PROPER BURN PRACTICES FOR MAXIMUM EFFICIENCY AND SAFETY!
• The flue is one of the most important elements of the furnace. If the flue is not connected properly , and installed according to the manufacturer’s specification s and national and local codes, the unit is not safe and will not burn efficiently. Lack of a proper flue installation will cause the unit to produce more smoke and less heat. See Page 6 of this Operator M anual to ensure proper installation. • Proper use of all electrical components is essential . For instance, the wall thermostat must be hooked up to the furnace and the front draft blower must be in operation at all times. This will increase furnace efficiency and produce more heat output. See Page 1 1 of this Operator Manual for more information. • Wood that is properly cut and stored to dry will produce more BTUs and a higher heat output than wood that has a higher moisture content. Wood with a higher moisture content will create creosote in the chimney and cause flue fires. See Pages 6 and 1 1 for proper wood handling practices. • There should be no alteration of the I gnite Tech Furnace in any way, as this will void the UL391 listing and affect the operation of the furnace. This will also void the warranty of the unit. • Ignite Tech Furnace makes two types of units, indoor as well as outdoor furnaces. The indoor units are manufactured and tested for indoor applications only. They are not meant to go outside of the building but must be placed indoors in a basement or utility room. Any indoor unit placed outside of the building will void the warranty, violate the safety listing, and will not produce the maximum efficiency possible. For out door applications please use unit HD 90X .

General Information ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND; DRY WOOD WILL PRODUCE MORE BTU OUTPUT AND LONGER BURN TIMES. The Ignite Tech Furnace is an airtight central solid fuel outdoor furnace engineered to accommodate the heating requirements of the average sized building , even during winter’s coldest months. It is constructed of high grade, heavy gauge steel and is continuously welded to assure the utmost in structural strength. The insulated firebox will accommodate a log up to 34 inches in length. In addition, the heat exchanger is lined with firebrick to ensure many years of energy efficient service. The design of the secondary combustion chamber increases fuel efficiency by creating a “secondary burn” of smoke and wood gases before they are vented up the chimney. By sending the gases back through the secondary combustion chamber, less fuel is wasted, the furnace burns at a higher efficiency, and for longer burn times. The cast iron door is custom fitted to provide an airtight seal, greatly extending the burn time and ensuring maximum efficiency in fuel consumption. The heavy-duty cast iron grates aid in convenient ash removal and reduce maintenance; the insulated wrap-around sides are designed for maximum heat transfer. For total comfort and convenience, a thermostatically controlled 1800 CFM circulation blower system has been installed. The blower draws the cold air from the building , across the heat chamber before going through the hot air duct and returning the warm air in to your building . This fully automatic blower furnishes rapid heat dispersement to your building , minimizing recovery time. Average burn time per load of fuel is 2 to 12 hours depending on wood or coal type and condition, desired temperature within the building , size of the building, and amount of fuel. We have incorporated all of these features as standard equipment, offering you the most efficient, durable and affordable appliance possible. Abnormally cold weather could reduce the burn time. Your Ignite Tech Furnace is designed to be either a supplemental or central heating source for your building . This wood and coal burning furnace may be installed in parallel with a properly operating electric, gas or oil-fired central furnace, listed or certified in accordance with a nationally recognized safety standard, and within clearances specified on Ignite Tech Furnace nameplate. When in a parallel installation the static pressure of the central furnace plenum may not exceed 0.15 water column inches and the maximum setting on central furnace limit switch is 182°F. With the Ignite Tech Furnace in an “Interconnection Arrangement” your furnace should be upstream of the central furnace. The Ignite Tech Furnace warm air supply should never be connected to return air for the central furnace. A qualified installer should perform the installation. This is a wood and coal burning furnace – it cannot be turned “off and on” to control the furnace temperature like gas or electric furnaces. Once the fire is established, it has to burn until all of the fuel is consumed .

