FIGURE 5 - FLOOR PROTECTION FLOOR PROTECTION This heater has been designed to prevent excessive temperatures on the floor beneath the heater. It is important, however, that a combustible floor be protected by a 3/8 inch minimum thick noncombustible inorganic millboard having a 2 thermal conductivity of K=0.43 BTU/ft. /in./hr./°F or a listed floor protector beneath the heater extending beyond the heater as shown by figure 5. The floor covering is required to prevent damage or possible ignition

There are five allowable ways that a chimney connector can be connected to a masonry chimney by passing through a combustible wall. NFPA Standard 211 allows the following wall pass-through systems. 1. Use a minimum 3-1/2" thick brick masonry wall framed into the combustible wall. A fireclay liner (ASTM C315 or equivalent) having a 5/8" minimum wall thickness must be used and it must be at least 12" away from any material that could catch fire. The inside diameter of the fireclay liner shall b

AIR SPACE There are basically two methods of metal prefabricated chimney installation. One method is to install the chimney inside the residence through the ceiling and the roof. The other method is to install an exterior chimney that runs up the outside of the residence. REMEMBER: Follow the chimney manufacturer's installation instructions and maintain the manufacturer's specified clear- ance distance. Additional chimney information is presented throughout this manual. READ IT THOROUGHLY TO

FIGURE 8 - CONNECTING HEATER’S CHIMNEY CONNECTOR TO MASONRY CHIMNEY WHEN CHIMNEY CON- NECTOR DOES NOT HAVE TO PASS THROUGH A COMBUSTIBLE WALL HEATER INSPECTION Before installing the heater, inspect the heater for external damage and missing parts. Check the gaskets around the doors to assure that they are still in place. Also check inside the heater. Report any deficiencies found to your heater dealer and make sure all problems are resolved before installing the heater. See figure 12 for il

Two common types of clearance reductions systems use sheet metal with a thickness of 28 gauge (galvanized steel, aluminum, copper) or a 3-1/2 inch (4 inch thick nominal) thick masonry wall. Either of these materials must be spaced out 1 inch from the combustible surfaces. With sheet metal, noncombustible spacers are used to maintain the 1 inch air space. With a masonry wall, metal wall ties and furring strips, if needed, are used to anchor the brick to the wall. To avoid excessive heat trans

HEATER OPERATION IMPORTANT: DO NOT USE THE HEATER UNTIL A PROFESSIONAL INSPECTION HAS BEEN MADE OF THE ENTIRE INSTALLATION BY YOUR LOCAL FIRE DEPARTMENT, FIRE MARSHAL OR BUILDING CODE INSPEC- TOR. INSTALL A SMOKE DETECTOR ON EACH FLOOR OF YOUR HOME; IN CASE OF ACCIDENTAL FIRE FROM ANY CAUSE IT CAN PROVIDE TIME FOR ESCAPE. This heater must be operated as outlined in this manual or a serious fire may occur. THE PAINT ON THE EXTERIOR OF THE FIREBOX WILL GO THROUGH A CURING PROCESS DURING THE FIRS

FIGURE 10 - OPENING AND CLOSING FUEL FEED DOOR FIRETENDING Firetending is the occasional poking or stirring of the burning fuel bed to ensure airflow through the fire and adding new wood as needed. With experience, you should determine how often fire tending is required to maintain the desired heat output of the heater. To ensure safe and satisfactory performance of the heater, the following rules should be observed. 1. KEEP THE FEED DOOR AND ASH DOORS CLOSED EXCEPT WHEN TENDING THE FIRE OR R

The second factor in determining heat output is its density or weight per cord. With equal seasoning and dryness, heavier, denser wood has more heating value per cord. For example, hickory is denser wood than pine, so a cord of hickory will give more heat than a cord of pine. For longer and safer heater life, never use manufactured composition logs, salt water soaked wood (driftwood), or chemical additives in this heater.

Tap each chimney connector pipe with a small hammer or poke with a screwdriver to reveal where the metal is getting thin due to corrosion on the inside. Elbows usually give out first. Replace as necessary. YOU SHOULD ALWAYS INSPECT AND CLEAN THE HEATER’S VENTING SYSTEM BEFORE EACH HEATING SEASON. TROUBLESHOOTING Problems can arise during the operation of any wood heater. These problems can usually be traced to such things as the venting system, draft, aged or failed parts, fuel, and operator

6. Check the entire system for obstructions that could be causing resistance to the flow of smoke and gases up the chimney. 7. Check the size of the chimney flue liner. If the chimney flue liner’s inside dimension is smaller that 6 inches round or 8 inches square, it will be too restrictive to the flow of smoke and gases. A chimney flue liner which has an inside cross-sectional area of more that 85 square inches is too large, which will result in excess capacity, which means

2. Symptom: Fire rate too high when thermostat closed: Check for: a. Feed door or ash door not securely closed. b. Feed door or ash door gasket worn excessively. 3. Symptom: Smoke smell in living space: Check for: a. Items a through f of NO. 1 above. FINAL CHECKLIST OF DO’S AND DON’TS DO’S 1. Do read and follow the installation, operation and maintenance manual carefully. 2. Do install a smoke detector in an area that will give warning in the unlikely event that a

DONT’S 1. Don’t dry clothing or other articles on or near the heater. 2. Don’t store or place flammable liquids, gases, or other pressurized containers near the heater. 3. Don’t use gasoline, gasoline type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or intensify a fire. Using these and other similar materials can cause an explosion within the heater. 4. Don’t use an unlisted, type B, or poorly constructed or maintained chimney to vent this heater. 5. Don’t use ga
