Install the Logs, Volcanic Stone, and Glowing Embers
WARNING
• Turn OFF all gas and electricity to the appliance before installing the volcanic stone, embers, and logs.
• Do NOT install the logs until the appliance has been completely installed, the gas line connected and
tested for leaks, and the initial burner operation has been confirmed.
• Use of an unapproved log set in the fireplace will void the warranty and will result in incomplete
combustion, sooting, and poor flame quality.
• Logs get very hot and remain hot for up to one hour after the gas supply is turned OFF. Handle the logs
only when cool.
• This appliance is not designed to burn wood. Any attempt to do so could cause irreparable damage to
appliance and prove hazardous.
• If the logs are not installed according to these instructions, improper combustion could occur. This could
result in the excessive production of soot and/or the colorless, odorless, toxic gas carbon monoxide (CO).
NOTE: If applicable, install the firebox liner before placing the stone. Logs can be installed after the volcanic stone.
NOTE: It is important to ensure proper log and or media placement per the manual when installing these units.
Verify pilot flame is not obstructed. Ensure media does not fall inside the bracket or through the pilot hole in the
floor (see Figure 43B). See Verifying Appliance Operation on Pages 40-41.
Installing the volcanic stone, and glowing embers
1. If necessary, remove the glass door (Pages 59-60).
2. Spread the decorative volcanic stone in a pleasing pattern on the firebox floor along the slope and to the back
right and left sides of the burner (Figure 41).
NOTE: Do not place stone on the burner.
3. Separate and fluff the glowing embers into pieces approximately the size of a quarter (Figure 42).