Before beginning your installation, consult with local authorities regarding the codes governing all such installations. DO NOT connect your Ignite Tech Furnace to any flue that is servicing ANY other appliances. The Ignite Tech Furnace may be placed outdoors or indoors. If outdoors, it must be placed on a level, non-combustible base, preferably a 4’ x 8’ concrete pad, as close to the building as clearances to combustibles permit – do not place the furnace more than 25 feet from the building . The furnace must be connected to a grounded electrical circuit with access to a backup generator (2000 watt minimum). If locating the furnace more than 10’ from the building , a minimum of 6’ of Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required. If installing indoors, your furnace must be placed on a non-combustible floor. Air for combustion must be provided into the room where the furnace is located. Allow air free access to furnace for combustion and ventilation. Maintain the following clearances: • Front = 48 inches • Rear = 31 inches • Sides = 12 inches • Heat Duct = 6 inches for the first 16 inches from the back of the furnace, and 3 inches beyond Maintain the “10/2 Rule” for the flue, which says the flue must be 2 feet higher than any part of the building or peak of the roof within a horizontal distance of 10 feet. The 2 foot height does not include the cap. See diagram below.
2 Foot Minimum
10 Feet
4’ x 8’ Level Concrete Pad
Class “A” HT 2100 All Fuel 6 inch Chimney Pipe is required for optimum performance and must maintain a 2 inch clearance from combustibles. The Ignite Tech Furnace will ship with an anchor plate installed . If the anchor plate provided with your furnace does not fit the chimne y your local dealer has in - stock, please call our toll free number for assistance : 1-800-875-4788 . IMPORTANT: Please keep in mind that different chimney manufacturers’ pipe will not interchange with other brands. A tube of high-temp silicone caulk is included with your furnace. Before using the silicone to install the anchor plate to the top of your Ignite Tech Furnace, ensure the chimney you purchased will f it the anchor plate. Guy wire brackets are attached to the sides of the Ignite Tech Furnace. A heavy gauge of stainless steel wire can be purchased from a local hardware store to use as guy wire to help support your chimney. Attach the appropriate chimney pipe lengths to the adapter plate finishing with a chimney cap. IMPORTANT: Your furnace requires its own chimney system and cannot share a flue with any other product. DO NOT USE GALVANIZED OR BLACK PIPE AS A FLUE FOR YOUR FURNACE.

Once you have met local requirements governing the installation and positioning of the furnace, install the Electrical Control Kit. Open the Electrical Control Kit and confirm that all items were shipped with your Ignite Tech Furnace. IMPORTANT: ENSURE THE POWER CORD IS PLUGGED INTO A GROUNDED ELECTRICAL SUPPLY. D O NOT connect the furnace to your ductwork at this time. Build a small fire – DO NOT fill the firebox to full capacity during the initial firing. Your new furnace has a protective coating of oil or paint on the surface, which could produce smoke or odors during the initial firing and will burn off. Allow adequate ventilation during this initial, break-in firing to let any odors escape. This initial firing also allows the metals to cure. After successfully completing the initial firing, you are ready to attach the hot air duct and cold air return to complete your installation. See diagram below.
You must install the wall thermostat for the furnace to operate. When the wall thermostat calls for heat, the draft motor will engage, allowing combustion air to flow into the firebox. This causes a hotter fire, increasing the heat in the heat chamber. When the building reaches the selected temperature on the wall thermostat, it will disengage the draft motor and the fire in the firebox will reduce to a low burn until the thermostat calls for another heat cycle. The fan limit control is factory pre-set at 160° as the “ON” temperature setting and 100° as the “OFF” temperature setting. This means when the heat chamber reaches 160°, the blower will turn on; when the chamber cools, the blower will turn off. This process is called a heating cycle.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, CALL IGNITE TECH AT 1-800-875-4788.
BYPASS DAMPER: The bypass damper has several purposes: starting the fire, improving the efficiency, and cleaning the chimney. When starting a fire in the Ignite Tech Furnace, you must pull the rod out for a stronger draft during ignition. Once the fire has started, close the bypass, which allows the secondary combustion chamber to engage, increasing the furnace’s operation to peak efficiency. If the bypass rod is not closed during operation, the furnace’s efficiency will be greatly reduced, allowing the heat to escape up the chimney. Finally, when cleaning the chimney, the rod must be pulled out to allow any build-up in the chimney to fall into the firebox. THIS UNIT IS NOT TO BE CONNECTED TO A CHIMNEY FLUE THAT SERVES ANOTHER APPLIANCE.
