USING THIS MANUAL

Please read and carefully follow all of the instructions found in this manual. Please pay special attention to the safety instructions provided in this manual.

PRODUCT IS SUBJECT TO CHANGE WITHOUT NOTICE

IMPORTANT SAFETY AND WARNIING INFORMATION

READ THIS MANUAL IN ITS ENTIRETY AND UNDERSTAND THESE RULES TO FOLLOW FOR SAFETY.

1. When this room heater is not properly installed, a house ﬁre may result. To reduce the risk of ﬁre, follow the installation instructions. Contact local building or ﬁre ofﬁcials about restrictions and installation inspection requirements in your area.

2. Wear gloves during installation to avoid injury from sharp edges on the stove and/or its parts.

3. This unit is designed and engineered to burn only dry, wellseasoned wood. Burning wet wood will greatly reduce your stoves efﬁciency, produce excessive amounts of smoke and can cause dangerous chimney ﬁres due to creosote build-up.

4. Before opening the door, the draft control must be fully open to avoid possible combustion ﬂash (ignition of hot volatile gases as the door is opened).

5. Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter ﬂuid, or similar liquids to start or ’freshenup’ a ﬁre in this heater. Keep all such liquids well away from the heater while it is in use. DO NOT USE CHEMICALS OR FLUIDS

TO START THE FIRE.

6. While burning, fuel utilizes oxygen from the air in the room. Be sure to allow an adequate amount of fresh air into the room where the stove is burning.

7. The outside surface of the stove will be hot while burning properly and can set items like clothing and curtains on ﬁre. Keep furnishings and other combustible materials away from the stove. Using the heat from the stove to dry wet clothing can be hazardous if clothes are placed too near the surface of the stove.

8. HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING

FURNISHINGS AND COMBUSTIBLE MATERIAL A CONSIDERABLE DISTANCE AWAY. CONTACT MAY CAUSE SKIN BURNS.

Do not allow children to play near the stove without close supervision. Do not touch the stove while it is burning. Use extreme caution while the unit is in use. Surface temperatures become dangerously hot and can cause serious burns.

9. Do not allow anyone to operate the stove who is not familiar with the operating instructions.

10. Attempts to achieve heat output rates that exceed stove design speciﬁcations can result in permanent damage to the stove. Never leave your stove unattended on high burn rates. This may cause overﬁring. Overﬁring the stove may cause a house ﬁre. If the stove glows, you are overﬁring.

11. Keep a water hose or hand-operated ﬁre extinguisher close for safety.

12. Smoke Detectors - Since there are always several potential sources of ﬁre in any home, we recommend installing smoke detectors. If possible, install the smoke detector in a hallway adjacent to the room (to reduce the possibility of occasional false activation from the heat produced by the stove). If your local code requires a smoke detector be installed within the same room, you must follow the requirements of your local code. Check with your local building department for requirements in your area.

13. Inspect your chimney at least once a month during the burning season to check for soot and creosote accumulations. Any accumulations over 1/8” thick should be removed by a professional chimney sweep. Do not attempt to burn out heavy creosote accumulations with a hot ﬁre. If large accumulations are occurring, review your burning procedures.

14. If a creosote ﬁre should develop, the ﬁre department should be called immediately and then attempts should be made to control the ﬁre until assistance arrives. If a “runaway” ﬁre should develop causing over-heating of the stove, the door and draft regulators should be closed immediately. The ﬁre should die down once deprived of oxygen. After a severe chimney ﬁre, the complete chimney system should be checked before further use.

15. Do Not Use Grate Or Elevate Fire - Build Wood Fire Directly On Hearth (ﬁrebrick). Do not use andirons or other methods of supporting the fuel.

16. Please read this entire manual before you install and use your new room heater. Failure to follow instructions may result in property damage, bodily injury, or even death.

17. Check all local building and safety codes before installation. The installation instructions and appropriate code requirements must be followed exactly and without compromise. In the absence of local codes the following standards and codes must be followed.

