GENERAL SAFETY PRECAUTIONS IMPORTANT! READ AND UNDER­STAND BEFORE YOUR FIRST FIRE.
1. Use SOLID WOOD only for fuel. It is best to
use dry and well seasoned hardwood. Soft woods tend to burn very quickly. DO NOT use treated wood, charcoal, coal, trash, driftwood or woods that have been dipped in tar, pitch, pine tar, creosote, etc. Wood products made with synthetic binders, such as plywood, pro­duce abnormally high temperatures and sputtering, smoking fires. When burning arti­ficial logs, please read and follow the instructions provided by the manufacturer.
Never burn treated construction lumber or scraps. These woods burn excessively hot and may contain chemicals used to treat insects and fungus. When burned, these chemicals can pose a significant hazard.
2. NEVER use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this fireplace. Keep any flammable liquids a safe distance from the fireplace.
3. Keep the chimney damper open while any fire or smoldering embers are present .
4. 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 fireplace.
5. With the fire burning, close the protective mesh screens to keep sparks and embers IN­SIDE the firebox.
2
6. Keep any combustible furniture or decora-
tive pillows at least 36" (914 mm) from the fireplace opening.
7. Never leave your fireplace unattended while it is burning.
8. Be careful adding wood fuel to the fire or handling fireplace tools such as shovels, tongs or pokers.
9. Never modify or alter your fireplace system in any way. To do so may create a potential fire hazard and void the Limited Warranty.
10. The bottom refractory can be cracked by excessive abuse such as tossing heavy logs onto the grate or gouging with fireplace tools. Exer­cise caution when adding wood to your fireplace.
11. DO NOT use a fireplace insert or any other product not specified by the manufacturer for use with this fireplace.
12. If you are using your fireplace as a “deco­rative appliance”, such as with a permanently installed gas log set, the fireplace damper must be permanently fixed in the open position.
13. Always ensure that an adequate supply of replacement combustion air from the outside of the house is accessible to the fire 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 efficient 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 fireplace.
14. 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 firebox is the heat
center of the system. It is well insulated for safe clearance to combustibles.
2. The hearth floor of the firebox is a brick pattern reinforced refractory base for your fire. On certain models, the sides and rear of the firebox are also refractory for authenticity and safety.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE
3. The metal chimney sections extending from the firebox top to beyond your roof are two walled and air-cooled. The inner passage, or flue, provides the exit for smoke and gases.
4. The flue damper is either fully open or fully closed by the handle you find in the center and top of the firebox. It must be open when fire is present so smoke and gases can escape. It should be closed only when the fire is completely out – keeping room air from being lost up the flue.
5. Closed screens prevent fire, sparks and embers from popping out of the firebox while a fire is burning. Pull screens back when adding wood to the firebox.
6. Why use a fuel grate? Besides positioning the firebed properly, it protects the refractory floor, back and sides of the fireplace. Further, it ensures a proper flow of combustion air into and around the firebed. The grate must be used at all times when burning. Your warranty may be voided without the use of this grate.
7. Remember, your fireplace is not intended to heat your entire home. Their unique designs are intended for architectural, decorating and aesthetic considerations.
FUELS Never Use Coal in Your Fireplace
Your fireplace 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 fireplace and chimney system which can lead to premature product failure. Never use coal as a fuel in this fireplace system.
Decorative Gas Log Sets
If your fireplace 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 local codes and/or the Na­tional Fuel Gas Code, ANSI Z223.1A and NFPA-54-1988.
CAUTION: WHEN USING THE DECORATIVE GAS APPLIANCE, THE FIREPLACE DAMPER MUST BE SET IN THE FULLY OPEN POSITION.
WARNING: THIS FIREPLACE HAS NOT BEEN TESTED WITH AN UNVENTED GAS LOG SET. TO REDUCE RISK OF FIRE OR INJURY, DO NOT INSTALL AN UNVENTED GAS LOG SET INTO THIS FIREPLACE.
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 fire 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 fire so the solid log will burn slowly. While you would get the same amount of heat out of either fire, the smaller the pieces of wood and the more air space around them, the faster the fire will burn.
Disposal of ashes
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are 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 flammable resin which generates creosote soot in the chimney flue. Burning softwood exclu­sively may not be as desirable nor as safe as burning denser hardwoods. Many experienced fire-builders use small amounts of softwood kindling and newspaper in conjunction with starting a fire with split hardwood logs. Here are some guidelines to remember:
1. Softwoods produce fast warming and shorter fires. Hardwoods burn less vigorously, have shorter flames 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 flame heights, flame 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 efficient 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 fires. 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 infiltration. Raise wood on flat rock or scrap wood.
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 find 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 figure 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.

