SAFETY PRECAUTIONS

WARNING

To avoid the risk of damaging ﬁ replace materials and increasing the risk of ﬁ re, do not use the ﬁ replace to cook or warm food.

NEVER LEAVE CHILDREN UNATTEND-

ED WHEN THERE IS A FIRE BURNING IN THE FIREPLACE.

2. When burning wood, use SOLID NATURAL DRY WELL-SEASONED WOOD ONLY.

Hardwoods are recommended (soft woods tend to burn very quickly).

• DO NOT burn treated wood, charcoal, coal, trash, driftwood, woods dipped in tar, Christmas tree greens, pitch, pine tar, creosote, chemical chimney cleaners, ﬂ ame colorants, polystyrene packaging, wood products with synthetic binders (i.e. plywood). Plywood, lumber and other misc. materials can produce abnormally high temperatures, sputtering and smoking ﬁ res and may contain hazardous chemicals to treat insects and fungus.

• When using newspapers to start a wood ﬁ re, remove (and do not burn) the colored comic or ad sections. The colored inks may contain lead and can produce toxic gases.

• If Artiﬁ cial Logs are burned it is required that the logs are UL safety listed (see labeling or documention provided with logs). Read and follow the log manufacturer's instructions. Do not treat artiﬁ cial logs (made from sawdust and wax) the same way you treat real natural wood logs. Use only one at a time.

• IMPORTANT: Burning unapproved fuels can produce excessive temperatures, beyond the design capabilities of the ﬁ replace and may produce excess sparks or may contain hazardous chemicals. Burning unapproved

fuels can result in a chimney ﬁ re, a house ﬁ re, personal injury, death or loss of property.

3. NEVER use gasoline, gasoline-type lantern

fuel, kerosene, charcoal lighter ﬂ uid, or similar liquids to start or “freshen up” a ﬁ re in this ﬁ replace. Keep any ﬂ ammable liquids a safe distance from the ﬁ replace.

4. Keep the chimney damper open while any ﬁ re or smoldering embers are present .

5. Never block or restrict the room air intake grille across the bottom front or the warm air outlet grille across the top front of the ﬁ replace.

6. With the ﬁ re burning, close the protective mesh screens to keep sparks and embers INSIDE the ﬁ rebox.

7. Keep any combustible furniture or decorative pillows at least 36" (914 mm) on the sides and 60" (1524 mm) to the front (from the ﬁ replace opening).

8. Never leave your ﬁ replace unattended while it is burning.

9. Be careful adding wood fuel to the ﬁ re or handling ﬁ replace tools such as shovels, tongs or pokers.

10. Never modify or alter your ﬁ replace system in any way. To do so may create a potential ﬁ re hazard and void the Limited Warranty.

11. The bottom refractory can be cracked by excessive abuse such as tossing heavy logs onto the grate or gouging with ﬁ replace tools. Exercise caution when adding wood to your ﬁ replace.

12. Fireplace Inserts - Contact your dealer or distributor for a list of Lennox ﬁ replace inserts approved for installation into your ﬁ replace. DO NOT install a ﬁ replace insert from any another manufacturer.

13. If you are using your ﬁ replace as a “decorative appliance”, such as with a permanently installed vented gas log set,

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE

the ﬁ replace damper must be permanently

ﬁ xed in the open position.

WARNING

This ﬁ replace has not been tested with an unvented gas log set. To reduce risk of ﬁ re or injury, do not install an unvented gas log set into this ﬁ replace.

14. Always ensure that an adequate supply

of replacement combustion air from the outside of the house is accessible to the ﬁ re to support normal combustion. Fireplaces consume large volumes of air during the normal combustion process. In the event the home is tightly sealed with modern energy efﬁ cient features, an optional combustion air kit may not provide all the air required to support combustion. The manufacturer is not responsible for any smoking or related problems that may result from the lack of adequate combustion air. It is the responsibility of the builder/contractor to ensure that adequate combustion air has been provided for the ﬁ replace.

15. The manufacturer does not warranty “smoke

free” operation nor are we responsible for inadequate system draft caused by mechanical systems, general construction conditions, inadequate chimney heights, adverse wind conditions and/or unusual environmental factors or conditions beyond our control.

GENERAL INFORMATION

1. The all-steel, multi-wall ﬁ rebox is the heat

center of the system. It is well insulated for safe clearance to combustibles.

2. The hearth ﬂ oor of the ﬁ rebox is a brick pat-

tern reinforced refractory base for your ﬁ re. On certain models, the sides and rear of the ﬁ rebox are also refractory for authenticity and safety.

3. The metal chimney sections extending from

the ﬁ rebox top to beyond your roof are two walled and air-cooled. The inner passage, or ﬂ ue, provides the exit for smoke and gases.

4. The ﬂ ue damper is either fully open or fully

closed by the handle you ﬁ nd in the center and top of the ﬁ rebox. It must be open when ﬁ re is present so smoke and gases can escape. It should be closed only when the ﬁ re is completely out – keeping room air from being lost up the ﬂ ue.

5. Closed screens prevent ﬁ re, sparks and

embers from popping out of the ﬁ rebox while a ﬁ re is burning. Pull screens back when adding wood to the ﬁ rebox.

