CLEAN BURN
CORN ADDITIVE TM
AMERICAN ENERGY SYSTEMS INC. HAS DEVELOPED AN ADDITIVE THAT WHEN MIXED WITH CORN VIRTUALLY ELIMINATES THE (CLINKERING) THAT IS CAUSED BY THE COMBUSTION PROCESS OF BURNING CORN.
HOW DOES IT WORK AND WHY DO YOU NEED IT?
The clean burn additive is a unique blend of the right ingredients that will oxygenate the combustion process producing a cleaner more productive fire. This will generate more BTU’S out of corn, clean up the combustion process and produce less ash.
HOW DO YOU MIX THE CLEAN BURN ADDITIVE?
Depending on how much starch or protein content that you have in your corn supply you will have to change the percentage of mixture. The normal mixture is a ratio of one (1) part Clean Burn additive to 150 parts of corn. This translates to approximately 1/2 pound of Clean Burn for every hopper of corn. (app. 1-2 handful’s)
To mix the Clean Burn additive simply add it to the corn and mix in by hand.
If you have corn with low starch content you may be able to decrease the mixture, and corn with high starch content will require more. The easiest way to tell if the mixture is right is, after a day of burning, look at the Fuel Stirrer in the Firepot and if there is any buildup of clinker on the fingers you need to increase the mixture.
If there is excessive white powder in the firepot you can decrease the mixture.
Using the Clean Burn additive will reduce maintenance, ash content, buildup in the firepot, fly-ash on the outside of the home and will increase the heat output. The additional heat output will more than pay for the cost of the additive.
CAN I STILL USE OYSTER SHELLS AS AN ADDITIVE?
We have found that the oyster shells, even though they will work, causes auger jams, pre-mature wear or damage to the auger motor and excessive ash buildup. We do not recommend that you continue to use oyster shells and if you do use them it will void warranty on the auger system.
GIVE CLEAN BURN A TRY. YOU WILL BE PLEASANTLY SURPRISED.

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 the factory for suggestions. 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 test weight of Corn varies 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 Countryside is certified to burn shelled corn and wood pellets. The Countryside will burn other fuels such as Cherry Pits, Barley, Oats, Wheat and other identified fuels but the feed rates and safe operation are not warranted. 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.

BURNING SOLID FUELS (shelled corn and wood pellets)
Unlike petroleum and natural gas products, solid fuels such as corn and wood pellets create ash as the fuel is burned. Even with the highly efficient flame your Countryside 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 Countryside 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 are an important part of burning solid fuels.
The Countryside stove has been designed to burn shelled corn or wood pellets that meet the Association of Pellet Fuel Industries standards. Since both of 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 container sealed to prevent your corn from absorbing excess moisture. Test the moisture content periodically to maintain the proper dryness.
Check 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.
If you are having trouble finding clean Corn, contact your local Countryside Reseller 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.
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
9As with corn, be consistent in your pellet supplier. Pellets will vary in content and burn characteristics from supplier to supplier. A consistent supply of pellets will require fewer adjustments to the draft of the stove.
9Check your 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 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 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 Countryside reseller for more information on approved wood pellet fuel.
UNPACKING YOUR COUNTRYSIDE CORN/PELLET STOVE
When you receive your Countryside Corn/Pellet Stove, 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 Countryside 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 Countryside reseller or contact the factory right away. Your satisfaction is our top priority.
To uncrate your Countryside Corn/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.
8
The Pedestal Ash Pan 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. Unpackage the legs and get the (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 (4) four nuts. Make sure not to over tighten the nuts and twist them off.
FLOOR PROTECTION
The Countryside 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 in front of and (8) eight inches from each side of the ash removal door.
NOTE: If installing the 3502 (Insert Model) into a build-in application where there is not an existing fireplace, you will have to install a non-combustible floor underneath and 6 inches out in front of the unit. This would require a 2-3 inch thick masonry floor (the thickness of one brick) or ¾ inch thick rock board.
9
CLEARANCES TO COMBUSTIBLES
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.
When venting straight out the back of the unit, the B clearance is 1”. C clearance is for a vertical vent install.

GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN
It is recommended that only an authorized Countryside installer install your pellet/corn 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 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.
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 900 junction to enable collection of fly ash and to permit periodic cleaning of the exhaust system. 900 elbows accumulate flyash and soot thereby reducing exhaust flow and performance of the stove.
9Total length of horizontal vent must not exceed 48” (4 ft.) / 1,200 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.
9A 3” 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 450 to enable the vent to be centered on the stove and allow the “tee” to be cleaned without removing the stove (see diagram on page 17).
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.
9If an insert is to be installed into an unlined masonry chimney, it is recommended that at 3” or 4” 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 on page 17).
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 30 feet.