5
Chimney Location and Clearances: Requires Class “A” HT 2100 All Fuel 6 ” Chimney
The furnace requires a minimum of 6 feet of chimney. When positioning the furnace, maintain the “10/2 Rule” for the chimney – In order to determine proper chimney height above the roof, measure from the side of the chimney horizontally. As you move up the chimney, the length of the measurement increases. Once this measurement reaches 10 feet, this height on the chimney is your base height. The chimney must be 2 feet taller than the base height. If the chimney is closer than 10 feet from the peak of the roof, the chimney must be 2 feet higher than the peak of the roof. The 2 feet above the base height does not include the cap. The furnace must be placed on a level, non-combustible surface or 4 foot x 8 foot concrete pad. Do not level from top of furnace. The front is 1/2” taller than the back for water run off. See diagram below.
2 Foot Minimum
10 Feet
4’ x 8’ Level Concrete Pad
By definition, “Class A” refers to either a lined masonry chimney or all fuel factory-built chimney. Although experts have expressed differing opinions as to which system is the best, it is a matter of what you find most suitable. Regardless of your choice of chimney type, a minimum 6 -inch diameter chimney is needed. In order to create the most efficient draft, the chimney size should not exceed 12 inches, with a maximum .08-inch water column draft. The flue draft can be measured with the use of a draft gage or manometer. Wood Storage and Care: KEEP WOOD COVERED AT ALL TIMES. This cannot be over emphasized. Wood stored/stacked, uncovered, exposed to rain and snow has a higher moisture content, causing the formation of creosote, excess smoke, and it takes longer to ignite as well as producing poorer ires with lower sustained BTU output. Unseasoned wood ends up costing more in time trying to achieve and maintain proper temperatures in the firebox, while using more wood with less heat output. Covering the woodpile will keep it dry and offer you the hottest fires with the greatest BTU output. If you store the wood near your furnace, be sure to maintain proper clearance from the furnace to prevent a fire hazard. DRY WOOD WILL PRODUCE HOTTER FIRES AND INCREASE BTU OUTPUT.

• Installation is to be performed by a qualified installer. • Always consult local building inspectors for codes concerning the installation of your furnace. • Always have access to a backup generator, 2000 watt minimum. • Use Class “A” HT 2100 All Fuel 6 Inch Chimney for your I gnite Tech Furnace.
• Never use galvanized pipe in your flue connection. • Inspect the flue periodically for structural integrity.
• Clean the flue regularly to prevent creosote accumulation. • Never use chemicals or gasoline to start or maintain your fire. • Never burn garbage, oil, trash, or gasoline in your furnace. • Never leave the fuel door or ash drawer open during operation. • Remove ashes on a daily basis, before ashes reach the grates, to ensure proper air flow. • Never use wet, unseasoned wood or wood exposed to a recent rainfall. Doing so causes a rapid accumulation of hazardous creosote, which is a proven cause of flue fires. • Never burn plastics, wood products containing glue, or wood that has been treated with chemical preservatives in your Ignite Tech Furnace. The combustion of these substances may release harmful, toxic gases. • NEVER UNPLUG THE FURNACE FROM THE POWER SOURCE. THIS WILL CAUSE THE FURNACE TO OVERHEAT. If it is too warm in the building , lower the temperature on the thermostat; reduce the spin draft to allow less airflow into the firebox; and/or use less fuel (wood or coal). • Never leave the ash drawer or fuel door open in an attempt to regulate the fire. This will overheat the furnace and void the warranty. • Do not connect this unit to a chimney flue serving another appliance. • Refer to nameplate on furnace for additional information. • DO NOT operate with flue draft exceeding .08 water column inches (19.9 Pa). • DO NOT store fuel or other combustible materials within marked installation clearances. • Inspect and clean flues and chimney regularly. • DO NOT operate your furnace with the fuel door or ash drawer open. DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate materials. WARNING: RISK OF FIRE
Hot Air Duct and Cold Air Return Installation: Included with your I gnite Tech Furnace:
• One 10 inch starter collar • One 12 inch starter collar
NEVER reduce the 10 inch hot air or 12 inch return air, as this will affect the air flow and the furnace will not operate properly. NEVER draw cold outside air into the blower housing. By doing so, the furnace’s heat chamber will not reach the necessary temperature to heat the building.
