RULES BEFORE YOUR FIRST FIRE.

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.

Page 3

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.

STARTING A FIRE

1. To start a ﬁ re in your ﬁ replace properly, ﬁ rst check the operation of the ﬂ ue damper.

To open the damper on the CST ﬁ replaces,

push the center damper handle straight up. To close pull handle down. See Figure 5

2. The grate in the ﬁ rebox should be centered on or over the bottom hearth so your ﬁ re can breath properly. Crumble and twist plenty of newspapers UNDER the grate and criss-cross some small dry kindling sticks on top of the paper or on the bottom of the grate.

3. Build a pyramid of three split logs (split will start much faster). Arrange the uneven wood to provide plenty of air space between.

4. Now, light the paper at both sides of the ﬁ rebox.

5. Close the screens to prevent the escape of sparks and embers.

6. Close the damper only when your ﬁ re is completely out and ashes are cold. Keep closed when ﬁ replace is not in use to prevent unnecessary loss of heated or cooled air.

GLASS DOORS

These ﬁ replaces come standard with bi-fold design glass door enclosures with tempered glass panes. Removal or modiﬁ cations to the standard glass doors may void your warranty

and cause a smoking condition.

CAUTION

If a smoking condition exists, glass doors should be closed during ﬁ replace operation.

CAUTION

Glass and metal frames get hot — Always use handles to open and close the doors.

WARNING

Be aware that safety glass is unpredictable when hot and may break, expelling hot glass into the room. Advise all family members to remain well away from the ﬁ replace when operating with doors closed to avoid any possible personal injury.

WARNING

These ﬁ replaces should be operated with both sets of glass doors fully closed. If the doors are left open or partially closed, gas and ﬂ ame may be drawn out of the ﬁ replace opening, creating risks of both ﬁ re and smoke. Refer to Figures 2 and 3 for proper operating conditions.

Care and Cleaning of Your Glass Doors

Never clean the glass when the doors are hot. Do not use ammonia or ammonia based glass or household cleaner to clean the glass or the door frame. An ammonia based cleaner will damage the ﬁ nish of your glass door.

In most cases, a clean dampened towel followed by a dry towel will clean the glass. To remove any stubborn stains from the glass, use a mild soap solution and a towel dampened with clean water and then dry with a clean dry towel.

Glass Door Operating Safety Precautions and Instructions

• The ﬁ re must always be conﬁ ned within the boundaries of the fuel grate.

• The ﬁ replace screens must always be closed whenever the ﬁ replace is operated.

• Never slam the glass door since it could cause the glass to break.

• Do not build excessively large or hot ﬁ res. Scorching or discoloring of the solid brass or plated brass trim could result.

• Extreme temperature changes can cause glass breakage — do not build a hot ﬁ re and close the glass doors if the doors are cold.

• If the tempered glass pane becomes scratched or chipped, it creates a weakness in the glass which can cause the glass to break when heated. Replace the pane of glass by contacting your nearest dealer or distributor.

Page 5

WARNING

These ﬁ replaces should be operated only with the doors fully closed (Figure 3).

CAUTION

Do not touch the doors with your hands while the ﬁ replace is in use. Always use door handles. Doors will become very hot when ﬁ replace is in use.

IMPORTANT

Plated polished brass glass doors may have a plastic covering over all brass pieces for protection during shipping and handling. The plastic covering should be removed after installation of the ﬁ replace before its use. Under the plastic covering is a protective lacquer coating which should not be removed. In some instances, if it is removed, irreversible damage to the brass ﬁ nish could occur. Refer to the following for speciﬁ c information on plated polished brass. Please understand that the heat of the ﬁ re will cause the protective lacquer ﬁ nish to slightly change to a light caramel color. Do not be alarmed as this is a normal occurrence.

COMBUSTION AIR

A proper amount of combustion air is important for your ﬁ replace. Fireplaces consume large amounts of oxygen. It is important to allow an adequate supply of air. If the ﬁ replace is not equipped with an outside air kit, it may not obtain sufﬁ cient amounts of combustion air from inside the house or structure in which it is installed. Therefore, the ﬁ re may draw from an outside air source and pull air in through the chimney. This may cause smoke spillage into the room.

Smoke spillage often occurs when a ﬁ re is ﬁ rst started, until the ﬁ replace and the chimney has had the opportunity to “come up to temperature” and to begin to function normally. If smoke spillage problems persist, a window may be opened just a crack to allow the proper ﬂ ow of combustion air to the ﬁ replace.