18. In the U.S.A, install in accordance with the National Fire Protection Association’s Code, NFPA 211, Standards for Chimneys, Fireplaces, Vents and Solid-Fuel-Burning Appliances, or similar regulations, may apply to the installation of a Solid-Fuel-Burning appliance in your area. In Canada, the guideline is established by the CSA Standard, CAN/CSA-B365M93, Installation Code for Solid-Fuel-Burning Appliances and Equipment.

19. DO NOT CONNECT TO OR USE IN CONJUNCTION WITH ANY

AIR DISTRIBUTION DUCTWORK UNLESS SPECIFICALLY APPROVED FOR SUCH INSTALLATIONS.

20. WARNING: BURNING IMPROPER FUEL (I.E. CHARCOAL) CAN RESULT IN CARBON MONOXIDE POISONING, WHICH MAY LEAD TO DEATH!

21. Carbon Monoxide Poisoning – Early signs of carbon monox- ide poisoning resemble the ﬂu with headaches, dizziness, or nausea. If you have these signs, get fresh air at once! Have the heater inspected by a qualiﬁed service technician. Some people are more affected by carbon monoxide than others. These include pregnant women, people with heart or lung disease or anemia, those under the inﬂuence of alcohol, and those at high altitudes.

22. Failure to use manufacturer provided parts, variations in techniques and construction materials or practices other than those described in this manual may create a ﬁre hazard and void the limited warranty.

23. Do not make any make-shift compromises during installation. Any modiﬁcation or alteration may result in damage to the appliance or dwelling and will void the warranty, certiﬁcation and listings of this unit.

24. These appliances are designed as supplemental heaters. Therefore, it is advisable to have an alternate heat source when installed in a dwelling.

25. Do Not Overﬁre – If Heater or Chimney Connector Glows,

You Are Overﬁring.

26. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

27. DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS SUCH AS GASOLINE, NAPHTHA OR ENGINE OIL.

TESTING INFORMATION

This manual describes the installation and operation of these non-catalytic wood heaters. These heaters meet the U.S. Environmental Protection Agency’s emissions limits for wood heaters sold on or after July 1, 1990. This heater has been developed, tested and constructed in accordance with the requirements of UL 1482, ULC S627 and HUD standards and is listed by OMNI Test Laboratories, Portland, OR. It has been approved for residential, mobile home and alcove installations.

DRAFT REQUIREMENTS

W.C. As per NFPA-211 standard (see paragraph below), the installer

must take into account all variables within the installation and install the appliance in such a manner that satisﬁes the draft requirements of the appliance. See Chimney Guidelines below to assist you in selecting the proper venting system for your installation.

American National Standards Institute ANSI/NFPA 211, Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances

- See Draft Section: A chimney or vent shall be so designed and con-

structed to develop a ﬂow sufﬁcient to completely remove all ﬂue and vent gases to the outside atmosphere. The venting system shall satisfy the draft requirements of the connected appliance in accordance with the manufacturer’s instructions.

Your wood stove is dependent upon a properly functioning chimney for optimum performance. It is a high efﬁciency appliance that loses much less heat up the chimney than older appliances and ﬁreplaces. For this reason it is important to match the stove to the chimney. The chimney has two functions:

1. It draws combustion air into the appliance (without air, no fuel will burn) and

2. It exhausts combustion by-products. Your new appliance is what is known as a “natural draft” appliance.

The appliance depends solely on the natural draft of the chimney system to draw combustion air into the unit. Draft is the force that moves air from the appliance up into the chimney. The amount of draft in your chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too much draft may cause excessive temperatures in the appliance (overﬁring). Slow or inadequate draft equals poor combustion and possible smoking problems. The following are some conditions that may contribute to poor chimney draft:

1. A chimney too large for your appliance.

2. A chimney with not enough height to produce adequate draft.

3. A chimney with excessive height (this may allow exhaust to cool too much before exiting, which will stall the rate the exhaust exits).

4. Offsets in the venting system are too restrictive (see Chimney Guide- lines).

Inadequate draft will cause the appliance to leak smoke into the room through the stove and the chimney connector joints.

Excessive draft may cause an uncontrollable burn or a glowing red stove or chimney part.