7
The duct work should be designed so the external static pressure does not exceed 0 .2 water column inches, while developing air velocities of 600 feet to 1,000 feet per minute in the main trunk duct and 400 feet to 600 feet per minute at the registers. The heat outlet should never be less than 10 inches round or 79 square inches. The Ignite Tech Furnace must be installed with a cold air return system. The system must be a minimum of 12 inches to readily transfer the cold air back to the furnace. If desired, a cold air filter box may be constructed with a minimum opening of 225 square inches. A foundation window is an excellent location for running the hot air duct vent as well as the vent for the cold air return. The cold air return is an integral part of the system and must be used when installing the furnace. Failure to use cold air return will pressurize the building causing the furnace to not work properly. If a basement window is not available, you may access the building through a window, wall, or crawl space for both the plenum and air return. Run the thermostat wire (not supplied) from the 2 posts located on top of the control center transformer. NOTE: You may run the thermostat wire and power cord through the return cold air duct, or you may access the hole from the bottom of the blower housing cover. THE HOLE MUST BE SEALED AFTERWARD, REGARDLESS OF ROUTING CHOICE.
Burying Ductwork: DO NOT BURY FLEXIBLE DUCT.
To bury the ductwork, use schedule 40 or 80 PVC or black plastic DUAL WALL CULVERT PIPE with smooth inner walls. Dig a trench to accommodate both the heat duct and the return air duct. The trench must be a minimum of 24 inches deep. To further ensure efficiency, minimize heat loss, and prevent moisture formation, line the trench with 1 inch pink Styrofoam insulation sheeting on the sides and bottom of the trench. The duct run should not exceed 25 feet. If the run exceeds 25 feet, you run the risk of reducing the furnace’s efficiency and airflow. DO NOT USE FLEXIBLE HOT AIR DUCT INSIDE PVC OR CULVERT PIPE. ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND. DRY WOOD WILL PRODUCE MORE BTU OUTPUT AND A LONGER BURN TIME. The diagram on page 9 shows typical installations through a foundation window, crawl space, or wall. Notice that the heat duct and return air duct do not contain any 90° elbows. The use of 45° or less is advised for proper air delivery. IF 10 INCH FLEX DUCT IS USED, IT MUST NOT BE EXPOSED TO THE OUTDOORS. IT IS FOR INDOOR USE ONLY. WARNING: RISK OF FIRE! DO NOT USE ANYTHING OTHER THAN 250° F-RATED FLEX DUCT! IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, CALL IGNITE TECH AT 1-800-875-4788. T ypes of Installations : Your Ignite Tech Furnace is designed to be a supplemental or central heating source for your building. This wood/coal burning furnace may be installed in parallel with a properly operating electric, gas, or oil-fired central furnace that is listed or certified in accordance with a nationally recognized safety standard within installation clearances as specified on the Ignite Tech Furnace nameplate. When in a parallel installation the static pressure of the central furnace plenum may not exceed .15 water column inches, and the maximum setting on central furnace limit switch is 182° F. With the HD90X wood and coal burning furnace in an “Interconnection Arrangement” your Ignite Tech Furnace should be upstream from the central furnace. The Ignite Tech Furnace warm air supply should never be connected to the return air for the central furnace. A QUALIFIED INSTALLER SHOULD PERFORM INSTALLATION. CENTRAL DUCT CONNECTIONS: A qualified professional should do the installation. Maximum run should be 25 feet. A duct run in excess of 25 feet will greatly restrict the air flow and heat output, therefore is not recommended. When connecting the Ignite Tech Furnace to a central duct system, avoid 90° elbows. As with any furnace, the more turns and branches in the ducting limit the airflow delivery. DO NOT USE FLEX DUCT OUTSIDE.

