When you receive the Tula,carefully unpack and inspect the stove and allaccompanying parts. Ensure you remove thecorrugated paper padding from the flue collar andbaffle area. Ensure that all parts are included in theaccessory box. If any parts are damaged or missing,please contact your authorized Hearthstone dealerimmediately.PACK LIST1- Tula Model 8190 Woodstove1- Accessory Box containing:1- Fireplace Glove4- Leveling Feet1- Owner’s ManualINSTALLING YOUR STOVEChoose a place to install your Tula woodstove.Inspect this location to make sure that the stove andstovepipes will have the required clearance fromcombustible materials that are near the stove.Combustibles include walls, floor, ceiling, andchimney chase. You must carefully consider theclearances to all of these combustibles beforeactually connecting your stove.If the floor is made of combustible material, then anon-combustible floor protector is required betweenthe floor and the stove. An example of a noncombustiblefloor protector is a hearth constructedwith a continuous layer of tile, brick, slate, glass oranother non-combustible facing. There is no R-valuerequirement.If you use a close clearance connector pipe, ensureit is listed with Underwriter’s Laboratories. Check thelisting of your pipe with UL for the correctclearances.The diagrams in this manual represent typicalinstallations, but are specific to the Simpson Dura-Vent DVL brand.Agency (NFPA) approved wall protection system.Please refer to NFPA Code 211 for specificationsand complete details.

CHIMNEY CONNECTOR SYSTEMS AND CLEARANCESHearthstone Quality Home Heating Products, Inc ® 9Tula Model 8190

OUTSIDE AIR SUPPLY(Optional Kit #91- 53900)You can connect an outside air source directly tothis stove using an optional outside air kit. Theadvantage of providing outside air directly to thestove is that the air used by the stove for combustionis taken from outside the residence rather than fromwithin the room where the stove is located.The outside air kit for this stove allows for the directconnection of the stove's air intake to a minimum 3"(76 mm) diameter duct (supplied by others) whichleads to the outside of the house. When consideringplacement of the duct from the outside of the houseto the hearth, keep in mind the need to avoidstructural members of the house. The outside air kitattaches to the back of the stove. Refer to theinstructions provided with the kit for installation.Figure 4 – Outside Air Kit DetailThe International Residential Code (IRC) does notallow the outside air duct to terminate higher thanthe appliance. Some building officials also do notlike to see any vertical rise in the duct’s termination.Hearthstone recommends the termination be at thesame level, or lower than the air intake on the stove.Locate the termination of the duct on the outsidewall of the home in such a manner to avoid thepossibility of obstruction by snow, leaves or othermaterial. Screen the termination using ¼” x ¼” meshrodent screen and cover it with a rain/wind proofhood (flex pipe, outside termination, mesh, and hoodsupplied by others) Contact your dealer foravailability).VENTING COMPONENTS &CONFIGURATION REQUIREMENTSDO NOT CONNECT THIS UNIT TO A CHIMNEYFLUE USED BY ANOTHER APPLIANCESingle wall connector that is at least 24 MSG or25 MSG blued steel stovepipe.Double wall connector (close clearance pipe)which is used with a listed, factory-built “Type HT"chimney or with a masonry chimney to reduceclearances, is available from severalmanufacturers, your dealer can help you choose.Some air insulated connector pipe modelsavailable are Simpson Dura Vent DVL andMetalbestos DS. Security, GSW and Ameritecalso have acceptable close clearance connectorpipe.When used in a mobile home, a spark arrester isrequired. (See page 14)The chimney connector cannot pass through afloor or ceiling, nor any attic or roof space, closetor similar concealed space. Where ventingrequires passage through a wall or partition ofcombustible construction, the installation mustconform to NFPA Code 211 or CAN/CSA -B365.It is very important to follow minimum clearancesfor chimney connectors to combustibles such aswalls and ceilings when installing the stove.Typical chimney connector clearances areoutlined below. The single wall clearances aregeneric; the double wall clearances shown arespecifically for Simpson DuraVent DVL and mayvary with other brands. Check the specificationsfrom the manufacturer of your connector.COMPONENTS OF A VENTING SYSTEMThe complete venting system consists of severalcomponents: chimney connector, wall thimble, wallpass-through, chimney, and liner. It is necessarythat you install all of these components and maintainthe clearances to combustibles discussed earlier toensure a safe stove installation.To protect against the possibility of a house fire, youmust properly install and constantly maintain theventing system. Upon inspection, immediatelyreplace rusted, cracked, or broken components.The chimney connector is the stovepipe from thewoodstove to the chimney. The chimneyconnector stovepipe is 6" (152 mm) diameter, 24MSG or 25 MSG blued steel connector pipe. Donot use aluminum or galvanized steel pipe - theycannot withstand the extreme temperatures of awood fire.The thimble is a manufactured (or siteconstructed)device installed in combustiblewalls through which the chimney connectorpasses to the chimney. It keeps the walls fromigniting. You must use a wall thimble whenHearthstone Quality Home Heating Products, Inc ® 10Tula Model 8190

