PROPER BURN PRACTICES FOR MAXIMUM EFFICIENCY AND SAFETY!
• The chimney is one of the most important elements of the furnace. If the chimney is not connected properly and installed according to manufacturer’s specification and national and local codes, the unit is not safe and will not burn efficiently. Lack of proper chimney installation will cause unit to produce more smoke and less heat output. See Pages 7-9 of this manual 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 draft blower operation may NOT be altered. This will increase furnace efficiency and produce more heat output. • Wood that is properly cut and stored to dry will produce more BTUs and higher heat output than wood that has a higher moisture content. Wood with higher moisture content will create creosote in the chimney and cause flue fires. • There should be no alteration of the Shelter Furnace in any way, as this will void the UL391 safety listing and affect the operation of the furnace. This will also void the warranty of the unit. • Shelter 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 the house but must be placed indoors in a basement or utility room. Any indoor unit placed outside the home in a shed or building will void warranty, violate the safety listing, and will not produce the maximum efficiency possible with this unit. For outdoor applications please use m odel SF4200.

General Information The Shelter EPA- Certified Furnace has been engineered to accommodate the heating requirements of the average sized home, even during winter’s coldest months. It is constructed with high grade, heavy gauge steel and is continuously welded to assure the highest structural strength. In addition, the firebox is lined with insulated stainless steel panels 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. The cast iron doors are custom fitted to provide an airtight seal, greatly extending the burn time and ensuring maximum efficiency in fuel consumption. The heavy gauge cast iron grate, designed for maximum heat transfer, allows for convenient ash removal and reduced maintenance. For total comfort and convenience, a thermostatically controlled D raft Blower and fan limit controlled C irculation B lower are included. These fully automatic components disburs e heat throughout your home, minimizing recovery time when the wall thermostat demands heat. All of these features are standard, offering you the most efficient, durable and affordable indoor wood burning furnace. Efficiency was determined using the higher heating value of the fuel per B415.1-10 testing requirements. Dry seasoned wood will develop greater BTU output. A well-insulated dwelling will always lead to better results and overall improved fuel usage efficiency. Your Shelter Furnace is designed to be either a supplemental or central heating source for your home. This wood 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 the 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 Shelter Furnace in an “Interconnection Arrangement” , your furnace should be upstream of the central furnace. The Shelter Furnace warm air supply should never be connected to return air for the central furnace. A qualified installer should perform the installation. IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, DO NOT RETURN TO THE DEALER . THE DEALER DOES NOT HAVE REPLACEMENT PARTS . CALL : 1-800-875-4788. Forced Hot Air Circulation: The plenum size of your Shelter Furnace must not be reduced to less than 100 square inches, and must provide a minimum of 18 inches between the top of your Shelter Furnace and the main trunk connection. Do not modify the outer shell of the furnace at any time. The plenum attached to the furnace must be constructed of metal. The warm air supply duct system should be constructed of materials with a minimum temperature rating of 250° Fahrenheit. Clearances: Unit must be placed on a non-combustible floor. This floor must extend at least 16 inches in front, 8 inches on either side of fuel loading and ash removal doors, underneath the chimney connector and must extend 2 inches on either side of the chimney connector. The furnace must maintain the following clearances to combustibles: • Heat plenum = 2 inches • Chimney connector = 18 inches • Front = 48 inches • Rear = 12 inches • Sides = 6 inches • Main furnace = 12 inches These are minimum clearances and should be strictly followed. In the case of a power outage, a dangerous level of heat accumulation may develop. Do not store fuel or other combustible materials within installation clearances.

Location and Installation
NOTE: Before beginning installation, consult proper local authorities regarding local codes governing all such applications and installations. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. Your furnace must be placed on a non- combustible floor. Position the furnace as close to the chimney as possible. Air for combustion must be provided into the room where the furnace is located. Allow air free access to the furnace for combustion and ventilation. Garage installs are not recommended due to National F ire C odes. Consult with your local code and insurance company. When installing an indoor furnace, the heat plenum coming off the top of the appliance can only go up or horizontal to connect into the main supply duct. Never run the plenum down as this will create a heat buildup in the furnace causing the blower to short cycle and damage the blower motor and will not be covered under warranty. This is not a down draft furnace and not to be installed as one. If you do not have a basement and the plenum cannot be put in the ceiling, then we recommend our Shelter outdoor furnace model SF42 00 . RECOMMENDATION: Purchase Chimfex™ Dry Chemical Chimney Fire Extinguisher which are available at most dealers and home improvement stores. Smoke and Carbon Monoxide detectors should be installed on all levels of your home. Having a fire extinguisher in the furnace room or area is strongly recommended.

