Install the Logs and Glowing Embers
• Turn OFF all gas and electricity to the appliance before installing the 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. 0• 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: It is important to ensure proper log placement per the manual when installing these units. Verify pilot
flame is not obstructed. See Verifying Appliance Operation on Pages 41-42.
