9 3-90-04301c Fuel and Fuel Storage Pellet fuel quality can fluctuate from manufacturer to manufacturer, and even from bag to bag. Hearth & Home Technologies recommends using only fuel that is certified by the Pellet Fuels Institute (PFI). Fuel Material • Made from sawdust and/or other wood by-products • Shelled field corn (when mixed with wood pellets) • Source material typically determines ash content Higher Ash Content Material • Hardwoods with high mineral content • Bark and leaves as source material • “Standard” grade pellets, corn and other biomass Lower Ash Content Material • Softwood; pine, fir, etc. • Materials with lower mineral content • “Premium” grade pellets Shelled field corn • Must be 15% moisture content or less • Must be clean and free of debris • Must be mixed with wood pellets. (Up to 50%) • Stalk parts, excessive fines and cob remnants may cause feed system jams or blockage CAUTION! Do not burn fuel that contains an additive; (such as soybean oil) • May cause hopper fire • Damage to product may result Read the list of ingredients on the packaging. If you are buying field corn, the only ingredient listed should be field corn. WARNING! Risk of Chemical Poisoning! Do NOT burn treated seed corn • Chemical pesticides are harmful or fatal if swallowed • Burning treated seed corn will void the product warranty Clinkers Minerals and other non-combustible materials, like sand, will turn into a hard glass-like substance when heated. Trees from different areas will vary in mineral content. For this reason, some fuels will produce more clinkers than others. Moisture Always burn dry fuel. Burning fuel with high moisture content takes energy to dry and tends to cool the appliance thus, robbing heat from your home. Damp pellet fuel could turn back into sawdust which does not flow properly through the feed system. NOTICE Hearth & Home Technologies is not responsible for stove performance or extra maintenance required as a result of using fuel with higher ash or mineral content. Size • Pellets are either 1/4 inch or 5/16 inch (6-8mm) in diameter • Length should be no more than 1-1/2 inches (38mm) • Pellet length can vary from lot to lot from the same manufacturer. Performance • Higher ash content requires more frequent maintenance. • “Premium” grade pellets will produce the highest heat output. • Burning pellets longer than 1-1/2 inches (38mm) can cause inconsistent feeding and/or ignition. We recommend that you buy fuel in multi-ton lots whenever possible. However, we do recommend trying different brands prior to purchasing multi-ton lots, to ensure your satisfaction. CAUTION! Tested and approved for use with wood pellets and a mixture of shelled field corn and wood pellets ONLY. Burning of any other fuel will void your warranty. When changing from wood pellets to a corn/pellet mixture, the Feed limit will likely need adjusted to a lower setting. When under maximum demand, ensure there is no unburned fuel being pushed into the ash pan. Storage • Wood pellets should be left in their original sealed bag until ready to use, to prevent moisture. • Shelled corn should be stored in a tightly sealed container to prevent moisture and to deter pests • Do not store fuel within the specified clearance areas, or in a location that will interfere with routine cleaning and maintenance procedures. D. Fuel Specifications CAUTION ! Tested and approved for use with wood pellets and a mixture of shelled field corn and wood pellets ONLY. Burning of any other fuel will void your warranty.

10 3-90-04301c E. Before Your First Fire 1. Make sure your appliance has been properly installed and that all safety requirements have been met. Pay particular attention to the fire protection and venting instructions. 2. Double check that the ash pan and firebox are empty! 3. Close the front door. Fire Hazard. Keep combustible materials, gasoline and other flammable vapors and liquids clear of appliance. E. General Operating Information 1. Room Sensor Calls For Heat The appliance is like most modern furnaces; when the room sensor calls for heat, your appliance will automatically light and deliver heat. When the room is up to temperature and the room sensor is satisfied, the appliance will shut down. 2. Heat Output Controls The appliance will turn on and off as the room sensor demands. When the room sensor calls for heat, the appliance will always start up on High. After burning approximately 7-10 minutes, the appliance will then burn at the rate at which it was originally set. If the appliance is set at one of the lower settings, it will run quieter but take longer to heat up an area than if it were set at a higher burn rate. Regardless of the burn rate, when the area is warm enough to satisfy the room sensor, the appliance will shut off. WARNING ! • Do NOT store flammable materials in the appliance’s vicinity. • NEVER use gasoline, GASOLINE-TYPE lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this heater. Keep all such liquids well away from the heater while it is in use. • DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS SUCH AS GASOLINE, NAPHTHA OR ENGINE OIL. • DO NOT USE CHEMICALS OF FLUIDS TO START THE FIRE. • Combustible materials may ignite. Figure 3.1

