PLUS DIRECT VENT GAS FIREPLACES (MPD33/35/40/45) • CARE AND OPERATION INSTRUCTIONS
INSTALL VERMICULITE, VOLCANIC
STONE, GLOWING EMBERS, AND LOGS
NOTE:
Turn off all electricity to the appliance
before you install vermiculite, 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 Enclosure panel on
page 11
.
Step 2. Install vermiculite and volcanic stone -
Sprinkle the vermiculite and volcanic stone in a
pleasing pattern. The vermiculite and 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 plac-
ing the vermiculite and volcanic stone. Logs
should be positioned after the vermiculite and
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 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 7 and 8. 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 7 for EDV3530 Series appli-
ances and to Figure 8 for EDV4035 & EDV4540
Series appliances.
Step 3.
Separate the Glowing Ember
(Rockwool) into pieces about the size of a
quarter (Figure 5 ). Keep the pieces fluffed up,
not matted. Distribute these pieces over the
front surface of the burner, as shown in Figure
6. Do not use more than is necessary. 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.
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.