STARTING A FIRE
1. To start a fire in your fireplace properly, first
check the operation of the flue damper.
WARNING: THE CR SERIES FIREPLACES SHOULD BE OPERATED WITH THE DOORS FULLY OPEN OR FULLY CLOSED. IF THE DOORS ARE LEFT PARTIALLY OPEN, GAS AND FLAMES MAY BE DRAWN OUT OF THE OPENING, CREATING RISKS OF BOTH FIRE AND SMOKE. REFER TO
FIGURE 2
FOR PROPER OPERATING CONDITIONS.
The design of the flue damper assembly varies for some model fireplaces. For the standard corner opening fireplaces (CR Series) the damper is activated by a center mounted handle. The damper is opened by pulling the handle forward. To close, the handle is pushed all the way to the back of the firebox. The damper is NOT ADJUST­ABLE between the open and closed position.
To open the damper on the CST and CPF fireplaces, push the center damper handle straight up. To close pull handle down.
2. The grate in the firebox should be centered on or over the bottom hearth so your fire 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 firebox.
5. Close the screens to prevent the escape of sparks and embers.

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 finish 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 fire must always be confined within the boundaries of the fuel grate.
• The fireplace screens must always be closed whenever the fireplace is operated.
• Never slam the glass door since it could cause the glass to break.
6. Close the damper only when your fire is completely out and ashes are cold. Keep closed when fireplace is not in use to prevent unneces­sary loss of heated or cooled air.
GLASS DOORS
The required glass door enclosures come in two different styles; “All-Glass and bi-fold design with tempered glass panes. Removal or modifications to the glass doors may void your warranty and cause a smoking condition.

• Do not build excessively large or hot fires. 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 fire 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.

ADVISE ALL FAMILY MEMBERS TO REMAIN WELL AWAY FROM THE FIREPLACE WHEN OPERAT­ING WITH DOORS CLOSED TO AVOID ANY POSSIBLE PERSONAL INJURY.
COMBUSTION AIR
A proper amount of combustion air is impor­tant for your fireplace. Fireplaces consume large amounts of oxygen. It is important to allow an adequate supply of air. If the fireplace is not equipped with an outside air kit, it may not obtain sufficient amounts of combustion air from inside the house or structure in which it is installed. Therefore, the fire 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 fire is first started, until the fireplace 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 flow of combustion air to the fireplace.
On the CR Series fireplaces, the control lever that operates the outside combustion air valve has been pre-installed on your fireplace. A coverplate has been mounted over this control lever only if the outside air kit has not been attached. The control lever is located on the closed end of the fireplace opening behind the screen. To open the air damper, turn the lever handle 1/2 turn counter clockwise (or until lever can be moved upward), then re-tighten at desired open position. To close damper, re­verse procedure (
Figure 5
).
Control Lever
Figure 5
On the Merit Series fireplaces, 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 open the air valve and pull the lever all the way out to close the air valve (

Figure 6
).
LINTEL EXTENSION
These Merit Multi-Open Factory-Built Fireplaces were designed, tested and listed with an 18" (457 mm) high viewing area, floor 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 fireplace. 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 a maxi­mum of 2" (51 mm) using a predrilled hole located at the top of the lintel extension. To lower the lintel extension 1" (25 mm), drill a 1/8" (3 mm) hole where the dimple is located. (See
Figure 7
.)
To lower the lintel extension on Model CST-38, remove the two screws from both ends of the lintel extension (located behind the screen assembly). Slide the lintel extension down and align the desired 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 fireplace. (
Figure 7
)
If your fireplace is equipped with an outside combustion air kit, keep open at all times when fire is burning and close when fire 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 fireplace models.
Closed
Figure 6
The outside air damper should be kept closed on all fireplaces except when the fireplace is in operation. If there is no heat present in the firebox, the air damper should be closed at night before retiring to prevent intrusion of outside air into the home.

On Model CPF-38 the two (2) side lintel exten­sions are welded to the end lintel extension. The lintel extension lowers similarly to the CST-38 lintel extension. However, to prevent the end lintel extension from being misshaped, follow the following steps while referring to
Figure 7
.

