    SECTION I The New Buck Corporation room heater Model 20 is one of the safest and most efficient heating systems available when installed and operated as specified in these instructions and as stipulated on the operation and installation labels affixed to the unit. The unit is designed to burn wood fuel only.

  • Page 5: Important Statements

    EPA COMPLIANCE STATUS This manual describes the installation and operation of the New Buck Corporation, Model 20 wood heater. This heater meets the U.S. Environmental Protection Agency’s Emission limits for wood heaters sold after July 1, 1992. Under specific test conditions this heater has been shown to deliver heat at rates ranging from approximately 10,000 to 39,000 BTU/hr.

  • Page 6: Catalyst Monitoring

    CATALYST MONITORING It is important to periodically monitor operation of catalytic combustor to ensure that it is functioning properly and to determine when it needs to be replaced. A non-functioning combustor will result in a loss of heating efficiency and an increase in creosote and emissions. The following is a list of items that should be checked on a periodic basis.

  • Page 30: Safety

    SECTION VI WOOD HEATER SAFETY Certain safety hazards are inherent in any wood heater installation. You should be aware of these so that a safe and proper installation can be made. FAULTY CHIMNEY: An older masonry chimney should be thoroughly checked to be sure there are no holes or weak spots which could allow sparks or hot gases to escape.

  • Page 31: Operation

    NOTE: Do not use grate or elevate fire. Build wood fire directly on inner bottom of fire box. 5. The Model 20 is not designed for use of grates and irons or other methods of supporting fuel. 6. Lay several pieces of dry kindling on top of newspaper.
  • Page 32 C. Medium—High Burn Rate: Set the primary air control wide open. Set the Auto-Off-Manual switch to Auto position. Wood Loading—During refueling, open bypass damper, open door and add wood. Immediately close door and bypass damper. Open primary air control wide open for five minutes to charge wood.

  • Page 33: Operating And Safety Hints

    OPERATING AND SAFETY HINTS: When preparing to refuel heater, open bypass damper (taking the heater out of catalytic mode) and wait for smoke to clear out of firebox before opening the door. Burn only natural seasoned hard wood in your catalytic heater. You should not burn trash or garbage, artificial or paper logs, gift wrapping, treated or painted wood, nor should you start a fire with lighter fluid or chemical starter.

  • Page 34: Manufacturers Suggested Preventive Maintenance

    SECTION VIII PREVENTIVE MAINTENANCE / PARTS REPLACEMENT Check Chimney A. The chimney should be cleaned as necessary to remove creosote, soot, leaves, birds nests, etc. (Refer to Page 27, #5 Creosote Formation.) B. A neglected chimney can eventually cause a draw restriction or can ignite and burn hot enough to cause damage to chimney.

  • Page 35: Catalyst Replacement

    Properly functioning catalysts will be exhibiting a uniform glow from one end to other (indicating ignition). Physically degraded catalysts will have cold places (areas not igniting) where plugging, crumbling or other degradation has occurred. If this occurs, monitor probe temperature will not increase at a normal rate.

    Using penetrating oil, generously lubricate four (4) bolt threads holding catalyst housing in place. Allow to penetrate. Using a 9/16” wrench or 9/16” socket, loosen four (4) bolts and remove catalyst housing (drop down) and place in a suitable work area. Using needle nose pliers, grasp front edge of stainless steel “can”...

  • Page 39 DEFINITIONS AIRTIGHT HEATER—In an airtight heater, all air enters in through inlets. Generally, non-airtight stoves are not as efficient and their level of heat output is less controllable than that of an airtight. BURN CYCLE—Time span between refueling in which wood is reduced to a bed of hot coals. BYPASS—Movable door inside a woodstove that is opened when stove door is opened to give a path of least resistance to smoke to prevent roll-out.
  • Page 40 POSSIBLE PROBLEMS Problems encountered with operation of catalytic-combustor equipped wood heaters are usually the same as those experienced in operation of traditional wood heaters. Our experience has shown that adoption of good operating practices will eliminate most of these problems. In addition, it should be noted that problems with catalytic combustors are rare.

  • Page 41: Troubleshooting

    Backpuffing-A hot combustor (above 1400 F) can sometimes act like a glow plug (spontaneous combustion igniter). Usually wood gas-to-air mixture is either too lean or too rich to form a highly flammable mixture. There are times when this mixture is just right within firebox during normal burning process. If combustor is running at or above ignition temperature of mixture, spontaneous combustion will result, causing stove to vent puffs of smoke.
