WARNING
• DO NOT attempt to install the logs until the
appliance installation has been completed, the
gas line connected and tested for leaks and the
initial burner operation has been checked out.
• The size and position of the log set was engi-
neered to give the appliance a safe, reliable
and attractive flame pattern. Any attempt to use
a different log set in the fireplace will void the
warranty and will result in incomplete combus-
tion, sooting, and poor flame quality.
• Logs get very hot and will remain hot up to one
hour after gas supply is turned off. Handle only
when logs are cool. Turn off all electricity to
the appliance before you install grate, volcanic
stone, vermiculite, embers and logs.
• This appliance is not designed to burn wood.
Any attempt to do so could cause irreparable
damage to the appliance and prove hazardous
to your safety.
• If logs are not installed according to the log
installation instructions, flame impingement and
improper combustion could occur and result in
soot and/or excessive production of carbon mon-
oxide (CO), a colorless, odorless, toxic gas.

front of the burner on the ramped sub-floor. In an artistic manner, blend
the vermiculite/volcanic stone mixture into the glowing embers in front
of the log set, to simulate a diminishing ember bed.
Note: Excessive use of embers may result in sooting or poor flame.
This appliance is provided with enough Glowing Embers for several
applications, do not feel compelled to use all that is in a new bag. For

LOG AND GLOWING EMBER PLACEMENT
Step 1. Follow the log placement instructions exactly. Refer to Figures
11, 12 and 13 for detailed log placement instructions.
Step 2. Separate the Glowing Ember (Rockwool) into pieces about the
size of a nickel (see Figure 9 ). Keep the pieces fluffed up with torn edges
and not matted. Distribute these pieces over the burner as shown in
Figure 10. Do not use more than necessary. When properly positioned,
the Glowing Embers may cover the entire burner in front of the front
ports. Do not place embers on main ports in front of the rear log.
Note: Position andirons and secure to the sub-floor before placing
volcanic stone and vermiculite.