1. Remove the two (2) screws from one of the
side lintel extension, leaving the lintel extension on the other side attached to the lintel frame. Only lower the end of the lintel extension closest to the closed end (refractory wall) of the CPF-
38. Aligning the desired holes in the lintel extension with the holes in the lintel frame and reattach using one (1) of the screws previously removed.
2. Remove the two (2) screws from the lintel extension on the other side of the fireplace. Lower the whole lintel extension to the desired holes and reattach using the screws just re­moved.
3. On the lintel extension first lowered, realign the holes as necessary then insert and tighten the remaining screw.
REFRACTORIES
All fireboxes contain a furnace refractory floor. 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 fires 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 fireplaces.
Proper care and “burn-in” of the firebox will prolong the period of enjoyment without exten­sive maintenance. For the first few uses, build small fires – not roaring infernos. The materials used in the refractories contain and absorb moisture. It is important to “cure” the refracto­ries by building only modest fires.
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 fireplace.
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 fill 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 fireplace is designed to operate trouble­free with minimum maintenance. However, like any fine appliance, it deserves and requires some housekeeping attention.
Your fireplace will perform better – and cer­tainly look more attractive to family and friends – if it is cleaned before each use. Before the first seasonal use in Autumn and after the last fire in Spring, it is important to inspect the fireplace system carefully. We recommend at least two complete fireplace inspections a year.
Before Each Use
1. Clean the firebox of excessive ashes. Some
owners prefer to leave a small layer to insulate the cold refractory below the grate which helps fire starting.
If your particular model fireplace has a factory supplied grate attached, it is permissible to remove the grate for cleaning; however, the grate must be re-attached to the fireplace be­fore the next burn.
2. Keep the fireplace screens clean so combus­tion air flows freely.
3. Spot check the brick-like refractory for small cracks. Heat from the fire expands it slightly. When it cools, it contracts.
Twice A Year Check-Up
Normally, twice a year, you should inspect your fireplace 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 flue from above. Remove the chimney top while wearing gloves to guard against any sharp metal edges.
2. Inspect the entire flue from the top down for obstructions such as birds nests, leaves, etc. This may be done by using a flexible 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 firebox up to the offset/return section is the proper method. The beam from a powerful flashlight will help in this inspection.
3. Look up from inside the fireplace (damper open) to see any obstructions in the lower flue area. If present, shut the damper and glass doors (if installed) to seal the firebox and contain any soot that might fall. If your do not have glass doors installed, a damp sheet covering the fire­place opening and sealed with masking tape will do. Then clean the flue from the top down (if an offset system, clean per Step 2) using a proper size chimney brush with flexible pole sections. Don’t open the doors or remove the sheet until all soot has settled. Vacuum, don’t sweep.
4. Check the metal flashing and seals around your chimney. Seal any cracks or loose nailhead openings to prevent roof leaks.
5. Clean the firebox thoroughly by using a soft brush or equivalent.
WARNING: CONTINUED OVER FIRING CAN PERMANENTLY DAMAGE YOUR FIREPLACE SYSTEM. SOME EXAMPLES OF OVERFIRING ARE:
• BURNING QUANTITIES OF SCRAP LUMBER, PINE BRANCHES, PAPER OR CARDBOARD BOXES WHICH EXCEED THE VOLUME OF THE NORMAL LOG FIRE.
• BURNING TRASH, CHEMICALS OR CHEMICALLY TREATED COMBUS­TIBLES.
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 flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. Creosote makes an extremely hot fire 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 fire.
If creosote build-up is found, do not use chemical chimney cleaners that are poured on a hot fire. The manufacturer considers them dangerous and they generally only work on the flue section nearest the fire, leaving the rest of the flue unaffected. It is best to take the time to clean the flue as previously described or have the chimney professionally cleaned by a quali­fied chimney sweep.

TROUBLE SHOOTING No Smoking Allowed
Your new fireplace is designed not to smoke if properly installed and operated per our instruc­tions. If you do experience a problem, here are several things to check:
1. Remember – always check to ensure your flue damper is in the open position before lighting a fire!
2. When lighting your fire, 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 firebox near the open flue damper. This will turn around any down­draft and clear the flue of cold air. As your log fire burns below, the updraft will improve as the chimney heats up.
2' Min.

3' Min.
6. Is a vent fan, exhaust hood or central
heating/cooling system stealing combustion air from your fireplace? 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 8
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.

To ensure warranty and to prevent a potential fire hazard, do not use any other doors on these appliances.
3. Is your fire too far forward? Move it toward
the back with your poker. Keep the fire well within the confines of your fuel grate.
4. Keep your fire up on the grate and the refrac­tory below free of excessive ashes. The fire needs plenty of air movement around the logs.
5. If smoking occurs an hour or two after lighting the fire, perhaps your well-insulated house is too airtight and there is scarcely any way for replacement air to enter and feed the fire. 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.
9. Remember, your fireplace has been de­signed as a supplemental heating device only, it is not intended to heat your entire home.