installing a chimney connector through acombustible wall to the chimney.A wall pass-through (or chimney supportpackage) also keeps the walls from igniting. Youmust use one when connecting through a wall orceiling to a prefabricated chimney.Only install this stove to a lined masonrychimney or an approved high temperatureprefabricated residential type building heatingappliance chimney. Do not connect this stove toa chimney serving another appliance; you willcompromise the safe operation of both the woodstove and the connected appliance.A liner is the UL 1777 or ULC S635 (for factorybuilt fireplace or masonry) chimney.You must connect your stove to a chimneycomparable to those recommended in this manual.Do not use stovepipe as a chimney. Use stovepipefor freestanding installations only to connect thestove to a proper chimney.WARNING: DO NOT CONNECT THIS APPLIANCETO ANY AIR DISTRIBUTION DUCT OR SYSTEM.INSTALLING A VENTING SYSTEMAttach stovepipe sections to the flue collar and toeach other with the crimped end toward the stove. Ifcreosote builds up, this allows the creosote to runinto the stove and not on the outside of thestovepipe or onto the stove.Secure all joints, including attaching the stovepipe tothe stove's flue collar, with three sheet metal screws.Install #10 x 1/2" (3 mm x 13 mm) sheet metalscrews into the holes pre-drilled in the flue collar.Disregarding the screws can cause joints toseparate from the vibrations that result from acreosote chimney fire.You can simplify connecting stovepipe by usingadditional accessories such as telescoping pipes,slip-connectors or clean-out tees. These accessoriesease the periodic inspection of your chimney, as wellas allow you to dismantle the stovepipe easily(without moving the stove).Install the stove as close as practical to the chimney,while maintaining all proper clearances. Installstovepipe that is as short and as straight aspossible. Horizontal runs of stovepipe must alwaysrise away from the stove at a minimum of 1/4" perfoot (21mm/m).We do not recommend long runs of stovepipe toincrease heat dispersal. Longer lengths ofstovepipe, or more connecting elbows, thannecessary increase the chances of draft resistanceand the accumulation of creosote buildup.In general, you do not need to install a stovepipedamper with the Tula. Some installations, however,could benefit from a stovepipe damper, such as atall chimney which can create a higher than normaldraft. In such cases, a damper can help regulate thedraft. The Tula requires a draft between 0.06" and0.1" WC. For drafts above 0.1" WC, install astovepipe damper. Check the draft at stoveinstallation time.Remember, the NFPA recommends minimumclearances for chimney connectors to combustiblessuch as walls and ceilings. Once the stove isinstalled at safe distances from these combustiblesurfaces, it is also important to maintain theseconnector clearances for the remainder of theinstallation.CONNECTING THE STOVE TO A CHIMNEYYou can install your Tula to a prefabricated metalchimney, or to a masonry chimney.This room heater must be connected to (1) a listedType HT (2100° F) chimney per UL 103 or ULCS629, or (2) a code-approved masonry chimney witha flue liner. The chimney size should not be lessthan the flue collar, or more than three times greaterthan the cross-sectional area of the flue collar.We recommend installing a cleanout tee wherepossible to simplify chimney cleaning andmaintenance.Connecting to a Prefabricated Metal ChimneyThere are two ways to install a prefabricated metalchimney:An interior installation where the chimneypasses inside the residence through the ceilingand roof.An exterior installation where the chimneypasses through the wall behind the stove thenup the outside of the residence.Whenever possible, choose an interior chimney. Aninterior chimney heats up quickly and retains itsheat; thus promotes a better draft and discouragesthe formation of creosote. An exterior chimney doesnot benefit from the warmth of the building, so ittypically operates at lower flue temperatures than aninterior chimney and may experience increasedcreosote accumulation.Hearthstone Quality Home Heating Products, Inc ® 11Tula Model 8190

