items are out of the hopper
and firebox area. Turn the heat setting to the off position and push the manual draft in as far as it will go.
Note: If using a wall thermostat option make sure that the thermostat is turned up above room temperature.
The unit will o
p
erate on low fire if