11 3-90-04301c B. Fire Characteristics A properly adjusted fire has a medium active flame pattern that extends out of the burn pot approximately 6 inches (152mm). C. Feed Rate Adjustment Instructions The feed adjustment control is factory set at #4, and should be adequate for most fuels. However, if the flame height is too high or too low, you will need to adjust the feed rate. Wait until the appliance has been burning for 15 minutes before making your adjustments and allow 15 minutes for feed adjustment to take effect. A. Starting Your First Fire 1. A room sensor is required for proper operation of this appliance in “Room Temp” mode. At this time, fill the hopper with pellets, insure the control is set to “OFF”. Figure 4.2. Plug the power cord into a properly grounded, nearby outlet. 2. Once power is present, the unit it will run through a quick diagnostics test to insure the control is operating properly. This is normal. 3. For your first fire it may be necessary to purge the auger system by putting the feed limit knob to “Test” prior to starting the unit. Figure 4.3. This insures that plenty of fuel enters the burn pot for proper ignition. 4. Flip toggle switch to desired mode “auto or manual”. Figure 4.4. Set feed limit knob to desired setting and turn mode dial to “Room Temp” or “Constant burn” Figure 4.5. Note: Feed rate of #4 is a good starting point. Adjustments may need to be made depending on fuel quality and/or heat output desired. 5. The fuel feed system and the igniter should now be on. 6. Once the appliance has ignited, let it burn for approximately 7-10 minutes. After this time, the igniter light should turn off and the unit should begin to operate per the settings at the control. Figure 4.5 Odors and vapors released during initial operation. • Curing of high temperature paint. • Open windows for air circulation. Odors may be irritating to sensitive individuals. Figure 4.2 Figure 4.3 Figure 4.4 4 Operating Instructions CAUTION !

12 3-90-04301c D. Ignition Cycles 1. At the beginning of each ignition cycle, it is normal to see some smoke in the firebox. The smoke will stop once the fire starts. 2. The distribution blower will automatically turn on after your appliance has reached the set temperature. This blower transfers heat from your appliance into the room, and will continue to run in “constant burn” mode at the set speed you have the control knob at. In “room temp” mode however, the blower will turn on and off in accordance to what temperature the room sensor is reading. When the room sensor is satisfied the blower will shut down until the room sensor sees a demand for heat. 3. Occasionally the appliance may run out of fuel and shut itself down. When this happens, the unit will need to be turned to the off position and restarted. If needed, follow the instructions in Section A “Starting Your First Fire”. Fire Risk Do NOT operate appliance: • With appliance door open. • Burnpot floor open. • Cleaning slide plates open. Do NOT store fuel: • Closer than required clearances to combustibles to appliance • Within space required for loading or ash removal. WARNING !