Chimney Guidelines:

• This appliance requires approximately 12 feet minimum of “effective draw” provided by the venting system. As a rule of thumb, every 90 degree total direction change in the venting will result in a loss of approximately 5 feet of “effective draw.” Example: If two 45 degree offsets are used, subtract 5 feet from the actual vertical vent height to determine your “effective draw.” In this case if you had 14 feet of vertical vent, the effective draw would only be approximately 9 feet (14 ft. - 5 ft. = 9 ft.), therefore it may be necessary to add additional height to the venting system.

• Do not install an offset within the ﬁrst two feet above the ﬂue outlet on the appliance.

• If the venting system is all vertical and the total vent length above the ﬂue outlet exceeds 14 feet, it is recommended that the 8” to 6” pipe reducer is used (cat. no. 71134) and a 6” venting system be installed. At higher elevations, this may not be necessary.

• In well insulated and weather tight homes, it may be difﬁcult to establish a good draft up your chimney. The poor draft is caused by a shortage of air in the house. In this situation an Outside Air Kit may need to be installed (See Negative Pressure Warning on Page 5 and Outside Combustion Air on Page 11).

Chimney Height Requirements

The chimney must extend 3’ (.92m) above the level of roof penetration and a minimum of 2’ (.61m) higher than any roof surface within 10’ (3m) (see below). Check with your local building ofﬁcials for additional requirements for your area.

Overﬁring Damage - If the heater or chimney connector glows, you are overﬁring. Other symptoms may include: Cracking, warping or burning out of components, plated accessories may turn color, stove glass may develop a haze, which will not come off with cleaning.

Overﬁring of a stove is a condition where excessive temperatures are reached, beyond the design capabilities of the appliance. The damage that occurs from overﬁring is not covered under the manufacturer’s limited warranty.

Also see Troubleshooting on Page 20.

SELECTING THE PROPER VENTING SYSTEM

The appliance is merely one component of a larger system. The other equally important component is the venting system. This is necessary for achieving the required ﬂow of combustion air to the ﬁre chamber and for safely removing unwanted combustion byproducts from the appliance. If the venting system’s design does not promote these ends, the system may not function properly. Poorly functioning venting systems may create performance problems as well as be a safety hazard. A draft test should

read greater than .04’ W.C. (inches water column) and less than .08”

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Figure 1 - Chimney Height Requirements

To pass inspection in nearly any jurisdiction, the chimney must meet both safety and exhaust ﬂow requirements. The (3’ by) 2’ by 10’ rule applies to both masonry and factory-built chimneys.

* Ref. USA - National Standard, NFPA 211-latest edition and Canada National Standard CSA B365-01-latest edition. Vents installed with a listed cap shall terminate in accordance with the terms of the cap’s listings.

NEGATIVE PRESSURE WARNING

FUEL

This appliance is not designed to be operated in a negative pressure. In very airtight homes with large kitchen exhaust fans, furnace cold air returns, fresh air exchange systems and any other air system in close proximity to the heating appliance may create a negative pressure in the same room as the heating appliance. This can create dangerous back drafting of the stove and chimney joints, drawing combustion by-products into the home. Be sure your home has adequate makeup air to eliminate negative pressures caused by the above-mentioned sources. Outside air connected to the appliance probably will not resolve such a problem as the stove or ﬁreplace insert is not the source of negative pressure. Lennox Hearth Products accepts no liability for damages resulting from negative pressures described here.

Ventilation Requirements - Provide adequate air for combustion. The fresh air requirements of this appliance must be met within the space where it will be installed. Ventilation is essential when using a Solid-FuelBurning heater. In well insulated and weather tight homes, it may be difﬁcult to establish a good draft up the chimney (caused by a shortage of air in the home). The lack of air is caused by many common household appliances which exhaust air from the home (such as a furnace, heat pump, air conditioner, clothes dryer, exhaust fans, ﬁreplaces, and other fuel burning appliances). Also, the combustion process of this heater uses oxygen from inside the dwelling. If the available fresh air delivery in the dwelling is insufﬁcient to support the demands of these appliances, problems can result (i.e. excessive negative pressure can develop in the dwelling which will affect the rate at which this appliance can draft thus resulting in performance problems. To correct this problem it may help to open a window (preferably on the windward side of the house) or install an optional outside air kit.