Chimney Types and Recommendations See Diagram on page 8. Safety requirements demand that your Shelter Furnace be connected to “Class A” HT2100 All Fuel, or stainless-lined masonry chimney ONLY. 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, for models SF 1000, a minimum 6-inch diameter chimney is needed. In order to create the most effective draft, the chimney size should not exceed 12 inches, with a maximum .08 water column inches of draft. The flue draft can be measured with the use of a draft ga u ge or manometer. The stovepipe required to connect the furnace to the chimney should be a minimum of 24 gauge black or stainless steel. NEVER USE GALVANIZED PIPE. Horizontal run should not exceed 5 feet and should have a minimum rise of 2 inches per foot. No installation should have more than 2 elbows, a 45° elbow is recommended over a 90° elbow. As a safety precaution, all pipe selections should be fastened together with a minimum of 3 sheet metal screws. For your convenience, the crimped male ends of the pipe should point toward the furnace to form drip-free connections, thereby reducing the possibility of creosote leakage from the joints. Always install a "T" with clean-out cap to the chimney outlet on the back of the furnace. This allows for easier cleaning of the chimney system. When using a masonry chimney, you must line the chimney with a stainless steel liner. The stainless steel liner will keep the chimney temperature hotter for better draw and significantly reduce the creosote formation in the chimney. If using this method, a 6-inch stainless liner should be used for SF 1000.
7
The termination cap should be designed to inhibit down-drafting without restricting the exhaust discharge.
For the best draw the chimney termination should be at least 2 feet above the highest point of the roof that is within a 10 foot radius of the chimney.
When using a brick chimney, you must line the entire chimney with stainless steel liner. The liner must be 6” for the SF 1000. The diameter of the chimney stack should be consistent throughout the length of the chimney.
The chimney size should be at least as large as the exhaust stack on the furnace , but not more than twice its size.
The chimney stack should have a built-in airtight clean out. WARNING: Do not operate with clean out uncapped.

WARNING : RISK OF FIRE:
• Do not operate with flue draft exceeding .08 water column inches (19.9 Pa). • Do not operate with fuel loading or ash removal doors open. • Do not store fuel or other combustible materials within marked installation clearances. • Inspect and clean flues and chimney regularly. DANGER: Risk of Fire and Explosion. Do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate materials. WARNING: • NEVER use galvanized pipe in your chimney connection, it produces poisonous gases when subjected to extreme temperatures. • USE only lined masonry or manufactured Class “A” HT2100 All Fuel Chimney for your furnace. • INSPECT chimney system periodically for structural integrity. • CLEAN the chimney system regularly to prevent creosote accumulation. • NEVER leave the ash pan in your furnace during operation. • DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
Duct Runs
• DO NOT USE DUCT ELBOWS HAVING AN INSIDE RADIUS OF LESS THAN 6 inches (150mm) ON OIL, ELECTRIC, OR GAS FURNACES. • DO NOT CONNECT TO A DOWNFLOW FURNACE. • DO NOT CONNECT DUCTWORK SO THAT A REVERSE FLOW IS POSSIBLE. • OPERATE THE GAS/OIL/ELECTRIC/ FURNACE PERIODICALLY TO ENSURE THAT IT WILL OPERATE SATISFACTORILY WHEN NEEDED. • CERTIFIED FOR INSTALLATION WITH APPROPRIATE DUCTWORK CONFIGURATIONS ONLY. • DO NOT RELOCATE OR BYPASS ANY OF THE SAFETY CONTROLS IN THE ORIGINAL GAS/OIL/ELECTRIC FURNACE INSTALLATION. • DO NOT CONNECT TO ANY GAS FURNACE THAT HAS NOT BEEN CERTIFIED INITIALLY AS COMPLYING WITH CAN/CGA-2.3. • THE OPERATION OF THE GAS FURNACE MUST BE VERIFIED FOR ACCEPTABLE OPERATION BEFORE AND AFTER INSTALLATION OF THE ADD-ON APPLIANCE BY A GAS FITTER WHO IS RECOGNIZED BY THE REGULATORY AUTHORITY. • DO NOT CONNECT TO ANY GAS FURNACE THAT IS NOT EQUIPPED WITH AN AIR-CIRCULATION BLOWER, OR TO A CHIMNEY OR VENT SERVICING A GAS FURNACE OR GAS APPLIANCE. The add-on unit should only be installed on a furnace duct system and chimney that are in good operating condition. If exhaust fans are installed in the storage area they should not create negative pressures in the room where the solid fuel-burning appliance is located. 9
Types of Wood to Use: We advise using only dry, seasoned hardwoods in your Shelter 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, thus allowing more rapid seasoning of the wood. If wood is stored outdoors, it should be completely covered year round to protect it from moisture and exposure to the elements.
