GENERAL SAFETY PRECAUTIONS IMPORTANT! READ AND UNDER- STAND 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, pro- duce abnormally high temperatures and sputtering, smoking fires. When burning arti- ficial 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 IN- SIDE the firebox.

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. Exer- cise 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 “deco- rative 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 op- tional combustion air kit may not provide all the air required to support combustion. The manufacturer is not responsible for any smok- ing or related problems that may result from the lack of adequate combustion air. It is the responsibility of the builder/contractor to en- sure that adequate combustion air has been provided for the fireplace.

14.The manufacturer does not warranty “smoke free” operation nor are we responsible for inad- equate system draft caused by mechanical systems, general construction conditions, in- adequate chimney heights, adverse wind conditions and/or unusual environmental fac- tors 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.

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 com- bustion 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 Na- tional 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.