CREOSOTE FORMATION AND NEED FOR REMOVAL

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney ﬂue of a slow-burning ﬁre. As a result, creosote residue accumulates on the ﬂue lining. When ignited, this creosote makes an extremely hot ﬁre. The chimney and chimney connector should be inspected at least once monthly during the heating season to determine if a creosote buildup has occurred. If creosote has accumulated (1/8” [3mm] or more), it should be removed to reduce the risk of a chimney ﬁre.

Establish a routine for the fuel, wood burner and ﬁring technique. Check daily for creosote build-up until experience shows how often you need to clean to be safe. Be aware that the hotter the ﬁre the less creosote is deposited, and weekly cleaning may be necessary in mild weather even though monthly cleaning may be enough in the coldest months. Contact your local municipal or provincial ﬁre authority for information on how to handle a chimney ﬁre. Have a clearly understood plan to handle a chimney ﬁre.

DISPOSAL OF ASHES

Ashes should be scooped out of a cool stove with a small metal shovel. Ashes should be placed in a metal container with a tight ﬁtting lid and moved outdoors immediately. Other waste shall not be placed in this container. The closed container of ashes should be placed on a non-combustible ﬂoor or on the ground, well away from all combustible materials, pending ﬁnal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all the cinders have thoroughly cooled. Ashes can ignite up to 72 hours after removal from the appliance.

This appliance is designed and engineered to burn, dry, well-seasoned wood only.

Dry, seasoned wood is that which has been cut, split and allowed to dry under a covered area where air is free to ﬂow and circulate under and around the wood (not under a tarp or plastic). Make sure wood is not stacked directly on the ground, it may absorb moisture from the ground. It should be allowed to dry in these conditions for a minimum of six months, preferably one year or more.

IT MUST BE UNDERSTOOD THAT WOOD CANNOT BE LEFT IN ANY KIND OF WET OR DAMP AREA OR IT WILL NEVER BECOME COMPLETELY SEASONED.

Your stove will not operate at the level that it is meant to unless you use seasoned, dry wood. Do not burn driftwood or wood that has been in salt water, doing so will void your warranty. Do not burn treated wood, coal, garbage, cardboard, solvents, or colored paper. Burning treated wood, garbage, solvents, or colored paper may result in the release of toxic fumes. This type of burning will also void your warranty.

Do Not store fuel within space heater installation clearances or within the space required for refueling and ash removal.

PAINT CURING

If your appliance has plated accessories, be sure to clean it with a household type glass cleaner and a very soft cloth to remove any ﬁngerprints and residues prior to the ﬁrst ﬁre and before any ﬁre if the gold has been handled or soiled. Do not close the door tightly during the “Burn-In Period.” Also, open the door frequently (every 5-10 minutes) to keep the gasket from adhering to the curing paint.

Ventilate the house well during these ﬁrst ﬁrings as the paint gives off carbon dioxide and unpleasant odors. It is recommended that persons sensitive to an imbalance in the indoor air quality avoid the stove during the curing process.

Your new appliance is painted with a High Temperature Paint that cures during the ﬁrst few ﬁrings. We recommend that you put your stove through a regimen of three burns. The ﬁrst two should last for 20 minutes each at 250 degrees ( the stove should be allowed to cool completely between each burn). The third should be a burn of at least 450 degrees F. for 45-60 minutes. The paint will become soft, gummy and emit non-toxic smoke during these burns. After the stove cools down for the third time, the paint will harden.

DO NOT BUILD A LARGE ROARING FIRE UNTIL

THIS CURING EFFECT IS COMPLETE OR YOU MAY DAMAGE THE FINISH OF YOUR STOVE. Spray can touch-ups should be done only

with a high temperature stove paint (cat. no. H8159), available from all Lennox Hearth Products dealers.

