GENERAL INFORMATION
This log placement guide has been prepared to present detailed log
placement illustrations and provide instruction to assist in the place-
ment of logs at the initial (new appliance) setup and after the annual
cleaning and inspection cycles. The information provided here is to be
used in conjunction with the Homeowner's Care and Operation In-
structions provided together with this document in the appliance lit-
erature packet. Please read the Homeowner's Care and Operation In-
structions completely before completing the procedures detailed in
this placement guide.
INITIAL INSTALLATION CONSIDERATIONS
If the logs are being installed for the first time, the following para-
graphs apply:
DO NOT attempt to install the logs until the appliance installation has
been completed, the gas line connected and tested for leaks and the
initial burner operation has been checked out.
Step 1. Remove the appliance front door.
Step 2. Remove the log set from the interior of the fireplace.
Step 3. Remove the logs from their packaging. Handle logs care-
fully to prevent breakage.
Step 4. MPD-4035 & MPD-4540 Models - Remove the restraining strap
from the grate tines. Ensure the grate is fully inserted into the holes on
the firebox rear panel and over the indents on the firebox floor.
GLOWING EMBERS, VERMICULITE, DECORATIVE VOLCANIC
STONE AND LOG PLACEMENT
Step 1. Separate the Glowing Embers (Rockwool) into pieces about
the size of a quarter (see Figure 1) . Keep the pieces fluffed up, not
matted.
MPD-3328 & MPD-3530 Models -
Distribute these pieces over the burner as shown in Figure 2 . Do not
use more than is shown. The glowing embers should not be placed
directly over the large burner slots as shown in Figure 2 .
MPD-4035 & MPD-4540 Models -
Place the center log (Log No. 1) on the burner as shown on page 2 .
Distribute the glowing ember pieces at the front of the burner as shown
in Figure 3 . Do not use more than is shown. The glowing embers
should not be placed directly over the large burner slots as shown in
Figure 3 .
Note: This appliance is provided with enough Glowing Embers for
several applications; do not feel compelled to use all that is in a new
bag. For best glowing effect, replace the ember material annually. Re-
placement Glowing Embers are available (Catalogue Number 88L53).

Step 2. Mound up a portion of the vermiculite (light colored material)
in front of the burner and grate. Sprinkle the dark colored decorative
volcanic stone on top of the vermiculite in a pleasing pattern.
See
Figure 2 - MPD-3328 or MPD-3530, or Figure 3 - MPD-4035 or MPD-
4540 models.
Note: Your application may not require the use of all of the provided
vermiculite, or decorative volcanic stone. Replacement vermiculite is
available (Part Number 24M4801). Replacement decorative volcanic
stone is available (Part Number 24M4701).
Step 3. Position the individual logs as described on pages 2
(MPD-3328), 3 (MPD-3530) or 4 (MPD-4035 and MPD-4540).

rear of the firebox with the log's notches directly over the brack-
ets. Position the right log (log no. 3) by inserting the pin from the
rear log into the hole on its upper end. Place the left log and then
the smaller left and right top logs. All logs that have notches to fit
over the grate tines should be positioned with these notches di-
