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”
1/2” 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.