When connecting the Tula to a prefabricated metalchimney, you must follow, precisely, themanufacturer's installation instructions. Use onlyType HT (2100° F), prefabricated metal chimneyslisted per UL 103 or ULC S629 standards.Ensure the size of the prefabricated chimney’s flueis appropriate for the Tula. The Tula requires a 6"(152 mm) inside diameter flue for new installations.A 6” diameter flue provides adequate draft andperformance. You can use an 8" (203 mm) diameterexisting flue with a reducer. An oversized fluecontributes to creosote accumulation. (In this case,bigger is NOT better.)When purchasing a prefabricated chimney to installwith your stove, Ensure you also purchase from thesame manufacturer the wall pass-through (or ceilingsupport package), "T" section package, fire-stops(when needed), insulation shield, roof flashing,chimney cap, and any other required accessories.Follow the manufacturer’s instructions wheninstalling the chimney and accessories. In addition,ensure you maintain all manufacturers’recommendations for the proper clearances to thechimney.Connection to a Masonry ChimneyConsider two primary elements when connectingyour stove to a masonry chimney: the chimney itselfand the thimble where the stovepipe connects to thechimney. Use only code approved masonrychimneys containing a proper flue liner.Before connecting to a masonry chimney, hire aprofessional to examine the chimney for cracks,loose mortar, and other signs of deterioration andblockage. If the chimney needs repair, completethem before installing and using your stove. Do notinstall your stove until the chimney is safe for use.Ensure the chimney’s cleanout is complete andworking properly. To avoid a loss of draft, thecleanout door must close completely and provide atight seal. If the cleanout door leaks, the chimney willcool, your stove will perform poorly, and creosotecan form.Ensure the size of the chimney’s flue is appropriatefor this stove and that it is not too large. Use amasonry chimney with a maximum 6” Diameter or 8"x 8" (203 mm x 203 mm) tile size for best results. Anoversized flue contributes to the accumulation ofcreosote.Use the following checklist to ensure that yourmasonry chimney meets these minimumrequirements:Masonry Chimney wall construction:Mortared brick or modular block at least 4" (102mm) thick – must use linerA mortared rubble or stone wall – must use linerFlue liner options:Tile - minimum wall thickness of 5/8" (16 mm),installed with refractory mortar, and with at least1" (25 mm) air space around the linerStainless steel - UL listed 6” diameter, insulatedor wrapped liner, or the space around the linerfilled with vermiculite or suitable material (thesekeep the liner warmer for better performance)Ensure any equivalent flue liner is a listedchimney liner system meeting type HTrequirements or other approved material.Interior chimney requirements:Must have at least 2" (51 mm) clearance tocombustible materialsMust install fire stops at the spaces where thechimney passes through floors and/or ceilingAny insulation material must be at least 2" (51mm) from the chimneyExterior chimney requirements:At least 1" (25 mm) clearance to combustiblematerialsChimney height requirements (See Figure 6):At least 3 feet (0.9 m) higher than the highestpart of the roof opening through which it passes.At least 2 feet (0.6 m) higher than any part of theroof within 10 feet (3 m) measured horizontallyfrom the top of the chimney.The recommended minimum chimney height is 10feet (3 m) off the floor. The recommended maximumchimney height is 30 feet (9m).The Tula requires adraft between 0.06” and 0.1” water column. Ensureyour chimney is long enough to provide theminimum draft, and use a damper if your installationhas a required chimney height that provides toomuch draft.Hearthstone Quality Home Heating Products, Inc ® 12Tula Model 8190

Use Hearthstone’s Kit #91-99900 -Mobile Home Lock Down Kit. Installationinstructions are included with the kit.Figure 7 - Lock Down Kit DetailInstall a Mobile Home Chimney & ConnectorKit*.Each kit must include:Stainless spark arrester cap, storm collar,Adjustable vented flashing – 0/12 – 6/12,Two 24” chimney pipes, 24” support boxwith built-in starter section and trim.* (any UL or ULC approved equipment is acceptable)WARNING: DO NOT INSTALL IN A SLEEPINGROOM IN A MOBILE HOME.CAUTION: MAINTAIN THE STRUCTURALINTEGRITY OF THE MOBILE HOME WALLS,Figure 8CAUTION: REMOVE THE CHIMNEY WHENTRANSPORTING THE MOBILE HOME!Hearthstone Quality Home Heating Products, Inc ® 15Tula Model 8190

Once your Tula is installed, you are ready to light afire.Every installation, season’s firewood, and operator’stechnique varies. Learn how to use you stove mostefficiently for your installation. We can give you thebasic principles, but only you can ensure maximizingthe potential of your stove while also operating itsafely.WARNING: HOT WHILE IN OPERATION! KEEPCHILDREN, CLOTHING AND FURNITURE AWAY.CONTACT MAY CAUSE SKIN BURNS.Read this entire chapter before lighting your first fire.It explains the controls and features of your woodstove, how to choose firewood, and how to use yourstove on a daily basis.CONTROLS AND FEATURESBefore lighting any fires, become familiar with thelocation and operation of your stove's controls andfeatures and learn how to use them (See Figure 9).For your own safety, do not modify these features inany way. We recommend you use the providedfireplace glove when the stove is in operation andhot.OperationASH PAN: (This becomes hot during operation. It isbest to remove the ash pan only after the stovecools). To access the ash pan you must