Run 10 inch insulated galvanized hot air duct from the outside furnace through a window or wall of the building . Once inside, you may use 250º Fahrenheit rated insulated flexible hot air duct to connect the central duct system for the building . When using flexible duct inside the building , it must be pulled tight with no offsets or elbows to prevent turbulence and slowdown airflow. Connect the duct with a 45° elbow or at an angle so the hot air from the Ignite Tech Furnace is delivered down stream. This will ensure proper airflow into the duct system. Avoid delivering the hot air through the air conditioning coil, as this will cause an obstruction, reducing the amount of heat output. DO NOT REDUCE THE SIZE OF THE HOT AIR DUCT. As with any furnace, longer runs and more turns and branches in the ducting greatly reduce the airflow and heat output. Use of 90° elbows is not recommended. The 12 inch cold air return duct must run to the building to prevent pressurization of the building . Failure to connect the cold air return will cause the furnace not to operate. NEVER REDUCE THE SIZE OF THE RETURN. Reducing the size of the cold air return will restrict the hot air flow and put excess pressure on the blower motor. You may terminate the cold air return where you enter the building . This will provide adequate circulation within the building . See diagram below .

NO DUCT WORK INSTALLATION CONNECTION: A qualified professional should do the installation. Cold air return must be installed in all cases, even those without ductwork. When there is no duct system to connect to the hot air duct, keep in mind: • You must separate the hot air duct from the cold air return. Ideally, locate each at opposite ends of the building . If you don’t, the air will not flow evenly throughout the building . This method will work well on building built on concrete slabs and help create a good airflow. • In building s with a basement, you may run the hot air duct into the basement and pull the cold air return from the main floor, this will create a perfect air flow, since hot air rises. The cold air return must be connected, even if the building does not have ductwork. If you don’t connect the cold air return, the furnace will not be able to heat the building . See diagram below .

Outside c ombustion air may be necessary for an indoor installation if: • The solid-fuel-fired appliance does not draw steadily, smells, experiences smoke roll - out, burns poorly, or back-drafts whether or not there is combustion present. Opening a window slightly on a calm day alleviates these symptoms. • The building is equipped with a well-sealed vapor barrier and tight fitting windows, and/or has any powered devices, which exhaust building air. • If fans are installed in the storage area they should not create negative pressures in the room where the solid fuel-burning appliance is located. • There is excessive condensation on windows in the winter. • A ventilation system is installed in the building. CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION. BURN WOOD AND COAL ONLY! First Wood Fire: Set the wall thermostat to 90°F. Check to make sure the spin draft is wide open to allow oxygen into the firebox. Make sure switch on the wall thermostat is in the HEAT position. Adjust slide cover on draft blower to an opening of approximately ⅜ inches. Place several crumpled newspapers on the grate with some dry kindling layered on top of the papers, then ignite the newspaper. When the kindling is burning, add several small pieces of wood, allow wood to fully ignite. After about 20 minutes the fire should be established, allowing you to add more wood – do not overload which would smother the fire. Add more wood slowly, so the flames have time to engulf the fresh wood. Once the fire is burning and there is a glowing ember bed, adjust the draft to achieve desired burn pattern. Learning how to adjust the draft to maintain the desired temperature for your building may take several days. After a short time you will know which settings and adjustments work best for your building . Set the wall thermostat to the desired building temperature. Do not over-fire the furnace. Over-firing by overloading/over fueling the furnace causes the metal to superheat and expand, then cool rapidly, which causes cracking, therefore voiding the warranty. Over-firing or abuse can easily be determined upon inspection. It will take about 40 minutes to establish a bed of hot embers. Once you have achieved the hot ember bed, add larger pieces of firewood and push the bypass rod all the way in. Within 30 to 40 minutes, adjust the spin draft to obtain optimum performance. Finally adjust the wall thermostat and draft blower cover to a comfortable setting. See diagram on page 1 4 . NOTE: Your new Ignite Tech Furnace is capable of producing a very high BTU output. Do not fuel your furnace to capacity upon initial firing. It’s recommended that you become thoroughly familiar with your Ignite Tech Furnace before operating at full capacity. The new steel and metal components of the furnace have a