The following are guidelines for placing a gas log set in
a replace that has a restrictive barrier along the bottom
front opening of the replace. Some examples of barri-
ers are glass/screen door frames and sunken/recessed
replaces.
No Restriction 13”
0” 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.
Non combustible material such as refractory brick
may be used to line the oor of the replace 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.
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 replace. Placement
of the receiver outside of the replace will extend the
battery life.