13 3-90-04301c Igniter Switch to "AUTO" (up position) Make sure the unit is plugged into a properly grounded, 120 VAC, 60 Hz electrical source. The power light should be the only light lit. Note: Be sure there is no fuel or other combustibles in the ash pan prior to lighting. 1. Turn Mode Selector to "OFF". 2. Fill hopper with pellets. 3. Clean burn pot with scraper, if necessary. 4. If starting after an empty hopper, turn Feed Limit to "TEST" (for one 60 second cycle). This will flow pellets into the auger tube and also allow you to check the motors for operation. NOTE: The auger motor will not operate with the view door open. 5. Turn Feed Limit to #4. 6. Flip the Igniter Switch up into the "AUTO" position. 7. Turn the Temperature Dial to the desired room temperature. 8. Turn Mode Selector to Room Temperature or Constant burnerature. 9. Fill hopper with pellets and remove ashes as required. Keep the hopper lid and firebox doors closed while in operation. Maintain door seals in good condition. Failure to do so will affect operation of the appliance and may permit escape of smoke or gases into the living space. 1. Fines are small pieces of broken pellets (sawdust). Fines do not flow easily and often build up on the hopper funnel bottom angles. These fines can be pushed into the feeder opening and then fill the hopper with pellets. As the system works, they will be burned. 2. The "TEST" cycle will operate the feed motor for exactly one minute. Turning to "TEST" again and again may load too much fuel into the burn pot causing excessive smoke on start-up. 3. The firebox low pressure switch will not allow the auger motor or the igniter element to operate if the view door is open. 4. Adjust Feed Rate. If this is your first fire or you are trying different pellets, set the feed limit to #4, Figure 4.6 This is a conservative number and will probably need to be increased. After you know a feed rate setting that works well, use that setting. Remember, if your feed rate is too high you may waste fuel. 5. This is usually a weekly maintenance procedure. Cleaning the burn pot with the scraper with a small amount of new fuel in the bottom is not a problem. First, scrape the ashes off the front of the burn pot into the ash pan. Then scrape the holed surface downward into the burn pot. When the stove feeds, these scrapings will be pushed out by the feeder. 6. The ash pan can hold the ashes from approximately 1 ton of premium fuel. This means the ashes will only need to be emptied a few times a year. 7. Setting the feed limit # for maximum burn: With the unit burning in "AUTO", turn to "Stove Mode" and put the fan on "H". Set the Temperature Dial to #7. Allow the unit to burn for about 30 minutes and check ash on front of burn pot. Figure 4.7. If the ash line is larger than 1", turn the feed limit from #4 to #5. Allow another 30 minutes of burn time and check again. If, at #6 setting, a 1" or less ash bed is not obtainable, it is not a problem. The 1" ash bed is only at maximum burn rate and during normal operation, the ash bed will be larger. Figure 4.6 See Note 7 1" Figure 4.7 E. Automatic Ignition Burning garbage, use of improper fuels, fire starters or altering the stove For higher heat output may cause damage to the stove And could result in a House fire. Use only approved fuels And follow only these operation guidelines. WARNING ! NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR 'FRESHEN UP' A FIRE IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE HEATER, WHILE IN USE. WARNING !

14 3-90-04301c The P43 Pellet Stove is more than just automatic ignition, it is also automatic temperature control. The automatic system will allow the fire size to be adjusted to match the heating needs and even put the fire out if necessary. If heat is needed after the fire is out, the P43 Pellet Stove will automatically re-ignite and adjust the fire size to match the heating need. The totally automatic room sensor mode is recommended because of its efficiency. The unit can be switched between "AUTO" and "MANUAL" at any time during operation. Igniter switch to “AUTO” Room Temperature Mode In “Room Temp Mode” heat output is controlled automatically by the Room Sensing Probe. When the Room Sensing Probe calls for heat, the stove will increase output. When the Room Sensing Probe is getting close to the set temperature, the stove will begin to level off output and keep the fire burning at just the right temperature to maintain that setting. High output is determined by the feed rate setting. This setting, generally on #4, can be increased if higher burn rates are necessary (Figure 4.6). The unit’s maximum burn rate should not create less than 1” of ash on the burn pot front edge (Figure 4.7). Overfeeding is not a safety concern, but fuel may be wasted if unburned pellets fall into the ash pan. In “Room Temp Mode” a constant fuel consumption rate is sacrificed for exact room temperature. Therefore, as it gets colder more pellets will be burned automatically. The distribution blower speed will vary according to the position of the mode selector pointer, and fire size. Igniter switch to “AUTO” Constant burn Mode This allows for automatic ignition upon start-up only. The unit can then be set at any desired setting. The heat output and fuel consumption will remain constant regardless of room temperature. The unit’s maximum feed rate should not create less than 1” of ash on the burn pot front edge. Figure 4.7. The unit’s low burn or maintenance setting is as low as it will go. It will not go out unless it runs out of fuel or is turned off. Shut-Down Procedure To kill the fire or stop burning the stove, turn the Mode Selector to “OFF”. This will cause the fire to diminish and burn out. When the fire burns out and the stove cools down everything will stop. If you pull the plug to shut down the stove, all motors will stop. This may cause incomplete combustion and smoke in the firebox. If the load door is opened, the smoke may escape. The best way to shut down the stove is simply let it run out of pellets, then the stove will shut down automatically. Room Temperature Mode: This setting will produce a room temperature of 70 degrees with the distribution blower at medium speed. This setting will produce medium heat with the distribution blower on "low". This setting will produce continuous maximum heat output with the distribution blower at full speed. Constant burn Mode E. Automatic Ignition (Continued)