protective coating or paint on the surface which could produce an odor during the break in period. Adequate ventilation within the building and furnace room or area is recommended during the initial firing and break in period to accommodate this possibility. Your new Ignite Tech Furnace is classified as having airtight construction. This type of design should enable you to experience an average burn time between 6 and 12 hours per full load of fuel (dry, seasoned hardwood). However, abnormally cold weather may reduce the burn time somewhat, but if your burn cycle is significantly less, for instance, 2 to 4 hours, you are over-firing your furnace. This type of occurrence is usually symptomatic of heat demands in excess of furnace capacity. Contact an authorized professional to determine if your Ignite Tech Furnace has been improperly sized for your building . Loading Wood: When opening the fuel door during operation, always pull the bypass rod all the way out before opening the fuel door, wait 10 seconds after releasing the first latch, then open the door the rest of the way. The dual latch system has been incorporated as a safety feature, designed to reduce the possibility of gaseous ignition. Laboratory testing has determined that when incomplete combustion occurs the partially spent fuel sometimes concentrates large amounts of potentially hazardous gases within the fire chamber. If the door is opened suddenly under these conditions, the oxygen may combine with these gases and cause ignition referred to as “back flash.” Use EXTREME CAUTION when opening the fuel door. When reloading the furnace, spread embers evenly over the grate. Place smaller pieces of wood or coal on the hot embers and layer larger pieces on top of them. Finally, due to the wide variety of temperature ranges during the winter, you may experience periods when it is not necessary to fully load the fire chamber in order to maintain an overnight burn. Your Ignite Tech Furnace will operate at the highest efficiency by adding fuel in amounts needed to maintain comfortable temperatures in your building .

IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, CALL IGNITE TECH AT 1-800-875-4788. First Coal Fire: Burning coal is much harder than burning wood. There is more care and work in building and maintaining a coal fire than a wood fire. Anthracite is the best coal to burn, due to its long even burn with higher heat output and clean burn quality but is more difficult than Bituminous coal. The size of coal is important. “Nut” coal sizes of 4 inches for Bituminous and 2¾ to 4½ inches for Anthracite coal are recommended. Never use coal other than the sizes recommended. If the coal is too small it will smother the fire and if it is too large the coal will not burn well. When burning Bituminous coal, start the fire with wood (as described above). Always use dry kindling, as this will provide a hotter fire and add small pieces of wood until you get a good hot ember bed. At this point add a small amount of coal. When the coal is hot enough to ignite, add small amounts at a time, so as not to smother the fire. Keep in mind that Bituminous coal will require more maintenance as this type of coal will produce more soot, requiring more frequent cleaning to prevent buildup. Also make sure that the spin draft control is wide open to establish the correct burn pattern. When adding coal to Bituminous fires always add coal to the center of the bed creating the cone effect. Bituminous coal is more volatile and adding coal to the center of the bed causes the flames to drive off the volatile gases. Remember that no two installations and chimney set-ups are the same, so be prepared to experiment until you achieve the desired results. Always allow enough air to the firebox so that volatile gases are properly burned. When adding fuel, remember to break up the cone with a poker if it has formed a crust, but be careful to avoid mixing the coal as this can form clinkers. Shake the grates a couple times so as not to disturb the fire. Excessive shaking wastes fuel and exposes the grate to extreme heat, which will cause warping or burnout. For overnight burn operations, follow the above instructions and adjust the chimney damper and set the thermostat. When burning Anthracite coal, start the fire with wood (as described above). Add layers of coal making sure not to smother the fire, the third layer should be a little heavier, but should not to extend above 2 inches below the top of the brick in the firebox . Before adding more fuel, be sure to leave a red spot in the center of the bed. This hot spot will help ignite the gases given off the new charge. A deep charge will give a more even heat and a longer fire. It may take up to a couple hours before the whole bed is fully ignited. When the fire is established and the building is becoming warm, you may adjust the damper. It may still take some experimenting with the wall thermostat to ensure proper operation, as no two installations are the same. Once the coal bed has reduced to half its original depth it is time to add fuel