Installation and Operating Manual Model AWC11 Coal Only Stove • ASSEMBLY • INSTALLATION • OPERATION REPAIR • PARTS Conforms To: UL 1482 SAFETY NOTICE: If this heater is not properly installed, a house fire may result. To reduce the risk of fire, follow the installation instructions.
Rules For Safe Installation And Operation SAVE THESE INSTRUCTIONS! READ THESE RULES AND THE INSTRUCTIONS CAREFULLY. 1. Check local codes. The installation must comply with their rulings. Do not install this heater in a mobile home or trailer. 2. Always connect this heater to a chimney or vent to the outside. Never vent to another room or inside a building.
LOCATING THE HEATER AS A LOCATION IS SELECTED, KEEP THE FOLLOWING MIND 1. The chimney connection should be as airtight as possible. The heater must have its own chimney flue. Do not connect this unit to a chimney flue serving another appliance. If there is no chimney near where you wish to place the heater, you can use a UL 103HT Residential Type and Building Heating Appliance Chimney.

CHIMNEY CONNECTION Two basic types of chimneys are approved for use with solid fuel: Factory-built and masonry. Factory-built chimney must comply with UL 103 type “HT” standard. Do not expect your stove or furnace to create draft. Draft is not a function of the appliance. It is purely a function of the chimney.

Chimney Your stove may be hooked up with a 6” factory built or masonry chimney. If you are using a factory built chimney, it must comply with UL 103 standard; therefore it must be a Type HT (2100°F). It is extremely important that it be installed according to the manufacturer’s specifications.
Factory Built Chimney When a metal prefabricated chimney is used, the manufacturer’s installation instructions must be followed. You must also purchase (from the same manufacturer) and install the ceiling support package or wall pass-through and “T” section package, firestops (where needed), insulation shield, roof flashing, chimney cap, etc. Maintain proper clearance to the structure as recommended by the manufacturer.

Venting Into A Fireplace Many people may wish to convert an existing fireplace to heater use. Usually, safe connection of stovepipe to a masonry chimney requires more effort than connection to a prefabricated chimney. The fireplace must be closed and sealed at the damper in the flue. Good sealants are high temperature caulking, ceramic wool, and furnace cement.
Masonry Chimney Masonry Chimneys have several positive attributes: If properly built, they are quite durable, and most homeowners consider them more attractive perhaps than a non-enclosed factory built chimney. And, if the chimney is located within the confines of the house (that is, not attached to an exterior wall), its mass alone will store heat longer and continue to release the heat long after the fire has died.

Masonry Chimney Ensure that a masonry chimney meets the minimum standards of the National Fire Protection Association (NFPA) by having it inspected by a professional. Make sure there are no cracks, loose mortar or other signs of deterioration and blockage. Have the chimney cleaned before the stove is installed and operated. When connecting the stove through a combustible wall to a masonry chimney, special methods are needed.
COMBUSTIBLE WALL CHIMNEY CONNECTOR PASS-THROUGHS Method A. 12” (304.8 mm) Clearance to Combustible Wall Member: Using a minimum thickness 3.5” (89 mm) brick and a 5/8” (15.9 mm) minimum wall thickness clay liner, construct a wall pass-through. The clay liner must conform to ASTM C315 (Standard Specification for Clay Fire Linings) or its equivalent.
Operating Instructions FUEL RECOMMENDATIONS COAL Most sizes of bituminous coal will work in your heater; for best results we recommend large nut coal to small egg coal (1-3/4” diameter to 4” diameter). When burning anthracite, use egg or broken with sizes between 2-5/16” and 4-3/8”.
Bulletine RC454 A GUIDE TO BURNING COAL IN YOUR HEATER Heaters that are capable of burning coal usually will burn both Bituminous and Anthracite coal. Anthracite is perhaps the best coal fuel because of its long even burn time, high heat output, and cleanliness which make it a good choice for the home.

ANTHRACITE Add a thin layer of coal (preferably smaller chunks) to the wood fire, being careful not to disturb it too much or cut off the draft. Then, add a second heavier layer after the coal is ignited and burning well. If necessary, add a third layer to bring the coal up to the top of the front liner (not above!).
Maintenance DISPOSAL OF ASHES Ashes should be removed from the stove every few days or when ashes get to 2 to 3 inches deep. Always empty the stove when it is cold, such as in the morning. Ashes should be placed in a metal container with a tight fitting lid.
