IMPORTANT: PLEASE READ AND UNDERSTAND THESE RULES TO FOLLOW FOR SAFETY.

1.Before starting your fireplace installation, read these installation instructions carefully to be sure you understand them completely and in entirety. Failure to follow them could cause a fireplace malfunction resulting in serious injury and/or property damage.

2.Always check your local building codes. The installation must comply with all local, regional, state and national codes and regulations.

3.These fireplaces must be installed with Security Chimneys FTF10 (10" inside diam- eter) Chimney System only. These systems are intended for use in any application where a traditional masonry type fireplace would apply. The chimney system must always vent to the outside of the building.

4.To ensure a safe fireplace system and to prevent the build-up of soot and creosote, inspect and clean the fireplace and chimney prior to use and periodically during the heating season.

5.Use solid fuel only. DO NOT use artificial wax based logs, chemical chimney cleaners or flame colorants in your fireplace.

6.DO NOT use charcoal or coal under any circumstances.

7.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 at safe distance from the fireplace.

8.NEVER leave children unattended when there is a fire burning in the fireplace.

9.Always keep flue damper open when heat is present in the fireplace.

10.Before servicing, allow the fireplace to cool. Always shut off any electricity or gas to the fireplace while working on it. This will prevent any possible electrical shock or burns.

11.This fireplace is not intended to heat an entire home or be used as a primary heat source. It is designed to ensure homeowner comfort by providing supplemental heat to the room.

12.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, the op- tional 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.

13.DO NOT use a fireplace insert or any other products not specified herein by the manufac- turer for use with this fireplace. All gas log sets must be operated with the damper clamped open, including unlisted “vent free” log sets. Listed “vent-free” log sets may be operated with the damper closed.

14."Smoke free” operation is not warranteed nor are we responsible for inadequate system draft caused by mechanical systems, general construction conditions, inadequate chimney heights, adverse wind conditions and/or un- usual environmental factors or conditions be- yond our control.

15.Never, under any circumstances, install a fireplace, chimney component or any acces- sories, that has visible or suspected physical damage as a result of handling or transporta- tion. These items should be inspected by your distributor or qualified factory representative to ensure safe condition. When in doubt, con- sult your distributor.

16.For additional safety considerations and complete operating instructions, refer to the Care and Operation Manual provided with the fireplace.