to the furnace. At this point pull out the bypass rod and turn up the wall thermostat. This will allow the fire to burn off the accumulated gases. Open the fuel door, using a small rake or hoe pull the coals towards the front of the bed, trying not to disturb the fire too much. Next, add coal to the back, being careful not to seal off the top. Keep the ash drawer cleaned out to ensure good airflow. You may want to start this banking process early before leaving the building so that you may make proper adjustments after the fire is well established. WARNING: It is unsafe to load any type of coal within 2 inches of the top of the firebrick . Load fuel carefully or damage may result. NOTE: Do not burn coke, charcoal, highly volatile Bituminous coal, sub Bituminous, lignite or cannel coal (sometimes called channel coal or candle coal). Never burn wax or chemically processed logs, such as fire logs as their use is for fireplaces only. Please follow all guidelines in this manual concerning wood and coal burning applications due to safety concerns and to maintain warranty coverage. BURN WOOD AND COAL ONLY! Fuel Recommendations: For the HD90X model, heat resistant gloves are recommended when loading the furnace. Only use dry, seasoned hardwoods in your Ignite Tech Furnace rather than high resin woods such as pine. Firewood should be cut at least one full season prior to the time of its intended use for optimum heat output. Firewood should be stacked to provide a free flow of air between the logs; this allows the wood to season faster. If wood is stored outdoors, it should be completely covered year round to protect it from moisture and exposure to the elements. Use extreme caution when opening the ash drawer and fuel door during operation, temperatures can exceed 300° F. Wait at least 10 seconds after releasing the first latch, then proceed to the fully open position. The dual latch system has been incorporated as a safety feature, which was designed to reduce the possibility of gaseous ignition. Heat resistant gloves are recommended when opening the fuel door, regulating the spin draft or emptying the ash pan.

DISPOSAL OF ASHES: Heat resistant gloves are recommended. In order to remove ashes from your Ignite Tech Furnace, slide the ash drawer to the rear of the furnace. Remove the ash drawer from the furnace and dump the ashes into 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 metal container until all cinders have thoroughly cooled. Remove the ashes from your Ignite Tech Furnace at least once a day, or as often as necessary to ensure the ashes do not accumulate to the height of the grates. If ash build-up occurs at grate level, it will cause premature failure of the grate system, voiding the warranty on the grates. Unacceptably high temperatures will result because the ashes have restricted the flow of cooling air beneath the grates. This flow of air was designed to not only cool the grates, but to also provide warmed air for better combustion. If the ash level is improperly maintained the firebox will be starved of combustion air, greatly reducing the efficiency and heat output of your Ignite Tech Furnace. ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND. DRY WOOD WILL PRODUCE A HIGHER BTU OUTPUT AND A LONGER BURN TIME. HEAT DUMP AND FUSE LINK SYSTEM: The Ignite Tech Furnace has a patented automatic safety feature, the Heat Dump Release System. In the case of a power failure, the heat dump release will open the spring-loaded lid when the internal furnace temperature reaches 370° F. The heat sensitive fuse link, located within the top of the heat chamber, causes the lid to open, allowing the excess heat to escape. This safety feature is designed to activate before any extreme heat can damage the furnace. In the case of a power failure, connect your Ignite Tech Furnace to a generator immediately. If the heat dump release lid should open, do not continue to burn the furnace. DO NOT UNPLUG THE FURNACE. Close the draft dampers and set the wall thermostat to the lowest possible temperature. DO NOT add fuel (either wood or coal), which will allow the fire to die. Pull out bypass rod. After the electricity is restored, replace the fuse link before resuming normal operation. REPLACING THE FUSE LINK: Remove the hex nut on top of the release lid and pull the bolt down through the lid. Remove the separated fuse link pieces and connect the new fuse link to the shaft inside the furnace heat chamber. Connect the other end of the fuse link to the bolt that goes through the lid. Feed the bolt through the lid and replace the hex nut onto the bolt on top of the lid. As a precaution, always have a replacement fuse link on hand. WARNING: Never disengage the patented Heat Dump Fuse Link feature. This will void all warranties. Never put anything on top of the release lid. The area must be kept free of any obstructions. A visual inspection by factory personnel can easily determine if the proper steps were taken if a furnace over-heats. If the furnace is found to be deliberately improperly used, all warranties will be void.