open thefirebox door. Open the firebox door and locate theash pan handle. To remove the ash pan, grip thehandle, and then pull it out. The lid for the ash pan isstored under the ash pan. Use the lid to contain theashes during transport for disposal. The ash pancollects the ash residue from each fire and when full,allows you to remove the ash conveniently from thestove. Clear the firebox of ashes periodically. Sift theashes through the grate in the bottom of the fireboxinto the ash pan.To replace the ash pan, place the pan lid back intothe bottom of the ash pan receptacle and slide theash pan back into place on top of the lid. Do notoperate the stove unless the ASH PAN is inplace, and properly sealed by the gasket on thefirebox door. A poor seal could causeoverheating and damage the stove.PRIMARY AIR CONTROL: The primary air controlrod (1) is located on the lower right side of the stove.The primary air control allows you to regulate theamount of air entering the firebox. Generally, themore air allowed into the firebox, the faster the rateof burn; conversely, less air creates a slower burn.For maximum air flow, pull the primary air rod as farout as possible; push the primary air control rod inas far as possible for minimum air flow (does notclose completely).Figure 9 - Controls & FeaturesFRONT DOOR HANDLE: The firebox door allowsyou to load wood into your stove; a fixed handleoperates the door. To open the door, pull out and upon the handle and swing the door away from thestove. To latch the door, push the door tightlytowards the firebox then continue to push the handlein and down until it latches shut. Gently pull on thedoor handle to make sure it is properly latched.Figure 10 – Air Control OperationHearthstone Quality Home Heating Products, Inc ® 16Tula Model 8190

CHOOSING FIREWOODBurn only natural firewood (known as cordwood) inthe Tula 8190 Wood Heater. This stove is notdesigned to burn other fuels.CAUTION: DO NOT USE CHEMICALS ORFLAMMABLE FLUIDS TO START THE FIRE. DONOT USE CHARCOAL, PELLETS, COAL,ARTIFICIAL LOGS OR ANY OTHER MATERIALSAS FUEL; THEY ARE NOT SAFE. DO NOT BURNGARBAGE OR FLAMMABLE FLUIDS.The quality of your firewood directly affects heatoutput, duration of burn and performance of yourstove. Softwoods generally burn hotter and faster,while hardwoods burn longer and produce bettercoals. Density and moisture content are two criticalfactors to consider when purchasing wood for yourstove.The following is a list of some wood species andtheir relative BTU (British Thermal Unit) content. Thehigher the BTU content, the longer the burn.Firewood with higher BTUs is generally ideal for awood stove.Wood Heat Value: Sorted By BtuContentCommon Name Lb/ cord MBTU/cordHighOsage Orange (Hedge) 4,728 32.9Hickory, Shagbark 4,327 27.7Hop Hornbeam (Ironwood) 4,267 27.3Beech, Blue (Ironwood) 3,890 26.8Birch, Black 3,890 26.8Locust, Black 3,890 26.8Hickory, Bitternut 3,832 26.7Locust, Honey 3,832 26.7Apple 4,100 26.5Mulberry 3,712 25.8Oak, White 4,012 25.7Medium HighBeech, European 3,757 24Maple, Sugar 3,757 24Oak, Red 3,757 24Ash, White 3,689 23.6Birch, Yellow 3,689 23.6MediumJuniper, Rocky Mtn 3,150 21.8Elm, Red 3,112 21.6Coffeetree, Kentucky 3.112 21.6Hackberry 3,247 20.8Tamarack 3,247 20.8Birch, Gray 3,179 20.3Birch, White (Paper) 3,179 20.3Walnut, Black 3,192 20.2Cherry 3,120 20Ash, Green 2,880 19.9Cherry, Black 2,880 19.9Elm, American 3,052 19.5Elm, White 3,052 19.5Sycamore 2,808 19.5Ash, Black 2,992 19.1Maple, Red 2,924 18.7Fir, Douglas 2,900 18.1Medium LowBoxelder 2,797 17.9Alder, Red 2,710 17.2Pine, Jack 2,669 17.1Pine, Norway (Red Pine) 2,669 17.1Pine, Pitch 2,669 17.1Catalpa 2,360 16.4Hemlock 2,482 15.9Spruce, Black 2,482 15.9Pine, Ponderosa 2,380 15.2LowAspen, American 2,290 14.7Butternut (Walnut, White) 2,100 14.5Spruce 2,100 14.5Willow 2,100 14.5Fir, Balsam 2,236 14.3Pine, White (Eastern,2,236 14.3Western)Fir, Concolor (White) 2,104 14.1Basswood (Linden) 2,108 13.8Buckeye, Ohio 1,984 13.8Cottonwood 2,108 13.5Cedar, White 1,913 12.2Moisture content also plays a key role in theperformance of your stove. Wood freshly cut from aliving tree (green wood) contains a great deal ofHearthstone Quality Home Heating Products, Inc ® 17Tula Model 8190

moisture. As you might expect, green wood burnspoorly. You must season green wood before using itin your wood stove. To season green wood properly,split, stack, and allow it to air dry for a period of oneyear. Green wood may provide less than 2000 Btuper pound, whereas dry wood can provide up to7000 Btu per pound.Stack the firewood on skids or blocks to keep it offthe ground, cover only the top of the stack. Plastic ortarps that cover the sides of the woodpile trapmoisture and prevent the wood from drying. As forstacking, an old Vermonter said, "The spacesbetween the logs should be large enough for amouse to get through, but not for the cat that'schasing it."CAUTION: DO NOT STORE FIREWOOD WITHINTHE STOVE'S SPECIFIED CLEARANCES TOCOMBUSTIBLE MATERIALS.BUILDING A FIREOnce you understand the controls of your woodstove and have the appropriate firewood, you areready to start a fire.WARNING: NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOALLIGHTER FLUID, OR SIMILAR LIQUIDS TO STARTOR 'FRESHEN UP' A FIRE IN THIS HEATER.KEEP ALL SUCH LIQUIDS WELL AWAY FROMTHE HEATER WHILE IT IS IN USE.When you light your first fires, the woodstove willemit some smoke and fumes. This is normal “offgassing”of the paints and oils used whenmanufacturing the woodstove. If you find itnecessary, open a few windows to vent your room.The smoke and fumes will usually subside after 10to 20 minutes of operation. The odor and smoke willend once the stove is “cured”.The first few fires of the season may produce otherodors from impurities that exist in the areaimmediately surrounding the stove. Some potentialimpurities are cleaning solvents, paint solvents,cigarette smoke, and soot from scented candles, pethair, dust, adhesives, a new carpet, and newtextiles. These odors will dissipate over time. Youcan alleviate these odors by opening a few windowsor otherwise creating additional ventilation aroundyour stove. If any odor persists, contact your dealeror an authorized service technician.If you adhere to the operating procedures in thismanual, the steel, cast iron, and refractorycomponents of your stove will give you many yearsof trouble-free use. With use, the color of therefractory panels will change and small fracturesmay appear on the surface. These changes do notaffect the function of the stove. If a panel breakscompletely, it must be replacedAvoid the following conditions that can cause theglass, refractory panels, steel or cast iron pieces tobreak:Do not throw wood into the stove.Do not use the door as a lever to force wood intothe stove.Do not load wood encrusted with ice into aburning stove - the thermal shock can causedamage.Do not use a manufactured log grate. Burn thefire directly on the cast iron bottom of thefirebox.NORMAL OPERATIONPrior to loading the stove, ensure the ash grate andthe ash pan are in place.BUILDING A FIRE FOR EVERYDAY USE1) Open the front door and place five or sixdouble sheets of tightly twisted newspaperin the center of the firebox. Arrange kindlingin a tee-pee configuration over thenewspaper. Use approximately 10 pieces ofkindling, 1/2" (13 mm) in diameter and 10" to16" (254 mm to 406 mm) long.2) Fully open the primary air control by pullingit completely out, away from the firebox.3) Light the paper under the kindling. Leave thefront door slightly ajar momentarily until thekindling begins to burn and draft begins topull.4) Close the door and allow the fire to burn.5) Once the kindling is burning, open the frontdoor and add logs, small at first, to build thefire up. Ensure you keep the logs away fromthe glass in front in order for the air-washsystem to work properly. Keep the front doorand ash pan closed while the stove is in use.6) Once the fire is burning well, use the primaryair control to regulate the desired rate ofburn. Pull the handle out to open the primaryair control for a high rate of burn; or push itin for a low rate of burn. The air control doesnot close completely.Note: When opening the front door to reload or rearrangelogs, it is advisable to open the door just acrack, pause for a moment then open the doorHearthstone Quality Home Heating Products, Inc ® 18Tula Model 8190

completely. This procedure allows the firebox toclear of smoke before the door is open fully. Inaddition, reloading on a bed of hot, red coalsreduces smoking time and brings fresh fuel up to ahigh temperature rapidly.BURN RATEHIGH BURN: Fully load the firebox with wood on abed of hot coals or on an actively flaming fire andfully open the primary air control by pulling it all theway out, away from the firebox. A high burn rateonce or twice a day for 35 to 45 minutes to heat thestovepipe and chimney fully, will help minimizecreosote accumulation.Figure 11 – High Burn SettingMEDIUM HIGH BURN: With the primary air controlin the open position, push the control rod in one toone and a half ‘notches’ towards the firebox, orabout one quarter to one third of the way in.Figure 12 – Medium Burn SettingMEDIUM LOW BURN: With the primary air controlin the open position, push the handle inward abouttwo to two and a half notches, or about half to twothirds of the way in. A medium-low burn rate is thetypical setting and is preferable if the stove isunattended.LOW BURN: Push the primary air control inward allthe way to the firebox (see figure 10). This closesthe air shutter to its minimum opening. A low burnrate over extended periods is not advisable as it canpromote the accumulation of creosote. Inspect theventing system frequently if using low burn ratesconsistently.OVER-FIRE CAUTIONOver-firing means the stove is operating attemperatures above normal temperatures reachedduring High Burns outlined in the BURN RATEsection. Carefully avoid over-firing, as it will damagethe stove. Symptoms of chronic over-firing caninclude warped components, short burn times, aroaring sound in the stove or stovepipe, anddiscoloration of the stovepipe. A properly installedstove using fuel and following operating proceduresas outlined in this manual should