WARNING
This log set can be installed in a solid fuel burning
fireplace (masonry fireplace or manufactured
fireplace) with a working flue and constructed of
non combustible material or in a vent-free firebox.
Exception: DO NOT install this appliance in a factory-
built fireplace that includes instructions stating that
it has not been tested or should not be used with
unvented gas logs. This log set may be installed as
a vented log set.

The use of thermostat is not allowed on vented log
application. It is only allowed on unvented room
heater classification.
Before Fully Installing the Unit:
Turn OFF the gas supply to the fireplace or firebox.
Seal any fresh air vents and/or ash clean-out doors
located on the floor or wall of the fireplace. If left
unsealed, drafting may cause pilot outage or soot-

chimney flue damper.
Vented Application Installations —
Since, the gas logs are operated with the damper
open, non-combustible material and minimum mantel