15 3-90-04301c See Note 7 1" Igniter Switch to “MANUAL” (down position) Make sure the unit is plugged into a 120 VAC, 60 Hz electrical source. The power light should be the only light lit. NOTE: Be sure there is no fuel or other combustibles in the ash pan prior to lighting. 1. Turn Feed limit to desired feed rate. No. 4 is good for most pellets. 2. Turn the Mode Selector to “OFF” and then to the desired mode. This will reset control and start the combustion motor. 3. Turn the Temperature Dial to the desired setting. 4. Clean burn pot with scraper if necessary. 5. Fill burn pot with pellets, only level with front edge. (Do Not Over Fill). 6. Add starting gel on top of the pellets. Stir gel into pellets for fast lighting. 7. Light starting gel with a match, and close the door. Operation will begin when the fire reaches the proper temperature. 8. Fill hopper with pellets and remove ashes as required. Store fuel in a dry area, away from all ignition sources and outside all limits of the stove's clearance requirements to combustibles. Do not store the fuel were it interferes with the refueling of the stove or emptying of ashes. Do not store any ashes removed from the stove near the fuel or other combustible materials. STARTER GEL 1. Fines are small pieces of broken pellets (sawdust). Fines do not flow easily and often build up on the hopper funnel bottom angles. These fines can be pushed into the feeder opening and then fill the hopper with pellets. As the system works, they will be burned. 2. The "TEST" cycle will operate the feeder motor for exactly one minute. Turning to "TEST" again and again may load too much fuel into the burn pot causing excessive smoke on start-up. 3. The low pressure switch will not allow the feed motor to operate if the viewing door is open. 4. Adjust Feed Rate. If this is your first fire or you are trying different pellets, set the feed limit to #4, Figure 4.8. This is a conservative number and will probably need to be increased. After you know a feed rate setting that works well, use that setting. Remember, if your feed rate is too high you may waste fuel. 5. Setting the feed limit # for maximum burn: With the unit burning in "AUTO", turn to "Stove Mode" and put the fan on "H". Set the Temperature Dial to #7. Allow the unit to burn for about 30 minutes and check ash on front of burn pot. Figure 4.9. If the ash line is larger than 1", turn the feed limit from #4 to #5. Allow another 30 minutes of burn time and check again. If , at #6 setting, a 1" or less ash bed is not obtainable, it is not a problem. The 1" ash bed is only at maximum burn rate and during normal operation, the ash bed will be larger. F. Manual Ignition Figure 4.8 Figure 4.9 Burning garbage, use of improper fuels, fire starters or altering the stove For higher heat output may cause damage to the stove And could result in a House fire. Use only approved fuels And follow only these operation guidelines. WARNING ! NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR 'FRESHEN UP' A FIRE IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE HEATER, WHILE IN USE. WARNING !