FUEL RECOMMENDATIONS: SF 1000 – 20 inch maximum log length
Follow instructions included with the moisture meter that was supplied with this unit to make sure that you are using seasoned wood to achieve the cleanest burn and highest efficiency possible. When using the moisture meter, in addition to following the manufacturer’s instructions, look for readings under 30% moisture content. Also seasoned wood will be noticeably lighter weight than green wood, generally has darker ends with cracks or splits visible. Use extreme caution when opening the door during operation, temperature s are extreme. Wait at least 10 seconds after releasing the latch, and then proceed to the fully open position. Opening the door in this manner is designed to eliminate the possibility of gaseous This wood heater needs periodic inspection and repair for proper operation. If you observe excessive smoke, check to be sure you are burning properly seasoned cordwood and that there are no gaps in the gaskets on the door of the unit. When it becomes necessary to replace the gaskets: • Order part number FCGSKT58 (fuel door) and/or FCGSKT12 (ash door) • Remove old gasket • Install new gasket in gasket channel of door • Cut off excess gasket, ensure that there is no gap where the ends of the gasket material meet 1 0 ignition. Heat resistant gloves are recommended when opening the fuel door, emptying the ash pan. CAUTION: HOT SURFACES. K EEPCHILDRENAWAY. DO NO T TOUCH DURING OPERATION.
CAUTION: • INSPECT FLUE PIPES, JOINTS AND SEALS REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES ARE NOT DRAWING INTO, AND ARE NOT BEING CIRCULATED BY THE AIR-CIRCULATION SYSTEM. • CLEANING OF THE HEAT EXCHANGER, FLUE PIPE, CHIMNEY AND DRAFT INDUCER (IF USED), IS ESPECIALLY IMPORTANT AT THE END OF THE HEATING SEASON TO MINIMIZE CORROSION DURING THE SUMMER MONTHS CAUSED BY THE ACCUMULATED ASH. • Never use chemicals or gasoline to start or maintain your fire. • Do not burn oil, garbage, trash, plastic, or any fuel other than wood in your furnace. Doing so will void the warranty. • DO NOT leave the ash pan inside your furnace during operation. W ARNING: RISK OF FIRE • 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 or ash doors open. WARNING: NEVER fuel your furnace with wet, unseasoned wood or wood that has been exposed to a recent rainfall. Burning wood with high moisture content will cause a rapid accumulation of hazardous creosote, which has been proven to be the most common cause of flue fires. NEVER burn plastics, any wood product containing glue, or wood treated with chemical preservatives in your furnace. The combustion of these substances may release harmful, toxic gases. Do Not Burn: • Garbage; • Lawn clippings or yard waste; • Materials containing rubber, including tires; • Materials containing plastic; • Waste petroleum products, paints or paint thinners, or asphalt products; • Materials containing asbestos; • Construction or demolition debris; • Railroad ties or pressure-treated wood; • Manure or animal remains; • Salt water driftwood or other previously salt water saturated materials; • Unseasoned wood; or • Paper products, cardboard, plywood, or particleboard. The prohibition against burning these materials does not prohibit the use of fire starters made from paper, cardboard, saw dust, wax and similar substances for the purpose of starting a fire in a wood heater. DANGER: RISK OF FIRE OR EXPLOSION – do not burn garbage, gasoline, naphtha, engine oil, or other flammable liquids/inappropriate materials. Supplemental Outside Combustion air may be necessary if: • The solid-fuel-fired appliance does not draw steadily, smells, experiences smoke rollout, burns poorly, or back-drafts whether or not there is combustion present. Opening a window slightly on a calm day may alleviate these symptoms. • The house is equipped with a well-sealed vapor barrier and tight fitting windows, and/or has any powered devices which exhaust house air. • There is excessive condensation on windows in the winter. • A ventilation system is installed in the house.

