G. Place the Rockwool
WARNING! Risk of Explosion! Follow rockwool place-
ment instructions. DO NOT place rockwool directly over
burner ports. Replace rockwool material annually. Improp-
erly placed rockwool interferes with proper burner opera-
tion.
H. Place the Lava Rock
See Figure 14.5.
I. Place the Vermiculite
Sprinkle on top of lava rock.
J. Remove Screen Protector
• Tear the corrugated as shown in Figure 14.6. The
corrugated must be separated along the entire top edge
of the protector.
• Slide the screen protector off the screen as shown in
Figure 14.7.
• Rockwool is shipped with this gas appliance.
• Place a small amount of 1/2 in. diameter pieces (dime-
size) rockwool on the burner pan so that the rockwool
touches, but does not cover, the holes in the burner
pan (refer to Figure 14.5). This will provide the “glowing
embers” look.
• It is not necessary to use the entire bag. Save the
remaining rockwool for future use.