If your ﬁ replace is equipped with an outside combustion air kit, keep open at all times when ﬁ re is burning and close when ﬁ re is out to prevent cold air intrusion.

Combustion Air Control

The operation and location of the outside air control lever varies to some extent on different ﬁ replace models.

On the Custom Series ﬁ replaces, the control lever that operates the outside combustion air valve is located on one lower side behind the screen panel. Push the lever all the way in to close the air valve and pull the lever all the way out to open the air valve (Figure 4).

Closed

Open

Figure 4

The outside air damper should be kept closed on all ﬁ replaces except when the ﬁ replace is in operation. If there is no heat present in the ﬁ rebox, the air damper should be closed at night before retiring to prevent intrusion of outside air into the home.

DAMPER OPERATION

The damper is controlled through the use of a control lever located within the ﬁ rebox opening at the top center just behind the ﬁ rebox lintel (Figure 5). The control lever snaps into place at the extreme range of motion, up and back in the closed position. When pulled forward and down, the damper is open.

LINTEL EXTENSION

These Custom Multi-Open Factory-Built Fireplaces were designed, tested and listed with an 18" (457 mm) high viewing area, ﬂ oor to lintel. However, varying conditions such as altitude, climate, wood type, moisture content of fuel, dwelling design peculiarities, average ambient air pressure and humidity may effect the performance of this ﬁ replace. If an unacceptable amount of smoking occurs while the doors are open, the adjustable lintel can be moved to correct the smoking condition.

The lintel extension can be lowered using a predrilled hole located at the top of the lintel extension. See Figure 6.

To lower the lintel extension on Model CST38MH, remove the screw from each end of the lintel extension (located behind the screen assembly). Slide the lintel extension down and align the upper holes in the lintel extension with the holes in the lintel frame. Reattach using the screws previously removed. Repeat this procedure for the lintel extension on the opposite side of the ﬁ replace. See Figure 6.

Proper care and “burn-in” of the ﬁ rebox will prolong the period of enjoyment without extensive maintenance. For the ﬁ rst few uses, build small ﬁ res – not roaring infernos. The materials used in the refractories contain and absorb moisture. It is important to “cure” the refractories by building only modest ﬁ res.

Under normal usage, it is expected that hairline cracks will appear in the refractory surface. These hairline cracks do not affect the safe operation of the ﬁ replace.

Refractories should be replaced when:

1. The crack opens more than 1/4" (19 mm).

2. Pitting in the surface is extensive and pits become deeper than 3/16" (4.76 mm).

3. Any piece of refractory larger than 2" (51 mm) in radius and 3/16" deep becomes dislodged.

If your refractory has a crack less than 1/4" (19 mm) in width, a simple Refractory Patch Kit, Model RPK, can easily be used to ﬁ ll the crack and repair the refractory.

If conditions 1, 2 or 3 occur, the refractory should be replaced. For minor defects, repair as noted above.

MAINTENANCE GUIDELINES

Your ﬁ replace is designed to operate trouble-free with minimum maintenance. However, like any ﬁ ne appliance, it deserves and requires some housekeeping attention.

Your ﬁ replace will perform better, and certainly look more attractive to family and friends, if it is cleaned before each use. Before the ﬁ rst seasonal use in Autumn and after the last ﬁ re in Spring, it is important to inspect the ﬁ replace system carefully. We recommend at least two complete ﬁ replace inspections a year.

Before Each Use

Twice A Year Check-Up

Normally, twice a year, you should inspect your ﬁ replace following this list:

1. Inspect the opening in your chimney top

and remove any debris that could clog it. The cap is usually held in place by four (4) screws, which remove easily for checking or cleaning the full length of the ﬂ ue from above. Remove the chimney top while wearing gloves to guard against any sharp metal edges.

2. Inspect the entire ﬂ ue from the top down for

obstructions such as birds nests, leaves, etc. This may be done by using a ﬂ exible handled chimney cleaning brush. If the chimney contains offset/return elbows; a soft brush cleaning from the top down to any elbow and then from the ﬁ rebox up to the offset/return section is the proper method. The beam from a powerful ﬂ ashlight will help in this inspection.

3. Look up from inside the ﬁ replace (damper

open) to see any obstructions in the lower ﬂ ue area. If present, shut the damper and glass doors (if installed) to seal the ﬁ rebox and contain any soot that might fall. If your do not have glass doors installed, a damp sheet covering the ﬁ replace opening and sealed with masking tape will do. Then clean the ﬂ ue from the top down (if an offset system, clean per Step 2) using a proper size chimney brush with ﬂ exible pole sections. Don’t open the doors or remove the sheet until all soot has settled. Vacuum, don’t sweep.

