adjustment knob located near the center of the gas 
control valve. (Figs. 64)
Flame & Temperature Adjustment
It is important to periodically perform a visual check 
of the pilot and burner flames. Compare them to the

Ember Material and Lava Rock Placement
Separate the ember material into small pieces, roughly 
1/2” in diameter and place on the front burner tube. Do 
NOT pack down, leave in fluffy, loose condition for most 
realistic ember effect. (Fig. 62)
The lava rock provided with this fireplace 
must be placed on the firebox base 
around the burner assembly. (Fig. 63)
Under no circumstances should this lava 
rock be placed on any part of the burner.