BURN-IN PERIOD

Please be patient with the heat output of your stove for the ﬁrst few weeks. The steel will go through a curing process that eliminates moisture, which is deep in the steel and ﬁrebrick. This moisture will reduce initial heat output of your stove and may make it difﬁcult to start. After you have broken in the paint on the stove it will be necessary to build hot ﬁres to thoroughly remove the moisture from the appliance. Running the stove with the draft fully open for 1 to 1-1/2 hours after starting and adding generous amounts of fuel during the ﬁrst week or two should complete the curing process. We recommend the use of a thermometer attached to the stove top or chimney. Temperatures on the connector pipe should run in the 250-600 degree range.

(DO NOT OVERFIRE THE STOVE

DURING THIS PROCESS. IF THE STOVE OR CHIMNEY BECOMES RED, REDUCE THE AMOUNT OF AIR ENTERING THE STOVE IMMEDIATELY).

CLEARANCES TO COMBUSTIBLES

WARNING: BE ABSOLUTELY SURE THE DISTANCE BETWEEN THE HEATER AND THE SURFACE OF ANY COMBUSTIBLE CONSTRUC-

TION IS NOT LESS THAN SHOWN IN THE FIGURES ON PAGE 7.

CHIMNEY INSTALLATION

• Install chimney as per manufacturer’s instructions. Some brands of pipe may require removal of the spacer ring in the ﬂue collar.

• All horizontal runs of pipe should be as short as possible and are required by NFPA No. 211 to have an upward pitch or rise in the same direction the smoke travels of no less than 1/4” to the linear foot. The connector pipe must meet minimum clearances in any direction to walls or other combustible materials. It must attach to a listed double wall metal chimney at least 6” in diameter or to a masonry chimney with a ﬂue passage of at least 48 square inches.

• It is required that a chimney connector pipe not extend further than the inner wall of the ﬂue when it is connected to a masonry chimney and that it either be cemented to the masonry or be installed without cement in a thimble connected to the masonry wall. When the connector is inserted into a thimble, the joint must be tight enough so that it will not be dislodged in normal use. Install connector at no less than the minimum clearances from the ceiling when using a 90-degree elbow to pass through combustible constructions.

• Chimney connector pipes should never pass through a ﬂoor, ceiling, ﬁre wall, partition, or combustible construction of any type unless certain precautions are taken. The best method is to use a listed thimble and a listed chimney in accordance with the manufacturer’s directions. NFPA No. 211 gives approved methods for passing a ﬂue pipe through combustible constructions (see Page 10).

LEG AND HEATSHIELD INSTALLATION

Residential and Mobile Homes - Bolting down and grounding of stove

are required only in mobile homes.

Open all cartons, if any and remove the contents upon receipt and check for any damaged or missing parts. If there is hidden damage, notify your freight company or Lennox Hearth Products dealer immediately.

CAUTION: Wear gloves during installation in case of sharp edges on the stove.

Leg Installation

1. Carefully place stove on its back. Be careful not to scratch the stove, use a piece of cardboard or carpet to protect the back of the stove.

2. Mount all four legs as shown in Figure 9.

Threaded Rod

3. First, screw the threaded rods into the holes at the four corners on the bottom of the stove. Screw the threaded rods into the ﬁrebox three full rotations or 3/16” to 1/4” (if the rear rods are screwed in too far they will lift the bricks off the bottom of the stove). Use a washer and nut to secure the leg. Be sure the legs are mounted squarely on the ﬁrebox bottom. Tighten nuts securely.

4. Use the two bolts and washers provided with the heatshield kit to mount the heatshield as shown in Figure 10.

5. Do not over tighten the heatshield mounting bolts as it may bend the heatshield.

OUTSIDE AIR KIT INSTALLATION

To install the “Outside Air Kit”, position the clip so that the nut is directly above the hole punched in the back of the heatshield (see Figure 11). Install the outside air adapter box on the stove by sliding it into the air channel located between the bottom heatshield and the stove bottom until the oblong ring is approximately 1/4” from the rear edge of the lower heatshield. Make sure the ring is facing down. Thread the bolt up through the nut in the clip until snug against the adapter box.