4. Check the metal ﬂ ashing and seals around

your chimney. Seal any cracks or loose nailhead openings to prevent roof leaks.

5. Clean the ﬁ rebox thoroughly by using a soft

brush or equivalent.

WARNING

REFRACTORIES

All ﬁ reboxes contain a furnace refractory ﬂ oor. Some models also have refractory sides and backs. These refractories are reinforced with steel, but can be broken by improper use. Dropping logs on the bottom refractory and building ﬁ res directly against the refractories can cause premature burnout of these components. It may easily be repaired or replaced at costs far below repair and maintenance for masonry ﬁ replaces.

1. Clean the ﬁ rebox of excessive ashes. Some

owners prefer to leave a small layer to insulate the cold refractory below the grate which helps ﬁ re starting.

If your particular model ﬁ replace has a fac-

tory supplied grate attached, it is permissible to remove the grate for cleaning; however, the grate must be re-attached to the ﬁ replace before the next burn.

2. Keep the ﬁ replace screens clean so combustion air ﬂ ows freely.

3. Spot check the brick-like refractory for small cracks. Heat from the ﬁ re expands it slightly. When it cools, it contracts.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE

Continued overﬁ ring can permanently damage your ﬁ replace system. Some examples of overﬁ ring are:

• Burning quantities of scrap lumber, pine branches, paper or cardboard boxes which exceed the volume of the normal log ﬁ re.

• Burning trash, chemicals or chemically treated combustibles.

Page 7

Creosote Formation and 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 ﬂ ue of a slow-burning ﬁ re. As a result, creosote residue accumulates on the ﬂ ue lining. Creosote makes an extremely hot ﬁ re when ignited.

The chimney should be inspected at least twice yearly during the heating season to determine if a creosote build-up has occurred.

If creosote has accumulated, it should be removed to reduce the risk of a chimney ﬁ re.

6. Is a vent fan, exhaust hood or central heating/cooling system stealing combustion air from your ﬁ replace? If their volume is high enough, this can cause negative pressure and an unwanted downdraft – and smoking.

7. Is your wood fuel too wet or unseasoned?

Or does it contain some chemical substance that causes sputtering, smoking and toxic fumes?

8. Figure 7 illustrates the correct height of your chimney top. It is unlikely that your installation does not adhere to the installation instructions. However, if not correct, you could experience an unusual downdraft. Usually, the best solution is to increase the chimney height. This may also be necessary if nearby trees, adjoining roof lines or a hill is causing a downdraft condition.

9. Remember, your ﬁ replace has been designed as a supplemental heating device only, it is not intended to heat your entire home.

Less Than 10'

2' Min.

If creosote build-up is found, do not use chemical chimney cleaners that are poured on a hot ﬁ re. The manufacturer considers them dangerous and they generally only work on the ﬂ ue section nearest the ﬁ re, leaving the rest of the ﬂ ue unaffected. It is best to take the time to clean the ﬂ ue as previously described or have the chimney professionally cleaned by a qualiﬁ ed chimney sweep.

TROUBLESHOOTING

Note: "Smoke Free" operation is not warranted nor are we responsible for inadequate system draft, general construction conditions, inadequate chimney heights, adverse wind conditions and/or unusual environmental factors or conditions beyond our control.

If you do experience a problem, here are several things to check:

1. Remember – always check to ensure your

ﬂ ue damper is in the open position before lighting a ﬁ re!

2. When lighting your ﬁ re, a little smoke may

escape into the room – more likely if the chimney is cold. To correct this, hold a lighted newspaper up inside the ﬁ rebox near the open ﬂ ue damper. This will turn around any downdraft and clear the ﬂ ue of cold air. As your log ﬁ re burns below, the updraft will improve as the chimney heats up.

3. Is your ﬁ re too far forward? Move it toward

the back with your poker. Keep the ﬁ re well within the conﬁ nes of your fuel grate.

4. Keep your ﬁ re up on the grate and the refractor y

below free of excessive ashes. The ﬁ re needs plenty of air movement around the logs.

5. If smoking occurs an hour or two after

lighting the ﬁ re, perhaps your well-insulated house is too airtight and there is scarcely any way for replacement air to enter and feed the ﬁ re. Check to see if your outside combustion air kit (if installed) is open. Check outside to ensure no obstructions are in front of exterior air entry. Open a window slightly, open doors to one or two rooms and see if this stops the smoking.