not over-fire.Excessive draft, inappropriate fuel, and operatorerror can cause over-firing. Correct an over-firesituation as follows:EXCESSIVE DRAFT: Contact your local dealerto have a draft reading taken. Any draft inexcess of 0.1 WC requires a damper in thestovepipe. Some installations may require morethan one damper.INAPPROPRIATE FUEL: Do not burn coal; kilndried lumber, wax logs or anything other thannatural cordwood.OPERATOR ERROR: Ensure all the gasketsare in good condition. Replace worn out orcompressed gaskets. Do not burn the stove withthe front door in the open, or partially openposition.If you suspect that your stove is over-firing,discontinue use and contact your dealerimmediately. Damage caused by over-firing is notcovered by your warranty. Results of over-firingcan include warped or burned out internal parts,cracked vermiculite panels, discolored or warpedexternal parts, and damaged finish.ANY SIGNS OF OVER-FIRING WILL VOID YOURWARRANTY!Hearthstone Quality Home Heating Products, Inc ® 19Tula Model 8190

REMOVAL AND DISPOSAL OF ASHESRemove ashes only when the stove is cold. Use theprovided protective fireplace glove if the ash pan iswarm. Exercise extreme caution when handling,storing or disposing of ashes.The ash pan is located behind the firebox door at thebottom of the stove. The ash pan collects burnedash from a fire and allows you to remove the ashconveniently from your wood stove. Clear the fireboxof ashes, and do not let them build up too high. Youcan leave a thin layer of ashes in the firebox ifpreferred. It is important to prevent ashes frombuilding up around the front door opening or they willspill out, or they can pack into the gasket channeland prevent proper sealing. To remove ashes, siftthe ashes across the grate into the ash pan. The ashpan is easy to remove and has a handle and lid forconvenient disposal of ashes. The lid should bestored under the ash pan when burning the stove.Dump ashes from the ash pan directly into a metalcontainer with a tight fitting lid. Do not place anyother items or trash into the metal container. Do notpour water into the container. Replace thecontainer’s lid and allow the ashes to cool. Neverplace the ash disposal container on a combustiblesurface or vinyl flooring, as the container could behot!Pending disposal, place the closed ash container ona noncombustible floor or on the ground, well awayfrom all combustible materials, liquid fuels, orvehicles. Retain ashes in the closed container untilall coals thoroughly cool.If the ashes are disposed of by burial in soil orotherwise locally dispersed, they should be retainedin the closed container until all cinders havethoroughly cooled.NEVER place ashes in wooden or plasticcontainers, in trashcans with other trash, or inpaper or plastic bags, no matter how long thefire has been out. Coals within a bed of ashescan remain hot for several days once removedfrom the firebox.Hearthstone Quality Home Heating Products, Inc ® 20Tula Model 8190

NOTE: ANY SYMPTOMS OF OVER-FIRING WILLVOID YOUR WARRANTY!CREOSOTE FORMATION & REMOVALWhen wood burns slowly at low temperatures, it mayproduce tar and other organic vapors, whichcombine with expelled moisture to form creosote.These creosote vapors condense in the relativelycool chimney flue of a slow-burning fire. As a result,creosote residue accumulates on the flue lining.When ignited, this creosote makes an extremely hotfire, which may damage the chimney or even destroythe house. When burning wood, inspect the chimneyconnector and chimney at least once every twomonths during the heating season to determine ifthere is a creosote buildup.If a creosote build-up occurs, inspect the stovepipeconnector and chimney more often, at least monthlyduring the heating season to monitor theaccumulation. If a creosote residue greater that 1/4"(6 mm) accumulates, remove it to reduce the risk ofa chimney fire.PreventionBurn the stove with the primary air control fully openfor 35 - 45 minutes daily to burn out creosotedeposits from within the stove and the ventingsystem.After reloading with wood, burn the stove with theprimary air control fully open for 15 to 20 minutes.This manner of operation ensures early engagementof the secondary combustion system that minimizescreosote buildup in the chimney.If your glass always remains dirty, your operatingtemperatures are too low or your wood is wet;therefore, there is a higher risk of creosote buildup.Inspect the venting system at the stove connectionand at the chimney top. Cooler surfaces tend tobuild creosote deposits faster, so it is important tocheck the chimney at the top (where it is coolest) aswell as from the bottom near the stove.CleaningRemove accumulated creosote with a cleaningbrush specifically designed for the type of chimneyin use. We recommend you use a certified chimneysweep to perform this service. Contact your dealerfor the name of a certified chimney sweep in yourarea (your dealer may be a certified sweep!).MaintenanceWe recommend that before each heating seasonyou have the entire system professionally inspected,cleaned and repaired, if