Initial Installation Considerations

The packaged logs are located within the firebox. The decorative volcanic
stone and glowing embers are packaged separately in plastic bags located
in the control area of the fireplace.
If the logs are being installed for the first time, the following paragraphs
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.
Proper twig placement is critical to prevent sooting. Twigs should be
placed in the gaps between the flame peaks and should be positioned so
that at no time they impinge the flames.
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 carefully
to prevent breakage.
Step 4. MPb-4035 & MPb-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 Instructions:

Step 1. Separate the Glowing Embers (Rockwool) into pieces about the
size of a quarter (see Figure 7). Keep the pieces fluffed up, not mat-
ted.
MPb-3328 & MPb-3530 Models -
Distribute these pieces over the burner as shown in Figure 8. Do not use
more than is shown. The glowing embers should not be placed directly
over the large burner slots as shown in Figure 8.
MPb-4035 & MPb-4540 Models -
Place the center log (Log No. 1) on the burner as shown on Page 16.
Distribute the glowing ember pieces at the front of the burner as shown
in Figure 9. Do not use more than is shown. The glowing embers should
not be placed directly over the large burner slots as shown in Figure 9.
Note: This appliance is provided with enough Glowing Embers for sev-
eral applications; do not feel compelled to use all that is in a new bag.
For best glowing effect, replace the ember material annually. Replace-
ment 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. For best results,
spread in a non-uniform manner while ensuring complete coverage of
the black sheet metal surface.
See Figure 8 - MPB-3328 or MPB-3530, or Figure 9 - MPB-4035 or
MPB-4540 models.
Note: Do Not place vermiculite or decorative volcanic stone on top of
the gas burner where it will block the burner ports.
Step 3. Position the individual logs as described on Pages 14 (MPB-
3328), 13 (MPB-3530) or 14 (MPB-4035 and MPB-4540).
Note: Your application may not require the use of all of the provided
vermiculite, or decorative volcanic stone. Replacement vermiculite,
volcanic stone and glowing embers is available (see below for ordering
information).