BURN WOOD ONLY!
First Fire: Set the wall thermostat to 90°F.
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, set the wall thermostat to the desired home 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. Finally adjust the wall thermostat. Ash pan must remain out of furnace during operation. NOTE: Your new Shelter 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 Shelter 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 home and furnace room or area is recommended during the initial firing and break in period to accommodate this possibility. Your new Shelter Furnace is classified as having airtight construction. This type of design should enable you to experience up to 12 hours of burn time 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 Shelter Furnace has been improperly sized for your home. The heat output range, according to B415.1-10 testing, is 25,000 to 75,000 BTUs per hour. Loading Wood: When opening the fuel door during operation, always 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 eliminate 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 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 Shelter Furnace will operate at the highest efficiency by adding fuel in amounts needed to maintain comfortable temperatures in your home. Disposal of Ashes: Heat resistant gloves are recommended. In order to remove ashes from your Shelter Furnace, open the ash door and slide the ash pan to the rear of the furnace. Remove the ash pan 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. The ash pan must be removed from your Shelter Furnace during operation. This precautionary measure is recommended 1 2
because if the ash pan is allowed to remain inside the furnace during operation, it will become dangerously hot to touch, block the flow of air under the grates and reduce the efficiency of the furnace. Remove the ashes from your Shelter 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 Shelter Furnace. CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.
IMPORTANT: FOR TECHNICAL SUPPORT OR CUSTOMER SERVICE ISSUES, DO NOT RETURN TO THE DEALER . THE DEALER DOES NOT HAVE REPLACEMENT PARTS . CALL : 1-800-875-4788.
Draft Blower: The draft blower plays an important role in the operation of your Shelter 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 turns provides more heat in the heat chamber. The heat is then sent through the duct system throughout your home. When the wall thermostat temperature is met, the draft blower shuts
off until the thermostat calls for heat, beginning the cycle again. 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 reduce 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 quantity 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. Chimney Fire Warning: In the event of a chimney fire, take the following actions immediately: • Activate and toss a Chimfex™ Dry Chemical Chimney Fire Extinguisher into the firebox.
• Close the ash door, fuel door and slide cover on the draft motor. • Alert entire household and prepare to evacuate if necessary. • Call your local fire department.
Power Failure: In case of power failure, to prevent your Shelter Furnace from over-heating and causing damage to the electrical components, do NOT add more fuel to the firebox.
There is no warranty on electrical components damaged due to power failure.
1 3
NOTE: OVER-FIRING OR DELIBERATE ABUSE CAN EASILY BE DETERMINED UPON INSPECTION AND WILL VOID THE WARRANTY. Always keep your wood covered year round. Dry wood will produce a higher BTU output and a longer burn time. Refer to the nameplate on furnace for additional information.
WARNING: RISK OF FIRE
• Do not operate with the flue draft exceeding .08 water column inches (19.9 Pa). • Do not operate with fuel loading or ash removal doors open. • Do not store fuel or other combustible material within marked installation clearances. • Inspect and clean flues and chimney regularly.

5.
Problem: Excessive dirt accumulation surrounding air registers in the home.
Possible Causes:
Remedies:
• Furnace is not connected to return air duct and is drawing dirt from furnace room floor and disbursing it throughout home. • Filter box not installed, or no filter in filter box.
• Connect to return air duct system.
• Install filter box on furnace. Install filter in filter box.
6.
Problem: Smoke from the fire chamber is puffing back through the forced draft motor.
Remedies:
Possible Causes:
• Furnace is not connected to
• Connect to return air duct system. Or room may be too airtight, refer to “Location and Installation” section on page 3.
return air and is drawing smoke fumes from the flue.
• Excessively long run of stove pipe from furnace to flue.
• Relocate the furnace so the horizontal run does not exceed 5 feet and has a 2 inch rise per foot. • The run should not contain more than 2 elbows. • Replace with a larger flue providing a minimum of 50 square inches but not more than 100 square inches of draft area. If the flue is within these specifications, check the draft with a draft gage (manometer). Your flue should provide a minimum of .04 water column inches and a maximum of .08 water column inches.
• Too many elbows.
• Insufficient flue size.
7.
Problem: Draft blower runs constantly.
