Minimum Hearth Dimension
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.
No Restriction 14”
0” to 1Z\x” 17”
Greater than 1Z\x” to 3” 17”
Greater than 3” *
*Any barrier greater than 3” placed in front of the gas log
set is not recommended by the manufacturer.
Noncombustible 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.
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.