16 3-90-04301c F. Manual Ignition (Continued) The P43 Pellet Stove is capable of manual operation. This also allows the operator to manually control operation during an emergency (i.e. igniter failure, when using a 512H battery backup, or when using certain generators.) The unit can be switched between "AUTO" and "MANUAL" at any time during operation. Igniter Switch to "MANUAL" Room Temperature Mode The fire will have to be lit with starting gel and a match, or started automatically, see "Automatic Operation". Turn to "Manual" position once the start cycle begins. The difference between "AUTO" Room Temperature Mode and "Manual" Room Temperature Mode is that the fire will not go out as the room temperature goes above the control board setting. The unit can only go to low burn and will remain there until it runs out of fuel or until more heat is needed and the feed rate increases. Feed rate adjustments and dial settings are the same as "AUTO" settings. Igniter Switch to "MANUAL" Constant burn Mode The advantage of this mode is to allow the operator to have a large viewing fire without blowing extra heat into the room. During operation, with the temperature dial set at #4 or less, the distribution fan will not operate. A #4 on the temperature dial and a #4 on the feed limit is approximately 80% output. It is not necessary to operate the distribution blower below this point. Therefore, there can be a higher feed rate (a larger viewing fire) without an excess of hot air blowing into the room. An example of when to use the Manual Constant burn Mode is if you want to watch a large fire and the room is already up to temperature. The Constant burn Mode allows you to have a larger fire and a lower sound level, without the distribution blower. NOTE: During the use of this mode, if you keep increasing the temperature dial setting to increase the fire size, the distribution blower will automatically come on when the ESP Temperature reaches 350° F, or 81% output. NOTE: When starting the unit in the "AUTO" mode and switching to "MANUAL", you may switch at any time. Once an ignition cycle is started, it will continue regardless of mode. Room Temperature Mode: This setting will produce a room temperature of 70 degrees with the distribution blower at medium speed. This setting will produce a large viewing fire without a distribution blower operating. Manual Constant burn Mode

17 3-90-04301c Types of Fuel The type of fuel you are burning will dictate how often you have to clean your burnpot. If the fuel you are burning has a high dirt or ash content or you are burning shelled field corn, it may be necessary to clean the burnpot more than once a day. Dirty fuel will cause clinkers to form in the burnpot. A clinker is formed when dirt, ash or a non-burnable substance is heated to 2000°F (1093°C) and becomes glass-like. B. Quick Reference Maintenance Chart Follow the detailed instructions found in this section for each step listed in the chart below. Cleaning or Inspection Frequency Daily Weekly Monthly Yearly Ash Pan Every 5 bags of fuel depending on the fuel type or ash build-up OR X Ash Removal from Firebox Every 5 bags or more frequently depending on the fuel type or ash build-up OR X Heat Exchanger Every 1 ton of fuel OR X Blower, Combustion (Exhaust) More frequently depending on the fuel type OR X Blower, Distribution Every 25 bags or more frequently depending on the fuel type OR X Door Gasket Inspection Prior to heating season OR X Exhaust Path More frequently depending on ash build-up OR X Firebox - Prepare for Non-Burn Season At end of heating season OR X Burnpot - Burning pellets - hardwood Every 3 bags OR X Burnpot - Burning pellets - softwood Every 5 bags OR X Glass When clear view of burnpot becomes obscure OR X Hopper / Hopper Lid Gasket Every 50 bags of fuel or when changing fuel types OR X Venting System More frequently depending on the fuel type OR X NOTICE: These are recommendations. Clean more frequently if you encounter heavy build-up of ash at the recommended interval or you see soot coming from the vent. Not properly cleaning your appliance on a regular basis will void your warranty. 5 Maintenance & Service Shock and Smoke Hazard • Turn unit to the off position, let appliance completely cool and combustion blower must be off. Now you can unplug appliance before servicing. • Smoke spillage into room can occur if appliance is not cool before unplugging. • Risk of shock if appliance not unplugged before servicing appliance. A. Proper Shutdown Procedure C. General Maintenance When properly maintained, your stove will give you many years of trouble-free service.

