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. Please read this entire manual before you install and use your new room heater. Failure to follow instructions may result in property damage, bodily injury, or even death.
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.
CATALYST MONITORING It is important to periodically monitor the operation of the 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. Following is a list of items that should be checked on a periodic basis.
SECTION II MASONRY INSERT INSTALLATION INSTALLATION PRECAUTIONS Extensive field and laboratory testing has shown that catalytic stoves perform best as fireplace inserts when: 1. A direct connect kit is used to connect the stove exhaust outlet directly to the masonry flue of the fireplace when flue liner size is approximately the same size as the heater flue gas exit. A rain cap is also recommended to keep flue dry thus allowing a hotter draft.
MINIMUM CLEARANCES: The Model 20 Fireplace Insert is intended for installation in accordance with the standard for chimneys, fireplaces, vents, and solid-fuel burning appliances, NFPA-211 Code. This model is not intended for installation into factorybuilt metal fireplaces or for use with a metal chimney (except as listed in Section V of this manual). 1.

Set switch to “Manual” position to ensure motor operates properly. 5. Place crumpled pieces of newspaper in the stove. Light it and close the door. Ensure that the stove draws properly through the primary drafts. 6. Check for smoke leaks around the door. 7.
SECTION III RESIDENTIAL FREESTANDING ROOM HEATER INSTALLATION INSTALLATION PRECAUTION Extensive field and laboratory testing has shown that catalytic stoves perform best as freestanding stoves when vented into a masonry chimney if: 1. 2. 3. A rain cap is installed on the chimney. Height of chimney is at least 15 feet high. Location of chimney is interior (not on an outside wall). NOTE: Certain types of double wall pipe (close clearance) also cause a substantial drop in flue gas temperature.
MINIMUM CLEARANCES The New Buck Corporation Model 20 must be installed in compliance with the instructions contained in this manual. CLEARANCE FROM COMBUSTIBLE WALLS AND CEILINGS (Using single wall chimney connector) The minimum lateral distance between any part of the room heater and combustible walls is shown in Figures 1 and 2.

This third method of installation is to use the masonry fireplace trim kit to seal the stove to the Pre-Fab fireplace. CAUTION! Although this method is a tested and approved method, some codes may not allow this type installation so be sure to check local codes for approval prior to making this type of installation.
2. To complete this installation, follow the basic masonry fireplace trim kit installation instructions except: The trim kit may have to be cut down in size so as not to block any cooling vents/chambers of the PreFab Fireplace. 3. To complete methods 1 and 2: Position the heater into the Pre-Fab Fireplace and center the flue exit under the connector. 4. Slide the connector (or slip connector) down into the flue exit of the heater approximately 3/8”.
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. 1. 2. 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. HEAT CONDUCTION: Placing combustible materials too close to a heater or chimney can be a fire hazard.
SECTION VII OPERATION This section of the manual is to help you get the maximum efficiency and maximum smoke (particulate) reduction from your heater. If you should experience any difficulty or have any questions concerning your heater, contact your dealer for assistance. Build a fire for maximum efficiency. This model burns wood and extracts heat so efficiently, a large fire is not necessary. A large fire not only wastes energy, it usually results in the home being too warm for comfort.
and door to rake the wood and coals into a pile near the front center of the firebox. (Be certain wood chunks are pulled out of the rear corners.) Close door and bypass damper. This step will assure continued combustion and thorough burning of the wood. D. High-Burn Rate—Set primary air control wide open. . Set the Auto-Off-Manual switch to the Auto position. Wood Loading—During refueling, open the bypass damper, open the door, and add wood. Immediately close door and bypass damper.
OPERATING AND SAFETY HINTS: When preparing to refuel the heater, open the bypass damper (taking the heater out of catalytic mode) and wait for the smoke to clear out of the firebox before opening the door. Burn only natural 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.
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 the chimney. C. For proper inspection the chimney should be cleaned. D.
a. b. Properly functioning catalysts will be exhibiting a uniform glow from one end to the other (indicating ignition). Physically degraded catalysts will have cold places (areas not igniting) where plugging, crumbling, or other degradation has occurred. If this occurs, the monitor probe temperature will not increase at a normal rate.
4. Using penetrating oil, generously lubricate the four (4) bolt threads holding the catalyst housing in place. Allow to penetrate. 5. Using a 9/16” wrench or 9/16” socket, loosen the four (4) bolts and remove the catalyst housing (drop down) and place in a suitable work area. 6. Using needle nose pliers, grasp the front edge of the stainless steel “can” which houses a catalytic element and pull upward. 7.
OPERATION OF SWITCH With Power Cord Plugged Into 115V AC Outlet. (A) For Auto position push in top of switch. When the room heater becomes warm enough the Room Air Blower will come on and stay on until your room heater falls below the activating temperature for the thermostat. (B) For Off position place the switch in the middle position. (C) For Manual position push in on the bottom of the switch. This will allow your Room Air Blower to operate without the thermostat being activated.
SECTION IX CATALYTIC TROUBLESHOOTING CONTENTS Definitions Possible Problems Plugging Extreme Temperatures Flow Restrictions Creosote Build-up Chemical Deactivation Excessive Handling Condensation in Chimney Backpuffing Non-uniform flow Troubleshooting Heater Related Problems 1. Sluggish Heater Performance 2. Drop in Overall Efficiency 3. High Fuel Consumption 4. Backpuffing 5. Smoke Rollout When Heater Door Is Opened 6. Low Catalytic Temperature 7.
DEFINITIONS AIRTIGHT HEATER—In an airtight heater, all air enters in through the 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 refuelings in which the wood is reduced to a bed of hot coals. BYPASS—Movable door inside a woodstove that is opened when the stove door is opened to give a path of least resistance to smoke to prevent roll-out. CREOSOTE—Condensed wood-gas vapor.
POSSIBLE PROBLEMS Problems encountered with the operation of catalytic-combustor equipped wood heaters are usually the same as those experienced in the 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-fewer than 1 percent of combustors are returned for any reason.
Backpuffing-A hot combustor (above 1400o F) can sometimes act like a glow plug (spontaneous combustion ignitor). Usually the 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 the firebox during the normal burning process. If the combustor is running at or above the ignition temperature of the mixture, spontaneous combustion will result, causing the stove to vent puffs of smoke.

If the unit is located in a moist or damp location, check thoroughly for signs of condensation during times when the unit is not in use. C. When the heating season is over, the unit can be cleaned out completely with a wire brush or cloth to help eliminate ash and burned wood smell. SAFETY PRECAUTIONS 1.
PREVENTIVE MAINTENANCE/ SAFETY PRECAUTIONS CHIMNEY A. The chimney should be cleaned as necessary to remove creosote, soot, leaves, birds’ nests, etc. CREOSOTE-FORMATION AND NEED FOR REMOVAL When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining.
