Before You Begin
It is recommended that prior to installing the LS48THF Logs and
Rock Kit, test re the replace to make sure it is operational.
Proper Log Placement
Log placement is critical to proper burner performance. Logs
must be correctly positioned. The photos in this manual show
the proper pinned position for logs and rocks on this set. Owners
need to be shown proper log and rock placement and instructed
not to move the logs and rocks.
Logs and rocks must t rmly onto the locating pins when
positioned as shown in the photos. Malformed logs, rocks, or logs
with sloppy pin holes must be replaced.
Proper Placement of Crushed Glass Media
This replace is designed to use one layer deep of crushed glass
media on the burner. The maximum amount of crushed glass
media on the burner screen should not exceed 2-1/2 lbs. An
additional 5 lbs. of crushed glass media maybe spread out over
the burner cover and accent light glass panels.
It is recommended that prior to placing the rocks and logs, add
the single layer of crushed glass on the burner screen after only.
Then the remainder of crushed glass media be added after the
log and rock set has been properly installed.

Tools Needed:
Protective Gloves
Phillips Screw Driver or Power Drill with Phillips Drive
Before you begin: Do not, handle these logs with your bare
hands! Always wear gloves to prevent skin irritation. After
handling logs, wash your hands gently with soap and water.
All Logs
The positioning of the logs is critical to the safe and clean
operation of this heater. Sooting and other problems may result if
the logs are not properly and rmly positioned in the appliance.
Refer to Figure 1 for the following warning.
Warning: Failure to position the parts in accordance with this
diagram or failure to use only parts specically approved with
this appliance may result in property damage or personal injury.
Attention: Refer to Pages 4 and 5 Parts List and Parts View to
order logs or rocks.
ROCK AND LOG PLACEMENT
NOTE: Once the installation is complete with the logs, rocks,
and crushed glass media in place, operate the replace to verify
ame appearance. If there are ames directly impinging a log,
turn off replace, then remove the crushed glass media directly
below where the ame impingement occurred. This should
eliminate sooting on the log, and provide a more pleasing ame
appearance.
Installation of the Pins for Log and Rock Placement
The LS48THF Log and Rock Hardware kit includes twelve
8-32x3/4" long self-threading screws, and twelve 9/16" long
spacers. For this log and rock set, only eight screws and spacers
are needed. Install the screws and spacers prior to the log and
rock placement.
Note: It is highly recommended that the replace liner be installed
prior to installing the log and rock spacers so interference with
the locator pins is avoided.
Use a power drill with a Phillips drive to install the screws through
a spacer at each of the eight pilot hole locations provided in the
burner cover. See Figure 1. These will be the locator pins for the
logs and rocks.
Note: If the replace includes the accent light glass panels,
please remove the glass panels prior to installing the Logs and
Rock screws and spacers. Replace the glass panels after the
spacers are installed.