We recommend annual service by a qualified service technician. CAUTION !

18 3-90-04301c The glass used in your stove is manufactured to exact standards to withstand the high heat of the fire, but like all glass, it must be treated with common sense and care. Never abuse the glass by slamming the door shut or striking the glass with a heavy object. If the glass is broken or damaged, do not operate the stove until it has been replaced. Glass - Replacement If the stove’s glass is cracked or broken, you must replace it before operating your stove. Remove pieces carefully. Replace glass only with Harman® replacement glass; do not use substitutes. Carefully remove damaged glass, gasket material, and hold down clips (set aside). Install the self adhesive 1/4"” gasket material around the front face of the glass. Set the glass panel and gasket gently onto the door. Install the hold down clips and tighten with bolts. Glass - Cleaning Sometimes it will be necessary to clean accumulated ash from the glass surface; allowing this ash to remain on the glass for long periods can result in “etching” due to the acidity of the ash. Never clean the glass while it is hot, and do not use abrasive substances. Wash the surface with cool water, and rinse thoroughly. You may wish to use a non-abrasive cleaner specifically designed for use on stove glass. In any case, dry thoroughly before relighting your stove. Glass Gasket Replace glass only with high temperature mirrored ceramic glass. Inspect door gasket during cleaning and inspection D. Glass Maintenance

19 3-90-04301c Whenever adding fuel, take the opportunity to clean the burn pot. (Weekly at minimum) • Scrape the top holed surface and sides of the burn pot down to auger tube Figure 5.1. It is not necessary to completely remove all material from the burn pot. The excess will be pushed out during the next use. Monthly, or after each ton of fuel burned: • Loosen the (2) wing thumb screws on the lower front angle of the burn pot. Figure 5.2 • Lift off the clean-out cover to open the bottom clean-out chamber. Figure 5.3 • Clean ash buildup from inside the chamber while cover is off. Use the scraper to tap on the top front edge of the burn pot. This will help knock pieces of ash, loosened by the scraping process, down through the holes. It also helps knock scale off of the igniter element. Figure 5.3 The igniter is made to be removable for service by insulated male/female wire connectors. These connections between the hot leads (the wires inside the burn pot) and the cold leads (the wires from the control board) are always pulled to the inside rear of the feeder body. (Not coiled inside the burn pot.) It is very important that these connections are to the inside rear of the feeder body. Also, the extra wire of the igniter wire service loop must be pulled out through the rear of the feeder and tied up so that it will not be damaged by any moving parts. Disconnect the power to the unit before removing cover. Note: The hot lead/cold lead connection must always be pulled to the rear of the feeder body before operation.

