WARNING!
This fireplace is tested and listed for use only with the optional accessories listed in these instructions. Use of
optional accessories not specifically tested for this appliance could void the warranty and/or result in a safety
hazard.
Safety Precautions
1. Please read these installation instructions completely before beginning installation procedures. Failure to follow them
could cause a fireplace malfunction resulting in serious injury and/or property damage.
2. Always check your local building codes prior to installation. The installation must comply with all local, regional, state
and national codes and regulations.
3. An adequate supply of replacement combustion air from outside the house must be available to the fire for the
fireplace to operate properly. To achieve this, the use of the optional outside air kit is highly recommended.
In the event the home is unusually tightly sealed, the optional combustion air kit may not provide all the air required
to support combustion. Hearth & Home Technologies 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.
4. The fireplace must be installed with the Hearth & Home Technologies SL Series Chimney System.
The chimney system must always terminate outside the building. Be sure to follow all chimney specifications given in
these installation instructions.
5. NEVER leave children unattended when there is a fire burning in the fireplace.
6. This fireplace is built for solid fuel only. NEVER use gasoline, gasoline type lantern fuel, kerosene, charcoal light fluid,
or similar liquids in this fireplace. Keep any flammable liquids a safe distance from the fireplace.
7. DO NOT use chimney cleaners or flame colorants in your fireplace.
8. The flue damper must be open at all times when the fireplace is in use.
9. While servicing this fireplace, always shut off any electricity or gas to the fireplace. This will prevent possible electric
shock or burns. Also, make sure the fireplace is completely cooled before servicing.
10. 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 burning season. See “Maintenance Instructions” in this manual
for cleaning instructions.
