IMPORTANT INFORMATION FOR THE INSTAL-
LATION OF THIS GAS LOG SET IN A FIRE-
PLACE WITH A RESTRICTIVE BARRIER
The following are guidelines for placing a gas log set in
a fireplace that has a restrictive barrier along the bottom
front opening of the fireplace. Some examples of barri-
ers are glass/screen door frames and sunken/recessed
fireplaces.
Height of Minimum Depth of
Restriction (x) Fireplace/Firebox
No Restriction 13”
1/” to 1Z\x” 16”
Greater than 1Z\x” to 3” 16”
Greater than 3” *
*Any barrier greater than 3” placed in front of the gas log
set is not recommended by the manufacturer.
NOTE: Non combustible material such as refractory
brick may be used to line the floor of the fireplace in
order to raise the height of the gas log set in relation to
a restrictive barrier. If the unit is raised, the minimum
height dimension listed in the homeowner’s manual must
not be exceeded.
NOTE: If the log set is equipped with a remote receiver,
a restrictive barrier may reduce the battery life by
increasing the ambient temperature inside the fireplace.
Placement of the receiver outside of the fireplace will
extend the battery life.
Barriers such as the bottom of a glass door
frame placed in front of a gas log set can
change the air flow characteristics of the
fireplace which in turn can cause the unit
to overheat and malfunction.