24 3-90-04301c With proper installation, operation, and maintenance your appliance will provide years of trouble-free service. If you do experience a problem, this troubleshooting guide will assist a qualified service person in the diagnosis of a problem and the corrective action to be taken. This troubleshooting guide can only be used by a qualified service technician. Helpful Hints 1. Cleaning Burn Pot Whenever your stove is not burning, take the opportunity to scrape the burn pot to remove carbon buildup. A vacuum cleaner is handy to remove the residue. Be sure the stove is cold if you use a vacuum. Carbon buildup can be scraped loose with the fire burning using the special tool provided with your stove. Scrape the floor and sides of the burn pot. The carbon will be pushed out by the incoming fuel. Always wear gloves to do this. 2. Removing Ashes Turn the Temp Dial to number 1 approximately 30 minutes before removing ashes. This will result in a cooler stove and ash pan. Maximum Feed limit settings are not needed in most cases. Operating in the normal range (#4) is recommended when maximum heat output is not required. The ESP probe prevents the stove from being over-fired. Keep the stove free of dust and dirt. STOVE DOES NOT FEED 1. No fuel in hopper. 2. Firebox draft may be too low for sensing switch in feeder circuit to operate. Check for closed doors, loose or missing gasket on doors or hopper lid. 3. Feed motor will not run until the ESP control senses a certain temperature. Maybe you did not put enough fuel or starting gel in the burn pot before manually lighting the fire. 4. Restriction in the hopper or feeder. Remove all fuel and examine. Clear the obstruction. 5. Feed motor has failed. PARTIALLY BURNED PELLETS 1. Feed rate too high. 2. Poor air to fuel mixture. (Check burn pot clean-out cover and air intake). 3. Burn pot or heat exchanger tubes may need to be cleaned. 4. Combination of all the above. 5. #6 status blink: A 6 blink control board status indication is caused by poor or incomplete combustion. The circuit board has the ability to track the combustion through feed settings and ESP temperatures. When the control board has calculated poor or incomplete combustion, it will shut down the unit as a safety feature. (Poor or incomplete combustion is a contributor of creosote which may cause a chimney fire) A 6 blink status may be caused by several things: 1. Blocked or partially blocked flue. 2. Blocked or partially blocked inlet air. a. Backdraft damper on the inlet pipe may be stuck closed. b. If outside air is installed, the inlet cover may be blocked. 3. The air chamber under the burnpot may be filled with fines and small bits of ash. 4. The holes in the burnpot may be getting filled with ash or carbon buildup. 5. Combustion blower fan blades may need cleaned. 6. Fuel restrictions as noted above. SMOKE SMELL Seal the vent pipe joints and connection to stove with silicone. The exhaust vent is the only part of the system that is under positive pressure. FIRE HAS GONE OUT- Check for status light. 1. No fuel in hopper. 2. Draft is too low, blocked flue. 3. Something is restricting fuel flow. 4. Hopper lid not closed properly. 5. Feed motor or combustion blower has failed. SMOKE IS VISIBLE COMING OUT OF VENT 1. Air-fuel ratio is too rich. a. Feed rate too high. b. Draft too low caused by a gasket leak. LOW HEAT OUTPUT 1. Feed rate too low 2. Draft too low because of gasket leak. 3. Poor quality or damp pellets 4. Combination of 1 and 2. Fuel The P43 Pellet Stove is approved for burning any grade of pelletized bio-mass fuel. It is also approved for burning shelled corn in a mixture with wood pellets, up to 50%. It should be noted, however, that higher ash content will require more frequent ash removal, scraping of the burn pot, and may provide less BTU's per pound. The moisture content of pellets must not exceed 8%, and corn must not exceed 15%. Higher moisture will rob BTU's and may not burn properly. Fuel should not be stored within the stove installation clearances or within the space required for cleaning and ash removal. C. Troubleshooting

25 3-90-04301c 7 Reference Material When operating your Harman® P43 Pellet Stove, respect basic safety standards. Read these instructions carefully before you attempt to operate the P43 Pellet Stove. Failure to do so may result in damage to property or personal injury and may void the product warranty. CAUTION: This appliance must be vented to the outside. Due to high temperatures, this stove should be placed out of traffic and away from furniture and draperies. Children and adults should be alerted to the hazards of high surface temperatures and should stay away to avoid burn to skin and/or clothing. Young children should be carefully supervised when they are in the same room as the stove. Clothing and other flammable materials should not be placed on or near this stove. Installation and repair of this stove should be done by a qualified service person. The appliance should be inspected before use and at least annually by a qualified service person. More frequent cleaning will be required. It is imperative that control compartments and circulating air passageways of this stove be kept clean. Disposal of ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled. Soot and fly ash: Formation and need for removal. The products of combustion contain small particles of fly ash. The fly ash will collect in the exhaust venting system and will restrict the flow of the flue gases. Pellet fuels have different ash contents depending on what type of wood has been used to make the pellets. We recommend to clean the system after approximately 1 ton of pellets have been burned and judge from that how often the stove should be cleaned, remember if you change pellets it may change how often you have to clean your stove. When burning wood slowly, the potential exists for creosote to form. The venting system should be inspected periodically throughout the heating season to determine if a creosote buildup has occurred. If a significant layer of creosote has accumulated (3mm or more), it should be removed to reduce the risk of a chimney fire. If a fire occurs, call the fire department, shut down the stove, and evacuate the residence. Before using the appliance, have the venting system thoroughly inspected and replace any damaged components. A. Safety Reminders CAUTION ! THE STRUCTURAL INTEGRITY OF THE MOBILE HOME FLOOR, WALL, AND CEILING/ROOF MUST BE MAINTAINED. CAUTION ! The stove is hot while in operation. Keep children, clothing and furniture away. Contact may cause skin burns. WARNING ! Use of improper fuels, fire starters or altering the stove for higher heat output may cause damage to the stove and could result in a House fire. Use only approved fuels and operation guidelines WARNING ! Keep combustible materials such as grass, leaves, etc. At least 3 feet away from the point directly under the vent termination. WARNING ! Mobile/manufactured home guidelines do not allow installation in a sleeping room.

