IMPORTANT INFORMATION FOR THE INSTALLATION OF THIS GAS LOG SET
The following are guidelines for placing a VWF log set in a fi replace that has a restrictive barrier along the bottom front
opening of the fi replace. Some examples of barriers are glass/screen door frames and sunken/recessed fi replaces.
Glass door frames
with adjustable
louvers should have
the lovers
fully open
while the unit is in
operation.
Height of restrictive barrier
caused by glass door frames,
recessed fi replaces, etc. from
the base or bottom surface of the
unit.
(Refer to Table).
The log set should be
placed against or as near
as possible to the rear wall
of the fi replace/fi rebox.
Depth of fi replace/fi rebox.
(Refer toTable).

NOTE: Non combustible material such as
refractory brick may be used to line the
fl oor of the fi replace in order to raise the
height of the gas log set in relation to a
restrictive barrier.
X
Barriers such as the bottom of a glass door frame placed in front of a gas log set can
change the air fl ow characteristics of the fi replace which in turn can cause the unit to
overheat and malfunction. Any deviation from the installation guidelines on this sheet
will potentially void the warranty.
WARNING
If the fi replace has a restrictive barrier
and is equipped with a remote receiver,
it must be placed outside or the
combustion chamber. See “Installing

LOG PLACEMENT
FILLING THE BURNER PAN
Fill the burner pan with vermiculite to the bottom of the rear log and sloped to the front edge of the burner pan. Excess ver-
miculite can spill forward or to the side of the burner pan. Do not overfi ll the propane model. Do not cover the pilot (if SPK
or MVVK is installed) with vermiculite or rock wool (embers).
PLACEMENT OF GLOWING EMBERS (ROCK WOOL)
The Wildfi re fl ame appearance can vary due to differences in draft and fi replace confi gurations and ember placement. After
installing rear (#1) and front logs (#2 and #3), cover the entire top surface of the vermiculite in the burner pan with the rock
wool supplied with unit. Tear the rock wool into pieces approximately
1
/
2
" in size (roughly the size of a nickel) and cover
the burner evenly. Do no use more rock wool than the amount supplied with the unit. To enhance the appearance of the
Wildfi re fl ame, it is recommended to form a mound of rock wool in the center of the burner, 2" to 3" high, visible through
the two front logs.
PLACEMENT OF DECORATIVE VOLCANIC ROCK
Sprinkle volcanic rock in front of front glowing embers and to both sides.
DO NOT SPRINKLE ON BURNERS, EMBER BED, PILOT OR LOGS.
IMPORTANT: Do not handle logs with your bare hands! Always wear gloves to prevent skin irritation
from ceramic fi bers. After handling logs, wash your hands gently with soap and water to remove any
traces of fi bers.

OPERATING INSTRUCTIONS
Figure 28 -
Control Knob
Figure 29 -
Manual Pilot
WHAT TO DO IF YOU SMELL GAS:
• Do not attempt to light any appliance.
• Do not touch any electric switch; do not use any phone in your building.
• Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fi re department.
B.
Use only your hand to push in, or turn the gas control knob. Never use tools. If the knob will not push
in or turn by hand, don't try to repair it. Call a qualifi ed service technician. Force or attempted repair
may result in a fi re or explosion.
C.
Do not use this appliance if any part of it has been under water. Immediately call a qualifi ed service
technician to inspect the appliance and to replace any part of the control system and any gas control
that has been under water.
A.
BEFORE OPERATING smell all around the appli-
ance area for gas. Be sure to smell next to the fl oor
because some gas is heavier than air and will settle
on the fl oor.
If you do not follow these instruction
exactly, a fi re or explosion may result
causing property damage, personal
injury or loss of life.
