Log Placement Instructions
Models: Charisma - CR18-H, CR24-H, CR30-H

The positioning of the logs is critical to the safe, clean operation of this gas log set. Sooting and other problems may
result if the logs are not properly positioned per these instructions. Failure to position in accordance with the diagrams
below or failure to use only parts specically approved for this log set may result in property damage or personal injury.
WARNING
A. Log Placement (Charisma - CR18-H,
CR24-H, CR30-H)
1. Before installing logs, place rock wool in front of the
grate. Loosely apply nickel size pieces to allow the
gas to ow through for proper burn and not to be
obstructed. Failure to do so would cause a higher
level of CARBON MONOXIDE. See Figure 1.

2. Place log #1 on the right-hand side of the burner
assembly by positioning the pin locator hole on the
bottom of the log over the pin on the right-hand side
of the burner and by rotating the log clockwise toward
the back to contact the rear bend on the sheet metal
of the burner assembly. With the log in place, make
sure that the notch on the bottom of the log match up
with the bracket on the grate. See Figure 2.

3. Hold log #2 with the at surface away from you.
Place log #2 toward the back to the left by positioning
the pin locator hole on the bottom of the log over the
pin on the left-hand side and push back against the
rear bend on the sheet metal of the burner assembly.
See Figure 3.

B. Log Placement (Moxie MX18-H, MX24-H,
MX30-H)
1. Before installing logs, place rock wool in front of the
grate. Loosely apply nickel size pieces to allow the
gas to ow through for proper burn and not to be
obstructed. Failure to do so would cause a higher
level of CARBON MONOXIDE. See Figure 10.

2. Hold log #1 with the pointed end to the left. Place log
#1 behind the grate by positioning the two pin locator
holes on the bottom of the log over the pins behind
the grate. Push the log down to make sure it rests at

C. Log Placement (Dynamo DY16-H,
DY18-H, DY24-H, DY30-H)
1. Before installing logs, place rock wool in front of the
grate. Loosely apply nickel size pieces to allow the
gas to ow through for proper burn and not to be
obstructed. Failure to do so would cause a higher
level of CARBON MONOXIDE. See Figure 19.

2. Place Log #1 on the left-hand side of the burner
assembly by positioning the pin locator hole onto the
log pin on the left-hand side of the burner. When in
place, make sure the at back is ush against the
back of the burner assembly. See Figure 20.
Figure 20 - Log #1 Placement
3. Place Log #2 on the right-hand side of the burner
assembly by positioning the pin locator hole onto
the log pin on the right-hand side of the burner; then
rotate the part to the back. When in place, make sure
the back of Log #2 is up against the bend on the back
of the burner assembly. See Figure 21.

burner assembly. Make sure Log #4 is sitting all the
way down on the burner. See Figure 23.
Figure 23 - Log #4 Placement
6. Hold Log #5 with the at sides of the log facing to the
right. Place Log #5 so the cut out wraps around the
lower right grate tine. Make sure that Log #5 is sitting
on the upper left at area of Log #2. Make sure Log
#5 is rotated to the right as far as possible to avoid
ame impingement. See Figure 24.

PLACE THE DECORATIVE ROCK
The volcanic rocks are shipped with your log set. The vol-
canic rocks may be placed around the unit on the oor of
the rebox. Be sure to avoid any areas on the burner itself.
DO NOT sprinkle volcanic rocks on the logs,
around the pilot, nor near the burners. This
may cause sooting. Place volcanic rocks
only on the oor of the replace.
During initial operation of the new heater,
new burning logs and/or rock wool will give
o󰀨 a paper burning smell and orange ames
will be present. Simply open the windows
for a few hours to vent the odor.
CAUTION
NOTE: For log replacement, please refer to the Installa-
tion/Owner's Manual #4606-900.