26 3-90-04301c The Low Draft Pressure Switch is a differential pressure switch that monitors the negative pressure (Draft) in the firebox. If the draft becomes too low for proper combustion, the switch opens, cutting power to the feed motor and the igniter circuits. This switch is connected into the AC (high voltage) wiring. The Control Board/ESP combination is responsible for all high limit safety control. There are 2 high limits, one normal operation high limit and one backup high limit. The control has an automatic diagnostic circuit that continuously monitors the ESP and Room Sensor for faults. If a fault should occur, the control sends a status alert and at the same time the unit goes down to minimum feed/ minimum burn as a safety condition.

27 3-90-04301c Addendum Minimizing Smoke During Loss of Power Using Battery Back-up Harman® strongly recommends installing battery back-up to minimize entry of smoke into the room in the event of power loss. Your pellet/biomass burning appliance relies on a combustion blower to remove exhaust. A power failure will cause the combustion blower to stop. This may lead to exhaust seeping into the room. Vertical rise in the venting may provide natural draft. It is, however, no guarantee against leakage. There are two Harman® approved battery back-up options for your appliance: Uninterruptible Power Supply (UPS) UPS battery back-ups are available online or at computer and office equipment stores. Your Harman® appliance with Rev E or later software available beginning in November 2010 may be plugged directly into a Harman® approved UPS: • The APC (American Power Conversion) model #BE750G and the TrippLite model INTERNET750U are tested and approved. Other brands or models may not be compatible. When power is lost, a fully charged UPS will power a safe, combustion blower only shut-down. Your appliance will pulse the blower every few seconds to clear exhaust until the fire is out. NOTE: The UPS provides safe shut-down only. It is not intended for continued operation. Your appliance will recognize when power is restored. What happens depends on ESP temperature and whether it is equipped with automatic ignition: • In “Automatic” setting, units equipped with automatic ignition will respond to the set point and ESP temperature and resume normal operation. • In “Manual” setting or for units without automatic ignition: • If the ESP is cool, the appliance will remain shut down. • If the fire is out and the ESP is still warm, the feeder may restart. Since the fire is out, the ESP temperature will not rise. The unit will then shut-down, and may flash a six-blink status error. (See ESP error codes) • If the fire is still burning, it will resume normal operation. Contact your dealer if you have questions about UPS compatibility with your appliance. Harman® Surefire 512H Battery Back-up The 512H connects to a 12 volt deep cycle battery that will run your appliance for up to eight (8) hours. It includes a trickle charge feature that keeps your battery charged when power is available. NOTE: If the power is out for longer than battery life, smoke leakage may still occur unless your stove has been safely shut down. CAUTION! Always keep appliance doors and hopper lid closed and latched during operation and during power failures to minimize risk of smoke or burn-back. CAUTION! Use only Harman® approved battery back-up devices. Other products may not operate properly, can create unsafe conditions or damage your appliance. C. Loss of Power Addendum
