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.
