PLACEMENT IN A FIREPLACE WITH A RESTRICTIVE BARRIER
IMPORTANT INFORMATION FOR THE INSTALLATION OF THIS GAS LOG SET
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 barriers are glass/screen door frames and sunken/recessed
fireplaces.
Glass door frames
with adjustable
louvers should have
the louvers fully
open while the unit is
in operation.
Height of restrictive barrier
caused by glass door frames,
recessed fireplaces, etc. from
the base or bottom surface of the
unit. (see table).
The log set should be
placed against or as near
as possible to the rear wall
of the fireplace/firebox.
Depth of fireplace/firebox.
(see table).

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.
