Do not use more than necessary. The ember
material should cover approximately 65% of
the front burner, with no appreciable gaps or
openings. Make sure the main burner ports
are NOT covered by the ember material.
Step 4. Placement of Logs
All top logs that rest on lower logs, do so over
notches, indents or nubs. Proper log placement
is critical to prevent sooting. Logs should be
placed in the gaps between the flame peaks and
should be positioned so they do not impinge
the flames.
Step 5. Position the individual logs as shown
in Figures 56 and 57. Logs should be placed
in the order shown. All logs that have notches
to fit over the grate tines should be positioned
with these notches directly against the grate.
Handle logs carefully to prevent breakage.
Proper log placement is critical to encourage
outstanding flame appearance and prevent
sooting. When positioned properly as shown,
logs will be positioned between flame peaks
and will not impinge any flames.
Refer to Figure 56 for MPDP35 Series ap-
pliances and Figure 57 for MPDP40 Series
appliances.
Step 3. Separate the Glowing Embers into
pieces about the size of a quarter (Figure 54).
Keep the pieces fluffed up, not matted.
Distribute the pieces over the front surface
of the burner, as shown in Figure 55, but DO
NOT PLACE OVER BURNER SLOTS.
WARNINGS
• DO NOT attempt to install the
logs until the appliance instal-
lation has been completed, the
gas line connected and tested
for leaks and the initial burner
operation has been checked
out.
•
The size and position of the log
set was engineered to give the
appliance a safe, reliable and
attractive flame pattern. Any
attempt to use a different log
set in the fireplace will void
the warranty and will result in
incomplete combustion, soot-
ing, and poor flame quality.
•
Logs get very hot and will
remain hot up to one hour after
gas supply is turned off. Handle
only when logs are cool. Turn
off all electricity to the appli-
ance before you install grate,
volcanic stone, embers and
logs.
•
This appliance is not designed
to burn wood. Any attempt to
do so could cause irreparable
damage to the appliance and
prove hazardous to your safety.
•
If logs are not installed accord-
ing to the log installation
instructions, flame impinge-
ment and improper combus-
tion could occur and result in
soot and/or excessive produc-
tion of carbon monoxide (CO),
a colorless, odorless, toxic
gas.
NOTE: Turn off all electricity to the appliance
before installing volcanic stone, embers,
and logs.
Step 1. Remove the appliance front door (see
Removing Glass Enclosure Panel on Page 32).
Step 2. Install decorative volcanic stone.
Sprinkle the decorative volcanic stone in a
pleasing pattern. The volcanic stone should
be placed directly on top of the firebox bottom,
along the front and to the back at the right and
left sides of the burner. Position any optional
ceramic fiber liners before placing the stone.
Logs should be positioned after the volcanic
stone.
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. Replacement Glow-
ing Embers are available (Catalog Number
88L53).
