Ember Material Placement
Separate the ember material into small pieces, roughly
1/2" in diameter and place on bracket over front burner
tube. Do not pack down; leave in loose, fluffy condition
for most realistic ember effect. (Fig. 15 & 16)
Lava Rock
The lava rock provided with this fireplace must be
placed on the firebox base on either side of the burner
assembly.
Under no circumstances should lava rock
be placed on any part of the burner
assembly.
First Firing
Upon completing the gas line connection, a small
amount of air will be trapped in the line. When first
lighting the unit with pilot light, it will take a few minutes
to purge the trapped air. Once purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the appli-
ance will not require purging.
When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubri-
cants used in the manufacturing process. After each
lighting, vapor may condense and fog the glass; this
moisture disappears in a few minutes of burning.
Flame Adjustment
For units equipped with Hi/Lo valves, flame adjustment
is accomplished by rotating the Hi/Lo adjustment knob
located near the center of the gas control.

Flame Characteristics
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to the
illustrations below (Figs. 18, 19, 20). If any of the
flames appear abnormal call a service person.

Inspecting the Venting System
The appliance venting system was designed and
constructed to develop a positive flow adequate to
remove flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases (i.e.: carbon monoxide) into the
room.
To inspect the venting system, make sure the main gas
valve is off. Remove the glass panel. Using a flashlight,
check the combustion dome and behind the top grille.
Clean if necessary.
