Continuous Pilot Ignition / Intermittent Pilot Ignition Switch
These fireplaces have a continuous pilot ignition (CPI) / intermittent pilot ignition (IPI) switch installed under the
door. This switch allows the pilot to be switched from intermittent mode to continuous mode:
• Intermittent Mode—The pilot is extinguished when the fireplace is OFF.
• Continuous Mode—The pilot stays ON when the fireplace is OFF.
In periods of extreme cold, condensation may form on the glass door when the fireplace is OFF and the pilot is in
intermittent mode. Also, with the pilot in intermittent mode, the fireplace may cycle startup (i.e., the pilot and burner ignite,
but the burner extinguishes and reignites several times until the flue reaches the temperature for proper drafting).
• To save energy—switch to intermittent mode.
• For a standing pilot that will help prevent glass door condensation and cycle startup—switch to continuous mode.
NOTE: Continuous mode is indicated by a pilot that comes ON and remains lit when the fireplace is OFF.

Installing the Glass Media
WARNING
• The glass media was designed to provide a safe, reliable, attractive flame. Any attempt to use media not specified for
this fireplace will result in incomplete combustion, sooting, poor flame quality, and will void the warranty.
• Glass media gets very HOT during fireplace use and will remain hot up to ONE HOUR after gas supply is turned
off. HANDLE MEDIA ONLY WHEN COOL. Turn OFF all electricity to the appliance before installing media.
• If glass media is not installed according to the installation instructions, flame impingement and improper combustion could
occur, resulting in soot and/or excessive production of carbon monoxide (CO), a TOXIC gas that is colorless and odorless.
• This appliance is NOT designed to burn wood. Any attempt to burn wood in this fireplace may be a safety
hazard, cause irreparable damage the appliance, and void the warranty.
1. Install the glass media in the recessed area between the front and rear floors.
NOTE: 42” fireplaces require a full bag of glass media. 54” fireplaces require two (2) full bags of media.
