Step 9. Installing Logs - Lennox Hearth Products MPDT-3328CPM-B Installation Instructions Manual

Step 9. INSTALL VOLCANIC STONE,
GLOWING EMBERS ANd LOGS
NOTE: Turn off all electricity to the appliance
before you install volcanic stone, embers and
logs. 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 (see
Removing Glass Encloslure panel on page 32.
Step 2. Install decorative volcanic stone -
Sprinkle the decorative volcanic stone in a pleas-
ing 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 Glowing Em-
bers are available (Catalog Number 88l53).

Step 3. Separate the Glowing Ember
(Rockwool) into pieces about the size of a
quarter (Figure 55 ). Keep the pieces fluffed
up, not matted. Distribute these pieces over
the front surface of the burner, as shown in
Figure 56. Do not use more than is neces-
sary. When properly positioned, the Glowing
Embers will cover approximately 65% of the
front burner and with no appreciable gaps or
openings. Ensure that the main burner ports
remain uncovered 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 57, 58 and 59. 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.

WARNING
• DO NOT attempt to install the
logs until the appliance installa-
tion 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 war-
ranty and will result in incomplete
combustion, sooting, 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 appliance before
you install grate, volcanic stone,
vermiculite, 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
according to the log installation
instructions, flame impingement
and improper combustion could
occur and result in soot and/or
excessive production of carbon
monoxide (CO), a colorless,
odorless, toxic gas.