Draft Blower and Spin Draft: The front draft blower plays an important role in the operation of your Ignite Tech Furnace. When the wall thermostat calls for heat, the draft motor turns on and supplies fresh air into the firebox producing a hotter fire, which in turn provides more heat in the heat chamber. The heat is then sent through the duct system throughout your building . When the wall thermostat temperature is met, the draft blower shuts off until the thermostat calls for heat, beginning the cycle again. The draft blower has a slide cover located on the side of the motor that is factory preset, with an opening of approximately 3/8”. The cover should be fully closed only when there is a power failure and electricity is lost. With the cover closed, no air is introduced into the firebox, then the fire dies, preventing the furnace from possible overheating and damage. The manual combustion air spin damper control on the ash drawer should be set with a 1/8 inch gap. To begin, adjust slowly by making 1 rotation at a time to find the correct air setting.

Creosote Formation and Need for Removal: When wood is burned slowly, it produces compounds in exhaust smoke, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cooled chimney flue of a slow burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely dangerous fire in the chimney. The chimney connector and the chimney should be inspected at least twice monthly during the heating season to determine if a creosote build-up has occurred. If creosote has accumulated it should be removed to reduce risk of a chimney fire. Creosote Prevention: To help prevent the formation of creosote within the flue, ALWAYS BURN DRY, SEASONED WOOD. Dry wood burns hotter, allowing flue gases to maintain temperatures above 212°F which should reduce the formation of creosote in the chimney. If the flue gas temperature falls below 212°F, condensation occurs causing creosote formation and accumulation within the chimney. As an added precaution, periodic chimney inspections are recommended during the heating season to determine if creosote formation has occurred. For safety and efficiency, it is recommended that the chimney system be inspected and cleaned prior to each heating season. Power Failure: In case of power failure, to prevent your Ignite Tech Furnace from over-heating and causing damage to the electrical components, follow these steps:
• Ensure that the bypass rod is pulled out, allowing heat to go up the chimney. • Close the spin damper control on the ash drawer. • Close the slide cover on the side of the draft motor. • Do NOT add more fuel (coal or wood) to the firebox.
There is no warranty on electrical components damaged due to power failure.

CAUTION: • INSPECT FLUE PIPES, FIREBOX, STOVE PIPE, CHIMNEY AND DRAFT BLOWER JOINTS AND SEALS REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES ARE NOT DRAWING INTO, AND CIRCULATED BY THE AIR-CIRCULATION SYSTEM. • CLEANING OF THE FIREBOX, STOVE PIPE, CHIMNEY AND DRAFT BLOWER (IF USED), IS ESPECIALLY IMPORTANT AT THE END OF THE HEATING SEASON TO MINIMIZE CORROSION DURING THE SUMMER MONTHS CAUSED BY THE ACCUMULATED ASH. • Do not use chemicals to start the fire. • Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate materials. At the beginning of each heating season, take time to throughly check your furnace and chimney system. Make sure there are no leaks where the metal panels are joined or at the caulk lines. Should you find a leak, high-temp silicone will correct the problem. Check the door for signs of rust. Should rust develop, lightly sand, with sandpaper or steel wool, the surface and follow up with black, high temperature paint to keep the door looking new. Check the gaskets, if they are frayed and burnt, replace the gasket. Check the firebricks for breakage or crumbling, and replace as needed. Check the chimney pipe for signs of creosote formation, if you find creosote, thoroughly clean the chimney system replacing the chimney cap securely so rain or snow does not run down the chimney into the firebox. If the cap is removed for any length of time when the furnace is not in use, cover the pipe so no moisture gets into the firebox. Check the chimney cap for holes or loosened connections, replace and secure as necessary. Check the grates for signs of wear and replace as needed. Check the heat duct and cold air return to be sure they have not become loose or been damaged. If so, tighten or replace as needed. Check ductwork for any air leaks. Remove any accumulated ashes at the end of the season. By following these procedures, your furnace will provide many years of trouble-free service.