necessary.GASKETSReplace door gasket material every two to threeseasons, or whenever it becomes deteriorated orloose, and depending on stove use. If the door sealleaks, a new gasket will ensure a tight seal andimprove stove performance.We recommend you only use Hearthstonereplacement gaskets when you need to replace yourdoor gasket. Contact your dealer for a gasket kit thatincludes instructions, and the gasket for your stove.Required Door Gasket: PN: 3110-072, 2700 mm(106.3") Length.DOOR GASKET REPLACEMENTPROCEDURES:1. Note the routing of the old gasket beforeremoval.2. To replace the door gasket, pull the old ropegasket out of its channel. Clean all gasketchannels with a small wire brush ifnecessary.3. Vacuum the inside of the door as required.4. Route the new gasket exactly like the oldone. Or, start the gasket at one thechannel’s T intersections to the left or rightbelow the glass.5. Using no glue, or cement, work your way upor down and push the new gasket uniformlyinto the channel without stretching orcompressing the gasket material.6. Pinch the gasket into place as necessary.No glue is necessary.7. When you reach the channel’s other Tintersection, turn 90° horizontally using thechannel just below the glass. The trailingend of the gasket should end at the oppositeT intersection from where you started.8. Ensure there are no gaps where the ends ofthe gasket meet itself.9. Check the gasket seal using the paper test –close the door on a long narrow strip ofprinter paper or newspaper, if it pulls outwithout resistance, the seal is not good.Alternatively, aim a powerful flashlight intothe space around the door from the outside(then look in through the glass at the areaHearthstone Quality Home Heating Products, Inc ® 21Tula Model 8190

opposite the light – if you see light, the sealis not good and will leak). The leak will mostlikely be where the gasket was not fullyinserted into the channel, or where stretched(thinner), or adjacent to an area where thegasket was compressed (thicker).10. First, adjust the gasket as necessary byreseating it uniformly. If that does not work,adjust the latch mechanism (see below) so itapplies more pressure when the door isclosed.LATCH ADJUSTMENT PROCEDURES:1. Test gasket seal quality with small latchadjustments first. The curved door geometrymeans a little movement goes a long way.Too much pressure makes the door difficultto open and close.2. Loosen mounting bolts with a 10mm wrenchto shift catch assembly to apply more, orless closing pressure to the gasket.3. If the catch bushing is worn, or seized –contact your Hearthstone dealer for areplacement.Figure 13 Latch Catch DetailCaution: Do not drop catch into opening!Mounting BoltsCatchBushingGLASSThe glass used in our stoves is actually not plainglass, but a tough, clear ceramic material capable ofoperating at temperatures up to 2300° F. Do notoperate the stove with a broken door glass. Do notabuse the front door by striking or slamming.When necessary, clean the glass. We recommendusing a damp paper towel dipped in gray ash. Rubthe inside of the glass with a circular motion. Whenall the deposits are removed, clean up with windowcleaner or with commercial stove glass cleaners,which are available from your local dealer. Neverattempt to clean the glass while the fire is burning orwhile the glass is hot. Remove deposits by followingthe instructions provided with the cleaner. Wipe thecleaner off with a soft cloth, or black & whitenewsprint.Important: scratching or etching the glasswill weaken the integrity of the glass. Do notuse a razor blade, steel wool, or any otherabrasive material to clean the glass. Use acleaner specifically manufactured forwoodstoves only.The front door glass is a ceramic, shock-resistantglass, made specifically for use in woodstoves. Donot use any replacement glass other than theceramic glass manufactured and supplied for use inthis woodstove. Replacement glass is availablethrough your local dealer.Replace the door glass immediately if broken orchipped. Contact your local dealer for replacementglass. The glass kit includes instructions andeverything needed for the repair. If you replace theglass yourself, wear work gloves and safety glasses.Required Glass Kit: PN: 91-58900 (Glass withgasket applied).GLASS REPLACEMENT PROCEDURES:Follow the instructions included with thereplacement glass kit or:1. Remove the screws from the glass retainer (usepenetrating oil if necessary). Remove theretainer with the damaged glass from the door.2. Carefully separate the glass retainer from thedamaged glass and set it aside for reinstallation.3. Discard the damaged glass.4. Remove any remaining glass and old gasketmaterial.5. Clean the screw holes and place a small amountof anti-seize compound in each one.Hearthstone Quality Home Heating Products, Inc ® 22Tula Model 8190

6. Place the retainer on the gasketed new glassand place the assembly onto the door.7. Screw the glass retainer back on the door usinga crisscross pattern. Tighten the screws no morethan 1/8 th of a turn after they seat. (The glasswill break at this point if not positioned correctly).8.