Remedies:
Possible Causes:
• This can be checked by turning the thermostat to a lower setting than the temperature in your home. If the draft blower continues to run, the thermostat may be defective. Replace if necessary. • Replace transformer and relay. • Have a professional determine the proper size furnace and insulation factor of your home.
• Defective wall thermostat.
• Defective relay in transformer.
• Home is not being supplied with a sufficient amount of heat to satisfy the wall thermostat.
8.
Problem: Rapid accumulation of creosote in furnace and flue .
• Use of high resin wood, such as pine. Possible Causes:
Remedies:
• Completely avoid using if at all possible. If hardwoods are not available, fuel the furnace with smaller loads. This will cause the thermostat to call for more heat more often, which will initiate the running of the draft blower. Consequently, the fires will be hotter, thereby reducing the accumulation of creosote. • Install flue gas thermometer and maintain stack temperatures between 300° and 400° F. • See #9. • DANGER: Never use uninsulated stove pipe as chimney. It must not be used on the inside of your home due to high stack temperatures, which create an extreme fire hazard. Uninsulated pipe cannot be used as an outside flue because it causes rapid cooling of the stack gases, which causes them to condense as creosote on the inside of the flue. • Inspect entire flue run, from the exhaust stack of the furnace to the termination cap. Repair as necessary. • Furnace room may be too airtight to supply sufficient amount of oxygen for combustion. Install an aperture to the outside consisting of a minimum of 12 square inches or 4 inches round. • Install stainless steel liner in masonry chimney to reduce creosote formation and improve draw. Use appropriate size stainless liner for the furnace.
• Under-firing the furnace has
caused low flue gas temperature.
• Insufficient chimney draft.
• Using uninsulated stove pipe for the chimney, especially if the construction is on the exterior of the home.
• Improper connection in stove pipe causing air leakage or a structural defect in the chimney itself. • Fire box not receiving adequate amount of oxygen.
• Use of an unlined masonry chimney with a large clay tile opening.

9.
Problem: Down draft on chimney caused by one or more of the following.
Remedies: • This problem may occur in factory built flues because the insulation has settled or a seam has ruptured. In masonry flues, mortar loss may be causing seepage of cooler outside air into the stack. Check entire flue for structural integrity and leakage. Correct or repair as needed, or replace or re-line the chimney. • Remove obstruction.
Possible Causes:
• Flue has a cold spot which
inhibits exhaust discharge from rising properly.
• There is an obstruction outside chimney, such as a tree. • Flue is located too close to the peak of the roof or does not rise above it to provide the proper draft.
• Increase chimney height.
10.
Problem: Odor detected in home during initial firing.
Possible Causes:
Remedies:
• The odor should disappear after a few hours of usage.
• There is an oily film that remains on the steel after the manu- facturing process. Firing the furance has raised the tempera- ture of the fire box to a level that is sufficient to vaporize the residue.
11.
Problem: Excessive smoke discharge from fuel door during reloading.
Remedies: • See #6.
Possible Causes:
• Excessively long stove pipe run from furnace flue. • Too many elbows.
• See #6.
• Insufficient draft.
• See #6.
• Excessive smoke accumulation.
• See #9.

Problem: Home does not achieve comfortable temperature.
Remedies:
• Improper ductwork connection to existing furnace. Possible Causes:
• Refer to information in the manual relating to the proper installation procedures or contact your local heating and cooling contractor. • Refer to information in the manual relating to the proper ducting procedures or consult your local heating and cooling contractor. • Check and replace filter. Proper filter size is 20” by 20” by 1.”
• Improperly sized ducting.
• Excessive dirt accumulation in air filter. • Combustion chamber not receiving an adequate amount of oxygen. • Furnace size is inadequate for your home. • Fueling furnace with wet or unseasoned wood.
• Furnace room may be too airtight. Install an aperature to the outside consisting of a minimum of 12 square inches or 4 inches round.
• Consult a professional to determine correct sizing.
• Completely avoid using if at all possible. If circumstances necessitate the use of wet or unseasoned wood, then fuel the furnace with smaller loads. This will cause the thermostat to call for heat more often, which will initate the running of the draft blower. Consequently, the fires will be hotter, thereby reducing the accumulation of creosote.
13.
Problem: Bugs found in wood.
Possible Causes:
Remedies:
• Inspect the wood for obvious signs of insect infestation such as burrows or holes, avoid using if possible. Do not store wood indoors.
• Wood has rotted or has been laying around for an extended period of time.
