PRECAUTIONS

Note: These fireplace systems are not difficult to install. However, in the interest of safety, it is recommended that the installer be a qualified or certified “tradesman” familiar with commonly accepted fireplace installation and safety tech- niques as well as prevailing local codes.

The most important areas of concern dealing with the installation of factory-built fireplaces are clearances to combustible materials, proper assembly of component parts, height of the chimney system, the proper use of accesso- ries supplied by the manufacturer and the techniques employed in using finishing mate- rials applied to the wall surrounding the fire- place, hearth extensions and wall shields. Each of these topics will be covered in thorough detail throughout this manual. Please give each your special attention as you progress with your installation.

Note: Illustrations shown reflect “typical” installations with nominal dimensions and are for design and framing reference only. Actual installations may vary due to indi- vidual design preferences. However, always maintain minimum clearances to combus- tible materials and do not violate any specific installation requirements.

These fireplaces have been tested and listed by Warnock Hersey (Report No. J20017261-231) to U.L. standard 127. These units are intended for installation in residential homes and other buildings of conventional construction includ- ing commercial, not in mobile homes.

These fireplace systems are designed for in- stallation in accordance with the National Fire Protection Standard for chimneys, fireplaces and solid fuel burning appliances; NFPA 211 and in accordance with codes such as the BOCA Basic/National Codes, the Standard Me- chanical Code and the Uniform Building Codes.

WARNING: FAILURE TO USE MANUFAC- TURE PROVIDED PARTS, VARIATIONS IN TECHNIQUES AND CONSTRUCTION MA- TERIALS OR PRACTICES OTHER THAN THOSE DESCRIBED IN THIS MANUAL MAY CREATE A FIRE HAZARD AND VOID THE LIMITED WARRANTY.

When complete these fireplace systems con- sists of four basic “sub-systems”:

CLEARANCES AND HEIGHT

REQUIREMENTS

The fireplace may be placed on or near normal construction materials*. The combustion air kit, firestop spacer and roof flashing (not chase flashings) may be placed directly on or against normal construction materials.* The chimney and fireplace outer wrapper require a minimum 2" air space to combustibles. A combustible mantle may be installed 12" above the opening of the fireplace as per NFPA 211, Section 7- 2.3.3.

The minimum installed height of the completed fireplace system is 15' 0". The maximum height is 60' 0".

The fireplace and chimney system must be enclosed when installed in or passing through a living area where combustibles or people may come in contact with it. This is important to prevent possible personal injury or fire hazard.

For questions, please call your distributor or the manufacturer. Special restrictions apply to the front and facing of the fireplace and nearby walls (See pages 16 and 17 ).