TroubleshootingCOMMON ISSUESVirtually all woodstove operators experience basiccommon problems at one time or another. Most arecorrectable and generally require only a minoradjustment of the stove, installation, or operatingtechnique. In cases where weather conditionsdramatically affect stove performance, the problemsare typically temporary and solve themselves oncethe weather changes.If you question whether your stove is producingadequate heat, the best way to troubleshoot theproblem is to monitor the temperature of the stackno more than 12 inches (30 cm) above the fluecollar. A 400° F (200° C) stovepipe confirms thestove is supplying sufficient heat. Keep in mind thatyour house itself will regulate room/housetemperatures. How well the walls, floors and ceilingsare insulated, the number and size of windows, thetightness of outside doors, and the construction orstyle of your house (vaulted ceilings or other openspaces which collect large percentages of heat,ceiling fans, etc.) all are determining factors of roomtemperature.Your stove's performance is also dependant on itsinstallation. One common cause of poorperformance is an oversized chimney flue.Oversized chimney flues result in decreased draft,which prevents the smoke from rising out thechimney. Oversized flues are also more difficult toheat effectively, especially when burning a highefficiency stove. Cool flue temperatures inhibit theestablishment of a strong draft (and encourage theaccumulation of creosote). The lack of a strong draftwill cause the fire to die down and may even forcesmoke to pour into the room.If your chimney is the proper size and a strong draftis not easily established, there is the possibility thatthe chimney is too cold. Again, hot chimneyspromote stronger drafts. Opening a window briefly inthe room while lighting the stove may help.Other draft guidelines are as follows:An "AIRTIGHT" HOUSE: The air supply (infiltration)to the interior of the house may be inadequate ifyour home is super-insulated or especially wellsealed. This phenomenon of air starvation within thebuilding is exacerbated if exhaust fans, such asclothes dryers, bathroom fans or cook stove exhaustfans, are in operation within the home. Outfittingyour stove with the optional outside air adaptorconnected to an air duct, which leads to the outsideof the building, can correct this problem.Tall Trees or Buildings: These obstructions, whenlocated close to the top of the chimney can causechronic or occasional downdrafts. When selecting asite for a new chimney, consider the placement ofother objects near the proposed chimney location.Wind Velocity: Generally, the stronger and steadiera wind, the stronger (better) the draft. However,"gusty" wind conditions can cause erraticdowndrafts. For consistent problems, consider ahigh wind cap, such as the Vacu-Stack.Barometric Pressure: Chimney drafts are typicallysluggish on balmy, wet or muggy days (lowbarometric pressure). This is a weather-relatedphenomenon, which generally is self-correcting asthe weather changes.Briskness of Fire: The hotter the fire in your stove,the hotter your chimney and, therefore, the strongerthe draft.Breaks in the Venting System: An unsealedclean-out door at the bottom of the chimney, leakystovepipe joints, a poor stovepipe-to-thimbleconnection, missing caps, or a leaky chimney all cancause inadequate draft.Seasonal Factors: Early fall and late spring aregenerally difficult seasons in which to establishproper drafts. The colder the outside air is relative toroom temperature, the stronger the draft.OPERATING THE STOVEAs outlined above, there are days when a good draftis just not easy to establish. The causes are usuallyseasonal factors or a cold chimney. Try starting thefire by using small kindling and fuel to obtain a quick,hot fire. Tend the fire frequently with small fuel untilthe chimney is hot and the draft is well established.Sometimes, partially opening a first floor windowbriefly will help quickly get draft established.Hearthstone Quality Home Heating Products, Inc ® 27Tula Model 8190
