2.1. TECHNICAL FEATURES


This fireplace is intended for use with the type of gas specified on the rating plate.

These fireplaces are approved for installations without changes at altitudes up to 2,000 feet (609
meters) in the U.S. and 1,370 meters (4,500 feet) in Canada.

If your system is installed at an altitude higher than 4,500 feet above sea level, please contact
your local authorities having jurisdiction over gas product installation to determine the specific
adjustments necessary at this higher altitude.

Fireplaces at 31,000 BTU/h or less are equipped with tempered glass. Tempered glass goes
through a quenching process (rapid cooling) that treats it to improve its mechanical properties; it
is more resistant than regular glass.

Fireplaces at 32,000 BTU/h are equipped with a glass-ceramic surface. Glass-ceramic is made
of microcrystals dispersed in a glassy phase. This particular structure gives this material higher
thermal shock resistance than tempered glass.