6. Why use a fuel grate? Besides positioning

the ﬁ rebed properly, it protects the refractory ﬂ oor, back and sides of the ﬁ replace. Further, it ensures a proper ﬂ ow of combustion air into and around the ﬁ rebed. The grate must be used at all times when burning. Your warranty may be voided without the use of this grate.

7. Remember, your ﬁ replace is not intended to

heat your entire home. Their unique designs are intended for architectural, decorating and aesthetic considerations. Using this ﬁ replace to heat large areas may lead to overﬁ ring and void your warranty.

FUELS Never Use Coal in Your Fireplace

Your ﬁ replace system is not designed to be used with coal derivative products. The combustion process of certain types of coal can deposit corrosive materials in the ﬁ replace and chimney system which can lead to premature product failure. Never use coal as a fuel in this ﬁ replace system.

DECORATIVE GAS LOG SETS

If your ﬁ replace system was installed with a gas line and you wish to install a decorative gas appliance (gas log set), it must contain an automatic shut-off device and be installed in accordance with

CAUTION

When using the decorative gas appliance, the ﬁ replace damper must be set in the fully open position.

WARNING

This ﬁ replace has NOT been tested with an unvented gas log set. To reduce risk of ﬁ re or injury, do not install an unvented gas log set into this ﬁ replace.

Wood Fuel Pointers

Wood is a wonderful renewable fuel source. Normally it burns clean, leaving only a minimum of waste ash, provides comforting heat and can provide a variety of aromas and visual images.

You will want to know which woods are best for use. Sometimes you may want a quick, short ﬁ re to offset a morning chill. Soft woods are preferable in this case. Other times you would want more slow burning and a uniform heat output. Hardwoods are preferable for this use.

The amount of heat available from the logs will be about equal on a weight basis. However, logs are generally not weighed so the amount of heat will depend on:

1. The type of wood used.

2. How dry it is.

3. How many logs you put in.

4. The size of the logs.

The last statement means that one big log weighing 10 pounds has as much heating potential as 10 pounds of twigs. However, air cannot get at the solid log to feed the ﬁ re so the solid log will burn slowly. While you would get the same amount of heat out of either ﬁ re, the smaller the pieces of wood and the more air space around them, the faster the ﬁ re will burn.

DISPOSAL OF ASHES

Ashes should be placed in a metal container with a tight ﬁ tting lid. The closed container of ashes should be placed on a non-combustible ﬂ oor or on the ground, well away from all combustible materials, pending ﬁ nal disposal. If the ashes are to be disposed of by burial in soil or other wise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

SOFTWOOD VS HARDWOOD

Softwoods contain about 15 percent highly ﬂ ammable resin which generates creosote soot in the chimney ﬂ ue. Burning softwood exclusively may not be as desirable nor as safe as burning denser hardwoods. Many experienced ﬁ re-builders use small amounts of softwood kindling and newspaper in conjunction with starting a ﬁ re with split hardwood logs. Here are some guidelines to remember:

1. Softwoods produce fast warming and shorter ﬁ res. Hardwoods burn less vigorously, have shorter ﬂ ames and produce steady, glowing coals.

2. As a general rule, denser woods contain more potential heat per pound. Most softwoods offer moderate heat value per pound.

3. Different woods vary widely in ﬂ ame heights, ﬂ ame intensities, smoke characteristics and in sparking. Most hardwoods do not spark.

4. Most freshly cut “green” wood will not burn well and will smoke. Green wood can be from 10 to 40 percent less efﬁ cient than air-dried seasoned wood.

5. Moisture and resin found inside unseasoned wood cells will build up pressure under heat and explode as sparks.

6. Most wood needs to be seasoned 9 to 12 months to reduce the moisture content and produce good steady ﬁ res. When moisture content is reduced from 60 to 20%, the gain in heat potential is nearly 7%.

7. Proper storage of wood, especially during seasoning, is essential. We recommend that you:

a. Never store wood on the ground. This will

cause rotting and insect inﬁ ltration. Raise wood on ﬂ at rock or scrap wood.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE

b. Stack wood loosely to allow air circulation.

c. Store wood where it will not be excessively exposed to weather, such as under a tarp or under a roof.

d. Do not stack wood directly against the

walls of your home.

8. Be a knowledgeable wood buyer.

• There is a difference in cord sizes. A standard cord stack of logs is 4 ft. high by 8 ft. long by 4 ft. deep or the equivalent of this cubic footage. A face cord is the same height and length as a standard cord but the depth is only the length of the logs (12, 18 or 24 inches). A face cord can contain as little as 25% of the wood found in a standard cord.

• If you buy by the ton, remember that wood becomes lighter as it dries. When buying green or wet wood, ask for some extra poundage to allow for the extra water you will be getting.

9. When comparing woods of the same moisture content and same species, we ﬁ nd most woods have approximately the same heating potential per pound. However, most wood is sold by volume, not by weight. To determine the best heating source, look at the density of various wood types. (Density is the weight for a given size). The higher the density, the more potential heat output. A standard cord has a volume of 128 cubic feet. This ﬁ gure also includes the air space between and around the wood. The actual volume in a standard cord is between 60 and 100 cubic feet; depending on how tightly the wood is packed. Assuming that you are comparing two standard cords of different species but the same volume and moisture content, the denser species will provide more BTU’s. The table of wood species/densities reveals more helpful guidelines.
